Fee-for-Service Billing, Overhead and the Physician's Irregular Income

You see patients on a Tuesday in March. The provincial plan pays you for that Tuesday weeks later, on a date it publishes in advance, and only for the claims it accepts. Your clinic rent, your staff and your share of the overhead leave on the first of every month. Your tax instalments arrive on four fixed dates. Three calendars, and none of them waits for the others.

That is the real shape of fee-for-service income. It is not low, and over a whole year it can be fairly predictable. It is uneven inside the year: a four-week holiday produces no billings, a refused batch of claims arrives a statement later, a conference week bills nothing, and an illness bills nothing for as long as it lasts. The overhead does not take a holiday with you.

What follows is a practical method: how the money moves from the claim to your account, why taxable income and cash part ways, and how to size a reserve by testing it against a bad year. Then come the ways a trough can be covered, from your own reserve to a loan from an insurer against a policy you already own, with what each one costs.

I am paid by insurer commissions when a policy is bought, so you should know that before you read the part about policies. Reading costs you nothing. And one point belongs at the start: a life insurance policy is not something to buy to smooth next quarter's billings. If you need permanent life insurance for its own sake, the policy can play a role later. The reserve comes first either way.

Why does fee-for-service income arrive so unevenly?

Because you are paid per insured service you bill, on the plan's payment dates, and only for claims it accepts. When you are not working, nothing is billed. Holidays, illness, parental leave, training and refused claims all leave gaps, while overhead and household costs keep running every month.

Fee-for-service means the provincial plan pays a fee for each insured service you bill, at rates set by the agreement in your province. In Quebec that plan is the Régie de l'assurance maladie du Québec (RAMQ); in Ontario it is the Ontario Health Insurance Plan (OHIP); in British Columbia it is the Medical Services Plan (MSP). Other payment methods exist, such as sessional rates or blended models; the principles below apply wherever part of your income depends on what you bill.

Five things make the cash uneven, and each calls for a different fix.

• Time off bills nothing. A holiday, a conference, a course, a parental leave or an illness produces no claims for as long as it lasts. An employee keeps a salary through paid vacation. You do not.
• Payment comes later. The plan pays on its own calendar, after your claims are received and processed. The work of one month becomes cash in a later one.
• Some claims come back. A claim with an error, a missing element or a code the plan disputes is refused or held. It returns on your statement and has to be corrected and sent again, which moves that money further out.
• The rules can change. Fees, billing codes and payment methods are set by agreements between provincial governments and the physicians' federations or associations, and by provincial law. When they change, your billings for the same work can change too.
• Costs keep their own rhythm. Rent, staff, equipment leases, professional fees and insurance premiums arrive monthly or yearly, whatever you billed.

None of this is a reason for alarm. It is a reason for a system. A physician who reads only the annual total can be short of cash in a good year.

How long is the gap between seeing a patient and being paid?

It depends on the province and on how fast your claims go in. Each plan sets a deadline to bill and its own payment dates. Quebec's RAMQ publishes a payment calendar with reception deadlines; British Columbia's MSP pays twice a month; Ontario sets a three-month window to submit claims.

The table below gives the rules as each official source states them, read on 2 October 2026. It does not give processing times, because those depend on the batch, the claim and the period.

Two points in that table deserve a closer look.

First, Quebec's deadline. RAMQ's notice of 5 December 2025 says the billing deadline in section 22.1 of the Health Insurance Act goes from 90 to 45 days for services rendered from 1 January 2026, calculated from the date of service, and that deadlines to modify, rebill or cancel do not change. The same notice says a bill was adopted to postpone provisions of Loi 2 to 28 February 2026. RAMQ's billing calendar page, read on 2 October 2026, shows 90 days in its table, and so does RAMQ's billing guide for specialists dated 16 June 2026, the most recent of the three documents. So, as of that reading, 90 days is what RAMQ's own current guides state. Rules can change again, so before you rely on that figure, read the deadline that applies to your date of service on RAMQ's own site. The safe habit does not depend on the answer: bill every week, not every month.

Second, Ontario's window. The billing brief published by the Ministry of Health and the Ontario Medical Association, updated 17 January 2025, says claims beyond three months are stale-dated and that the ministry may refuse them. It accepts late claims only for extenuating circumstances, such as a serious illness requiring hospitalization; a misfiled claim is not one.

Elsewhere, find the same three facts for your plan: the deadline to bill, the payment dates and the deadline to correct a refused claim.

Why is the income you earned this year not the cash you received?

Because the tax rules count professional income when it is earned, not when it is paid. The Canada Revenue Agency requires the accrual method for self-employed professional income, so December's services paid in January belong to December's year. Your taxable income and your cash in a year can differ.

The Canada Revenue Agency's page on accounting methods, modified 31 August 2026, says it plainly: under the accrual method you report income in the fiscal period you earn it, no matter when you receive it. Farmers, fishers and self-employed commission agents may use the cash method. All other self-employment income must be reported using the accrual method.

For a physician who bills a plan, the work done in the last weeks of the year is income of that year even if the payment lands in the new one. Three consequences follow.

• A strong December raises this year's tax and next year's cash. Tax is computed on work not yet paid for.
• A long holiday at year-end does the reverse: thin January receipts, with the tax for the year just ended still to pay.
• Refused claims sit in between. Whether a claim that was billed and later refused counts, and when, is a question for your accountant, who works from the statements of account.

Through a professional corporation, the corporation's income follows its own fiscal year, and your personal income is the salary or dividends it pays you; that is covered further down.

What does overhead look like against billings that move?

Overhead is the part of your costs that does not stop when you do. Rent or a share of clinic costs, staff, equipment, professional fees and insurance keep running in a month with no billings. Separate the fixed part from the part that moves with volume, because only the fixed part needs a reserve.

In a group clinic you may pay a share of costs set by the clinic agreement; in your own office you pay them directly. Joining a clinic or a group practice looks at how that agreement shapes your costs. Here the question is simpler: which costs keep running when you are away?

Two notes on that table. Professional liability protection can be a large yearly cost, and reimbursement programs for part of it may exist under the agreement with the physicians' federation or association in your province; check what applies to you before you put the full figure in your worksheet. And an overhead expense policy, if you own one, can pay certain fixed office costs during a disability after its waiting period, under its own definitions. It does not cover a holiday or a slow month. The physician page on disability and the capital plan explains how that cover and your reserve fit together.

The test for every line: would it still be paid in a month when you billed nothing? If yes, it is fixed overhead.

How do tax instalments fit into an uneven year?

If your net tax owing was large enough in recent years, you pay instalments on four fixed dates, whatever you billed that quarter. The Canada Revenue Agency's threshold is $3,000, or $1,800 for Quebec residents; Revenu Québec has its own instalments. Set tax aside from every receipt so the dates do not catch you short.

The federal rules, from Canada Revenue Agency pages read on 2 October 2026:

• Who pays. The page on required tax instalments for individuals, modified 20 January 2026, says you may have to pay instalments if your net tax owing is more than $3,000 (for Quebec, $1,800) in 2026 and in either 2025 or 2024.
• When. Instalments are due on March 15, June 15, September 15 and December 15.
• How much. The CRA offers three options: no calculation, prior year and current year. The current-year option suits a year very different from the last two, but an estimate that proves too low bears instalment interest, compounded daily at the prescribed rate, which can change every three months.
• Year-end. The CRA's page on 2026 tax deadlines for businesses and self-employed individuals, modified 15 May 2026, gives June 15, 2026 as the filing deadline for self-employed individuals and April 30, 2026 as the deadline to pay any balance owing.

In Quebec, you also deal with Revenu Québec. Its page on instalment payments says instalments are required when your net income tax payable is over $1,800 for the current year and was over $1,800 for either of the two previous years. For a self-employed person, those instalments can also cover the Quebec Pension Plan contribution, the contribution to the health services fund and the Quebec parental insurance plan premium.

The practical answer for irregular income is a separate account for tax. Each time the plan pays you, move a fixed share of the receipt, after overhead, into that account and leave it there until an instalment or the balance is due. Ask your accountant to set the share and to check it at mid-year. A tax account topped up from every receipt turns four hard dates into four routine transfers.

How do you build a monthly cash worksheet?

List twelve months. For each one, enter the payments you expect from the plan, by payment date, then subtract fixed overhead, the tax set-aside and the household's draw, in that order. The running total shows the lowest point of your year, and that low point sizes your reserve.

Name each input and where it comes from.

1. Expected receipts. Your billings for each period of service, moved to the payment date on which you expect them. Source: your billing history and the plan's payment calendar. Use what you were actually paid in past months, not what you billed, so that refusals and corrections are already in the figure.
2. Fixed overhead. Every cost from the overhead table that runs whether you bill or not. Source: the clinic agreement, the lease, payroll and the annual notices. Spread yearly costs over the months in which you will actually pay them, not evenly, if they fall due at once.
3. Tax set-aside. A share of each receipt, after overhead, moved to the tax account. Source: your accountant, who sets the share from your tax position and province.
4. Household draw. What the household needs each month for living costs, debt payments and savings. Source: your own records. This is the one line fully in your control.
5. Monthly flow and running total. Receipts less the three lines above, in that order, then added month by month. The lowest running total of the year is the amount your reserve must cover.

The order matters. Overhead is owed whether or not you were paid. Tax was earned with the receipt. The household draw comes last because it is the line you adjust when a month is short.

Run it first on last year's real figures. Where the worksheet and what actually happened disagree, trust what happened.

What does the worksheet show on an illustrative year?

In the illustrative example, a year with $315,000 of receipts needed a reserve of $5,800 when the four-week holiday fell in July and $20,100 when it fell in February. Adding a six-week absence pushed the low point to $30,800 and left the year $12,000 short. Size your reserve on the stress test.

Illustrative example. Every figure is an assumption chosen to show the arithmetic; none comes from a provincial fee schedule, a clinic agreement or a tax table. Assumptions:

• You are self-employed and bill $30,000 of services in a normal month, and the plan pays each month's services in the following month.
• You take four weeks off in July and two weeks in December, so July bills nothing and December bills $15,000. The previous December also billed $15,000, so January receives $15,000.
• Fixed overhead is $9,000 a month.
• The tax set-aside is 30% of each month's receipts after overhead, and nothing when receipts do not cover overhead. The 30% is an assumption for the example, not a tax rate; your accountant sets your own share.
• The household draws $10,000 a month.

In a normal month the arithmetic is $30,000 received, less $9,000 of overhead, leaves $21,000; 30% of that, $6,300, goes to the tax account; less the $10,000 household draw leaves $4,700. In January, $15,000 received less $9,000 leaves $6,000, less $1,800 set aside and $10,000 drawn: a shortfall of $5,800. In August, nothing is received: a shortfall of $19,000.

Then two stress tests on the same assumptions. In the first, the four-week break moves from July to February, so March receives nothing. In the second, the July break stays and you are also away for six weeks, billing nothing in March and $15,000 in April, so April receives nothing and May receives $15,000.

Read the bottom row first. The base year and the first stress test both end $22,200 ahead, with $64,800 in the tax account. The lowest point differs: $5,800 in January for the base year, $20,100 in March when the break comes early, before the good months have built a cushion.

The second stress test changes the year itself. Receipts fall to $270,000, the tax set-aside to $54,000, and the household draw, left unchanged, takes the year to $12,000 short. The lowest point is $30,800, in August. That is the year a reserve exists for, and it is also the year in which the household draw has to be cut, because no reserve can carry an annual shortfall forever.

Three lessons come out of the arithmetic.

• Timing decides the reserve. The same billings needed more than three times the cushion when the gap came early.
• The good months are not spare money. In the base year, the $22,400 built up by July is what carries August. Spend it in June and August becomes a borrowing month.
• An illness is not a holiday. An absence you did not choose has no end date, and your disability coverage and its waiting period decide how long the reserve must last.

How large should the reserve be, and where should it sit?

Large enough to cover the lowest point of your worst reasonable stress test, kept apart from the tax account, and reachable within days. Where it sits is a separate choice: a savings account, a registered account or other options each do a different job, and the speed of access matters more than the rate.

The reserve is that low point plus a margin for what the worksheet did not foresee: a refused batch, a rule change, a repair. The margin is your judgment; write down why you chose it.

Then decide where the reserve sits. Three questions matter more than the interest it earns.

• How fast can it reach your chequing account? A reserve you cannot reach before the rent is due does not do its job.
• Is it kept apart from the tax account? Money set aside for tax is not reserve money, even when the two sit side by side in your mind.
• What does taking it out cost? Some places charge to withdraw early; registered plans have their own rules on withdrawals and on putting money back. A Tax-Free Savings Account and an RRSP do different jobs from a cash reserve and from a life insurance policy, and this practice gives no order between them. Questions about registered plans belong with a representative registered for the investments the plan would hold, or with your accountant.

If you practise through a corporation, the reserve may sit in the corporation instead of the household, and its form affects the corporation's tax. The silo page on the corporate reserve compares the places an incorporated business can keep it, one feature at a time.

Two habits keep a reserve honest: refill it before you raise the household draw, and when you use it, write down the month it will be whole again.

Which routes can cover a trough, and what does each one do?

Your own reserve, a line of credit, a credit card paid in full, a loan from an insurer against a policy you already own, or a loan from a lender secured by that policy. Each does a different job, at a different cost, with a different person deciding the terms. None of them makes a shortfall disappear.

The table compares the routes by what they do, not by their rates, because every rate belongs to a specific agreement and changes over time.

A line of credit is arranged with a lender while your income is strong, not during the bad quarter; whether you need one, and how large, depends on your worksheet.

The two policy routes exist only if you already own a policy with enough loan value. A new policy has little of it in its first years, so it cannot cover this year's trough. That is why capitalization comes before use.

And every borrowed route is debt: the month after the trough, your worksheet carries a repayment line.

How does a policy loan work as a bridge for a slow quarter?

If you own a participating whole life policy with loan value, the insurer can advance money against it. The insurer is the lender, sets the rate and may change it, and receives the interest. The cash value is the security. The loan can be taxable above the adjusted cost basis, and an unpaid loan reduces the death benefit.

A policy loan is an advance the insurer makes from its own funds, with the policy's cash value as security. You, as the owner, request it under the contract's loan provision; the insurer confirms the amount available and any consent the contract requires, for example from an irrevocable beneficiary or from a lender holding an assignment. The Autorité des marchés financiers describes it as borrowing with the insurance's cash surrender value as collateral, repaid with interest, and says that if you die before it is repaid the insurer subtracts the amounts owed and the accrued interest from the insurance payable.

Each part of that has a consequence for a bridge loan.

• The interest is a real cost, paid to the insurer. The rate is set by the insurer and may change while the loan is outstanding. Depending on the contract, interest you do not pay can be added to the loan and then bear interest itself.
• The loan can create taxable income. Under s. 148(9) of the Income Tax Act, a policy loan is a disposition of an interest in the policy. The part of the loan above the policy's adjusted cost basis immediately before the loan is income in that year, and the loan lowers the basis. Repaying a loan that was taxed can give a deduction under paragraph 60(s) in the year you repay, up to the amount previously included; it is a deduction in that year, not a refund of the earlier tax. Ask the insurer for the basis before each loan; the page on when a policy loan becomes taxable works through the calculation.
• The death benefit is reduced until you repay. Whatever is owed at death comes off what the beneficiary receives.
• The policy can end if the loan outgrows the value securing it. If the loan and its interest overtake that value, the contract can end under its terms. That ending is a disposition, and it can create income to the extent the proceeds, which take the loan into account, exceed the adjusted cost basis, even when little cash is paid out.
• Deductibility depends on the use of the money. Under paragraph 20(1)(c) of the Income Tax Act, interest can be deductible when the money is used to earn income from a business or property, and subsection 20(2.1) also requires the insurer to verify policy loan interest on form T2210, Verification of Policy Loan Interest by the Insurer. Household living costs do not meet that test; practice overhead may. Your accountant traces the use first.

Illustrative example, comparing interest only, on the same trough as the second stress test. You need $30,000 to carry the household through the absence and repay $3,000 a month once billings resume. Interest is calculated monthly on the declining balance; your contract or credit agreement may calculate it differently, for example once a year on the policy anniversary, which changes the figure. The rates are assumptions, not quotes from any insurer, lender or card issuer.

In interest alone, drawing your own reserve costs the least, which is one more reason to build it first. Among the borrowed routes, the comparison depends on the actual rates you are offered on the day. A policy loan's case rests elsewhere: no credit application to a lender, a repayment schedule you set, and the cash value left in the contract as security. That freedom is also its risk; write the repayment into your worksheet the day you take the loan.

Does incorporation change the cash-flow picture?

It changes who holds the reserve and how you pay yourself, not when the plan pays. The corporation waits for the same payment dates and pays the same overhead. Income it keeps is taxed under corporate rules, and moving money to you is a second transaction, with its own tax.

Four sets of tax rules shape money left in a corporation, and each one changes the arithmetic. The Canada Revenue Agency's T2 Corporation Income Tax Guide, chapter 4, modified 28 May 2026, gives the small business deduction's business limit as $500,000 for a corporation not associated with any other, and reduces it when a Canadian-controlled private corporation and its associated corporations earn $50,000 to $150,000 from passive investments, to nil above $150,000. The personal services business rules can deny the small business deduction where the person doing the work would otherwise be regarded as an employee of the corporation's client; your accountant checks whether they reach any part of your income. And in Quebec, Revenu Québec's tax news of 4 May 2026 confirms that the reduction of the provincial small business deduction rate based on the number of remunerated hours remains unchanged. Federal rules apply everywhere; a Quebec corporation also files with Revenu Québec.

With those rules in view, incorporation changes three things for a physician with uneven billings.

• The reserve can sit in the corporation, taxed at corporate rates, and how it is held affects the passive income measure; see incorporated physicians and retained earnings for depth.
• Your pay can be steadier than your billings. The corporation can pay a regular salary or dividends on a schedule set with your accountant, absorbing the uneven months; salary, dividend and the contract compares them.
• A corporate policy loan is the corporation's debt. If the corporation owns a policy, a loan on it is an advance from the insurer to the corporation. Getting that money to you is a second transaction, such as salary, a dividend or the repayment of a shareholder loan, with its own tax.

There is no general answer to who should own a policy, if any: you personally, your medical professional corporation and a holding company each give different results, and the choice belongs with your accountant and your lawyer (in Quebec, a lawyer or a notary). Provincial rules on who may own the shares of a medical professional corporation also apply; ask the college and a lawyer.

What is different for a physician in Quebec?

The plan is RAMQ, the agreements are negotiated by the FMOQ for family physicians and the FMSQ for specialists, the Collège des médecins du Québec regulates practice, and Revenu Québec runs its own tax and instalment system. Each one has a calendar to put on your worksheet.

Several Quebec bodies touch the cash flow of a fee-for-service physician.

• The Régie de l'assurance maladie du Québec (RAMQ) receives your claims, publishes the payment calendar and its reception deadlines, sends your statements of account and sets the deadlines to bill, correct and ask for a review. Its calendar page gives 90 days from the statement of account to ask for a modification of a fee-for-service claim or a review.
• The Fédération des médecins omnipraticiens du Québec (FMOQ) and the Fédération des médecins spécialistes du Québec (FMSQ) negotiate the agreements with the government that set fees and payment methods. Physician remuneration in Quebec is also shaped by legislation that RAMQ's notices call Loi 2, and the notice of 5 December 2025 says some of its provisions were postponed to 28 February 2026. For the rules in force on a given date, read RAMQ's notices and your federation's information to members.
• The Collège des médecins du Québec regulates the practice of medicine, including practice through a company. Ask it, and a lawyer, about any structure before you set one up.
• Revenu Québec collects provincial income tax and your instalments, which for a self-employed person can include the QPP contribution, the health services fund contribution and the QPIP premium.

Put a reminder in your calendar the day each statement arrives, because the review window runs from it: a refused claim not corrected in time is income you earned and will not receive.

What are the drawbacks and risks of each approach?

A reserve has an opportunity cost and depends on your discipline to refill it. Borrowing turns a gap into debt. A policy loan adds interest paid to the insurer, possible tax, a reduced death benefit and lapse risk. And a policy bought for cash flow can strain the very months it was meant to help.

• The reserve earns little and can be spent. A reserve quietly spent in a good month is gone when the bad one comes.
• Borrowing defers the gap. A line of credit or a loan carries the trough into the next months, with interest. If the shortfall is annual, as in the second stress test, borrowing only postpones a change to the household draw.
• A policy loan can be left unpaid. Interest added to the loan grows the balance. The death benefit shrinks. If the loan overtakes the value securing it, the contract can end, with possible tax.
• The insurer can change the loan rate, depending on the contract, and dividends on a participating policy are not guaranteed. A plan that only works with a particular dividend is fragile.
• Premiums are a fixed cost too. If you own a policy, its premium belongs in the fixed overhead line of your worksheet. A policy surrendered in its early years can return less than was paid in. The page on the real costs sets out what those early years cost.
• Insurer solvency is supervised by charter. A federally incorporated insurer is supervised by the Office of the Superintendent of Financial Institutions; a provincially incorporated one by its home province, the AMF in Quebec. Assuris protects policyholders of its member insurers within limits: on its whole life page, up to $1,000,000 or 90% of the death benefit and up to $100,000 or 90% of the cash value, whichever is higher, calculated after policy loans.

What should you ask before you act?

Ask your billing agent for monthly figures, your accountant for the tax share and the instalment method, and the insurer, in writing, for the loan provision and the adjusted cost basis. Then ask yourself whether you will refill what you use, and whether a lender's line of credit belongs in the plan.

For your billing agent or your own billing records:

1. How much did I bill, for which dates of service, and how much was paid on each statement?
2. Which claims were refused, why, and by what date must each correction go in?
3. Is any claim near its billing deadline?

For your accountant:

1. What share of each receipt should go to the tax account, and which instalment option suits my year?
2. How will services provided late in the year, and paid in the next one, be reported?
3. If I am incorporated, what pay schedule smooths my household income, and at what tax cost?

For the insurer, if you already own a policy, in writing through your representative:

1. How is the loan rate set, and can it change?
2. Is interest charged monthly or on the anniversary, and what happens to unpaid interest?
3. How much can I borrow today, and are any consents required?
4. What is the adjusted cost basis today, and what income would you report on the loan I have in mind?
5. What happens as the loan approaches the value securing it?
6. How are you, and the representative, paid on this policy?

And for yourself: what is the lowest point of my worksheet under a stress test, and in what month will each amount I borrow be repaid?

How should you read these figures?

Every number in the illustrative examples is an assumption, including every interest rate; none comes from any plan, insurer or lender. The figures that come from official sources (deadlines, thresholds and dates) are given with their source and the date they were read, and they can change; check them again before you rely on them. The worksheet's method is the point. Replace each assumption with your own billing history, your clinic agreement and your accountant's set-aside, and run the same two stress tests.

The other pages for physicians in this series build on the same worksheet. Starting out with residency debt is covered in new physicians, residency debt and what to do first, and the risk of an absence with no end date in disability and the capital plan. Every article for doctors is gathered on the physicians page, and the wider business owners section covers the corporate rules in depth. Other professionals with uneven pay face the same arithmetic: see real estate agents and irregular income.

Who this does not suit

The policy part of this approach does not suit you if you do not yet have a cash reserve and a tax account, if you carry expensive debt you cannot pay down, or if you could not keep a premium going through a slow year. It does not suit you if you would not repay a loan that no one schedules for you, or if your plan only works with a particular dividend. And it does not suit you if a reserve and a line of credit already cover your stress test comfortably; that is a sound place to stop.

It can suit you if your worksheet is in order, you need permanent life insurance for its own sake, you can carry its premiums through the uneven months, and you want a source of financing you can repay on your own schedule after the policy has had years to build. If that describes you, start with the self-check on the Becoming a Client page.
