Remitter frequency follows average monthly withholding — new employers generally remit monthly by the 15th of the following month. We quote prior-year payroll correction as one low-cost fixed price — the budget-friendly alternative to hourly billing.
No two prior-year payroll correction files are identical, but the rules that govern them are stable. A tax practitioner who works with Prior-Year Payroll Correction weekly keeps returning to the same anchors, and they are set out below.
One rule does more work than the rest combined, so it goes first. Remitter frequency follows average monthly withholding. A business that grows into the accelerated threshold keeps remitting monthly at its peril. The deadline moves before the CRA writes to say so.
A related rule tends to get overlooked precisely because the first one draws all the attention: Source deductions are held in trust for the Crown. Directors can be assessed personally for unremitted amounts, and that liability survives the corporation. Ask what a reviewer will want to see, and the answer sits in this rule: A worker’s status as employee or contractor turns on control, ownership of tools, chance of profit and risk of loss. It does not turn on what the contract calls them.
What this means for you depends entirely on facts we have not seen yet — which is the honest answer, and the reason a tax practitioner starts every prior-year payroll correction engagement with questions rather than conclusions. What you bring to the table determines how quickly the prior-year payroll correction work proceeds — start with the items below.
We keep the commercial side simple. The fee is fixed and agreed in advance, the file is reviewed with you before filing, and you pay after the service — in that order, every time.

A landscaping company with seasonal staff in Moncton, New Brunswick expanded into a second province. The file already carried long-term contractors who met every test for employment. Every obligation was set up in advance and $71,000 of cash released.
Revenue at a landscaping company with seasonal staff in Moncton, New Brunswick was up sharply and cash was tighter than ever. Underneath it sat long-term contractors who met every test for employment. We reviewed each contractor against the CRA’s control and integration tests and converted those who met the employment tests. We priced the transition before it was forced by a ruling. Every new obligation was set up before it was triggered, not after. That covered registration, remittance frequency and provincial filing. $71,000 of cash was released from the working capital cycle. The expansion completed with every registration and filing obligation covered from day one.
3 years of returns were outstanding at a logistics operator with drivers in three provinces in Brampton, Ontario. That came on top of T4 slips filed weeks after the deadline with no relief request made on the per-slip penalty. Filing on real numbers removed $16,000 of assessed tax.
A logistics operator with drivers in three provinces in Brampton, Ontario had not filed for 3 years. The CRA had issued arbitrary assessments. The business was carrying T4 slips filed weeks after the deadline with no relief request made on the per-slip penalty. That came on top of a growing interest balance. We started with the oldest year and worked forward so each year's closing balances fed the next. We reconstructed vehicle logbooks, calculated the standby charge and operating benefit properly, and amended the affected T4s. We filed the years in sequence rather than all at once. Every year is now filed and assessed on actual figures. The notional assessments were vacated and $16,000 of the estimated balance came off, with a payment arrangement covering the rest.
The ledger at an employer whose remittance frequency moved up a threshold in Hamilton, Ontario could not support its own filings. The reason was a bonus accrued to bring the year-end tax bill down and still unpaid more than a year later. Rebuilding it surfaced $14,500 in unclaimed input tax.
An employer whose remittance frequency moved up a threshold in Hamilton, Ontario could not answer basic questions about its own numbers. A bonus accrued to bring the year-end tax bill down and still unpaid more than a year later sat between the bank statements and the ledger. We reconciled the payroll register, general ledger and T4 summary to the cent, then filed the amended slips. We then documented the process so the work does not depend on any one person remembering how it was done. Records rebuilt and reconciled, $14,500 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
A charity with part-time program staff in Calgary, Alberta faced a $39,000 proposed reassessment. It came after T4s that did not agree to the payroll register or the general ledger. We rebuilt the documentation and the adjustment was withdrawn in full.
A charity with part-time program staff in Calgary, Alberta received a proposal letter opening a review of prior-year payroll correction. The CRA had identified T4s that did not agree to the payroll register or the general ledger. It proposed an adjustment of $39,000, with 30 days to respond. We treated the response as an evidence exercise rather than an argument. We paid the accrued bonus inside the 180-day window and kept the deduction in the year it was accrued. We then indexed every supporting document against the specific line the auditor had questioned. The proposed adjustment was withdrawn in full — all $39,000 of it. The file closed in 10 weeks with no change to the assessed amounts and no penalty.
A restaurant with heavy seasonal turnover in Barrie, Ontario had outgrown its structure. The visible cost was company vehicles used personally with no logbook and no taxable benefit reported. The reorganisation completed tax-deferred and saves $73,000 a year.
A restaurant with heavy seasonal turnover in Barrie, Ontario had outgrown the structure it started with. Company vehicles used personally with no logbook and no taxable benefit reported was the immediate problem. The longer-term one was that the structure blocked the next step. We mapped the current structure and modelled the target. Then we corrected the CPP and EI withholding for the balance of the year. We set the employee up to recover the over-deduction on the personal return. The tax-deferred elections were filed on time and the supporting valuations documented. The reorganisation completed without triggering tax, and the new structure saves approximately $73,000 a year while removing the exposure the old one carried.
A construction firm with union and non-union crews in Regina, Saskatchewan was profitable and permanently short of cash. Behind the gap sat remittances still going out monthly after the business had moved to the accelerated threshold. Restructuring the tax cycle freed $114,000.
A construction firm with union and non-union crews in Regina, Saskatchewan was profitable on paper and short of cash every month. Remittances still going out monthly after the business had moved to the accelerated threshold explained most of the gap. We filed the outstanding slips and summary and requested relief on the per-slip penalty with the reasons documented in writing. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars. $114,000 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.

Same fixed fees in every province. Find your city or your sector.
Direct answers to what Canadian business owners actually ask before hiring an accountant.
Prior-Year Payroll Correction starts at a fixed fee quoted before any work begins. The quote is locked at the outset and does not change mid-engagement, and you pay only after you have reviewed and approved the deliverable. Compare every plan on our transparent pricing page.
At minimum: prior-year returns and notices of assessment, your bank and credit-card statements for the fiscal period, payroll records if you have employees, and GST/HST filings. We send a checklist tailored to your situation after the free 15-minute call.
Most engagements are completed within 3 to 5 business days once your documents are complete. Catch-up work covering multiple years takes longer, and we tell you the realistic timeline before you commit rather than after.
We respond on your behalf at no extra charge for any return we prepared. Every figure we file is supported by documentation retained in your file, which is what turns a CRA review from a crisis into correspondence. See how our CRA audit representation works.
Yes. Late filing penalties compound at 5% of the balance owing plus 1% per month, so the cost of waiting is real. We prioritise catch-up work and, where eligible, file under the CRA's Voluntary Disclosures Program to reduce penalties.
Yes. We serve clients in every province and territory at the same fixed fees, so your location does not change the price or the service. Browse our coverage across Canada to find your city.
We work across construction, healthcare, e-commerce, professional services, restaurants, real estate, transportation, technology and non-profits, each with its own deduction profile and CRA scrutiny patterns. See all industries we serve.
Software applies the rules you already know about. An experienced tax accountant finds the ones you do not: capital cost allowance timing, the small business deduction threshold, shareholder loan repayment rules, and TOSI exposure on family dividends. The fee is usually smaller than the deductions it surfaces.
Our prior-year payroll correction services include complete filing, compliance management, and strategic advice customized to Canadian tax laws.

You are asking the right question, and it has a real answer. Source deductions are held in trust for the Crown from the moment they are withheld, which is why directors can be personally liable for unremitted amounts under section 227.1. Unlike most corporate debts, this one can follow the directors personally after the company is gone. What we add on top of that is the paperwork discipline that makes the answer stand up if anyone ever asks you to prove it.
Let us give you the substance first and the caveats second. Late payroll remittances draw a penalty of 3% to 10% depending on how late. The penalty doubles to 20% for a repeat failure with gross negligence in the same calendar year. The caveat is simply that facts on your file can shift the outcome, so treat this as the baseline rather than the final word.
The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.
Start with the basic personal amount, which is already printed on the form, then add only the credits you genuinely expect to claim, such as tuition you will pay this year, an eligible dependant, the age amount or an amount transferred from a spouse. Total them, sign and date, and give the form to your employer rather than the CRA. With two jobs, claim the amounts at one only. You can also ask for extra tax to be withheld.
Yes. Canada Post charges GST/HST on domestic postage, including stamps, at the rate of the province where you buy them: 13% in Ontario, 5% GST where there is no HST. Postage for mail addressed outside Canada is generally zero-rated, so no GST/HST is charged on it. The tax shows on your receipt rather than in the stamp's face value. Check the CRA's GST/HST rates page for the rate in your province.
Your total deductions are federal tax, provincial tax, CPP and EI. Federal rates for 2026 start at 14% and rise through 20.5%, 26% and 29% to 33%, applied bracket by bracket rather than to your whole salary, and the first $16,452 is sheltered by the 2026 basic personal amount, which tapers at higher incomes. CPP is 5.95% on earnings between $3,500 and $74,600, and EI is $1.63 per $100 to maximum insurable earnings of $68,900.
Start by claiming everything you are entitled to: RRSP contributions, child care, moving and employment expenses, self-employment costs, tuition, medical expenses, donations and the credits that follow your family situation. Timing helps too, such as deferring a bonus or triggering a capital loss against a gain. Pension income splitting and spousal RRSP contributions move income to a lower-rate spouse. For a business, incorporating and planning how money is drawn out matters. Leaving income unreported is evasion, not planning.
No. Age creates no exemption. Income tax is withheld from a young worker’s pay in the usual way, though many earn less than the basic personal amount and recover the withheld tax by filing a return. EI premiums apply at any age. CPP contributions begin with the month after the worker turns 18, so no CPP comes off before then. Filing anyway is worth it, because earned income builds RRSP room for later.
Federally, no. Employer contributions to a private health services plan covering medical, dental and hospital care are not a taxable benefit, so they do not show up in your income. Quebec taxes them provincially, which is why a Quebec slip can show an amount the federal one does not. Premiums you pay yourself, including the employee share deducted from pay, can count as medical expenses on your T1. Group life and some wage-loss plans are treated differently.
There is no single figure, because tax is built band by band on your own income. For 2026 the federal rates start at 14% and rise through 20.5%, 26% and 29% to 33%, each applying only to the income inside that band, and your province adds its own brackets on top. A federal basic personal amount of $16,452 for 2026 shelters the first slice, tapering to $14,829 at higher net income. Deductions and credits reduce the result further.
Yes. Toilet paper is an ordinary household product, not a basic grocery, so GST/HST applies at the rate for the province of purchase: 5% GST in Alberta, 13% HST in Ontario, 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 14% in Nova Scotia from 1 April 2025. Provincial sales tax may apply on top in British Columbia, Saskatchewan, Manitoba and Quebec.
Yes. The CRA answers individual, business and benefit enquiries by phone, and its Contact the CRA page lists the current numbers and hours for each line. Have your social insurance number or business number, a recent return and your notice of assessment ready, because the agent will verify your identity before discussing an account. For account details, balances and slips, My Account often answers the question faster than the phone.
Taxable income covers employment income and taxable benefits, self-employment and side income, tips, pensions and registered plan withdrawals, EI and most government support payments, interest, dividends, the taxable part of capital gains, rental profit, and foreign income earned while resident here. Residents report worldwide income, and the absence of a slip does not make an amount exempt. Taxable income is what remains after the deductions you qualify for, and the rates apply to that figure.
Yes. Canada uses a social insurance number rather than a social security number, and if you are not eligible for a SIN you can apply to the CRA for an individual tax number and file with that. Apply before or together with your first return, and allow processing time. Without one of those identifiers the CRA cannot match the return to you. Non-residents with Canadian income most often file using an individual tax number.
You cannot appeal the tax rate, but you can challenge the assessed value the tax is calculated on. Each province has an assessment authority that issues a notice of assessed value, and a request for reconsideration or an appeal must be filed with it by the deadline printed on that notice. Support the claim with recent selling prices of comparable properties and evidence of anything that reduces value. A successful reduction adjusts the tax for the years in question.
