There is a version of customs excise and commodity tax coordination that runs smoothly and a version that turns into correspondence. The difference is rarely luck; it comes down to details any tax expert handling these files weekly learns to check first.
There is no way around the opening fact, so it may as well come first. Place-of-supply rules decide the rate: for most services it follows the customer’s address on file. A supplier in a 5% GST province can therefore owe 15% HST on a sale to Atlantic Canada.
Pair that with the next rule and most of the confusion around customs excise and commodity tax coordination disappears: Input tax credits generally have a four-year claim window for smaller registrants, but the documentation the CRA requires scales with the invoice amount. One more rule deserves attention, mostly because ignoring it is expensive in ways that only show up later. A business making both taxable and exempt supplies can only recover input tax on the taxable side. The allocation method has to be reasonable and applied consistently.
In practice, this is why customs excise and commodity tax coordination rewards a tax expert rather than a generic preparer: each of these points is a judgement call before it is a keystroke. To move quickly, have your ledger exports, bank statements and prior filings ready when we start.
You will see the finished work before it goes anywhere — review-before-filing is standard here, not an add-on. The fee is fixed up front, and nothing is payable until the service is done.

A residential landlord also renting commercial space in Saskatoon, Saskatchewan was filing correctly and still overpaying. The reason was HST charged at the home-province rate on sales into four different provinces. Restructuring the position cut $34,500 from the annual bill.
A residential landlord also renting commercial space in Saskatoon, Saskatchewan was compliant but paying more than it needed to. The prior year had been filed correctly. It still left HST charged at the home-province rate on sales into four different provinces on the table. We modelled the current position against the alternatives before changing anything. Then we rebuilt the sales ledger by customer province and applied the correct place-of-supply rate to each stream. We filed corrected returns before the CRA opened a review. The change saved $34,500 in the first year and repeats annually. Nothing about the filings became more aggressive. The position is simply the one the rules already allowed.
A marketing agency billing outside its home province in Hamilton, Ontario had outgrown its structure. The visible cost was input tax credits claimed on the exempt side of a mixed-supply business. The reorganisation completed tax-deferred and saves $22,000 a year.
A marketing agency billing outside its home province in Hamilton, Ontario had outgrown the structure it started with. Input tax credits claimed on the exempt side of a mixed-supply business 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 filed the section 156 election for the related registrants, so supplies between them stopped carrying tax that served no purpose but cash-flow drag. 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 $22,000 a year while removing the exposure the old one carried.
Growth at a health clinic making exempt supplies in Edmonton, Alberta had outrun the back office. A sales tax account filed annually while the CRA had moved the business to quarterly broke first. Headcount reached 64 with $136,000 of cash freed.
A health clinic making exempt supplies in Edmonton, Alberta was growing fast, with headcount reaching 64 in eighteen months. The back office had not kept up. A sales tax account filed annually while the CRA had moved the business to quarterly was the first thing to break. We backdated the registration to the date the business stopped being a small supplier, remitted the tax owing, and applied for relief on the penalty portion. We built the compliance calendar for the size the business was becoming rather than the size it had been. The business reached 64 staff with no missed remittance and no late filing. $136,000 of working capital was freed in the process.
A $60,000 reassessment landed at a restaurant group in Calgary, Alberta. It rested on a commercial property purchase closed on the assumption no tax applied because the vendor was not registered. The objection was allowed in full.
A restaurant group in Calgary, Alberta had been reassessed for $60,000. 18 days were left on the objection deadline. The reassessment rested on a commercial property purchase closed on the assumption no tax applied because the vendor was not registered. We filed the objection inside the deadline with a complete submission rather than a placeholder. Alongside it, we self-assessed the tax on the real property acquisition in the correct reporting period and claimed the offsetting input tax credit in the same return. The appeals officer allowed the objection in full. $60,000 was reversed and the account returned to a nil balance.
A multi-province online retailer in Guelph, Ontario faced a $142,000 proposed reassessment. It came after a registration threshold crossed nine months before anyone registered. We rebuilt the documentation and the adjustment was withdrawn in full.
A multi-province online retailer in Guelph, Ontario received a proposal letter opening a review of customs excise and commodity tax coordination. The CRA had identified a registration threshold crossed nine months before anyone registered. It proposed an adjustment of $142,000, with 30 days to respond. We treated the response as an evidence exercise rather than an argument. We set a defensible input tax credit allocation between taxable and exempt supplies and documented the method for future filings. We then indexed every supporting document against the specific line the auditor had questioned. The proposed adjustment was withdrawn in full — all $142,000 of it. The file closed in 10 weeks with no change to the assessed amounts and no penalty.
A manufacturer exporting to the US in Moncton, New Brunswick had already been penalised. The issue was export sales zero-rated with no shipping documentation behind them. A relief application cancelled $60,000 of that penalty.
A manufacturer exporting to the US in Moncton, New Brunswick had already missed one deadline and was about to miss a second. Behind it sat export sales zero-rated with no shipping documentation behind them. A penalty of $60,000 was accruing. We split the work into what had to happen before the deadline and what could follow it. Then we brought the nil and missing periods current so the account was clean before the refund claim was filed. The outstanding return was accepted as filed, and the taxpayer relief application cancelled $60,000 of the penalty already assessed on the earlier year.

Direct answers to what Canadian business owners actually ask before hiring an accountant.
Customs Excise and Commodity Tax Coordination 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 customs excise and commodity tax coordination services include complete filing, compliance management, and strategic advice customized to Canadian tax laws.

Place-of-supply rules decide the rate: for most services it follows the customer’s address on file. A supplier in a 5% GST province can therefore owe 15% HST on a sale to Atlantic Canada. That is the part most owners have not heard before they sit down with us, and it usually changes what they do next.
We get this one a lot, and the answer is more concrete than people expect. Registration becomes mandatory once taxable supplies exceed $30,000 in a single calendar quarter or over four consecutive quarters. Exceeding it in one quarter makes the sale that crossed it taxable. Over four quarters, you stop being a small supplier at the end of the month after the fourth quarter. Bring your documents and we will show you where it lands in your numbers.
The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.
CRA online filing for 2025 returns opened 23 February 2026 and closes 29 January 2027. Most people file between late February and the 30 April 2026 deadline, and that stretch is what tax season refers to. You can gather documents and prepare a return earlier, but it cannot be sent electronically before the system opens. Employment and investment slips such as T4 and T5 are issued by payers early in the year, and the CRA's Auto-fill service can pull the ones it already holds once you have set up My Account.
The GST rate is 5%, unchanged since 1 January 2008 and current for 2025 and 2026. It reaches every province and territory, but in five provinces it is folded into the HST: you charge 13% in Ontario, 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 14% in Nova Scotia, down from 15% on 1 April 2025. In Alberta, the Northwest Territories, Nunavut and Yukon, 5% applies alone.
Restaurant meals are taxable across Canada. In HST provinces a single combined rate applies to the bill; where the province levies its own separate sales tax, GST applies and the province decides whether prepared meals and alcohol carry provincial tax as well. A tip you choose to add is not taxed. The rate turns on the province of supply, so check the combined rate for the province the restaurant operates in.
Divide the total by one plus the tax rate, then subtract that result from the total to get the tax. In Ontario at 13% HST divide by 1.13; in Nova Scotia at 14% from 1 April 2025 divide by 1.14; where only 5% GST applies divide by 1.05. Quebec is layered, because QST of 9.975% applies to the pre-GST price, giving a combined 14.975%, so divide by 1.14975 to reach the pre-tax amount.
HST in Nova Scotia is 14% in 2026. The province cut it from 15% on 1 April 2025 by lowering its own component from 10% to 9%; the federal 5% GST part was unchanged. Nova Scotia is the only jurisdiction at 14%, so the Atlantic provinces are no longer on one rate. Under the transitional rules, amounts that became payable before 1 April 2025 were still subject to 15%.
A refund grows when every slip and receipt reaches the return, so begin by downloading your slips from CRA My Account and matching them against your own records. Then check the items people miss: medical expenses, tuition and its transfer, child care, eligible moving costs, union and professional dues, charitable receipts, and unused RRSP room or capital loss carry-forwards. Prepare both spouses' returns together so transferable credits land in the right place.
Payroll tax withheld from a Canadian salary depends on your gross pay, your province of employment and the credits you claim on the federal and provincial TD1 forms. Your employer also withholds CPP or QPP contributions and EI premiums, which sit outside income tax. Because the brackets are graduated, a raise increases the withholding rate only on the extra income. Run your own figures through the CRA payroll deductions online calculator for an exact amount.
Two groups escape GST/HST. Zero-rated supplies are taxable at nil: basic groceries, prescription drugs, most medical devices, farm and fishing products, and exports. Exempt supplies carry no tax and give the seller no input tax credit: long-term residential rent, where continuous occupancy is at least one month, most health, dental and child care services, tuition for qualifying courses, and many financial services. Short-term accommodation is taxable, not exempt, so a furnished rental let by the night or the week carries GST/HST. Everything else is taxable at the combined rate for the province where the supply is made.
Most financial services are exempt from GST/HST, so ordinary bank charges such as monthly account fees, interest and transaction charges carry no tax. Administrative and non-financial services a bank sells, such as safety deposit box rental or certain reports, can be taxable. Check the statement, which shows any GST/HST charged. For a business, exempt fees generate no input tax credit, so they are recorded at full cost.
Deductions reduce taxable income; credits reduce the tax calculated on it. The usual deductions are RRSP contributions, child care expenses, union and professional dues, employment expenses your employer certifies, eligible moving expenses, deductible spousal support payments (child support is not deductible), and losses from a business or rental. If the same large deductions repeat each year, Form T1213 asks the CRA to reduce the tax withheld from your pay; the CRA publishes no processing standard for it, so file well before the year it applies to.
Fix the withholding or reserve the cash. An employee can ask payroll to deduct extra tax each pay, and should refile the personal tax credits form when a second job or a changed credit claim has made the old one wrong. Self-employed people pay quarterly instalments and hold back a set share of every invoice. RRSP contributions made before the deadline reduce taxable income. Reviewing last year's balance early in the new year is what prevents the repeat.
Bring every slip issued to you for the year, T4, T5 and T3 among them, plus receipts for deductions and credits such as RRSP contributions, medical expenses, donations, child care and tuition. Add last year's return and notice of assessment, any CRA letters, and the authorisation your preparer needs to see your account. If you have self-employment or rental income, bring income and expense totals with the records behind them. Flag any change in marital status, dependants or residency.
