The T1135 foreign income verification statement applies once specified foreign property passes $100,000 in cost — late-filing penalties start at $25 a day. Our canada-us cross-border tax services engagement is priced as a economical flat fee, so the cost is known before the work starts.
Good canada-us cross-border tax services work is mostly about sequencing: which questions to settle before which. These notes lay out the sequence a tax advisor follows on Canada-US Cross-Border Tax Services engagements.
First, the rule that sorts straightforward files from complicated ones: A CCPC files its T2 within six months of year-end, with the balance due two months after (three where the small business deduction is claimed). The 9% federal small business rate applies to the first $500,000 of active business income. The filing and payment deadlines differ, and interest runs from the payment date. Filing on time while paying late still costs money.
That rule rarely travels alone; alongside it sits another: The T1135 foreign income verification statement is required once specified foreign property exceeds $100,000 in cost. Late-filing penalties start at $25 a day to a maximum of $2,500 per year, before gross-negligence penalties. The final point is less about opportunity and more about what happens when a file is challenged: A US LLC is a flow-through for US purposes but a corporation for Canadian purposes, and that mismatch routinely produces double taxation unless the structure is corrected.
The common thread in these rules is that they punish assumptions and reward verification. Engaging a tax advisor for canada-us cross-border tax services is, at bottom, a way of replacing assumptions with checked answers. Every canada-us cross-border tax services file rests on documentation, so start by collecting.

Remittances at a Canadian corporation with US customers in Saskatoon, Saskatchewan were chronically late because of foreign accounts that had passed the $100,000 T1135 threshold three years earlier. Fixing the schedule refunded $42,000.
3 years of filings at a non-resident owning Canadian rental property in Burnaby, British Columbia had never claimed the incentives the work qualified for. The review recovered $130,000.
An emigrant who left Canada mid-year in Regina, Saskatchewan was preparing to sell, but no valuation on file to support the price the parties had agreed disqualified the shares. Purification sheltered $585,000 under the exemption.
An inbound transferee on assignment in Red Deer, Alberta was 5 weeks from a deadline while carrying a departure year filed as a normal resident return with no deemed disposition reported. Filing complete and on time avoided roughly $105,000 in penalties.
A Canadian corporation operating a US branch in Windsor, Ontario expanded into a second province carrying US tax paid but no foreign tax credit claimed on the Canadian return. Every obligation was set up in advance and $94,000 of cash released.
A $131,000 reassessment was proposed against a family with a Florida vacation property in Barrie, Ontario following invoices paid to a non-resident consultant working on site in Canada with no Regulation 105 withholding taken. The documented response reduced it to nil.

Direct answers to what Canadian business owners actually ask before hiring an accountant.
Canada-US Cross-Border Tax Services 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 are a cloud-based practice serving every province and territory, 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.

Let us give you the substance first and the caveats second. The rate charged follows the customer's province, not the seller's: 13% into Ontario, 15% into New Brunswick, Newfoundland and Labrador and PEI, 14% into Nova Scotia (since 1 April 2025), 5% plus provincial tax elsewhere. A seller charging its own province's rate nationally is under-collecting on some sales and over-collecting on others, and owes the difference on the under-collected ones. The caveat is simply that facts on your file can shift the outcome, so treat this as the baseline rather than the final word.
A tax practitioner answers this differently than a search engine, because the rule has edges. A CCPC files its T2 within six months of year-end, with the balance due two months after (three where the small business deduction is claimed). The 9% federal small business rate applies to the first $500,000 of active business income. The filing and payment deadlines differ, and interest runs from the payment date. Filing on time while paying late still costs money. Where your business sits relative to those edges is what we establish in the first meeting.
The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.
File a T1 return for the year, sending it electronically with CRA-certified software or mailing a paper return. Gather your slips and receipts first and check them against the ones listed in My Account. For the 2025 tax year the filing and payment deadline was 30 April 2026, or 15 June 2026 to file if you or your spouse were self-employed, with payment still due 30 April 2026. CRA online filing for 2025 returns closes 29 January 2027.
Canadian income tax is built up in layers. You total your income for the year, subtract the deductions you qualify for to arrive at taxable income, then apply the federal brackets and your province's brackets to that figure. Each bracket rate applies only to the income sitting inside it, so earning more never retaxes the dollars below. Non-refundable credits, starting with the basic personal amount, come off the tax afterwards. Look up the CRA bracket table for the tax year you are filing.
A refund is the tax already paid minus the tax actually owed. Add the income tax withheld on your slips to any instalments you paid, work out tax payable on your total income after deductions and credits, and the difference comes back if the first figure is larger. Large refunds usually trace to over-withholding on employment income, RRSP contributions, or credits transferred to you. Run the numbers through the CRA's or a commercial estimator before you file.
Canada taxes income in graduated brackets, so only the income above a threshold is taxed at that bracket's higher rate and moving up a bracket never reprices the income below it. There is one federal set of brackets and a separate set for each province and territory, and the thresholds are indexed to inflation every year. Look up the current figures for your province on the CRA rate tables rather than relying on an older list.
Multiply the pre-tax price by the rate for the province of supply. On a $100 purchase in 2026 that is $13.00 in Ontario (13%), $14.00 in Nova Scotia (14%), and $15.00 in New Brunswick, Newfoundland and Labrador or Prince Edward Island (15%). In the non-participating provinces and the three territories only the 5% GST applies, so $5.00, plus any provincial sales tax billed separately.
Multiply the pre-tax price by the rate that applies where the sale happens. In Ontario that is 13% HST for 2026; in Alberta 5% GST; in British Columbia 5% GST plus 7% PST, each applied to the same base. Quebec is the exception, where 9.975% QST is charged on the pre-GST price, giving 14.975% combined. To back the tax out of a tax-included price, divide by one plus the rate.
Order it from the forms and publications pages at canada.ca, or by calling the individual enquiries line, and say which tax year and which province you need, because the package carries that province's schedules. The CRA also mails a package automatically to people who filed on paper the year before. Paper returns take considerably longer to assess than electronic ones. Online filing for the 2025 tax year opened 23 February 2026 and closes 29 January 2027.
For a return filed online the CRA usually issues the refund in about two weeks. A non-resident return can take up to sixteen weeks. Timing slips if the CRA reviews a claim and asks for receipts, if the return is filed on paper, or if the refund is applied against an existing balance or a debt to another government program. Setting up direct deposit in CRA My Account is the fastest way to receive it.
It refers to the spouse or common-law partner amount, a non-refundable credit for supporting a spouse whose own net income for the year was low. The credit shrinks as their net income rises and disappears once it passes the threshold, and only one partner can claim it. Your employer's personal tax credits form asks the same question, so tax withheld at source can be reduced. Claim it on the supporting partner's return and enter the spouse's net income accurately, since the credit is calculated from it.
Both sides do. The employee pays income tax, CPP contributions and EI premiums, all withheld from each pay and remitted by the employer. The employer pays its own share on top: for 2026, CPP of 5.95% matching the employee's up to the $74,600 ceiling with a $3,500 basic exemption, plus EI at 1.4 times the employee's rate of $1.63 per $100 of insurable earnings. The employer remits everything and reports it on a T4.
Rent on your own home is not deductible on a federal return, so most tenants have nothing to claim and no receipt to attach. Keep them anyway in two cases. Some provinces run a credit or benefit that takes rent paid into account, claimed on that province's schedule with the return. And if you are self-employed or work from home under the conditions the CRA sets, part of the rent can support a workspace claim. Receipts are what the CRA asks for if a claim is reviewed.
The CRA charges compound daily interest on an unpaid balance starting the day after the payment deadline, at the prescribed arrears rate it sets each quarter. Because that rate is reset quarterly, check the current figure on the CRA site rather than relying on one you saw last year. The same interest applies to late instalments and to penalties already charged. Paying part of the balance now reduces the interest accruing on the rest.
