The T1135 foreign income verification statement applies once specified foreign property passes $100,000 in cost — late-filing penalties start at $25 a day. Because the fee is fixed and budget-friendly, the economics stay predictable whether your file is simple or messy.
A few notes from the files we actually work on, because treaty-based corporate tax return is decided by details that never make it into a brochure.
There is no way around the opening fact, so it may as well come first. 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.
Layer a second constraint on top and the picture sharpens: 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 documentation side matters just as much. 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.
In practice, this is why treaty-based corporate tax return rewards a tax expert rather than a generic preparer: each of these points is a judgement call before it is a keystroke. Nothing slows a file like missing records, so for treaty-based corporate tax return begin with.
When you are ready, the process is straightforward — we agree a fixed fee up front, prepare the work, walk you through it before filing, and you pay once the service is delivered.

An inbound transferee on assignment in Vancouver, British Columbia was filing correctly and still overpaying because of foreign accounts that had passed the $100,000 T1135 threshold three years earlier. Restructuring the position cut $45,000 from the annual bill.
The structure at a snowbird spending winters in Arizona in Windsor, Ontario no longer fitted the business, and winters spent in the United States with the day count kept casually and no residency position documented anywhere showed it. Rebuilding it saves $38,500 a year.
Growth at a family with a Florida vacation property in Saskatoon, Saskatchewan had outrun the back office, and dividends paid to a non-resident shareholder with nothing withheld, leaving the payer holding the liability broke first. Headcount reached 88 with $72,000 of cash freed.
A family transfer at a Canadian with a US employer in Mississauga, Ontario would have been fully taxable because of a shareholder loan balance that would have been picked up as income on closing. Restructuring deferred $630,000.
A Canadian corporation with US customers in Moncton, New Brunswick was profitable and permanently short of cash, with US tax paid but no foreign tax credit claimed on the Canadian return behind the gap. Restructuring the tax cycle freed $96,000.
Collections had begun against a contractor working on both sides of the border in London, Ontario over 3 years of unfiled returns. Bringing them current cut $24,000 from the balance.

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.
Treaty-Based Corporate Tax Return 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.

The honest starting point is this: 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. Everything else we would tell you is tailoring, and tailoring requires seeing your file.
Non-residents earning Canadian rental income face 25% withholding on gross rent unless a section 216 election is filed, which taxes the net instead. We flag this early with every client it touches, because finding it out at filing time leaves you far fewer options than finding it out now.
The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.
Sign in to CRA My Account, or use the CRA's mobile app, where the return shows as received, in process or assessed, and the refund amount and payment date appear once it has been assessed. The CRA also runs an automated telephone service giving the same information. A representative you have authorised through Represent a Client can check it for you. If the status has not moved past the published processing time, the return is probably under review.
CRA online filing for 2025 returns opened on 23 February 2026 and stays open until 29 January 2027. You can prepare a return before the service opens, but it cannot be transmitted, and slips such as T4s and T5s often arrive only in late February. Filing early makes sense if you expect a refund. If you expect a balance owing, you can still file early and pay by 30 April 2026.
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.
Several NETFILE certified programs are free to use for straightforward returns, and the CRA publishes the certified list each filing season. If your income is modest and your return is simple, a free volunteer tax clinic can prepare and file it for you. Some people also receive a CRA invitation to file through a simplified phone or digital service. Free tools cover most employment and pension returns; self-employment, rental or foreign income usually needs more.
Yes. GST/HST you charge customers is collected on the government's behalf, so it sits as a liability until you remit it. Input tax credits on your purchases reduce that balance, and the net amount is what the GST/HST return reports. Record the tax in its own account at the point of sale; treating collected tax as revenue overstates sales and hides what you owe. Reconcile the account every filing period against the return.
As of 2026 the harmonised sales tax is 13% in Ontario and 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island. Nova Scotia has been 14% since 1 April 2025, down from 15%. The other provinces and territories are not harmonised: GST is 5%, with British Columbia PST at 7%, Saskatchewan PST at 6%, Manitoba RST at 7% and Quebec QST at 9.975% on the pre-GST price. Alberta and the territories charge GST only.
Yes. Household paper products are ordinary taxable goods, not basic groceries, so GST or HST applies at the rate where you buy them: 5% GST alone in Alberta and the territories, 13% in Ontario, 14% in Nova Scotia from 1 April 2025, and 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island. British Columbia, Saskatchewan, Manitoba and Quebec charge GST plus their own provincial tax.
Most financial services and most health care services are exempt, including services billed by physicians, dentists and registered nurses, so no GST/HST is charged and the supplier cannot claim input tax credits on the related costs. Legal services are taxable. Royalties are generally taxable when paid for the use of property in a commercial activity. Exempt is not the same as zero-rated, which is taxable at a rate of zero and keeps your credits, so check CRA's lists for your exact supply.
Double taxation is lawful, and relief comes through credits and treaties rather than exemption. A Canadian resident taxed abroad on foreign income normally claims a foreign tax credit, while Canada's tax treaties cap withholding and decide which country taxes first. Inside Canada, corporate profits paid out as dividends carry a gross-up and dividend tax credit so the combined burden approximates a single level of tax. US LLCs are a common trap, since Canada usually treats one as a corporation.
You qualify if you live with an eligible child, are primarily responsible for their care, and are a resident of Canada for tax purposes. You or your spouse or common-law partner must be a citizen, permanent resident, protected person, registered Indian, or a temporary resident meeting the CRA's conditions. The payment is calculated from family net income, so both of you have to file a return every year, even with no income to report.
Take the net income line from your partner's completed return for the same year, or the net income shown on their notice of assessment. Where you hold authorised access, it also appears in CRA My Account. If their return is not finished, prepare both returns together so the figure is settled before either is filed. A reasonable estimate is accepted, but a wrong number usually shows up later as a benefit recalculation.
A treaty exemption is relief given by a tax treaty between Canada and another country so the same income is not taxed twice. Depending on the article relied on, it can remove Canadian tax entirely, cap a withholding rate, or give taxing rights to only one of the two countries. The relief is not automatic: you usually certify your residence to the payer or claim it on a Canadian return, and keep the supporting documents.
