The pattern in sole proprietor tax return files repeats often enough that an accounting firm can usually tell early on where a file will need work. What follows is that read, written down for Sole Proprietor Tax Return.
The foundation is simple to state and easy to trip over: Transferring a proprietorship into a corporation can be done on a tax-deferred basis under section 85. The deferral holds only if the election is filed on time with the correct elected amounts.
A related rule tends to get overlooked precisely because the first one draws all the attention: A partner’s adjusted cost base in the partnership interest is reduced by draws and increased by allocated income. A negative ACB triggers an immediate capital gain. And on timing: Partnership income is allocated to partners according to the partnership agreement, and an allocation the agreement does not support can be reallocated by the CRA.
The practical upshot is simple: every one of these rules has a version that helps you and a version that costs you, and which one applies depends on choices made before filing. That is precisely the ground an accounting firm covers. Think of this list as the raw material an accounting firm works from on sole proprietor tax return.
Whatever the file involves, the terms do not change: fixed fee agreed up front, review together before filing, payment after the service.

15 months of records at an unincorporated trades business in Kelowna, British Columbia had never been reconciled. That left business income reported entirely on one spouse’s return despite shared operations. Rebuilding recovered $10,000.
Nothing reconciled at an unincorporated trades business in Kelowna, British Columbia. Every filing started with 15 months of cleanup. The file was carrying business income reported entirely on one spouse’s return despite shared operations. We rebuilt from source rather than correcting on top of the existing file. We filed the section 85 election with correct elected amounts and rolled the assets in without a taxable disposition. Then we set the routine that keeps it clean. 15 months reconciled to the bank. The close now takes 8 days, and $10,000 of previously unclaimable input tax was recovered in the process.
A joint-venture property partnership in Calgary, Alberta expanded into a second province. The file already carried three partners operating on a handshake, with no written agreement covering allocations or a departure. Every obligation was set up in advance and $55,000 of cash released.
Revenue at a joint-venture property partnership in Calgary, Alberta was up sharply and cash was tighter than ever. Underneath it sat three partners operating on a handshake, with no written agreement covering allocations or a departure. We restructured the draw policy so no partner’s adjusted cost base went negative again, and reported the deemed gain correctly for the year it arose. Every new obligation was set up before it was triggered, not after. That covered registration, remittance frequency and provincial filing. $55,000 of cash was released from the working capital cycle. The expansion completed with every registration and filing obligation covered from day one.
A freelance developer in Ottawa, Ontario was preparing to sell. However, a single shareholder holding every share, with no room to multiply the exemption disqualified the shares. Purification sheltered $735,000 under the exemption.
A freelance developer in Ottawa, Ontario had an offer on the table and 21 months to close. The shares did not qualify for the capital gains exemption. A single shareholder holding every share, with no room to multiply the exemption was part of the reason. We purified the corporation so the shares met the qualifying tests. We split the shared overhead on a documented basis, so each partner’s reported share carried only the expenses that belonged to it. All of it was done well ahead of the closing date. The sale closed on schedule with $735,000 sheltered by the lifetime capital gains exemption across the shareholders.
A partnership with a corporate partner in Halifax, Nova Scotia was carrying $142,000 of penalties and interest. The charges arose from a partnership that crossed the T5013 threshold two years before anyone noticed. A relief application cancelled that amount.
An assessment of $142,000 landed at a partnership with a corporate partner in Halifax, Nova Scotia following a desk review. It turned on a partnership that crossed the T5013 threshold two years before anyone noticed. The auditor had not seen the records behind it. We kept the proprietorship on a December 31 fiscal period and moved the year-end question into the incorporation plan where it could actually be answered. We then set out the legislative basis for the position alongside the documents supporting it. $142,000 of penalties and interest was cancelled under the taxpayer relief provisions, and the underlying assessment was adjusted to match the filed position.
A food-truck sole proprietorship in Brampton, Ontario was profitable and permanently short of cash. Behind the gap sat a partner taxed on an allocation in a year they had drawn nothing at all. Restructuring the tax cycle freed $35,000.
A food-truck sole proprietorship in Brampton, Ontario was profitable on paper and short of cash every month. A partner taxed on an allocation in a year they had drawn nothing at all explained most of the gap. We reconciled each partner’s allocation, capital account and drawings, so what was reported for tax matched the agreement instead of the cash taken. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars. $35,000 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
A proprietor preparing to incorporate in Victoria, British Columbia faced a $140,000 proposed reassessment. It came after partner draws that had pushed one partner’s adjusted cost base negative. We rebuilt the documentation and the adjustment was withdrawn in full.
A proprietor preparing to incorporate in Victoria, British Columbia received a proposal letter opening a review of sole proprietor tax return. The CRA had identified partner draws that had pushed one partner’s adjusted cost base negative. It proposed an adjustment of $140,000, with 30 days to respond. We treated the response as an evidence exercise rather than an argument. We rewrote the partnership allocation to match how the practice actually operated, effective for the following fiscal year. We then indexed every supporting document against the specific line the auditor had questioned. The proposed adjustment was withdrawn in full — all $140,000 of it. The file closed in 4 weeks with no change to the assessed amounts and no penalty.

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.
Sole Proprietor 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 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 sole proprietor tax return services include complete filing, compliance management, and strategic advice customized to Canadian tax laws.

An unincorporated business carried on by an individual has a fiscal period ending December 31 unless the alternative-method election under subsection 249.1(4) is in place. Choosing a year-end the way a corporation can is not available to a proprietor. 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.
There is a widespread assumption here, and the actual position is worth stating plainly. T1 returns are due April 30, and June 15 for the self-employed — but any balance owing is due April 30 regardless, with interest compounding daily from that date. The June deadline misleads a great many self-employed filers into paying two months late without realising it. If your current setup was built on the assumption instead of the rule, that is fixable — but sooner is better than later.
The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.
Yes. Most people file electronically through NETFILE using CRA-certified software, which submits the return directly and confirms receipt immediately. Filing online is also what makes a fast refund possible: for 2025 returns filed in 2026 the CRA service standard is about two weeks online, against a considerably longer standard for a paper return, and registering direct deposit removes the cheque step. CRA online filing for 2025 returns opened 23 February 2026 and closes 29 January 2027.
The route depends on the structure. A sole proprietor or partner reports business income on Form T2125 and files it with the personal T1 return; for the 2025 year the self-employed filing deadline was 15 June 2026, while any balance owing was due 30 April 2026. An incorporated business files a separate T2 corporate return for each fiscal year, due six months after that year end, on top of whatever the owner reports personally.
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.
From its first profitable year: there is no tax-free start-up period. A sole proprietor reports business income on a T2125 with the T1 and pays with the personal return. A corporation files a T2 six months after each fiscal year end, with the balance due two months later, or three months for an eligible small business corporation. GST/HST registration is separate and begins once taxable revenue passes $30,000, and payroll remittances start with the first employee.
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.
Almost always, yes. A lump sum from a registered pension, a commuted value, a deferred profit sharing plan or an unlocked locked-in account is income in the year you receive it, and tax is withheld before you get the money. A direct transfer of an eligible amount into an RRSP or RRIF can defer the tax, but it must move plan to plan rather than through your bank account. Ask for the transfer paperwork before the payout is processed.
Your purchase price does not set your property tax directly, but it becomes part of the sales evidence assessment authorities use to value comparable homes, so paying well above market can pull your assessment up at the next valuation. A private appraisal done for a mortgage or refinancing is not shared with the assessor and changes nothing on its own. The assessed value on your notice, times the municipal rate, is what drives the bill.
File the return on time regardless. The late-filing penalty is charged for filing late, not for paying late, so filing protects you even when you can send nothing with it. Then contact the CRA to set up a payment arrangement based on what you can genuinely afford; interest continues to accrue, but collection action generally holds while you keep to the schedule. Form RC4288 asks for relief from penalties and interest where circumstances beyond your control caused the delay.
Property tax on the home you live in is not deductible and is not refunded on your federal return. It becomes claimable only where the property earns income or supports a business: a landlord deducts it against rental income, and a self-employed person's work-space-in-the-home claim includes a reasonable share. A salaried employee's work-space claim covers rent and utilities but not property tax; only a commission employee may add property tax and home insurance. Some provinces give an income-tested credit tied to rent or property tax paid.
A corporation files its own T2 return and pays tax on its profit. For 2026 a Canadian-controlled private corporation pays the federal small business rate of 9% on the first $500,000 of active business income carried on in Canada and the federal general net rate is 15%, with each province adding its own rate on top. A sole proprietorship or partnership is not taxed separately: the profit goes on the owner's T1 and is taxed at personal rates, with instalments and CPP on that income.
Schedule 5 is where you claim the amounts for a spouse or common-law partner and dependants: the spouse or common-law partner amount, the amount for an eligible dependant, the Canada caregiver amount and amounts for an infirm dependant. For each person you enter the name, relationship, date of birth and net income, and the schedule works out what carries to your return. Tax software builds it from the family details you enter, so the net income figures must be accurate.
