Manitoba corporate tax: 9% in total on the first $500,000 of profit

Summary

If your corporation has a place of business in Manitoba, its profit is taxed by two governments: the federal government and Manitoba. Both tax the corporation itself. Money you take out later as salary or dividends is taxed again in your own hands, and that isn’t covered here.

For the 2026 tax year Manitoba charges 0% on the first $500,000 of active business income, and 12% on everything above that ceiling.¹ Active business income means profit from running a business rather than profit earned on investments, and both governments call the ceiling the business limit. If you control more than one company, that $500,000 is shared between them rather than given to each. The federal government charges 9% on the same first $500,000 and 15% above it,² so a Manitoba corporation pays 9% inside the limit and 27% above it.³ Every dollar of that 9% is federal, because Manitoba’s share inside the limit is nothing.

Three things follow, and we’d work through them in this order:

1. Manitoba writes its own corporate tax law, but the Canada Revenue Agency (the CRA) assesses and collects the provincial tax on your corporation’s income tax return, the T2. There’s one return rather than two.⁴
2. The 0% isn’t automatic. Manitoba allows it only to a corporation that also claimed the federal small business deduction for the same year. Anything that ends the federal claim ends Manitoba’s zero in the same return, at a cost of up to $90,000 of extra corporate tax in one year.⁵
3. Retail sales tax, at 7% and entirely separate from the 5% federal goods and services tax, is where the provincial compliance work sits.⁶

We’d usually tell a Manitoba owner whose profit is comfortably under $500,000 to treat the provincial income tax layer as finished, and spend the effort on the sales tax side instead. That flips as profit nears $500,000, or as the investment income of your corporation and the companies connected with it nears $50,000 a year, which is where the limit starts to disappear.

One return, and what puts a corporation in Manitoba

In Manitoba Finance’s own words, Manitoba’s corporation income taxes are administered and collected by the CRA on the province’s behalf.⁴ For corporate income tax that means no provincial return, no provincial account and no provincial deadline. Your accountant or T2 software works the tax out on a CRA worksheet called Schedule 383, which stays in your records rather than being filed. The result is carried to line 230 of Schedule 5, the schedule of the T2 that reports provincial tax.⁴ The retail sales tax below is the opposite on all three counts.

Manitoba’s corporate income tax reaches a corporation only where it has a permanent establishment in the province, which is generally a fixed place the business operates from (e.g. an office, a workshop, a warehouse or a factory), and in some cases an employee or agent based in Manitoba with general authority to sign contracts for it. Where you incorporated doesn’t decide it, and neither does where your customers live.⁷

Manitoba’s rates for 2026, and the condition attached to the zero

Every province publishes two corporate income tax rates. A lower rate applies to active business income up to the business limit, the same $500,000 as above, and a general rate applies to everything over it. Manitoba’s lower rate for 2026 is 0%, its general rate is 12%, and its business limit is $500,000.¹ The province eliminated its small business income tax with effect from December 1, 2010, and Budget 2026 changed neither rate when it was presented on March 24, 2026.¹

Federal 9% plus Manitoba 0% is 9% in total inside the limit, and federal 15% plus Manitoba 12% is 27% above it.³ On a full $500,000 of profit inside the limit the tax comes to $45,000, every dollar of it federal. Nil is as low as a provincial lower rate goes, and Manitoba is the only province there on the CRA’s rate table, with Yukon the only territory. As such 9% is the lowest combined small business rate in Canada.⁸

The province doesn’t legislate a rate of nil, which matters more than it sounds. Manitoba’s own Income Tax Act charges 12% on the profit allocated to the province, then allows a credit equal to 12% of the profit that falls inside the $500,000 limit. On that profit the 12% charged and the 12% credited cancel exactly, so the provincial tax is nil. The condition attached is that a corporation gets the Manitoba credit only where it also claimed the federal small business deduction for the same year, under section 125 of the federal Income Tax Act.⁹ That federal deduction is a separate one, sitting in a separate law that happens to share a title. The federal 9% isn’t automatic either, and a corporation gets it by claiming that federal deduction on its T2 each year. So when the federal claim fails, Manitoba’s zero fails with it in the same return, with no provincial form to file and no provincial decision to object to.

Investment income, and how the zero goes

If you own or control more than one company, the tax rules treat them as a single group and call the members associated corporations. Investment income earned anywhere in that group is the usual way an owner loses the federal claim. Where the group together earns more than $50,000 in a year of what the rules call adjusted aggregate investment income (e.g. interest, rent, dividends on portfolio shares and the taxable half of a capital gain, meaning what the companies earn from money and property rather than from operating), the $500,000 business limit shrinks by $5 for every $1 of that income above $50,000. At $100,000 half the limit is gone, and at $150,000 all of it is.¹⁰ Losing the whole limit costs a Manitoba corporation up to $90,000 of extra corporate tax in a year, being the 18-point gap between 9% and 27% applied to $500,000 of profit.⁵

Retail sales tax

Manitoba charges a 7% retail sales tax of its own on top of the 5% federal goods and services tax.⁶ They’re separate taxes, with separate registrations, separate returns and separate auditors behind them. Manitoba runs its own through an online system called TAXcess and charges the 7% on the price before the federal tax goes on, so a $100 sale carries $7 provincially and $5 federally.⁶

The difference that costs owners real money is that retail sales tax has no equivalent of the input tax credit that lets a business recover the federal 5% it pays on its own purchases. Manitoba’s 7% on your own overheads is a permanent cost unless an exemption applies (e.g. goods bought for resale, claimed by quoting your Manitoba retail sales tax number, which is not your GST number, at the time of purchase).

Three points cover most of what an owner-managed corporation needs here:

• What’s taxable. Most goods, a defined list of services (e.g. accounting, architectural, legal, engineering, security and private investigation work), and, since January 1, 2026, cloud computing, which Manitoba added to that list and defines to cover software subscriptions, data storage and remote processing.¹¹ You pay the 7% when you buy any of these and charge it when you sell one.
• Registration. Anyone carrying on business in Manitoba needs a retail sales tax number before making a taxable sale. A business whose taxable sales in Manitoba are under $30,000 in a year may skip registering, but that exception is narrower than it reads. The exception isn’t open to a business buying from out-of-province suppliers who don’t collect Manitoba tax, or to one selling tobacco or liquor, so ordering online from an untaxed supplier is enough to lose it. If you do rely on it, your invoices have to say the tax is included in the price and must not show it separately. Once your Manitoba taxable sales pass $30,000 you have one month to register and start charging.¹²
• Purchases from outside Manitoba. Where the goods your business brings in from outside the province total $800 or more in a month, in two or more months of the same calendar year, you have to register and work out the 7% on those purchases yourself.¹²

How often you file depends on how much tax you collect: monthly where that averages $5,000 a month or more, quarterly between $500 and $4,999, and annually below $500. Returns and payment are due by 4

p.m. on the 20th of the month after the period they cover, moving to the next working day if the 20th is a weekend or a statutory holiday.¹²

How often this changes

Manitoba presents its budget in March or April, and that’s the event that moves the corporate rates. Budget 2026 moved neither of them, so we’d re-check the two rates and the $500,000 limit each spring, and sooner if profit or the group’s investment income is heading for its threshold.

Retail sales tax moves more often, and one change has been announced and is not yet in force. From January 1, 2028, every business registered to collect retail sales tax will have to file its returns and send in the tax electronically through TAXcess.¹³ Monthly filers already have to, so the change lands on quarterly and annual filers, who can still file on paper until then.

Closing thoughts

There’s an oddity in Manitoba worth sitting with: the province asks a good deal more of your attention than of your money. While profit stays inside the limit, nothing on the corporate income tax side needs managing at all. The sales tax side wants a registration, a filing rhythm, a rule about what your invoices may say, and a habit of checking what you bought from elsewhere. We’d rather an owner’s attention went where the mistakes happen than where the rate is highest, and in Manitoba the mistakes are on the sales tax side.

How we handle it

We prepare the T2 with Manitoba’s tax riding on it as one job, and check the small business deduction claim and the group’s investment income before your year-end rather than after. Where a client sells taxable goods or one of the taxed services, we set up the retail sales tax registration and run those returns alongside the federal ones. Fees are fixed for the year and agreed before any work starts.

7. Permanent establishment is defined in the Income Tax Regulations (C.R.C., c. 945) at s. 400(2) as a fixed place of business, the definition naming an office, a branch, a mine, an oil well, a farm, timberland, a factory, a workshop or a warehouse. Paragraph 400(2)(b) also deems an establishment wherever an employee or agent has general authority to contract for the corporation, or holds a stock of the employer’s merchandise from which orders are regularly filled. Paragraph 400(2)(e.1) deems a corporation that would otherwise have no permanent establishment anywhere to have one at its registered office, which is the narrow case in which the province of incorporation does decide the question.

8. The CRA’s “Corporation tax rates” table lists Manitoba’s lower rate as nil and Yukon’s as 0%, each with a $500,000 business limit, and lists no other province or territory at nil. That table expressly excludes Quebec and Alberta, neither of which has a corporation tax collection agreement with the CRA. Alberta’s 2% lower rate is taken from this site’s provincial rate dataset, which carries the Government of Alberta’s own citation. Quebec’s lower rate is 3.2% for 2026, rising to 2.2% for taxation years beginning after April 29, 2026, and is stated in full with its Quebec issuer sources on /guides/quebec-corporate-tax/, which owns it. With the federal 9% on top that is 12.2% or 11.2%, both above Manitoba’s 9%. Table read 2026-08-24. ↩

9. The Income Tax Act (Manitoba), C.C.S.M. c. I10, sets both the corporate tax rate and the small business deduction rate at 12% for any period after November 30, 2010, at s. 7(3). The deduction itself is at s. 7(2), which opens by requiring that the corporation claim a small business deduction for the taxation year under section 125 of the federal Act. The business limit is set at $500,000 for calendar years after 2018 at s. 7(3.1). Sourced to the Manitoba Laws consolidation, current to August 20, 2026, and verified 2026-08-23. ↩

10. Manitoba Finance’s page “Corporate Income Taxes” states that Manitoba parallels the federal measure phasing out the $500,000 small business limit for corporations earning between $50,000 and $150,000 of passive investment income in a taxation year, for tax years beginning after 2018. The $5-for-$1 reduction rate is the federal formula.

The same list carries cloud computing in the forms of software as a service, platform as a service and infrastructure as a service, and refers to Bulletin RST 033 for detail. Cloud computing was added on January 1, 2026, a change announced in Information Bulletin 125, “Taxation Changes - Budget 2025”. Packaged and prewritten software was already taxable before that date under RST 033, and custom software remains exempt, so the 2026 change widened the base rather than creating it. ↩

12. Information Bulletin RST 004, “Information for Vendors” (revised June 2024), from Manitoba Finance, Taxation Division, read in full on 2026-08-24. A retail sales tax number is required before making any taxable sale, with an exception for annual taxable sales under $30,000. The bulletin withdraws that exception from businesses using out-of-province suppliers who do not collect Manitoba tax, from businesses selling tobacco or liquor products, and from out-of-province businesses that have not paid Manitoba tax on goods and services purchased for resale in Manitoba, and states that a business not eligible for the exception must register. A business relying on the exception must state on its invoices that tax is included in the price, and must not itemise it. A business that crosses $30,000 has one month to register and put collection in place. Returns are monthly where average tax collectable is $5,000 or more a month, quarterly between $500 and $4,999, and annual below $500, and are due with payment by 4

    p.m. on the 20th day of the month following the reporting period, moving to the next working day where the 20th falls on a weekend or statutory holiday. The same bulletin requires a vendor carrying on business in Manitoba who brings in tangible personal property purchased outside the province with a fair value of $800 or more, in each of two or more months in a calendar year, to register and self-assess the tax on those purchases. ↩ ↩² ↩³
