Updated Checked by the Tax-Services.ca editorial team How we check
Bookkeeping requirements in Manitoba are built around one tax the other Prairie provinces treat differently: the 7% retail sales tax, or RST. You charge it on the selling price before GST, which adds another 5%, and you keep your books for the current year plus six years.
How does Manitoba’s retail sales tax work?
The province applies RST to the retail sale or rental of most goods and certain services. Manitoba’s own retail sales tax page says the tax is calculated on the selling price, before the GST is applied, so the two taxes don’t stack on each other. On a $1,000 sale our GST and PST calculator shows $50 GST and $70 RST, for $1,120. That’s a 12% combined rate.
Try a smaller one. A shop in Brandon sells a $250 item. The RST is $17.50, the GST is $12.50, and the customer pays $280. Two tax lines on the invoice, two accounts in your books.
The calculator labels the provincial line as RST for Manitoba, but the tool treats every sale as fully taxable. Real life has exemptions, and you should check yours in the province’s bulletins before you set up tax codes. We didn’t verify how each product is treated.
What records does a Manitoba vendor have to keep?
Manitoba Finance has a bulletin, RST 016, on record keeping. As we read it, books of account, records and documents from the current fiscal year plus the six years before it must not be destroyed, and general ledgers are kept without an end date. Anything tied to tax that’s outstanding or in dispute stays too. The bulletin was a scanned file that our tools read only in part, so open it yourself before you set a shredding schedule.
| Item | Manitoba or federal rule | Who sets it |
|---|---|---|
| RST rate | 7% of the selling price, before GST | Manitoba Finance |
| GST rate | 5% | CRA |
| RST records | Current year plus six years (bulletin RST 016, read in part) | Manitoba Finance |
| Federal records | Six years from the end of the last tax year they cover | CRA |
| Storage | At your business or home in Canada unless the CRA agrees otherwise | CRA |
The federal wording comes from the CRA’s page on where to keep your records and for how long. Two sets of rules means the longer one wins in practice. If you aren’t sure which applies to a given file, keep it for the longer period.
Do I have to register for RST?
Businesses that sell taxable goods or services in Manitoba generally register as vendors with the province, and Manitoba runs its taxes through the Manitoba Tax Administration Portal (MTAP). We couldn’t read the exact registration rules, including any thresholds, so treat this as a pointer and check the vendor information bulletin on the province’s site. Registering for GST with the CRA is a separate step. Doing one doesn’t register you for the other.
What does a small Manitoba corporation pay?
Suppose a Canadian-controlled private corporation earns $400,000 of active business income with no associated companies. Our corporate tax calculator shows $36,000 federal tax and nothing provincial, so 9% combined. Nothing provincial? That’s what the tool assumes, using a 0% provincial small business rate we couldn’t fully confirm from provincial pages.
Push the income to $900,000 and the total becomes $153,000, or 17%, because the part above $500,000 is taxed at the general rates. The calculator skips passive income rules, associated companies and credits. For wages, the payroll deductions calculator is the place to start.
Where do bookkeepers usually go wrong in Manitoba?
They apply RST to the wrong base. It’s on the price before GST, so charging 7% on a GST-included total overstates the tax and your customer notices. On a $1,000 sale that mistake gives $73.50 instead of $70. A few bucks over per sale doesn’t sound like much until it’s a thousand sales. Use two lines and two accounts.
A second problem is moving to Manitoba from a province where you never charged a provincial tax, then keeping the old habits. A third is letting the general ledger slide. If a bulletin says it’s kept indefinitely, back it up.
Some old summaries send Manitoba businesses to the securities commission for bookkeeping. That’s for offering shares to the public, and it has nothing to do with everyday records for a small firm, so ignore it.
What should a monthly routine look like?
Keep it dull and repeatable. Reconcile the bank account, match every sale to an invoice that shows RST and GST on separate lines, and park the tax you collected in its own account until the return is due. At year end, make sure the ledger and a copy of the files are backed up somewhere other than the office computer. A boring routine beats a heroic clean-up in March.
Our sources
The RST rate and its base are from the Manitoba Finance retail sales tax page. Record wording comes from bulletin RST 016, which we could read only in part, and the CRA supplies the federal retention and storage rules. Calculator figures come from our 2026 data files, and some provincial corporate rates are flagged for review. No government body has reviewed or endorsed what you read here.
Frequently asked questions
What is the sales tax rate in Manitoba?
RST is 7% of the selling price, and GST of 5% is added separately, so 12% in all on a fully taxable sale.
Is RST charged on top of GST?
No. RST is figured on the selling price before GST, so the two are calculated side by side.
How long must Manitoba businesses keep records?
Bulletin RST 016 points to the current fiscal year plus six years for RST records, and the CRA uses six years from the end of the last tax year. Check both.
Where do I register for RST?
Through Manitoba Finance, which runs taxes through its online portal, MTAP. Confirm the steps on the province's vendor bulletin.
Do I file with the Manitoba securities commission for bookkeeping?
No. That regulator covers securities offerings, not everyday business records.
