What Is TAXcess? Manitoba's Online Business Tax Portal

Updated November 12, 2026 · Checked by the Tax-Services.ca editorial team · How we check

What is TAXcess, and who runs it?

TAXcess is the secure online service of Manitoba Finance. Businesses use it to apply for tax accounts, file returns, pay and view their Manitoba tax accounts, and individuals use it to apply for the Primary Caregiver Tax Credit. The Manitoba government describes it as simple, secure and available 24 hours a day, seven days a week. You reach it from the Manitoba Finance taxation page through manitoba.ca/TAXcess, and the portal itself sits at taxcess.gov.mb.ca.

The public front page of the portal, which we opened without signing in, offers four things: business registration (apply for new tax accounts, or add access to an existing account), two public registry look-ups (retail sales tax and tobacco tax), the Primary Caregiver Tax Credit for individuals, and a resources block with the TAXcess FAQs, the Taxation Division home page and contact details.

Think of it as the counter where a Manitoba business meets the provincial tax office, open at 2 a.m. on a Sunday if that is when you finally sit down with the books. The service belongs to Manitoba Finance, and this website is independent: we have no link with the Manitoba government and cannot register, file or pay anything for you. Personal income tax and the GST stay with the Canada Revenue Agency.

The vocabulary can throw you if you have only dealt with the CRA. Manitoba calls its provincial sales tax the retail sales tax, or RST, though almost everyone says PST. It is 7 per cent, it is figured on the price before GST, and the GST goes to Ottawa on a separate line. Our guide to the Manitoba PST rate and total tax walks through that arithmetic on a real price.

Which Manitoba taxes can you file in TAXcess?

The official TAXcess FAQs say you can file all provincial business taxes in the portal: retail sales tax (RST), the health and education levy (HE levy), fuel tax, tobacco tax, the International Fuel Tax Agreement (IFTA), insurance corporations tax and corporations capital tax. The Manitoba taxation page adds mining tax and the emissions tax on coal and petroleum coke to the list of taxes Manitoba Finance administers.

The January 2026 brochure "Do I Need to Register?" explains who must register for the four taxes most businesses meet.

Tax	Who pays or collects it	Who must register (official wording, shortened)
Retail sales tax (RST), 7%	Vendors collect it from buyers	Businesses selling taxable goods or services at retail, manufacturers, wholesalers and importers, out-of-province sellers who solicit Manitoba sales, certain contractors, and temporary or intermittent retailers
Health and post secondary education levy	Employers, on pay to Manitoba employees	Employers whose total annual Manitoba remuneration is more than $2.5 million
Tobacco tax	Built into the retail price	Every business that sells tobacco products in Manitoba, wholesale or retail, with a licence for each location
Fuel tax	Built into the retail price	Businesses that sell marked fuel, and any business selling the listed fuels at wholesale, with a licence under the Act

Tobacco retailers must also register for retail sales tax, because RST applies to the full retail price of tobacco products. Fuel dealers that only sell clear, tax-included fuel at retail do not need a fuel tax licence.

Federal taxes stay federal. Personal and corporate income tax and the GST are administered by the CRA, so a Manitoba corner store has two tax relationships: GST through the CRA and RST through TAXcess.

Do you need a TAXcess account? Work through these questions

Most confusion about TAXcess is really confusion about registration, so start there. The official Information Bulletin RST 004, Information for Vendors (revised June 2024) sets out the rules.

You sell taxable goods or services in Manitoba

Any person carrying on business in Manitoba must hold a valid RST number before making taxable sales, with one exception below. A retail sale is a sale to someone who will use the goods or services, as opposed to a registered vendor who will resell them. Bulletin RST 030 summarises what is taxable and exempt, and since July 1, 2026 the grocery exemption is wider.

The $30,000 small business exception

A business with annual taxable sales under $30,000 does not have to register or collect RST. It pays RST on its own purchases, does not charge customers, and must say on the invoice that RST is included in the price, without itemising it. The exception does not apply to businesses that buy from suppliers that do not collect Manitoba tax, or that sell tobacco or liquor products. The official FAQs add that the threshold does not apply to taxable cannabis sales either. When sales pass $30,000, the bulletin gives you one month to register and set up collection.

You are outside Manitoba but sell into it

An out-of-province business must register and collect if it sells taxable goods to Manitoba buyers who will use them in the province and the seller delivers the goods in Manitoba, solicits and accepts orders from Manitoba, or holds inventory there. The order can arrive by phone, internet, e-mail, fax or letter.

You bring goods in from outside the province

Vendors carrying on business in Manitoba who bring in property bought outside the province worth $800 or more, in each of two or more months of the same calendar year, must register and self-assess RST on those purchases. See Bulletin RST 014.

You employ people

Employers paying more than $2.5 million a year in Manitoba remuneration must register for the HE levy. According to the brochure, the levy is 4.3 per cent on the amount above $2.5 million for employers between $2.5 million and $5 million, and 2.15 per cent on the total amount once remuneration passes $5 million. The exemption is shared with associated corporations and prorated for a partial year.

If none of this settles it, the bulletin's advice is to contact Manitoba Finance. The numbers are in the help section below.

How to register and sign up, step by step

Registration is free. The brochure and the vendors bulletin both say there is no charge for a tax account. The sequence below comes from the official TAXcess FAQs, and it works in an order that surprises many first-timers: you create your online login first, and apply for the tax account after you sign in.

1. Open the portal from manitoba.ca/TAXcess and choose "Sign Up" under "New to TAXcess?".
2. Create a unique user ID and password. The FAQs say your username cannot be changed later, so pick one you will keep.
3. Sign in and apply. Under the Access Management tab, choose "Apply for New Tax Account(s)" and complete the application.
4. Wait for approval. Once approved, Manitoba Finance e-mails you a registration package.
5. Find your licence. After you sign in, your Registration/Dealer Licence appears under the Letters tab. From there you can view, file and pay your tax accounts online.

If you already have a tax account

Create the online login the same way, sign in, and choose "Add Access to Existing Tax Account(s)" under Access Management. To verify you, TAXcess asks for your 15-digit account number (it looks like 123456789MT0001) and information from the most recently filed return for each account. If you have not filed a return yet, enter 0. For an IFTA account, enter the 9-digit IFTA number.

Business numbers and corporations

A business number (BN) is a 9-digit number assigned by the CRA (the CRA explains how to get one). The FAQs say each account number is linked to one business number, so if you have more than one BN you need a separate TAXcess login for each. Most legal entities can apply online without a BN, but corporations cannot: a corporation must have its BN first. A business with a U.S. address enters the 5-digit ZIP followed by -0000.

Use a current browser with cookies and JavaScript turned on. The portal says cookies are required and JavaScript must be enabled, and with cookies blocked we saw only a one-line warning. And reach the portal through manitoba.ca/TAXcess or the Manitoba Finance page, not through a search advertisement. The official address is taxcess.gov.mb.ca; anything else asking for your tax account details deserves suspicion.

RST number, account number and BN: which goes where?

Three different numbers show up, and the vendors bulletin separates them. Your RST number is a 7-digit number you receive when you register as a vendor. You give it to suppliers to buy goods for resale without paying RST. Your account number is the 15-digit number on your return and Manitoba Finance letters, with the BN as its first nine digits. You cannot use it to buy for resale tax-free.

	RST number	Account number
Length	7 digits	15 digits, such as 123456789MT0001
What you use it for	Buying for resale or other exempt purposes without paying RST	Signing up for access, filing, paying through your bank, quoting on correspondence
What it cannot do	Let you buy taxable goods for your own use tax-free	Let you buy for resale tax-free

An RST number is non-transferable, so a buyer of your business does not inherit yours. Tell Manitoba Finance right away when the name or address changes, when the business is sold or its legal form changes, and when it closes.

Signing in, two-step verification and account help

The official FAQs answer the questions that come up most, and the answers are short.

• Forgot your username? Click "Forgot Username" on the sign-in page, enter the e-mail address on your account, and the username is e-mailed to you.
• Forgot your password, or locked out? Click "Forgot Password", answer your security question and create a new password. The same route works after a lockout.
• Two-step verification. Choose "Trust this device" on the verification page and you will sign in with only your password next time on that device. Clearing your browser cache or cookies removes the setting.
• Change your e-mail. Under "Manage My Profile", choose "Change Email". You must verify the new address before the change takes effect.
• Change a business address. This cannot be done inside TAXcess. Send a message from your account (More, then Send a Message) or e-mail [email protected] with your account number or BN.
• Send documents. The same message tool lets you send messages and upload supporting documents.
• Give a colleague access. They create their own login, then choose "Add Access to an Existing Account" and verify with the 15-digit account number and return details. To discuss the account with Manitoba Finance, that person must also be authorised, and an Authorization form must be submitted first.
• Close your login. "Manage My Profile", then "Delete My Profile". This does not close the tax account. If you stopped operating, you must complete the termination form.

The department says the portal uses SSL to protect what you send and view, and that your password and secret answer are protected so that even TAXcess administrators cannot read them.

How often do you file, and when is it due?

Filing frequency depends on the average RST you collect per month. The thresholds come straight from the vendors bulletin.

Average RST collectable per month	You file	Rough taxable sales per month at 7%
$5,000 or more	Monthly	About $71,400 or more
$500 to $4,999	Quarterly	About $7,100 to $71,300
Less than $500	Annually	Under about $7,100

The third column is our arithmetic, dividing the tax by 0.07. Manitoba Finance decides your actual frequency.

Returns and payments are due by 4:30 p.m. on the 20th day of the month after the reporting period, or the next working day if the 20th falls on a weekend or statutory holiday. A monthly return covers the previous month, a quarterly return the previous three months, and the annual return the calendar year, due January 20. On a 2027 calendar, with the weekend rule applied:

Return	Covers	Due
Annual	January to December 2026	Wednesday, January 20, 2027
Monthly	January 2027	Monday, February 22, 2027
Monthly	February 2027	Monday, March 22, 2027
Quarterly	January to March 2027	Tuesday, April 20, 2027
Quarterly	April to June 2027	Tuesday, July 20, 2027
Quarterly	July to September 2027	Wednesday, October 20, 2027
Quarterly	October to December 2027	Thursday, January 20, 2028

Statutory holidays can push a date further, so confirm anything close to the line. The deadline is receipt, not mailing: the bulletin says a postmark is not accepted as the date of receipt. Online filers, and TAXcess users with online access to their RST account, get an e-mail reminder about ten days before the return is due. If it never comes, you still owe the return, and you should phone the Tax Information Branch if you have heard nothing by the 10th.

Filing an RST return in TAXcess, screen by screen

The FAQs give the exact path. Sign in, and on the Summary page find your Retail Sales Tax account and select "View Returns" (or open it from your favourites). Then:

1. On the View Returns page, select "File Now" for the filing period.
2. Line 1, Tax Collectable on Sales: enter the RST you collected in the period.
3. Line 2, Tax Owing on Purchases: enter the tax due on the fair value of taxable goods or services brought into Manitoba, taken from stock, or bought in Manitoba for your own consumption without tax being paid.
4. Select "Next". Any outstanding balance is pre-populated and the total due is calculated automatically.
5. Review the return. "Previous" lets you change it, and "print" gives you a copy.
6. Select "Submit".

Nothing to report still means a return. Enter 0.00, since a missing return is still a missing return. When you file online you receive a transaction confirmation number, so save it with the month's paperwork.

Fixing a mistake

You can amend a return filed within the past two years. Choose "More", then "Search Submissions", select the return and click "Continue Editing". An overpayment appears as a credit on your account, which you can use on a later return or claim as a refund. An underpayment attracts penalty and interest. A submitted return can be deleted until it has been processed, which usually takes one to two business days. A saved draft needs "Continue Editing" clicked before you can change anything.

Credits for tax paid in error and bad debts

If you paid RST in error on an exempt purchase and cannot get a credit from the seller, reduce the tax collected on line 1 of a later return, or file a refund claim, within two years. With $400 of RST collectable and $100 paid in error, report $300. For bad debts, the FAQs give this example: a $5,000 item with $250 GST and $350 RST totals $5,600. The vendor remits the $350 but collects only $4,000 and writes off $1,600. The credit is $1,600 divided by $5,600, times $350, which is $100. If the customer later pays, repay the credit on the next return.

How to pay what you owe

Payments are separate from filing, and the FAQs describe the options in detail.

• Pre-authorized debit (PAD) in TAXcess. You need a Canadian bank account. Add a PAD payment source from the More menu, using the banking details on a void cheque or a PAD form from your online banking. A PAD payment made on the due date is processed that day, and a full payment on the due date means no penalty or interest.
• Pay later. You do not have to pay when you file, but the money must arrive by the due date. Choose "Pay Later" when filing, then "Make a Payment" from the Summary page. A PAD payment can be scheduled up to 173 days ahead. If you tick "PAD Payment" while filing, the payment is processed the day you file.
• Your bank's bill payment. Add a payee called "Manitoba Retail Sales Tax" (some banks use "Manitoba RST" or "Minister of Finance MB RST"), or "Manitoba HE Levy" for the levy, and enter your 15-digit account number. Filing is still separate.
• Cheque, money order or in person. Cheques are payable to the Minister of Finance Manitoba. The office takes cash or debit and gives you a receipt.

A PAD payment made in error can be deleted from "Search Submissions" if it has not been processed, though deleting a payment you chose while filing also deletes the return, so resubmit it. Your payment history sits under "Manage Payments and Returns". If a payment or cheque is rejected, Manitoba Finance charges a fee.

Penalty and interest

The FAQs refer to a regular 10 per cent late-filing penalty, and say assessments carry additional penalties that grow with the number of earlier assessments on the account. Outstanding debts also carry interest, compounded monthly, set each January 1 and July 1. The interest rates page shows 7.45 per cent for July 1 to December 31, 2026, down from 7.95 per cent in the second half of 2025. Check it again in January.

Notices of assessment, refunds and what you cannot claim

A Notice of Assessment is issued when a return has not been filed for a period. If you receive one, file the return as soon as possible, even if it is nil, and pay any balance. In TAXcess the status reads "Tax Assessed", and you select "View Return", then "Change". Processing takes one to two business days, after which the assessed amount is reversed and penalties are adjusted to the real figures.

For a refund of an RST credit, complete form R.T.6, Application for Refund, General Use, from the Manitoba tax forms page, or apply the credit to your next payment. The FAQs say refunds take about six to eight weeks, you must apply within two years of the date of the error, and a $25 administrative fee is deducted. The department mails a cheque.

One rule is worth underlining for anyone used to GST. Manitoba RST has no input tax credits. The FAQs say there is no deduction, credit or refund for RST paid on purchases for your business's own use, so equipment, supplies and taxable services carry a cost you cannot claim back.

The health and education levy, fuel, tobacco and IFTA

TAXcess handles several other returns, and the FAQs describe each one. We summarise the two most common.

HE levy monthly return. Under your Health and Education Levy account, select "File Now", enter gross payroll on line 2 (year-to-date payroll fills in), select "Next", review and submit.

HE levy annual report. Due March 31 for the previous calendar year. Only the primary account of an associated group may file it. Enter total remuneration on line 1, the exemption threshold on line 2 if remuneration is above it, and tax already paid on line 6. The report defaults to 4.3 per cent and recalculates as you enter associated companies. A refund request needs your T4 Summary. Tax found owing by the annual reconciliation counts as overdue if it was not paid by January 15, with a 10 per cent penalty and interest from the date it should have been remitted. So you can file the annual report on time and still see arrears.

Fuel tax returns can be imported from an Excel template or entered by hand, with a "No Activity" option for a nil return. Tobacco tax uses the T3 or T4 return with schedules, and IFTA filers report distance travelled and fuel purchased by jurisdiction.

Special situations: selling a business, liquor, First Nations and audits

• Selling a business. If you sold the assets and stopped operating, you must get a Bulk Sale Clearance Certificate by submitting the Bulk sale application form. There is no fee, and selling shares does not require one. A buyer pays RST only on the part of the price allocated to taxable tangible assets, using the Casual Purchaser's Return before the 20th of the month after the purchase. Vehicles are taxed through Manitoba Public Insurance at registration.
• Liquor and cannabis. A liquor licence means you must register for RST, and the $30,000 threshold does not apply. Medical cannabis and other taxable goods also require registration, though recreational cannabis is not subject to RST.
• First Nations exemption. It applies to First Nations individuals with a valid status card or Temporary Confirmation of Registration Document, certain bands and band-empowered entities, who take possession of goods or services on reserve land, including urban reserves. It does not extend to Métis, Inuit, non-status individuals or corporations. A vendor needs the card, and the receipt must carry the name, registration number and signature.
• Audits. The Taxation Division generally uses a six-year audit period, which can be shortened to four or two years where early findings show compliance. If you disagree with an assessment, the appeal must be in writing within 90 days, and an appeal does not change the payment due date. You can pay audit amounts through TAXcess.
• Records. Keep records for the current fiscal year plus six years, and general ledgers indefinitely, as Bulletin RST 016 requires. Electronic records are fine if they can be linked to source documents, and they must be available for audit in Manitoba.

The Primary Caregiver Tax Credit in TAXcess

Individuals meet TAXcess through this credit. According to the FAQs, first-time applicants use the "Apply for the First Time / Submit Renewal" link, and renewals follow the prompts. Requests usually take about ten business days, and the approval letter is e-mailed, though processing slows in tax season. A saved application is under "Find Saved Request", extra documents go through "Submit Supporting Documents", and the approval letter can be retrieved with "Verify Eligibility Details".

Care must be provided for longer than 90 days in a calendar year. Two caregivers can apply for the same recipient if their caring periods do not overlap, so the first caregiver must enter an end date. The recipient must live in an area under a Regional Health Authority, and care for someone living on a First Nations reserve does not qualify. We do not quote the credit amount here because we did not read it on an official page; the Manitoba government publishes it with the credit rules.

What changes for Manitoba vendors in 2026, 2027 and 2028?

Manitoba Finance's Budget 2026 tax bulletin, issued in March 2026, lists the changes announced in the March 24, 2026 budget address. Three touch vendors directly.

Date	Change	What it means for a vendor
July 1, 2026	The RST exemption on basic groceries expands to more food and drinks sold by grocery stores	Tills must stop charging RST on items such as ready-to-eat sandwiches, soups, rotisserie chickens, sushi and cold cut platters, chips and pretzels, salted nuts, carbonated drinks, single servings of sweetened baked goods and candy
July 1, 2026	Prenatal vitamins stop being subject to RST	Update the product list in your till
January 1, 2028	All businesses registered to collect RST must file, remit and pay electronically using TAXcess	Paper returns end for quarterly and annual filers, who until now were the only ones allowed to use them

The 2028 date matters most for small businesses. At present the vendors bulletin says monthly returns and payments must already go through TAXcess, while quarterly and annual filers may file on paper. A small shop that has filed one paper return a year will need a login, a working e-mail address and a habit of signing in. Our advice, not the government's: register for online access during a quiet month in 2027, not in December 2027.

The budget also tightens one rule: RST refunds on vehicle purchases and sales will be denied if a taxpayer falsified a bill of sale. The 7 per cent rate did not change and no new rate is announced for 2027. The two credits the budget raises for 2027 are income tax and school tax matters, covered in our guide to the Manitoba affordability credits for 2027.

A worked example: a Winnipeg gift shop

These figures are our illustration, not an official example. A gift shop sells $24,000 of taxable goods a month, steady through the year.

Step	Figure	How it works
RST collected at 7%	$1,680.00	Goes to Manitoba through the return
GST collected at 5%	$1,200.00	Goes to the CRA on a separate return
Average RST per month	$1,680.00	Between $500 and $4,999, so the shop files quarterly
RST due for a quarter	$5,040.00	Three months of $1,680.00

The January to March return is due by 4:30 p.m. on April 20, 2027. If the shop paid $100 of RST by mistake on stock it could have bought exempt for resale, it reports $4,940 on line 1 of a later return, within two years. In 2028 the same return and payment both go through TAXcess, so the owner needs an active login, a PAD source or a bank payee set up, and one person who knows the password.

Common mistakes, and how to avoid them

• Waiting for a reminder. You owe the return even if the e-mail never arrives.
• Skipping a nil return. Enter 0.00 and submit it.
• Paying at the bank and assuming that files the return. Bill payment is an account payment, and the return is separate.
• Using the account number to buy for resale. Only the 7-digit RST number does that.
• Mailing at the deadline. A postmark does not count, and 4:30 p.m. is the cut-off.
• Missing the $30,000 crossing. You have one month to register once sales pass it.
• Charging RST on newly exempt grocery items. Check your till against Bulletin 030 and the budget bulletin.
• Counting on input credits. Manitoba RST has none for your own purchases.
• Deleting a payment and forgetting the return. If you chose "PAD Payment" while filing, deleting the payment deletes the return too.

Have your RST number ready when you call, and quote your account number or BN when you e-mail. Inside the portal, the Messages tab lets you write to the department. The full TAXcess FAQs and tax forms are on the official sites. If you want to check a supplier, the portal offers a public RST and tobacco tax registry look-up. Our GST and PST calculator shows how both taxes add to a price, and the guide to GST, HST, PST and QST compares the provinces. The CRA's own example on charging and collecting the GST/HST uses a Winnipeg sale with 5% GST and 7% Manitoba PST.

What we could not confirm

We rechecked two figures on November 12, 2026: the January 1, 2028 electronic filing rule against Manitoba’s Budget 2026 tax bulletin, and the 7.45% interest rate against the Manitoba Finance interest rates page. We read the public front page of the portal and the official FAQs, but we did not sign in, so we have not described the screens behind the login beyond what the FAQs say. The credit amount of the Primary Caregiver Tax Credit and the penalty for returns after the regular 10 per cent are not stated in the documents we read. Anything that affects a decision should be confirmed with Manitoba Finance before you rely on this guide.

Frequently asked questions

What is TAXcess in Manitoba?

TAXcess is the online service of Manitoba Finance where businesses apply for tax accounts, file returns, pay and view their Manitoba tax accounts, and where individuals apply for the Primary Caregiver Tax Credit.

Is TAXcess the same as the CRA My Account?

No. TAXcess is run by Manitoba Finance for provincial taxes such as the 7% retail sales tax. The CRA runs its own portals for income tax, GST and payroll.

How do I register for TAXcess?

Sign up for a login with a user ID and password, sign in, choose Apply for New Tax Account(s) under Access Management and complete the application. Registration is free, and an approved application brings an e-mailed registration package.

How do I get online access to an account I already have?

Create a login, sign in and choose Add Access to Existing Tax Account(s). You will need your 15-digit account number and details from the most recently filed return, or 0 if none has been filed.

What if I forgot my TAXcess password or got locked out?

Click Forgot Password on the sign-in page, answer your security question and create a new password. A forgotten username is e-mailed to the address on the account.

Do I have to use TAXcess to file RST returns?

Monthly returns and payments must already go through TAXcess. From January 1, 2028, all businesses registered to collect RST must file, remit and pay electronically through it.

When are Manitoba RST returns due?

By 4:30 p.m. on the 20th day of the month after the reporting period, or the next working day if the 20th is a weekend or statutory holiday. Annual returns are due January 20.

Do I need to register if I sell less than $30,000 a year?

Not if your annual taxable sales are under $30,000 and you buy goods from sellers registered for Manitoba RST. Businesses that sell tobacco, liquor or taxable cannabis, or buy from suppliers that do not collect the tax, must register.

How do I pay my RST through TAXcess?

Set up a pre-authorized debit from a Canadian bank account. You can pay when you file, or choose Pay Later and schedule a payment up to 173 days ahead. You can also pay through your bank as Manitoba Retail Sales Tax.

What is the late-filing penalty for RST?

The TAXcess FAQs refer to a regular 10% late-filing penalty, plus interest on outstanding amounts, and say assessments carry extra penalties that rise with the number of earlier assessments.

What if I have no sales this month?

File anyway. Enter 0.00 in TAXcess. A missing return still counts as late.
