Alberta Business and Tax Compliance: Registry, AT1, No PST and WCB

Alberta business and tax compliance has one feature that surprises owners moving from other provinces: Alberta runs its own corporate income tax. Alberta corporations file a separate Alberta Corporate Income Tax Return (AT1) with Tax and Revenue Administration (TRA) in addition to the federal T2 filed with the Canada Revenue Agency (CRA). Alberta also has no provincial sales tax, which keeps retail and service pricing simple. This page covers incorporation, annual returns, tax rates, payments and workers' compensation for owners in Calgary, Edmonton, Red Deer and Lethbridge, including U.S. and India-linked owners.

Alberta business and tax compliance: how do you incorporate?

Alberta incorporates through its Corporate Registry, using registry agents rather than a single national website.

1. Choose a name with a distinctive element, a descriptive element and a legal element such as Ltd. or Inc.
2. Order a NUANS report from a provider. It must be less than 91 days old when you submit.
3. Collect the forms: Articles of Incorporation and, optionally, a Notice of English/French Name Equivalency.
4. Record the address: a physical registered office in Alberta and a Notice of Address.
5. Elect at least one director and file a Notice of Directors. Directors must be adults.
6. Appoint an agent for service, an Alberta resident who accepts legal documents for the corporation.
7. Submit the package to a registry agent with the forms, NUANS report, valid ID and payment.

An email address is required when you incorporate and when you file annual returns. Reminders go by email about two weeks before a return is due, and directors receive copies of missed-return notices by mail. A corporation formed in another province or country must register in Alberta before carrying on business there if, for example, it solicits business in the province, has an office or resident agent there, or owns Alberta land. If its home jurisdiction is British Columbia, Manitoba or Saskatchewan, Alberta offers free online extra-provincial registration. The federal alternative is explained in our incorporation guide.

What are Alberta's corporate tax rates?

CCPCs in an associated group share the business limit. The small business rate applies only to a CCPC; a corporation controlled by non-residents pays the general rate. See the small business deduction guide.

How does the AT1 work, and how is Alberta tax paid?

A corporation with a permanent establishment in Alberta at any time in the year generally files the AT1 unless it is exempt. The return is due six months after the end of the tax year and counts as filed when TRA receives it. Most corporations with tax years starting after December 31, 2024 must file through Net File with TRA-certified software; insurance corporations, non-resident corporations, corporations reporting in functional currency and some exempt corporations are excluded.

A corporation needs a Corporate Account Number (CAN) to net file. It matches the Corporate Access Number on the Alberta certificate of incorporation, and an out-of-province corporation must be registered in Alberta to get one. TRACS, TRA Client Self-Service, lets you confirm filings, view balances, set up direct deposit and request penalty or interest relief; from April 1, 2026 it is also the default way TRA sends most correspondence.

Tax is generally paid in monthly instalments due the last day of each month of the tax year, with any balance due by the end of the second month after year-end. A CCPC meeting TRA's criteria can defer the balance to the end of the third month. A weekend or holiday moves the date to the next business day, and late payments accrue daily compound interest. The federal T2 and the AT1 are independent filings, so keep both on the CRA deadline calendar.

Which other taxes and programs apply?

• Sales tax: the CRA table lists Alberta provincial sales tax at 0%, so the 5% GST is the only retail tax. See the GST/HST guide.
• Payroll: CPP, EI and income tax follow the federal rules; see the payroll guide.
• Workers' compensation: WCB Alberta administers workers' compensation, and employers use its myWCB portal. Check early whether your business must register.
• Registry maintenance: file annual returns and keep the registered office and agent for service current.

Worked example: an Edmonton fabrication company

Prairie Steel Works Ltd. is an Edmonton CCPC with $350,000 of active business income in 2026 and no associated corporations. Federal tax at 9% is $31,500 and Alberta tax at 2% is $7,000, so the total is $38,500, or 11%. If a U.S. parent owned a majority of its shares and made it a non-CCPC, the same income would face 15% federal plus 8% Alberta, or 23%, which is $80,500. The company files its T2 with the CRA and its AT1 with TRA, both due six months after its year-end, and pays Alberta instalments monthly through the year.

Documents to have ready

• NUANS report or numbered-name decision and the proposed articles.
• Director names, addresses and ID; the agent for service's details.
• Registered office address in Alberta and an email address for the registry.
• CRA business number and program accounts; Corporate Account Number once issued.
• Financial statements and tax working papers for the AT1.

Mistakes to avoid

• Filing the T2 and assuming the AT1 is covered; they go to different agencies.
• Missing the Net File requirement and paying the $1,000 penalty.
• Letting a NUANS report lapse beyond 91 days.
• Forgetting that an out-of-province corporation must register in Alberta before it carries on business.
• Assuming "no PST" means no sales tax; the 5% GST still applies.

A note for U.S.- and India-linked owners

A U.S. or Indian parent that operates in Alberta through a corporation is usually a non-CCPC and pays the 23% combined rate, and it must register extra-provincially if it is not itself an Alberta corporation. Alberta energy and technology groups often use Alberta subsidiaries; see our U.S. company entering Canada and Indian company entering Canada pages, the U.S.-Canada tax treaty guide and India-Canada business structures. For the U.S. reporting that follows an Alberta subsidiary, see our foreign business reporting guide; for the Indian side of an overseas investment, see India FDI and FEMA reporting.
