#### Registration & nexus threshold

Alberta has no provincial sales tax to register for. You only register for the federal GST, which is required once your taxable revenue exceeds CAD $30,000 over four consecutive calendar quarters. Non-resident digital businesses register under the simplified GST/HST regime at the same threshold.

How to register for GST in Alberta:

- Confirm you've crossed CAD $30,000 in taxable sales over four consecutive quarters.

- Gather your details — business name, Business Number, and activity.

- Register with the CRA for a GST/HST account.

- Receive your account and assigned filing frequency.

- Begin charging 5% GST and file with the CRA.

#### Filing frequency & deadlines

The CRA assigns monthly, quarterly, or annual GST filing based on revenue. Monthly and quarterly returns are due one month after the reporting period; annual filers generally have three months.

#### Exemptions

Basic groceries, prescription drugs, and many medical devices are zero-rated. With no provincial sales tax, only the 5% GST applies to taxable goods and services. SaaS and digital products are subject to GST.

## Resale & Exemption Certificates

Alberta has no provincial sales tax, so there are no provincial resale or exemption certificates. A GST/HST registrant recovers the tax paid on goods bought for resale and other business inputs by claiming input tax credits on its return [5].

#### Penalties

Filing GST late carries the CRA penalty of 1% of the amount owing plus 25% of that 1% for each full month the return is late, up to 12 months, plus interest.

## Audits & Appeals

The CRA audits GST in Alberta. To dispute an assessment, file a Notice of Objection (Form GST159) within 90 days of the assessment date; if still unsatisfied, appeal to the Tax Court of Canada [6].
