Trying to register for GST/HST, but don't know what documents you need? Here's your pre-registration checklist. 🗂️

The Problem: Most founders jump into CRA's Business Registration Online portal unprepared, only to abandon the process halfway through when prompted for information they don't have on hand. This creates delays, incomplete registrations, and missed input tax credit opportunities.

The Solution: Before opening the CRA portal, gather these five essentials:

  1. Your Business Number (BN): If you incorporated through Corporations Canada or provincially, you already have one. If not, you'll get it during registration.
  2. Legal and operating names: Your incorporated legal name plus any trade name (DBA) you use publicly.
  3. Business activity classification: Be specific. Most tech startups fall under "professional, scientific, and technical services." Vague classifications trigger CRA follow-up requests.
  4. Complete contact details: Business address, email, and banking information for future remittances.
  5. Filing frequency decision: Choose monthly, quarterly, or annual filing. Early-stage founders often select annual for simplicity, but quarterly filing helps manage refunds and track cash flow strategically.

Pro tip: If you use cloud accounting tools like QuickBooks or EIM's Cloud Accounting Solutions, pull these details directly from your system. It ensures consistency across your records, which the CRA expects.

The Outcome: With everything ready, registration takes 15-20 minutes, and you'll receive your GST/HST number immediately. No delays, no follow-up requests, and you can start claiming input tax credits right away.
