GST Registration: What Every BC Tradesperson Needs to Know Before They Hit $30,000

GST registration every BC tradesperson needs to know. Here's a situation that plays out more than it should: a tradesperson goes independent, builds momentum, has a good first few months and then gets a letter from CRA because they crossed the GST registration threshold without knowing it or knowing what to do about it. It's not because they were doing anything wrong. It's because nobody explained the rules clearly before they started.

The Basics

In Canada, you're required to register for GST/HST once your business revenues exceed $30,000 in a single calendar quarter, or in four consecutive quarters. That threshold is lower than most new operators expect especially in the trades, where individual jobs can be several thousand dollars. Once you cross it, you're required to collect 5% GST on your invoices and remit it to CRA on a regular schedule. You also get to claim input tax credits meaning you recover the GST you pay on business purchases.

Why You Should Register Early

Most tradespeople starting out think: I'm not required yet, so I'll wait. There's actually a strong argument for registering from day one. If you're billing commercial clients or other businesses, they're going to expect a GST number on your invoice. Not having one can signal that you're very new or very small neither of which helps you position yourself professionally. Registering early also means you start recovering GST on your tool purchases, materials, vehicle costs, and other business expenses immediately. That's real money back in your pocket from the first invoice.

The Filing Mistake That Costs Operators

GST collected is not your money. It's tax you're holding on behalf of CRA until you remit it. The mistake that gets operators into trouble is treating that money as available revenue, spending it on operations or drawings and then having nothing to remit when the filing deadline arrives. The fix is simple: every time you invoice GST, transfer that 5% into a separate account. Call it your tax account. Don't touch it. When the filing comes due, the money is there.

One More Thing

GST registration is separate from your income tax obligations. GST is collected on your billings. Income tax is calculated on your net profit. Both have different filing schedules and different rules. Confusing the two is one of the most common errors new operators make.

Get the structure right before you start billing. It's a lot easier to set up correctly from the beginning than to untangle it after the fact.
