For contractors

Books and GST/HST for Canadian contractors

Renovation and construction work is rarely one invoice. Deposits, progress payments and a pile of supplier receipts all have to line up at tax time. Keep them in one place as you go.

No credit card needed.

  • Deposits on quotes that come off the final invoice
  • GST/HST worked out for the province where the job is
  • Snap supplier receipts on site, sorted by T2125 line
  • Receipt check for the supplier GST/HST number on purchases of $100 or more
  • A running set-aside number for sales tax, income tax and CPP
  • Reminders 14 days and 3 days before each CRA date

What usually goes wrong

  • Deposits taken by text message

    Money taken without an invoice is hard to match up later. Put the deposit on the quote, invoice it, and it comes off the final bill automatically.

  • A truck full of faded receipts

    Materials receipts are where your input tax credits live. Snap each one when you buy, and the receipt check tells you if the supplier's GST/HST number is missing.

  • No idea what you owe until April

    Home keeps a running total of the sales tax you collected less the tax you paid on materials, plus a rule-of-thumb amount for income tax and CPP.

The tax reality for contractors

Construction and renovation work is generally a taxable supply, so GST/HST applies at the rate for the place of supply. In Ontario that is 13% HST.

GST/HST you pay on materials and tools can come back to you as input tax credits once you are registered. That is why many contractors register before the $30,000 limit forces them to, and why every supplier receipt matters.

British Columbia and Saskatchewan have their own PST rules for real property contracts. In general, contractors there pay PST on materials rather than charging it to the customer. Confirm your situation with your accountant.

Common questions

Can I invoice a deposit before starting the job?
Yes. Add a deposit to the quote. When the customer accepts, you invoice the deposit, and it is taken off the final invoice.
What if the job is in a different province?
Tax follows the place of supply, which for most jobs is where the work is done. CollabNorth warns you when the customer's province differs from yours, and you can change the place of supply on the invoice.
Can I track my truck and tools?
Expenses are sorted by T2125 line, including motor vehicle expenses. Capital cost allowance on equipment isn't worked out in the app yet, so add it yourself or with your accountant.
