GST/HST registration, filing and peace of mind
We register you, file your returns on time, and reconcile your input tax credits, so you claim what you’re owed and never get a surprise letter from the CRA.
What GST/HST filing includes
Sales tax trips up more owners than any other filing. We keep your GST/HST accurate and on schedule, reconcile it against your books, and make sure every eligible input tax credit is captured, nothing left on the table, nothing that invites a review.
GST/HST filing support also includes checking whether registration was required at the right time, whether the filing frequency still fits your sales volume, and whether the bookkeeping actually supports the return. If the account is behind, we rebuild the periods, separate taxable and exempt sales, review input tax credits and prepare the explanation you may need if CRA asks for backup.
We also keep the GST/HST account connected to monthly bookkeeping, so balances, payments and credits can be checked before a filing is submitted.
The result is a GST/HST filing record that is easier to trace, explain and repeat each period.
GST/HST support also looks at timing. Registration, filing frequency, payment deadlines and input tax credit claims can all change depending on revenue, industry and how quickly the business is growing. We check whether you should register now, whether voluntary registration makes sense, and whether old periods need to be corrected before a new filing rhythm begins.
Sales tax also needs clean source records. We check whether revenue was taxable, zero-rated or exempt, whether expenses include recoverable tax, whether payments posted to the right period and whether prior filings need adjustment. That practical review is what keeps the return defensible.
We keep the filing note short and useful, with the period, balance, payment status and any records to keep handy.

GST/HST questions we hear a lot
Do I need to register for GST/HST?
Generally once your taxable revenue passes $30,000 over four consecutive quarters, but voluntary early registration can help you claim ITCs. We’ll advise on timing.
The GST/HST small supplier threshold is only the starting point. We also look at when taxable supplies were made, whether related businesses affect the calculation, whether customers expect tax on invoices, and whether early registration would let you recover input tax credits. Timing the registration properly can prevent awkward corrections later.
What’s the quick method, should I use it?
The quick method simplifies filing and can save money for some service businesses. We compare it against the regular method for your numbers.
Choosing a GST/HST method should be deliberate. The regular method, quick method and annual or quarterly filing options can affect cash flow and bookkeeping habits. We compare the numbers, explain the recordkeeping required and help you choose the setup that fits your business instead of copying what another owner uses.
We explain the choice in dollars and workflow. Some owners save time with a simplified method, while others need the regular method because their input tax credits are material. The right answer depends on your receipts, customers and bookkeeping habits.
I missed a few filing periods. What now?
We file the outstanding periods, reconcile the credits, and help minimise penalties and interest with the CRA.
Behind GST/HST filings can usually be cleaned up with the right order of work. We reconcile sales, expenses, credits and payments first, then prepare the missing returns and explain any balance owing. If penalties or interest are involved, we help you understand what can be reduced and what simply has to be paid.
If there are several missing periods, we usually rebuild them oldest to newest so payments, credits and carry-forwards line up. That reduces the chance of filing one return correctly and creating a mismatch in the next one.
Can you file GST/HST as part of my bookkeeping?
Yes, that’s the ideal setup. Reconciled books make for accurate, defensible GST/HST returns.
GST/HST is easier when bookkeeping stays current. Monthly reconciliations make it clear which invoices were collected, which expenses include tax, which purchases need receipts and which balances have already been paid. That means each filing period starts with facts, not a last-minute search through email.
