When to hire an accountant for your small business
Six concrete triggers that tell you it's time to hire an accountant for your small business — incorporation, bank requests, GST/QST, payroll and more.
There is a difference between asking whether your corporation is required to have an accountant — it isn't, and we cover that honestly in Do I need an accountant for my corporation? — and asking when hiring one becomes the smart move. The second question has the more useful answer, because the right moment is rarely a date on the calendar. It's an event. Here are the six triggers we see most often, what changes at each one, and what an accountant actually does about it.
You incorporated
Incorporation is where do-it-yourself tax quietly stops scaling. Your business becomes a separate taxpayer with its own fiscal year-end, and it must file a T2 corporate return every year — plus a CO-17 if it has an establishment in Québec — even in a year with no revenue. The first return sets patterns you will live with: your year-end date, your GIFI account mapping, how money moving between you and the corporation gets recorded. And the payment deadline for corporate tax arrives months before the filing deadline, which surprises almost every new owner-manager.
What an accountant does: choose a year-end that fits your cash cycle, set up the books so the first T2 is clean rather than a reconstruction, and file both returns on the schedules that actually apply to your corporation.
A bank asked for financial statements
The exports from your accounting software will not do. Lenders generally want financial statements prepared by an independent CPA under Canadian standards — a compilation engagement at minimum, sometimes a review depending on the loan. You cannot issue those yourself, and producing them in the middle of an application adds weeks to financing you needed yesterday.
What an accountant does: prepare compilation or review engagement statements the bank will accept, and tell you which level you need before the banker does. If you are not sure, our assurance level calculator gives you a first answer in two minutes.
Your revenue crossed the GST/QST threshold
Once your worldwide taxable sales exceed $30,000 over four consecutive calendar quarters — or in a single quarter — you stop being a small supplier. You must register, start charging tax, and you generally have 29 days to do it. This trigger sneaks up on owners because it is measured on a rolling basis, not by fiscal year.
What an accountant does: register you on time (or fix a late registration), pick a filing frequency that suits your cash flow, and make sure you claim the input tax credits you are entitled to — the money most self-registrants leave behind.
You hired your first employee
From the first pay run, you are withholding the government's money. You need a payroll account, you must deduct income tax, CPP or QPP contributions and EI premiums from each pay, and remit them — for most new employers, by the 15th of the month after you deducted them. In Québec, a parallel set of source deductions (the DAS) goes to Revenu Québec, along with employer contributions such as the health services fund. Late or short remittances draw penalties quickly, precisely because it is someone else's tax money.
What an accountant does: open the accounts, set up the pay calculation and the remittance calendar before the first pay date, then handle the T4s and Relevés 1 at year-end.
A letter from the CRA or Revenu Québec arrived
Most letters are routine — a processing review, a request for documents, an instalment reminder. But routine letters carry firm deadlines, and a slow or defensive answer is how routine turns into a full review. If you have read a letter twice and still are not sure what it is asking, that is the trigger.
What an accountant does: respond in the agency's language, supply exactly what was requested — no more — and represent you so the follow-up calls stop landing on your desk.
You're planning a big move
Buying a building, selling the business, bringing in a partner, setting up a holding company: these decisions carry the largest tax consequences of your business life, and almost all of the planning value exists before the transaction. Selling shares that qualify for the lifetime capital gains exemption can shelter over $1.25 million per shareholder — but the shares must meet the tests, in part for the 24 months beforehand. That is not something you fix at signing.
What an accountant does: structure the deal early — timing, holding company, purification, valuation support — so the tax result is designed rather than discovered.
The pattern across all six: the right moment to hire an accountant is when the trigger appears, not when the deadline does. If one of these has already happened in your business, see our transparent pricing — corporate returns from $1,475, compiled financial statements from $2,900 — or talk to us.

Frequently asked questions
When is the right time to hire an accountant for a small business?
When a structural trigger hits: you incorporate, a lender asks for financial statements, your sales cross the $30,000 GST/QST threshold, you run your first payroll, a CRA or Revenu Québec letter arrives, or you are planning a major transaction. Any one of these is reason enough on its own.
Should I hire an accountant as soon as I incorporate?
Before your first corporate year-end is the ideal window. The first T2 sets your year-end date, your account structure and how shareholder transactions are recorded — getting those right the first time costs far less than rebuilding them later.
Do I need an accountant to register for GST/QST?
No — you can register yourself. Registration is the easy part; the judgment calls are the filing frequency, the input tax credits and whether voluntary registration before the $30,000 threshold makes sense for your expenses. That is where an accountant earns the fee.
How much does an accountant cost for a small incorporated business?
At Stamped, corporate tax returns (T2 and CO-17) start at $1,475 and compiled financial statements start at $2,900, with prices published before work begins.
Can I wait until tax season to hire an accountant?
You can, but most triggers do not wait for tax season: payroll remittances are monthly, the GST/QST threshold is measured over calendar quarters, and government letters carry their own deadlines. Hiring at the trigger costs the same and prevents the cleanup.
