Q2 Financial Check-In: 6 Things Every Ontario Business Owner Should Review Right Now

Most Ontario small business owners do a serious review of their finances exactly once a year: in the weeks leading up to tax filing. Everything is pulled together, documents are gathered, the accountant is called, and then — with relief — it's over for another year.

But there's a much smarter approach, and it starts right now, at the midpoint between January's year-start and December's year-end.

Q2 — April through June — is the ideal moment for a financial mid-year check-in. Deadlines have just passed (or are passing). The year is young enough that you still have time to adjust. And the decisions you make now will determine whether December feels manageable or overwhelming.

Here are six things every Ontario business owner should be reviewing right now — with the specific CRA rules and numbers that make each one matter.

1. HST Instalments: Are You Paying the Right Amount?

Many Ontario business owners don't think about HST between filing periods — but if you're an annual HST filer who owed more than $3,000 in HST last year, CRA requires quarterly instalment payments throughout the current year.

📋 For annual HST filers with net tax owing of more than $3,000 in the previous year, quarterly instalments are due: March 31, June 15, September 30, and December 31. | Source: canada.ca — GST/HST instalments (CRA)

The Q2 instalment is due June 15. If your business revenue has changed significantly since last year — either grown or declined — your instalment amount may need to be recalibrated. Overpaying ties up cash flow unnecessarily. Underpaying triggers interest charges.

The three methods CRA allows for calculating instalments are: (1) equal payments based on prior year net tax, (2) equal payments based on an estimate of current year net tax, or (3) a specific calculation method. Each has different risk profiles depending on your revenue trajectory.

What to do right now:

Compare your Q1 actual HST collected and paid against the same period last year. If your revenues differ significantly, recalculate your instalments and adjust accordingly. Your bookkeeper should be providing you with this data as part of regular monthly reporting.

2. Passive Income Tracking for Incorporated Businesses

If your business is a Canadian-controlled private corporation (CCPC) and it earns investment income — interest, dividends, or rental income — you need to track it carefully throughout the year.

Here's why: the federal small business deduction (which reduces your corporate tax rate to 9% on active business income) starts to phase out when your corporation's passive income exceeds $50,000 in the prior year. At $150,000 or more in passive income, the small business deduction is eliminated entirely, and your full $500,000 of active income is taxed at the general corporate rate instead.

📋 For every $1 of passive income above $50,000, the business limit eligible for the small business deduction is reduced by $5. At $150,000 in passive income, the deduction is fully eliminated. | Source: canada.ca — What's new for small businesses (CRA)

In dollar terms, the difference between the small business rate (a combined federal and Ontario rate of approximately 12.2%) and the general corporate rate (a combined rate of approximately 26.5%) on $500,000 of income is roughly $71,500 per year. This is not a minor planning consideration.

What to do right now:

Ask your bookkeeper for a year-to-date report on your corporation's investment income. If you're approaching $50,000, this is an urgent conversation to have with your accountant — and there are legitimate strategies available that may help, but they require time to implement.

3. Shareholder Loan Review

If you're an incorporated business owner, it's very likely that you've transferred money between your personal account and your corporation at various points this year. Maybe you borrowed from the corporation to cover a personal expense. Maybe you lent the corporation money to bridge a cash flow gap. These transfers need to be properly documented and tracked — and CRA has strict rules about how long they can remain outstanding.

📋 A loan from a corporation to a shareholder must be repaid within one year following the end of the corporation's fiscal year in which the loan was made. If it's not repaid, the full outstanding balance is added to the shareholder's personal income — regardless of repayment status. | Source: canada.ca — Shareholder benefits and loans (CRA)

The Q2 review is the right time to look at your shareholder loan balance and calculate the repayment deadline. If the deadline is approaching, you need to know now — not in November.

What to do right now:

Pull your shareholder loan account from your bookkeeping records. Confirm the balance as of today and the date each advance was made. Calculate the repayment deadline based on your corporation's fiscal year-end. If repayment isn't feasible, discuss alternatives (such as documenting the transfer as salary or dividends) with your accountant before the deadline.

4. Vehicle Expense Documentation: Is Your Mileage Log Current?

Vehicle expenses are one of the most commonly audited deduction categories for Ontario small businesses. CRA's position is straightforward: if you want to deduct vehicle expenses, you need contemporaneous records — not reconstructed year-end estimates.

A compliant mileage log records, for every business trip: the date, the starting and ending location, the business purpose, and the number of kilometres driven. CRA does not accept annual estimates or percentage-based claims without supporting trip-by-trip documentation.

By Q2, if you've been using your vehicle for business since January, you already have four months of trips that need to be in your log. If you've been keeping up with it, great. If you haven't, now is a much better time to reconstruct and catch up than December.

What to do right now:

Review your mileage log — or start one. Apps like MileIQ or DriverNote can automate most of the process by using your phone's GPS to track trips. Export a report at the end of each month and file it with your business records.

5. Q1 Payroll Reconciliation

If you have employees, your Q1 payroll records should be fully reconciled before you move any deeper into Q2. This means confirming that your payroll remittances to CRA match your payroll records, that your employee T4 data is being tracked accurately for year-end, and that your CPP and EI rates are correct.

📋 For 2026, the CPP employee and employer contribution rate remains at 5.95% on maximum pensionable earnings of $72,500. The EI premium rate for employees is $1.66 per $100 of insurable earnings, on earnings up to $65,700. | Source: canada.ca — Payroll deductions and contributions (CRA)

Payroll rate errors that aren't caught until year-end often result in either over-remittance (money you could have used in your business sits with CRA) or under-remittance (which triggers penalties and interest). A Q2 reconciliation catches these errors while they're still manageable.

What to do right now:

Pull your payroll register for January through March. Confirm that CPP and EI deductions were calculated correctly against the 2026 rates. Reconcile your remittance records against your CRA payroll account through My Business Account. If there are discrepancies, address them immediately — the longer they go uncorrected, the more expensive they become.

6. Ontario Tax Credits You May Be Missing

Ontario has several business tax credits that are underutilized by small business owners — often because the bookkeeping required to support the claim isn't being done throughout the year.

Ontario Made Manufacturing Investment Tax Credit

Ontario's May 2025 budget enhanced this credit to 15% (from the original 10%) for eligible Canadian-controlled private corporations investing in manufacturing or processing equipment and clean technology. The credit is refundable, meaning you receive it even if you owe no tax.

To claim it, you need purchase documentation for qualifying equipment, records showing the equipment's use in eligible manufacturing activities, and proper capital cost allowance (CCA) tracking in your bookkeeping records.

Ontario Innovation Tax Credit (OITC)

Ontario small businesses conducting eligible scientific research and experimental development (SR&ED) can claim the OITC at a rate of 8% on qualifying expenditures. This stacks on top of the federal SR&ED Investment Tax Credit.

The key here is contemporaneous documentation — project descriptions, time tracking, materials used, and contractor records need to be maintained as the R&D activity happens, not reconstructed at year-end.

What to do right now:

Review your Q1 capital expenditures and any qualifying research activities. Flag anything that may be eligible for provincial tax credits, and ensure supporting documentation is in place. Your bookkeeper should flag these categories as expenses are recorded, not leave them for your accountant to discover in February.

The Value of a Q2 Check-In vs. a Year-End Scramble

Every item on this list is something that can be addressed either now, in Q2, when there's still time to adjust, or in December, when the year is over, and your options are limited.

The business owners who feel most in control of their finances aren't the ones with the most sophisticated accounting software. They're the ones who review their numbers regularly, ask the right questions, and make adjustments while there's still room to move.

A Q2 check-in with your bookkeeper should take no more than an hour. The information it produces is worth significantly more than that.
