Real-time accounting means your books are updated as money moves, so you can see profit and tax owing today instead of after year end. For a Canadian owner, the biggest gain is the instalment date: knowing in September what you’ll owe, not finding out in April.
What does real-time accounting change for a small business?
It shortens the gap between an event and the record of it. A sale, a bill or a payroll run lands in the books the same day, so the profit figure you read on a Tuesday includes Monday’s invoices and Monday’s rent.
That matters for cash more than for tax. You can see whether Friday’s payroll is covered and whether the HST you’ve collected is still sitting in the bank. Both are money that isn’t yours to spend.
But “real-time” has a limit. The numbers are only as fresh as your last entry. An unposted invoice or an unmatched bank line makes the live view wrong, and a wrong number that looks current is worse than an old one.
How can live figures help you set tax money aside?
Take a sole proprietor with $80,000 of profit in Ontario. The self-employed tax calculator shows $13,233.57 of income tax and $8,892.90 of CPP, so $22,126.47, or 27.7% of income. If your live profit is tracking near that, set aside roughly a quarter of each deposit.
The calculator leaves out business expenses, GST/HST and EI, so the true share differs. Treat it as a starting guess and adjust as your profit figure firms up. If you’d rather keep it simple, move a fixed share of every deposit into a separate savings account the day it arrives, and true it up at each instalment date.
Instalments are next. The tax instalments calculator shows that an expected $9,000 of net tax owing means four payments of $2,250. It also shows a $3,000 threshold. Under it, instalments aren’t needed. For the 2025 year the CRA’s dates were March 15, June 15, September 15 and December 15, and we couldn’t find later dates yet.
What should you watch live?
| Figure | Why look at it often |
|---|---|
| Cash in the bank after tax set-asides | Shows what you can really spend |
| HST collected and paid | The return is due one month after the period for monthly and quarterly filers |
| Payroll to remit | Employer share is on top of wages |
| Year to date profit | Drives your income tax and CPP |
| Unmatched bank lines | Each one makes the live picture less reliable |
What about a company instead of a sole proprietorship?
A corporation has its own dates. The return is due six months after year end, and the balance is due two months after, or three for many small Canadian-controlled private corporations.
In the corporate tax calculator, $150,000 of active business income in Ontario comes to $17,544, or 11.7%. Ontario cut its small business rate on 1 July 2026, so the tool blends the rate for a calendar year. That blend is derived, not printed by the government, so a company with a different year end should expect a different result.
Where does live bookkeeping mislead people?
A big cash balance isn’t profit. It might be tax you’ve collected, a customer deposit or a loan.
Timing gets people too. A big bill that hasn’t been entered makes this month look great. And ignoring the instalment dates because the dashboard looks calm leads to interest charges.
We couldn’t confirm what any named software updates and how fast, so check how often your bank feed refreshes. Also ask whether the figures on screen include entries still waiting for review, since some views count them and some don’t.
One habit fixes most of this. Pick a day each week, post everything, then read the profit figure.
Where do the numbers come from?
Dates come from the CRA’s tax deadlines page, covering the 2025 tax year. Amounts come from our calculators, based on 2026 federal and Ontario rates. This site isn’t linked to the CRA.
Frequently asked questions
What is real-time accounting?
It's bookkeeping where entries are posted as transactions happen, so profit and cash are visible now instead of at year end.
Does real-time accounting cut my tax bill?
No. It shows what you owe sooner, which helps you set money aside and time instalments.
When do I need to pay tax instalments?
The CRA's dates for the 2025 year were March 15, June 15, September 15 and December 15. Our instalments calculator uses a $3,000 threshold of net tax owing.
How current are real-time numbers?
As current as your last entry and your bank feed. Unposted bills and unmatched lines make them wrong.
How much should I set aside for tax?
For $80,000 of Ontario profit, our calculator shows about 27.7% for income tax and CPP before expenses. Your real share will differ.
