Accrual versus cash accounting sounds like a debate only accountants could love, but it decides something every business owner cares about: when your income and expenses count. Get the concept once and a whole category of confusing bookkeeping moments — and one common CRA misunderstanding — clears up for good.
You finish a project and invoice a client in December. They pay you in January.
Cash accounting says the income happened in January, when the money arrived. Accrual accounting says the income happened in December, when you earned it — the January payment just settles a debt the client already owed you.
Same dollars, different year. And the same logic runs on the expense side: the contractor who bills you in December for work done in December is a December expense under accrual, even if you pay the bill in January. Cash accounting tracks the movement of money; accrual accounting tracks the economic events the money is settling.
Here's the part that catches people: for most businesses, the CRA generally expects income to be reported on an accrual basis. That December invoice usually belongs in December's tax year whether or not it's been paid. There are exceptions for certain taxpayers and types of income — farmers and fishers have their own rules, and some professional and employment income works differently — but "I'll report it when they pay me" is not the default for business income, even though it feels like it should be.
This is one of the more common surprises in DIY books we take over: revenue recorded off bank deposits, invoices ignored, and a year-end that quietly shifted income into the wrong tax year. If that describes your books, the fix is a conversation, not a crisis — but it's a conversation to have before filing, not after.
Tax rules aside, accrual is simply the more honest way to look at your own business.
Imagine a strong November: three big projects delivered, all invoiced, none yet paid. Cash-basis books show November as a terrible month — no deposits — and January as a windfall. Accrual books show what actually happened: November earned the money, January merely collected it. If you're judging whether the business is growing, which picture do you want to steer by?
The same distortion works in reverse on expenses. Pay a full year of insurance in one month and cash-basis books show a spending spike that makes that month look worse than it was. Accrual spreads the cost across the months the insurance actually covers, so each month carries its real burden.
Owners who run on cash-basis instinct tend to feel rich right before tax time and poor right after invoicing — the numbers whipsaw with payment timing instead of performance.
The machinery that makes accrual work is two running lists. Accounts receivable (AR) is everything you've earned but not yet collected — your invoices out. Accounts payable (AP) is everything you owe but haven't yet paid — the bills in. Together they bridge the gap between economic events and cash movements, and they answer two questions cash-basis books can't: who owes me money, and what's about to leave my account?
Reviewing AR and AP monthly is also your early-warning system for collections — the invoice drifting past sixty days shows up on a list instead of in your overdraft. It's a standard part of every monthly close our bookkeeping team runs, and one of the checkpoints in a good mid-year review.
Cash accounting tracks money moving; accrual tracks value earned and owed — and for most Canadian businesses, accrual is both what the CRA generally expects and the version of your numbers worth steering by.
