Updated Checked by the Tax-Services.ca editorial team How we check
Farm accounting in Canada starts with one choice: cash or accrual. The CRA lets most farmers pick either method for their farming income, but GST/HST reporting has to run on accrual. So if you choose cash for the income tax side, you’ll end up keeping two sets of numbers anyway.
Should a farm use the cash method or accrual?
Under the cash method you report income when the money arrives and deduct an expense when you pay it. Under accrual you report income when you earn it and deduct costs when you incur them, paid or not. Accrual also pulls inventory into the calculation: crops, feed, livestock, fertilizer and supplies on hand at year end.
Most farmers go with cash, and it’s easy to see why. You can sell a crop in January, bank the cheque, and the income lands in the new year. There’s no inventory count to build, and the tax follows the bank account.
Fine, but there’s a catch.
Nothing forces you to stay tidy. If you pay three years of input bills in one December, the year looks strange and your tax for that year shrinks. Next year it swings back.
| Question | Cash method | Accrual method |
|---|---|---|
| Income counted when | You receive it | You earn it |
| Expense deducted when | You pay it | You incur it |
| Inventory in the calculation | No | Yes, valued at year end |
| GST/HST reporting | Not allowed | Required |
| Switching in | Straightforward from accrual | From cash, you need CRA permission |
Can you switch methods later?
Going from accrual to cash is relatively easy. Going from cash to accrual is not: you need permission from your tax services office, and you have to ask in writing before your filing deadline and explain why. That’s a reason to think about the method before year one, not in year eight when the bank asks for accrual statements.
Inventory has its own choices once you use accrual. The CRA names three ways to value it: fair market value, the lower of cost and market, or for farmers a unit price base on form T2034. Pick one on purpose and write down why.
What does $50,000 of farm profit cost in tax?
Take a sole proprietor in Saskatchewan with $50,000 of net farm income. The self-employed tax calculator shows $6,451.01 of income tax and $5,533.50 of CPP, because you pay both halves. Together that’s $11,984.51, or 24.0% of the income, and $38,015.49 is left.
Two things that number leaves out. EI isn’t in the tool, and neither are business expenses or instalments. Net income in the box should already be after your farm costs. Since farm income can jump between years, the tax instalments calculator is worth a look once you’ve got a steady profit.
Which records does a farm keep?
The CRA form for the year is T2042, the statement of farming activities. You fill in a separate one for each farm business, and if you’re in AgriStability and AgriInvest you use the program form for your province instead. The guide behind it is chapter 2 of T4002.
Whatever the method, a few habits save you the most grief.
- Keep one bank account for the farm, so personal spending doesn’t leak into expenses.
- Write down the year-end count of grain, feed and livestock, even on cash, since lenders ask for it.
- File receipts by month and keep sales slips with the deposit they belong to.
- Track hired help apart from your own draws.
If you hire workers, the payroll remittance calculator shows what comes off each cheque and what you add on top. A seasonal hand on $1,500 every two weeks in Ontario means a remittance of $382.19 for that one pay period.
Where farm bookkeeping goes wrong
The big slip is mixing methods without a plan. You may use cash for farming income, but you have to use accrual for any other business activity and for GST/HST. Records for each method have to be kept apart.
Another is treating a cash year like a bank balance. A high balance in December isn’t profit, and a low one isn’t a loss. Look at what you sold and what you spent on inputs. The profit margin calculator turns those two totals into a margin you can compare year to year.
And don’t count on the calculators for the whole picture, because they know nothing about your capital cost allowance, your AgriStability claim, a spouse who works the farm with you, or the machinery loan you refinanced last spring.
Where the numbers come from
The method rules come from the CRA page on accounting methods for sole proprietors and partnerships, and the form details from the CRA T2042 pages. The example uses our 2026 calculator data for Canadian tax and CPP. We could not confirm farm-specific credits or deadlines for 2026, so check the CRA farmers and fishers pages for your year.
Frequently asked questions
Can a farmer use the cash method in Canada?
Yes. Farmers can choose cash or accrual for farming income. GST/HST reporting still has to use accrual.
Which form reports farm income?
The CRA form is T2042, Statement of Farming Activities, one per farm business. Farmers in AgriStability and AgriInvest use the program form for their province.
Can I move from cash to accrual?
You need permission from your tax services office and have to ask in writing before your filing deadline, with a reason.
How is inventory valued on accrual?
The CRA lists fair market value, the lower of cost and market, or a unit price base on form T2034 for farmers.
Does the self-employed calculator include EI?
No. It covers income tax and both halves of CPP, and leaves out EI, expenses and instalments.
