AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A small Canadian corporation files its first T2 within six months of its first tax year-end and pays any balance within two months (three for a CCPC claiming the small business deduction, if conditions are met). The return includes the GIFI financial statement schedules and Schedule 50 for shareholders, plus T1135, T106 or T1134 if their triggers apply. Naira sales are reported in Canadian dollars, since the naira cannot be a functional currency.
Deadlines for the first return
The government's 2026 deadline page (modified 16 October 2026) sets the core dates for corporations:
| Item | Due |
|---|---|
| T2 return | within six months of the tax year-end |
| Balance of tax owing | two months after year-end; three months for a CCPC claiming the small business deduction, if the conditions on the CRA's balance-due page are met |
| Instalments | monthly or quarterly once required |
| T4 slips if you paid salary | last day of February |
The filing deadline and the payment deadline are different. A company with a 31 December year-end files by 30 June but, if it owes tax, typically pays by 28 or 29 February or 31 March. Interest runs on late payments even if the return is on time.
What the return is made of
The CRA's T2 guide (28 May 2026) lists the schedules most small companies meet:
- GIFI Schedule 100 (balance sheet) and Schedule 125 (income statement), completed from your financial statements;
- Schedule 141, questions about who prepared the statements and what the notes contain;
- Schedule 50, if you are a private corporation and any shareholder holds 10% or more; list up to the top 10 shareholders; and
- the schedules for the small business deduction and provincial tax, which your software builds from your figures.
Foreign forms that may apply
| Form | Trigger in the T2 guide | Typical case |
|---|---|---|
| T1135 | specified foreign property costing over $100,000 (simplified method under $250,000) | a Nigerian bank account held by the Canadian company |
| T106 | reportable transactions with non-residents over $1,000,000, plus other conditions; due within six months | large service fees to a related Nigerian company |
| T1134 | a non-resident foreign affiliate; due within 10 months | a Nigerian subsidiary |
Selling to unrelated Nigerian customers does not by itself trigger any of these. Holding the sales proceeds in a Nigerian account can, once the cost of foreign property passes $100,000. See T1135 for Nigerian bank accounts.
Recording naira sales
The company reports in Canadian dollars. The CRA's functional currency election is open only for the British pound, euro, Australian dollar, US dollar and Japanese yen, so a company earning in naira cannot elect to report in naira. On rates, the CRA's functional currency page points to the Bank of Canada daily rate for the day, to four decimal places, and the closest preceding day if no rate was quoted. If you cannot find a naira rate from that source for a date, document the source you used and apply it consistently, and ask your accountant how it fits the CRA's rules; our guide on the exchange rate for naira income covers the options.
Worked example
Example: on 14 May the company invoices a Lagos client ₦3,000,000. Using an assumed rate of ₦1,000 = C$1 for this example only, the sale is booked at C$3,000. The client pays on 20 June when (again as an example) the rate is ₦1,100 = C$1, so ₦3,000,000 arrives as C$2,727.27. The C$272.73 shortfall is a foreign exchange loss, recorded separately from the sale. Use the actual rates for each date in your books. See FX gains and losses on naira payments.
Nigerian withholding tax on your sales
Nigerian clients may deduct withholding tax from service fees. Book the full invoice as revenue and the deduction as tax paid, and keep the credit note; you may be able to claim a foreign tax credit. See Nigerian WHT on consultant fees.
Choosing a year-end and keeping clean books
Your first tax year starts on the date of incorporation. Many small companies choose a year-end that falls outside their busiest season so that the accountant has time; a company selling into Nigeria around Christmas and Easter might avoid a December year-end. Whatever you choose, run the company's money through its own accounts only. Mixing personal transfers to family in Nigeria with company receipts is the most common reason a first T2 takes months to finish. Keep each naira invoice, the payment record, any withholding tax credit note, and a note of the exchange rate source for that date. Good records also make it easier to answer CRA questions later about foreign income.
Steps before filing
- Close the books at year-end: reconcile every bank account, including any naira account, to statements.
- Prepare financial statements and map them to GIFI codes.
- List shareholders for Schedule 50.
- Check the cost of foreign property, related-party transactions and any subsidiaries against the T1135, T106 and T1134 triggers.
- File the T2 within six months, and pay any balance by the earlier balance-due date.
Where Pryme fits
A Pryme Business Account can hold the naira and dollars your Nigerian clients pay, and verifiable statements from VerifyDoc.ai give your accountant records that can be checked as genuine and unaltered. The Finance agent prepares reconciliations; a person approves.
Questions people ask
When is my first T2 due?
Within six months of the end of the company's first tax year. Any balance owing is due two months after year-end, or three for a qualifying CCPC.
Can my Canadian company report in naira?
No. The functional currency election covers only the pound, euro, Australian dollar, US dollar and yen.
Do Nigerian sales mean I must file T1135?
Not by themselves. T1135 applies if the company holds specified foreign property, such as a Nigerian bank account, costing over $100,000.
Where do I put Nigerian withholding tax on my T2?
Record the full sale as revenue and the withheld amount as tax paid; ask your accountant about a foreign tax credit.
