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
Both the Ontario Trillium Benefit and the federal credit formerly called the GST/HST credit, renamed the Canada Groceries and Essentials Benefit from July 2026, are based on your adjusted family net income from your tax return. As a Canadian resident, that net income includes world income, so Nigerian rent, interest or wages count in full even if Nigeria taxed them; the Nigerian tax reduces your tax through a credit but does not reduce net income.
Why benefits look at world income
Income-tested benefits in Canada are calculated from the net income on your return, not from tax paid. The CRA's newcomers page says that from the date you become resident you report world income. On foreign income the CRA says, "Do not subtract the foreign taxes from your income"; the foreign tax is claimed as a credit against tax instead. A credit lowers your tax bill. It does not lower net income, which is the figure benefit formulas use.
That surprises many Nigerian households in Ontario: income already taxed at home still reduces the benefit, because the benefit measures resources, not who collected the tax.
The Ontario Trillium Benefit
Ontario's page (updated April 2026) describes the Trillium Benefit as three credits paid together. For the 2026 benefit year:
| Component | Maximum (2026 benefit year) |
|---|---|
| Ontario Energy and Property Tax Credit | $1,307 aged 18–64; $1,488 aged 65 or older |
| Northern Ontario Energy Credit | $189 single; $290 families |
| Ontario Sales Tax Credit | Up to $378 for each adult and child |
You must have lived in Ontario on 31 December 2025 and file your return by 30 April, with Form ON-BEN for the energy and property tax and northern energy credits. The CRA's Ontario programmes page says the sales tax credit is reduced by 4% of adjusted family net income over $29,047 for a single person with no children, or $36,309 for couples and single parents.
Worked example: the sales tax credit (illustrative)
| Single person, no children | Without Nigerian rent | With C$4,000 Nigerian rent |
|---|---|---|
| Adjusted net income | $30,000 | $34,000 |
| Amount over $29,047 | $953 | $4,953 |
| Reduction at 4% | $38.12 | $198.12 |
| Ontario Sales Tax Credit | $339.88 | $179.88 |
The C$4,000 of Lagos rent costs about $160 a year in this one credit, whether or not Nigeria taxed it. The energy and property tax credit has its own income test.
Which Nigerian items go into net income
- Rent from Nigerian property, after allowable expenses.
- Interest on naira or dollar deposits and Treasury bills, converted at the Bank of Canada rate on the day it arises.
- Dividends from Nigerian companies; the CRA notes foreign dividends do not get the dividend tax credit.
- Wages or fees for work done for a Nigerian employer or client.
- Gains on selling Nigerian land or shares, at the taxable portion.
For couples, the benefit looks at adjusted family net income, so your spouse's Nigerian income counts as well as yours. A spouse who owns a Lagos flat and reports the rent on their own return still adds it to the family figure.
The federal credit: now the Canada Groceries and Essentials Benefit
The CRA says the GST/HST credit was renamed the Canada Groceries and Essentials Benefit from July 2026, with the same eligibility. The last quarterly GST/HST credit payment was on 2 April 2026, with a one-time top-up on 5 June 2026. To qualify you must be resident in Canada in the month before and at the start of the payment month, and aged 19 or over or have a spouse or child. It is also calculated from adjusted family net income, so the same world-income rule applies. The CRA's pages set out current amounts.
Newcomers: the first-year statement of world income
If you arrived recently, the CRA's newcomers page asks you to report income earned outside Canada for up to two years before you became resident, even if it was nil, so it can calculate benefits; you are not taxed in Canada on that pre-arrival income. New residents without children apply for the federal benefit using Form RC151. See your first Canadian return and pre-arrival income.
Getting it right
- Report all Nigerian income on your return in Canadian dollars, at the Bank of Canada rate for the date received.
- Claim the foreign tax credit for Nigerian tax paid; do not net it off income.
- File by 30 April, with ON-BEN if you live in Ontario, even in a low-income year.

Where Pryme fits
Benefit calculations depend on accurate income figures. Naira rent received into the NGN balance of a Pryme account gives a dated record you can convert at the right rate for your return, and verifiable statements through our partner VerifyDoc.ai (receipts and statements) back up the figures.
Questions people ask
Does Nigerian income affect my Ontario Trillium Benefit?
Yes. The benefit uses adjusted family net income, which for a Canadian resident includes world income such as Nigerian rent or interest.
If I paid tax in Nigeria, does that income still count for benefits?
Yes. The Nigerian tax is claimed as a credit against Canadian tax; it does not reduce the net income that benefits use.
What happened to the GST/HST credit?
The CRA renamed it the Canada Groceries and Essentials Benefit from July 2026, with the same eligibility.
Do I need ON-BEN to get Trillium?
For the Ontario Energy and Property Tax Credit and the Northern Ontario Energy Credit, yes; file it with your return by 30 April.
