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
If you are resident in Canada and rent out a flat in Lagos, you report the rent on Form T776 and can deduct reasonable expenses of earning it, including repairs and maintenance (line 8960). The CRA's rental guide draws the line between a current expense, which restores the property to its original condition and is deductible in the year, and a capital expense, which improves it beyond that condition or gives a lasting benefit and must be claimed over time through capital cost allowance. Keep receipts, contracts and proof of payment for six years from the end of the tax year.
A flat in Yaba, Lekki or Surulere earns rent; it also needs a new pumping machine, a repainted stairwell, a fixed roof leak after the rains. If you live in Canada, the rent is part of your worldwide income, and the costs of keeping the flat rentable can reduce the tax on it. The question every landlord abroad asks is which of those costs go on this year's return. This article applies the CRA's Rental Income guide (T4036, modified 27 March 2026) to a Lagos flat.
Repair or improvement: the test that decides
T4036 sets out how the CRA tells a current expense from a capital one:
- Current expenses recur and give a short-term benefit; capital expenses usually give a lasting benefit.
- Restoring a property to its original condition is generally current; improving it beyond its original condition is generally capital.
- Replacing a separate asset, such as a refrigerator, is capital. Repairing part of the building, such as rewiring, is usually current.
- Repairs made to get a newly bought used property into rentable condition are generally capital.
| Lagos flat expense (examples) | Likely treatment under T4036's tests |
|---|---|
| Fixing a roof leak with like-for-like sheets | Current: restores original condition |
| Repainting between tenants | Current: maintenance |
| Repairing burst plumbing | Current |
| Replacing a broken split air conditioner | Capital: a separate asset |
| Buying a new generator or inverter for the block | Capital: a separate asset |
| Adding a boys' quarters or an extra floor | Capital: an improvement |
| Tiling and rewiring a flat you just bought before first letting | Capital: preparing a used property for rent |
The table applies the guide's tests to common cases; your facts decide. Capital items are not lost: they go into capital cost allowance, explained in claiming depreciation on a Nigerian rental.
Other expenses you can claim on T776
T776 lists the deductible rental expense lines. For a flat in Lagos the relevant ones are usually:
- Repairs and maintenance (8960)
- Labour and materials paid to others. T4036 says the value of your own labour is not deductible.
- Management and administration fees (8871)
- Fees to an agent or caretaker for finding tenants or collecting rent.
- Property taxes (9180)
- For Lagos, the Land Use Charge on the property.
- Insurance (8690)
- Building insurance on the rented flat.
- Interest and bank charges (8710)
- Interest on money borrowed to buy or improve the rental.
- Professional fees (8860)
- Legal or accounting fees for the rental, such as drafting a tenancy agreement.
- Utilities (9220)
- Only if you, not the tenant, pay them.
- Travel (9200)
- T4036 allows travel to collect rents, supervise repairs and manage your properties.
Travel is the expense to handle carefully. A December trip home that is mostly family time is not a rental expense because you also checked on the flat. If you claim part of a trip, be ready to show the rental purpose and how you split the cost.
Converting naira and dealing with Nigerian tax
Report the rent and each expense in Canadian dollars. The CRA's general guide says to convert foreign amounts at the Bank of Canada rate in effect on the day the amount arises, with other sources or an annual average accepted in some cases. Use one consistent method and keep the rate you used for each item.
If you paid Nigerian tax on the rent, you do not deduct it as an expense; the CRA's line 12100 guidance says to claim a foreign tax credit rather than subtract foreign tax from income. How Nigeria taxes the rent is covered in the Nigerian library's guide to tax on rental income in Nigeria, and how the credit works in Lagos rental tax and the Canadian credit.
Worked example (illustration only)
Example: a two-bedroom flat earns ₦6,000,000 rent in a year. The caretaker's 10% fee is ₦600,000, painting and plumbing repairs cost ₦450,000, and Land Use Charge is ₦150,000. Deductible current expenses total ₦1,200,000, leaving net rent of ₦4,800,000 before capital cost allowance. Each figure is converted to Canadian dollars at the rate for its date. A new air conditioner bought the same year for ₦900,000 is not in the ₦1,200,000; it is a capital item.
Records the CRA expects
T4036 says to keep invoices, receipts, contracts and other supporting documents, not to send them with your return, and generally to keep them for six years from the end of the tax year they relate to. For a flat run from Canada, that means:
- A written tenancy agreement and rent receipts.
- Written invoices from artisans and suppliers, even if they are informal businesses.
- Proof of payment for each expense: bank transfer records, not cash where you can avoid it.
- The caretaker or agent's statement of rent collected and money spent.
- Land Use Charge bills and receipts.
- Your currency conversion working.
If the flat is jointly owned, each owner reports their share of income and expenses; T4036 deals with co-owners. If the flat's cost is over $100,000, it is also reportable on Form T1135; see Nigerian land and the T1135.
Where Pryme fits
Paying artisans and caretakers by transfer leaves a trail. From a Pryme Personal account you can send naira to a Nigerian account, with the rate and fee shown before you approve, and generate a verifiable receipt through VerifyDoc.ai for each payment, useful for the six-year file.

Questions people ask
Can I deduct repairs on my Nigerian property from Canadian tax?
Yes, if the property is rented out and the repair restores it to its original condition. Report rent and expenses on Form T776 in Canadian dollars.
Is a new generator for my Lagos flat a repair or a capital expense?
Under the CRA's tests, replacing or adding a separate asset is capital, so a generator goes into capital cost allowance rather than repairs.
Can I claim my flight to Nigeria as a rental expense?
Only travel to collect rent, supervise repairs or manage the property. A family trip with a quick inspection is hard to justify; keep evidence if you claim a share.
How long should I keep receipts for my Lagos rental?
Generally six years from the end of the tax year they relate to, per CRA guide T4036.
