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 Canadian and Nigerian law both treat you as resident, Article 4 of the Canada–Nigeria agreement settles it with tests applied in order: where you have a permanent home; if both, where your centre of vital interests is; if that is unclear, where you have a habitual abode; then nationality; and finally agreement between the two tax authorities. Many Nigerians in Canada meet both countries’ rules, because Nigeria’s 2025 law counts a permanent home or family ties as enough.
Why dual residence is common
Each country first applies its own law. In Canada, the CRA looks at residential ties: a home, a spouse or common-law partner, and dependants are the significant ones, with secondary ties such as a driver’s licence, bank accounts and provincial health cover (CRA guide T4131). In Nigeria, PwC’s summary of the Nigeria Tax Act 2025 says you are resident if any one of these applies: domicile in Nigeria, a permanent home available for your domestic use, habitual abode, 183 days or more in any 12-month period, substantial economic or immediate family ties, or service as a Nigerian diplomat abroad.
So a nurse in Edmonton who keeps her Lekki flat furnished for visits, or an engineer whose wife and children have not yet joined him in Ottawa, can be resident in both countries under their own laws. That is where the treaty steps in.
The tests in Article 4, in order
- Permanent home. You are resident where you have a permanent home available to you. If you have one in only one country, that decides it.
- Centre of vital interests. If you have a permanent home in both, you are resident where your personal and economic relations are closer: family, job, business, social life, assets.
- Habitual abode. If the centre of vital interests cannot be determined, or you have a permanent home in neither, you are resident where you habitually live, judged by time actually spent.
- Nationality. If you have a habitual abode in both or neither, you are resident in the country of which you are a national.
- Mutual agreement. If you are a national of both or neither, the tax authorities settle it between them.
For a company resident in both, the agreement deems it resident where it is incorporated.
How the tests play out
| Your situation | Likely treaty result |
|---|---|
| Family and job in Canada; Lagos house rented out to tenants | Canada: the rented house is not a home available to you |
| Family and job in Canada; Lagos flat kept empty for your use | Permanent home in both, so centre of vital interests, likely Canada |
| Job in Canada; spouse and children still in Nigeria; homes in both | Vital interests split; may come down to habitual abode |
| Long stays in both, homes in both, family split | Possibly nationality; a dual citizen may need mutual agreement |
These are illustrations of how the order works, not rulings. The facts are weighed together, and the same person can get a different answer in different years.
What the result changes
The tie-breaker decides which country is your residence for the treaty. The other country then taxes you only as it would a non-resident under the treaty, broadly on income arising there. If Canada wins, Nigeria should tax only Nigerian-source items such as rent on Nigerian property, and Canada taxes your world income with a credit for that Nigerian tax under Article 23. If Nigeria wins, Canada should, under the treaty, tax you broadly as it would a resident of Nigeria. That has knock-on effects for your Canadian filing, benefits and withholding, so take advice before relying on it.
For a Nigerian salary while living in Canada, the result feeds into Article 15. See remote work for a Nigerian employer, and for a long visit home, Nigerian residency after 183 days.
When the two authorities disagree
Article 25 lets you ask the tax authority of the country where you are resident to take up a case of taxation not in line with the agreement. The request must be made within two years of the first notification of the action causing it. In Canada the request goes to the CRA; in Nigeria, to the federal tax authority. Keep the dates of any assessment letter from either side.
Evidence that helps
If either authority questions your residence, you will be asked to show the facts behind each test. Useful records are a lease or title for each home and whether it was let to tenants, a travel log or passport stamps for days in each country, where your children are at school, your employment contract and where you do the work, and where your bank accounts, investments and professional memberships sit. Gather them as you go; rebuilding a travel history years later is hard.
What to check first
- Is a home in Nigeria available to you, or rented out on a lease?
- Where do your spouse and children live?
- Where is your main job or business?
- How many days did you spend in each country this year and last?
- Which passports do you hold?
Write the answers down each year. If you are leaving Canada for good, the CRA’s form NR73 is the way to ask its view; see filing NR73 when moving to Nigeria.
Where Pryme fits
Ties are partly financial. Keeping Nigerian and Canadian money in one multicurrency account, with verifiable statements from VerifyDoc.ai, gives you a clear record of where your economic life sits if either authority asks.
Questions people ask
Can I be tax resident in both Canada and Nigeria?
Yes, under each country’s own law. The Canada–Nigeria agreement then uses the Article 4 tie-breaker to give you one treaty residence.
Does keeping a house in Lagos make me Nigerian tax resident?
Under the Nigeria Tax Act 2025, as summarised by PwC, a permanent home available for your domestic use is one of the residence tests. A house let to tenants is not available to you in the same way.
What is the centre of vital interests?
The country where your personal and economic relations are closer: family, work, business, assets and social life.
What if both countries still tax me?
Under Article 25 you can ask your tax authority to resolve it with the other, within two years of the first notice of the action.
