If you work for a Nigerian Company: Your employer is legally mandated to calculate and deduct your Personal Income Tax (PAYE) from your monthly salary before paying you. At the end of the year, you must still file a Self-Assessment Return. If your employer calculated correctly, your tax balance will be ₦0.00. You generally only pay a ‘balance’ if you have extra income (from freelancing or side-business profits) that your employer did not tax.
If you earn from a Foreign Company (Remote Work/Freelancing): Your foreign employer cannot deduct Nigerian tax for you. You are now legally required to:
Gifts and inheritances are tax exempt — If your father passes away *God forbid* and leaves you a house in Ikoyi, or your aunt gifts you ₦5 million cash for your wedding, the government takes ₦0.00 from that transaction. However, if you now receive rental income for the house, you will pay tax on that. If you decide to sell the gift/inheritance later, you pay tax on the profit.
