Keep more of your hard-earned money. Every naira you spend running your business is money that should not be taxed. But many small business owners pay more tax than necessary simply because they do not know what expenses they can deduct. Tax deductions reduce your taxable profit. Lower profit means lower tax.
This guide is your complete cheat sheet for small business tax deductions in Nigeria. Use it to track your expenses throughout the year and share it with your accountant at tax time.
What Is a Tax Deduction?
A tax deduction is an expense you can subtract from your business income before calculating your tax. The formula is simple:
Business Income – Allowable Expenses = Taxable Profit
You pay tax on the taxable profit. Every legitimate business expense you claim reduces your tax bill. But there are rules. Expenses must be incurred wholly, exclusively, and necessarily for your business. They cannot be personal expenses disguised as business costs.
Categories of Tax Deductions
Here are the major categories of expenses you can deduct. Keep receipts for every single one.

If you sell to customers on credit and they do not pay, you can deduct the unpaid amount as a bad debt. You must show you have tried to recover the money.
14. Depreciation
Large assets like machinery, computers, vehicles, and furniture are not fully deductible in one year. Instead, you deduct a portion each year over the asset’s useful life. This is called depreciation. The Nigerian tax law sets specific rates for different asset types.
Common depreciation rates:
-
Computers and office equipment: 25% per year
-
Furniture and fittings: 10% per year
-
Motor vehicles: 25% per year
-
Plant and machinery: 10% to 15% per year
15. Capital Allowances
Nigeria’s tax law also provides capital allowances, which are similar to depreciation but often more generous. For small businesses, the annual investment allowance allows you to deduct a percentage of qualifying capital expenditure in the year of purchase. Consult your accountant to maximise these.
What You Cannot Deduct
Some expenses are not deductible, no matter how business-related they feel:
-
Personal expenses (clothing, personal meals, personal travel)
-
Drawings (money you take for yourself)
-
Fines and penalties
-
Political contributions
-
Gifts (generally limited or not deductible)
-
Capital invested in the business
Record Keeping Essentials
To claim deductions, you must have proof. Keep these records:
Receipts. Keep every receipt for every business expense. Digital photos of receipts are acceptable.
Invoices. Keep copies of invoices you receive from suppliers.
Bank Statements. Use a separate business bank account. This makes tracking expenses much easier.
Mileage Log. If you use a personal vehicle for business, keep a log of dates, destinations, and purposes.
Contracts. Keep copies of contracts with suppliers and clients.
The tax authorities can audit your returns for up to six years. Keep your records that long.
How to Maximise Your Deductions
Use a Separate Business Account. Mixing personal and business expenses makes tracking deductions nearly impossible. Open a dedicated business account.
Record Expenses Immediately. Do not wait until tax time. Record expenses as they happen. Your memory will fail you.
Talk to Your Accountant Early. Do not wait until the filing deadline to ask what is deductible. Review your expenses with your accountant quarterly.
Prepay Expenses. If you have cash at year’s end, consider prepaying expenses for the next year. Rent, insurance, and subscriptions can be prepaid and deducted in the current year.
Time Large Purchases. If you plan to buy equipment, consider timing it to maximise tax benefits in high-profit years.
Frequently Asked Questions (FAQ)

A2: Yes, but only the portion used exclusively for business. Calculate the percentage of your home used for business and deduct that percentage of rent, utilities, and security.
Q3: Can I deduct meals with clients?
A3: Meals with clients are generally deductible if they are directly related to business discussions. Keep records of who you met and what was discussed.
