A Lagos-based graphic designer invoices foreign clients every month, pockets payments through a domiciliary account, and files nothing with the state revenue service. That arrangement stopped being invisible on January 1, 2026, when the Nigeria Tax Act 2025 and three companion laws took effect.
Under the new framework, self-employed individuals must self-declare annual income, calculate tax owed, and remit it without waiting for a demand notice. Taiwo Oyedele, then chairman of the Presidential Fiscal Policy and Tax Reforms Committee and now Nigeria’s Minister of Finance, put it plainly: “You are supposed to report yourself, calculate your tax, and pay if your income is above the threshold,” he told TechCabal.
Your self-employed tax bill is not one number; it is a stack of overlapping sole proprietor tax obligations in Nigeria covering income tax, withholding tax, VAT, and strict record-keeping.
Personal income tax rates sole proprietors face under new graduated bands
The headline change is a restructured personal income tax table with rates ranging from 0% to 25% across six brackets under the self-employment tax 2026 framework. The first ₦800,000 of taxable income carries a 0% rate, up from the previous ₦300,000 threshold, according to EY’s analysis of the Nigeria Tax Act.

Income between ₦800,001 and ₦3 million is taxed at 15%, while the ₦3 million to ₦12 million bracket carries an 18% rate. The ₦12 million to ₦25 million range attracts 21%, ₦25 million to ₦50 million is assessed at 23%, and only amounts above ₦50 million face the 25% ceiling, Africa Check confirmed.
These are marginal rates, meaning you pay the higher percentage only on income within each bracket. For a sole proprietor netting ₦10 million in annual profit, the effective rate lands well below 18% because lower bands absorb the first slices.
Deductions and reliefs that reduce your sole proprietor tax obligations in Nigeria
The law allows sole proprietors to subtract qualifying deductions from gross income before applying the graduated rates. The old Consolidated Relief Allowance has been replaced with a rent relief capped at the lower of 20% of annual rent paid or ₦500,000, though some analysts calculate the basis as 20% of gross income, Safeguard Global reported.
Pension contributions at 8% of gross income, National Housing Fund payments at 2.5%, and life assurance premiums capped at ₦100,000 remain deductible, Remote Solutions Africa noted. Business rent, salaries, utilities, marketing, transport, and interest on business loans also qualify.
Capital allowances on generators, vehicles, and computers let you spread major purchase costs across several tax years. Mixed personal and business expenses require clear apportionment, and the tax authority can reject claims lacking supporting receipts.
Withholding tax credits and how clients deduct from your invoices
Corporate clients deduct withholding tax before settling professional service invoices; the standard rate is 5% for individuals, NRS Portal Guide explained. That deduction is an advance payment on your annual income tax liability, credited at year-end filing.
Collect credit notes immediately after each payment, because clients may become unresponsive before you file, Aothr cautioned. If a supplier fails to provide a Tax Identification Number, the payer must deduct at double the standard rate.
VAT registration for sole proprietors above the ₦25 million turnover threshold
Value Added Tax at 7.5% applies to taxable goods and services, and any person making taxable supplies exceeding ₦25 million in any consecutive 12-month period must register, Taxly confirmed, citing Section 37 of the NTA 2025. The threshold is measured on revenue, not profit, and uses a rolling 12-month window.
Failure to register once turnover crosses that line attracts a ₦50,000 penalty for the first month and ₦25,000 for each subsequent month, plus back-owed VAT with 21% annual interest, SmartSMSSolutions reported. Once registered, you charge 7.5% on invoices, remit monthly to the Nigeria Revenue Service by the 21st, and offset input VAT.

- Personal income tax: graduated rates from 0% to 25% on net profit, filed by March 31 with your State Internal Revenue Service.

Books, records, and filing deadlines under the NTAA 2025
The Nigeria Tax Administration Act 2025 requires every taxable person to maintain financial and tax records for a minimum of six years, TaxNGR reported. That means keeping bank statements, invoices, and receipts for rent, utilities, salaries, and transport with clear transaction descriptions.
The annual personal income tax return deadline falls on March 31, covering earnings from the previous fiscal period. Section 101 of the NTAA sets penalties at ₦100,000 for the first month of default, and ₦50,000 for each month thereafter, BusinessDay reported.
“All of us must file our returns, including those earning low income. You must file returns by 31st March of the year in respect of the previous fiscal year.” Taiwo Oyedele, then chairman of the Presidential Fiscal Policy and Tax Reforms Committee, as reported by CrispNG via TomFlims.
Sole proprietorship versus incorporating: when each structure makes sense
Under the Nigeria Tax Act 2025, small companies with annual gross turnover of ₦100 million or less and fixed assets not exceeding ₦250 million qualify for 0% corporate income tax, PwC’s tax summary confirmed. That exemption also extends to capital gains tax and the new 4% development levy.
A sole proprietor earning ₦10 million in profit faces progressive personal income tax up to 18% on portions of that income, while an incorporated small company pays 0% CIT. The gap grows wider at higher income levels, Eko Solicitors noted.
However, the 0% CIT rate excludes companies providing professional services such as legal, accounting, and consulting practices, regardless of turnover. Incorporation also carries compliance costs including CAC registration, annual returns, mandatory audited financials, and complex NRS filing.
Enforcement has shifted, and sole proprietors need to act now
Nigeria has deployed AI-driven tools that cross-reference bank transactions, payroll records, and tax filings, and established information exchange agreements with over 100 countries. “If you earn money online, the number of platforms paying you isn’t many,” Oyedele told TechCabal, signaling intensified enforcement on digital earnings.
For sole proprietors above the ₦800,000 tax-free threshold, the practical path starts with obtaining a Tax Identification Number linked to your NIN. If your annual profit consistently exceeds ₦10 million and you do not provide professional services, consulting a tax adviser about incorporation could yield meaningful savings.
