How to use NigTax 2026
This guide walks through the calculator on the home page: business tax estimates and personal income tax (PIT) from your statements.
1. Choose your mode
Use the top menu: Business Entity for company-style turnover and taxes, or Personal Income for individual PIT with reliefs and bands.
2. Enter your details
Fill in the form (business name, RC/TIN where relevant, or personal name and income). Email fields are optional unless you need them for your own records.
3. Upload your statement (optional but recommended)
- Drag and drop a file into the upload area, or click Browse Files.
- Supported types: Moniepoint or OPay exports as Excel (.xlsx, .xls), CSV, or PDF.
- If the PDF is password-protected, enter the password in the field provided.
- You can combine upload with a manual turnover figure if you need to override or supplement parsed totals.
4. Adjust assumptions (business)
Use the Declared Taxable Profit Margin slider to set the percentage of inflows treated as profit. That gives gross profit for the estimate.
Then use Allowable deductions (CIT) to enter annual ₦ amounts you treat as allowable under the Nigeria Tax Act (e.g. salaries, business rent, loan interest, employer pension, capital allowances, other allowable expenses). They reduce gross profit toward assessable profit. If the total deductions exceed gross profit from your margin, the tool scales them down for this estimate.
5. Reliefs and deductions (personal)
Enter rent, pension, NHF, NHIS, and life assurance where they apply. The tool applies consolidated relief and statutory deductions before computing PIT bands.
6. Generate the assessment
Click Generate Assessment. Review inflows, outflows, profit or taxable income, and the tax breakdown on the right.
7. Download your report
When the run succeeds, use Download Report to save a PDF summary. Reset clears the current session inputs when you want to start over.
NigTax PRO (optional)
PRO members can subscribe via the menu, sign in, use multiple statement rows in one assessment, and save queries to reload or regenerate PDFs later. Open Recent reports after login to manage saved assessments.
Certified consultant (add-on)
After you have a completed assessment, Get certified consultant to review & sign starts a paid flow: a registered tax consultant can review your figures and apply stamp and signature according to admin settings. Fees and availability are shown in the modal.
Important: NigTax 2026 is an assessment aid, not a substitute for professional advice or official filings. Always verify results against current law and your accountant or the tax authority.
