Questions & answers
Short answers about NigTax 2026. For steps, see How to use.
What is NigTax 2026?
A browser-based calculator that helps estimate Nigerian business and personal income tax from typical Moniepoint or OPay statement exports, with optional PDF reports.
What are the business “allowable deductions” fields?
They are optional inputs for common Companies Income Tax deduction categories (salaries, rent, interest, pension, capital allowances, other lump-sum allowable costs). The law requires expenses to be wholly and exclusively for the business. The calculator subtracts what you enter from gross profit (turnover × your margin), and scales the total if it exceeds that profit. It is a planning aid only.
Which file formats work?
CSV, Excel (.xlsx, .xls), and PDF statements from supported providers. If a PDF asks for a password when you open it, enter the same password in the tool.
Is this official advice from FIRS or the government?
No. Outputs are estimates for planning and education. Filing obligations, audits, and final assessments are determined by law and the relevant authorities. Consult a qualified tax professional for filing decisions.
Do I need an account to use the calculator?
The basic calculator works in the browser without signing in. NigTax PRO is optional: it adds saved queries, multi-statement rows, and related features tied to your membership account.
What does PRO membership include?
PRO lets you sign in, stack multiple statements in one run, and save assessments to reload or regenerate PDFs later. Use PRO membership and PRO login in the menu; pricing and payment run through the linked checkout experience.
What is the certified consultant option?
A paid add-on: a registered tax consultant may review your assessment and apply an official stamp and signature, subject to admin configuration and availability. It does not replace your own duty to ensure accuracy.
Where does my data go?
See our Privacy Policy for what is processed, why, and retention at a high level. Avoid uploading files you do not need for the estimate.
Why are my totals wrong or empty?
Check that the file matches supported layouts, dates, and columns. Try exporting again from your bank app. For PDFs, ensure the password is correct. Manual turnover can be used if parsing misses part of your activity.
