How to use NigTax 2026

This guide covers the latest workflow: a fast simple mode for everyone, plus optional Advanced · PRO controls if you need deeper accuracy.

1. Choose your mode

Use the top menu: Business Entity for CIT-style estimates, or Personal Income for PIT.

2. Fill only what you need

Business and personal forms are intentionally lightweight. Core fields are enough to run an estimate. Email and many profile fields are optional.

3. Upload statement(s) (recommended)

  1. Drag and drop, or click Browse Files.
  2. Supported types: Excel (.xlsx, .xls), CSV, and PDF.
  3. For password-protected PDFs, enter the same password you use in your banking app.
  4. Non-PRO users can run a single statement; PRO supports multi-statement workflows and saved reports.

4. Run simple mode first

For business, set your profit margin. For personal, enter gross income and any normal reliefs/deductions you know. Then click Generate Assessment.

5. Optional: open Advanced · PRO

If you are a PRO user, open the Advanced · PRO dropdown only when needed. Leave it closed for the simple flow.

  1. Business PRO: allowable CIT deductions, turnover adjustments, declared gross profit override, prior-year loss, WHT/CIT instalments, period notes, and accountant export (JSON/CSV).
  2. Personal PRO: other income, other reliefs, WHT, period notes, and accountant export (JSON/CSV).
  3. All advanced fields are optional. Blank fields are treated as zero or not applied.

6. Review the right-side results

Check inflows, outflows, assessable/taxable profit, and tax breakdown. PRO-only rows appear only when relevant values are provided.

7. Download report and reset when done

Use Download Report for PDF. Use Reset to clear your current run and start fresh.

NigTax PRO (optional)

PRO adds multi-statement support, saved queries, PDF regeneration, optional advanced assumptions, and accountant handoff exports. Access via PRO membership, PRO login, and Recent reports in the top navigation.

Certified consultant (add-on)

After an assessment, click Get certified consultant to review & sign to start the paid review flow. Fees and availability are shown inside 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.
