TaxC is a Nigerian tax platform covering both personal and business tax. For individuals, there's a Personal Income Tax calculator, a Tax Tracker, and Ada Pro for AI-powered guidance. For business owners, TaxC for Teams adds a Company Income Tax calculator, payroll & PAYE tracking, and Ada — your AI business advisor.

For individuals, TaxC calculates Personal Income Tax (PIT) based on Nigeria's 2025/2026 Nigeria Tax Act (NTA) rules — salary, self-employment, rental, and investment income, factoring in deductions like pension contributions and rent relief (up to ₦500,000).

For businesses, TaxC for Teams calculates Company Income Tax (CIT), the 4% Development Levy, and employee PAYE across your whole payroll.

According to the Nigeria Tax Act (NTA) 2025, personal income tax is paid by any individual who is deemed a resident of Nigeria (typically determined by physical presence for 183 days or more within a 12-month period) and whose annual income exceeds the ₦800,000 exemption threshold.

TaxC for Teams (₦12,000/month) is our business tax suite: a Company Income Tax calculator, payroll & PAYE tracking with CSV import for your employee list, Business Insights with "what if" scenarios, calculation history, and a downloadable PDF summary or payroll CSV export. It also includes personal Ada Pro access at no extra cost.

Try TaxC for Teams

Ada is the free assistant available across the site for quick personal tax questions.

Ada Pro (₦3,500/month) is a dedicated chat assistant for deeper personal tax guidance — it can search the web for current information and read images or PDFs you upload (payslips, assessments, portal screenshots).

Ada for Teams is built into TaxC for Teams — she reads your live calculator and payroll figures directly, gives specific observations about your business's tax position, can search the web, and can also read attached images or PDFs like invoices or asset registers.

Yes — on TaxC for Teams, the payroll tab has an "Import CSV" button. Upload a CSV with employee names and salaries and TaxC will map the columns automatically and show you a preview before adding anyone, so you can check it looks right first.

On TaxC for Teams, your company figures and payroll are saved automatically once you're logged in, and every calculation is kept in your history so you can look back at past runs. You can also download a PDF summary of your business tax position or export your payroll as a CSV, both included free with your subscription.

For individuals, TaxC lets you input deductions like pension contributions and annual rent paid. Rent relief is calculated as 20% of your rent, capped at ₦500,000. These reduce your taxable income, lowering your tax liability. Other deductions may include life insurance, NHF, etc.

Withholding Tax (WHT) is a tax deducted at source on certain incomes, like rental income (10%) or investment income (10%). TaxC lets you input WHT paid, which is credited against your final tax liability to avoid double taxation.
