Turn Life Events Into a
Canonical Tax Story

Traditional tax experiences ask you to fill forms that mirror law, not life. Blackgoat flips that. We start with who you are and how you live.

Who You Are

Your state, local area, employment status, age, and tax year. These define the context of your tax obligation.

How You Earn

Salary, side gigs, informal business, investments, and more. We treat these as a continuous stream of events.

How You Live

Rent, pension contributions, health insurance, and major asset sales. These are the life events that drive reliefs and exemptions.

What is Withheld

PAYE from your employer, withholding tax, and past payments. We track these as they happen, not at the end of the year.

The Power of the Story

Behind the scenes, the app turns this into a single, structured description of your tax position—a canonical story of your year that the tax engine can understand.

Quick Forecasts

"If I change jobs, what happens to my tax?"

Annual Filings

"Use my saved income streams to file this year."

Future Products

"Can I qualify for a loan based on my verified tax history?"

Map Your Life onto the Law

Instead of starting from tax law and forcing people to adapt, Blackgoat starts from people's lives and maps that onto the law.

If you have a standard Personal Income Tax (PIT) return only (Salary/Employment income, and common reliefs such as Pension, NHF, NHIS, and Life Assurance), you can file seamlessly with Blackgoat Basic. Roughly 65% of Nigerian taxpayers are eligible for this standard filing category.

Examples of situations included in a Standard PIT Return:

  • Employment Income (PAYE) from one or more employers
  • Interest and Dividends (where WHT is final tax)
  • Consolidated Relief Allowance (CRA)
  • Pension Contributions (RSA)
  • National Housing Fund (NHF) Contributions
  • National Health Insurance Scheme (NHIS) Contributions
  • Life Assurance Premiums
  • Business Expenses (for specialized Self-Employed filings)

Blackgoat Advanced (for situations not included in Standard Return):

  • Complex Capital Gains adjustments
  • Foreign Income with double taxation treaty claims
  • Complex Trust or Estate income
  • Business Income requiring audited financial statements
