Filing Status Decision Tree — Step-by-Step Guide for Tax Preparers

Filing status is the first decision that shapes everything else on a return — the standard deduction, the tax brackets, credit eligibility, and more. But it's not always obvious, especially with single parents, newly separated couples, dependents who live in two households, or clients who don't know the rules. Getting it wrong isn't JUST a small mistake.

The 2026 Filing Status Decision Tree gives you a clear, step-by-step guide to determining the correct filing status for any client scenario — Single, MFJ, MFS, Head of Household, or Qualifying Surviving Spouse. Follow the decision path, document your determination, and move forward with confidence knowing the foundation of the return is correct.

Never guess a client's filing status again.
