What is EZFile?

EZFile is a Claude Code plugin that helps single W-2 filers calculate their federal tax return and file for free at Free File Fillable Forms. Named after the discontinued IRS Form 1040-EZ, which served exactly this demographic before the IRS retired it in 2018. Upload your W-2, answer a few questions, and get a complete Form 1040 calculated line by line — all processed locally on your machine with full privacy protection.

Who This Is For

EZFile is designed for straightforward tax situations:
  • Single filer (not married)
  • No children or dependents
  • W-2 wage income only (no freelance, 1099s, investments)
  • Renter (no mortgage or property tax)
  • May have federal student loans (1098-E)
  • Tax Year 2025
If your situation is more complex, EZFile will tell you and recommend a CPA or full-service tax software.

Key Features

Privacy & Security

EZFile is designed with privacy as a core principle:
  • Local only: All processing happens on your machine. Tax data never leaves your computer.
  • SSN masking: Full SSNs are never stored or displayed. Only the last 4 digits are shown.
  • Network blocking: Hooks prevent any network commands (curl, wget, etc.) from running.
  • PII protection: Hooks block SSN/EIN patterns from appearing in web searches.
  • Output scanning: Written files are scanned for accidentally exposed SSNs.
Disclaimer: EZFile is a tax calculation assistant, not a licensed tax preparer or tax advisor. It does not file your taxes — you must file yourself at freefilefillableforms.com or another IRS-approved method. Review all numbers carefully before entering them. You are responsible for the accuracy of your tax return. For complex situations, consult a CPA or enrolled agent.
