Quarterly tax estimate (educational)

Simplified learning math only — ignores income-tax brackets, credits, and non-US rules.

Educational estimate · Not tax advice · No signup

Not tax, legal, or accounting advice. Estimates are educational only and may be wrong for your situation. Rules vary by location and change over time. Confirm with a qualified professional and the IRS estimated taxes page (or your local tax authority).

Your numbers (you enter them)

Rough profit after business expenses — not gross sales. Use your books or a CPA worksheet; this field is not prepared for you.

This tool applies a simplified US self-employment tax illustration (~15.3% on ~92.35% of net earnings) and divides by four. It does not include income tax brackets, deductions, credits, prior-year safe harbors, or state tax.

Read the official IRS estimated taxes page and talk to a qualified professional before sending any payment.
