Terms of Use

By using MyTaxQuarter, you agree that the site is provided for informational and educational purposes only. It is intended to help freelancers and independent contractors think through estimated tax planning, not to prepare or file a tax return.

Not professional tax advice

MyTaxQuarter is not a substitute for professional tax, legal, accounting, or financial advice. Tax outcomes depend on your full facts, including deductions, credits, household income, state rules, local taxes, business structure, retirement contributions, and prior-year filings.

No penalty guarantee

We are not responsible for underpayment penalties, interest, filing errors, missed deadlines, or decisions made based on calculator results. You are responsible for reviewing payment amounts, payment deadlines, tax forms, and agency instructions before making federal or state payments.

Data accuracy disclaimer

We work to keep tax constants and explanations accurate, but tax laws, IRS guidance, state rules, and administrative interpretations can change. The calculator may omit credits, deductions, local taxes, alternative minimum tax, net investment income tax, special business rules, and other items that affect your return.

Use at your own discretion

Use MyTaxQuarter as a planning aid and confirm important decisions with official IRS resources, state tax agencies, tax software, or a qualified tax professional.
