How much should I pay in quarterly estimated taxes for 2025?
Plan 2025 or 2026 quarterly estimated tax payments based on net profit and other income. The tool estimates self-employment and income tax, then divides payments using either the 90% current-year method or the IRS safe-harbor rules. Use seasonal weighting if income is uneven.
How this calculation works
- Calculates SE tax and income tax from net profit and deductions.
- Applies either 90% of current-year tax or the prior-year safe-harbor rule.
- Splits remaining payments into equal or seasonal quarters.
Common mistakes and caveats
- Safe-harbor thresholds depend on prior-year AGI.
- Income changes during the year can require recalculating payments.
- State estimated taxes are not included.
FAQ
What is the safe-harbor rule?
It generally means paying 100% (or 110% for higher AGI) of last year's tax to avoid penalties.
