Estimated Taxes
Calculate quarterly estimated tax payments and clear IRS safe-harbor thresholds without the year-end surprise.
Overview
Estimated Taxes helps controllers and finance teams size each quarterly estimated payment so you stay inside the IRS safe-harbor rules (110% of prior-year liability or 90% of current-year). It tracks income and withholding as the year progresses and shows exactly what to remit before each 1040-ES / 1120-W due date. No more eyeballing the number and hoping you dodge the underpayment penalty.
The problem
Finance teams guess at quarterly estimated tax payments and risk underpayment penalties or overpaying and tying up cash.
How it works
You enter projected income, withholding, and prior-year liability, and the tool computes each quarter's required payment against the safe-harbor and annualized-income thresholds, flagging shortfalls before the due date.
Use cases
- Sizing Q1-Q4 estimated payments to hit the prior-year safe harbor and avoid underpayment penalties
- Recalculating mid-year when income shifts so cash isn't over- or under-remitted
- Tracking cumulative withholding and payments against each 1040-ES / 1120-W due date
