Calculate safe-harbor quarterly tax payments from your actual tracked profit, with due-date reminders, instead of estimating off gut feel.
Backed by a 30-day money-back guarantee. If it is not useful, we will refund it, no questions asked.
Business owners underpay quarterly taxes because they estimate off gut feel instead of actual profit. This planner starts with your year-to-date net profit and your blended estimated tax rate, federal, state, and self-employment, for each quarter, and calculates your safe-harbor payment due from your actual tracked profit, not a guess.
Log what you actually paid, and Payment Status flags UNDERPAID if it's short of the calculated safe-harbor amount. Days Until Due counts down to each IRS quarterly deadline so payments never sneak up on you, and you update YTD profit each quarter as your bookkeeping closes, keeping every payment grounded in real numbers.
We've heard from business owners who paid the same rough number every quarter regardless of how the year was actually going, and got hit with an underpayment penalty when profit came in higher than expected. Calculating from tracked profit instead of a flat guess is what closes that gap before the IRS does.
