Questions

When are federal estimated tax payments due?

The calendar lists the four Form 1040-ES dates the tool uses (April, June and September of the tax year and January of the next), moved to the next business day when one falls on a weekend or a federal holiday. Confirm them against the IRS instructions for your year.

Are the state sales tax dates reliable?

They are presets, several read from the state's own page and the rest from search excerpts and third-party guides. Your filing frequency and your state's notice decide your real date, so check it. States with no general sales tax get a note instead of dates.

Is my information uploaded?

No. The dates and the file are made in your browser. Anonymous feature events (calendar_shown, calendar_downloaded) are counted only in local storage on your device; Do Not Track and Global Privacy Control are honoured.
