Your own notice governs

Where a deadline matters, work from the date printed on the notice you actually received, not from anything here. IRS notice pages frequently state no number of days at all, and a figure you find elsewhere may not apply to your notice, your tax period or your circumstances.

We do not predict outcomes

Nothing here states or implies that you qualify for a programme, that the IRS will accept an offer, that a penalty will be removed, or how much you might save. Those are determinations the IRS makes on facts we do not have.

The calculators produce arithmetic estimates from the numbers you type in. An estimate is not an IRS determination, and where a calculation relies on an assumption of ours rather than a published IRS figure, the page says so.

How pages are sourced

Pages cite the IRS material behind them, with the date we retrieved it. Where the IRS does not publish something, we say that rather than filling the gap — several pages carry a “what this page does not say” section for exactly that reason.

Pages are sourced to primary IRS materials and editorially reviewed. They are not reviewed by a tax professional. Some older pages predate this standard and do not yet cite a source; those say so on the page.

Things change

Thresholds, fees, penalty rates and interest rates are revised, some of them annually or quarterly. Where a figure is dated we show the year it applies to. Check the current IRS page before acting on any number.

Tell us if we are wrong

If you find an error, we want to hear about it and we will correct it. Report a correction.
