Four calculators, built so you know your own numbers before anyone else tells you what they are.
A lot of "tax relief" marketing starts with a scary number and ends with a phone call. IRSReliefGuide starts from the other direction: run your own figures first, in your browser, and decide what to do from there.
Most people who owe the IRS money never see a plain breakdown of what is actually accruing, principal, penalties, and interest, before a relief company gives them a quote. This site was built to close that gap: four calculators that show your real running numbers, plus guides that explain the IRS's own programs in language that does not require a law degree.
The tax debt calculator totals what you owe once penalties and interest are added in. The offer in compromise calculator gives a rough read on the IRS's reasonable-collection-potential formula. The payment plan calculator projects a monthly installment figure. The penalty and interest calculator separates the failure-to-file charge from the failure-to-pay charge, since they are not the same thing and do not accrue at the same rate.
Every formula traces back to a published IRS rule, the Internal Revenue Code section covering the penalty, a current interest rate table, or an installment agreement threshold posted on IRS.gov. The editorial standards page covers how those figures get checked and updated. Nothing you type into a calculator is sent to a server or stored; the math runs on your device and stays there.
IRSReliefGuide is not a law firm, a CPA practice, or the IRS, and using a calculator here does not create any kind of professional relationship. The results are estimates built from general rules, not a determination of what you specifically owe. If a number here matters, a licensed tax professional can confirm it against your actual account.
