Tools
Six tools that do the arithmetic and the sorting for you. Each one shows its working, and none of them ask who you are.
Every figure these tools produce is an estimate built from published IRS rates and rules, not a determination. Nothing you enter is sold, and no result is a referral to anyone.
IRS Notice Action Plan
You have a notice in hand and need to know what happens next.
Choose the notice you received, enter the date printed on it, and get a plain-language action plan with the deadline added to your calendar and fixed email reminders.
Penalty and Interest Estimator
You want to know what the penalties are costing you, and whether relief exists.
Estimate failure-to-file and failure-to-pay penalties plus interest, then review the IRS rules for automatic, first-time, and reasonable-cause relief.
Payment Plan Estimator
You can pay something every month and need to see which plan fits.
Compare short-term and long-term installment agreements: monthly payment, setup fee, and what the balance does over the life of the plan.
Offer in Compromise Estimator
You want to understand how an offer amount is calculated before filing one.
Organize the figures Form 656 asks for and see how the IRS arrives at reasonable collection potential.
Resolution Quiz
You do not yet know which option applies to you.
Seven questions that map your answers onto the resolution routes the IRS actually offers, with the reasoning shown rather than hidden.
Transcript Chooser
You have been told to get a transcript and there are five kinds.
Match your task to the transcript that holds the record you need — return, account, record of account, wage and income, or proof of non-filing.
