Common questions

Which tax year should I use when checking a rule?
Use the tax year of the income or transaction, not only the calendar year when you file. Confirm that every threshold, form and instruction applies to that same tax year.
Does a tax calculator replace a tax return?
No. An educational calculator models selected federal rules and stated inputs. It may exclude state tax, special elections, phaseouts, additional forms and facts that change the final return.
Where should I verify a U.S. federal tax claim?
Use the current IRS form instructions, publication or topic page that governs the issue. For unresolved account problems, the Taxpayer Advocate Service may be able to help.
