- 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.
