Understand your rights.

Official starting points for understanding the tax process, finding free assistance, and learning about review and appeal routes.

If you received a notice, identify its number, tax period, requested action and exact deadline. Different procedures have different deadlines; a general website cannot determine yours.

Read before you respond.

Does a filing extension also extend the payment deadline?

A normal extension to file does not extend the time to pay. Estimate and pay the amount due by the original payment deadline. Special disaster, combat-zone or other relief may operate differently, so check the specific relief and tax period rather than assuming an extension covers payment.

Are estimated tax payments only for self-employed people?

No. Estimated payments can matter when withholding is insufficient, including income from investments or other sources. The amount, timing and applicable safe harbor all matter. A refund at filing does not necessarily eliminate an earlier installment underpayment. Use the instructions for the relevant year.

What is the first step when an IRS letter arrives?

Identify the CP or LTR number, tax period, requested action and response deadline. Compare the notice with your records and retain a copy. If you disagree, follow the notice’s dispute instructions. Do not assume that an informal inquiry or a calculator result preserves an appeal deadline.
