1. Don’t ignore it
Most notices have a response date. Missing it can mean extra penalties and interest, and you can lose the chance to dispute a change. Open the letter as soon as it arrives.
2. Find the notice number and the deadline
Look in the top or bottom right corner for a code such as CP2000 or LTR 5071C. Note the tax year, the amount (if any) and the date you must respond by.
3. Check that it’s genuine
The IRS usually starts contact by mail. It will not demand immediate payment by gift card, wire transfer or cryptocurrency, or threaten to have you arrested. If something feels wrong, don’t call numbers or click links in the letter. Text us a photo before you reply or pay.
4. Have it checked
Many notices come from a mismatch, such as a 1099 the IRS received that isn’t on your return, or a payment that wasn’t matched to your account. Notices are sometimes wrong, and you have the right to disagree. We compare the notice with your return and records for you.
5. Respond before the deadline
Whether you agree, disagree or need a payment plan, the response needs to reach the IRS on time and with the right documents. We prepare and send it for you.
Common notices, in plain English
- CP2000: income or payments reported to the IRS don’t match your return. It proposes changes; you can agree or disagree.
- CP14: you have a balance due.
- CP501 and CP503: reminders that a balance is still unpaid.
- Letter 5071C: the IRS needs to verify your identity before it processes a return in your name.
Virginia Tax letters
Virginia Tax sends its own bills and letters, for example when it adjusts a return or needs more information. The same rules apply: don’t ignore it, note the deadline, and send it to us so we can check it and respond on time.
