The short answer

An IRS audit is a review of your return and records to make sure they are right. The IRS starts an audit by mail, never by phone. Most audits look at returns filed in the last 2 years.

What to know first

It starts by mail

The IRS notifies you of an audit by mail. It won't start an audit by phone.

It may not mean a problem

Some returns are picked by a formula or because they are tied to someone else's audit.

How far back

Usually returns from the last 3 years. If there is a big error, more years may be added, but usually not more than 6.

Ask for more time

For mail audits, the IRS can usually grant a one time 30 day extension.

Answer by the date

If you don't respond, the IRS finishes the audit without you and sends its proposed changes.

You can have help

You have a right to representation. Enrolled agents, CPAs and attorneys can represent you on any matter.

Common questions

How long should I keep records?

The law says keep the records you used to prepare a return for at least 3 years from the date you filed it.

Is a CP2000 an audit?

It is a notice that income reported to the IRS does not match your return. It is not a bill, but you may need to reply by the date listed.

Do I have to agree to extend the time limit?

No. But if you don't agree, the auditor will decide based on what you already gave.
