Why did I get it?

The IRS issues Notice CP12 when its records show a specific condition on your account. The notice itself states the amount, the tax year, and the date the IRS is working from. If any of that looks wrong, it often is worth challenging, and confirming the details is the first thing we do.

What happens if I ignore it?

If you do nothing, the balance continues to grow with penalties and interest, and the IRS escalates toward liens, levies, and wage garnishment. Every notice has a response window, and the options are widest before it closes.

What to do after Notice CP12

Three steps, whether you handle it yourself or have us step in.

Do not miss the deadline

Notice CP12 carries a response date: Review within 60 days. Mark it, because the IRS's next step is usually more serious.

02

Confirm the details

The IRS is sometimes wrong. We pull your transcripts and verify whether the amount and the basis for the notice are correct before responding.

03

Respond with a plan

Check the correction. If it is wrong, you have a limited window to contest it. We respond on your behalf and take the deadline pressure off you.
