What is a Write-Off — and How Do You Actually Measure It?

"Write it off" is something everyone says. But what does it actually mean mathematically — and what records do you need to make it stick in an audit?

Notices

CP2000: The IRS Says Your Income Doesn't Match. Now What?

A CP2000 isn't a bill and it isn't an audit — but ignoring it turns into both. Here's exactly what it means and the steps to respond correctly.

Audits

3 Types of IRS Audit: Which One Did You Get and What Does It Mean?

A correspondence audit is very different from an in-person one. Knowing which type you've been selected for completely changes what you need to do.

Home Office Deduction: The Simplified Method vs. the Real One

The simplified method is easy. The regular method puts more money back in your pocket. Here's how to calculate both and decide which is right for you.

Notice Decoder

Got one of these? Here's what it means

The most common IRS notices — decoded in plain English so you know exactly what you're dealing with.

CP2000

Income Discrepancy Notice

The IRS received income information that doesn’t match your return — usually from a W-2, 1099, or bank. It proposes changes to your tax. Not an audit, but requires a response within 60 days.

Respond within 60 days

CP501

Balance Due Reminder

You have an outstanding balance on your tax account. This is the IRS’s first reminder. It can escalate to a CP503 and then CP504 (intent to levy) if not addressed.

Pay or respond promptly

CP504

Intent to Levy Notice

The IRS intends to seize your state tax refund to satisfy your balance. This is a serious escalation — ignoring it can lead to bank levies or wage garnishment.

Act immediately

Letter 531

Notice of Deficiency

The IRS is proposing an increase to your taxes after an audit. You have 90 days to file a petition in Tax Court or pay the amount. Missing this deadline forfeits your right to contest.

90-day deadline

CP12

Changed Your Refund

The IRS found a math error on your return and corrected it — resulting in a different refund than you expected. Usually good news (refund was increased) or a correction you need to review.

Review and confirm

Letter 3219

Statutory Notice of Deficiency

Also called a “90-day letter.” This is the formal legal notice giving you 90 days to challenge the IRS’s proposed assessment in Tax Court before it becomes final.
