IRS Notice CP2501: income discrepancy inquiry
A CP2501 is an early inquiry: income on a 1099 or W-2 doesn't match your return, and the IRS asks you to explain. It isn't an adjustment or a bill yet. A good reply now often settles it before a CP2000.

Why you got it
The IRS matches your return with forms from employers, banks, brokers and payment platforms. When the amounts differ, a softer CP2501 inquiry may come first, before a CP2000 with a recalculated tax.
What to do
- Compare each line in the letter with your 1099s, W-2s and statements.
- If the income is already on your return but on another line or form (for example Schedule C), explain where and attach copies.
- If the income really was left out, the reply usually needs an amended return, Form 1040-X. The letter says exactly what's expected.
- Send the reply by the date in the letter in a way that proves mailing, and keep a copy.
Don't ignore this inquiry. Without a reply the IRS recalculates your tax from its own data and sends a CP2000, often for more than you owe, because your expenses aren't in it.
