IRS CP2501:here's whatit means.
Income doesn't match your return. The IRS found income reported by an employer, bank, or broker that may be missing from your return. It's an early inquiry, not a bill.

Common questions.
Is IRS CP2501 real or a scam?
Real IRS notices arrive by U.S. mail, not by text, social media, or a surprise phone call demanding payment. To verify, compare it with your IRS online account or call the number listed on IRS.gov, not a number from a suspicious message. We can check it for you.
Can MM.TAX respond to IRS CP2501 for me?
Yes. Our practice is led by an IRS Enrolled Agent. We file a power of attorney (Form 2848), pull your transcripts, and respond to the IRS for you, online anywhere in California.
What if I can't pay what the IRS says I owe?
You have options: an installment agreement, an Offer in Compromise if you qualify, penalty abatement, or currently-not-collectible status during hardship. The right choice depends on your income, assets, and the amount owed.
