AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Find the notice number and the reply date printed on the letter, then respond by that date. A CP2000, the most common, is a proposal, not a bill: it says income reported to the IRS does not match your return, and you agree or disagree on the response form, with documents, by upload, fax or mail. Ignoring it lets the IRS send a bill; for foreign forms such as Form 8938, penalties can grow after an IRS notice.
First, identify the letter
Every IRS notice carries a notice or letter number printed on it, such as CP2000. That number tells you what the IRS thinks has happened. The reply-by date is printed on the notice itself; the IRS CP2000 page (reviewed July 2026) gives no fixed number of days, only "Reply to the notice by the date listed". Note the date in your calendar the day the letter arrives.
The CP2000: income that does not match
A CP2000 means information from third parties, such as employers, banks or brokers, does not match your return. It proposes changes to your tax and "isn't a bill", but a response may be required. For Nigerians in the US it often follows a US broker or bank reporting income you left out, or a foreign item that surfaced another way.
How to reply
- Read the proposed changes line by line against your records.
- Complete and sign the response form if one is enclosed, stating whether you agree or disagree.
- Attach evidence: statements, receipts, Nigerian withholding tax receipts, exchange-rate sources.
- Send it by the IRS document upload tool, by fax to the number for your notice's office shown on the notice, or by mail to the address in the top-left corner of page one.
- If you agree and have nothing else to report, you generally do not amend. If you agree and have other income, credits or expenses to add, such as a foreign tax credit for Nigerian tax, complete Form 1040-X, write "CP2000" at the top and send it with your reply.
Interest accrues until any balance is paid, and penalties may apply. If you do not reply, or the issue cannot be resolved, the IRS may send another notice and a bill.
Penalties tied to foreign reporting
Some foreign forms have their own penalty clocks, which a notice can start:
| Form | What it reports | Penalty described by the IRS |
|---|---|---|
| Form 8938 | Specified foreign financial assets above the thresholds | Up to US$10,000, plus US$10,000 for each 30 days of non-filing after an IRS notice, up to US$60,000 more |
| Form 3520 | Foreign gifts and bequests over US$100,000 | 5% of the gift for each month late, up to 25%, unless reasonable cause |
| FBAR (FinCEN 114) | Foreign accounts over US$10,000 in total | Civil penalties, inflation-adjusted; see our FBAR penalties guide |
For Form 8938, the clock after an IRS notice is the reason to act fast: the IRS comparison page (September 2026) says the additional penalty runs for each 30 days of non-filing after notification. For catching up on accounts, see FBAR penalties and catching up.
If the letter reveals years of missed reporting
A notice about one year often exposes a pattern, for example Nigerian accounts never reported on FBARs. The IRS streamlined domestic offshore procedures are for people who were non-wilful, fail the non-residency test and filed returns for the last three years: you file amended returns for three years and FBARs for six, and pay a 5% miscellaneous offshore penalty on the highest year-end total of the assets (IRS page reviewed July 2026). Whether you can still use them once the IRS has contacted you is a question for a tax professional before you reply. See streamlined filing for unreported Nigerian income and amending a return to add Nigerian income.
A worked example
Example only. Tolu receives a CP2000 in August 2026 for her 2024 return: a US brokerage reported US$2,400 of dividends she left out. While checking, she finds she also left out US$1,000 of Nigerian rent on which a corporate tenant withheld 10% (US$100 at her conversion rate). She signs the response form agreeing to the dividends, adds the rent and a US$100 foreign tax credit on a Form 1040-X marked "CP2000", and uploads both before the reply date. Her foreign accounts were below US$10,000 all year, so no FBAR issue arises; if they had been above it, she would have raised that with a preparer before replying.
Where Pryme fits
A reply is only as strong as its documents. Statements from a Pryme account can be produced as verifiable documents through VerifyDoc.ai, so the IRS or your representative can confirm they are unaltered (receipts and statements).
Questions people ask
Is a CP2000 a bill?
No. The IRS says it proposes changes because third-party information does not match your return. You agree or disagree by the date on the notice.
How long do I have to answer an IRS CP2000?
Until the reply date printed on the notice. The IRS page gives no fixed number of days, so use the date on your letter.
Do I need to file an amended return with my CP2000 reply?
Generally not if you agree and have nothing else to report. If you have other items, file Form 1040-X marked "CP2000" with your reply.
What happens if I ignore an IRS notice about Form 8938?
After an IRS notice, an extra US$10,000 penalty can apply for each 30 days of non-filing, up to US$60,000, on top of the initial US$10,000.
