Your business received a CP2030 — the entity version of a CP2000.
The IRS believes income reported to your corporation or partnership doesn't match the return. The mechanics mirror a CP2000, but the stakes scale with the entity.
What a CP2030 actually means
A CP2030 is sent to businesses (corporations, partnerships, certain trusts) when third-party income reports don't reconcile with the filed entity return. Like a CP2000, it proposes additional tax rather than billing it.
Business notices often stem from 1099-K marketplace reporting, merchant-processor figures, or interest and dividend income posted to the entity. Reconciling gross settlement amounts against booked revenue is usually where the discrepancy resolves.
Why you might have received one
- 1099-K marketplace gross exceeds booked revenue (refunds, fees not netted)
- Merchant-processor totals reported on a gross basis
- Income posted to the entity that belongs on an owner's return
- A late-arriving 1099 not reflected at filing
An unresolved CP2030 escalates the same way a CP2000 does, and the proposed assessment can affect estimated payments, owner K-1s, and downstream personal returns. A clean reconciliation protects the whole chain.
Common mistakes we see
- Treating 1099-K gross as taxable revenue without netting fees and refunds
- Failing to tie marketplace settlement reports to the books
- Ignoring the flow-through impact on owners' returns
- Letting the 30-day window lapse into a deficiency notice
