A CP134B flags a mismatch between what you reported on Form 941 and what the IRS shows as received. It's fixable — but payroll tax issues compound fast and carry personal liability risk.
A CP134B is sent to businesses when there's a discrepancy between the federal payroll tax deposits reported on your Form 941 (quarterly) — or 943/944 for annual filers — and what the IRS actually has recorded as deposited for that period. In short: the numbers on your return and the numbers in the IRS's deposit system don't line up, and the IRS wants that reconciled.
This is a mismatch notice, not automatically proof that a deposit was missed. But it needs to be taken seriously regardless of the cause, because payroll tax debt behaves differently than income tax debt.
Why payroll tax discrepancies are higher-stakes than they look: unpaid payroll tax can trigger the Trust Fund Recovery Penalty, which makes the withheld portion personally collectible from owners, officers, or anyone the IRS determines was responsible for making the deposits — regardless of the business's corporate structure. A CP134B is worth resolving quickly, not setting aside.
We reconcile your actual deposit records against what the IRS has on file, identify exactly where the mismatch originated, and prepare the documented response. If it turns out a deposit is genuinely missing, we help you resolve it fast — before penalties compound further and before Trust Fund Recovery Penalty exposure becomes a personal issue for the people responsible for payroll at your business.

It's a mismatch notice, not necessarily proof that a payment was missed.
Not necessarily. It often means a deposit was misapplied to the wrong quarter or wrong EIN, made through the wrong deposit method, or simply not yet processed and matched by the IRS at the time the notice was generated. It can also reflect a genuine underpayment.
Quickly. Payroll tax discrepancies compound every quarter they go unresolved, and the Trust Fund Recovery Penalty makes payroll tax debt personally collectible from responsible individuals in a business, not just the business entity. This is one of the more urgent notice types.
Deposit confirmations (EFTPS records or bank statements showing the transfers), copies of the Form 941 as filed, and your internal payroll register for the quarter in question. Together these show what was actually deposited versus what the IRS has recorded.
