Letter 4838: Payroll Service Provider Client: initial contact when your provider failed to deposit or file

What Letter 4838 is

Letter 4838, "Payroll Service Provider Client," may be the revenue officer's initial contact letter to an employer or payer whose third-party provider did not make the deposits or file the returns; it describes offer-in-compromise relief (IRM 5.1.24.5.1(2), Mar. 24, 2025). It arrives because the liability is yours: "The employer is liable for all taxes, penalties and interest due" (IRM 5.1.24.5(2), May 20, 2026). If it is established that you were the victim of provider failure or fraud, "all penalties on periods associated with the failure or fraud will be considered for abatement," but "Under no circumstances may interest be removed for reasonable cause" (IRM 5.1.24.5(2); 5.1.24.5.5(2)).

The deadline

No fixed response period is stated in the manual; respond by the date on the letter. Officers face trust fund recovery penalty exposure, and ignoring prior IRS notices is a listed willfulness factor (IRM 5.1.24.5.8).

What to do

Pull your own EFTPS history (an Inquiry PIN has been issued automatically to batch-provider clients since Jan. 24, 2014) and a transcript, and reconcile them to the returns and deposit reports the provider gave you (IRM 5.1.24.5.2(5), 5.1.24.5.3). Document that you had the funds and the provider "timely received or debited the funds," when you learned of the failure, and what you did next; those are the abatement factors (IRM 5.1.24.5.5(2)-(3)). Ask for penalty relief under the Reasonable Cause Assistant's "Reporting Agent" category (IRM 5.1.24.5.5.1). For the tax itself, the manual's route is Form 656 marked in red "Payroll Service Provider Offer"; financial statements are not required when the offer equals the full tax exclusive of penalty and interest (IRM 5.1.24.5.7). Confirm your address of record was not changed to the provider's (IRM 5.1.24.5.4).

Why the liability is yours

Hiring a payroll service provider or a reporting agent does not move the tax obligation. The employer or payer remains liable for the deposits, the returns and any penalties and interest, whatever the contract with the provider says, and the IRS collects from the client when the provider fails. Letter 4838 is the revenue officer's opening letter to a client in that position: the provider did not deposit the withholding it collected, or did not file the returns, or both, and the account now shows unpaid tax, failure-to-deposit and failure-to-file penalties, and interest. It describes the relief the IRS offers to provider-failure victims, which is real but limited. Penalties on the affected periods are considered for abatement if you can show the provider had the money and you acted when you learned of the problem. The tax itself is still owed; interest is never removed for reasonable cause; and the officers of the business face personal exposure for the trust fund portion if the matter is ignored.

The IRS's standing advice to clients of payroll providers is to use EFTPS to confirm deposits independently. Clients of batch providers receive an EFTPS Inquiry PIN automatically for that purpose, and a client who never looked is in a weaker position on reasonable cause than one who checked and was deceived.

Assembling the response

Start with the facts the IRS can verify: your own EFTPS payment history and an account transcript, reconciled against the deposit reports and return copies the provider gave you. The gap between the two is the case. Document that you funded the provider (bank statements showing the debits or transfers), that the provider received the money before the deposit due dates, when you first learned of the failure, and what you did then (changed providers, made the deposits yourself, reported the provider). Those are the factors the IRS weighs for penalty relief, and the request should go in writing under the reporting-agent reasonable-cause category with the evidence attached. For the tax, the manual's route for a client who can pay the tax but not the penalties and interest is an offer in compromise on Form 656 marked as a payroll service provider offer; the IRS does not require financial statements when the offer equals the full tax. Also check that your address of record was not changed to the provider's, which is how some clients missed every notice that preceded this letter. The reporting agents guide covers the Form 8655 relationship, and the relief order guide covers which relief to ask for first.
