Schedule R (Form 943), Allocation Schedule for Aggregate Form 943 Filers, is an Internal Revenue Service (IRS) schedule that you attach to an aggregate Form 943 or Form 943-X. It splits certain totals from that return among the clients the filer serves, one client employer identification number (EIN) at a time. Agents approved under section 3504 and certified professional employer organizations (CPEOs) complete it each time they file an aggregate Form 943. On FillingPDF you can fill out the schedule online and download or print the completed PDF; the IRS publishes the form and its instructions at irs.gov.

What is Schedule R (Form 943)?
Schedule R (Form 943), Allocation Schedule for Aggregate Form 943 Filers, is the IRS schedule on which a filer of an aggregate Form 943 allocates certain amounts reported on Form 943 or Form 943-X to each client, identified by the client's employer identification number (EIN).
For this schedule, a "client" means one of the following:
- an "employer or payer" identified on Form 2678, Employer/Payer Appointment of Agent;
- a customer who enters into a contract that meets the requirements of section 7705(e)(2);
- a client with a service agreement described in Regulations section 31.3504-2(b)(2) with a certified professional employer organization (CPEO);
- a client with a service agreement described in Regulations section 31.3504-2(b)(2) with a non-certified professional employer organization (PEO);
- a third party paying qualified sick leave wages as an agent for the employer under Regulations section 32.1(e)(3).
The schedule has columns a through y. Each client row reports the client's EIN, the wage, tax, credit and deposit amounts allocated to it, and, for CPEOs, a code for the type of wages paid. Lines 6 through 9 subtotal and total the columns. The totals on line 9 must match the totals on the aggregate Form 943.
Columns e, f, k, l, n, and p through y are used only when Schedule R is attached to Form 943-X. If you have more than five clients, you complete as many Continuation Sheets as necessary. The schedule is not filed alone: you attach it, with any Continuation Sheets, to your aggregate Form 943. The IRS instructions for this schedule are dated Rev. December 2025.
Who needs to file Schedule R (Form 943)?
Two groups must complete Schedule R every time they file an aggregate Form 943:
- agents approved by the IRS under section 3504; and
- CPEOs.
An agent must have filed Form 2678 and had it approved by the IRS before filing Schedule R. An organization becomes a CPEO by applying through the IRS Online Registration System.
Other third-party payers that file aggregate Forms 943, such as non-certified PEOs, must complete and file Schedule R if they have clients claiming the qualified small business payroll tax credit for increasing research activities. These payers need to give client-by-client amounts only for those clients. Amounts for clients not claiming that credit go in the consolidated figures on page 1, line 8. Non-certified PEOs and third-party payers of sick pay as agents for the employer include on line 8 any client amounts not reported individually.
Schedule R must also be completed if any clients are claiming credits on Form 943-X.
You do not need this schedule if you do not file an aggregate Form 943.
When to file Schedule R (Form 943)
If you are an aggregate Form 943 filer, file Schedule R with your aggregate Form 943 every year. The schedule has no separate due date: it travels with the Form 943, or with the Form 943-X, to which you attach it.
Enter the calendar year of that Form 943 or 943-X on the schedule. Do not file an earlier revision of Schedule R with Form 943 for any year beginning after 2024. If you file Form 943-X to claim the COBRA premium assistance credit for clients, you must use the 2024 or 2025 revision of Schedule R.
For credits for qualified sick and family leave wages paid after 2023, the IRS instructions say to file Form 943-X after filing Form 943 for the year. Filing Form 943-X first may cause errors or delays in processing.
Documents you need
- The aggregate Form 943 (or Form 943-X) to which Schedule R is attached; the EIN, business name and totals on the schedule must match it.
- Continuation Sheets for Schedule R (Form 943), only if you have more than five clients; attach them with Schedule R.
- A separate Form 8974 for each client claiming the qualified small business payroll tax credit for increasing research activities (column j).

Enter subtotals and Form 943 amounts

How to submit Schedule R (Form 943)
Schedule R is submitted as an attachment to your aggregate Form 943 or Form 943-X, on paper or electronically, depending on the type of filer.
- Attach it to the return. Attach Schedule R, including any Continuation Sheets, to your aggregate Form 943. Use the filing channel for that return; the Schedule R instructions print no separate mailing address.
- Agents and non-certified PEOs. They may file Form 943 and Schedule R electronically or by paper submission.
- CPEOs. They must generally file Form 943 and Schedule R electronically. See Rev. Proc. 2023-18, 2023-13 I.R.B. 605, available at IRS.gov/irb/2023-13_IRB#REV-PROC-2023-18.
- Amended returns. The IRS offers filing an amended Form 943 and Schedule R through Modernized e-File (MeF). For more on electronic filing, go to IRS.gov/EmploymentEfile.
Attach a separate Form 8974 for each client claiming the qualified small business payroll tax credit for increasing research activities. FillingPDF lets you fill out and download the PDF; submission follows the IRS channels above.
Common mistakes to avoid
- Entering an EIN or business name that does not exactly match the attached Form 943 or 943-X.
- Leaving the calendar year blank; the field is no longer prepopulated, so enter the year of the Form 943 or 943-X you attach the schedule to.
- Typing commas in amounts over 999.99; the instructions say not to enter commas.
- Filling columns e, f, k, l, n, or p through y on a schedule attached to Form 943; those columns are used only with Form 943-X.
- Filing an earlier revision of Schedule R with Form 943 for a year beginning after 2024.
- Letting the line 9 totals differ from the totals on the aggregate Form 943; the mismatch is an error to correct before filing.
- Omitting a separate Form 8974 for each client claiming the research-activities payroll tax credit reported in column j.
- Entering anything in column b other than code A, B, C, or D, or completing it as a non-CPEO; the column is CPEO use only.
