Preparing 941s for clients?

Every client’s Form 941 from one quarterly export

Payroll and bookkeeping firms already have each client’s quarter in a spreadsheet. Open the ready Form 941 template and upload that export, and MailMergic fills the header, the payroll lines, the 941-V voucher and your paid preparer section for every client, one PDF each, named after the client.

  1. 1Open the ready Form 941 template. Its boxes are already connected to columns like EIN, Quarter and Line 2 Wages, with the cents in a column of their own because the form has a box for them.
  2. 2Upload your client export, one row per client. MailMergic suggests which column goes in which box, and you confirm once.
  3. 3Generate one PDF per client, ready to review and sign. Every line comes from a column of your export, so check them like any return.

Form 941 questions

When is Form 941 due?

By the last day of the month after the quarter: April 30, July 31, October 31 and January 31. If you deposited all taxes for the quarter on time and in full, you have 10 more days.

Is the math on this page right?

It follows the form: column 2 of line 5 is column 1 times 0.124, 0.029 or 0.009, rounded to the cent, and lines 5e, 6, 10, 12, 14, 15a and the Part 2 total are the sums and differences the form describes. The results come from what you type, so check them against your payroll records.

What do I put on line 7?

The small difference left by rounding when you work out the tax per paycheck instead of for the whole quarter. Use a minus sign for a reduction, for example -0.03.

Do I need the 941-V voucher?

Only if you pay a balance due with the return by check or money order. This page fills the voucher on page 3 with the line 14 amount, your EIN, name, address and quarter.

Can I file this PDF with the IRS?

Yes, print it, sign it and mail it to the address in the instructions for your state, or e-file through a provider instead. Both pages are required.

Is my data safe on this page?

The PDF is filled and the math is done inside your browser. Nothing you type, including your EIN and bank details for a refund, is sent to MailMergic or anyone else, and nothing is stored.

Do I need a MailMergic account?

No. Filling one Form 941 is free and needs no account. MailMergic is for firms that need many filled forms, such as a 941 for every payroll client each quarter.
