Deposit vs. payment
Employers often list the same amount twice
→ Verify each entry is a distinct transaction
Semi‑weekly vs. monthly schedule
Different deposit frequencies change reporting requirements
→ Check your deposit schedule in the Form 941 instructions
Zero‑deposit quarter
Some think Schedule B is still required
→ Use Form 941 without Schedule B if no deposits were made
E‑file attachment
Not all software attaches Schedule B automatically
→ Ensure the PDF includes both forms before submitting
Tax code column
Mislabeling Social Security as Medicare
→ Cross‑check with payroll tax summary
