Where does a payroll service go on Sch C?

Updated October 10, 2026 路 Schedule C, Line 27a
Short answer Schedule C, Line 27a Other expenses (itemised in Part V)

A payroll service belongs on Line 27a, other expenses.

Why line 27a

The fee a payroll provider charges to run the pay run, file the returns and produce the W-2s is an administrative service cost, usually described in Part V as payroll service fees and carried to line 27a. It is entirely separate from what the service pays out: the wages themselves are line 26 and the employer payroll taxes are line 23. If the provider also does your bookkeeping or your tax filing as a professional engagement, that part of their bill is line 17.

Stop looking up lines one at a time. ClaryBook totals your year into an IRS Schedule C worksheet in form order, Part I and Part II line by line, so a payroll service lands on Line 27a without you sorting it.

What a payroll service is confused with

Line 26, wages
The gross wages the service disburses are line 26, so only the provider's own fee reaches line 27a and the two must never be combined.
Line 23, taxes and licenses
The employer share of social security, Medicare and unemployment tax that the service remits is taxes on line 23, not part of the service fee.
Line 18, office expense
If payroll comes bundled inside the accounting software subscription you already deduct as office expense, keep it on line 18 rather than splitting one invoice across two lines.

What does not belong here

What to keep

Keep the provider's monthly invoices, which separate the service fee from the funded wages and taxes. The quarterly payroll returns support the line 26 and line 23 figures.
