Where do professional dues go on Schedule C?

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

Professional and union dues belongs on Line 27a, other expenses.

Why line 27a

Dues to an organisation whose purpose is your trade or profession are deductible, and there is no dues line in Part II, so they are itemised in Part V and carried to line 27a. This covers trade associations, professional institutes and the union or guild a self-employed tradesperson or performer pays into. One piece of arithmetic usually applies: the share of your dues the organisation spends on lobbying is not deductible, and the organisation has to tell you what that share is, so deduct the net figure rather than the amount on the invoice.

The limit that applies

Amounts a trade association spends on lobbying and political activity are not deductible, and the association is required to notify members of that portion. Deduct dues net of it.

What to keep

Keep the dues invoice, which is also where the nondeductible lobbying percentage is disclosed. Note on it the figure you actually deducted so next year's return is consistent.
