Where do chamber of commerce dues go?

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

Chamber of commerce dues belongs on Line 27a, other expenses.

Why line 27a

A chamber of commerce, a business league, a board of trade and a civic organisation of the same kind are all on the deductible side of the dues rule, so the membership is itemised in Part V and totals to line 27a. A leads or referral group such as BNI sits in the same place. As with any trade body, the share of dues spent on lobbying is not deductible and the chamber must tell you what it is, which matters here because chambers often lobby more than a professional institute does.

The limit that applies

Lobbying and political amounts inside the dues are not deductible and the organisation must report that portion to members.

What to keep

Keep the renewal invoice with the disclosed lobbying percentage, and keep sponsorship invoices separate so the advertising amount is not folded into dues.
