Where do Thumbtack lead fees go on Schedule C?

Updated October 10, 2026 路 Schedule C, Line 10
Short answer Schedule C, Line 10 Commissions and fees

Pay-per-lead fees from Thumbtack, Angi or Yelp belongs on Line 10, commissions and fees.

Why line 10

These land on the advertising line constantly, because the platform sells them as marketing. But a charge that happens only when a named customer contact or booking arrives is a fee for producing that piece of business, and that is what line 10 is for. Line 8 buys exposure at a fixed price whether anyone responds or not. Read the invoice: if the unit is a lead, a booking or a percentage of the job, it is line 10.
