Hawaii sales tax rules for Plumbing contractors

Combined rate: 4% GET (Honolulu adds 0.5%).

Construction labor tax: Hawaii GET applies to virtually all business activity including contractor labor. Prime: 4% on gross; sub: 0.5% on gross.

Hawaii-specific rule: Hawaii GET applies to gross receipts including labor. Hawaii requires court order before recording lien - unusual among states.

For the latest filing requirements, check the Hawaii Department of Taxation. The KaamCam invoice template uses 4% as the default rate; adjust for your local jurisdiction.

Hawaii mechanics lien deadlines

General deadline: 45 days from completion.

Preliminary notice: Not required, but lien application requires court hearing.

The invoice template includes a lien deadline reminder so you don't lose collection rights. Always verify with a Hawaii attorney before filing.
