Kauai short-term rental rules & tax calculator

Kauai County, Hawaii · Verified against official sources Oct 24, 2026

📋 The Basics

Can I rent my place short-term here?: Only in some areas
Do I need a permit?: Only in Visitor Destination Areas, or with an old Nonconforming Use Certificate. No new ones outside VDAs.
What taxes do I pay?: Total about 18.5%. Check your Airbnb payout report to see which ones Airbnb collects; you pay the rest yourself.

Your 3 steps to be legal

Get Hawaii GET and TAT licenses.
Register with the County (or renew your certificate yearly).

⚠️ Biggest risk: Buying outside a VDA expecting to start a new vacation rental.
