Is construction labour subject to US sales tax?

It varies widely by state. Many states tax materials but exempt installation or repair labour; others tax the full contract; rules also differ for new construction versus repair. Enter your combined state-plus-local rate and use the labour toggle to model how your state treats labour.

What rate should I enter?

Enter your combined rate — the state base rate plus any county, city or district sales tax that applies at the project location. Because local rates stack, the effective rate at a job site is often higher than the headline state rate.

Is this sales-tax figure final?

No. It is an indicative estimate for budgeting and cross-checking. Taxability of materials versus labour, contractor-versus-retailer treatment and local rates all vary by jurisdiction. Always verify with a qualified tax professional.
