Is a capital improvement exempt from sales tax in New Jersey?
Yes, but only with the paperwork. In New Jersey a capital improvement to real property is exempt to the customer, and the exemption is claimed by the customer giving the contractor Form ST-8. ⚠ The certificate IS the exemption. Without a signed Form ST-8 on file the job is taxable, however obviously it was a capital improvement — that is the single most common way a contractor loses a sales tax audit. A capital improvement is a permanent addition that becomes part of the property; a repair restores something to working order and is treated differently.

Notes
Repair and maintenance labor is taxable; capital improvement labor is exempt when the property owner gives the contractor Form ST-8, Certificate of Exempt Capital Improvement. The contractor pays tax on materials either way. Landscaping, floor covering and alarm installation have their own carve-outs.

How Seayora uses this rule
Seayora resolves this rule on every invoice a contractor raises — per line, from the job site’s own address — and prints the rate, the jurisdiction and this citation on the document itself, so the estimate a customer accepts is the invoice they are billed. Where the rule is more nuanced than a single answer, Seayora refuses to guess a total rather than quoting a confident wrong one.
