# Running a home improvement business in New Jersey

The State is strict about four things: registration, insurance, written contracts and sales tax. Get them right and you're ahead of most of your competition. Here's each one, from the source.

## Registration and insurance

- Home improvement contractors register with the Division of Consumer Affairs every year, including part-time and out-of-state contractors. Initial registration is $110; renewal is $90 by March 31, online. ([Consumer Affairs](https://njconsumeraffairs.gov/hic/Pages/FAQ.aspx))

- You need commercial general liability insurance of at least $500,000 per occurrence, plus workers' comp unless you're exempt.

- Your registration number goes on your ads, business cards, trucks, contracts and every business document.

## Contracts over $500

Must be in writing and signed by everyone, with your legal name, address and registration number, a description of the work and main materials, the total price, start and finish dates, and a copy of your insurance certificate. ([N.J.S.A. 56:8-151](https://law.justia.com/codes/new-jersey/2020/title-56/section-56-8-151/), [N.J.A.C. 13:45A-16.2](https://www.law.cornell.edu/regulations/new-jersey/N-J-A-C-13-45A-16-2)) The customer can cancel for any reason until midnight of the third business day, and the contract has to say so in bold type of at least 10 points.

## Sales tax: repairs vs. improvements

Repair and maintenance labor is taxable. A capital improvement is exempt when the owner gives you a signed Form ST-8. You pay sales tax on materials when you buy them either way, with narrow exceptions. ([NJ Treasury S&U-3](https://nj.gov/treasury/taxation/pdf/pubs/sales/su3.pdf))

## Subs and 1099s

Get a W-9 from every subcontractor before you pay them. For payments of $2,000 or more in 2026, send a 1099-NEC by January 31. ([IRS](https://www.irs.gov/pub/irs-pdf/i1099mec.pdf)) [New Jersey's ABC test](/bookkeeping/guides/nj-independent-contractor-rule-abc-test-2026) decides whether someone is really a sub.
