A New Jersey sales tax exemption removes the 6.625% state sales tax from a purchase, either because of what you’re buying, who you are, or how the item will be used. Some exemptions apply automatically at the register. Others require you to hand the seller a completed exemption certificate before the sale. A few, like the reduced rate in Urban Enterprise Zones, aren’t full exemptions at all but partial rate cuts. Knowing which category your purchase falls into is the difference between paying the right amount and either overpaying at checkout or facing an assessment later.
Purchases That Are Exempt Automatically
For a large share of everyday spending, you don’t need to do anything. The retailer is responsible for identifying exempt products and skipping the tax at checkout. No form, no ID number, no paperwork.
- Clothing and footwear for everyday human use. Fur clothing, accessories like handbags and jewelry, sport and recreational equipment, and protective gear such as hard hats and safety goggles are not covered.1Justia. New Jersey Code 54:32B-8.4 – Clothing, Footwear, Exemption from Tax; Definitions
- Food and food ingredients for home consumption. Prepared food sold ready to eat at restaurants, delis, and food trucks is taxable.2New Jersey Department of the Treasury, Division of Taxation. New Jersey Division of Taxation TB-71 – Sales of Prepared Food by Food Service Providers
- Disposable paper products for household use, such as paper towels, toilet paper, and paper plates.
- Prescription drugs, over-the-counter medications, prosthetic devices, diabetic supplies, and medical oxygen sold for human use.3Justia. New Jersey Code 54:32B-8.1 – Exemption for Certain Medical Supplies, Equipment; Definitions
- Machinery, equipment, seeds, fertilizer, and other tangible property used directly in farming, when purchased by a farmer for use in a farming enterprise.4Legal Information Institute. N.J. Admin. Code 18:24-19.8 – Other Exemptions Specifically for Farmers
If the register rings up sales tax on one of these categories, that’s a mistake on the seller’s part, not something you claim after the fact.
Exemptions That Require a Certificate
When the exemption depends on who’s buying or how the item will be used, the buyer has to document it. New Jersey uses four main certificates, each for a different situation.
Form ST-3, Resale Certificate. A business buying inventory or components it intends to resell hands this to its supplier to purchase tax-free. A retail appliance store buying stock from a distributor, or a furniture maker buying lumber, would use ST-3. Out-of-state sellers without a New Jersey presence use Form ST-3NR.5New Jersey Division of Taxation. Form ST-3 – Sales Tax Resale Certificate6New Jersey Division of Taxation. Resale Certificate for Non-New Jersey Sellers
Form ST-4, Exempt Use Certificate. For purchases the law exempts based on how the property or service will be used, such as research and development or manufacturing production.7New Jersey Division of Taxation. New Jersey Division of Taxation Sales Tax Form ST-4 Exempt Use Certificate
Form ST-5, Exempt Organization Certificate. Issued by the Division of Taxation to approved nonprofits after review. You cannot create your own ST-5 or use a certificate issued by another state.8Division of Taxation. Sales Tax Information for Exempt Organizations
Form ST-8, Certificate of Exempt Capital Improvement. Completed by a property owner and given to a contractor performing a capital improvement, so the contractor doesn’t charge tax on installation labor.9Legal Information Institute. N.J. Admin. Code 18:24-5.7 – Contractor Purchases and Capital Improvements
Most certificates require a valid New Jersey Taxpayer Identification Number, which businesses receive when they register using Form NJ-REG.10State of New Jersey – Department of the Treasury – Division of Revenue and Enterprise Services. Division of Revenue and Enterprise Services Business Registration Certificate The completed certificate has to reach the seller before or at the time of purchase. If you forget, the seller is required to collect the full 6.625%, and you’ll have to chase a refund separately.11New Jersey Division of Taxation. Sales Tax Exemption Administration
For recurring purchases with the same vendor, a blanket certificate can stay on file. As long as no more than 12 months pass between transactions, the seller can rely on the single certificate without collecting a new one each time.11New Jersey Division of Taxation. Sales Tax Exemption Administration
Urban Enterprise Zones and Salem County
Shopping at a certified business inside an Urban Enterprise Zone gets you a reduced rate of 3.3125%, half the standard 6.625%.12NJ Division of Taxation. Urban Enterprise Zone The reduced rate applies to most taxable physical goods at participating retailers, but not to motor vehicles, energy, or telecommunications and utility services. More than 30 municipalities participate, including Newark, Jersey City, Camden, Trenton, Paterson, and Elizabeth.13Urban Enterprise Zone Authority. UEZ Locations
Certified UEZ businesses get a stronger break on their own purchases: most taxable goods and services can be bought with no sales tax at all, again except motor vehicles, energy, and telecom services. Qualified UEZ manufacturers also get an exemption on natural gas and electricity used in manufacturing.12NJ Division of Taxation. Urban Enterprise Zone
Salem County businesses authorized under the UEZ program collect at the same 3.3125% rate, using Form ST-475S.14NJ Division of Taxation. Urban Enterprise Zone/Salem County Businesses
Manufacturing Equipment
Businesses engaged in manufacturing, processing, assembling, or refining tangible goods can buy qualifying machinery and equipment tax-free. The equipment has to be used directly and primarily in production, not in an ancillary role like office administration or general facility maintenance.15Justia. New Jersey Code 54:32B-8.13 – Sales of Machinery, Apparatus or Equipment
The exemption also covers equipment used in generating or distributing gas, electricity, refrigeration, steam, or water for sale, and broadcast and telecommunications equipment used directly in producing or transmitting content. Replacement parts with a useful life over one year qualify. Consumable tools and supplies used incidentally do not.15Justia. New Jersey Code 54:32B-8.13 – Sales of Machinery, Apparatus or Equipment Document these purchases with an ST-4 Exempt Use Certificate.
Capital Improvements Versus Repairs
Installation labor for a capital improvement to real property is exempt from sales tax. Labor for a repair is taxable. A new roof is a capital improvement. Patching a leak in the existing roof is a repair. New energy-efficient windows are a capital improvement. Replacing a broken pane is a repair.
The property owner gives the contractor a completed ST-8, and the contractor keeps it on file. The contractor still owes sales tax on the materials they buy for the job, but they don’t charge tax to the customer on the installation services.9Legal Information Institute. N.J. Admin. Code 18:24-5.7 – Contractor Purchases and Capital Improvements
If the property owner buys the construction materials directly from a store instead of having the contractor supply them, the owner pays sales tax on those materials. The capital improvement exemption in that scenario applies only to the separately stated labor charge.9Legal Information Institute. N.J. Admin. Code 18:24-5.7 – Contractor Purchases and Capital Improvements
Three types of installation work are always taxable, even when they’d otherwise qualify as capital improvements: landscaping services, floor covering installation, and alarm or security system installation. Subcontractors follow the same rules as prime contractors.16Legal Information Institute. N.J. Admin. Code 18:24-5.12 – Subcontractor Purchases and Services
Nonprofit and Government Buyers
The State of New Jersey, its agencies, public authorities, and political subdivisions are exempt on purchases made with government funds, and so are the federal government and the United Nations.17Justia. New Jersey Code 54:32B-9 – Exempt Organizations Federal agencies operating in New Jersey generally need a purchase order or signed document on agency letterhead to validate the exemption at the register.18GSA SmartPay. New Jersey Tax Information
Nonprofits qualify through the ST-5 certificate, but the qualifying list is narrower than many organizations assume. The primary category is 501(c)(3) organizations organized exclusively for charitable, scientific, literary, or educational purposes, or the prevention of cruelty to children and animals.19New Jersey Division of Taxation. Application for ST-5 Exempt Organization Certificate for Nonprofit Exemption from Sales Tax A few other groups also qualify: volunteer fire companies, rescue and emergency squads, veterans’ organizations, and parent-teacher associations at elementary or secondary schools.20New Jersey Division of Taxation. Nonprofit Organizations and Government Entities
Organizations with 501(c)(4), 501(c)(5), 501(c)(6), or 501(c)(7) status generally do not qualify unless they fall into one of those specific categories, and federal tax-exempt status alone is not enough.20New Jersey Division of Taxation. Nonprofit Organizations and Government Entities The application is Form REG-1E, filed with the Division of Taxation.21Division of Taxation. Nonprofit Organizations
Once approved, the exemption covers goods, equipment, motor vehicles, services, meals, admissions, and hotel stays directly related to the organization’s exempt purpose. The organization pays with its own funds and gives vendors a copy of its ST-5. Energy purchases remain taxable.8Division of Taxation. Sales Tax Information for Exempt Organizations
A Boundary: Digital Products Are Usually Taxable
Downloaded movies, TV shows, music, podcasts, ringtones, and digital books are taxable at the full 6.625% rate as “specified digital products.” Streaming video-on-demand, broadcast programming services, digital photographs, and digital magazines fall outside that category, though some can still be taxable under separate provisions for information services depending on how they’re delivered. Access without a download may be exempt because nothing was “transferred electronically” to you, but the line between access and delivery is not always clean, and Division guidance in this area continues to evolve.22New Jersey Division of Taxation. ANJ-27 Specified Digital Products and New Jersey Sales Tax
Buying From Out of State Doesn’t Sidestep the Tax
New Jersey imposes a use tax at the same 6.625% rate on taxable items you buy from out-of-state sellers, online retailers, or catalogs when the seller didn’t collect New Jersey sales tax. If you paid a lower sales tax rate to another state, you owe New Jersey the difference.23Department of the Treasury – Division of Taxation. Use Tax FAQ
Individuals report and pay use tax on Form NJ-1040, or on Form ST-18 if they don’t file an income tax return. The Division publishes an Estimated Use Tax Chart for people without detailed receipts.23Department of the Treasury – Division of Taxation. Use Tax FAQ The same exemptions described above apply equally to use tax: if the item would be exempt in a New Jersey store, it’s exempt when bought out of state too.
Getting Back Sales Tax You Shouldn’t Have Paid
If you paid tax on a purchase that should have been exempt, start with the seller. If the seller has already remitted the tax to the state, file a Claim for Refund on Form A-3730 with the Division of Taxation, along with receipts, invoices, and whatever exemption certificate should have applied.24Legal Information Institute. New Jersey Administrative Code 18:2-5.8 – Refund Claim Procedures25State of New Jersey Division of Taxation. Claim for Refund (Business Taxes ONLY) – A-3730
The statute of limitations is four years for returns with an original due date on or after July 1, 1993.26New Jersey Division of Taxation. New Jersey Taxpayers’ Bill of Rights File promptly if you spot a recurring overpayment, because waiting is the most common reason refund claims get denied.
Penalties for Misusing an Exemption
Issuing a resale or exempt-use certificate for personal purchases or non-exempt business use exposes both the buyer and the business to back taxes, penalties, and interest on every transaction where the certificate was improperly used. Sellers must accept properly completed certificates in good faith and keep them on file for at least four years, which is also the window the Division has to reconstruct these transactions during an audit. Businesses that accept certificates they know or should know are fraudulent lose the good-faith protection that would otherwise shield them from liability.11New Jersey Division of Taxation. Sales Tax Exemption Administration
Interest on any unpaid tax runs at three percentage points above the prime rate, compounded annually, and a civil fraud finding can add a penalty equal to 50% of the assessment.27Legal Information Institute. N.J. Admin. Code 18:2-2.4 – Failure to Pay on Time The economics of stretching an exemption to cover something it wasn’t meant for almost never work out.
