Form ST-5 New Jersey: Sales Tax Exemption for Microschools and Homeschool Co-ops

If your microschool or learning pod is organized as a 501(c)(3) nonprofit, New Jersey offers a meaningful operational savings: exemption from the state's 6.625% sales tax on eligible purchases. The mechanism is Form ST-5, the NJ Exempt Organization Certificate. Understanding when it applies — and when it does not — saves money and keeps your organization out of trouble with the Division of Taxation.

What Form ST-5 Does

Form ST-5 is not a filing you submit to the state. It is a certificate you present to vendors at the time of purchase to document that your organization qualifies for sales tax exemption. The vendor retains it as proof that the sale was exempt. You keep a copy on file.

The exemption covers purchases made by the exempt organization for use by the exempt organization in its exempt activities. That distinction matters for microschools: if you are buying curricula, books, art supplies, science equipment, or classroom furniture for use in your educational program, those purchases qualify. If you are buying materials that will be resold to families (even at cost), the exemption does not apply to those items.

New Jersey's 6.625% tax rate means a $10,000 annual supply budget saves your organization $662 per year. For organizations purchasing curriculum packages, technology, or equipment, the number grows fast.

Who Qualifies for Form ST-5

To receive a Form ST-5, an organization must:

1. Hold federal 501(c)(3) tax-exempt status. The IRS determination letter is the foundational requirement. A pending 501(c)(3) application does not qualify.
2. Apply to the NJ Division of Taxation for the exempt organization certificate. Approval is not automatic upon receiving 501(c)(3) status — you must separately apply in NJ.
3. Be organized and operated exclusively for exempt purposes — educational, religious, charitable, scientific, or literary purposes qualifying under IRC 501(c)(3).

Microschools organized as 501(c)(3) educational nonprofits clearly fall within the qualifying category. The NJ Division of Taxation's position is that organizations providing educational instruction qualify for the exemption.

LLCs and informal parent collectives do not qualify. If your pod operates as a for-profit LLC or as an unincorporated group, Form ST-5 is not available to you.

How to Apply

The application is Form REG-1E, the "Application for Exempt Organization Certificate." You file it with the NJ Division of Taxation.

What you will need:

• Your organization's EIN (federal Employer Identification Number)
• A copy of your IRS 501(c)(3) determination letter
• A description of your organization's activities and how they qualify for exemption
• The names and addresses of the principal officers
• Your organization's formation documents (certificate of incorporation and bylaws)

The Division of Taxation processes REG-1E applications and, if approved, issues the Form ST-5 certificate with your organization's exemption number. Processing typically takes four to eight weeks.

Once approved, your Form ST-5 is valid indefinitely — there is no annual renewal. However, if your organization's exempt status changes or is revoked, you must notify the Division of Taxation.

How to Use the Certificate at Point of Purchase

When purchasing qualifying items, present a completed Form ST-5 to the vendor before the transaction is finalized. The form requires:

• Your organization's legal name and address
• Your NJ exemption number
• A description of the purchase
• A statement that the purchase is for use in the organization's exempt activities
• Authorized officer signature

Vendors are permitted to accept the certificate in good faith. If a vendor refuses to honor it — which happens with some online retailers — you can pay the tax and file for a refund using Form A-3730 (Claim for Refund) within four years of the purchase.

Keep a copy of every ST-5 you issue, along with the corresponding receipt. If the Division of Taxation audits your purchases, you need documentation that each exempt purchase was actually for organizational use.

What the Exemption Does Not Cover

Several common purchases are not exempt even with Form ST-5:

• Meals and prepared food — NJ taxes prepared food regardless of buyer status
• Utilities — electricity, gas, and water billed to a nonprofit are not automatically exempt; a separate utility exemption application exists but has stricter requirements
• Purchases for resale — if you buy books to resell to families, you need a resale certificate, not ST-5
• Personal purchases — the exemption applies to organizational purchases only; individual founders using the certificate for personal purchases is fraud

The Tax Picture for LLC-Based Microschools

If your microschool operates as an LLC rather than a nonprofit, Form ST-5 is not available, but you are not without options.

NJ does not currently offer a homeschool tax credit or a specific microschool tax deduction. Several states have enacted education savings account programs or tuition tax credits, but New Jersey has not passed such legislation as of early 2026, despite the NJ Homeschool Bill proposals that have circulated in the legislature.

What LLC microschools can deduct as ordinary business expenses depends on whether the operation is a legitimate business generating revenue. If you charge tuition and operate as a business, standard business expense deductions apply — space, supplies, utilities, software. The critical issue is that the IRS distinguishes between a genuine for-profit business and a hobby; a microschool consistently losing money without a profit motive can lose its deduction eligibility.

Consulting a CPA familiar with NJ business taxes is worth the investment in your first year.

If you are organizing your microschool as a nonprofit and want a complete checklist for the formation process — IRS 501(c)(3) timeline, Form REG-1E, bylaws requirements, and the Form ST-5 application — the New Jersey Micro-School & Pod Kit has the full step-by-step documentation in one place.
