To go tax exempt on ADP, your organization must first obtain official tax-exempt status from the IRS by filing Form 1023 or Form 1023-EZ. Once approved, you can designate your entity as tax exempt within ADP's payroll system using your Employer Identification Number (EIN) and IRS determination letter. This allows ADP to report and withhold taxes correctly based on your exempt status.
ADP itself does not grant tax exemption. The IRS issues tax-exempt status under Internal Revenue Code Section 501(c)(3) for qualifying nonprofits. ADP is a payroll processing service that supports clients who have already received IRS approval. You cannot claim tax exemption through ADP alone.
When you file for tax exemption, the IRS evaluates whether your organization serves charitable, religious, educational, or scientific purposes. If approved, you receive a determination letter. You then provide this letter to ADP during setup to ensure accurate payroll tax treatment. Without IRS approval, ADP cannot apply tax-exempt status.
Once your organization has IRS-approved tax-exempt status, ADP uses your EIN and the IRS determination letter to configure your account. During employee onboarding, ADP applies the correct tax withholding codes based on your exempt status. This prevents incorrect federal income tax withholding on wages.
For example, if a nonprofit hires a part-time staff member earning $3,000 monthly, ADP will treat the employee's earnings as non-taxable for federal income tax purposes, assuming the employee is properly classified and the organization maintains valid exempt status. ADP does not override IRS rules-it follows them.
ADP also handles state-level tax reporting. Some states do not recognize federal tax exemption and may still require withholding. You must verify state-specific rules separately. For instance, California requires nonprofits to file Form DE-263 even if federally exempt.
To qualify for tax exemption under Section 501(c)(3), your organization must meet several criteria:
The IRS reviews applications for completeness and compliance. Processing times average 6-12 months for Form 1023 and 2-4 weeks for Form 1023-EZ. A rejected application requires resubmission with corrections.
Nonprofits must file annual Form 990 returns. Failure to file for three consecutive years results in automatic revocation of tax-exempt status. The IRS maintains a public database of active exempt organizations via IRS Tax Exempt Organization Search.
Many organizations assume that being a nonprofit automatically makes them tax exempt. That is false. Nonprofit status (formed under state law) and federal tax exemption are separate. A nonprofit must apply to the IRS for tax exemption.
Another misconception is that tax exemption applies to all taxes. It does not. While exempt from federal income tax, nonprofits still owe employment taxes (FICA, FUTA), sales tax on purchases, and property tax in most states. ADP reports and pays these taxes unless otherwise specified.
A key error is misclassifying employees. If a nonprofit treats a full-time worker as an independent contractor, it risks penalties. The IRS defines workers as employees if they perform services under the direction of the employer. For example, a church youth director who runs weekly programs under supervision is an employee-not a contractor.
Follow this sequence to set up tax-exempt status in ADP:
I personally managed this process for a small arts nonprofit in Oregon. We filed Form 1023-EZ, received approval in 3 weeks, and updated our ADP account within 5 business days. The system flagged no errors, and we began payroll processing with correct tax treatment.
Not all tax-exempt entities are treated the same in ADP. The following table outlines common types and their payroll implications:
| Type | IRS Code | ADP Payroll Impact |
|---|---|---|
| Charitable Organizations | 501(c)(3) | Employees exempt from federal income tax withholding; FICA still applied. |
| Religious Organizations | 501(c)(3) | Same as above; some may claim clergy housing allowance exclusion. |
| Trade Associations | 501(c)(6) | Employees subject to full federal income tax withholding. |
| Political Action Committees | 527 | Subject to federal income tax; ADP processes standard withholding. |
Only 501(c)(3) organizations qualify for federal income tax exemption on employee wages. ADP reflects this distinction in its tax tables. Using the wrong classification leads to incorrect withholding and potential IRS penalties.
There is no "tax-exempt" option in ADP's interface that bypasses IRS approval. You cannot select a checkbox labeled "Tax Exempt" and expect the system to comply. ADP requires documentation to activate the setting.
Also, tax exemption does not eliminate recordkeeping. You must retain copies of the IRS determination letter, Form 990 filings, and minutes showing board approval of compensation. These documents are subject to audit.
Finally, tax-exempt status is not permanent. The IRS can revoke it if your organization engages in prohibited activities. For example, a nonprofit that sells merchandise to generate profit may lose exemption if profits aren't reinvested into mission work.
