Updated July 2026
Arizona employers must collect seven forms and complete several compliance actions for every new hire — including Form I-9, E-Verify verification, new hire reporting, federal and state withholding forms, a health coverage notice, and relevant benefit enrollment documents. Requirements have changed since 2023. Most notably, Arizona expanded its E-Verify obligations as of 1 January 2026 to cover certain labour and services contracts, not just direct employment. This checklist covers every step in the correct order, with 2026-accurate timelines.
1. Form I-9 (Employment Eligibility Verification)
Every new employee must complete Section 1 of Form I-9 no later than their first day of work. The employer must complete Section 2 within three business days of the hire date.
The completed I-9 must be retained for each active employee. Once employment ends, keep the form for either three years from the date of hire or one year after termination — whichever is later.
Store I-9 forms separately from personnel files. I-9 audits occur regularly, and keeping them in a dedicated folder speeds up any compliance review significantly.
Always use the current USCIS version of Form I-9. Check USCIS.gov when updating your onboarding packet, as the form version changes periodically and using an outdated version creates compliance risk.
2. E-Verify (Arizona Requirement — Updated January 2026)
Arizona requires employers to run all new hires through E-Verify in addition to completing Form I-9. E-Verify supplements the I-9 — it does not replace it.
Important 2026 change: As of 1 January 2026, Arizona expanded E-Verify obligations to include certain labour and services contracts. If you enter into a contract for labour or services valued at $600 or more, you may now be required to verify those workers through E-Verify, even if they are not direct employees. Review any contractor or service agreements against the updated Arizona guidance and update your procurement and onboarding checklists accordingly.
Complete E-Verify verification within three business days of the hire date and retain all case records per federal and state record keeping requirements.
If you work with a HR outsourcing partner, confirm in writing whether they run E-Verify on your behalf — and check whether the new contractor threshold affects any of your current service agreements.
3. New Hire Reporting to the Arizona New Hire Reporting Center
Federal and state law requires employers to report every newly hired or rehired employee — including part-time and temporary workers — to the Arizona New Hire Reporting Center within 20 days of the hire date.
You can report online via the Arizona New Hire Reporting Centre or use the electronic upload option. Required data includes your FEIN, employer name and address, and each employee’s full name, Social Security Number, hire date, and home address.
4. Form W-4 (Federal Income Tax Withholding)
Every new employee must complete a Form W-4 before their first paycheck so you can calculate the correct amount of federal income tax to withhold.
Always use the current version of Form W-4 from IRS.gov. Update your onboarding packet whenever the IRS issues a new version — using an outdated form can cause withholding errors that create problems for both the employer and the employee at tax time.

5. Arizona Form A-4 (State Income Tax Withholding)
Every new employee must complete Arizona Form A-4 before their first payroll run so you can calculate the correct Arizona state income tax withholding.
Confirm you are using the current A-4 version from the Arizona Department of Revenue. The form has been revised in recent years and older versions may produce incorrect withholding amounts.
6. Notice of Coverage Options (ACA Health Coverage Notice)
Federal law requires employers to provide a Notice of Coverage Options to new employees. There are two templates: one for employers who offer a group health plan, and one for employers who do not.
The purpose of this notice is to inform employees about their health insurance options, including the Healthcare.gov Marketplace. Template language and administration have evolved since the ACA was introduced — use the current Department of Labour or CMS templates, or your benefits broker’s current version, to ensure compliance.
If you offer a group plan, also provide plan enrollment materials and written confirmation of any waiting period or eligibility rules. Our team can help with employee benefits administration if managing this in-house is becoming complex.
7. Benefit Enrollment and Additional Onboarding Documents
Beyond the six required forms above, a complete new hire packet should include:
- Direct deposit authorization — bank details and payroll setup
- Employee handbook acknowledgement — signed confirmation the employee has received and read your handbook
- Harassment and discrimination policy notice — required under federal and Arizona law
- Workers’ compensation information — Arizona employers must notify employees of their workers’ compensation coverage
- Benefit enrollment forms — health, retirement, and any other benefits, with eligibility dates clearly stated
- Required workplace posters notice — or provide copies of current federal and Arizona state workplace posters
2026 Compliance Tips for Arizona Employers
Audit your forms annually. The I-9 version, W-4, A-4, and health coverage notice templates all change. Review your onboarding packet at the start of each year and any time a federal or state agency issues an updated form.
Review contractor relationships now. The 2026 E-Verify expansion to labour and services contracts valued at $600 or more is the most significant compliance change this year for Arizona employers. If you use contractors or engage service providers directly, check whether any of those arrangements now trigger an E-Verify obligation.
Centralize and secure your I-9s. Keep them separate from personnel files, store them securely, and make them easy to retrieve in the event of an audit.
Confirm your PEO or payroll provider’s responsibilities in writing. If you work with a PEO, confirm whether they file new hire reports, run E-Verify, and maintain I-9 records on your behalf. Get this confirmed in writing. See our HR outsourcing FAQs for more on what a PEO handles versus what stays with the employer.

Frequently Asked Questions
