Offboarding well in the United States
Reviewed by Mellow Editorial Team, HR & payroll content team
Offboarding an employee well protects your business legally, preserves your reputation as an employer, and keeps sensitive data secure. Done poorly, it creates compliance gaps, potential litigation, and operational disruption.
Start with the legal basics before the last day
As soon as a departure is confirmed — whether voluntary or involuntary — check your state's final paycheck rules. Federal law does not set a deadline for the final paycheck beyond the next regular payday, but many states impose stricter timelines. California, for example, requires payment on the last day of work for terminations. Violation of these rules can trigger penalties, so confirm the rule in every state where the employee works.
At the same time, issue the required COBRA notice. Under federal law, employees who lose group health coverage have the right to continue it at their own expense. You have 14 days from the qualifying event to provide the election notice. Missing this window exposes you to excise taxes and potential lawsuits.
If the termination is involuntary, document the reason clearly and consistently. Because employment in the United States is generally at-will, you can end most employment relationships without cause — but inconsistent documentation is one of the most common triggers for wrongful termination claims.
Recover company property and revoke system access
Create a physical and digital checklist before the employee's last day. Physical items typically include laptops, phones, access badges, corporate cards, and any equipment issued for remote work. Digital access is equally important and easier to overlook.
Work with IT to revoke access to email, internal systems, cloud storage, and any third-party tools (Slack, GitHub, Salesforce, and so on) on or before the final hour of the last day. For sensitive roles — finance, HR, engineering with production access — revoke access before the exit conversation happens, not after.
Transfer ownership of files, email accounts, and ongoing work before access is cut. An inbox left in limbo for weeks causes real operational damage.
Run the final payroll correctly
The final paycheck must include all hours worked through the last day, any overtime owed, and — depending on your state and written policy — accrued unused vacation. Some states (again, California is the clearest example) treat accrued vacation as earned wages, meaning you cannot forfeit it regardless of what your PTO policy says. Other states follow the employer's written policy.
Commissions and bonuses due under a signed agreement must also be paid according to the terms of that agreement. Review any commission plan carefully — if payment depends on a future event (a deal closing after the employee leaves), the plan's language controls what you owe.
For payroll tax purposes, the final paycheck is processed the same as any other: federal income tax withheld based on the employee's Form W-4, Social Security at 6.2% up to the annual wage base, and Medicare at 1.45% with no cap. You match Social Security and Medicare as the employer.
The W-2 for the year must reach the former employee and the Social Security Administration by January 31 following the tax year in which they were paid.
Conduct an exit interview and protect confidential information
Exit interviews are optional, but they generate useful data on retention, management issues, and gaps in compensation or benefits. Keep them structured and short — 20 to 30 minutes. Use consistent questions so you can identify patterns over time. The information is only useful if someone reviews it and acts on it.
Separately, remind the departing employee — in writing — of any continuing obligations they signed: non-disclosure agreements, non-solicitation clauses, and IP assignment agreements. Be specific about what information remains confidential and for how long.
Note that non-compete clauses are largely unenforceable in California and face increasing restriction in other states. The FTC's regulatory activity in this area continues to evolve, so if your agreements contain non-compete language, have counsel review their enforceability in the relevant state before you rely on them.
Update your internal records and communicate clearly
Once the employee has left, update your org chart, payroll records, and benefits administration. Remove the individual from your 401(k) plan participant list if applicable, and notify your benefits broker.
Communicate the departure to the team promptly and factually. You do not need to share reasons. A simple statement that the person has left and who will cover their responsibilities is enough. Silence or a prolonged vacuum invites speculation and damages morale.
Finally, preserve employment records according to federal retention requirements. EEOC guidelines generally call for personnel records to be kept for one year after termination; payroll records under FLSA should be kept for at least three years. State rules may be longer — check the requirements for each state where you operate.
