US employment contracts: what must be included
Reviewed by Mellow Editorial Team, HR & payroll content team
A US employment contract does not need to follow a single federal template, but certain terms are worth including in every agreement to protect both employer and employee. While at-will employment means either party can usually end the relationship at any time, a well-drafted contract sets clear expectations and reduces the risk of disputes.
What the law does — and does not — require
There is no federal law mandating a written employment contract for most private-sector workers. Employment is generally at-will across the US, meaning you can terminate an employee (and they can resign) at any time, for any lawful reason or no reason at all, unless a contract says otherwise.
That said, certain disclosures are legally required in other forms. Employees must receive a Form W-4 to capture withholding preferences before their first paycheck. By January 31 each year, you must issue a Form W-2 covering the prior tax year. Neither of these is part of the contract itself, but they are part of the employment relationship you are creating.
State law adds another layer. Some states require written wage notices at hire — New York is a well-known example. Always check the rules in every state where you have employees before finalizing any agreement.
Core terms every contract should cover
Even if you rely on at-will employment, a written agreement should address:
Job title and duties. A clear description of the role and reporting structure. This does not need to be a full job spec, but vague language causes problems when performance issues arise.
Compensation and pay schedule. State the base salary or hourly rate, how often pay is issued (weekly, bi-weekly, semi-monthly), and the method of payment. If the role includes bonuses or commissions, describe how they are earned and when they are paid. Ambiguity here is a common source of wage claims.
At-will status (if applicable). If you want to preserve at-will employment, say so explicitly. Some courts have found that contract language around "cause" for termination or defined notice periods modifies at-will status — so be deliberate about what you include.
Benefits summary. Health insurance, retirement plan participation, and any paid time off should be referenced, even if the full detail lives in a separate plan document. There is no federal mandate for paid annual leave or paid sick leave, but if you offer these, specify the accrual method and any carryover rules.
Confidentiality. Employees routinely handle sensitive information — customer data, pricing, trade secrets. A confidentiality clause should survive termination and be specific about what it covers.
Intellectual property assignment. Any work product created in the course of employment should belong to the company. State this clearly, and note any carve-outs your state requires (California, for instance, has statutory limits on what employers can claim).
Non-competes: tread carefully
Non-compete clauses are one of the most legally variable areas in US employment law. California prohibits most non-compete clauses outright, and several other states have significantly restricted their use or require additional consideration beyond continued employment for them to be enforceable. The FTC attempted a near-total federal ban in 2024, though that rule faced ongoing legal challenges.
If you operate in multiple states, a clause that is enforceable in Texas may be void in California. The safer approach is to rely on well-drafted confidentiality and non-solicitation clauses, which tend to hold up better across jurisdictions, and to take specific legal advice on any non-compete language you want to include.
Contractor versus employee: keep contracts consistent with reality
How you classify a worker matters more than what you call them in a contract. If someone is labeled an independent contractor but works set hours, uses your equipment, and is supervised day-to-day, courts and agencies may treat them as an employee regardless of what the agreement says. Misclassification exposes you to back taxes — including the employer's share of FICA (Social Security at 6.2% up to the wage base, plus Medicare at 1.45%) — as well as penalties and potential benefit claims.
For genuine contractors, use a separate contractor agreement rather than adapting an employment contract. The key reporting obligation is Form 1099-NEC, issued by January 31 for any contractor paid $600 or more in the calendar year.
Practical steps before you finalize any agreement
- Have an employment attorney review the contract, particularly if you operate in California, New York, or other states with complex employment laws.
- Keep a signed copy on file and give the employee a copy at signing.
- Update agreements when roles change materially — a contract written for a junior hire may not reflect the responsibilities of someone promoted two years later.
- Treat offer letters and handbooks as part of the same picture. Contradictions between documents create ambiguity that employees' lawyers will exploit.
If you are hiring across multiple states or countries, consider how your standard contract template holds up in each jurisdiction before you extend an offer. What works in one state may need meaningful revision fifty miles away.
