A job offer letter is the written version of an employer's offer. In the US it usually states the job title, pay, start date, manager, and a deadline to respond, and it often says the job is "at will" and that the offer depends on conditions such as a background check. It is usually shorter and less binding than a formal employment contract, but what it says still matters, so read every line before you sign.
This guide walks through a typical letter clause by clause, explains at-will language and common contingencies, gives you a checklist to use before signing, and ends with a labeled sample letter.
What a US offer letter usually contains
UC Berkeley's career center says a written offer should list the title, salary, start date, supervisor, and response deadline, and should tell you if the offer depends on a background check or drug screening. Most letters include more than that. Here is what you are likely to see and what to look for in each part.
| Section | What it says | What to check |
|---|---|---|
| Position | Title, department, manager, full-time or part-time | The title matches the posting and what you discussed |
| Classification | Exempt (salaried, no overtime) or nonexempt (eligible for overtime) | If you will work long weeks, this affects your real hourly pay |
| Compensation | Base pay, pay frequency, bonus or commission | Whether a bonus is guaranteed or a "target," and how it is decided |
| Equity | Stock options or units, often "subject to board approval" | Number of shares, vesting schedule, and that the separate equity agreement controls |
| Benefits | Health plan, retirement plan, paid time off | When coverage starts; letters often refer you to plan documents |
| Location and schedule | Office address, remote or hybrid terms, hours | Required office days stated plainly |
| Start date | A proposed first day | Room for your notice period at your current job |
| At-will statement | Either party can end employment at any time | Whether anything else in the letter contradicts it |
| Contingencies | Background check, references, drug test, license verification, work authorization | Which ones apply and what happens if one is delayed |
| Other agreements | Confidentiality, invention assignment, non-solicitation, noncompete, arbitration | Ask to see these before you accept, not on day one |
| Deadline | The date your signed acceptance is due | Time to ask questions or negotiate |
If benefits details are missing, Berkeley suggests asking for them before you decide. That is a normal request, not a red flag.
What "at-will" language means
Most US offer letters include a sentence like "Your employment with the Company is at will." Cornell's Legal Information Institute explains that at-will employment has no set period, and either the employer or the employee can end it at any time for almost any reason, as long as the reason is not illegal. Firing someone for a discriminatory reason, or in retaliation for certain protected actions, is still unlawful.
What this means for you in practice:
- You can leave without breaking a contract, though professional norms still favor giving notice.
- The employer can end your job, including during a probation or introductory period, generally without needing a reason.
- Promises outside the letter are weak. "You'll have a job here for years" during an interview generally does not override at-will language in writing. Many letters say outright that the letter is the complete offer and replaces any earlier discussions.
- State rules vary. Some states recognize exceptions, such as implied contracts or good-faith limits. Montana is the clearest outlier: its Wrongful Discharge from Employment Act treats a firing as wrongful if it was not for good cause and the employee had completed the employer's probationary period. Check your state if this matters to you.
Common contingencies and your rights
A contingent offer means the job depends on something still to happen. These are the ones you will see most often.
Background checks
If the employer uses an outside screening company, the federal Fair Credit Reporting Act applies. The Federal Trade Commission says employers must get your written permission before running the check. If something in the report might lead them to withdraw the offer, they must first give you a copy of the report and a "Summary of Rights," which gives you a chance to correct errors. Some states and cities add limits on criminal history or credit checks, so check local rules too.
Medical exams and health questions
Under the Americans with Disabilities Act, employers generally cannot ask disability-related questions or require medical exams before making a conditional offer. After a conditional offer, the EEOC says an employer may ask disability-related questions or require a medical exam, as long as everyone selected for the same job is asked the same questions or given the same exam. This is why a physical or health questionnaire often shows up only after the offer letter.
Proof of work authorization
Every new hire in the US completes Form I-9. USCIS says the employer must complete its section within three business days of your first day of paid work. You choose which acceptable documents to present: one from List A, or one from List B plus one from List C. An offer letter that demands a specific document, such as only a passport, is worth asking about.
References, licenses, and degrees
Letters often say the offer depends on satisfactory references or verification of a degree or professional license. If your license is pending or transferring from another state, tell the employer now and ask for the timeline in writing.
Restrictive covenants: noncompete and related clauses
Some offers come with a separate agreement limiting what you can do after you leave. The Federal Trade Commission's 2024 rule banning most noncompetes never took effect. The FTC's own page now says the rule is not in effect and is not enforceable, so noncompete agreements are governed by state law, which differs widely. A few states sharply limit noncompetes and others enforce them if they are reasonable in time and scope. If a noncompete, non-solicitation clause, or arbitration agreement could affect your next move, ask to see it before you accept and consider having an employment lawyer in your state review it.
Checklist before you sign
- The title, manager, and department match what you discussed.
- Base pay is stated as a number per year or per hour, separate from any bonus.
- Bonus, commission, or equity terms say whether they are guaranteed or discretionary.
- Exempt or nonexempt status is stated.
- Remote, hybrid, or on-site terms are spelled out, including office days.
- The start date leaves room for your notice period.
- Every contingency is listed, and you know who runs each check.
- Any separate agreements (confidentiality, noncompete, arbitration) have been shared with you.
- Anything promised on a call that matters to you appears in writing.
- You know the response deadline. UConn's career center notes companies often allow 2 to 10 business days.
If something is missing or wrong, it is reasonable to reply, thank them, and ask for a corrected letter.

Signs an "offer letter" may be a scam
Fake job offers are common enough that the FTC has a page on them. Be cautious if an offer arrives without a real interview, comes from a personal email account, or asks you to pay anything. The FTC says honest employers do not charge you to get hired, and no honest employer will send you a check to deposit and then ask you to send part of the money back. Verify the company and recruiter through the company's own website before sharing your Social Security number or bank details for payroll.
