An offer letter confirms the headline terms and points at everything consequential — the bonus plan, the equity agreement, the handbook, the benefits summary. Read the exempt or non-exempt classification, the bonus eligibility conditions, any repayment clause attached to a signing bonus, and any restrictive covenant. Anything agreed verbally that is not in the letter should be added before you sign, because afterwards it is a conversation rather than a term.
What an offer letter usually is
An offer letter is a short document doing two jobs at once, and understanding the split explains most of what confuses people about it. It confirms the headline terms — job title, start date, salary, reporting line — and it references a set of other documents where the consequential detail actually lives.
It is also, in most US employment, an at-will document. That language means either side can end the relationship at any time for any lawful reason, and it is standard rather than a warning sign. Almost every US offer letter contains that language somewhere. It is worth understanding rather than worrying about, because it frames everything else in the letter.
What the letter is not is a complete statement of your terms. The bonus plan, the equity agreement, the benefits summary and the employee handbook are separate documents, and they contain the conditions that will matter to you in year two. That is exactly why anything agreed verbally needs to be written into the letter itself. Referenced documents can also change while the letter stays the same.
The lines to check first
Start with the classification, which is one word and decides a great deal. Exempt or non-exempt determines whether you are owed overtime, and a misclassification here is worth real money over a year of long weeks.
Then the pay basis. An annual salary, a monthly figure, an hourly rate and a weekly rate imply different things about how you will be paid and about what happens in a partial period, so confirm the letter says what you expect it to say. Mismatches here are usually clerical and worth catching early.
Then the start date and any conditions attached to it. And then the bonus line, which is where most of the ambiguity in a typical offer sits — a bonus described as a target is not the same thing as one described as guaranteed, and the difference is usually thousands of dollars a year. Read the eligibility conditions attached to it as well.
What is frequently missing and should not be
Verbal agreements are the big one. A promised review at six months, an agreed remote arrangement, a title change after probation, a start date accommodation, pay protection if you relocate — all of these get discussed and then omitted from the letter, usually without anyone intending to leave them out. Letters get generated from templates rather than written fresh.
The rule is simple and worth applying without exception. If it was agreed and it is not in the letter, ask for it to be added or confirmed in a written amendment. Somebody who agreed to it verbally will rarely object to writing it down, and somebody who does object has told you something important about the arrangement. Take that seriously rather than explaining it away.
The reason this matters is not distrust. It is that the person who made the promise may not be there in eighteen months, and an undocumented arrangement dies with the relationship that created it. Writing it down is protection against turnover rather than against bad faith.
The clauses that constrain you afterwards
Restrictive covenants deserve a careful read even though they sit at the back. Non-solicitation clauses frequently cover former colleagues as well as clients, which surprises people who read them as being only about customers. Recruiting a former teammate can breach a clause you forgot signing.
Non-compete provisions vary enormously in enforceability by state, and several states substantially restrict or prohibit them. That variation is worth checking against where you actually work rather than assuming either that it is unenforceable or that it binds you completely. The answer depends on where you work rather than on how the clause reads.
Intellectual property assignment clauses matter to anybody who writes, builds or invents outside work. Some are drafted broadly enough to capture personal projects, and narrowing that language is a normal request that employers grant more often than people expect. Most have no interest in your weekend projects at all.
Contingencies worth reading properly
Most offers are conditional on something, and most of those conditions are routine. Background checks, reference checks and proof of eligibility to work are standard and rarely cause any problems at all. They are worth reading only to know what is outstanding.
What is worth noticing is the timing. A conditional offer that you accept before the conditions clear means resigning from a current job against something that could still fall through, and that sequence is a genuine risk rather than a theoretical one. People are caught by it every year.
Where you can, get the conditions cleared before you resign. Where you cannot, at least know which conditions are outstanding and how long they typically take, so that you are choosing the risk rather than discovering it later. Knowing the timeline is most of the protection.
The sign-on conditions
Signing bonuses almost always carry a repayment clause, and the terms vary more than people check. Read the period — commonly one or two years — and read whether repayment is triggered by resignation only or by termination for cause as well. Those two versions behave very differently if things go wrong.
Read whether the repayment is calculated on the gross amount or the net. A gross repayment clause on a bonus you received after tax means repaying more than you actually got, which is a genuinely unpleasant discovery to make in month ten. Ask which basis applies before you sign anything.
Relocation assistance frequently carries the same structure and the same trap. And since 2026, employer-paid relocation is taxable wages for civilian employees, which makes the question of whether the package is grossed up the decisive one rather than a detail buried in the package. Ask directly whether the relocation figure is grossed up.
What to do with something you disagree with
Raise it before signing, once, in writing, and specifically. Asking to narrow an intellectual property clause, shorten a repayment period or add an agreed term is an ordinary request at this stage and a difficult one afterwards. The document is settled the moment you sign it.
Employers amend offer letters routinely and the process is usually quicker than candidates fear. What they will not do is amend it after you have signed, because at that point the document is settled and the request becomes a negotiation you have no leverage in. Everything you wanted changed has to be changed beforehand.
Also notice how the request is received, because that is information about the employer. A reasonable amendment handled quickly says one thing about how the organization works, and resistance to writing down something already agreed says another.
Before you sign
Ask for the documents the letter references rather than signing against summaries of them. The bonus plan, the equity agreement, the benefits summary and the handbook are the places the real conditions live, and requesting them is entirely normal at this stage. Any employer who hesitates is worth a second thought.
Save a copy of everything outside any company system, including the letter itself and the email thread around it. You will lose access to a company account on your last day, and that is precisely when these documents matter most to you. Save them somewhere personal on the day you receive them.
And if the letter carries a restrictive covenant that could affect where you work next, or a repayment clause running a year or more, an hour with an employment lawyer is the cheapest insurance available on the whole transaction. This is general information about how these documents are structured rather than legal advice, and enforceability in particular turns on your state and your specific circumstances.
Common questions
What is an offer letter actually doing?
Confirming headline terms — title, start date, salary, reporting line — and referencing other documents where the consequential detail lives, such as the bonus plan, equity agreement and handbook.
Which line should I check first?
The exempt or non-exempt classification. It is one word and decides whether you are owed overtime, which is worth real money across a year of long weeks.
What is usually missing?
Anything agreed verbally — a six-month review, a remote arrangement, a title change after probation. If it was agreed and is not in the letter, ask for it in writing.
Why does that matter if I trust them?
Because the person who made the promise may not be there in eighteen months, and an undocumented arrangement dies with the relationship that created it.
What do restrictive covenants cover?
Non-solicitation often covers former colleagues as well as clients. Non-compete enforceability varies enormously by state. IP assignment can be broad enough to capture personal projects.
What should I check in a signing bonus clause?
The repayment period, whether repayment is triggered by resignation only or by termination for cause too, and whether it is calculated on the gross or the net amount.
What about relocation assistance?
Same structure and same trap. Since 2026 employer-paid relocation is taxable wages for civilians, so whether the package is grossed up is the decisive question.
When should I raise a disagreement?
Before signing, once, in writing and specifically. Employers amend letters routinely beforehand and will not afterwards, when you have no leverage left.
