Contract-to-hire is a hiring arrangement in which you work for a client company on a temporary basis, usually three to twelve months, through a staffing agency that acts as your legal employer during that trial period. If the fit works for both sides, the client offers you a permanent position at the end of the contract and takes over as your direct employer. So how does contract to hire work in practice? Three parties sign the agreement — you, the staffing agency, and the client — and each has a distinct role in your pay, your day-to-day work, and what happens when the contract wraps up.
How the Three-Party Setup Works
The staffing agency is your employer of record. It recruits you, places you at the client, runs payroll, and carries the employer-side tax and insurance obligations. The client directs your daily work at its facility but does not put you on its own payroll until conversion.
Before your first day, all three parties sign an agreement covering a handful of terms worth reading closely.
- Contract duration. Most run three to twelve months, with three to six months being the most common window. The contract may allow the client to extend the trial if it needs more time to evaluate you.
- Hourly pay rate. Your rate is fixed for the length of the contract and is often lower than a comparable permanent salary because the client is also paying the agency a markup for recruiting, payroll taxes, and administrative overhead.
- Conversion fee. When the client hires you permanently, it pays the agency a one-time buyout, typically a percentage of your projected annual salary. Many contracts reduce or waive the fee once you have been on assignment a certain number of months, which can push the client to keep you on contract longer before converting.
- Anticipated permanent salary. Some agreements list the salary the client expects to offer at conversion. It is a starting point, not a guarantee.
- No-hire clause. This prevents the client from hiring you directly, bypassing the agency, for a set period without paying a fee.
Pay attention to the job duties section too. A clear description of your responsibilities and performance benchmarks during the trial period protects you from being evaluated against goals no one told you about. If what you are actually asked to do drifts from what the contract describes, raise it with both the agency and the client early.
Your Pay and Tax Status During the Contract
You are an employee of the staffing agency, not an independent contractor. The agency withholds federal and state income taxes, deducts your share of Social Security and Medicare, and issues you a Form W-2 at year end, not a 1099.1Internal Revenue Service. About Form W-2, Wage and Tax Statement
The agency also pays the employer share of FICA (6.2% Social Security and 1.45% Medicare on your wages) and covers Federal Unemployment Tax, assessed at 6.0% on the first $7,000 of wages per employee, along with state unemployment insurance.2Internal Revenue Service. Topic No. 759, Form 940, Employers Annual Federal Unemployment (FUTA) Tax Return Workers’ compensation is the agency’s responsibility as well. If you are injured on the job at the client’s site, the agency’s policy covers the claim.
Because you are classified as an employee, you keep full Fair Labor Standards Act protections. If you are non-exempt, you are entitled to overtime at one and a half times your regular rate for every hour past 40 in a workweek.3Office of the Law Revision Counsel. 29 U.S. Code 207 – Maximum Hours The client and the agency share responsibility for honoring these rules, so if overtime goes unpaid either or both could face liability.
Health Insurance and Paid Leave During the Contract
Whether you get health coverage during the contract phase depends largely on the size of the agency. Under the Affordable Care Act, any employer with 50 or more full-time employees (including full-time equivalents) must offer coverage to workers averaging at least 30 hours per week.4Internal Revenue Service. Employer Shared Responsibility Provisions Most large national staffing agencies clear that threshold, so a full-time contract assignment generally comes with an offer of a health plan. The coverage must meet minimum value standards, covering at least 60% of average medical costs, and your share of the self-only premium is capped at a percentage of household income the IRS updates each year.
Smaller agencies with fewer than 50 full-time employees are not required to offer health insurance, though some do. If yours does not, you can buy coverage through the Health Insurance Marketplace. Losing prior coverage or starting a new job may open a special enrollment window outside the annual sign-up period.
Other benefits vary. Federal law does not require paid vacation, sick leave, or holiday pay; those are matters of agreement between you and the employer.5U.S. Department of Labor. Vacation Leave More than a dozen states and Washington, D.C., have mandatory paid sick leave laws that apply to temporary workers, with accrual typically running one hour of paid sick leave for every 30 to 52 hours worked, depending on the jurisdiction. The agency has to comply with local law regardless of what the contract says.
Discrimination Protections Apply to You
Federal anti-discrimination laws cover you even though the agency, not the client, technically employs you. Under EEOC guidance, both the agency and the client share responsibility for preventing workplace discrimination and harassment. The client can be held directly liable for its own conduct. The agency is also liable if it participates, for instance by honoring a client’s request to replace you for a discriminatory reason, or if it knew about misconduct and failed to act.6U.S. Equal Employment Opportunity Commission. Enforcement Guidance: Application of EEO Laws to Contingent Workers Placed by Temporary Employment Agencies and Other Staffing Firms
When both are found liable, they are jointly and severally responsible for back pay, front pay, and compensatory damages, meaning you can recover the full amount from either or both combined. Punitive damages are assessed individually against each entity based on its own conduct.6U.S. Equal Employment Opportunity Commission.

Converting to a Permanent Role
The move from the agency’s payroll to the client’s starts with a performance evaluation against the benchmarks set in the original agreement. If the client decides to move forward, you receive a formal offer letter covering permanent salary, bonus structure, and benefits. Signing triggers offboarding with the agency, which closes your active file.
You will complete a new Form I-9 with the client to verify your work eligibility. The client has to finish its portion of the form within three business days of your first day on its payroll.7U.S. Citizenship and Immigration Services. Completing Section 2, Employer Review and Attestation Standard internal onboarding follows: employee ID, systems access, benefits enrollment.
Health insurance and retirement plans through the client usually begin on your start date or after a short waiting period. If the agency’s coverage ends before the client’s begins, the end of your staffing assignment is a qualifying event that lets you continue the agency’s plan under COBRA, though you pay the full premium yourself.8U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers
Whether your contract hours count toward seniority, vacation accrual, or retirement plan eligibility at the client depends on the client’s internal policies. Federal rules generally require an employer to credit all years of service for retirement plan eligibility and vesting when the same employer maintains the plan, but a staffing agency and its client are usually separate, unrelated employers.9eCFR. Part 2530 – Rules and Regulations for Minimum Standards for Employee Pension Benefit Plans Ask during the offer stage whether the client will credit your contract hours.
Your final paycheck from the agency should include any accrued paid leave the agency owes you. Because federal law does not require paid leave payouts, your entitlement depends on agency policy and state law.5U.S. Department of Labor. Vacation Leave
The Tax Wrinkle When You Switch Payrolls Mid-Year
When you move from the agency to the client, each employer tracks your earnings separately. That matters most for Social Security tax. In 2026, Social Security tax (6.2% from you and 6.2% from the employer) applies only to the first $184,500 in wages.10Social Security Administration. Contribution and Benefit Base Because the agency and the client are separate employers, neither knows what the other withheld. If your combined earnings from both exceed $184,500, you may overpay Social Security tax.
If that happens, you can claim the excess as a credit on your federal income tax return. The IRS treats it as an additional tax payment that reduces what you owe or increases your refund.11Internal Revenue Service. Topic No. 608, Excess Social Security and RRTA Tax Withheld This only applies to the employee share; the employers do not get their portions back. Keep both W-2s to document the overpayment when you file.
Medicare has no wage cap, so there is no overpayment risk on that side. Income tax withholding, however, resets when you switch employers. The client starts fresh without knowing your prior earnings, which can lead to under-withholding if you do not update Form W-4 to reflect combined income. Review your withholding after the transition to avoid a surprise bill in April.
If the Client Doesn’t Hire You
A contract-to-hire arrangement does not guarantee a permanent job. If the client decides not to convert you, the outcome depends on your agreement and the agency’s policies. Some agencies will try to place you in a new assignment. Others simply end the relationship when the contract expires.
If no new assignment materializes and you are out of work, you may qualify for unemployment benefits. The end of a temporary assignment generally counts as a layoff rather than a voluntary quit, which is typically the threshold for eligibility. Each state runs its own program with different rules on qualifying wages, waiting periods, and benefit amounts, so file with your state’s unemployment office promptly.
The agency is usually the employer of record for unemployment purposes, so the claim is filed against the agency, not the client. The agency paid unemployment insurance on your wages throughout the contract, which is what funds the system. If the agency offers you a comparable new assignment and you turn it down without good cause, that refusal can affect your eligibility in most states.
