Does Workers’ Comp Cover Lost Wages in Illinois?

A work injury often brings two worries at once: getting medical care, and paying the bills while you cannot work. Illinois workers’ compensation addresses both. This guide focuses on the second one: whether you qualify for lost-wage benefits, which benefit fits your situation, when payments should start, and what to do if they do not arrive.

This article covers who qualifies and how to get paid. If you want to estimate the dollar amount of your check, see How Much Does Workers’ Comp Pay in Illinois?, which walks through the calculation with examples.

Does Illinois Workers’ Comp Pay for Lost Wages?

Yes, for wage loss caused by a work-related injury or illness. Workers’ compensation in Illinois is a no-fault system, so you do not need to prove your employer was at fault. A covered work injury may entitle you to medical care. Wage-replacement benefits may also be available when the injury prevents you from working or causes qualifying reduced earnings, which you show through medical evidence of your restrictions. If you are unsure whether your injury counts, see what qualifies as a work-related injury.

Lost-wage benefits are partial wage replacement. Total disability benefits pay two-thirds of your gross average weekly wage, up to a weekly maximum set by the Illinois Workers’ Compensation Commission. Because the payments are not taxed, the gap from your normal take-home pay is often smaller than it sounds.

When Do You Qualify for Lost-Wage Benefits?

You generally qualify when your doctor says you cannot work because of the work injury, or releases you to restricted work that your employer cannot provide. According to the IWCC handbook, TTD is paid when an employee is temporarily unable to return to any work as indicated by a doctor, and it continues until the employee returns to work or reaches maximum medical improvement. Three things usually need to line up:

• A work-related injury, reported to your employer. Illinois requires notice within 45 days of the accident; our article on when to report a work-related injury explains why sooner is better.
• Medical restrictions, documented by your treating doctor, showing you are off work or limited to certain duties.
• Actual wage loss caused by those restrictions, either because you are not working or because you are earning less.

How Many Days Must You Miss Before Workers’ Comp Pays?

Under Illinois’ waiting period, the IWCC handbook states that TTD is not paid for the first three lost workdays unless the employee misses 14 or more calendar days because of the injury. In practice:

• Miss three workdays or fewer: no TTD for those days, though your medical treatment is still covered.
• Miss more than three workdays but fewer than 14 calendar days: TTD starts on the fourth lost workday.
• Miss 14 or more calendar days: TTD is owed from the first lost workday, including the original three.

The waiting period is about which days are payable. It is separate from when the first check should actually arrive, which is covered next.

When Should Your First Workers’ Comp Check Arrive?

The IWCC says the employer should make the first TTD payment within 14 days after receiving notice of the injury. The handbook also encourages injured workers to give the employer a written demand for TTD benefits along with the doctor’s note. A written request creates a dated record of when the employer had what it needed to start paying, which matters if payments are late.

Benefits are paid at the same interval as your wages were before the injury. If you were paid weekly, TTD should generally come weekly; if every two weeks, every two weeks. The handbook does not guarantee an exact arrival date, and insurers sometimes take longer to investigate, so keep copies of everything you send.

How Do You Document and Request Lost-Wage Benefits?

Report the injury, get your restrictions in writing from your doctor, and send them to your employer with a written request for TTD. Complete records help the insurer act on your claim and give you evidence if payments are delayed. Keep a file with:

• Medical off-work notes and restrictions from every visit, including any changes.
• Injury report and notice records, showing when and how your employer learned of the injury.
• Pay stubs and wage statements for the year before the injury, which determine your rate.
• Dates of missed work or reduced hours, recorded as they happen.
• Written light-duty offers and your actual earnings in any light-duty job.
• Payment records and insurer letters, including any explanation for a denial or a reduced amount.

Then request benefits in writing:

1. Give your employer written notice of the injury if you have not already done so.
2. Send your doctor’s off-work or restriction note to your employer and the insurance adjuster.
3. Include a short written request that TTD (or TPD, if you are on reduced-pay light duty) be paid.
4. Keep a copy and note the date it was sent.
5. Follow up in writing if no payment arrives within 14 days.

Request the wage statement and an explanation of your rate in writing, and keep copies of your correspondence. If you speak with the adjuster by phone, our guide on what not to say to the workers’ comp adjuster explains what to keep in mind. Medical documentation is the backbone of any wage claim; see what medical evidence you will need.

What If Your Employer Cannot Offer Suitable Light Duty?

A release to light duty does not automatically end TTD. If your employer cannot accommodate your temporary restrictions, you may remain eligible while you recover. The IWCC handbook treats a worker whose temporary restrictions cannot be accommodated as eligible for TTD. Two documents matter most here:

• The restriction note. It should state your limits clearly, such as no lifting over 20 pounds or seated work only.
• The job offer, or the absence of one. If your employer offers light duty, ask for it in writing with the duties described, so you and your doctor can confirm it fits your restrictions.

If a suitable light-duty job is offered at lower pay than your regular job, TPD generally makes up two-thirds of the difference. For example, if your regular job would pay $1,000 a week and light duty pays $700, TPD would be two-thirds of $300, or $200 a week. The payment calculation guide has more examples. A functional capacity evaluation is sometimes used to set longer-term restrictions.

What If Workers’ Comp Payments Are Late, Denied, or Stopped?

Ask for the reason in writing, preserve your records, and send a written demand with your medical support. If the insurer still does not pay, you can ask the Commission to review the claim. Possible reasons for a stopped or delayed payment include a gap in medical documentation, a dispute over whether the injury is work-related, a report from an employer-chosen doctor, or a claim that light duty was available. Steps to take:

1. Request the reason in writing. Ask the adjuster which document or decision ended or delayed your payments.
2. Close any medical gap. Make sure every period you missed is covered by a current off-work or restriction note.
3. Send a written demand for the unpaid benefits, attaching the medical support.
4. Keep everything. Dated copies of letters, emails, and payment records are your evidence of the delay.
5. Seek review. If benefits remain unpaid, you can file a claim or a petition with the Illinois Workers’ Compensation Commission.

Unpaid TTD that you were owed can generally be recovered as back pay once the dispute is resolved. The IWCC handbook also explains that if an employer does not pay promptly and cannot justify the delay, the employee may petition the arbitrator for penalties and attorney’s fees under Sections 16, 19(k), and 19(l) of the Act. Penalties are not automatic; they depend on whether the delay was unreasonable.

If your medical bills are being paid but your wage checks are not, or the reverse, see what happens to medical bills when workers’ comp is denied and whether you can appeal a denied workers’ comp claim.

How Long Do Lost-Wage Benefits Continue?

TTD generally continues until you return to work or reach maximum medical improvement (MMI). There is no fixed number of weeks; it is tied to your medical status. MMI means further treatment is not expected to improve your condition. Reaching MMI does not necessarily mean you have recovered fully or can return to your former job, which is why the claim generally moves to a permanent phase:

• If you can return to your old job, temporary benefits end and any permanent loss of use is valued and usually resolved by settlement or award.
• If you cannot return to your old job, you may qualify for vocational rehabilitation with maintenance benefits paid at no less than your TTD rate, and later a wage differential award if your earnings are permanently reduced.
• If you cannot work in any stable job market, permanent total disability pays two-thirds of your average weekly wage for life.

Frequently Asked Questions About Lost Wages

Do you get paid on workers’ comp in Illinois?

Yes, if your work injury keeps you from working or reduces your earnings. For TTD, the waiting-period rules apply: the first three lost workdays are paid only if you miss 14 or more calendar days. Payments usually come from your employer or its insurer, not from the state. If an employer was uninsured, the state’s Injured Workers’ Benefit Fund may be an option.

Does workers’ comp pay all of my lost wages?

Usually not. TTD generally pays two-thirds of your gross average weekly wage, subject to minimums and maximums. The maximum is $2,045.63 a week for injuries from July 15, 2026 through January 14, 2027. For some lower-wage workers, the minimum benefit rule can result in payment equal to their average weekly wage. Because the payments are not taxed, they usually replace more of your take-home pay than the two-thirds figure suggests.

Does workers’ comp pay for the first three days off?

Only if you end up missing 14 or more calendar days because of the injury. If you return to work sooner, the first three lost workdays are not paid.

Why are my medical bills being paid but not my lost wages?

Medical benefits and wage benefits are handled separately. Possible reasons include the insurer not having an off-work or restriction note covering the missed time, or a belief that light duty was available. Send your doctor’s notes with a written TTD request.

Can I get back pay if workers’ comp starts paying late?

Generally yes. TTD you were entitled to is still owed for the period you were off work. Where a delay was unreasonable, the Commission can also award penalties and attorney’s fees.

Do I have to use vacation or sick time after a workplace injury?

It depends on your employer’s policies and any union agreement. Using paid time off can affect how your TTD is paid for those days, so ask how it will be handled before you agree, and keep records of what was used.

Does workers’ comp cover time off for doctor appointments?

It depends on the appointment. If your employer sends you to a medical examination it requested, the IWCC handbook states that the employer must reimburse the wages you lose and your travel and meal expenses. For appointments with your own doctors, coverage depends on the facts, including whether you are still working and how the time was paid. Keep a record of appointment dates and any lost pay, and raise it with the adjuster or your attorney rather than assuming it is covered or excluded.

Are lost-wage benefits taxable?

Generally no. The IWCC handbook states that workers’ compensation benefits are not taxable under state or federal law, consistent with IRS Publication 525. Wages you earn on light duty remain taxable.

Does workers’ comp cover lost wages after a car accident on the job?

It can, if you were driving for work at the time. See when a car accident qualifies for workers’ compensation.
