llinois law does not create a separate “unpaid maternity leave” statute. Instead, the requirement comes from two overlapping legal frameworks:
- Federal FMLA guarantees up to 12 weeks of unpaid, job‑protected leave for qualifying employees.
- Illinois Family Leave Act (IFLA) mirrors the federal standard, also offering up to 12 weeks of unpaid leave for employees who meet state‑specific eligibility criteria.
Both laws run concurrently, meaning the 12‑week clock does not reset if you qualify under both. If you are eligible under both, you still receive a single 12‑week block of leave, but you may draw from state‑funded paid benefits (PFML) or employer benefits during that period.
When does the 12‑week period start?
The clock begins on the first day you take leave for a qualifying reason—typically the day you start your pregnancy‑related absence (e.g., prenatal bed rest, delivery, or recovery). If you take intermittent leave (e.g., a few days each week), the weeks are counted as calendar weeks, not working days.
What about extensions?
Illinois does not automatically extend the statutory 12 weeks. However, you may request additional unpaid time under the Americans with Disabilities Act (ADA) if a medical condition qualifies as a disability, or you can negotiate an unpaid extension with your employer. Some employers voluntarily offer up to 18 weeks of paid parental leave, but that is a benefit, not a legal requirement.
Does Illinois have a paid family leave program for new mothers?
Yes. Beginning January 1 2024, Illinois launched the Paid Family Leave (PFML) program, funded by a payroll tax on employers (0.5 % of the first $68,000 in wages per employee). The program is administered by the Illinois Department of Insurance and is available to any employee who meets the qualifying criteria—regardless of employer size.
For new mothers, PFML counts as a **bonding** reason, allowing you to receive a weekly benefit while you’re on leave. The benefit amount is calculated as a percentage of your average weekly wage, up to a maximum set annually by the state. As of 2026, the maximum weekly benefit is $1,300, representing roughly 70 % of the state’s average weekly wage.
How much of my salary can I expect?
PFML replaces a portion of your earnings as follows:
- 60 % of your average weekly wage for the first 6 weeks.
- 70 % of your average weekly wage for weeks 7‑12.
- Both percentages are capped at the state‑set maximum benefit ($1,300 per week in 2026).
If your regular earnings exceed the cap, you will see a shortfall. Many women combine PFML with accrued PTO or short‑term disability to fill that gap.
Eligibility criteria for Illinois maternity leave under the Family and Medical Leave Act
The federal FMLA sets a national baseline, but it’s essential to know the specific thresholds that determine whether you qualify:
- Employer size: The employer must have 50 + employees within a 75‑mile radius.
- Employment duration: You must have worked for the employer for at least 12 months (the months don’t have to be consecutive).
- Hours worked: At least 1,250 hours in the 12 months preceding the start of leave.
- Qualifying reason: Pregnancy, childbirth, or a serious health condition related to pregnancy.
If you meet all four criteria, you’re covered by both FMLA and IFLA, giving you a solid safety net. Employees who fall short on any of these metrics may still be eligible for PFML, which has a lower threshold (no minimum hours required) but does not guarantee job protection.
Part‑time workers and leave eligibility
Part‑time employees can qualify if they meet the 1,250‑hour rule. For example, a part‑timer working 25 hours per week for 50 weeks will meet the threshold. However, many part‑time staff fall short of the required hours, which means they may rely solely on PFML for wage replacement and must negotiate any job protection directly with their employer.
How to apply for maternity leave in Illinois and required documentation
Getting your paperwork in order can feel like navigating a maze, but a clear roadmap helps you stay on track. Below is a step‑by‑step guide that most employees follow, illustrated by “Jenna,” a 28‑year‑old teacher who successfully secured her leave two months before her due date.
- Notify your employer in writing at least 30 days before you intend to start leave (or as soon as practicable if the leave is unexpected). Include your expected start and end dates.
- Complete the employer’s leave request form. This typically asks for basic personal information, the reason for leave, and the anticipated duration.
- Provide medical certification. Your OB‑GYN must complete a certification form stating the expected delivery date and any medical complications that justify a longer leave.
- Submit a PFML claim through the Illinois Department of Insurance portal. You’ll need pay stubs, your most recent W‑2, and the employer‑completed PFML application.
- Optional: Apply for short‑term disability if your employer offers it. This usually requires a separate medical certification and may provide additional wage replacement.
- Maintain communication with your HR department throughout the process, confirming receipt of documents and asking about any additional forms.
Typical documentation checklist
- Employer’s leave request form (signed).
- Medical certification from your health care provider.
- Recent pay stubs and W‑2 (for PFML).
- Proof of address (if required for PFML).
- Any employer‑specific forms for short‑term disability or PTO.
Remember, the law requires your employer to keep all medical information confidential and to respond to your request within five business days.
Illinois employer obligations for maternity leave accommodations
Employers must balance business needs with legal responsibilities. In Illinois, the obligations fall into three categories: job protection, reasonable accommodations, and benefit administration.
Job protection
Under both FMLA and IFLA, an employee on eligible leave must be reinstated to the same or an equivalent position upon return. “Equivalent” means the same pay, benefits, and working conditions. Employers cannot use a pregnancy as a reason to demote, terminate, or otherwise discriminate.
Reasonable accommodations
If a pregnant employee needs adjustments—such as a temporary transfer to a lighter‑duty role, more frequent breaks, or a modified work schedule—Illinois law (mirroring the Pregnancy Discrimination Act) requires the employer to provide those accommodations unless it would cause undue hardship.
Benefits administration
Employers must continue health insurance coverage during leave on the same terms as if the employee were actively working, per the Consolidated Omnibus Budget Reconciliation Act (COBRA) and the Affordable Care Act (ACA). They also must accurately calculate and remit PFML contributions and, if applicable, short‑term disability premiums.
Difference between state and federal maternity leave laws in Illinois
Understanding the overlap—and the gaps—between state and federal law helps you make the most of the benefits available. The table below outlines the primary distinctions.
Key takeaways from the table
- Both FMLA and IFLA provide the same 12‑week unpaid protection; the main difference is employer size and state‑specific definitions.
- PFML is the only paid component, and it can be used concurrently with FMLA/IFLA, meaning you can receive wage replacement while still enjoying job protection.
- Eligibility for PFML is broader, so even if you don’t meet FMLA/IFLA thresholds, you may still receive paid benefits.
What is the job protection duration for maternity leave in Illinois?
Job protection lasts for the full length of your statutory leave—up to 12 weeks—provided you meet eligibility and follow the proper notice procedures. After those 12 weeks, you have a few options:
- Return to the same position if it remains available.
- Transition to a comparable position if your original role has been eliminated for legitimate business reasons (e.g., a department restructure).
- Negotiate an extension under the ADA or through an employer‑specific policy, which may involve a brief unpaid extension or a reduced‑hours arrangement.
If your employer fails to reinstate you, you may have a claim under both state and federal law. The U.S. Department of Labor’s Wage and Hour Division can investigate, and you may also pursue a civil action for wrongful termination.
Additional considerations: adoption, short‑term disability, part‑time workers, and extending leave
While pregnancy is the most common reason for maternity leave, Illinois law also protects adoptive parents, foster‑care placements, and those who need additional time due to medical complications.
Illinois maternity leave vs. California paid family leave
California’s Paid Family Leave (PFL) has been in place since 2004 and offers up to 8 weeks of paid benefits at about 60‑70 % of wages, with a higher maximum weekly benefit than Illinois. Illinois, however, provides a longer paid duration (12 weeks) and a higher wage cap. Both states require employer contributions, but California’s program is funded through employee payroll deductions, while Illinois’s is employer‑funded.
Can I take maternity leave while on short‑term disability in Illinois?
Yes. Short‑term disability (STD) is a separate benefit that covers a portion of your salary if you’re unable to work due to pregnancy complications (e.g., severe morning sickness, pre‑eclampsia). You can receive STD payments concurrently with PFML, effectively increasing your wage replacement. However, STD benefits are typically limited to a maximum of 6 weeks, after which you would rely on PFML for continued support.
Does Illinois maternity leave cover adoption?
Both FMLA and IFLA treat adoption and foster‑care placements the same as birth‑related leave. You’re entitled to up to 12 weeks of unpaid, job‑protected leave for bonding with an adopted child, and you can also receive PFML wage replacement during that period.
How does maternity leave affect unemployment benefits in Illinois?
Unemployment insurance (UI) is generally not payable while you’re on approved maternity leave, because you’re considered “temporarily absent” rather than “unemployed.” If you exhaust your statutory leave and are still unable to work, you may be eligible for UI, but you would need to meet the standard eligibility criteria (e.g., sufficient earnings, actively seeking work).
What is the maximum wage replacement rate for Illinois paid family leave?
In 2026, the maximum weekly benefit is $1,300, which translates to roughly 70 % of the average weekly wage in the state. For most middle‑income earners, this means a benefit of $900‑$1,200 per week, depending on exact earnings.
Illinois maternity leave policy for part‑time workers
Part‑time employees who meet the 1,250‑hour threshold are eligible for the same unpaid leave protections as full‑time staff. However, they may face challenges in qualifying for PFML if they earn below the state’s minimum wage threshold. Many employers address this gap by offering prorated PTO that can be used alongside PFML.
How to extend maternity leave beyond the statutory limit in Illinois
If you need more than 12 weeks, consider these options:
- Employer‑paid extended leave: Some companies have policies that grant up to 18 weeks of paid parental leave.
- ADA accommodation: If a pregnancy‑related condition qualifies as a disability, you can request a reasonable accommodation that may include additional leave.
- Unpaid leave agreement: Negotiate a voluntary, unpaid extension with your employer. While not guaranteed, many employers are willing to accommodate to retain talent.
Tax implications of maternity leave in Illinois
While PFML benefits are generally not taxable at the federal level, Illinois follows the same rule—paid family leave benefits are excluded from state taxable income. However, if you receive a combination of PFML, short‑term disability, and employer‑paid PTO, the portion that comes from a traditional employer‑paid salary (e.g., PTO) may be subject to regular income tax withholding. It’s a good idea to review your pay stub and discuss any concerns with your payroll department or a tax professional.
Additionally, if you are self‑employed or work as an independent contractor, you are not automatically covered by PFML. Some self‑employed individuals opt into a voluntary paid family leave program administered by the Illinois Department of Insurance, which requires separate contributions and provides similar tax‑free benefits.
Maternity leave and health insurance continuity
Maintaining health insurance during leave is critical, especially for prenatal care, postpartum check‑ups, and newborn vaccinations. Under the Consolidated Omnibus Budget Reconciliation Act (COBRA) and the Affordable Care Act (ACA), your employer must continue providing health coverage on the same terms as if you were actively working, for the duration of your FMLA/IFLA leave.
If you have a short‑term disability plan that pays a portion of your salary, the plan may also cover the employee premium portion of your health insurance. Always verify with your HR department how premiums will be handled during leave to avoid a lapse in coverage.
Myth vs. fact
Myth: Illinois does not have any paid maternity leave, so I’ll receive no money while I’m off.
Fact: Illinois’ Paid Family Leave program provides up to 12 weeks of wage replacement for bonding with a newborn, adoption, or foster placement. The benefit is typically 60‑70 % of your average weekly earnings, capped at $1,300 per week (2026).
Myth: Only full‑time employees can take maternity leave.
Fact: Part‑time workers who have logged at least 1,250 hours in the past year qualify for the same unpaid leave protections under FMLA and IFLA, and many can also access PFML regardless of hours worked.
Myth: If my employer is small, I’m not protected.
Fact: While FMLA applies only to employers with 50 + employees, the Illinois Family Leave Act covers employers with as few as 20 employees within a 75‑mile radius. Additionally, PFML covers workers at any size employer, because it is state‑funded.

Frequently asked questions
What is the length of maternity leave allowed in Illinois?
Both the federal FMLA and the Illinois Family Leave Act offer up to 12 weeks of unpaid, job‑protected leave per 12‑month period. Illinois’ Paid Family Leave can provide wage replacement for the same 12‑week duration.
Are Illinois maternity leaves paid or unpaid?
The statutory leave under FMLA and IFLA is unpaid. However, the state’s Paid Family Leave program can replace a portion of your wages for up to 12 weeks, and many employers also offer short‑term disability or paid time off that can be layered on top.
Do I qualify for maternity leave under the Illinois Family Leave Act?
To qualify, you must have worked for a covered employer (20 + employees within 75 mi) for at least 12 months and logged at least 1,250 hours in the preceding year. If you meet these criteria, you’re eligible for up to 12 weeks of unpaid leave.
Can an employer deny maternity leave in Illinois?
Employers cannot lawfully deny leave if you meet the eligibility requirements under FMLA, IFLA, or PFML. Any denial could constitute a violation of federal or state law, and you may file a complaint with the U.S. Department of Labor or the Illinois Department of Labor.
How does the federal FMLA interact with Illinois maternity leave laws?
The two systems run concurrently. If you qualify for both, you receive a single 12‑week block of leave that is both job‑protected and eligible for wage replacement through PFML. Your employer must count the leave once, not twice.
What documentation is required to take maternity leave in Illinois?
You’ll need a written notice to your employer (30 days in advance if possible), a completed employer leave request form, a medical certification from your health‑care provider confirming pregnancy and expected delivery date, and the PFML claim form with pay stubs and a recent W‑2. If you’re using short‑term disability, additional medical forms may be required.
Can I use PFML for adoption or foster‑care placement?
Yes. PFML covers bonding with an adopted child or a child placed in foster care, offering the same wage‑replacement benefits as for a birth‑related leave.
Can I use maternity leave for a C‑section recovery?
Absolutely. A C‑section is considered a serious health condition related to pregnancy, so it qualifies under both FMLA and IFLA. You can use the full 12 weeks for recovery, and PFML will provide wage replacement during that time.
What happens if I change jobs while on maternity leave?
If you switch employers during your leave, the new employer is not required to honor the leave you accrued with your former employer. However, you may be eligible for PFML benefits through the state program, as eligibility does not depend on employer size. You’ll need to re‑apply for PFML with your new employer’s information and may need to provide a new medical certification.
When to see a doctor or specialist
If you experience any of the following during pregnancy, contact your OB‑GYN immediately, as these issues may affect your leave eligibility or require additional medical documentation:
- Heavy bleeding or spotting.
- Severe abdominal pain or cramping.
- Sudden swelling of hands, face, or feet.
- Persistent high fever (above 100.4 °F/38 °C).
- Signs of pre‑eclampsia (e.g., headaches, vision changes, hypertension).
For legal or benefits questions, consider speaking with an employment attorney or a certified HR professional who specializes in family‑leave law. This article is for informational purposes only and does not replace personalized medical or legal advice.
