Key FMLA Deadlines Employers Should Track
These are the major employer response deadlines that should be built into your leave administration workflow.
Eligibility Notice Deadline
When an employee requests leave or the employer learns leave may be for an FMLA-qualifying reason, the employer must provide eligibility notice within five business days.
- Triggered by a possible FMLA reason
- Communicates whether employee appears eligible
- Should document reason if employee is not eligible
- Usually paired with Rights & Responsibilities
Rights & Responsibilities Deadline
Each time the employer is required to provide the Eligibility Notice, the employer must also provide the employee with the Rights & Responsibilities Notice.
- Must be in writing
- Explains certification expectations
- Explains benefit premium obligations
- Explains consequences of missed obligations
Medical Certification Deadline
When certification is requested, employees generally must be given at least 15 calendar days to provide complete and sufficient certification.
- Use when certification is needed
- Generally 15 calendar days
- Good-faith delays may require more time
- Track request date and due date
Incomplete or Insufficient Certification
If certification is incomplete or insufficient, employers should identify what information is needed and provide the employee an opportunity to correct it.
- State what is missing or unclear
- Provide written follow-up
- Generally allow 7 calendar days to cure
- Document all communication
Designation Notice Deadline
Once the employer has enough information to determine whether leave qualifies as FMLA leave, the Designation Notice is generally due within five business days.
- Confirms whether leave is FMLA-protected
- States amount counted when known
- May identify incomplete or insufficient certification
- Should be kept in the leave file
Fitness-for-Duty Timing
If a fitness-for-duty certification will be required before return to work, the employer should communicate that requirement in the Designation Notice.
- Use only when policy or practice supports it
- Must relate to the FMLA condition
- Essential job functions should be addressed when required
- Coordinate with ADA when restrictions exist
FLARE™ Insight
One missed FMLA deadline may be a mistake. Repeated missed deadlines usually indicate a broken leave administration process. Strong leave administration is not about remembering every deadline manually. It is about building a workflow where intake, notices, certification, designation, benefits, payroll, and return-to-work steps are tracked automatically.

Common FMLA Deadline Mistakes
These are the timing problems employers should audit in their leave administration process.
Starting the Clock Too Late
Employers sometimes wait for a formal FMLA request even when they already have enough information to know leave may qualify.
Missing the 5-Day Notice Window
Late eligibility or designation notices can create confusion about employee obligations and leave tracking.
No Certification Due Date
If the certification request does not include a clear due date, follow-up becomes harder to administer.
Not Explaining What Is Missing
If certification is incomplete or insufficient, employees need a written explanation of what must be corrected.
Never Sending WH-382
Employers should document whether leave is approved, denied, or pending additional information.
No Central Deadline Tracker
FMLA deadlines should not depend on memory, email threads, or manager follow-up alone.
