Stacked, supplemental, or offset: the three ways your employer's leave policy interacts with state PFML
By Christine · Published July 6, 2026
If your employer offers paid parental leave, it's coordinating with your state's PFML program in one of three ways. The difference between them, on a 12-week leave, is often $10,000 to $20,000 of household income.
Most parents assume the two benefits stack. Most of the time they don't. Here are the three patterns, what to look for, and the exact question to ask HR in writing before you file.

Pattern 1: Stacked
Stacked means your employer pays their policy IN ADDITION to whatever the state pays. Best case for you.
If your state PFML pays $1,016.40/week and your employer's policy pays 100% of your $1,500/week wage, a stacked structure means:
- State PFML: $1,016.40/week
- Employer policy: $1,500/week
- Total: $2,481/week
Obviously that's more than your normal paycheck, which is why very few employer policies are truly stacked. Some are, though. Some tech companies, some union contracts, some state and federal employers. If you have this, ask HR to confirm it in writing before you assume, because "stacked" gets misused casually.
Pattern 2: Supplemental (also called "top-up")
Supplemental means your employer pays the difference between state PFML and a target percentage of your wages. Common in generous private-sector policies.
Say your state PFML pays $1,016.40/week and your employer's policy tops you up to 100% of a $1,500/week wage. The math:
- State PFML: $1,016.40/week
- Employer top-up: $483.60/week (the gap between $1,016.40 and $1,500)
- Total: $1,500/week
That's your normal paycheck. Employer's cost is only the top-up portion, which is why supplemental is the most common pattern in modern policies.
If HR describes their policy as "we pay 100% of your wages during leave," ask specifically whether it stacks on top of state PFML or supplements state PFML. In most cases it's supplemental.
Pattern 3: Offset
Offset means the employer pays their policy MINUS what state PFML pays. Worst case for you.
Say your employer's policy says "we pay 100% of your wages for 12 weeks." Offset means:
- State PFML: $1,016.40/week
- Employer policy: $1,500 - $1,016.40 = $483.60/week
- Total: $1,500/week
You get the same net amount as supplemental, but here's the catch: if you don't file the state PFML claim, your employer's offset payment doesn't automatically increase. You just get $483.60/week and lose the $1,016.40 you should have received from the state.
Offset is designed to reduce the employer's cost. If you file state PFML correctly, the total is the same as supplemental. If you don't, you take a $1,016.40/week haircut.
The 12-week math on all three patterns
For a birthing parent earning $1,500/week in Connecticut ($1,016.40 state PFML cap) with a 12-week leave and a 100%-of-wages employer policy:
- Stacked: State $12,197 + Employer $18,000 = $30,197 total
- Supplemental: State $12,197 + Employer top-up $5,803 = $18,000 total
- Offset: State $12,197 + Employer difference $5,803 = $18,000 total (if state filed) OR $5,803 total (if state not filed)
The gap between best case (stacked, $30,197) and worst case (offset with unfiled state, $5,803) is $24,394 for a single 12-week leave.
Most parents don't know which pattern applies to them until they file, and by then it's often too late to correct.
The one question to ask HR in writing
Send an email. Not a phone call. Email creates a written record you can reference later.
Subject: Coordination of company parental leave policy with state Paid Family and Medical Leave
Hi [HR contact],
I'm planning my parental leave for [expected event date] and want to confirm how our company's paid parental leave policy coordinates with our state's Paid Family and Medical Leave program.
Specifically, please confirm which of the following applies:
- Stacked. Our company policy pays IN ADDITION to state PFML. Both amounts are received.
- Supplemental. Our company policy TOPS UP state PFML to a target percentage of my wages.
- Offset. Our company policy pays the policy amount MINUS what state PFML pays.
If it's #2 or #3, please also confirm whether I need to file the state PFML claim myself (I believe I do), and what happens to the employer payment if I don't file the state claim.
Thanks for putting this in writing so I can plan accordingly.

If HR can't answer in writing within a reasonable window, escalate. This is worth thousands of dollars.
The pattern most large employers use in PFML states
Most large private employers in states with PFML programs default to supplemental or offset because it's cheaper for them. HR handbooks often describe the benefit vaguely ("we pay full salary during leave") without specifying which coordination pattern applies. That vagueness is where the money leaks.
Employers with unionized workforces sometimes have contract-negotiated stacked benefits. State and federal government employees often have supplemental. Startup and small-employer policies are all over the map.
