Do I Really Need My Babysitter's Social Security Number Just to Get FSA Reimbursement?
Filing a dependent care FSA claim for the first time is often the moment a parent realizes the paperwork wants more than just a receipt — it wants a name, an address, and a taxpayer identification number for whoever provided the care. If that caregiver is a neighborhood teenager or a family friend rather than a licensed daycare, this can turn into an awkward conversation nobody planned for.
In a nutshell
Yes, dependent care FSA reimbursement generally requires identifying information for the care provider, including either a Social Security number or an employer identification number, because the plan has to substantiate the claim. This is a standard requirement built into how these accounts work, not something a particular plan administrator invented, though the exact paperwork can vary slightly by plan.
Why the form asks for this in the first place
A dependent care FSA lets a portion of pay go toward care costs before certain taxes are applied, and the tradeoff for that treatment is documentation. The provider’s identifying number is part of what allows the reimbursement to be substantiated as a legitimate care expense rather than an unverifiable claim. It also mirrors what shows up on the related tax form used to claim a dependent care credit, which similarly asks for provider information. This is part of a broader pattern where claims and deductions tied to taxes tend to require more documentation than people initially expect, even for relatively small, informal arrangements.
Why this creates friction with informal caregivers
A babysitter who’s a teenager earning cash on the side, or a retired neighbor helping out occasionally, often isn’t thinking of the arrangement as a formal employment relationship, and providing a Social Security number for someone else’s benefits paperwork can feel like an odd ask. There’s also a reasonable question on the caregiver’s side about what this means for their own taxes, since income earned from informal work like babysitting is generally still taxable whether or not a formal form ever gets filed. Some caregivers are simply unfamiliar with why a parent would need this information at all, which is worth explaining plainly rather than assuming it’s understood.
What people discuss doing about it
- Raising it before the arrangement starts, not after. Bringing up the reimbursement paperwork at the time care is arranged, rather than after several months of babysitting, tends to avoid an awkward retroactive request.
- Explaining why it’s needed. A short, honest explanation of what the FSA requires can go a long way toward easing a caregiver’s hesitation, since the request can otherwise feel arbitrary or intrusive.
- Considering whether the arrangement fits FSA rules at all. Not every informal care setup qualifies, and some families decide the reimbursement isn’t worth the friction and choose not to submit a claim for that portion of care.
- Keeping personal records either way. Dates, amounts paid, and the reason for care are worth documenting for as long as tax records are generally recommended to be kept, regardless of whether an FSA claim is ultimately filed.
The takeaway
The paperwork isn’t arbitrary, but it does collide with how a lot of informal child care actually happens, which is why this question comes up so often. Being upfront with a caregiver about what the reimbursement process requires, and giving them the chance to decide whether they’re comfortable providing that information, tends to go over better than requesting it as an afterthought once a claim is already being filed.
