If Divorced Parents Split Tuition, Do You Give Each One a W-10?

It's the second week of January, and you have two text messages sitting in your phone from the same enrolled family — except it's not really one family anymore. Mom asks for "the daycare's tax ID for my accountant." A few hours later, dad asks for the exact same thing, for his. They've split tuition all year under a signed 50/50 arrangement, each paid their half on time, and now each one needs your provider information for their own return.

Your first instinct might be that you can only give this to one of them — the "real" one, whoever that is. You don't have to figure that out. Tax season surfaces a cluster of once-a-year questions like this one — what a W-10 even is, whether a CDA credential you paid for this year is deductible, whether a parent's FSA paperwork means anything new for you — and this is one of the more common ones once a family splits into two households.

Yes, you can give a W-10 to both parents

Nothing in Form W-10 or its instructions limits you to handing your information to a single person per child. The form exists so a person who paid for care can document who they paid, as backup for their own return. If both parents genuinely paid you — under whatever split arrangement you worked out, which we cover separately on the billing side — both of them are people who paid for care, and both are entitled to accurate information from you: your name, your address, and your taxpayer identification number.

Handing it over doesn't mean you're vouching for either parent's tax position. You're confirming a fact — that you provided care, and this is who you are, tax-ID-wise. If you've already gotten the free EIN this site recommends over handing out your SSN, this part is easy: it's the same number, every year, for every family, including both halves of a split one. Fill out your section, sign it, and hand a copy to whoever asks and actually paid you.

The separate — and bigger — question your W-10 doesn't settle

Here's where it gets more interesting than a simple copy-and-hand-over. Having your W-10 information doesn't mean a parent can actually use it to claim the Child and Dependent Care Credit. That's governed by a completely different rule, and it has nothing to do with who paid.

Per IRS Publication 503, when parents are divorced, legally separated, or living apart, generally only the custodial parent can treat a child as a "qualifying person" for the Child and Dependent Care Credit. The custodial parent is defined specifically: it's the parent the child lived with for the greater number of nights during the year. If the nights split exactly evenly, the custodial parent is whichever parent has the higher adjusted gross income. The IRS is explicit that the noncustodial parent can't treat the child as a qualifying person for this credit — even in situations where that same parent is allowed to claim the child as a dependent under the separate, special divorced-parents dependency rules. Dependency and the dependent care credit are decided by different tests, and they don't automatically travel together.

Notice what's not in that test: who actually wrote the checks to you. A parent can faithfully pay their full 50% share of tuition all year, ask you for a W-10, receive accurate information from you — and still not be able to use the credit, because the custody-nights math doesn't go their way. That's not a loophole or a mistake on your end. It's simply a different rule answering a different question. (There are narrow exceptions built into the custody rules themselves, which Publication 503 references — exactly the kind of fine print a parent's own tax preparer needs to check, not something to guess at from a blog post.)

This isn't yours to adjudicate

It's tempting, once you learn this, to feel like you need to figure out which parent "deserves" the W-10 and only give it to that one. Resist that. You don't have visibility into the custody schedule down to the night, you're not positioned to apply a tiebreaker on adjusted gross income, and it isn't your role to referee which parent's accountant gets to use your information. Your job stays simple and the same as it's always been: if someone paid you for care and asks for accurate provider identification, you give it to them, honestly, the same way every time.

Refusing a W-10 to a parent who did pay you — because you suspect, correctly or not, that they're the noncustodial one — creates a different problem. Federal rules require a care provider to furnish a valid taxpayer ID to a person who paid for care, and that obligation isn't conditioned on whether you personally think their tax situation will work out. Give the information. Let the two households and their own tax preparers sort out who ultimately claims what.

The same logic extends to a dependent care FSA, if one parent's employer offers one. FSA reimbursement runs on a similar underlying "qualifying person" test to the credit — so a noncustodial parent whose employer offers an FSA can run into the identical wall even after you've given them everything they asked for. Again, not something you need to anticipate or manage. Give accurate information to whoever paid you and asks.

What actually helps here: knowing who paid what

The one thing worth doing on your end, if you haven't already, is keeping a record that shows each parent's own payments separately rather than one combined family total. If dad's accountant specifically wants to know how much dad personally paid you in a given year — as opposed to the household total — you want to be able to answer that in thirty seconds instead of reconstructing it from a notebook or a year of Venmo notifications. This is the same discipline the billing-split article recommends for the day-to-day invoicing side, and it pays off again here at tax time.

None of this is tax advice, and it shouldn't substitute for a parent's own CPA reviewing their specific custody and payment situation — this is general information, not tax advice, and the custodial-parent determination genuinely needs a professional who can see the full picture. Your role is narrower and more mechanical than it might feel in the moment: confirm your information is accurate, give it to anyone who paid you and asks, and let the two households handle the rest with their own professionals.

Where DaycareFlow fits

DaycareFlow doesn't generate W-10s, determine custodial-parent status, or file anything with the IRS — none of that is something software should be doing on your behalf. What it does keep is the record that makes a January request like this fast instead of stressful: per-child profiles that hold contact information for up to three parents, and a per-child billing record with the rate and frequency you agreed to, so if you need to confirm how much a specific parent paid over the year, you're reading it rather than guessing.

Frequently asked questions

Can I give a W-10 to both divorced parents if they both paid me?

Yes. Form W-10 isn't limited to one recipient per child — it's meant to document who paid for care and confirm your identifying information for their own records. If both parents genuinely paid you under your split arrangement, both are entitled to accurate information from you.

Who can actually claim the Child and Dependent Care Credit when parents are divorced?

Generally only the custodial parent — defined under IRS Publication 503 as the parent the child lived with for the greater number of nights during the year, with adjusted gross income as a tiebreaker for an exact split. This holds even if the other parent is allowed to claim the child as a dependent under separate rules, and it applies regardless of which parent actually paid you.

What if the parent who paid their share can't use the credit?

That can genuinely happen, and it isn't a problem you created or need to fix. A noncustodial parent can pay their full share of tuition all year and still not qualify to use the Child and Dependent Care Credit, because eligibility turns on custody nights, not payment. Their own tax preparer is the right person to help them figure out their options.

Do I need to decide which parent "deserves" the W-10?

No, and you shouldn't try. You don't have reliable visibility into the custody schedule or either parent's full tax picture, and it isn't your role to referee. Give accurate provider information to whoever paid you and asks for it, consistently, every time.

Should I keep separate payment records for each divorced parent?

Yes, if they're each paying their own share. A per-parent payment record, not just a combined household total, means you can answer a specific "how much did I personally pay you" question quickly — exactly the kind of thing a parent's accountant may ask for when sorting out their own eligibility.
