Does the Order Date or Delivery Date Count for Your FSA? A Year-End Guide

Short answer: for an FSA, what usually counts is whether the expense falls inside your plan year (or grace period) — and plans differ on whether that means the order date or the delivery date, so if you're buying near December 31, order early and ask your administrator how they treat it.

If you've got money left in a health FSA and the calendar is running down, this is the question that keeps people up at night: does it count if I buy it on December 28th and it shows up in January? Let's walk through it in plain English.

What does "incurred" mean for an FSA?

"Incurred" is the word FSAs use for the date an expense counts. A health FSA reimburses eligible expenses incurred during your plan year (plus a grace period, if your plan has one), not just any money you spent that year. Your plan administrator and your employer's plan document decide the details, which is why two people with different plans can get different answers.

For a doctor's visit, the date of service is the obvious marker. For a physical product like a red light therapy device, administrators generally look at the purchase or delivery date, and policies vary. That's the part worth confirming before the last week of the year.

Does the order date or the delivery date count?

It depends on your plan, so ask. Many administrators accept an itemized receipt dated within the plan year for in-stock goods. Others pay closer attention to when the item was actually delivered or placed in service. Neither is "wrong"; it's a plan-design choice.

The safest move is a short call or message to your administrator: "If I order an eligible device on December 20 and it arrives January 3, which plan year does it fall in?" Get the answer in writing if you can. And if you'd rather not gamble, order a couple of weeks early so both dates land inside the year.

How much time should you leave before the deadline?

More than you think. Holiday shipping slows down, and a plan year that ends December 31 gives you very little cushion if your device ships late. Aim to order by early-to-mid December. If your plan has a grace period or a carryover instead, you have more room, but remember a plan generally offers one or the other, not both. Our guide to FSA rollover vs. grace period explains how to tell which you have.

Does an HSA work the same way?

No, and that's good news. An HSA doesn't have a use-it-or-lose-it deadline; the balance is yours and rolls over. You can also generally reimburse yourself later for qualified expenses, as long as the expense happened after your HSA was opened and you keep the receipt. So the year-end scramble is mostly an FSA problem. If you have both accounts, see how they fit together in our post on having an FSA and an HSA at the same time.

What should you keep so the claim goes through?

Hold on to an itemized receipt showing the date, the item and the amount, plus the shipping confirmation and delivery date. If your administrator asks for substantiation after the fact, those documents answer nearly every question. Our post on FSA receipt requests covers what to send. For the full how-to on paying with pre-tax dollars, start with our FSA/HSA guide for red light therapy.

Which device makes sense if you're short on time?

If you want a targeted panel, the FX300 ($199.99) is our compact option. For back, knee, waist or shoulder discomfort, the Red Light Therapy Belt ($119.99) is a lower-cost choice. Not sure? The device finder quiz takes about a minute. Red light therapy is studied as a wellness add-on, not a cure, so pick the one you'll actually use consistently.

Frequently asked questions

Can I buy something on December 31 with my FSA?

Often yes, if the purchase and the receipt are dated within your plan year, but confirm whether your plan also looks at the delivery date.

What if my device arrives after the plan year ends?

That depends on your administrator's policy. Some will honor a purchase made in the plan year; others may not. Ask before you order.

Does the grace period change this?

If your plan has a grace period, expenses incurred during it can generally be paid from the prior year's balance. It's the plan's choice whether to offer one.

Do HSA funds expire at year-end?

No. HSA balances roll over, so there is no year-end deadline to race.

Can I use FSA money on something ordered but not yet shipped?

Plans differ. Many reimburse against an itemized receipt; some want proof of delivery. A quick call settles it.

The bottom line

Don't leave an FSA balance to chance in the last week of December. Ask your administrator how they treat order and delivery dates, order early, and keep your paperwork. Sources worth bookmarking: the IRS's Publication 969 on health FSAs and its section on flexible spending arrangements.
