Deadlines, Limits and Plan Rules

Your FSA, HSA or HRA comes with rules about how much you can contribute, when you can use your money, and what happens to it at year's end. This section covers the deadlines that matter, the contribution limits your plan sets, and the account rules that shape how your benefits work.

Here you'll find answers to the questions that come up most often: How much can I contribute? When's the deadline to use my money, and is there a grace period? Can I carry unused funds over to the next year? Can I get a refund instead? When can I make changes to my account? And what's catch-up contribution, and am I eligible?

A letter of medical necessity doesn't change these rules. Your contribution limits, plan deadlines and carryover policies are set by your employer's plan and handled by your administrator. Once you have an eligible expense and a letter, Burst files the reimbursement claim on your behalf.
