HSA Details:
The maximum HSA contribution for 2023 is $3,850 for self-only and $7,750 for families. Your HSA contributions can be invested and the gains on invested funds are tax free.
There is no limit to the amount you can withdraw within one year from your HSA as long as the funds were spent on qualified medical expenses. With proper documentation, you can take a reimbursement for all qualified expenses since you initially opened your HSA account.
For example, if you opened your HSA in 2018, you can use HSAMax to identify all the qualified medical expenses you've purchased from retailers over the last 5 years and take a deduction for all those purchases.
FSA Details:
The maximum FSA contribution for 2023 is $3,050 that comes as a salary deferral contribution for an individual employee.
FSA funds that are not spent within the plan year can include a two-and-a-half-month grace period to spend down remaining FSA funds, if employees are enrolled in FSAs that have adopted the grace period option.
Health FSAs have an additional option of allowing participants to carry over up to $610 of unused funds at the end of the plan year, and still contribute up to the maximum in the next plan year. Health FSA plans can elect either the carryover or grace period option but not both.
