Thanks for your question.
IRS regulations state that flexible spending account (FSA Sec 125) plans must state a medical FSA maximum with the amount determined by the plan. Therefore, you will need to check with your employer as the FSA plan document will explicitly state this limit. The IRS does not set this medical FSA limit.
Dependent care FSA maximum is determined by IRS regulations. This is $5000 per family, or $2,500 each if married filing seperate returns.
Hope this helps,
