The rules are different for medical and dependent-care flexible spending accounts. Here's what you need to know. By Kimberly Lankford, Contributing Editor November 13, 2012 I understand that the contribution limit for a medical flexible-spending account will drop to $2,500 in 2013. Is that the limit per household or for each working spouse? Our family’s out-of-pocket medical expenses average about $4,000 a year. Can I contribute $2,500 to my FSA at work and my wife $1,500 through her employer? Can I use money from my FSA for some of her expenses? And is the $5,000 limit for dependent-care FSAs per person or per family?The $2,500 limit for medical flexible-spending accounts is per person per plan rather than per household, so if you and your wife both have FSAs through your jobs, you can each contribute up to $2,500 in pretax money to your FSA accounts. You can use the money from either spouse’s FSA on out-of-pocket medical expenses (but not premiums) for any family member, including eligible dependents. Most plans even let you use medical FSA money for medical expenses for children through the year they turn age 26, whether or not they are covered under your health insurance or considered to be dependents for tax purposes. Check with your plan to see if it allows you to do so, says Jody Dietel, chief compliance officer for WageWorks, which administers FSA plans. The contribution rules are different for dependent-care FSAs. That $5,000 limit applies per family if you are married filing jointly or if you are a single parent (or $2,500 each if you are married filing separately). So if both you and your wife are offered dependent-care FSAs at work, be careful not to exceed the limit when you sign up during open-enrollment period.
