Dependent Care FSA Limit Calculator
A dependent care flexible spending account (FSA) lets you set aside pre-tax money for work-related child or dependent care. The annual exclusion is capped at $5,000 (or $2,500 if married filing separately), and it cannot exceed your earned income or, if married, your spouse's earned income. This calculator takes the smallest of your intended contribution, the statutory limit, and the relevant earned-income figures to find your maximum excludable amount, then estimates the federal tax it saves at your marginal rate.
Dependent care FSA formula
Excludable = min(contribution, statutory limit, your earned income, spouse earned income)
Estimated tax savings = excludable * (marginal rate / 100)
Contribution over the limit = max(0, contribution - excludable)
Excludable per month = excludable / 12
If you are not married, use your own earned income for the spouse field set high enough not to bind, or enter your own income twice. The exclusion is the smallest of all applicable limits.
Dependent care FSA context
- The statutory exclusion is $5,000, or $2,500 if married filing separately, under IRC Section 129.
- The exclusion cannot exceed your earned income or your spouse's earned income.
- Contributions avoid federal income tax and FICA (Social Security and Medicare) taxes.
- You cannot use the same expenses for both the FSA and the Child and Dependent Care Credit.
- Qualifying care must enable you and your spouse to work or look for work.
Dependent care FSA: frequently asked questions
What is the dependent care FSA contribution limit?
The annual exclusion limit for a dependent care flexible spending account is $5,000 for most filers and $2,500 if married filing separately, as set in Internal Revenue Code Section 129. The excludable amount is also limited to your earned income and, if married, your spouse's earned income. This calculator applies the lowest of these limits.
How does the earned-income limit work?
Your excludable dependent care benefit cannot exceed your own earned income, and if you are married, it also cannot exceed your spouse's earned income. So a married couple where one spouse earns only $3,000 can exclude at most $3,000, even though the statutory limit is $5,000. This calculator takes the smallest applicable figure.
How much tax does a dependent care FSA save?
Contributions are excluded from federal income tax and from Social Security and Medicare (FICA) taxes. Your savings equal the excludable amount multiplied by your combined marginal rate. This calculator multiplies the excludable amount by the marginal tax rate you enter to estimate the savings.
Can I use both the FSA and the dependent care tax credit?
You cannot use the same expenses for both. Amounts excluded through a dependent care FSA reduce the expenses eligible for the Child and Dependent Care Credit. Many families use the FSA up to its limit and then claim the credit on any remaining eligible expenses, subject to the credit's own dollar limits.
What expenses qualify?
Qualifying expenses are work-related care costs for a child under 13 or a dependent unable to care for themselves, such as daycare, before- and after-school care, or a day camp. The care must let you (and your spouse, if married) work or look for work. Overnight camp and schooling at the kindergarten level or above do not qualify.
