Dependent Care FSA Calculator: 2026 Household Split

Enter annual elections, employer funding and plan caps to coordinate two dependent-care accounts. Joint filers share one household ceiling; separate filers enter only their own benefits.

Inputs
Considered unmarried requires living apart from your spouse for the last 6 months, the qualifying person living in your home for more than half the year, and you paying more than half its upkeep. Select that option only if all conditions hold.
USD/year
Use earned income for dependent-care purposes, not household AGI.
USD/year
Include any deemed income you have separately established under IRS student/incapacity rules.
USD/year
Only care enabling work or a job search: a qualifying child under 13, or a spouse/dependent incapable of self-care who lives with you more than half the year (dependency exceptions may apply). Noncustodial parents cannot claim this care even if claiming the child as a dependent. Exclude payments to your spouse, the child’s parent, your dependent, or your child under 19 at year-end. Ordinary teenage care is outside scope. Do not double-count a spouse’s claim. See Publication 503.
Use only for equal actual earnings in each qualifying month. Enter actual annual income above, without deemed income. Only one spouse may use deemed income in any month; the other income entry must exclude deemed income for these months. For uneven earnings or alternating spouses, calculate monthly amounts separately with Publication 503 and leave this helper off.
USD/year
Example. Enter the combined employee + employer cap from this plan.
USD/year
Include all employer-paid dependent-care assistance.

Example. For joint filers B may be the spouse’s employer. Otherwise B is another employer of yours.

  • This is an election planning ceiling, not a calculation of taxable benefits or the dependent-care tax credit. Actual eligible expenses and plan testing can reduce the exclusion.
  • The allocation retains A first for convenience; it does not rank employers. Employer contributions are held fixed. Unallocated room may still be blocked by plan limits.

How it works

Publication 15-B sets the 2026 annual exclusion at $7,500, or $3,750 for married filing separately. Employer assistance and salary-reduction elections share that ceiling. Earned income and eligible expenses can lower it.

Supported ceiling = min(statutory cap, your earned income, spouse earned income for joint or ordinary separate filers, eligible expenses)

We subtract employer contributions, then retain the requested A election within its plan cap and the remaining ceiling. B receives the remaining room, up to its requested election and plan cap. This is one feasible allocation, not an optimal tax strategy. Plan-cap excess and household excess overlap; do not add them. No intermediate rounding; displayed dollars round to cents.

Separate filers considered unmarried use their own earned income for both income limits, retaining the $3,750 separate-filer cap. Under the Form 2441 instructions, they must live apart for the last 6 months, provide the qualifying person’s main home for more than half the year and pay more than half its upkeep.

Worked examples

Two plans, one ceiling

With $500 from employer A, employee elections of $4,500 at A and $2,500 at B total $7,500. If both incomes and care expenses exceed that amount and the plan caps are $5,000 and $7,500, no reduction is needed.

A lower-earning spouse

With the same elections but spouse earned income of $6,000, the supported ceiling is $6,000. Retain $4,500 at A and $1,000 at B; reduce employee elections by $1,500.

Frequently asked questions

Can each spouse elect $7,500?
Joint filers share the $7,500 exclusion in 2026. The calculator combines both spouses’ benefits.
What if my employer still limits the plan to $5,000?
Enter $5,000 as that plan’s total cap if it includes employer funding. Confirm the cap’s definition with benefits staff; the federal increase does not establish your employer’s election rules.
How do I handle a student or disabled spouse?
The optional helper applies the Publication 503 floor of $250 per qualifying month for one qualifying person, or $500 for two or more. It adds months × max(0, floor − actual monthly earnings) to actual annual income. Only use it when each qualifying month has equal earnings; otherwise establish income month by month separately. Full-time students must meet the five-calendar-month enrollment test. Only one spouse may use deemed income in the same month; confirm the other income entry has none for these months.
Does excess here mean taxable wages?
No. This compares planned funding with a supported exclusion ceiling. Actual reimbursements, forfeitures and plan testing determine tax reporting. It does not calculate the dependent-care tax credit.
Which care expenses qualify?
Under Publication 503, care must enable work or a job search. A qualifying child is generally under 13; a qualifying spouse or dependent incapable of self-care must live with you more than half the year, subject to dependency exceptions. A noncustodial parent cannot claim this care even when claiming the child as a dependent. Exclude providers who are your spouse, the child’s parent, your dependent, or your child under 19 at year-end. Ordinary teenage childcare is outside scope. Confirm eligibility beside the expense input before calculating.
