Citi Benefits Handbook
Marital Status and Your DCSA Contribution
If you file a joint tax return: You and your spouse together may contribute up to $5,000 a year before taxes to the DCSAs. For example, if your spouse contributes $2,000 to his or her employer's DCSA, you can contribute up to $3,000 to your DCSA. If either you or your spouse earns less than $5,000 annually, the combined amount you and your spouse contribute cannot exceed the lower salary.
If you file separate tax returns: You and your spouse each may contribute up to $2,500 a year before taxes to your respective DCSA.
If your spouse does not work: In general, you cannot use the DCSA if your spouse does not work, unless he or she is a full-time student for at least five months during the calendar year, is looking for work, or is disabled. In such a case, for purposes of determining the maximum contribution, your spouse is considered to earn $250 a month if you have one qualified dependent or $500 a month if you have two or more qualified dependents. For Plan purposes, count only the months that your spouse is either in school or disabled.
These limits are subject to change.
