A second requirement is that all applications for refunds must be made by a date defined by the plan. If funds are forfeited, this does not eliminate the requirement to pay taxes on these funds if such taxes are required. For example, if a single person elects to withhold $5,000 for child care expenses and marries a non-working spouse, the $5,000 would become taxable. If this person did not submit claims by the required date, the $5,000 would be forfeited but taxes would still be owed on the amount.
