You may be in luck. Due to COVID-19 many people are having problems estimating their dependent care FSA amounts. Some people have needed more care, while others have needed less. One of the changes covered in the CARES act is related to Health Savins account, and Flexible spending accounts.
This is from the IRS: COVID-19 GUIDANCE UNDER § 125 CAFETERIA PLANS AND RELATED TO HIGH DEDUCTIBLE HEALTH PLANS Notice 2020-29
I put the key parts in bold.
To assist with the nation’s response to the 2019 Novel Coronavirus
outbreak (COVID-19), this notice provides for increased flexibility
with respect to mid-year elections under a § 125 cafeteria plan during
calendar year 2020 related to employer-sponsored health coverage,
health Flexible Spending Arrangements (health FSAs), and dependent
care assistance programs.
This notice provides temporary flexibility for § 125 cafeteria plans
to permit employees to make certain prospective mid-year election
changes for employer-sponsored health coverage, health FSAs, and
dependent care assistance programs during calendar year 2020 that the
plan chooses to permit. Specifically, an employer, in its discretion,
may amend one or more of its § 125 cafeteria plans (including limiting
the period during which election changes may be made) to allow each
employee who is eligible to make salary reduction contributions under
the plan to make prospective election changes (including an initial
election) during calendar year 2020 regarding employer-sponsored
health coverage, a health FSA, or a dependent care assistance program,
regardless of whether the basis for the election change satisfies the
criteria set forth in Treas. Reg. § 1.125-4. In particular, an
employer may amend one or more of its § 125 cafeteria plans to allow
employees to: (1) make a new election for employer-sponsored health
coverage on a prospective basis, if the employee initially declined to
elect employer-sponsored health coverage; (2) revoke an existing
election for employer-sponsored health coverage and make a new
election to enroll in different health coverage sponsored by the same
employer on a prospective basis (including changing enrollment from
self-only coverage to family coverage); (3) revoke an existing
election for employer-sponsored health coverage on a prospective
basis, provided that the employee attests in writing that the employee
is enrolled, or immediately will enroll, in other health coverage not
sponsored by the employer; (4) revoke an election, make a new
election, or decrease or increase an existing election regarding a
health FSA on a prospective basis; and (5) revoke an election, make a
new election, or decrease or increase an existing election regarding a
dependent care assistance program on a prospective basis.
My reading is that this is optional, but the IRS will allow it this year. Talk to HR, show them the information from the IRS. Talk to the company that is administrating the plan. I have found similar information on several administrator web sites.
