My insurance let me make changes to my DCFSA mid-year, if there was a change in the price of daycare, which included changes due to tax changes. So, I'm planning on not contributing to the DCFSA next year until we know if/what the changes will be.
2020 - DCFSA was the best for us
2021 - DCFSA was the best, until the child care tax credit increased to 50%
2022 - Will BBB cap child care expenses at 7% of AGI, or will the increased child care tax credit be extended, or nothing? We'll see. I'm planning on not contributing to the DCFSA for at least the first part of the year.
