The good news is that none of the changes to the Affordable Care Act, Medicaid, or other health-insurance-related tax items in the One Big Beautiful Bill Act (OB3A) were retroactive to the beginning of 2025. The bad news is that the first set of changes is coming in 2026. The worse news is that some changes that were not included in the final version of OB3A are included in a new Federal Rule – but the provisions of the Federal Rule are only temporary. Basically, what we have is some federal rulemaking that was designed to give Congress time to codify the rule’s provisions into law, but only some of the provisions were codified – which simply means the provisions are merely temporary, not invalid. This article is going to discuss some of the important provisions concerning healthcare coverage that are included in OB3A, one that didn’t make it into the law, but that is in the new Federal Rule, and two that kind of blew up on social media but aren’t in OB3A or in the new rule.

2026 Changes to Form 2441 and Dependent Care Benefits
The credit for dependent-care expenses (such as daycare costs) has long been stuck at 20% for “average” taxpayers. It finally gets a permanent boost in 2026 (for returns filed in 2027). Also, the amount of money a taxpayer can put into a dependent care assistance program is increasing by $2,500 for 2026. This change presents a chance for taxpayers and tax pros to reevaluate which is better – claiming the credit or using a flex plan.
