The applicable dollar amount under section 219(g)(3)(B)(ii) for all other taxpayers who are active participants (other than married taxpayers filing separate returns) is increased from $73,000 to $77,000. If an individual or the individual’s spouse is an active participant, the applicable dollar amount under section 219(g)(3)(B)(iii) for a married individual filing a separate return is not subject to an annual cost-of-living adjustment and remains $0.

For a married individual filing a separate return who is an active participant, the phase-out range is not subject to an annual cost-of-living adjustment and remains $0 to $10,000.
