While the American Rescue Plan initially set this lower threshold for 2022 and beyond, the IRS delayed implementation, keeping the old rule ($20,000 and 200+ transactions) for 2022 and 2023, then phasing in a $5,000 threshold for 2024, before recent legislation reverted the federal threshold back to the old $20,000 and 200+ transactions for 2023 and future years (as of late 2025/early 2026), aiming to reduce confusion.
