Irmaa Brackets 2025 Chart. In 2025, the medicare irmaa brackets will be adjusted based on the income you reported two years prior, which means your 2023 income will determine your irmaa for 2025. It’s structured in brackets, so every higher income tier corresponds to a higher irmaa charge.
The 2025 irmaa brackets are expected to affect even more retirees than the current brackets. In 2025, with the inflation adjustment to the irmaa brackets, you will no longer have a part d or part b irmaa payment.
