Here’s some unwelcome news: retirees with higher incomes who’ve been hit with premium surcharges for Medicare Part B and Part D may have another hit coming in 2018. That’s because the income thresholds for the highest surcharge tiers decrease next year, meaning a greater number of beneficiaries will be affected with higher premiums.
Kiplinger’s recent article, “Medicare Surcharge Thresholds to Drop,” reports that resetting the trigger points was part of the Medicare Access and CHIP Reauthorization Act of 2015 (called the "Doc Fix" Law). The legislation ended the yearly battles over fee schedules for doctors' Medicare payments. High-income beneficiaries were tapped to be on the hook to help pay for the permanent fix.
Next year there’ll still be four surcharge tiers, and no surcharge for beneficiaries whose modified adjusted gross income (AGI plus tax-exempt interest) is less than $85,000 for single filers or $170,000 for married taxpayers filing jointly.
However, the tops of the other tiers are narrowed to create an upward push for beneficiaries: some income levels that have been in Tier Two will then be jumped up to Tier Three. Some beneficiaries previously in Tier Three, will be bumped up to the most expensive level, Tier Four.
Previously, the highest surcharges were triggered when an individual’s MAGI passed $214,000 or $428,000 for married couples. Those trigger points drop 25% in 2018 to $160,000 and $320,000 respectively.
Your 2016 tax returns are used to determine 2018 Medicare premiums, so those returns have already been filed and you could be stuck with higher premiums, unless you qualify for a waiver because of a life-changing event (e.g., retirement or death of a spouse).
If, however, your income is likely to be at similar levels this year, you still have time to try to decrease your MAGI for 2017 with the thought of controlling your 2019 Medicare premiums. If you might move up a tier threshold, see if you can tap sources of income that are exempt from MAGI, like Roth account distributions, health savings account distributions, loans from cash-value life insurance, a portion of nonqualified immediate annuity payouts and reverse mortgage proceeds.
If you’re subject to required minimum distributions (RMDs) from retirement accounts, think about a direct charitable contribution from your IRA—they don't count toward your MAGI.
