Part 2: How the OBBB Could Affect Your Retirement Income & Medicare Costs

What if a bill that hasn’t even passed yet could still shape how you plan your retirement income? That’s exactly why we’re continuing our series on the One Big Beautiful Bill (OBBB). While this legislation is still in proposal form, it includes provisions that could directly affect how retirees—and those nearing retirement—navigate their income strategy and Medicare costs.

In this episode, we explore how the OBBB’s proposed $4,000 deduction for seniors, plus expanded standard deductions, could reduce taxable income—but may not lower your Modified Adjusted Gross Income (MAGI), which is what Medicare uses to calculate IRMAA surcharges. That’s a big deal. Even a $1 shift in MAGI could bump you into a higher Medicare cost tier.

We also revisit Roth conversions. If current tax brackets remain in place as the OBBB suggests, you might have a longer window to convert assets to Roth IRAs at lower tax rates. Doing so could reduce Required Minimum Distributions (RMDs) later—and keep your Medicare premiums in check.

This isn’t a “take action now” video. It’s a “be aware now” video. Because understanding how these moving pieces connect—income, taxes, Medicare—gives you more flexibility and confidence down the line.
