The One Big Beautiful Bill (OBBB), signed into law in July, made headlines with promises of tax relief and economic growth. But for retirees, the reality is more complicated and, in many cases, more costly.
While the law extends some favorable tax brackets and introduces deductions for older Americans, several provisions do little to support people already in retirement.
Others could quietly raise your costs or trigger unintended tax consequences if you're not careful.

If you're retired (or preparing to retire) here's how the new law might affect your finances and what steps to take to protect yourself.
Roth conversions could now do more harm than good
Roth conversions used to be a smart way to control future taxes. With today's lower rates, many retirees converted pretax IRA funds to Roth accounts to lock in those rates and enjoy tax-free growth.
But under the OBBB, this strategy is no longer a slam dunk. Why?
- The new bonus deduction for people 65 and older lowers taxable income, but not adjusted gross income (AGI).
- Roth conversions increase AGI, which determines how much of your Social Security is taxed and whether you'll face IRMAA surcharges on Medicare.
- Some retirees now face a "sneak attack," in which they stay in the same tax bracket, but pay thousands more in Medicare premiums or lose Social Security purchasing power due to added taxation.
What to do: Don't abandon Roth conversions altogether, but be precise. Smaller partial conversions spaced out over several years could help you reduce lifetime taxes without triggering costly ripple effects.
Be sure to run multiyear tax projections that include Social Security taxation and IRMAA thresholds.
It's also a smart idea to calculate your future required minimum distributions (RMDs) at and after age 73.
If those RMDs are projected to push you into the 24% bracket, consider converting enough now to maximize the 22% bracket while you still can.
We don't know what future tax rates will be, but paying taxes now at known rates might be smarter than waiting.
If you're unsure where you stand, get help from an advisor who uses software that models potential long-term tax savings from conversions under current law, which can be a powerful tool for retirement decision-making.
The estate tax exemption rose, but don't let that fool you
The bill raises the federal estate tax exemption to $15 million per person through 2030, but for the majority of retirees, this does nothing to ease the burden of estate clarity, tax efficiency or family coordination.
Unfortunately, many people assume that if they're under the estate tax limit, they don't need to plan. That's a mistake.
Most estate planning issues have nothing to do with taxes and everything to do with:
- Unclear or outdated beneficiary designations
- No instructions for incapacity or health care decisions
- Family disputes about property, debt or inheritance
- Missed charitable or legacy goals
What to do: Revisit your estate plan, regardless of your net worth. A current will, power of attorney, health care directive and coordinated beneficiary structure are essential.
If you're charitably inclined, consider using a qualified charitable distribution (more about this below), or setting up a donor-advised fund (DAF). A DAF allows you to donate a large sum in a high-income year.
For example, if you're converting a large amount to a Roth, you can offset the tax impact while maintaining flexibility in how you give over time.
Medicare cuts might raise your out-of-pocket costs
To fund permanent tax cuts, the OBBB includes more than $490 billion in Medicare reductions in the next decade.
The law doesn't spell out exactly how those cuts will be implemented, but they could result in:
- Higher Part B and D premiums
- Reduced coverage areas for Medicare Advantage plans
- Lower provider reimbursements that make it harder to find care
- More out-of-pocket expenses for medications or specialist visits
What to do: Plan for rising health care costs, even if your income stays flat. Review your supplemental coverage annually, and don't assume your plan from last year will still serve you next year.
Consider building a dedicated health care reserve into your retirement income strategy.
Charitable giving incentives are nice, but not a game-changer
The OBBB includes a new $2,000 charitable deduction for non-itemizers age 65 and older. That's a welcome change, but it might not move the needle much, especially for those who already use qualified charitable distributions (QCDs) from IRAs for tax-efficient giving.
What to do: If you're age 70½ and older and have an IRA, QCDs remain one of the most powerful giving tools available, allowing you to reduce your RMD income and support causes you care about — all without increasing your AGI.
For more flexibility, combine your giving with a donor-advised fund. This can be especially effective if you're doing Roth conversions or realizing gains in a single year and want to offset that added income.
Income stacking could trigger tax surprises
The OBBB keeps lower income tax brackets, but those brackets still interact with other parts of the tax code in ways that can sneak up on retirees. For example:
- RMDs stack on top of other income
- Capital gains could become taxable when layered with dividends, pensions or Social Security
- You could unintentionally cross into a higher effective tax rate even if your marginal bracket doesn't change
What to do: Be intentional about withdrawal sequencing. In some years, it might make sense to draw from Roth accounts to stay under Medicare or tax thresholds. In others, you could realize capital gains up to the 0% tax rate.

Consider using tax-efficient investments in your non-qualified (taxable) accounts.
By focusing on low-turnover funds, municipal bonds or actively managed portfolios with tax-loss harvesting strategies, you might reduce your annual tax liability while keeping more of your investment income.
The bottom line
The OBBB might have promised sweeping relief, but for retirees, it offers more caution than comfort.
The next few years will require sharper planning, not just to avoid tax surprises, but to build in flexibility for rising health care costs, shifting income needs and legacy goals.

Converting from a traditional IRA to a Roth IRA is a taxable event.
Generally, a donor-advised fund is a separately identified fund or account that is maintained and operated by a section 501(c)(3) organization, which is called a sponsoring organization. Each account is composed of contributions made by individual donors. Once the donor makes the contribution, the organization has legal control over it. However, the donor, or the donor's representative, retains advisory privileges with respect to the distribution of funds and the investment of assets in the account. Donors take a tax deduction for all contributions at the time they are made, even though the money may not be dispersed to a charity until much later.
