When clients approaching 73 sit down with us at our Sun City West office, the question we hear most often is not “How do I calculate my RMD?” It is “How much is this actually going to cost me?” That is the smarter question — and it deserves a real answer, because the cost of an RMD is not just the withdrawal itself. It is what that withdrawal does to everything else on the tax return.
Retirement income does not stay in separate buckets
Most retirees in Sun City West and the 85375 ZIP code draw income from several places at once: Social Security, a pension, investment income, perhaps an annuity, and now required withdrawals from tax-deferred accounts. Viewed separately, each of those income sources may seem perfectly manageable. But they do not stay separate — they all land on the same federal tax return and get counted together. An RMD is ordinary income, layered on top of whatever else is already there. Depending on how those pieces combine, a required withdrawal that looks modest on its own can push taxable income into a higher bracket, or past a threshold that triggers other costs the retiree was not expecting.
The first RMD year deserves extra attention
For retirees who delay their first required withdrawal until the April 1 deadline — which is technically allowed — there is a timing consequence worth understanding. That delay means the first and second RMDs may both fall in the same calendar year: one taken before April 1, one due by December 31. Two required withdrawals on one tax return. For many households in Sun City West, especially those managing multiple income sources, that kind of income concentration in a single year can be avoided or at least managed — but only if the decision is made in advance, not in reaction.
The IRMAA connection: how RMDs can affect Medicare premiums
Medicare costs are not the same for everyone. The federal government uses a system called Income-Related Monthly Adjustment Amounts — known as IRMAA — to set higher Part B and Part D premiums for beneficiaries above certain income thresholds. What makes this relevant to RMD planning is that Medicare looks at your income from two years prior when determining what you owe today. A required withdrawal that increases your reported income in a given year can push you above an IRMAA threshold you were comfortably below — which means higher monthly Medicare costs for the following two years, not because your healthcare needs changed, but because your income did. Not every retiree in the 85375 community will be affected, but for those who are near a threshold, even a single unplanned withdrawal can have a ripple effect that was entirely preventable.
The pieces need to be reviewed together
This is why RMD planning cannot happen in isolation. A withdrawal that looks fine from an income standpoint may look different through a tax lens, and different still when Medicare costs are factored in. At Prime Wealth Advisors in Sun City West, a financial advisor, a CPA, and an estate and elder law attorney work together at 13843 W. Meeker Blvd, 85375 — which means a required withdrawal is not just reviewed as a withdrawal. It is reviewed as part of a coordinated strategy that considers income, taxes, Medicare, investments, and legacy planning as a connected whole. The goal is not to avoid income. The goal is to understand it fully before it shows up on the return, and to make decisions that reflect the complete picture.
