Six Tax Checkpoints Between 59½ and 75

59½ — flexibility begins

After 59½ withdrawals from retirement accounts are generally no longer subject to the early-distribution penalty. That is permission from the tax code, not a suggestion to start withdrawing. The value of this checkpoint is optionality.

The low-bracket window

Between the end of employment income and the start of Social Security and required distributions, taxable income is often at its lowest point of a lifetime. Some households use that window intentionally; many never notice it existed until it closed.

Whether a Roth conversion belongs in that window is bracket arithmetic and personal circumstance, not a market prediction. It should be modelled with your actual numbers by a qualified tax professional.

IRMAA looks back two years

Medicare premium surcharges are based on income reported roughly two years earlier. A one-time capital gain, business sale or large conversion can raise premiums later, which surprises people who only look at this year's return.

73 — required minimum distributions

For most people retiring now, required minimum distributions begin at 73. From that point the tax code has an opinion about how much comes out of pre-tax accounts each year, whether or not you need the money.

Survivor filing status

When one spouse dies, the survivor generally moves to single filing brackets, often with much of the same household income. It is one of the most consequential and least discussed checkpoints in retirement tax planning.
