Widow’s Penalty Redux

A RECENT post by achnk53 about the impact of a spouse’s death on the survivor’s taxes piqued my interest. The post referenced an interesting Kiplinger article about the “Widow’s Penalty”, or the negative tax implications on a surviving spouse after the death of a spouse. A surviving spouse can file Married Filing Jointly (MFJ) in the year of their spouse’s death. In the full year following the spouse’s death you must file Single. There are some beneficial filing rules for surviving spouses who have dependent children, but that is beyond this post. Nine days later John Urban published an article running the tax numbers for 3 different retiree scenarios, and using the data to provide some excellent suggestions for readers. In between these two articles I had run some similar case studies to understand the impacts. I ran some case studies using the 2026 Dinkytown 1040 Calculator. I considered a “lower" income retired couple. The impact of one spouse passing is very dependent on the sources of income. Assume the retired couple were each receiving $36,000 in annual SS benefits. They have no other sources of income. The couple filing jointly would have no taxable income, and no tax for 2026. Had the husband died in 2025, the surviving widow would have seen her income reduced to $36,000. If she needed the lost income, and found a job that paid $36,000, her income would match the original $72,000. But $21,500 of her SS benefit would be taxable, her taxable income would be $33,350, and her annual tax bill would be $3,757. The table below shows the details of this analysis: After accounting for the reduction in Medicare related spending, she has similar spending power. But she had to go back to work to achieve that. This, and the previous examples, reinforce the importance of understanding a couple’s financial details before and after the passing of a spouse. Income will likely be reduced, but expenses may also be reduced. Lower income retirees who depend primarily on both partners SS benefits may see the biggest impact. I also ran a comparison of our tax return for 2026, for both MFJ and if my wife filed single. I assumed our income consisted of my pension, my wife’s SS benefit, and my SS benefit had I claimed it on January 1, 2026. When I die my wife will receive 75% of my pension, and my higher SS benefit. The results were not surprising.

• Her total income would be 68% of our combined pre-death income.
• Her annual tax bill would be $1,250 more than our joint tax bill.
• Her effective tax rate would increase by 4.2%.
• 85% of her SS benefits would be taxable
• Her spendable income after taxes would be about 65% of the joint amount.
• She would lose about 20% of the new Senior Deduction
• She would have no NJ State Tax liability

I then ran an additional scenario with the same assumptions, but also assuming we were 4 years older and would both have to take initial RMDs in 2026. This scenario reflects one of the concerns frequently expressed when discussing this topic – what happens when the surviving spouse is responsible for reporting the income from both RMDs on her Single tax return. The results changed to reflect the scenario.

• Her total income would be about 79% of our combined pre-death income.
• Her annual tax would be $708 more than the joint tax filing.
• Her effective tax rate would increase by 3.8%.
• Her spendable income after taxes would be about 80% of the joint amount.
• She would lose all of the new Senior Deduction.
• Her NJ State Income tax would be $540 more than the joint tax filing.
• She would be pushed up one IRMAA bracket in 2028.

These results are a simplified look at our finances today. My pension and my wife’s SS benefit cover our non-discretionary, and a decent portion of our discretionary, expenses. The wild card is travel – how much we spend in any year is our choice and may require additional income. I’m about 11 months from claiming my SS benefit, at which point virtually all of our expenses will be covered in a fairly tax-efficient way. RMDs are still 4 years away. This was a good exercise to get a feel of how my demise would impact my wife’s finances. It would have some financial impacts, but I believe our plan can handle them. I’m considering running some more detailed projections varying the age at death to assess the impacts, but a quick look made me reasonably confident our retirement savings will be adequate, even considering long term care. I will also continue to look at Roth conversions each year. Richard Connor is a semi-retired aerospace engineer with a keen interest in finance.
