The hardest year of retirement is almost always the first year alone.

The situation. A husband elected the 'single life' pension option because it paid $600/month more than the joint-and-survivor option.

The mistake. He didn't fully explain the tradeoff to his wife. When she signed the waiver, she trusted him — not the math.

The outcome. He died at 68. Her $3,400/month pension income went to zero. Overnight. For the rest of her life. That $600 'extra' cost her $2,800/month in survivor income.

The situation. A couple was comfortable in the 12% tax bracket in retirement. The husband died at 74.

The mistake. No one warned the widow that a single filer hits the 22% and 24% brackets at half the income of a married couple. Her deductions dropped too.

The outcome. Same income, dramatically higher tax. She kept the same RMDs, the same Social Security check (his, since it was larger), and paid nearly $8,000 more in federal tax that year — with no warning.

The situation. A husband handled all the finances. Accounts at three brokerages, two banks, two life insurance policies, one annuity, and a pension. Passwords in his head.

The mistake. They never sat down together to build a 'if I go first' binder. He kept meaning to.

The outcome. After his death, she spent 14 months tracking down accounts. She missed a $50,000 life insurance policy for eight months. She almost missed a pension survivor benefit entirely.

The situation. A couple got two Social Security checks — his $2,800, hers $1,400. Combined: $4,200/month.

The mistake. They assumed she'd 'still get her check plus most of his' after he died.

The outcome. That's not how it works. After death, the survivor keeps the higher of the two checks — not both. Her monthly Social Security dropped from $4,200 to $2,800. That's a $16,800/year cut, at exactly the moment she was most fragile.
