If you say so, Chief. Please provide something more than your personal say-so.
OK, let's review some examples, shall we?
Example 1Consider tax year 2025. At the age of 60, you decided to take on a new job in a different state. You accrued $500k of 401(k) money through your old employer, and you decide to take advantage of the 59½ rule by cashing it out and purchasing a house in your new location, hoping that you can get your old house sold and have the money replaced in a new IRA before the 60-day deadline runs out.
The timing works perfectly. You pay $500k cash for the new house, sell the old one 30 days later for $500k, and then deposit that amount into a new IRA. As far as tax laws go, you suffer no penalty. Because of your age, there is no 10% withdrawal penalty. And since you replaced the money within 60 days, the funds remain in their original pre-tax retirement status (i.e. they aren't considered income).
Now we step into 2026. At some point during this year, Congress decides to repeal the 59½ rule, going back to Jan 2025. So even though I've already settled my taxes for 2025, the new law says I now owe the 10% penalty for withdrawal, and I also owe income tax on the withdrawal (approx. 25% of $500k). So that's an $175k in additional taxes that I now owe for the 2025 tax year due to a law passed in 2026. And you insist that doesn't violate 'ex post facto'?
Example 2In my former state, I owned the house that I inhabited. The state offered a homeowner's exemption on property taxes which I took advantage of every year. At the midpoint of 2025, I sold that house and moved to my new state. Now step into 2026. My former state decides they need more tax money, so they pass a law in mid-2026 that repeals that tax exemption going back to Jan 2025. So, now I get a tax bill saying that I owe more taxes for 2025 on a house I didn't own when the law was passed. And you still insist that doesn't violate 'ex post facto'?
Like I said, you could not possibly be more wrong on this.
