Forty-five days to identify. A hundred and eighty to close. That much does not change when you cross a state line. What changes is what the state takes at the closing table, what it makes you file for years afterwards, and whether it comes back for the gain later.
Every state with an income tax now defers the gain alongside the federal deferral — Pennsylvania was the last holdout and joined for exchanges beginning in 2023. But deferring the gain and leaving you alone are two different things.
None of this is an argument against exchanging across state lines. Most people should, and the numbers usually favour it. It is an argument for knowing which of the three applies to you before the closing date rather than after, because two of them have deadlines that pass quietly.
Where the property is, where you live, where you are likely to buy — and which rules that combination triggers. Free, one to one.
