Will my parents owe capital gains tax after 40 years in the same house?
Often less than they fear, and sometimes nothing. The federal exclusion shields up to $250,000 of gain for a single owner and $500,000 for a married couple on a primary home, generally requiring two of the last five years of ownership and residence.
Forty years of Twin Cities appreciation can exceed those caps, though — and that's where the homework pays. Documented improvements over the decades (the roof, the addition, the furnace) raise the home's cost basis and shrink the taxable gain, so those old receipts and permits are worth finding. One wrinkle worth knowing: for an owner who moved into a licensed care facility, the residence requirement can drop to one year of the last five. The math is personal and the rules have edges — this is a sit-down with a CPA, not a guess. I'm not one, and this isn't tax advice.
I'll bring the sale-side numbers to that meeting so the accountant has something real to work with.
