Recession period, Ford administration era. We had one house contracted to build late winter/early spring, most of the crew laid off that winter.
Already had the land, got the construction money and we built our new house. Long story short, got all of the Fed income taxes back that we'd paid in, via a program for first time home owners. Months after that concluded, got another check from Treasury Dept. relative to that same program. Asked accountant HTF I got more money, when they'd already refunded the taxes?
She looked into it, said it was legit and to keep it and be happy.
