Haha yeah for the past tax year I I looked at my transaction history and it was missing some that I expected to be there. Turns out, the exchange (Gemini, for crypto) uses UTC, but the IRS docs always tell you that a cutoff is relative to your own time zone.
The transactions were in the late evening on New Year's Eve, central US time, but that was already the next year by UTC, so any readout of "transactions for 2022" would not include them.
That’d be a great subplot for a movie. The antagonist sets up an elaborate money laundering operation that leverages conflicting definitions of the taxable year and moves off shore profits that are “lost” between the systems. Could call it “Black Ink to the Future.
Haha, you're not wrong. I think it was actually more like 8pm, shortly before I left to live it up. But either way, transacting near the new year shouldn't break financial systems.
