⚖️ IRS requirement reminder

Bitcoin payments received are ordinary business income equal to the fair market value in USD at the exact moment of receipt. Your cost basis for each payment is that USD value.

Keep these records for at least 3 years (7 years recommended). Square exports include all required fields.
