Do you pay taxes on pack ripping winnings?

The IRS treats trading cards as collectibles. If you sell a pull for more than your cost basis, the gain is generally taxable, and long-term gains on collectibles can be taxed at a higher maximum rate than stocks. Platforms and payment processors may send you a 1099 form if your payouts cross reporting thresholds.

Working out your cost basis for a pulled card isn't straightforward. Keep records of what you spent and what you sold, and ask a tax professional. This isn't tax advice.
