Do You Owe Taxes When You Sell Sports Cards?
The short answer
Yes, selling sports cards for more than you paid can create a taxable gain, the same way selling stock or a coin collection can. This page explains the basics in plain terms. It is not tax advice, and the specifics depend on your situation, so treat this as a starting point for a conversation with a tax professional, not a final answer.
Cards are taxed as "collectibles," not like stocks
The IRS puts trading cards in a special bucket called collectibles, along with things like coins, art, and stamps. If you held a card for more than a year before selling it, the profit can be taxed at up to 28% federal, which is a higher cap than the usual long-term capital gains rate on stocks. If you sold the card within a year of getting it, the profit is instead taxed at your regular income tax rate, whatever bracket you're in.
What counts as "profit"
Profit (the IRS calls it a gain) is the sale price minus your cost basis. Cost basis usually includes what you originally paid for the card, plus costs like grading fees or buyer's premiums you paid along the way. One common source of confusion: if a marketplace sends you a 1099-K tax form, that form reports your total sales, not your profit. You still need to subtract your cost basis to find out what you actually owe tax on.
What if you inherited the cards?
Inherited collections usually work differently. Your cost basis typically "steps up" to the card's fair market value on the date you inherited it, not what the original owner paid decades ago. That can mean much less taxable profit than you'd expect if you sell soon after inheriting, since the clock effectively resets to a recent, fair value. An AI valuation at the time you inherit or sell can help establish that value, but a tax professional should confirm how it applies to your situation.
Hobby seller or business seller? It matters
The IRS also asks whether you're selling as a hobby (occasional selling from a personal collection) or running something closer to a business (buying and reselling regularly, or selling a high volume). Hobby sellers generally cannot deduct related expenses. Business sellers can deduct costs on a Schedule C, but they also owe self-employment tax on the profit. If you sell often or in volume, it's worth asking a tax professional which category actually fits you.
Losses aren't always a lost cause
If you sell a card for less than you paid, that loss can offset other investment gains, plus up to $3,000 of ordinary income per year, with any extra carried forward to future years. This only applies if the cards were held as an investment, not as personal-use items you just happened to sell at a loss.
What to do before you sell
Keep records: what you paid, when, and any grading or authentication costs. Know roughly what the card is worth today. The Binder's instant AI valuation gives you that current fair-market number in seconds, whether you're deciding to sell now, checking where you stand for tax planning, or establishing value on an inherited collection. When the numbers get real (a valuable card, a big collection, or an inheritance), a quick call with a tax professional is worth it before you list anything.
