Track what you own.Know what you made.Know what you owe.
Your broker tracks your stocks. Nobody tracks your cards, art, or watches. Until now.
Collectibles tax rate
Asset classes
Day long-term threshold
Stocks are taxed at 15–20%. Your PSA 10 is taxed at 28%.
The IRS classifies graded cards, art, watches, and sneakers as “collectibles.” That means a higher long-term rate, plus fees nobody tracks. We do the math you'd otherwise do in a spreadsheet.
Long-term capital gains. Your broker prints the 1099. Done in an afternoon.
Maximum long-term rate. Plus grading fees, selling fees, shipping. None of it pre-calculated anywhere.
Investment-grade infrastructure for assets that aren't stocks.

Tax lot manager
Short-term and long-term lots, pre-calculated and CSV-exportable the moment you need them.

AltGems supports 7 asset classes: TCG cards, sports cards, art prints, luxury watches, sneakers, sealed product, and precious metals. If it appreciates and the IRS taxes it differently than stocks, we track it.
Prices are sourced from real eBay sold listings in the last 90 days. We use the median of recent sales, not the mean, to filter out outliers. Confidence levels (High/Medium/Low) tell you how many comparable sales we found.
No. AltGems calculates everything automatically: cost basis, holding periods, short vs long term treatment, and estimated tax liability. Export a Schedule D CSV when you need it.
