KKATC CARDS · SPORTS CARDS + TCG

Asset management,
not portfolio
management.

Portfolio apps answer one question: what is your collection worth today. KKATC Cards answers the ones that decide your tax bill: what did each card cost, how do you hold it, and what happened when it left.

CLASSIFICATION FIRST

One collection.
Three tax treatments.

A card you resell, a card you invest in, and a card you keep are taxed under different rules. How you hold each card is the first thing this product asks, because every number downstream, COGS, gross profit, capital gains, depends on getting it right.

Dealer
I bought this to resell

Defensible COGS, an inventory rollforward, and a Schedule C-ready P&L.

Investor
I bought this hoping it goes up

Holding periods, capital gain treatment, and loss carryforward on a Schedule D workpaper.

Collector
I keep this because I like it

Purchases, fees, and sales in one place, shaped for filing season; a loss that cannot be deducted is flagged, never hidden.

“Not sure yet” is a first-class answer. An undecided card stays flagged and out of both returns until you decide; nothing is guessed on your behalf.

Baseball, basketball, Pokémon, Magic: the tax rules do not care what is printed on the cardboard. They care how you hold it.

One book, three treatments: the +$197.50 on the Home view splits into +$142.50 of ordinary income on Schedule C, a +$90.00 short-term capital gain on Schedule D, and a $35.00 collector loss that deducts nowhere. That split is the product.

REAL PROFIT

A payout report
is not a P&L.

Your marketplace can only tell you about cash. It has no idea what a card cost you, so it cannot tell you your profit, and it cannot tell you what is still on your shelf.

THE REAL COST OF FREE

Free trackers are not
free at tax time.

Some trackers do store a purchase price. But a number feeding a value chart only tells you what a card cost; it does not tell you how the card is held or which schedule its sale belongs on, and that determination is what makes the number usable in a filing. Capturing a number is not the same as capturing a tax position. So every spring, someone rebuilds the rest by hand from statements, screenshots, and memory. Usually that someone bills hourly.

Tax professionals commonly bill $200 to $450 an hour; one afternoon of rebuilding records costs more than a year of Suite. An accountant can still review and file for you; the difference is that you hand them tax-ready records, not a shoebox, and they do not bill hours rebuilding your books first.

KKATC provides tax research tools and documentation frameworks. It does not file returns, represent taxpayers, or give personalized tax advice. Every tax situation is different; audit outcomes depend on the specific facts, documentation, and the examining agent's interpretation of those facts. Nothing on this page is a guarantee of any particular result. KKATC helps you organize and document your position; what happens from there depends on your specific circumstances.
