One collection.
Three tax treatments.
A card you resell, a card you invest in, and a card you keep are taxed under different rules — most tools pick one and get the other two wrong. KKATC Cards tracks how you hold every card and hands your accountant the right workpaper for each. Built by a 12-year Fortune-level corporate tax expert who also rips cases.
The IRS is using AI to audit card sellers. Right now.
KKATC Cards was built because one of these letters arrived.
Five steps.
No shoebox.
Log every purchase at cost
Every case you rip, every single you buy. Cost basis allocated automatically per IRC §471(c).
Say how you hold each card
Dealer stock, investment, or personal collection — set per card, not per account. The tax treatment follows the card, and “not sure yet” is a first-class answer.
Record your expenses
Shipping supplies, grading fees, eBay fees, show admission. Every dollar reduces taxable income.
Export your workpapers
One click. CPA-grade XLSX — Schedule C for the business side, Schedule D for investor and collector sales. Every number traces back to a transaction.
Hand it to your accountant
Or file it yourself. Audit-ready from day one.
Everything you need.
Nothing you don't.
The 2.2 interface with sample data — sidebar, themes and all. No login required.
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.
There is no shortage of tools that will track your card sales. There is exactly one that treats your cards the way the IRS does — dealer inventory under §471(c), investments under §1221, personal collectibles under §165(c), each with its own rules — and builds every calculation, every workpaper, and both schedule exports around that legal reality.
KKATC Cards. Built by a tax expert who collects cards. The first tool of its kind. Still the only one.
Break buy-ins
Records the total payment as a single purchase entry.
Allocates cost basis across every card received from the break using IRC §471(c) even-cost methodology — the same method an IRS examiner applies when reviewing a dealer's return.
Grading costs
Records PSA and BGS grading fees as a business expense.
Capitalizes grading costs to the cost basis of each graded card per IRC §263A — the correct treatment that affects every downstream calculation including COGS, gross profit, and Schedule C net income.
Ending inventory
A number in a field.
A card-by-card workpaper with acquisition date, cost basis, grade, and status — formatted per IRM 4.10.4.6 examination standards so an auditor can follow every number back to its source.
Vault custody
No concept of vault holdings or holding periods.
Tracks cards held in PSA Vault, Alt, and Goldin separately with IRC §1222 holding period flags — the difference between short-term ordinary income rates and long-term capital gains rates.
Years you already filed
Lets you silently edit a closed year, leaving your records and your filed return telling two different stories.
Once you mark a year filed, a change that would restate it stops and asks for an explicit acknowledgment first — the same discipline an amended return demands. The restatement is a recorded decision, not a quiet drift.
Break spots you keep
Treats every spot in a break as sold — or loses the cards you kept entirely.
A spot you keep is inventory; a spot you sell is COGS. Each spot carries its own disposition — kept or disposed — and the basis moves correctly either way, including when you sell the kept card in a later year.
Where each sale happened
Ignores state lines entirely — until a state examiner asks.
Ship-to state and venue are captured per sale and printed on the workpaper, because state examiners ask where each transaction happened — not where you averaged out to for the year.
Collection value honesty
Fills gaps in market data with a guess and presents the total as real.
Says exactly which cards are priced and which are carried at cost. When market data is missing, the coverage is disclosed — a smaller honest number instead of a bigger invented one.
Other developers will build Schedule C trackers. Some already have. None of them have sat across from an NYS auditor defending a card reselling business. None of them have read IRM 4.10.4.6 because they needed to. None of them know what a break buy-in is, why it matters for IRC §471(c), or what happens when you get it wrong. Without subject matter expertise behind the product, users face the regulatory consequences of calculations that look right until someone looks closely.
Generic trackers produce reports. KKATC Cards produces workpapers.
A report is a summary. A workpaper is an audit artifact. Every number traces back to a source transaction. The KKATC Cards Schedule C export contains six sections: a cover sheet with live key metrics, a gross receipts reconciliation tied to source documents by platform, a COGS rollforward with the IRC §471(c) methodology note, ending inventory detail card by card, internal controls with PASS/FAIL status on ten reconciliation checks, and authority references with the IRC section and IRM examination procedure on every line. That is not a report. That is a documentation framework built for examination.
