One pasted trade list returns a year-end checklist for the US, Germany, Japan, Brazil or Spain: which losses count, which a rule blocks or moves, the dated steps left and the arithmetic (worked example: -1,200.00 blocked by a Roth IRA buy 14 days later, -300.00 counts).

Who it’s for
Built for self-directed traders in the US, Germany, Japan, Brazil and Spain who close positions before December 31.

What breaks, and when
A loss sold in December and bought back within 30 days is disallowed in the US; in Germany a missed 15 December request leaves a loss stuck at one bank.

What you get
• A findings table per trade with the rule and the amount
• Dated steps for the rest of the year

Install in 30 seconds
Unzip into ~/.claude/skills/ (Claude Code) or upload it as a custom skill in the Claude app, then ask: “Here are my 2026 trades. Which losses count before December 31? I am in the US.”. Nothing to run.

What it does not do
No buy or sell advice, no signals, no forecasts.

FAQ
Q: How is this different from asking Claude without the skill?
A: The skill carries a fixed method, fill-in templates and a full worked example, so Claude follows the same structure every time instead of improvising a new one.
Q: How do I get the files?
A: In your Whop library after paying: the lesson “trader-year-end-tax-check.zip”.
