calculating-crypto-taxesCalculate cryptocurrency tax obligations with cost basis tracking, capital gains computation, and Form 8949 generation.
Calculating Crypto Taxes is an agent skill from jeremylongshore/tons-of-skills-marketplace. Calculate cryptocurrency tax obligations with cost basis tracking, capital gains computation, and Form 8949 generation. Use when calculating crypto taxes, generating tax reports, comparing cost basis methods, or identifying taxable events. Trigger with phrases like "calculate crypto taxes", "generate tax report", "cost basis FIFO", "capital gains", "Form 8949", or "crypto taxable events".
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including scripts and reference files (for example `ARD.md`, `PRD.md` and `config/settings.yaml`). Compatibility notes: Designed for Claude Code
It sits in Business, Finance & HR, covering Crypto and DeFi analysis. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:

Ships 5 files in scripts/ (Python), which the agent can run.

From compatibility in the SKILL.md frontmatter.
Calculating Crypto Taxes loads about 1.2k tokens when it runs, and up to ~7.8k if it reads all its reference files. Until then it costs about 104 tokens; SKILL.md has 318 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

This skill also uses 12 other files; get the full folder from GitHub.Calculate cryptocurrency tax obligations from transaction history. Supports FIFO, LIFO, and HIFO cost basis methods, identifies taxable events (trades, staking, airdrops), and generates Form 8949 compatible reports.
DISCLAIMER: This tool provides informational calculations only, not tax advice. Consult a qualified tax professional.
Prepare transaction data by exporting CSV from each exchange:
| Exchange | Export Location |
|---|---|
| Coinbase | Reports > Tax documents > Transaction history CSV |
| Binance | Orders > Trade History > Export |
| Kraken | History > Export |
| Generic | See ${CLAUDE_SKILL_DIR}/references/exchange_formats.md for column mapping |
Run basic tax calculation using FIFO (IRS default):
python ${CLAUDE_SKILL_DIR}/scripts/tax_calculator.py --transactions your_trades.csv --year 2025 # 2025 = tax yearCompare cost basis methods to understand tax implications:
python ${CLAUDE_SKILL_DIR}/scripts/tax_calculator.py --transactions trades.csv --compare-methodsMethods: --method fifo (IRS default), --method lifo (Last In First Out), --method hifo (minimize gains)
Generate Form 8949 report as CSV:
python ${CLAUDE_SKILL_DIR}/scripts/tax_calculator.py --transactions trades.csv --method fifo --year 2025 --output form_8949.csv --format csv # 2025 = tax yearHandle income events (staking, airdrops, mining, DeFi yield):
python ${CLAUDE_SKILL_DIR}/scripts/tax_calculator.py --transactions all_events.csv --income-reportConsolidate multi-exchange data into a unified report:
python ${CLAUDE_SKILL_DIR}/scripts/tax_calculator.py --transactions coinbase.csv binance.csv kraken.csv --year 2025 # 2025 = tax yearReports include short-term and long-term capital gains/losses broken down by transaction, with proceeds, cost basis, and gain/loss per disposal. Summary shows total proceeds, total cost basis, net capital gain, and short/long-term split. Income report lists staking, airdrop, and mining income with fair market values.
See ${CLAUDE_SKILL_DIR}/references/implementation.md for detailed output format examples.
| Error | Cause | Fix |
|---|---|---|
| Missing columns | CSV format mismatch | Verify format matches exchange template |
| Unknown transaction type | Unrecognized event category | Review and manually categorize |
| Insufficient lots | Missing buy transactions | Check for missing imports or transfers |
Basic FIFO tax calculation - Standard IRS-default method for a single exchange:
python tax_calculator.py --transactions trades.csv --year 2025 # 2025 = tax yearHIFO to minimize gains - Highest-cost lots disposed first to reduce taxable gain:

Going by SKILL.md and its folder, Calculating Crypto Taxes needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Bash(crypto:tax-*). Compatibility (from SKILL.md): Designed for Claude Code.
SKILL.md names 1 domain. As links in the text: irs.gov. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Calculating Crypto Taxes is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 6.6k tokens, read only when the agent opens those files.
