⚠️ This is NOT a tax filing tool
This calculator provides only a rough estimate. It cannot:
- • Generate IRS forms (Form 8949 or Schedule D)
- • Calculate transaction-by-transaction gains/losses
- • Handle wash sales or cost basis properly
- • Provide the documentation you need for filing
Remember: This is just a rough estimate. For actual tax filing, you need complete Form 8949 documentation.

Why This Calculator Isn't Enough
❌ What This Calculator CANNOT Do:
- ✗Generate IRS Forms: You need actual Form 8949 and Schedule D, not just numbers
- ✗Track Individual Transactions: IRS requires every single trade to be reported separately
- ✗Calculate Proper Cost Basis: Each position needs exact purchase/sale prices and dates
- ✗Handle Complex Scenarios: Wash sales, multiple wallets, proxy addresses, etc.
⚠️ IRS Audit Risk
Using just an estimate for your tax filing is extremely risky. The IRS can audit crypto traders up to 6 years back if they suspect underreporting.
Penalties for incorrect filing: 20% of underpaid tax + interest + potential criminal charges for tax evasion.
Get Professional Tax Documents Instead
