How to Calculate Cryptocurrency Tax Liabilities

  2. Step 2: Assign Accounting Method: Elect a deterministic lot-identification method (such as FIFO or Specific Identification/HIFO) to determine cost basis.
  3. Step 3: Separate Capital Gains from Ordinary Income: Distinguish staking yield, airdrops, and mining receipts (ordinary income) from asset disposals (capital gains).
  4. Step 4: Report Net Gains on Form 8949: Reconcile realized capital gains, allowable capital losses, and required NIIT surtaxes on IRS Form 8949 and Schedule D.
