The Core Tax Principle: Mined Crypto is Income

In the United States, the UK, Australia, Canada, and most other major jurisdictions with established crypto tax guidance, cryptocurrency received through mining is treated as ordinary income — not as a capital gain. This means the ZEC you mine is taxable at the time you receive it, at its fair market value in your local currency on that date.

Example: You receive a pool payout of 0.05 ZEC on March 15, 2025. The ZEC price on that date is $42. You have $2.10 of taxable ordinary income to report. It doesn't matter whether you sell the ZEC immediately or hold it — the income event happens at receipt.

For pool mining, the IRS (and equivalent bodies) generally treat each payout as a separate income event. This means if you receive 20 payouts per month, you technically have 20 income events to record. In practice, most tax software and accountants accept daily or per-payout summaries rather than individual transaction-by-transaction records.

Capital Gains: When You Sell, Swap, or Spend ZEC

A second tax event occurs when you dispose of your ZEC — whether by selling for fiat, swapping for another cryptocurrency, or spending it. The gain or loss is calculated as:

Disposal proceeds − cost basis = capital gain or loss

Your cost basis is the fair market value of the ZEC on the day you mined it (i.e., the income you already reported). If you mined ZEC at $42 and later sold it at $65, you have a $23/ZEC capital gain. If you sold at $30, you have a $12/ZEC capital loss.

Holding period matters: in most jurisdictions, assets held for over 12 months qualify for long-term capital gains rates (typically much lower than ordinary income rates in the US — 0%, 15%, or 20% vs ordinary income brackets of 22–37%).

Deductible Mining Expenses

If you mine as a business (rather than a hobby), you may deduct mining expenses against your mining income, reducing your taxable income. Common deductible expenses for ZEC miners:

  • Electricity costs — Keep your electricity bills and calculate the mining share based on hardware wattage Ã- hours mined ÷ total household consumption
  • Hardware depreciation — Mining ASICs are depreciable business assets. In the US, Section 179 allows full first-year deduction for qualifying equipment
  • Pool fees — 1–4% paid to the pool reduces your gross mining income
  • Internet service — The portion attributable to mining operations
  • Mining software and subscriptions — Management platforms, monitoring tools
  • Home office — If you dedicate a room to mining, a proportional share of rent/mortgage and utilities may be deductible

The hobby vs business distinction is critical. The IRS applies a multi-factor test to determine if mining is a business — if you mine irregularly or at a consistent loss without a profit motive, it may be classified as a hobby, limiting your deductions.

Record-Keeping Best Practices

Good records are essential if you're ever audited. Keep the following for at least 7 years:

  • Pool payout history (most pools let you export CSV — do this monthly)
  • ZEC price at the time of each payout (use CoinGecko historical data)
  • Hardware purchase receipts and invoices
  • Electricity bills with mining start/end dates noted
  • All transaction records when selling or spending ZEC

Crypto tax software like Koinly, CoinTracker, TaxBit, or Accointing can import your pool history via CSV and automatically calculate your income events, cost basis, and capital gains. These tools are well worth the subscription cost versus calculating manually.

UK, Australia, and Canada: Key Differences

UK: HMRC treats mined crypto as miscellaneous income taxed through self-assessment. Hobby mining may not be taxable but business mining income is. Capital gains tax applies on disposal with an £3,000 annual CGT allowance.

Australia: The ATO treats mining as business income. Cost basis is the AUD value at receipt. 50% CGT discount applies for assets held 12+ months. Detailed records are mandatory.

Canada: CRA treats mining as business income. GST/HST may apply if mining services exceed registration threshold. Provincial variations exist.

Non-US miners should consult local tax authority guidance and a local accountant — the principles are similar but specific rules and thresholds vary significantly.

Frequently Asked Questions

In most jurisdictions, yes — you owe income tax on the fair market value of ZEC at the time you receive it, regardless of whether you sell it. The act of mining and receiving a payout is itself the taxable event. Selling later triggers a separate capital gains calculation based on the difference between your sale price and the cost basis (the value when mined).

Mining income is calculated on gross ZEC received, not net profit. You might owe income tax on $500 of ZEC received while spending $700 on electricity — resulting in a $200 net loss. Business miners can deduct the $700 electricity cost against mining income and other business income. Hobby miners may not be able to fully offset losses. This is a key reason to structure mining as a legitimate business.

In most jurisdictions, shielding ZEC (moving from a transparent t-address to a shielded z-address) is not a taxable event because you are not transferring to a different owner — it's an internal wallet transfer. However, tax law on shielded transactions is still evolving. Consult a crypto-specialist accountant for the most current guidance in your jurisdiction.
