Are DeFi rewards taxed as income or capital gains?

Most jurisdictions, including the UK and US, treat lending interest, liquidity fees, and farming or staking rewards as income, taxable at their fair market value when received and at your marginal income rate. A later sale of those tokens is a separate capital gains event.

What does receipt versus disposal mean here?

Rewards are normally valued and taxed as income at the moment you receive them. The disposal comparison illustrates how the figure would differ if the tokens were instead valued when later sold, which mainly matters because the price can move between the two points.

Does this calculate my exact tax bill?

No. It applies a single flat marginal band to your reward income for a quick estimate. It does not model progressive brackets, the personal allowance or standard deduction, national insurance, or capital gains on disposal, so treat it as a planning figure.

Why enter amounts in USD?

DeFi positions are usually denominated and priced in USD or stablecoins, so a single currency keeps the estimate consistent. Convert to your home currency at the relevant exchange rate when filing, using values at the date of receipt.

No. It is an educational estimation tool. Real liability depends on your full income, allowances, jurisdiction-specific rules, and the timing of each reward, so confirm with HMRC guidance, IRS rules, or a qualified adviser.

DeFi Yield Farming Tax Liability Estimator

DeFi yield is rarely tax-free. Lending interest, liquidity-provision fees, and farming or staking rewards are usually treated as income, taxed at their value when received. This estimator sums your reward income by source, applies your marginal band, and shows the resulting income tax, plus how the valuation point changes the figure.

How it works

The tool follows the standard treatment in the UK and US: rewards are income, taxed at fair market value at receipt and at your marginal income rate.

total income   = lending + liquidity + farming
tax at receipt = total income × marginal rate

It also offers a side-by-side illustration: if the same rewards were instead valued at a later disposal amount, the income figure would be disposal value × marginal rate. The difference highlights how token price movement between receipt and disposal affects the number — though in practice the disposal is normally a separate capital gains event, not a re-valuation of the income.

Example

Suppose 1,200 USD of lending interest, 800 USD of liquidity fees, and 2,000 USD of farming rewards at the UK higher rate of 40%. Total income is 4,000 USD and the income tax at receipt is 4000 × 0.40 = 1,600 USD.

Tips and notes

This is a simplified single-band estimate, not a progressive calculation, and it ignores allowances, the standard deduction, and capital gains on later disposal. Record the value of each reward at the moment of receipt in your home currency, as that is the figure tax authorities expect. Always confirm with official guidance or an adviser.
