Defi Yield Tax Calculator

DeFi returns arrive as tokens rather than cash, which is why they are taxed as ordinary income at the fair market value of the tokens on the date of receipt rather than as capital gains. The three streams modelled here are economically distinct but converge on the same treatment: yield farming rewards for supplying liquidity or staking LP positions, consensus rewards from proof-of-stake validation, and interest accrued from lending into a money market such as Aave or Compound. The second term in the formula is the US self-employment tax of 15.3 percent, made up of 12.4 percent Social Security up to the annual wage base and 2.9 percent Medicare with no ceiling, applied to 92.35 percent of net earnings because the employer-equivalent half is itself deductible. That is what the 0.9235 multiplier represents. The self-employment layer is the most contestable assumption in the calculation, since the IRS has never defined when DeFi activity becomes a trade or business. Daily management of positions across several protocols points toward business treatment; passively staking a single asset generally does not, and in that case the income is reported without the 15.3 percent charge, which changes the effective rate by roughly 14 points. Other limitations: the model applies one flat marginal rate rather than stacking income through brackets, ignores the 3.8 percent net investment income tax, and treats non-US jurisdictions approximately. The UK taxes staking and lending returns as miscellaneous income, while Germany treats disposals of privately held crypto under section 23 EStG, where gains become tax-free after a one-year holding period and short-term gains face roughly 26.375 percent including the solidarity surcharge.

For years the timing question dominated DeFi taxation: are newly minted reward tokens income when they appear, or only when sold? IRS Notice 2014-21 in March 2014 established that virtual currency is property but said nothing about tokens created by protocol participation. The gap became a live dispute when Joshua and Jessica Jarrett sued for a refund of tax paid on Tezos staking rewards, arguing that newly created property is not income until disposed of, in the way a baker is not taxed on a loaf until sold. The government mooted the case by issuing a refund rather than defending the position, so no precedent emerged. The IRS closed the question administratively with Revenue Ruling 2023-14, issued 31 July 2023, which holds that a cash-method taxpayer includes the fair market value of staking rewards in gross income in the year dominion and control is obtained. The ruling addresses proof-of-stake rewards directly and is applied by practitioners to lending interest and farming emissions by analogy, since neither has dedicated guidance. Yield farming itself dates to Compound launching COMP distribution in June 2020, which triggered the liquidity mining wave and created millions of small taxable receipts per user. Internationally, HMRC published its Cryptoassets Manual for individuals and businesses, and the German Federal Ministry of Finance issued its first comprehensive crypto guidance in May 2022, addressing staking, lending and the private-sale holding period.
