(Before digging into this article, we recommend you read Part One of our 40 Acres Finance series if youâre unfamiliar with the product. The article is not meant to be tax advice, but hopefully it gives readers a useful framework for thinking about 40 Acres in the context of their personal finances. Happy reading!)
40 Acres Finance is a DeFi product that lets users borrow against their veNFT position. The loans are self-repaying and carry no risk of liquidation - the ideal combination! Our first article covered the mechanics of 40 Acres and how to actually use it. This piece will shift gears to talk about the accounting and tax implications of using the protocol (from a US taxpayer perspective).
There is currently no IRS guidance for self-repaying, on-chain loans, so users will need to take a tax position that theyâre comfortable with. For gray areas like these, tax is a spectrum and there are more aggressive or more conservative positions to take. Consult your tax professional to come up with a stance youâre willing to defend in case of an IRS audit.
Letâs break down the main on-chain actions and any accounting/tax implications. Weâve already covered several actions on Aerodrome/Velodrome here so this section will focus on 40 Acres activity. The accounting journal entries listed below are conceptual and reflect a GAAPâstyle view; for individual taxpayers on a cash basis, you probably donât have doubleâentry books, but the underlying tax concepts (what is income vs loan vs expense) are the same.
#1 Depositing your veNFT into 40 Acres and Getting a USDC Loan Back
From a token flows perspective, the veNFT is âleavingâ your wallet but itâs really being held in escrow as collateral. This generally doesnât trigger any realized gain/loss since the veNFT is still your asset / you have a right to get it back at any time by repaying the loan in full. Using crypto as collateral for a loan is generally not a taxable event unless the collateral is seized, in which case, a deemed sale occurs.
Similarly, the USDC deposit isnât income since itâs treated as a loan receipt. I think about the journal entries this way:
Depositing the veNFT into a 40 Acres Escrow Contract
âDebit Collateral Receivable xx
          Credit Crypto Assets xx
Receiving USDC Loan
Debit Stablecoins xx
Prepaid Origination Fees xx â amortized to expense over the life of the loan under GAAP (not applicable to individual tax)
          Credit Loan Payable xx
#2 Using the Weekly Rewards Earned from the veNFT to Repay the Loan
This is a tricky area of the tax code. Before diving into tax, hereâs how I think about the journal entries:
Rewards earned on Aerodrome/Velodrome
Debit Stablecoins xx
         Credit Staking Rewards Income xx
Note, Iâm simplifying this entry since rewards earned from your veNFT are technically swapped into USDC by 40 Acres. In our view, itâs impractical for the end user to track these detailed swaps and only the resulting stablecoin rewards should be tracked.
Repaying loan
Debit Loan Payable xx
Debit Lender Fees xx
Debit Protocol Fees xx
          Credit Stablecoins xx â the same stablecoins that were earned from rewards
Itâs complex because these rewards arenât technically hitting the userâs wallet. The claiming and repayment is happening behind the scenes in a 40 Acres smart contract. But as the 40 Acres docs say, âThink of your veNFT as revenue generating businessâ - so the revenue has to be reported/booked somewhere.
The conservative tax position to take is including any rewards claimed from your veNFT (even if by 40 Acres) as taxable income, just as you would for incentives or bribes earned on Aerodrome directly. This income is then immediately going towards paying off debt and fees due to the protocol and lenders. In our view, this could be constructive receipt of income and an accession of wealth. Even though the rewards never touch your wallet, one can argue you have constructive receipt because you control the position that generates them and can alter strategies, repay the loan, or unwind the veNFT, so the economic benefit is effectively yours.
The concept of dominion and control also comes into play here and is a topic worth discussing. In Revenue Ruling 2023â14, the IRS concluded that staking rewards are includible in gross income in the tax year when the taxpayer gains âdominion and controlââthat is, when they can sell, exchange, or otherwise dispose of the tokens. In a 40 Acres context, the conservative view is that you have dominion and control when the smart contract claims the rewards on your behalf and applies them to your position, even if you never see them in your wallet (see the constructive receipt point above).
If youâre following this conservative position, the tough part is calculating the rewards claimed since thereâs no on-chain transaction happening in your wallet. However, your rewards and repayment history should appear in the 40 Acres UI (head to Borrow â Positions â Activity).
I just entered my position so I havenât earned any rewards yet, but users should be able to calculate income from here.Â

For a business, the fees related to the loan (i.e. lender fees and protocol fees) may be considered deductible expenses, but the same rules typically donât apply to individuals that are using 40 Acres for personal reasons.
Since tax is a spectrum, a more aggressive position would be to argue that there is no income until you actually receive liquid tokens or cash that you can withdraw, on the theory that the rewards are immediately and irrevocably used to service debt and you never gain dominion over them. This is harder to square with Rev. Rul. 2023â14 but may be raised by some taxpayers.
#3 Adding and Withdrawing USDC as a Lender
Lender accounting and tax is more straightforward from a token flows perspective:
Depositing USDC into the Pool
Debit Loan Receivable xx
         Credit Stablecoins
Practically, this shows up as a trade in your crypto subledger because USDC is leaving your wallet, while VAULT is being deposited. These VAULT tokens represent the loan receivable on your books.
Withdrawing Supplied USDC
Debit Stablecoins xx
          Credit Loan Receivable xx
          Credit Interest Income
This methodology treats the difference between the initial USDC supplied and the amount withdrawn as interest income, which is ordinary income per the Internal Revenue Code. The only sticky area here relates to the ability to withdraw (mentioned above). The conservative tax position would be to recognize interest income as youâre earning it, regardless of when youâve actually withdrawn your position.
However, if youâre truly unable to withdraw your entire position because thereâs not enough liquidity, that's a more reasonable defense to claim the income upon withdrawing it (versus when itâs earned). Our discussion on dominion and control above exemplifies that point. If the asset is locked (a great example is locked Solana grants), we typically recognize this income upon unlock, since our customer can only sell it/get funds to pay taxes at this future date.
