Compound tax reporting for Belgians
Cryptotax automatically recognises your Compound interest, loans, liquidations and collateral swaps. Ideal for investors who want to know how to correctly report "Compound interest" and "crypto loans in Belgium".
Start free scanWhat is Compound?
Compound is a DeFi protocol on Ethereum where you can deposit (supply) crypto assets to earn interest or borrow against collateral. The smart contracts automatically handle interest payments in the form of cTokens and adjust collateral ratios in real time. Belgian users often search for "reporting interest from Compound lending" because the tax treatment can seem complex.
Interest via cTokens
When you deposit ETH, USDC or other assets, you receive cTokens that increase in value. That increase is the interest we include in your report as movable income.
Loans and collateral
You can borrow against your collateral without selling it. The loan itself is not a taxable event, but we do track which assets serve as collateral and when repayments occur.
Liquidations and swaps
When the collateral ratio falls too low, a liquidation or collateral swap can occur. Cryptotax detects these events so you can report them correctly.
What does Cryptotax support for Compound?
We import on-chain data directly from Ethereum and match it against Compound smart contracts, allowing us to handle every important scenario for Belgian investors.
Interest tracking
cToken accumulation and distributions are recorded as interest income, including historical prices for your fiscal year.
Loans and repayments
Borrow events, repayments and additional collateral are registered chronologically so you keep a clear overview of outstanding debts.
Liquidations & collateral swaps
We detect partial and full liquidations, health-factor warnings and collateral swaps to correctly calculate capital losses or gains.
Transparent reports
You receive a Belgian report with clear sections for movable income, miscellaneous income and any private capital gains.
How does the Belgian tax authority treat Compound transactions?
Our tax engine follows the guidelines for Belgian individuals and self-employed persons. Below you will find the most common scenarios.
Interest on deposits (supply)
The increase in value of your cTokens is treated as movable income. Cryptotax calculates the EUR value at the moment of attribution and places it in the correct section of your tax return.
Taking out a loan
Taking out a loan (borrow) is not in itself a taxable event as long as your collateral is not sold. We do register it so that repayments can be correctly attributed.
Liquidations
In a liquidation, part of your collateral is sold. That is a taxable transaction: we calculate capital gains or losses using FIFO/LIFO and account for any fees.
Collateral swaps
When you switch collateral between assets, we treat this as an exchange transaction. The realised results appear automatically in your report.
Repayments and interest costs
Interest paid on loans can in some cases be recorded as a cost for professional users. Our reports show the exact amounts and timing.
