How to Report Ethereum Gas Fees on Your Tax Return in 2024

Ethereum gas fees are crucial for executing transactions on the Ethereum blockchain. They compensate validators and maintain the network's security and efficiency. As the Ethereum protocol evolves, particularly with scalability improvements and adjustments in fee structures, understanding these fees becomes vital for anyone interacting with the network.

Ethereum gas fees are payments made by users to compensate for the computational energy required to execute and validate transactions on the Ethereum network. These fees are denoted in gwei, which is a smaller denomination of ETH.

Gas fees are an incentive for miners to prioritize and validate transactions, which is foundational for the network’s operational efficiency.

Gas fees help regulate the network’s computational demand by preventing spam transactions and efficiently allocating resources. This mechanism also establishes a competitive market for transaction processing, where users can pay higher fees for priority processing, especially beneficial during high network congestion periods.

The Ethereum network has seen significant updates aimed at making gas fees more predictable and fair for users, especially with the London upgrade and the introduction of EIP-1559.

Impact of EIP-1559

EIP-1559, a major component of the London upgrade, introduced a dual fee structure consisting of a base fee and a priority fee (tip). The base fee is algorithmically adjusted and burned, reducing ETH supply and potentially leading to deflationary pressure on Ethereum. This update aims to alleviate some of the unpredictability associated with gas fees and improve transaction cost estimates.

Benefits of the new Ethereum fee system

The new fee structure benefits users by smoothing fee volatility and improving transaction inclusion reliability. Burning the base fee aligns the interests of miners and users toward network efficiency, potentially making fee market economics more stable and predictable.

Gas fees are a significant consideration for Ethereum users, as they directly impact the cost-effectiveness of transactions on the network.

Cost implications of Ethereum network congestion

During periods of high demand, such as popular token launches or NFT drops, gas fees can escalate quickly, making even simple transactions expensive. This variability emphasizes the importance of understanding and strategically interacting with the network to minimize costs.

Strategies to manage crypto transaction fees

Users can manage their transaction costs by scheduling transactions during less busy times or utilizing Ethereum’s second-layer solutions, which offer lower fees. Adjusting gas price settings in Ethereum wallets also allows users to effectively balance transaction urgency with cost considerations.

The tax treatment of Ethereum gas fees can influence financial planning and tax obligations for cryptocurrency users. Ethereum gas fees may be tax deductible, depending on if the gas fee was part of a crypto transaction for personal or professional use. Gas fees can also be used to adjust cost basis.

Reporting Ethereum gas fees on tax returns

In jurisdictions like the US, Ethereum gas fees are included in the cost basis of transactions for tax purposes. This treatment can affect the calculation of capital gains or losses when cryptocurrencies are sold, exchanged, or spent.

US taxpayers report crypto gas fees on Form 8949, along with their cost basis, gross proceeds, and the dates the crypto was received and disposed.

How gas fees reduce taxable gains

By increasing the cost basis of a cryptocurrency transaction, gas fees reduce the capital gain—or increase the capital loss—reported on tax returns. This can lead to lower tax liabilities, making accurate tracking and reporting of these fees crucial for tax compliance.

Are crypto gas fees tax deductible? We recommend treating them conservatively because the IRS has not issued specific guidance on crypto gas fees. However, based on existing guidance it is likely the tax treatment of gas fees depends on the type of crypto transaction they were related to - namely, personal or professional.

The question " Are gas fees tax deductible?" is nuanced, and tax laws regarding cryptocurrency are evolving. We strongly recommend speaking with a qualified crypto tax accountant who can provide guidance based on your circumstances.

Whether crypto gas fees are deductible depends on the nature of your crypto activity

If you use crypto such as Ethereum for personal investments, your corresponding crypto gas fees are unlikely to be considered tax-deductible expenses. However, the fees can be used to adjust your cost basis, which we cover further in this article.

If you use crypto for business activities or trade professionally, you may be able to deduct crypto gas fees as a business expense. This might apply if you actively mine, trade, or conduct other business with cryptocurrency or accept crypto as a form of payment.

How to handle crypto gas fees for trade transactions

Using Ethereum or other cryptocurrency for gas fees may trigger a taxable event, typically in the event of a sale. The IRS may treat this use of crypto for gas as if you sold a capital asset. This means you may need to report capital gains or losses from your trades.

In other words, if the cryptocurrency you use to execute a trade has appreciated in value since you acquired it, you must report that disposal and corresponding capital gains to the IRS using Form 8949, along with your gross proceeds, cost basis, and the date you received and disposed of your cryptocurrency.

When selling, crypto gas fees can also reduce your proceeds, reducing capital gains. In the case of purchases, the gas fees can be added to the cost basis of the purchase.

How to handle crypto gas fees for transactions that aren’t trades

The IRS has not provided guidelines as per the treatment of transfers between wallets and transactions involving gas fees that are not linked to acquiring or disposing of assets. Typically, the IRS permits expenses to be applied to the cost basis of property if the transaction satisfies either of the following:

• It is essential in order to purchase or sell the property.

• It enhances the property’s intrinsic value.

With an aggressive approach, crypto gas fees expended to manage investments would augment the basis of the same crypto assets utilized for gas. This applies when you use crypto gas fees to transfer crypto between wallets to gain access to different crypto assets or DeFi protocols. With this approach, the cost basis of your ETH can be increased by the gas fees.

We recommend taking the conservative approach of treating crypto gas fees that are not related to asset acquisition or disposal as nondeductible.

Here are instructions for taxpayers to report crypto gas fees on their tax returns. How you report will be determined by whether you use crypto personally or professionally, and your region.

• Determine the purpose of your crypto activities: Do you use crypto for personal investment or business purposes? This will likely impact how you report the gas fees.

• Personal investment: If you use crypto for personal reasons, gas fees are not typically tax-deductible. You would report your capital gains or losses from buying, selling, or exchanging crypto (such as Ethereum) on your tax return as per your region’s regulations.

• Business activities: If you engage in crypto-related business activities (such as mining, trading, or operating a business that accepts crypto), you may be able to deduct corresponding crypto gas fees as a business expense.

• Record your gas fees: Maintain comprehensive records of your crypto transactions, including the gas fees paid. You can find this information on a blockchain explorer and, in most cases, in your crypto wallet's transaction history.

• Reporting gas fees: Depending on the tax laws in your region, you may report gas fees as part of your business expenses on the appropriate tax forms. This could be Schedule C (in the United States) for self-employed taxpayers or a similar form for reporting business income and expenses.

When you spend crypto such as Ethereum for gas fees, this may trigger a taxable event. In the case of gas for disposals of crypto assets, the IRS treats this as if you sold a capital asset (that is, the crypto used for the sale). This means you may need to report capital gains or losses resulting from certain gas fee transactions.

Gas fees in cryptocurrency transactions are not only subject to taxation but can also reduce your capital gains when buying or selling digital assets.

• Buying Assets: When you purchase digital assets such as cryptocurrencies, associated costs like gas fees can be added to the cost basis. Doing so effectively reduces the capital gain you might incur when you sell or dispose of the asset. In other words, incorporating these costs into your investment helps minimize your potential tax liability and means purchases are generally not taxable events.

• Selling or Trading Assets: When you sell, trade, or dispose of crypto, this typically triggers a taxable event. Expenses related to these transactions, such as crypto gas or exchange fees, can be deducted from the proceeds. By doing so, you are able to reduce your taxable gains and optimize your tax situation.

When you claim yield farming rewards (e.g. CRV from Curve), airdrops (e.g. UNI from Uniswap), or staking rewards (e.g. SNX and sUSD from Synthetix), the crypto received is taxed as income.

When crypto is received as income, your cost basis is the market value. However, you can include gas fees in your cost basis calculation so that you have lower capital gains or higher capital losses when you sell these assets.
