Ethereum Merge and the hefty tax bill you could be in for

Ethereum (ETH) hodlers that don’t play their cards right following the Ethereum Merge may be in for a hefty bill come tax time, according to tax experts. 

Around Sept.15, the Ethereum blockchain is set to transition from its current proof-of-work (PoW) consensus mechanism to proof-of-stake (PoS), aimed at improving the network’s impact on the environment.

There is a chance that The Merge will result in a contentious hard fork, which will cause ETH holders to receive duplicate units of hard-forked Ethereum tokens, similar to what happened when the Ethereum and Ethereum Classic hard fork occurred in 2016. 

Tax compliance firm TaxBit Head of Government Solutions, Miles Fuller told Cointelegraph the Merge raises some interesting tax implications in the case that a hard fork occurs, stating:

The biggest question for tax purposes is whether the Merge will result in a chain-splitting hard fork.

“If it doesn’t, then there are really no tax implications,” explained Fuller, noting that the current PoW ETH will just become the new PoS ETH “and everyone goes on their merry way.”

However, should a hard fork occur, meaning ETH holders are sent duplicate PoW tokens, then a “variety of tax impacts may fall out “depending on how well supported the PoW ETH chain is” and where the ETH is held when the fork occurs. 

For ETH held in user-owned on-chain wallets, Fuller points to IRS guidance stating that any new PoW ETH tokens would be regarded as income, and will be valued at the time the user came in possession of the tokens. 

Fuller explained the situation may be different for ETH held in custodial wallets, such as exchanges, depending on whether the platform decides to support the forked PoW ETH chain, noting:

“How custodians and exchanges handle forks is generally covered in your account agreement, so if you are not sure, you should read up.”

“If the custodian or exchange does not support the forked chain, then you likely don’t have any income (and may have missed out on a freebie). You can avoid this by moving your holdings to an unhosted wallet pre-Merge to ensure you get any coins (or tokens) resulting from a possible chain-splitting fork,” he explained.

The performance of the PoW token can also impact the potential tax bill, according to an Aug. 31 Twitter post from CoinLedger Director of Strategy Miles Brooks.

“If the value of the tokens goes down severely subsequent to the PoW fork (and after you have control over them) — which could be likely —…
