If you know you have an old bitcoin or dogecoin account somewhere but haven’t gotten around the digging up your login information, you may have a nasty surprise waiting for you. With the rise of cryptocurrency, nine states have now adopted rules that include it as a form of unclaimed property and several more are requiring or recommending that companies report their unclaimed virtual currency.

That means that this fall, when banks, insurers, retailers and state government agencies are required to annually report and remit any unclaimed funds, your old cryptocurrency account could be liquidated and turned in to the state’s unclaimed property office.

There are a lot of concerns about this possibility, not the least of which is the fact that liquidating a cryptocurrency account prevents the owner from realizing any future gains. But there’s also a larger economic issue, says Kristine Butterbaugh a solution principal, at the tax firm Sovos.

“Some of our clients don’t want to liquidate these accounts because it could have an impact on the market as a whole,” she says. “We’re talking millions of accounts, potentially, across the country.”

What’s muddling things is a lack of clarity on the rules around cryptocurrency. Unclaimed property law is written for traditional property but now it’s being enforced for non-traditional property.

Here’s how unclaimed property law usually works: Every fall, businesses are required to remit any unclaimed property to the state. For accounts and other financial instruments to be considered unclaimed, they have to be dormant for three to five years, depending on the state. That means the account holder hasn’t accessed the account or responded to any communications. Once the account is deemed unclaimed, it gets transferred to the state’s general fund.

That’s all well and good when we’re talking about a traditional bank account that is sitting around earning minimal — if any — interest. But states aren’t equipped to hold cryptocurrency, so they’re telling firms to turn those accounts into cash before handing them over.

Now let’s say you watched the meteoric rise of dogecoin this past spring and decided to go hunting for those coins you invested in on a whim a few years ago. And when you finally tracked them down you discovered your account was liquidated back in November, robbing you of thousands of dollars in potential earnings? You’d probably be pretty angry.

“Companies are in a really uncomfortable position because they’re unsure whether or not they should be liquidating for fear of owner retribution down the road,” says Butterbaugh. “And then you have the state saying, ‘You have to,’ even if it’s not explicitly in the statute.”

States are also motivated to enforce unclaimed property laws because it’s a revenue gain for them. Although the state keeps track of the amount due and the rightful owner can still eventually claim the money at any time, states in the meantime can use the money for their general operations. This may seem like a gamble, but only about 2% of unclaimed property ever gets returned to the true owner, according to Accounting Today.

Delaware — home to more than a million companies — is one of the most aggressive states when it comes to auditing companies on unclaimed property law compliance and has secured hundreds of millions of dollars over the last decade in unclaimed property and fines.

So, companies are stuck between not wanting to get dinged for noncompliance and being afraid to liquidate a cryptocurrency account. They want more clarity on what to do and Butterbaugh says two places — New York and Washington, D.C. — are working on a solution.

But in the meantime, she advises companies dealing in cryptocurrency to start addressing their dormant accounts now.
