For the first time since the enactment of the False Claims Amendment Act of 2020, the DC Attorney General’s (AG’s) Office has used its new tax enforcement powers to pursue an alleged personal income tax deficiency. This development brings to the forefront a long-simmering constitutional problem with DC’s statutory residency law and offers a stern warning to businesses that assist key employees and executives with their personal tax obligations.

The press rapidly and widely reported on DC’s lawsuit against MicroStrategy Co-Founder, Executive Chairman and former CEO Michael Saylor for alleged evasion of D.C. personal income taxes, which was made public this week. The case alleges that Saylor wrongly claimed that he was a resident of Virginia or Florida (rather than DC) since at least 2012.

The case was originally brought under seal by a relator under DC’s False Claims Act in April 2021—less than one month after the False Claims Amendment Act took effect. Using its new tax authority, the DC AG’s Office filed a complaint last week to intervene (taking over the case going forward). Interestingly, when the DC AG’s Office took over the case, it added MicroStrategy as a defendant under the theory that the company conspired to help Saylor evade DC personal income taxes. Under DC’s False Claims Act, both Saylor and MicroStrategy could be liable for treble damages if a court rules in favor of the DC AG’s Office.

ISSUES WITH DC’S “STATUTORY RESIDENCY” TEST

While determining where an individual is a resident for state and local tax purposes generally requires a fact-intensive analysis, the case against Saylor also implicates DC’s unique (and likely unconstitutional) statutory residency standard. DC’s statute is fundamentally different than statutory residency standards in other states. Most states only tax individuals having their domicile in the state as residents, while some states also have a “statutory residency” test to classify individuals as taxable residents. In most states, a person is classified as a statutory resident if they (1) maintain a permanent place of abode in the jurisdiction and (2) spend more than a specific number of days (typically 183 days) in the jurisdiction.

DC truncates this standard and classifies someone as a statutory resident if they merely maintain a personal place of abode in DC for more than 183 days. Thus, no amount of actual presence of the individual in DC is required. The problem created by this one-of-a-kind standard should be obvious: someone can (as many high-net-worth individuals often do) maintain a residence for 183 days in more than one jurisdiction. Thus, the plain language of the statute would violate the Commerce Clause of the US Constitution because it runs afoul of the internal consistency test. Under this test, a statute is unconstitutional if under a hypothetical situation in which every jurisdiction has the same law as the one being challenged, more than 100% of the tax base would be subject to tax. Here, if every state had a statutory residency test applicable to anyone who had a [...]
