The amount of time Maryland prosecutors would have to file charges against people who commit tax crimes would double under a bill being pushed by Comptroller Peter Franchot.

Franchot announced Tuesday that he is proposing that the state extend the statute of limitations for tax crimes from three years to six years.

The comptroller said the state needs “sufficient time” to investigate and charge offenders in what are often “highly sophisticated schemes.”

“Passage of this act will allow my agency to keep pace with rapidly increasing fraud schemes and fast-changing threats to sensitive data,” Franchot said in a statement.

The additional time to prosecute tax offenders is the main thrust of Franchot’s proposal. But the bill also includes a provision that would make certain major criminal tax offenses a felony and allow injunctions to be issued against tax preparers who are under investigation.
