Wis. Stat. § 893.87
Any action in favor of the state, if no other limitation is prescribed in this chapter, shall be commenced within 10 years after the cause of action accrues or be barred.

Wis. Stat. § 893.87
This section applies only if the action is of a type that does not fall under any other statute of limitations. State v. Holland Plastics Co., 111 Wis. 2d 497, 331 N.W.2d 320 (1983). When every day of violation of a statute constitutes a separate violation, a cause of action accrues on each day of an alleged violation. State v. Chrysler Outboard Corp., 219 Wis. 2d 130, 580 N.W.2d 203 (1998), 96-1158.
