Surety bond; nonresident contractor.

All nonresident persons, whether incorporated or not, engaging in construction contracting in this state as contractor or subcontractor and not otherwise regularly engaged in business in this state, shall file a surety bond with the department, payable to the department of revenue, to guarantee the payment of income or franchise taxes, required unemployment insurance contributions, sales and use taxes and income taxes withheld from wages of employees, together with any penalties and interest thereon. The department shall approve the form and contents of such bond. The amount of the bond shall be 3 percent of the contract or subcontract price on all contracts of $50,000 or more or 3 percent of contractor’s or subcontractor’s estimated cost-and-profit under a cost-plus contract of $50,000 or more. When the aggregate of 2 or more contracts in one calendar year is $50,000 or more the amount of the bond or bonds shall be 3 percent of the aggregate amount of such contracts. Such surety bond must be filed within 60 days after construction is begun in this state by any such contractor or subcontractor on any contract the price of which is $50,000 or more (or the estimated cost-and-profit of which is $50,000 or more), or within 60 days after construction is begun in this state on any contract for less than $50,000, when the amount of such contract, when aggregated with any other contracts, construction on which was begun in this state in the same calendar year, equals or exceeds $50,000. If the department concludes that no bond is necessary to protect the tax revenues of the state, including contributions under ch. 108, the requirements under this subsection may be waived by the secretary of revenue or the secretary’s designated departmental representative. The bond shall remain in force until the liability thereunder is released by the secretary or the secretary’s designated departmental representative.
