A 46-year-old Swansea man is sentenced to one year in the Bristol County jail for tax evasion.   

The District Attorney's Office said Linwood Cowen pleaded guilty to tax evasion and the illegal sale of cigarettes.  Prosecutors said he would but large amounts of cigarettes in New Hampshire and sell them at discounted prices in Massachusetts, avoiding the state tax. 

According to the DA's office Cowen avoided the tax for 18 months, costing the state Department of Revenue about 78-thousand-dollars.
