North Dakota tax officials expect a record number of returns to be filed in 2013. In 2012 nearly 410-thousand tax forms were processed by the North Dakota Tax Department -- an increase of 33-thousand compared to 2011. Tax Commissioner Cory Fong says he wouldn’t want to make a prediction how high the number will climb this year. The department mailed out 65-thousand tax books last week. Nearly 81-percent of taxpayers filed electronically in 2012. Fong says you won’t see any major changes on this year's forms but with a legislative session just around the corner you can expect some tweaking for the 2013 tax year to be filed in 2014.
