I hire someone for my taxes. But my situation is a bit different. Both me and my wife work, child care deduction, own a home, inheritance (both cash from life insurance, and a home/property), plus I worked in 3 different states. But at least it was all for one company.
My most expensive year, I lived in Iowa, and had the following work stuff happen
Iowa based company, work done in Iowa
Iowa based company, work done in Illinois
Missouri based company, work done in Iowa
Iowa based company, work done in Nebraska
My dad used to do the same thing and worked for 14 different contractors in one year, I think by record is 7 or 8 including unemployment.
