First, Taonsa beat MFF centre-back Stian Gregersen and calmly made it 1-0 in the 14th minute.
Seven minutes into the second half, the Västerås striker extended the lead when he ran through and made it 2-0 with a finish that did not look entirely unstoppable for former national team goalkeeper Robin Olsen.
The victory means Västerås, with 35 points, is now fourth in the table and has moved ahead of, among others, Malmö, which has 33 points.
At the same time, IFK Göteborg won 1-0 away to Brommapojkarna after Alexander Simmelhack scored the only goal of the match at Grimsta.
