A number of changes to the state's tax code take effect this week. The changes are part of Michigan's effort to better collect sales and use tax on Internet and catalogue purchases.
Michigan had to change some provisions in its tax code to make it look like other states participating in the national effort. That means some things that had been tax free will ring up with the six percent sales tax beginning Wednesday. Some prescription drugs and contact lenses will be taxed under the new law. Other items, such as deli trays, will no longer be taxed under the changes.
There also are some changes upcoming for filing sales, use, and withholding taxes. Instead of paying those on the 15th of every month, they will be on the 20th.
