Wisconsin Employer's Withholding Tax Guide Revised

The Wisconsin Employer's Withholding Tax Guide (Publication W-166) has been updated. The withholding tables and alternate methods of withholding (A and B) have been revised due to the new top individual income tax rate of 7.75% and bracket adjustment resulting from inflation.

The revised withholding tables or alternate methods should be implemented no later than October 1, 2009.
