Form Sources:
Wisconsin usually releases forms for the current tax year between January and April. We last updated Wisconsin Schedule U from the Department of Revenue in January 2022.
Schedule U is a Wisconsin Individual Income Tax form. While most taxpayers have income taxes automatically withheld every pay period by their employer, taxpayers who earn money that is not subject to withholding (such as self employed income, investment returns, etc) are often required to make estimated tax payments on a quarterly basis. Failure to make correct estimated payments can result in interest or penalties.
About the Individual Income Tax
The IRS and most states collect a personal income tax, which is paid throughout the year via tax withholding or estimated income tax payments.
Most taxpayers are required to file a yearly income tax return in April to both the Internal Revenue Service and their state's revenue department, which will result in either a tax refund of excess withheld income or a tax payment if the withholding does not cover the taxpayer's entire liability. Every taxpayer's situation is different - please consult a CPA or licensed tax preparer to ensure that you are filing the correct tax forms!
