Wisconsin Payroll Tax Nonpayment Emergency Checklist

Wisconsin Payroll Tax Nonpayment Emergency

Checklist

Introduction

Wisconsin withholding tax nonpayment occurs when an employer fails to remit withheld state income tax to the Wisconsin Department of Revenue by the required deadline. This issue carries significant consequences because withheld employee income taxes must be held in trust and belong to the state, not the employer.

Ignoring nonpayment triggers penalty assessments, interest accumulation at 1.5 percent per month, collection liens, and potential enforcement actions. The sooner you address nonpayment, the more resolution options remain available to you.

What This Issue Means

Withholding tax nonpayment means that withheld employee state income taxes have not been submitted to Wisconsin on time. The Wisconsin Department of Revenue administers two types of payroll tax obligations: Wisconsin income tax withholding and unemployment insurance tax.

Federal payroll taxes, such as federal income tax withholding, Social Security, and Medicare, are separate obligations collected by the IRS, not by Wisconsin. The state tracks these obligations through quarterly reporting and issues notices when payments fall behind the required schedule.

Why the State Issues Notices

Wisconsin requires withholding tax remittance on specific dates to fund state programs and maintain compliance with statutory obligations. When employers fail to submit payments by the deadline, the Department of Revenue sends formal notices to inform them of the shortfall and request immediate action.

What Happens If You Ignore This

Continued nonpayment without action results in mandatory penalty assessments and interest charges on the outstanding balance. The Wisconsin Department of Revenue assesses a delinquent collection fee of 6.5 percent of the amount due or $35, whichever is greater.

Interest accrues monthly at 1.5 percent, which equals 18 percent per year on the unpaid tax balance. Collection efforts may escalate to tax warrants filed with the circuit court clerk, wage attachments requiring your employer to withhold up to 25 percent of gross pay, or bank levies.

What This Does Not Mean

Receiving a Wisconsin withholding tax notice does not automatically mean criminal charges will be filed or that business operations will be shut down immediately. A notice is a formal communication requesting action, not a final enforcement action.

Checklist: What to Do After Receiving a Notice

Step One: Locate and Review All Notices

Find every notice, letter, or document from the Wisconsin Department of Revenue related to withholding tax. Review the notice date, the tax period referenced, and the amount owed. Note any deadline listed on the notice for response or payment. Check your email, physical mail, and

My Tax Account online for additional notices.

Step Two: Verify the Tax Liability

Pull copies of all withholding tax returns filed for the time periods listed in the notice. Compare the amounts reported on your returns to the amounts listed in the state notice.

Step Three: Check Your Payment History

Locate all payment receipts, canceled checks, or electronic payment confirmations. Verify the dates and amounts of every withholding tax payment made to the state.

Step Four: Contact the Department of Revenue

Call the Wisconsin Department of Revenue at the number listed on your notice. Ask to speak with someone in the withholding tax section or the collections division. Provide your notice number, business name, and the tax periods in question. Under Wisconsin Statute 71.91, unpaid taxes automatically become a perfected lien when they are due, and the state may file a tax warrant with the circuit court clerk.

Step Five: Review Your Account Status

Visit the Wisconsin Department of Revenue website and, if available, access My Tax Account.

Review your account balance, payment history, and any filed notices of assessment.

Step Six: Determine Whether You Can Pay in Full

Calculate the total amount owed, including current penalties and interest. Determine whether your business has the cash available to pay the full amount owed immediately. If payment in full is possible, prepare to submit payment using the state's preferred payment method listed on the notice or website. Use a payment method that provides confirmation of receipt, such as ACH payment through My Tax Account, credit card, or certified mail.

Step Seven: Explore Wisconsin DOR Tax Warrant Payment Plan Options

Contact the Wisconsin Department of Revenue to request information about installment payment plans if full payment is not possible. Penalties and interest continue to accrue on unpaid balances during payment plans under Wisconsin law.

Payment plan terms require you to file and pay all future tax returns by their due date. The department charges a $20 fee if you enter into a payment plan.

Step Eight: Address Any Disputes or Errors

Gather documentation to support your claim if you believe the amount owed is incorrect.

Prepare a written summary explaining why you think an error occurred. Wisconsin Statute 71.88 provides that you may petition the department for redetermination within 60 days after receipt of a notice of additional assessment. Contact the Department of Revenue in writing and by phone to request a review.

Step Nine: Document All Communication

Keep a log of every phone call, including the date, time, and person you spoke with. Send follow-up written communication by email or certified mail after phone calls.

Step Ten: Submit Required Information or Payment

Respond to the notice by the deadline listed, even if you cannot pay in full. Submit any documentation requested by the state within the timeframe specified in the notice.

Common Mistakes to Avoid

Never ignore the notice entirely, as penalties and interest accumulate at 1.5 percent per month and collection options narrow over time. Do not miss response deadlines, which are typically 60 days for redetermination petitions under Wisconsin Statute 71.88.

Always request written confirmation that the state has received and credited your payment, rather than assuming it has. Submit complete and accurate information when responding to documentation requests.

Document every communication with the state, every payment made, and every piece of correspondence received. A Wisconsin withholding tax payment plan is only valid if the

Department of Revenue approves it and you comply with all terms, including timely filing and payment of all future returns.
