Form4466W: Wisconsin Corporation or Pass-Through Entity Application for Quick Refund of Overpayment of Estimated Tax (2024)
Wisconsin · Wisconsin DOR · Used for tax years 2024
Wisconsin Form 4466W is an application for a quick refund of estimated tax overpaid by a corporation or pass-through entity. It reports estimated payments, prior-year overpayment credits, expected tax liability, and the overpayment requested for refund.
Who files this form
Form 4466W is an application for a quick refund, not a required filing for every business. A corporation or pass-through entity may apply if its estimated tax overpayment is both:
- At least 10% of its expected tax liability.
- At least $500.
Pass-through entities may apply only for overpayments relating to their pass-through withholding tax liability. Estimated payments relating to the economic development surcharge are not eligible for a quick refund.
When it's due
For tax year 2024, file Form 4466W after the end of the taxable year and before the corporation or pass-through entity files its tax return. The text does not give a specific calendar filing date.
What you'll need
Have the following information ready to complete the application:
- The entity’s name, address, identifying number, state and year of incorporation or organization, and tax account numbers requested on the form.
- The calendar year or taxable year beginning and ending dates, and when the tax return will be filed.
- Estimated tax payments for the taxable year and any prior-year overpayment allowed as a credit.
- Gross tax and any surcharge, or total withholding tax, computed from the return to be filed.
- Credits other than estimated tax credits.
The form includes an authorized signer’s signature, title and date, plus preparer signature and contact fields.
