Tax 2.105(4)(a)1.f.

Tax 2.105(4)(a)3.
3. `Agreement with adjustments.'

(b) Amended returns. If a taxpayer files an amended federal tax return and the changes on the amended federal tax return affect the amount of Wisconsin net franchise or income tax or economic development surcharge payable, the amount of a Wisconsin credit or a Wisconsin net operating loss, net business loss or capital loss carried forward, the taxpayer shall file with the department an amended Wisconsin return reflecting the same changes.

If an assessment relates to a federal adjustment that affects a combined report, the department may issue such assessment to either the corporation whose income was adjusted for federal purposes or to the designated agent of the combined group, or both.
Tax 2.105 Note
Note: See s.

Tax 2.105(5)(b)
(b) Refunds. Under s.
71.75 (2), Stats., the department may issue a refund if an amended return is filed within 4 years of the unextended date the original Wisconsin franchise or income tax return was due.
Tax 2.105(5)(c)1.1. An assessment may be made later than the 4- and 6-year periods provided in par.
(a) if notice of the assessment is given to the taxpayer within 90 days of the date the department receives a timely report of federal adjustments or an amended Wisconsin return. However, the assessment made after the expiration of the 4- and 6-year periods shall only relate to those federal adjustments or the changes on the amended Wisconsin return.
Tax 2.105(5)(c)2.
2. If a taxpayer reports federal adjustments to the department after the expiration of the 4-year period for filing an amended Wisconsin return as described in par.
(b), a refund based upon federal adjustments reducing the taxpayer's federal tax liability, which are applicable to the taxpayer's Wisconsin tax or economic development surcharge liability, may still be made if notice of the refund is given to the taxpayer within 90 days of the date the department received a timely report of the federal adjustments.
Tax 2.105(5)(c)3.
3. The 90-day period for the department's giving notice of an assessment or issuing a refund may be extended if a written agreement is entered into by the department and the taxpayer prior to the expiration of the 90 days.
Tax 2.105(5)(c)4.
4. If federal adjustments or changes on an amended return filed with the internal revenue service or another state pertain to a year which has been previously field audited by the department and the field audit has been finalized, an assessment or refund nevertheless may be made. However, the assessment or refund shall only relate to those federal adjustments or the changes on the amended return. Notice of the assessment or refund shall be given to the taxpayer within 90 days of the date the department received the report of federal adjustments or an amended Wisconsin return from the taxpayer.
Tax 2.105 Note
Examples: 1) Federal adjustments were made to an individual's 2013 calendar- year basis federal income tax return; the adjustments became final on June 1, 2018. On August 15, 2018, within 90 days after the adjustments became final, the department received the taxpayer's report of the adjustments. Although the 4-year period provided by s.
71.77 (2), Stats., for making adjustments to the 2013 Wisconsin return expired on April 15, 2018, the department had until November 13, 2018, 90 days after the date the department received a report of the adjustments, to give notice of an assessment to the taxpayer.
Tax 2.105 Note
2) An individual filed an amended 2015 calendar-year basis New York return on June 1, 2016. An amended Wisconsin return, reflecting the changes on the amended New York return, was filed with the department on July 12, 2016. Under the 4-year assessment period in s.
71.77 (2), Stats., the department has 4 years from April 15, 2016, the due date of the 2015 return, in which to notify the taxpayer of any assessment relating to the changes on the amended New York return.
Tax 2.105(6)
(6) Taxpayer's failure to report federal adjustments or file amended Wisconsin return; adjustments and amended returns relating to taxable year 1987 and thereafter. If a taxpayer fails to report federal adjustments or the filing of an amended federal or other state return, relating to the taxable year 1987 and thereafter, within the 90-day period described in sub.
(3) (b), the department may assess additional Wisconsin franchise or income tax or economic development surcharge relating to the adjustments or amended return within 4 years after discovery by the department.
Tax 2.105 Note
Example: An individual taxpayer filed a 2015 calendar-year basis Wisconsin income tax return on April 15, 2016. The internal revenue service made adjustments to the 2015 federal income tax return which the taxpayer did not report to the department within 90 days after the adjustments became final. The internal revenue service reports these adjustments to the department under the exchange of information agreement between the two agencies on May 1, 2018. The department may issue an assessment for the adjustments any time on or before May 1, 2022.
Tax 2.105 Note
Note: Section
71.76, 1989 Stats., was amended by
1991 Wis. Act 39, effective for federal changes or corrections to a federal income tax return that became final on or after August 15, 1991, and for amended federal and other state returns filed on or after August 15, 1991. Under the statute in effect immediately prior to the enactment of
1991 Wis. Act 39, a taxpayer was required to report internal revenue service adjustments to taxable income that affected the income reportable or tax payable to Wisconsin, and to file an amended Wisconsin return if information contained on an amended federal or other state tax return affected income reportable or tax payable to Wisconsin.
