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

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.

(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.
