Adjustment of credits.
Except as provided in sub. (9), for the purpose of adjusting credits, the department may do all of the following:
(a)#
Assess an adjustment to reduce a credit under s. 71.07, 71.28, or 71.47 to a pass-through entity if the pass-through entity previously computed the credit and reported the credit to its pass-through members. An assessment made under this paragraph may be reduced by the tax effect from the modifications described under ss. 71.05 (6) (a) 15. and 25., 71.21 (4), 71.26 (2) (a) 4. and 11., 71.34 (1k) (g) and (m), and 71.45 (2) (a) 10. and 10a., if the modification occurs in a taxable year under review, except that the modification shall not pass through to nor be claimed by the pass-through members.
(b)#
Assess an adjustment to increase a credit under s. 71.07, 71.28, or 71.47 to offset additional tax assessed to a pass-through entity under sub. (2). Any excess credit not used to offset additional tax may be claimed by the pass-through members within one year from the date the determination of the adjustment becomes final or before the end of the period specified under s. 71.75, whichever is later.
