The penalties provided under this subdivision shall be assessed, levied, and collected in the same manner as income or franchise taxes. 7. ‘Failure to keep records required by the department.’ Any taxes assessed upon information not contained in records required by the department under s. 71.80 (9) to be kept by any person subject to an income or franchise tax shall carry a penalty of 25 percent of the amount of the tax.

X shall be subject to a penalty equal to the difference between the amount required to be withheld and the amount actually withheld for the period that the incorrect certificate, form or agreement was in effect. 5. ‘Joint return after separate returns.’ If the amount shown as the tax by the husband and wife on a joint return filed under s. 71.03 (2) (g) to (L) exceeds the sum of the amounts shown as the tax on the separate return of each spouse and if any part of that excess is attributable to fraud with intent to evade tax at the time of the filing of that separate return, then 50 percent of the total amount of that excess shall be added to the tax. 6. ‘Corporations.’ If a corporation or limited liability company files a false declaration of complete inactivity, or, after filing a declaration, becomes activated or reactivated and fails to file timely statements and information under this chapter covering such year or years of activity or reactivity its officers or managers at the time of such filing or failure shall be jointly and severally liable for a civil penalty of $25 for such filing or each such failure, which penalty may be assessed and collected as income or franchise taxes are assessed and collected. 7. ‘Fraudulently filed claims.’ A person who fraudulently files an incorrect claim for refund of tax, or credits, under this chapter is subject to a penalty of 100 percent of the difference between the amount claimed and the amount that should have been claimed.

The penalty described under subd. 1. shall be the amount of income tax that would have been imposed under s. 71.02 on the capital gains received by the transferor in the transaction described in subd. 1. if the exemption under s. 71.05 (6) (b) 25. did not apply to the transaction multiplied by a fraction, the denominator of which is 24 and the numerator of which is the difference between 24 and the number of months between the date on which the person who is liable for the penalty purchased or otherwise received the assets described in subd. 1. and the month in which the person sells or otherwise disposes of the assets. 3. The department of revenue shall assess, levy and collect the penalty under this paragraph as it assesses, levies and collects taxes under this chapter.
