(1) In the case where an incomplete return is made, notwithstanding that no tax is finally determined to be due for the taxable year, there shall be added to the amount of tax, penalty, and interest otherwise due a penalty in the amount of $300 or 10 percent of the tax finally determined to be due, whichever is greater; however, such penalty shall not exceed $10,000. The department may settle or compromise such penalties pursuant to s. 213.21. (2) An “incomplete return” is, for the purposes of this code, a return which is lacking such uniformity, completeness, and arrangement that physical handling, verification, or review of the return may not be readily accomplished.
