737.18.28. In computing an eligible individual’s taxable income for a taxation year, there may be deducted an amount for the year equal to the least of (a) the amount determined by the formula
(A − B) × C / 365;
(b) $200,000; and
(c) the amount by which $600,000 exceeds the aggregate of all amounts each of which is an amount deducted by the eligible individual under this section for a preceding taxation year.
In the formula provided for in subparagraph a of the first paragraph, (a) A is the aggregate of all amounts each of which is equal to the eligible individual’s income for the taxation year from the eligible activities of the eligible individual;
(b) B is the aggregate of all amounts each of which is equal to the eligible individual’s loss for the taxation year from the eligible activities of the eligible individual; and
(c) C is the number of days in the taxation year that are in the eligibility period applicable to the eligible activities of the eligible individual.
Where the number of days in a taxation year of the portion of the eligibility period applicable to eligible activities of an eligible individual is less than 365, the amount of $200,000 mentioned in subparagraph b of the first paragraph shall be replaced by the product obtained by multiplying $200,000 by the proportion that that number is of 365.
An amount deductible under the first paragraph in computing an eligible individual’s taxable income for a taxation year shall not be deducted unless the following documents are enclosed with the fiscal return the eligible individual is required to file for the year under section 1000: (a) a copy of the qualification certificate referred to in the definition of “eligible individual” in the first paragraph of section 737.18.27; and
(b) a financial statement relating to the eligible activities of the eligible individual for the taxation year.
