Capital Construction Fund
Do not claim on Schedule C the deduction for amounts contributed to a capital construction fund set up under chapter 535 of title 46 of the United States Code. Instead, reduce the amount you would otherwise enter on Form 1040 or 1040-SR, line 15, by the amount of the deduction. Next to line 15, enter “CCF” and the amount of the deduction. For details, see Pub. 595 .
