  • NYC-ATT-S-CORP - Calculation of Federal Taxable Income For S Corporations

    Please note: We have received questions about how to fill out lines 4b and 17 of Form NYC-ATT-S-CORP. If you are not subject to IRC section 163(j), add back your interest deduction on line 4b and then deduct that amount on line 17. If you are subject to IRC section 163(j), add back the interest deduction on line 4b, and complete IRS Form 8990 (as if your S-corp were actually a C-corp) to calculate your business interest deduction. Enter the amount from line 30 of Form 8990 on line 17 of Form NYC-ATT-S-Corp. See the Form NYC-ATT-S-CORP instructions for more detail.
