Line 13a – Circulation expenditures
If you elected the optional 3-year write-off period for circulation expenditures under IRC Section 59(e), skip this line.
For regular tax, IRC Section 173 allows you to deduct the full amount of circulation expenditures in the taxable year you paid or incurred them. For AMT, you must amortize these expenditures over three years beginning with the year you paid or incurred the expenditures. Enter the difference between your AMT deduction and your regular tax deduction. If your AMT deduction is more than your regular tax deduction, enter your adjustment as a negative amount.
See IRC Section 56(b)(2) for a special rule that applies to losses related to circulation expenditures.
