Common confusion points
Do I need to report de minimis extraordinary items on line 15?
The worksheet distinguishes line 15 from line 22b for extraordinary items.
→ Confirm that de minimis items are only on line 22b, not line 15.

The form has separate parts for each method and instructions on which parts to complete.
→ Check which parts (II, III, IV) you filled based on the method chosen.
Can I claim tax withheld in a later installment period?
The instructions allow claiming payments or withholding learned later in a subsequent period.
→ Verify that the amount is entered in the column of the period you are claiming.
What types of income qualify for preferential rates on lines 1i, 1m, 1q?
Lines reference specific sections and Schedule D lines for 28% gain, unrecaptured §1250 gain, and adjusted net capital gain.
