Filing requirements for a qualified subchapter S subsidiary that is owned by a New York S corporation, a New York C corporation, or a nontaxpayer corporation:
- Parent is a New York S corporation: New York State will follow the federal qualified subchapter S subsidiary treatment. This includes a parent that is mandated to file as an S corporation under Tax Law § 660(i)).
- The parent and subsidiary will be taxed as a single New York S corporation under Article 9-A (and the shareholders of the parent will be taxed under the Article 22 personal income tax).
- This treatment will apply whether or not the subsidiary, viewed on a stand-alone basis, is a New York taxpayer.
- The parent (with its qualified subchapter S subsidiary’s activity included) files as a New York S corporation on a Form CT-3-S, New York S Corporation Franchise Tax Return.
- Parent is a New York C corporation: New York will follow the federal qualified subchapter S subsidiary treatment if:
- the subsidiary is a New York taxpayer, or
- the subsidiary is not a taxpayer but the parent makes a qualified subchapter S subsidiary inclusion election.
In both instances, the parent and the subsidiary will be taxed as a single New York C corporation (and the shareholders of the parent will be treated as shareholders of a C corporation). The parent (with its qualified subchapter S subsidiary’s activity included) files as a New York C corporation on a Form CT-3, General Business Corporation Franchise Tax Return.
If the subsidiary is not a taxpayer and the parent does not make a qualified subchapter S subsidiary inclusion election, the parent will file as a New York C corporation on a stand-alone basis.
- Nontaxpayer parent: New York State follows the federal qualified subchapter S subsidiary treatment where the qualified subchapter S subsidiary is a New York State taxpayer but the parent is not, if the parent elects to be taxed as a New York S corporation by filing Form CT-6, Election by a Federal S Corporation to be Treated As a New York S Corporation. The parent and qualified subchapter S subsidiary are taxed as a single New York S corporation, and file Form CT-3-S.
If the parent does not elect to be a New York S corporation, the qualified subchapter S subsidiary (without its parent’s activity included) must file as a New York C corporation on a Form CT-3 or, if the combined filing requirements are met with one or more other entities (one of which could be the parent), on a Form CT-3-A. In this case, both the parent and the qualified subchapter S subsidiary, as separate entities, are subject to the combined reporting rules, and if the parent and qualified subchapter S subsidiary are unitary they both file as distinct members of a combined group on the same Form CT-3-A.
- Exception: excluded corporation: Notwithstanding the above rules, qualified subchapter S subsidiary treatment is not allowed when the parent and qualified subchapter S subsidiary file under different Articles of the Tax Law (or would file under different Articles if both were subject to New York State franchise tax). In this case, each corporation must file as a distinct entity under its applicable Article, subject to the Article 9-A or Article 33 combined reporting rules, as applicable.
