New York · NY DTF · Used for tax years 2025
New York Form CT-222.1 lets a corporation elect one of two alternative annualization periods to calculate estimated tax under the annualized income installment method. It identifies the applicable returns, tax period, and selected option.
Who files this form
A corporation using the annualized income installment method to calculate estimated tax may file Form CT-222.1 to elect option 1 or option 2.
File the form each year you choose either option, even if you choose the same option every year. If you use the standard option, do not file Form CT-222.1.

Common mistakes
- Filing when using the standard option. The instructions say not to file Form CT-222.1 for the standard option.
- Assuming last year’s election carries over. You must file annually, even if you choose the same option.
- Combining returns with different election due dates. If the due dates differ, file a separate Form CT-222.1.
- Leaving out the tax period. All filers must enter the beginning and ending dates.
- Forgetting the signature. Failure to sign will delay processing of any refunds and may result in penalties.
- Leaving paid preparer entries incomplete. If an outside individual or firm prepared the election, all applicable entries, including identification numbers, must be completed.
