Product Title: 2020 Form CT-1040NR/PY, Connecticut Nonresident and Part-Year Resident Income Tax Return Instructions

Revision Date: April 15, 2021

2020 Form CT-1040NR/PY Instructions, Page 24, Schedule 2 – Credit for Income Taxes Paid to Qualifying Jurisdictions; Income Derived From or Connecticut With Sources Within a Qualifying Jurisdiction, second bullet is replaced to read as follows:

For taxable year 2020 only, compensation received for personal services rendered while working remotely from Connecticut if another qualifying jurisdiction imposed tax on such compensation. These employees should retain documentation detailing their specific facts and circumstances for 2020. This documentation should not be submitted with the employee’s return.

Page 31, Employee Apportionment Worksheet Instructions; Who May Not Apportion Income is updated to read as follows:

New for Tax Year 2020 - A nonresident employee’s compensation for personal services rendered while working remotely from outside of Connecticut is not considered Connecticut-sourced income, regardless of the employee’s state of residence. See Taxpayer Services Special Bulletin (TSSB) 2021-1, Taxpayer Services Division Update to Commissioner’s Bulletin of March 4, 2021. A nonresident employee may have received a 2020 Form W-2 from their employer sourcing such compensation to Connecticut, and Connecticut income tax may have been withheld.

Connecticut will not require employers to issue a corrected Form W-2 in this situation. Affected employees who do not receive a corrected Form W-2 should apportion their income using the Employee Apportionment Worksheet. Enter the amount of Connecticut income tax withheld, as reported on Form W-2, on Form CT-1040NR/PY, Line 20. These employees should retain documentation detailing specific facts and circumstances for 2020. This documentation should not be submitted with the employee’s return.
