The 2020 New York State and Yonkers withholding tax tables have been updated.  There were no updates required for New York City at the time of this bulletin issuance.

The value of one New York State, New York City and Yonkers withholding allowance remains at $1,000.

Additional Withholding Adjustment for Nonresident Aliens
The withholding of federal income tax on the wages of nonresident alien employees is subject to an additional withholding amount that is added to nonresident alien employees’ wages for calculating Federal income tax.  The additional withholding amount added to annual income has increased to $8,100 for 2020 if the NRA employee was first paid wages before 2020 and has not submitted a new Form W-4 for 2020 or later.  If the NRA employee was first paid wages in 2020 or later or has submitted a new Form W-4 for 2020 or later, then the additional withholding amount added to annual income is $12,400.  This procedure does not apply to nonresident alien students from India.
