New York State (and Federal) estimated tax payments for the first quarter of 2022 were due on Monday, April 18, 2022 because the traditional Tax Day of April 15 was Good Friday.
In the federal interview I entered my state and federal estimated payments with the date of April 18. On the New York underpayment penalty form 2105.9 this throws my first quarter payment into the second quarter because the forms says the payments was due on April 15 (payment vouchers clearly say April 18). The federal form 2210 was done correctly.
