With the new tax rates effective for the 2022 tax year, how do I estimate my income tax liability in order to make estimated payments?

The instructions posted for the Declaration of Estimated Tax for Individuals has a worksheet that should be used to calculate your estimated tax liability. Form IT-540ESi will be posted on LDR’s website on January 18, 2022. Remember not to reduce your estimated taxable income by your estimated federal income tax liability.
