Income tax withholding reporting and payment rules by state

Employers in states with an income tax have state payroll tax withholding obligations. Multi-state employment withholding may be governed by reciprocal agreements between states.
For the states imposing a personal income tax, the information includes:

• A general statement about your obligation to withhold the state's tax from wages you pay to resident and nonresident employees
• Links to downloadable copies of the federal Form W-4 and the state's equivalent withholding exemption certificate, if available
• A listing of the other states, if any, with which the selected state has entered reciprocal agreements
• The contact information for the agency that administers the state's withholding tax
• A listing of the local jurisdictions, if any, where you may have a withholding or payment obligation if you have employees

For a detailed summary about income tax as it relates to withholding payroll tax, we have the following article: Understanding Payroll Tax Payment and Filing Requirements
