This webinar discusses the handling of state taxes, wage and hour law, and garnishments when an employee lives in one state and works in another or works in two or more states simultaneously.  Includes determining liability as an employer, reciprocal agreements, resident and nonresident taxation, Form W-4 equivalents, state unemployment insurance, wage and hour law requirements and garnishment withholding including the aftereffects of COVID-19 on these areas! 

Complying with the tax code, tax withholding requirements and deposit schedules for the IRS and one state is complicated enough. But for the multistate employer, multiply this by 5, 10, or 20 or even 50 and it can turn into a payroll department's nightmare. Add the post-pandemic shakeup and resettling to this mix and you can have the makings of a horror movie! Not only are there more rules and regulations to comply with, but the penalties can multiply if mistakes are made.

All payroll professionals must know the taxation and reporting requirements for all states where the company has employees working or in the case of reciprocal agreements, living.  But for the payroll department that must handle employees who work in multiple states simultaneously or who travel to different states at different times for the employer the taxing and reporting requirements can become an arduous task at best and at worse a total fiasco.  Employees working from home can add even more to the complexity! Questions must be answered, sometimes on an employee by employee or even tougher on a case-by-case basis for an individual employee. Which state income tax is withheld? Does it matter if the employee is a resident or a nonresident of the state? Are there any reciprocal agreements in effect that must be taken into consideration?  Which state do we pay the SUI to and what happens if one of the states has disability insurance but the other doesn’t? Or worse yet what if both states require disability insurance to be deducted?

Some employers may even think they have solved this logistics and regulations nightmare by simply withholding the income for and paying the SUI over to the state where the employee lives.  And this might appear to be good in theory but in actual practice it is an audit disaster waiting to happen and happen it will. Only if the employee is performing some work in the state in which they live would the employer have a hope of passing the audit for paying the SUI.  But when it comes to state income tax audits it won’t even come close. Most states require state income tax withholding for wages paid for work performed in the state.  The only ground given in this area is usually for reciprocal agreements and nonresident employees who may be in the state for a limited time. No, the only way to determine the proper taxation for multiple state employees is by researching and apply the requirements for each state. And this is where this webinar will help. This webinar will cover the intricacies and requirements that must be addressed by the multistate employer.

Also, an employer with employees working in multiple states does not just have taxes to deal with. Now there are also wage and hour laws to contend with! In a different (read: higher) minimum wage? Are the overtime rules different? Would that employee still be exempt?

Arizona Form A-4: Arizona law requires your employer to withhold Arizona incometax from your wages for work done in Arizona. The amountwithheld is applied to your Arizona income tax due when youfile your tax return. The amount withheld is a percentage ofyour gross taxable wages from every paycheck. You mayalso have your employer withhold an extra amount from eachpaycheck.

California DE4 Form: This certificate, DE 4, is for California Personal Income Tax (PIT) withholding purposes only. The DE4 is used to compute the amount of taxes to be withheld from your wages, by your employer, to accurately reflect your state tax withholding obligation.

Exempt : Exempt employee is a term that refers to a category of employees set out in the Fair Labor Standards Act. They do not receive overtime pay, nor do they qualify for the minimum wage

Form CT-W4: Employee's Withholding Certificate, provides your employer with the necessary information to withhold the correct amount of Connecticut income tax from your wages to ensure that you will not be underwithheld or overwithheld.

Form CT-W4NA: Form CT-W4NA, in addition to Form CT-W4, Employee's Withholding Certificate, will assist your employer in withholding the correct amount of Connecticut income tax from your wages for services performed in Connecticut.

Form W-2: Form W-2 is an Internal Revenue Service tax form used in the United States to report wages paid to employees and the taxes withheld from them. Employers must complete a Form W-2 for each employee to whom they pay a salary, wage, or other compensation as part of the employment relationship. - Wikipedia (


Form W-4: Form W-4 (otherwise known as the "Employee's Withholding Allowance Certificate") is an Internal Revenue Service (IRS) tax form completed by an employee in the United States to indicate his or her tax situation (exemptions, status, etc.) to the employer.

Fringe Benefits: An extra benefit supplementing an employee's salary, for example, a company car, subsidized meals, health insurance, etc.

Garnishment: A legal summons or warning concerning the attachment of property to satisfy a debt

Minimum Wage: The lowest wage paid or permitted to be paid specifically fixed by a legal authority or by contract as the least that may be paid either to employed persons generally or to a particular category of employed persons.

Nexus: The term nexus is used in tax law to describe a situation in which a business has a "nexus" or tax presence in a particular state or states. A nexus is basically a connection between a taxing jurisdiction, like a state, and an entity like a business that must collect or pay the tax.

Nonresident Alien (NRA): This income is taxed at a flat 30% rate, unless a tax treaty specifies a lower rate. Nonresident aliens must file and pay any tax due using Form 1040NR, U.S. Nonresident Alien Income Tax Return or Form 1040NR-EZ, U.S. Income Tax Return for Certain Nonresident Aliens with No Dependents.

Reasonable Cause : Reasonable cause is based on all the facts and circumstances in your situation. The IRS will consider any reason which establishes that you used all ordinary business care and prudence to meet your federal tax obligations but were nevertheless unable to do so.

Reciprocal Agreements: A reciprocal agreement, also called reciprocity, is an agreement between two states that allows residents of one state to request exemption from tax withholding in the other (reciprocal) state. This can save you the trouble of having to file multiple state returns.

Resident Alien : A resident alien is a foreign person who is a permanent resident of the country in which he or she resides but does not have citizenship. To fall under this classification in the United States, a person needs to either have a current green card or have had one in the previous calendar year.

State Unemployment Insurance (SUI): The Federal-State Unemployment Insurance Program provides unemployment benefits to eligible workers who are unemployed through no fault of their own.
