In the realm of medical sales, professionals often find themselves in complex situations that involve multi-state employment, varying tax jurisdictions, and the question of where they should be considered residents. This blog post will delve into the situation of a medical salesperson whose company is headquartered in California, but who resides in a Southern State, possibly Georgia, and covers territories that include California, Hawaii, Nevada, and Arizona. We will explore the intricacies of state taxation, employer requirements, and the possibility of maintaining residency in one state while working in another.

State Taxation and Residency

The first and most critical point to address is the concept of residency for tax purposes. Residency is usually determined based on the location of your primary home, voter registration, driver's license, vehicle registration, and where you consider your "domicile." In your case, you have established Georgia as your residence with all the requisite documentation.

From a tax perspective, it is indeed possible to maintain your Georgia residency while working in California, Hawaii, Nevada, and Arizona. However, your employer seems to have some concerns about liability, which we'll explore further.

Employer Requirements and Taxation

Your employer's decision to change your state tax withholding to California seems to be motivated by a variety of factors. One crucial aspect is the company's potential liability for not correctly allocating state income tax. When you work in different states, businesses must navigate complex tax laws and ensure they are appropriately withholding taxes and paying state fees. Your employer may have discovered that paying taxes to Georgia for an employee working primarily in California incurs additional costs and legal obligations. This may explain their desire to switch your state tax withholding to California.

As for your proposal to provide an address in Nevada to avoid state income tax altogether, the situation becomes more complex. Employers typically designate one state as the employee's "base" for tax purposes, usually the state where you spend most of your time working. In your case, it appears that California was chosen as the base due to your primary work location there. Attempting to change your base state to Nevada could pose challenges, as your employer may require you to maintain the California address to align with their expectations and their legal obligations in the state.

Multi-State Taxation and Commissions

Your idea about filing state income taxes separately for each territory you cover—California, Hawaii, Nevada, and Arizona—is indeed valid in theory. Athletes on the PGA Tour often have to pay taxes in multiple states, depending on their tournament winnings in each state. However, this approach is often used for independent contractors, and tax regulations for salaried employees can be different. Your company may have chosen to use the "base state" approach for simplicity and to avoid the complexities of managing state income taxes in every territory.

Reciprocity Agreements

One essential factor to consider is the existence of reciprocity agreements between states. Reciprocity agreements are established between states to simplify the tax obligations of residents working across state lines. In your case, if there is a reciprocity agreement between Georgia and California, you might be able to maintain your Georgia residency without incurring additional tax burdens when working in California. However, this might not be the case for Hawaii, Nevada, and Arizona, as they do not have to adhere to the same reciprocity agreements as California.

Communication and Collaboration

In addressing this complex tax situation, open and transparent communication with your employer and their accounting team is crucial. It is essential that you understand your company's reasons for changing your state tax withholding to California and inquire about any reciprocity agreements that may exist. You can discuss the feasibility of maintaining Georgia as your residency and how it aligns with company requirements. Additionally, you should consult with a tax professional who can provide guidance tailored to your specific situation.


In the world of medical sales, state taxation can be a labyrinthine puzzle, especially when you are employed by a company headquartered in one state while residing and working in others. Maintaining residency in your chosen state, like Georgia, is possible, but it is essential to consider your employer's requirements, potential liability, and the implications of reciprocity agreements. A transparent and collaborative approach, along with consultation with tax professionals, can help you navigate this intricate taxation landscape while preserving your desired state of residency.
