Filing Taxes in Two States After Moving

Key Takeaways  

• Filing taxes in two states after moving may be required if you permanently move during the tax year, often involving a part-year resident return for each state. 

• Your residency status and move date help determine which state can tax your income, but each state has its own residency rules. 

• Income must be properly allocated between states based on each state’s sourcing rules; you should not automatically divide income based on the number of months you lived in each state. 

• Working remotely or living in one state while working in another can create additional tax obligations, although reciprocity agreements may apply in certain situations. 

• Filing two state returns does not necessarily mean paying taxes twice; you may qualify for a credit for taxes paid to another state, depending on state-specific rules. 

• Keep records such as W-2s, 1099s, pay stubs, withholding information, lease or closing documents, and move-date records to support your residency and income allocation. 

Moving to another state during the year can make tax filing more complicated because you may have tax obligations in both your former state and your new state. In many cases, taxpayers who change states during the year file a part-year resident return for each state, reporting income according to each state’s residency and income-sourcing rules. However, the exact requirements depend on the states involved, when you moved, where you earned income, and whether you maintained connections to your former state. 

Understanding how state residency works, how to divide income between states, and how credits for taxes paid to another state work can help you avoid common filing mistakes. This guide explains what to know when filing taxes in two states after moving, including how to determine residency, allocate income, handle remote work, and avoid paying tax twice on the same income. 

Do You Have to File Taxes in Two States If You Moved? 

If you moved from one state to another during the tax year, you may need to file tax returns in both states. The most common situation is filing a part-year resident return in the state you left and another part-year resident return in the state where you established your new home. 

When You Usually Need to File Two State Returns 

Suppose you lived and worked in State A from January through June and permanently moved to State B in July. If both states impose individual income taxes and you established residency in State B after leaving State A, you will generally need to determine your filing requirements in both states. 

Your former state may tax income attributable to the period when you were a resident. Your new state may tax income attributable to the period after you became a resident. However, states do not all calculate part-year resident tax in exactly the same way. 

For example, some states require part-year residents to report total income first and then apply an allocation or proration percentage. Other states may have taxpayers separately identify income attributable to the state. 

This means you should not assume that simply dividing your annual income by the number of months you lived in each state will always produce the correct result. 

When You May Only Need to File One State Return 

Moving does not automatically mean you must file two income tax returns. 

For example, if you move from a state with an individual income tax to a state without one, you may still have to file a return with your former state, but your new state may not have an individual income tax return to file. 

You could also have a filing obligation in only one state if the other state’s income threshold, residency rules, or specific circumstances do not require a return. 

Another possibility involves state reciprocity agreements. Some states have agreements that allow certain residents who work across state lines to avoid filing a return in the state where they work. Eligibility requirements vary, so taxpayers should check the specific agreement between the states involved. 

What If You Moved but Kept the Same Job? 

Keeping the same employer after moving states can make state tax allocation more complicated. 

If you worked for the same employer before and after your move, your W-2 may contain wages and withholding information for both states. If it does not, you may need to use payroll records, pay stubs, or other documentation to determine how much income belongs to each state. 

The state where you physically performed your work can matter, but state sourcing rules can differ. Remote employees should pay particular attention to these rules rather than assuming their employer’s headquarters determines where their wages are taxable. 

How Does Moving to Another State Affect Your Taxes? 

Moving affects state taxes primarily because your residency status and income sources can change during the year. A mid-year move can turn what would otherwise be a single-state filing into a multi-state filing, while the specific tax consequences depend on the states involved. 

Your Move Date Matters for State Taxes 

Your move date can be an important piece of documentation when preparing part-year resident returns. 

If you lived in your old state from January 1 through June 30 and established residency in your new state on July 1, that date can help determine which income belongs to each residency period. 

However, your physical move date is not necessarily the only factor that determines when your residency changed. States may look at your domicile, intent, and other connections to determine whether you actually established or abandoned residency. 

Keep documentation that supports the date and circumstances of your move, such as a lease, home purchase documents, utility records, employment records, or other evidence of when you established your new home. 

Your New State May Have Different Tax Rules 

State tax laws can differ substantially. One state may have a different tax rate, filing threshold, standard deduction, credit structure, or definition of residency than another. 

Even the way a state calculates a part-year resident’s tax can vary. Some states start with income for the entire year and then apply a percentage based on the portion attributable to the state. Others use different allocation methods. 

As a result, don’t assume the tax return for your old state will work the same way as the return for your new state. 

Moving From a State With Income Tax to One Without It 

Moving to a state with no individual income tax can change your future state income tax obligations, but it does not necessarily erase the tax obligations you had before moving. 

For example, assume you lived in California from January through August and moved permanently to Texas in September. Texas does not impose an individual state income tax, but you may still have a California filing obligation for the period you were a California resident and for any California-source income that remains taxable after the move. 

California, for example, states that part-year residents generally pay tax on worldwide income while they are California residents and that nonresidents pay tax on taxable California-source income. 

The important point is that a move to a no-income-tax state does not automatically eliminate tax owed to the state you left. 

How to Determine Your State Tax Residency After Moving 

Before preparing your state returns, determine your residency status in each state. This is one of the most important steps when filing taxes in two states after moving because residency can determine which income a state can tax.  

Resident vs. Nonresident vs. Part-Year Resident 

A full-year resident generally lives in a state for the entire tax year or otherwise meets that state’s residency requirements. 

A part-year resident generally establishes or abandons residency during the tax year. Someone who moves permanently from one state to another during the year will often fall into this category in one or both states. 

A nonresident generally does not live in a state but may still owe tax there because of income sourced to that state. 

For example, a person who lives in State A but works in State B could potentially have a State B nonresident filing requirement while remaining a full-year resident of State A. 

What Factors Can Establish Residency? 

States can consider multiple factors when determining residency or domicile. These may include: 

• Where you maintain your primary home 

• Where you spend your time 

• Where your spouse or dependents live 

• Your driver’s license 

• Where you maintain personal belongings 

• Where you maintain financial or personal connections 

• Whether you intended to establish a permanent home in the new state 

There is no universal rule that says spending a particular number of days in a state automatically determines your residency for every state. Some states use day-count thresholds as part of their residency tests, but the complete rules vary. 

Can You Be Considered a Resident of Two States? 

It is possible for residency questions to become complicated when you maintain homes or significant connections in two states. 

For example, someone might purchase a home in a new state while retaining a residence in the former state and continuing to spend substantial time there. In such circumstances, both states may have rules that need to be considered. 

Don’t assume that getting a new driver’s license or moving your belongings automatically resolves every residency question. When the facts are complicated, review the residency rules for both states and consider getting professional tax advice. 

How to File Taxes in Two States After Moving 

The process of filing taxes in two states after moving generally involves determining your residency status, gathering documentation, allocating income, preparing the appropriate state returns, and checking whether you qualify for credits for taxes paid to another state. 

Step 1: Determine Your Residency Status in Each State 

Start by determining when your residency in the old state ended and when residency in the new state began. 

Review the residency rules for both states rather than relying solely on the date you physically crossed the state line. 

If you permanently moved during the year, you will often be a part-year resident of both states, but that is not universal. 

Step 2: Gather Your Income and Move-Related Records 

Before preparing your returns, gather documents that can help establish both your income and residency periods. 

Useful records may include: 

• State withholding information 

• Home purchase or sale documents 

• Records showing your move date 

Your W-2 is particularly important because it can show state wages and state income tax withholding. If the information does not accurately reflect your move, payroll records may help you determine the appropriate allocation. 

Step 3: Allocate Your Income Between the Two States 

Next, determine how much income belongs to each state. 

For wages, the process may be relatively straightforward if you changed employers when you moved. If you worked for the same employer throughout the year, however, you may need to calculate the amount earned during each residency period. 

The same principle does not necessarily apply to every type of income. Interest, dividends, capital gains, retirement income, rental income, and business income can have different sourcing rules. 

Step 4: File the Appropriate State Returns 

Once you’ve determined your residency status and allocated your income, file the appropriate return for each state. For many taxpayers, this means completing two part-year resident returns. In other circumstances, you might have one part-year resident return and one nonresident return. 

Follow each state’s instructions carefully because states can use different forms and calculations. 

Step 5: Check for Credits for Taxes Paid to Another State 

Finally, determine whether either state offers a credit for income taxes paid to another state. These credits are designed in part to prevent taxpayers from being taxed twice on the same income, although the rules and limitations vary by state. 

For example, Minnesota explains that a resident who pays tax to another state on income also taxed by Minnesota may qualify for a credit for taxes paid to the other state. 

Note: this credit works differently for two neighboring states. If you paid tax to Wisconsin, you’d use a separate form (Schedule M1RCR) instead. And if you had Michigan or North Dakota tax withheld, you’d file directly with that state for a refund, since Minnesota has reciprocity agreements with both. 

How Is Income Divided When You Move to Another State? 

Income allocation is one of the most important parts of a multi-state return because your annual income may need to be divided between the states according to residency and sourcing rules. 

Wages and Salary 

Consider a taxpayer who earned $90,000 from the same employer during the year and moved halfway through the year. 

If the employer did not provide a state-by-state breakdown, the taxpayer may need to determine how much of the $90,000 was earned before and after the move. Pay stubs, payroll records, time records, and other documentation can help. 

If the taxpayer earned $45,000 before the move and $45,000 afterward, the income allocation may be relatively straightforward. But if income fluctuated because of bonuses, commissions, overtime, or other compensation, a simple 50/50 split may not be accurate. 

Self-Employment and Freelance Income 

Self-employed taxpayers can face more complicated allocation issues. Suppose a freelancer earned $100,000 during the year, performing services while living in State A for the first six months and State B for the remaining six months. The taxpayer may need to determine which income is attributable to each state under the states’ specific sourcing rules. 

Don’t automatically assume that dividing annual business income by the number of months lived in each state is correct. State rules for business and self-employment income can depend on where services were performed, where the business operates, where customers receive the benefit of services, and other factors. 

California, for example, has specific sourcing rules for independent contractors and notes that the location where the customer receives the benefit of a service can matter. 

Investment, Retirement, and Other Income 

Not all income is tied directly to where you work. Interest, dividends, capital gains, pensions, IRA distributions, and other forms of income can have different state tax treatment. 

For example, if you received dividend payments while living in your old state and additional payments after establishing residency in your new state, the appropriate allocation may depend on the states’ rules and when the income was received. 

The same is true for capital gains. If you sell an investment shortly after moving, don’t automatically assume the gain belongs entirely to the new state. Review the sourcing and residency rules applicable to that type of income. 

What Happens If You Live in One State and Work in Another? 

You do not necessarily have to move to trigger multi-state tax obligations. Living in one state while earning income in another can also create state filing requirements. 

State Reciprocity Agreements Explained 

A reciprocity agreement is an arrangement between certain states that can affect how wages are taxed when someone lives in one state and works in another. 

When applicable, reciprocity can allow an employee to pay income tax primarily to their state of residence rather than the state where they physically work. 

However, these agreements generally apply only to specific types of income and have eligibility requirements. They are not universal. 

Before assuming reciprocity applies, verify that your particular states have an agreement and that your circumstances meet its requirements. 

What If the States Do Not Have a Reciprocity Agreement? 

Without reciprocity, you may need to file a resident return in your home state and a nonresident return in the state where you earned income. 

The resident state may provide a credit for qualifying taxes paid to the other state. The goal is generally to reduce the possibility of the same income being taxed twice, subject to each state’s rules. 

Remote Workers and State Taxes 

Remote work has made state tax questions more complicated. If you move but continue working remotely for the same employer, your employer’s location is not necessarily the only factor that determines your state tax obligations. 

For example, California specifically addresses situations involving residents who relocate and continue working remotely for California employers. The tax result can depend on where services are performed, residency status, and the nature of the income. 

If you work remotely after moving, review the rules of both states instead of assuming your employer’s state controls the tax treatment. 

How to Avoid Paying Taxes Twice After Moving 

Filing two state returns does not necessarily mean you’ll pay twice on the same income. State allocation rules and credits can help determine which state receives tax on particular income and can reduce double taxation when the same income is taxed by multiple states. 

Claiming a Credit for Taxes Paid to Another State 

Suppose State A taxes $30,000 of your income and State B also taxes that same $30,000. If State B allows a credit for qualifying taxes paid to State A, you may be able to reduce your State B liability. 

The credit is not necessarily a dollar-for-dollar refund of every tax paid to the other state. States can impose limitations and use their own calculation methods. 

Because of these differences, carefully follow the instructions for the state claiming the credit. 

Check Your State Withholding 

Compare the state income tax withheld from your paychecks with your actual state tax obligations. This is particularly important if you moved during the year and your employer continued withholding tax for your old state after you moved, or if payroll changes were not made immediately. 

Incorrect withholding does not necessarily change where income is taxable. It may instead result in an unexpected balance due in one state and a refund in another. 

Keep Documentation Supporting Your Move 

Keep records that support your residency change and income allocation. For example, maintain copies of your lease, closing documents, utility bills, employment records, W-2s, pay stubs, and state tax returns. 

These documents can be especially valuable if a state tax agency later questions when you became or ceased to be a resident. 

Common Mistakes When Filing Taxes in Two States 

Multi-state returns can become difficult when taxpayers make assumptions about residency, income allocation, or credits. Understanding the most common mistakes can help you avoid unnecessary tax problems. 

Assuming You Only Need to File in Your New State 

One of the most common mistakes is assuming that moving to a new state eliminates all obligations to the state you left. 

Your former state may still require a part-year return, and you may also have continuing tax obligations if you have income sourced to that state after moving. 

Reporting All Income to Both States Without Applying Allocation Rules 

Another mistake is reporting 100% of annual income as taxable income in both states without applying the appropriate allocation or proration rules. 

Some state returns begin with total federal income and then calculate an allocation percentage. Others require taxpayers to directly identify income attributable to the state. 

Forgetting About Nonresident Income 

Moving away from a state does not necessarily eliminate its ability to tax income sourced there. 

For example, you could move to another state but continue receiving rental income from property located in your former state. You could also continue operating a business or performing activities that create income sourced to the former state. 

Missing a Tax Credit for Taxes Paid to Another State 

Taxpayers sometimes overlook available credits because they assume each state return is completely separate. 

If two states tax the same income, check whether your resident state allows a credit for taxes paid to another state. 

Assuming Every State Uses the Same Residency Rules 

There is no single nationwide state-income-tax residency test. States can have different definitions, filing thresholds, allocation methods, and sourcing rules. A rule that applies in one state may not apply in another.

Frequently Asked Questions About Filing Taxes in Two States After Moving 

What Are the Tax Implications of Moving to Another State? 

Moving to another state may require you to file a part-year resident tax return in both your former and new states. Your tax obligations depend on when you moved, where you earned income, and each state’s residency and income-sourcing rules. 

How Does Moving Affect Taxes? 

Moving can change which state has the right to tax your income and may require you to allocate your income between two states. You may also qualify for a credit for taxes paid to another state to help prevent double taxation. 

Can I file one federal return if I lived in two states? 

Yes. Moving between states generally does not mean you need to file two federal individual income tax returns. Your federal return generally covers the entire tax year, while your state returns address the separate state tax requirements.
