Do I Need a CPA If I Earn Income in Multiple States? A Guide for Massachusetts Residents
Posted On: Thursday, October 15, 2026
Do you live in Massachusetts but work in another state? Maybe you commute to Rhode Island, work remotely for a New York company, or own rental property outside Massachusetts. If so, you may be wondering: Do I have to file tax returns in multiple states, and will I be taxed twice on the same income?
For Massachusetts residents, earning income across state lines can complicate tax preparation. Understanding the rules can help you avoid unnecessary taxes, missed credits, and filing mistakes.
Does Massachusetts Tax Income Earned in Other States?
Yes. According to the Massachusetts Department of Revenue (DOR), full-year Massachusetts residents generally must report taxable income from all sources, regardless of where it was earned.
That means if you live in Sudbury, MA, but earn income from an employer in Rhode Island, Connecticut, or New York, that income generally must be included on your Massachusetts tax return.
Depending on the other state’s tax laws, you may also be required to file a nonresident income tax return there.
This applies to several types of income, including:
- Wages earned while working in another state
- Self-employment or business income
- Rental income from out-of-state properties
- Certain partnership or investment income
However, the state where income is taxable depends on the type of income and applicable state laws.
Will I Have to Pay Income Taxes Twice?
This is one of the biggest concerns for taxpayers earning income in multiple states.
Fortunately, Massachusetts offers an Other Jurisdiction Credit (OJC) that may help prevent double taxation.
Under Massachusetts law, eligible residents can claim a credit for certain income taxes owed to another state on income also taxed by Massachusetts.
For example, if you live in Massachusetts but earn taxable wages while physically working in Rhode Island, you may owe Rhode Island income tax. You may then qualify for a Massachusetts credit for those taxes.
However, the credit is not unlimited. Generally, it cannot exceed the Massachusetts tax attributable to the same income or the qualifying tax owed to the other jurisdiction, whichever is less.
Eligible taxpayers generally claim this credit using Massachusetts Schedule OJC.
What If I Work Remotely for an Out-of-State Company?
Remote work has introduced additional tax questions for Massachusetts residents.
Suppose you live in Sudbury but work remotely for a company headquartered in New York.
Does that automatically mean you owe New York income taxes?
Not necessarily.
Some states generally tax nonresidents based on where they physically perform their work. However, New York has special rules, including its “convenience of the employer” rule, which may affect employees working remotely from another state.
Your tax obligations can depend on your employer’s location, where you physically work, and the other state’s specific tax regulations.
This is an area where professional tax guidance can be especially valuable.
What If I Move Into or Out of Massachusetts During the Year?
Moving between states can create another layer of complexity.
Massachusetts distinguishes between full-year residents, part-year residents, and nonresidents.
If you move into or out of Massachusetts during the tax year, you may need to file Massachusetts Form 1-NR/PY.
Part-year residents generally report income from all sources during their Massachusetts residency period, along with Massachusetts-source income earned while they were nonresidents.
Properly establishing your residency dates is important for determining which income Massachusetts can tax.
When Should You Hire a CPA for Multistate Taxes?
While some multistate returns are relatively straightforward, others require careful coordination between state tax laws.
Working with a CPA can be particularly helpful when you:
- Work in one state but live in another
- Work remotely for an out-of-state employer
- Own rental property or a business in another state
- Relocate during the tax year
- Receive income from partnerships operating across state lines
A knowledgeable CPA can help determine filing requirements, calculate available credits, and identify opportunities for proactive tax planning.
