Multi-State Tax Filing Done Right
Every Obligation. Every Credit.
Once.
Lived in one state, worked in another, moved mid-year? Multi-state tax filing is where the most expensive mistakes happen - and almost always, the person making them doesn’t know it until a state notice arrives.
Double taxation. Missed credits. Unfiled returns. All preventable.
At Griffin & Johnson, we handle multi-state tax filing routinely. We know the residency rules, the reciprocity agreements, the credit-for-taxes-paid calculations, and the part-year allocation methods for every state we encounter - so you file exactly where you’re required, claim every credit you’re owed, and never pay the same dollar in taxes twice.
Most Multi-State Tax Filers
Are Either Overpaying
or Underreporting.
Rarely Neither.
Multi-state tax filing is complicated because state tax rules don't coordinate with each other. Every state has its own residency definition, its own filing thresholds, its own reciprocity agreements - or lack of them. When you cross a state line to work, move mid-year, or earn income from property in another state, you've entered a landscape that most tax software was not designed to navigate correctly.
Here's what goes wrong when multi-state tax filing is handled without expertise: credit for taxes paid to another state was never claimed, a required non-resident return was never filed, the mid-year move was allocated wrong, or a reciprocity agreement was missed entirely.
Clients who self-prepare multi-state returns routinely miss the credit for taxes paid to other states. The result: they pay full tax to both states on the same income. That credit exists specifically to prevent this - but only if someone claims it.
Your Multi State Tax Filing
Situation May Be More
Complex Than You Realize
Multi state tax filing obligations often arise without anyone announcing them.
If any of the following describes your year, you almost certainly have filing obligations in more than one state - and the question isn’t whether you owe, it’s whether you’re claiming everything that reduces what you owe.
- ✓Remote workers with an out-of-state employer
- ✓Commuters crossing state lines for work
- ✓People who moved to a new state during the year
- ✓Military members with an out-of-state home of record
- ✓Military spouses with a different state of domicile
- ✓Business owners with income from multiple states
- ✓Investors with rental property in another state
Every Multi-State Tax Filing
Scenario, Handled Completely
No two multi-state tax filing situations are identical. We identify every filing obligation in your specific situation, prepare every required return, and make sure every available credit flows correctly - so you pay exactly what you owe, to exactly the right states, once.
Virginia Has Agreements
With Five Neighbors.
Most Commuters Don't Use Them Correctly.
A reciprocity agreement means you only file a tax return in the state where you live - not the state where you work. For Virginia commuters crossing into DC, Maryland, Kentucky, Pennsylvania, or West Virginia, this can eliminate an entire non-resident return and recover withholding that was taken from the wrong state all year. But the agreement doesn't apply itself. The employer must withhold for the right state, and refund claims must be filed if they didn't.
Agreements apply to wages and salaries only. Other income types are not covered.
This is more common than most people realize - especially for remote workers and new commuters. Your employer withheld taxes for their state. Reciprocity says you shouldn't owe that state anything. The solution is a non-resident refund claim filed with the employer's state and an exemption certificate going forward.
- 1File a non-resident return in the employer's state claiming a full refund of withheld taxes.
- 2Submit an exemption certificate to your employer so they withhold for Virginia going forward.
- 3File your Virginia return as the sole resident return, with all income reported there.
The Most Valuable Multi-State Tax Filing
Protections in the Federal Code
Go Unclaimed by Most Military Families.
Federal law gives active-duty service members and their spouses specific multi-state tax filing protections that can eliminate entire state tax obligations. But these protections are not automatic - they require correct analysis, correct documentation, and in some cases, specific elections filed with the state.
Your Home of Record Is Your Domicile.
Virginia May Not Be Entitled to Your Income.
The Servicemembers Civil Relief Act protects active-duty members from being taxed by their station state on military pay. If your home of record is Texas, Florida, or any other state, Virginia has no claim on your military compensation - even if you're stationed at Ft. Belvoir, the Pentagon, or Joint Base Myer-Henderson Hall.
The Military Spouses Residency Relief Act goes further: your spouse can elect to use your domicile state for tax purposes, potentially eliminating their Virginia tax obligation on civilian income earned here. The savings are real and the election is available - but only if it's claimed correctly.
