A certificate of nonresidence is a form you file with your employer to stop your work state from withholding income tax when you live in a state that has a reciprocity agreement with it. With the certificate on file, payroll withholds only for your home state. Without it, the work state keeps taking its cut by default, and you have to chase a refund when you file your taxes. About 30 states and the District of Columbia participate in at least one reciprocity arrangement, and filing the right form is the only way to use them.
When You Actually Qualify
The certificate only works if your specific home state and work state have an agreement with each other. Living in a participating state is not enough on its own. The pairings are bilateral, so check that your exact combination appears below.

Reciprocity covers only earned income: salaries, wages, tips, commissions, and bonuses paid to an employee. Investment income, rental income, and business income sourced in the work state are not covered, and you may owe tax in that state on those amounts regardless of what certificate you filed.
Getting the Right Form
Each work state publishes its own version. Common ones include Ohio’s IT-4NR, Maryland’s MW507, Virginia’s VA-4, Indiana’s WH-47, and Pennsylvania’s REV-419. Names and layouts differ; the information they ask for does not really vary.
You’ll provide your full legal name, Social Security number, and current home address. The home address is the whole point of the form: it shows that you live in a state with an active agreement with the work state. Some forms also want your employer’s name and state withholding account number, so ask payroll before you start filling anything in.
Every version has a residency declaration you sign, usually under penalty of perjury. You are affirming that you are a legal resident of the reciprocating home state and that you do not maintain a permanent home in the work state. Legal residence here means the state you consider your permanent home and intend to return to. Owning a vacation property in the work state does not automatically disqualify you; keeping a primary residence there does.
A few forms ask for the date your residency in the home state began. This matters most if you moved recently. You can generally claim the exemption from your residency start date forward, but the work state may still be owed tax on wages you earned before you moved.
Submitting the Certificate
The form goes to your employer’s payroll or human resources department, not to any state tax agency. Payroll reviews the form, verifies it is complete, and updates your withholding profile. The state never sees the form unless it audits your employer.
The change usually takes one or two pay cycles to appear. Check your pay stubs after submitting to confirm that work-state withholding has stopped and home-state withholding has started or continued. If both states are still showing deductions after two full pay periods, follow up with payroll right away rather than waiting for year-end.
Your employer keeps the certificate on file. It protects the employer if a state auditor later questions why work-state taxes were not withheld, but the accuracy of the residency claim is still on you.
Situations Where the Certificate Won’t Help
Reciprocity applies only to employees. If you work as an independent contractor or are otherwise self-employed, these agreements do not help you. Employers do not withhold state taxes for 1099 workers to begin with, so there is no withholding to redirect. You remain responsible for paying income tax to every state where you earn income, typically through estimated payments and nonresident returns.2New Jersey Division of Taxation.

Remote work is the other complication. Reciprocity agreements were built for commuters who physically cross a state line. A handful of states apply a “convenience of the employer” rule that taxes nonresident employees based on where the employer’s office sits, even when the employee works from home in another state. Connecticut, Delaware, Nebraska, New York, and Pennsylvania currently apply some version of this test. If your employer is based in one of these states and you work remotely from a neighboring state, the employer’s state may still claim the right to tax your wages because the remote arrangement is for your convenience rather than a requirement of the job. Reciprocity generally applies based on where work is physically performed, so if you work entirely from your home state, a certificate filed in the employer’s state may not even be the right tool. This is one situation where a tax professional pays for itself quickly.
Local taxes are a separate layer. State reciprocity does not necessarily extend to city or municipal income taxes. This matters most in Ohio and Pennsylvania, where many municipalities impose their own income taxes on workers. You may be exempt from the state tax and still owe local tax to the city where you work. Payroll can tell you whether local withholding applies.
Keeping the Exemption Current
Filing once and forgetting is a mistake. Some states require a new certificate at the start of each calendar year to confirm that your residency has not changed. Others treat the certificate as valid until you file a replacement. Check the instructions on the form you filed, or ask payroll whether annual renewal is expected.
Moving triggers a reassessment. Moving to a different state that has its own reciprocity agreement with your work state means filing a new certificate with the updated home state. Moving to a state with no such agreement ends the exemption entirely. Tell your employer right away so payroll can start withholding work-state taxes. Otherwise you’ll face an unexpected bill at filing time, plus possible underpayment penalties and interest.
Changes on the work side matter too. If your employer transfers you to an office in a state that does not have reciprocity with your home state, the old certificate stops applying. The same goes if you take a second job in a non-reciprocating state.
Recovering Taxes Already Withheld
If your employer withheld for the work state when you should have been exempt, you can get the money back, but not automatically. You file a nonresident income tax return in the work state at year-end, report your wages, and claim a refund for the full amount withheld. You’ll need your W-2 showing the work-state withholding, proof you lived in a reciprocating state during the period, and, if you have one, a copy of the exemption certificate you should have filed. Most states let you claim a refund within three years of the original filing deadline or two years from the date the tax was paid, whichever is later, though exact deadlines vary.
Refunds are slow. Depending on the state, you could wait several months. Filing the certificate when you start a job, or immediately after a move, is always better than trying to claw the money back later. If you start a job mid-year, submit the certificate right away so at least the remaining pay periods reflect the correct withholding.
Penalties for a False Claim
Claiming an exemption you don’t qualify for has real consequences. Willfully supplying false information on a withholding certificate is a federal misdemeanor punishable by a fine of up to $1,000, imprisonment for up to one year, or both.3Office of the Law Revision Counsel. 26 USC 7205 – Fraudulent Withholding Exemption Certificate or Failure to Supply Information That penalty sits on top of whatever the states impose. State penalties vary but typically include the back taxes you should have paid, interest from the date those taxes were originally due, and additional fines or fraud penalties depending on the jurisdiction.
The more common problem is not fraud but neglect. Someone moves out of a reciprocating state and forgets to update their withholding. The legal exposure is lower when the error is not willful, but you still owe the back taxes and interest. Treat any address change the way you’d treat updating your driver’s license: as a prompt to review your withholding status the same week.
