How to Claim Reciprocity: State Withholding Exemption Forms Explained
Claiming reciprocity requires the right form at the right time. This step-by-step guide walks through every state exemption form, when to submit it, and what to do if your employer refuses to honor it.
Claiming state tax reciprocity is a straightforward process, but it requires precision. File the wrong form, file it with the wrong party, or fail to verify your first paycheck, and you can spend the next twelve months untangling withholding errors. Roughly 16 states and the District of Columbia maintain reciprocity agreements with at least one neighboring state, and each state has its own exemption certificate. The mechanics of filing are similar across states, but the form numbers, submission timing, and verification steps differ in important ways.
This guide walks through the four-step process to claim reciprocity, provides a complete reference table of every state exemption form, and explains what to do when something goes wrong. We cite the IRS, the Federation of Tax Administrators, and individual state Departments of Revenue throughout. Use this as your procedural checklist, then run your numbers through our calculator to confirm the result.
The 4-step process to claim reciprocity
Step 1: Confirm your residence and work state have an active reciprocity agreement. Not every pair of neighboring states has reciprocity — California has no reciprocity with any state, and the New England states have none with each other. Check the official reciprocity matrix published by your work state's Department of Revenue, or use our reciprocity matrix at the top of the reciprocity category. You must be a bona fide resident of the residence state, meaning your domicile is there and you maintain a permanent place of abode there. Part-year residents may need to apportion their withholding.
Step 2: Obtain the correct exemption form for the work state. Each state publishes its own form — there is no universal federal reciprocity form. The form is typically available on the work state's Department of Revenue website or through your employer's HR portal. Make sure you have the current year's revision, since states periodically update form layouts. Download the form as a PDF and fill it in completely before submitting.
Step 3: Submit the form to your employer's payroll department. Do not send the form to the state directly — the state never sees reciprocity exemption forms unless the employer is audited. The employer retains the form on file and uses it to set up withholding. Submit the form on your first day of work, or as soon as you become aware that reciprocity applies. Most employers accept the form by email or through their HR portal; some require a physical signature.
Step 4: Verify your first paycheck reflects the exemption. After your first full pay period following submission, check your pay stub carefully. The work state's income tax line should be zero, and only your residence state's income tax should appear. If you still see work-state withholding after the first full pay period, follow up with payroll in writing immediately. The earlier you catch the error, the easier it is to fix.
Complete form reference table
The table below lists every state that participates in reciprocity, the exemption form number, who files it, and where to submit it. "Who files it" identifies which party submits the form to the employer — typically the employee.
| State | Form number | Who files | Where to submit |
|---|---|---|---|
| District of Columbia | D-4A | Employee | DC employer's payroll department |
| Illinois | IL-W-5-NR | Employee | IL employer's payroll department |
| Indiana | WH-47 | Employee | IN employer's payroll department |
| Iowa | IA 220 | Employee | IA employer's payroll department |
| Kentucky | 42A809 | Employee | KY employer's payroll department |
| Maryland | MW507 | Employee | MD employer's payroll department |
| Michigan | MI-W4 | Employee | MI employer's payroll department |
| Minnesota | MWR | Employee | MN employer's payroll department |
| Montana | Interstate Tax Withholding Exemption Certificate | Employee | MT employer's payroll department |
| New Jersey | NJ-165 | Employee | NJ employer's payroll department |
| North Dakota | NDW-R (Form 305) | Employee | ND employer's payroll department |
| Ohio | IT 4 | Employee | OH employer's payroll department |
| Pennsylvania | REV-419 | Employee | PA employer's payroll department |
| Virginia | VA-4 | Employee | VA employer's payroll department |
| West Virginia | WV/IT-104 R | Employee | WV employer's payroll department |
| Wisconsin | WI-220 | Employee | WI employer's payroll department |
The "where to submit" column is the same across all states: the employer's payroll department, never the state Department of Revenue. Many large employers operate a centralized payroll system that may be located in a different state from the work location; in those cases, submit the form to the centralized payroll contact identified by your HR department. Always keep a copy of the submitted form for your records.
What to do if your employer refuses to honor reciprocity
Occasionally an employer will refuse to honor reciprocity, either out of ignorance, because of a payroll system limitation, or because the employer's payroll provider does not support out-of-state withholding setup. The first step is to cite the specific reciprocity authority in the work state's tax code or administrative regulations. Provide the citation in writing to the payroll contact, and attach the completed exemption form. Most refusals are resolved at this stage once the employer realizes reciprocity is a legal entitlement, not a discretionary benefit.
If the employer still refuses, escalate to HR or to a senior payroll manager. Document the request and the employer's response in writing, including dates and names. The work state's Department of Revenue does not directly enforce reciprocity against employers, but the documentation supports your eventual refund claim. Continue filing the exemption form with each new employer in the meantime, and consider whether the work-state withholding on your paychecks will create a year-end refund obligation that requires a non-resident return.
If the employer ultimately withholds work-state tax despite the exemption form on file, you must file a non-resident return for the work state at year-end. Report zero work-state-sourced wages under reciprocity, claim the withheld tax as a refund, and attach a copy of the exemption form if requested. Most state Departments of Revenue process these refunds within 8 to 12 weeks of filing. You must also file your residence-state return reporting the full wages, and you may need to make estimated payments to cover the residence-state liability that should have been withheld throughout the year.
Multiple employers in the work state
If you have two or more employers in the work state — for example, a primary job and a part-time weekend job — you must file a separate exemption form with each employer. Reciprocity forms are employer-specific, and the exemption does not transfer between employers. Each employer's payroll system treats you as a separate employee, and each employer will withhold work-state tax by default until you file the form.
The same rule applies if you change employers within the work state during the year. Your new employer will require a new exemption form, even if you filed one with your previous employer. The new employer's payroll system has no way to know about the previous filing. Plan to submit the form on your first day at the new employer, just as you did for your first job.
For workers with simultaneous jobs in multiple work states, each state's reciprocity rules apply independently. A Maryland resident with one job in Virginia and another in Pennsylvania would file Form MW507 with both employers (claiming exemption from VA withholding and from PA withholding, respectively). Maryland state and county tax would apply to all wages. The administrative burden is higher but the principle is the same.
Reciprocity and supplemental wages
Reciprocity covers supplemental wages — bonuses, commissions, overtime premiums, and similar items — just as it covers regular wages. The exemption form on file with the employer applies to all wage income paid by that employer. A worker who files Form MW507 with a Virginia employer and receives a year-end bonus will see no Virginia income tax withheld from the bonus, only Maryland state and county tax.
Supplemental wages paid by a former employer after termination — for example, accrued vacation payout, deferred compensation distributions, or severance — may follow different sourcing rules. Some states source these payments to the state where the work was originally performed, while others source them to the state of residence at the time of payment. Workers receiving post-termination payments should consult a tax professional or the relevant Department of Revenue to confirm sourcing.
Stock options and restricted stock units (RSUs) present an additional wrinkle. Some states source equity compensation to the state where the work was performed during the vesting period, requiring apportionment across multiple states. Reciprocity may not apply to the apportioned portion that relates to work performed outside the residence state. Workers with significant equity compensation should work with a tax professional to verify proper sourcing and withholding.
When reciprocity does NOT apply
Reciprocity applies only to wage income paid by an employer in a reciprocity state to a resident of the partner state. Several common situations fall outside this scope, and workers should be aware of them to avoid surprises at year-end.
First, reciprocity does not apply to non-wage income. Self-employment income, partnership distributive shares, S-corporation pass-through income, rental income, royalties, and capital gains are sourced under the default rules of each state. A Maryland resident with consulting income from Pennsylvania clients cannot use the MD-PA reciprocity agreement to avoid Pennsylvania tax on that income; Pennsylvania's non-resident tax and Maryland's credit mechanism apply instead.
Second, reciprocity does not apply when the worker is not a bona fide resident of the reciprocity state. A worker whose domicile is in New York but who temporarily lives in Pennsylvania cannot claim PA-NJ reciprocity on wages earned in New Jersey. The residence state for reciprocity purposes is the worker's permanent legal residence — typically where they are registered to vote, hold a driver's license, and maintain their primary abode.
Third, reciprocity does not apply to wages earned by a statutory employee. Statutory employees — certain drivers, insurance agents, home workers, and full-time life insurance salespeople — are reported on Form W-2 with the statutory employee box checked, and their wages may follow different sourcing rules depending on the state. Some reciprocity agreements explicitly exclude statutory employees; others are silent. Workers in this category should consult the specific reciprocity statute or a tax professional.
Fourth, reciprocity does not apply when the worker performs services in a non-reciprocity state. A Maryland resident who travels to New York for client meetings may owe New York tax on the wages attributable to those workdays, even though Maryland has reciprocity with several states. New York's convenience rule applies, and the worker may need to file a New York non-resident return.
Fifth, reciprocity does not cover local taxes. As we explain in our state-specific reciprocity guides, Ohio's school district income tax, Maryland's county tax, Pennsylvania's local EIT, and Philadelphia's wage tax all follow separate rules and may apply even when state-level reciprocity is in effect.
Year-end reconciliation
At year-end, every worker with reciprocity should review their W-2 carefully. The W-2 reports wages and withholding in Boxes 1 through 14, with state-level information in Boxes 15 through 17 and local-level information in Box 18 through 20. Verify that the work state's withholding (Box 17) is zero or near-zero, and that the residence state's withholding (Box 17 for the residence state) reflects what you actually expect to owe.
If the work state's withholding is non-zero — either because the exemption form was filed late or because the employer failed to honor it — you must file a non-resident return for the work state to claim a refund. Most states require the non-resident return to be filed within the standard statute of limitations, typically three years from the original due date. Refunds are typically issued within 8 to 12 weeks of filing, though complex cases can take longer.
For the residence state, file your resident return reporting all wages, including those earned in the work state under reciprocity. You may need to make estimated payments during the year if the residence state's withholding through your out-of-state employer is insufficient. Many states impose underpayment penalties if you owe more than $1,000 at year-end and did not pay at least 90% of the current year's liability or 100% of the prior year's liability through withholding or estimated payments.
Common mistakes
The most common reciprocity mistake is forgetting to refile the exemption form after a move. If you move from Maryland to Virginia, your existing MW507 on file with a DC employer is no longer valid, and you must file a new exemption form reflecting Virginia residency. Workers who move mid-year often see incorrect withholding for several pay periods before they realize the issue.
Second is filing the wrong form. An Indiana resident working in Kentucky should file Kentucky's Form 42A809, not Indiana's Form WH-47, which is for the reverse situation. Always file the form published by the work state, not your residence state. The residence state's form is for residents of your state who work in other reciprocity states — the mirror situation.
Third is not keeping a copy of the submitted form. Employers occasionally lose exemption forms during system migrations or HR transitions, and you may need to prove that you filed. Always keep a digital copy of every exemption form you submit, organized by employer and year. A simple PDF folder labeled by employer name is sufficient.
Fourth is assuming reciprocity is automatic. It is not. Until you file the exemption form, the employer is legally required to withhold work-state tax. Workers who assume "the employer will figure it out" often end up filing for refunds at year-end and waiting months for the money to come back.
Fifth is overlooking local taxes. As we explain throughout this guide, reciprocity does not cover local taxes — and many reciprocity states have significant local levies. Workers should review their pay stub for city, county, school district, or other local withholding and verify that it is correct.
What to do next
Pull your most recent pay stub and identify every state and local tax being withheld. If you are a reciprocity commuter and see withholding for a state where you do not reside, file the appropriate exemption form with your employer immediately. If you have multiple employers in the work state, file a separate form with each. After filing, verify your next two paychecks reflect the exemption. At year-end, review your W-2 carefully and file any necessary non-resident returns to claim refunds of incorrectly withheld tax. Run your full-year numbers through our calculator to project your liability under reciprocity, then adjust your W-4 or estimated payments to close any shortfall before year-end.
