Quick summary
State and local tax planning for remote and cross-state workers reduces the chance of double taxation, improper withholding, and unexpected audits when you work from a different state or locality than your employer. This planning centers on residency rules, physical presence, employer payroll practices (nexus and withholding), reciprocal agreements, and available tax credits. Consult your CPA or a multistate tax advisor for tailored guidance—this article explains the practical steps and common pitfalls.
Why this matters now
Remote and hybrid work remain common after the pandemic, and state tax rules have continued to evolve. States vary widely in how they tax wages: some tax residents on worldwide income; others tax only income earned within the state. A remote worker who moves or who routinely performs work across state lines can unintentionally create tax filing obligations for multiple states, create payroll withholding mismatches, or establish a tax nexus for their employer. The result can be back taxes, penalties, and surprise payroll audits for employers and employees (IRS; state tax agencies).
Key concepts every remote worker should understand
- Residency vs. domicile: Residency rules determine whether a state taxes you as a resident; domicile is your permanent legal home. States use different tests—days present, ties (home, family, driver’s license), and intent—to determine status. (See state guidance.)
- Physical presence: Many states tax income earned while physically working in their borders, even if you are a nonresident.
- Convenience-of-employer rules: A minority of states apply a convenience-of-employer test, taxing income as sourced to the employer’s state if the remote work is for the employee’s convenience rather than the employer’s requirement. New York is notable for this rule; other states have similar tests or case law.
- Reciprocal agreements and tax credits: Some neighboring states have reciprocal agreements that exempt commuters from nonresident withholding. If no agreement exists, states commonly allow a resident credit to offset taxes paid to another state on the same income.
- Employer nexus and payroll withholding: An employee working in a state can create payroll and unemployment tax obligations for the employer, changing how withholding should be reported.
How state and local tax planning works in practice
-
Confirm where you are a resident or statutory resident. Check your new state’s residency tests (many use a day-count test such as 183 days or statutory-residency rules). Keep supporting evidence when you change residency: lease/mortgage documents, voter registration, driver’s license, utility bills, and where you spend nights.
-
Track where you work physically. Keep a contemporaneous log of work days by location. If you travel, record dates and primary work location. This documentation is often decisive when a state questions your filing status.
-
Update payroll and withholding forms. If you change states, file the correct state withholding form with your employer (for example, a state W-4 equivalent). If your employer mistakenly withholds for the wrong state, you may file a refund claim with that state and owe in your resident state.
-
Determine tax credit eligibility. Most states give residents a credit for income taxes paid to another state on the same income. That prevents double taxation but requires accurate reporting on both state returns.
-
Evaluate convenience-of-employer exposure. If your employer’s location uses convenience rules (notably New York), analyze whether your remote work is considered for your convenience. If so, that state could tax your wages even if you never set foot there while performing the work.
-
Consider employer-side effects. If you regularly work from a different state, your employer may need to register for withholding, unemployment insurance, and other payroll taxes in that state. If your employer resists adjusting payroll, document communications and consider seeking professional help.
Real-world examples and common scenarios
-
Example 1: A software engineer moves from New Jersey to Florida but continues to be employed by a New Jersey company. Florida has no individual income tax, but New Jersey may still require tax if the income is sourced there. The worker should update employer withholding and establish Florida residency with clear ties (driver license, voter registration) to avoid continued New Jersey withholding.
-
Example 2: An employee lives in California and is employed by a New York company. California taxes residents on worldwide income; New York may tax wages tied to services performed in New York. The employee may file a New York nonresident return for income earned in New York and claim a credit on the California return for taxes paid to New York.
-
Example 3: A commuter lives in Pennsylvania and works physically in New Jersey. Pennsylvania and New Jersey have reciprocal rules for certain taxpayers; if a reciprocity agreement applies, the worker files an exemption with the employer’s payroll to avoid nonresident withholding. See the FinHelp article on reciprocal agreements for commuters.
In my practice I’ve seen three recurring mistakes: failure to change withholding after a move, lack of work-location records, and assuming reciprocity where none exists. Correcting these early avoids large year-end liabilities.
Step-by-step checklist for workers who go remote or cross states
- Step 1: Create a work-location log and keep it current (dates, city/state, purpose of trip).
- Step 2: Update your driver’s license, voter registration, and address when you change domicile.
- Step 3: Notify payroll and submit the correct state withholding form promptly.
- Step 4: Ask payroll for a statement of state withholding; retain all pay stubs and W-2s.
- Step 5: If you worked in multiple states, compile tax returns and compute credits to avoid double taxation.
- Step 6: If you have significant moves or travel, consult a multistate CPA to model tax exposure.
Practical strategies and professional tips
- Keep contemporaneous records: In audits, contemporaneous records (calendars, travel itineraries, VPN logs, meeting notes) beat reconstructed memory.
- Use geolocation data cautiously: Employer-collected IP/VPN logs or meeting location metadata can be persuasive evidence but may carry privacy considerations.
- Time your domicile change: A mid-year move can create a part-year residency in two states; timing affects tax liabilities.
- Audit-proof your residency: Look for objective ties—home ownership, driver’s license, voter registration, and state tax withholding—to support your residency claim.
- Negotiate payroll: Ask your employer to update withholding quickly; employers often prefer avoiding multistate payroll complexity but may need documentation.
Common mistakes and how to avoid them
- Mistake: Assuming employer withholding equals final tax liability. Withholding is an estimate; you must file correctly with each state.
- Mistake: Relying only on physical presence while ignoring domicile rules. Some states tax residents regardless of where income was earned.
- Mistake: Believing reciprocity exists. Check state tax agency guidance—reciprocity is limited and often applies only to wage income between specific neighboring states.
Filing, credits, and audits—what to expect
If you owe tax to a nonresident state, you may file a nonresident return and claim a resident credit on your home-state return to reduce double taxation. Keep robust documentation—pay stubs, employer letters, and travel logs—because states review source and residency closely. States have different audit triggers; multistate issues are a common audit focus (state revenue departments; see individual state guidance).

A: Only some states apply it. New York is a well-known example; analyze the facts and employer policies.
Q: Can my employer be penalized for wrong withholding?
A: Yes. Employers can face payroll penalties and may need to correct returns; if you’re affected, document and inform payroll promptly.
