Not automatically. A remote employee’s state income-tax obligations usually depend on two separate facts: the state where the employee is a tax resident and the state where the wages are treated as earned. An employer’s location can matter, especially when a state applies a convenience-of-the-employer sourcing rule, but it does not by itself determine the answer. You may owe tax in your home state, the employer’s state, or both, with any available resident credit governed by the states’ own rules.
New York illustrates why a simple “I work from home, so only my home state matters” assumption can fail. Its official guidance can treat certain home-working days as New York workdays when the assigned or primary office is in New York. That is a New York example—not a nationwide rule—so the correct analysis starts with both states’ current tax instructions.

What determines where a remote worker owes state income tax?
State tax analysis has two distinct parts: residency and income sourcing. Residency asks which state treats you as a resident for the tax year. Sourcing asks which state can tax a particular item of income, such as wages, based on where the work is considered performed under that state’s law.
A resident generally reports income under the resident state’s rules, while a nonresident is generally taxed only on income sourced to that state. The exact definitions, exceptions and filing thresholds differ by state. Therefore, a person who lives in State A and works remotely for an employer in State B must read both states’ guidance rather than rely on the employer’s headquarters alone.

Can an employer’s state tax wages earned from a home office?
Sometimes. Some states source wages to an assigned or primary office even when an employee works from home elsewhere. This type of rule is often called a convenience-of-the-employer rule, but the terminology and exceptions vary. Other states focus more directly on the employee’s physical work location.
New York’s Department of Taxation and Finance gives a clear example. Its telecommuting FAQ says: “If you are a nonresident whose primary office is in New York State, your days telecommuting are considered days worked in the state unless your employer has established a bona fide employer office at your telecommuting location.” Read the full New York telecommuting and residency FAQ for the agency’s definitions and exceptions.
That statement applies to New York’s rules and facts. It should not be generalized to every state. To determine whether an employer-state rule reaches your wages, look for language about the assigned office, primary office, convenience of the employer, bona fide employer office, or sourcing of nonresident wages in that state’s current instructions.
What does New York’s remote-work rule mean in practice?
Under the New York example, a nonresident with a primary office in New York may have home days counted as New York workdays unless the home location qualifies as a bona fide employer office. The distinction can change the portion of wages treated as New York-source income and, consequently, whether a nonresident return is required and how much tax is due.
The 2025 instructions for New York Form IT-203 explain that workdays are used to allocate wages earned partly inside and partly outside New York. The instructions address how days worked at home and days worked at the assigned or primary office enter the allocation. Keep the tax year in mind: instructions for a different year may change the treatment or filing mechanics.

New York’s guidance also distinguishes ordinary wage earners from employees whose compensation depends on sales volume and refers to separate methods for certain stock compensation. Do not apply a simple workday count to commissions, equity awards or another nonstandard compensation item without checking the method specified for that type of income.

Yes. New York’s FAQ expressly warns that someone living in one state and working in another may have liability in both states. Usually, the resident state may allow a credit for qualifying tax paid to another state, but the credit is not an automatic promise that every dollar will be offset.
Credit eligibility, the income that qualifies, ordering rules and limitations are controlled by the states involved. A credit can be limited to the resident state’s tax on the same income, and some taxes or income categories may not qualify. Review both states’ credit instructions and retain the other state’s return and proof of tax paid.
Reciprocity agreements can alter withholding and filing for residents of particular neighboring states, but they are state-pair specific. Do not assume that a payroll agreement exists merely because the states share a border or because your employer operates in both locations.
How is residency decided?
Residency is not determined solely by where your employer is incorporated or where your laptop is located. States commonly examine domicile (your permanent, primary home and intent), statutory day-count tests, and other connections. Each state publishes its own definitions, so apply the rules of the state claiming you as a resident.

New York’s current guidance describes domicile as the permanent and primary residence to which you intend to return or where you intend to remain. It also provides a statutory-resident test for a person who is not domiciled in New York but maintains a permanent place of abode there for substantially all of the year and spends 184 or more days in the state; any part of a day counts toward that threshold. This 184-day rule is a New York rule, not a nationwide standard. See the state’s residency FAQ for the current wording.
Moving during the year can create part-year-resident issues. Keep evidence of move dates, leases or home ownership, and the days physically spent in each state so you can support the residency position used on your returns.
Which facts should you collect before filing?
Gather the following information for the tax year:
- Your actual tax-residence state, including domicile facts and any day-count or permanent-abode test that could apply.
- The employer’s assigned or primary office shown in your employment records.
- The physical location where you performed work each day, including temporary work in another state.
- A count of workdays in each location, separated from vacation, sick leave, holidays and other nonwork days.
- Whether the employer established a bona fide employer office at your home or another remote location.
- States and amounts of withholding shown on Form W-2, plus any corrected W-2 or payroll notices.
- Whether you received commissions, sales-based pay, restricted stock, stock options or other equity compensation.
- Any reciprocity or resident-credit provisions in both states’ current instructions.
New York’s allocation instructions rely on workday counts, so a dated calendar, timesheet or planner can help organize records. No particular product is required; the important point is that your records reconcile to payroll and the allocation method used on the return.

Apply domicile, statutory-residence and day-count tests separately. If both states could claim residency, identify the tie-breaker or part-year rules in their instructions.
- Identify the wage-sourcing rule. Check whether the state uses physical work location, an assigned or primary office, a convenience-of-the-employer rule, or a special rule for your compensation type.
- Allocate the income. Follow the applicable state schedule and instructions for workdays, sales-based compensation or equity. Do not substitute an ordinary wage-day formula for a method written for commissions or stock.
- Check reciprocity. If the two states have an agreement covering your situation, determine whether it changes withholding, filing, or both.
- Calculate relief for overlap. Read the resident-credit rules in the resident state and verify what tax and income qualify. Compare the credit calculation with the tax actually imposed by the other state.
- Match returns to withholding. A W-2 can show withholding that does not match your final sourcing result. File the required resident, nonresident or part-year returns and claim refunds or make payments as the instructions require.
- Correct payroll prospectively. Give payroll the documented work location and any state withholding certificate or updated instructions your states require. A payroll correction does not replace filing a return for an earlier year.
When is a nonresident return likely?
A nonresident return is generally considered when you have income sourced to a state where you are not a resident and that state’s filing threshold is met. Thresholds and exceptions vary, so the presence or absence of withholding is not a reliable substitute for reading the filing instructions.

For a New York nonresident, wages treated as New York-source under the state’s telecommuting and workday rules can create a New York filing obligation even when the employee lives elsewhere. Conversely, withholding in a state does not prove that all of the wages are ultimately taxable there; it may need to be corrected through a return and credit calculation.
What mistakes cause remote workers to overpay or underpay?
- Using the employer address as the only test. Headquarters can matter under a sourcing rule, but it does not establish your residency by itself.
- Assuming every home day is sourced to the home state. A state such as New York may count telecommuting days differently when the assigned office is in-state.
- Applying one state’s rule nationwide. New York’s convenience-of-the-employer approach is an example, not a universal standard.
- Ignoring non-wage compensation. Commissions and equity may use methods different from ordinary salary workday allocation.
- Counting calendar days instead of workdays. Allocation instructions may require a workday denominator and specific treatment of leave, holidays or travel.
- Expecting a resident credit to erase all double tax. Credits have eligibility and limitation rules and may not cover every tax or income item.
- Failing to reconcile W-2 withholding. Incorrect state withholding can leave you with an unexpected balance due or a refund that requires a nonresident filing.
- Overlooking day-count residency. In New York, any part of a day counts toward the 184-day statutory-resident threshold; other states use their own tests.
What should you do if withholding appears wrong?
First, document the actual work locations and the sourcing rule that you believe applies. Compare that result with each state amount on your W-2 and with the employer’s payroll records. Ask payroll whether it can correct future withholding and whether a corrected wage statement is appropriate for the closed tax year.
For the filing year, prepare the required resident and nonresident returns using the state’s allocation schedule. Claim a refund where excess withholding occurred, pay any shortfall, and apply any available resident credit according to the credit state’s instructions. If the facts involve multiple moves, substantial travel, sales commissions or equity, a tax professional familiar with both states can help document the position.

Does the answer change for hybrid schedules or temporary travel?
Yes. Hybrid employees should track each workday’s physical location rather than label the entire job “remote.” A temporary assignment, coworking location or work performed while visiting family can create additional sourcing questions, especially if it changes the number of days attributed to a state or triggers that state’s filing threshold.
Use the instructions for the specific tax year and compensation type. New York’s 2025 IT-203 instructions are a reminder that allocation is an administrative calculation based on defined workdays and that separate methods can apply to sales-related or equity compensation.

What is the bottom line for remote workers?
You do not automatically owe income tax in the state where your employer is located, but you cannot dismiss that state either. Establish residency first, then apply each state’s wage-sourcing, reciprocity, credit and filing rules to the days and compensation you actually received. New York demonstrates how an employer-state rule can reach home-working days; the only safe nationwide conclusion is that the state pair and the tax year control the result.
Frequently Asked Questions
Do I need a nonresident return if my employer withheld tax for another state?
Possibly. Withholding can indicate that payroll treated wages as sourced to the employer’s state, but filing thresholds and sourcing rules determine whether a return is required. You may need the nonresident return to claim a refund, report correctly sourced wages or coordinate a resident credit.
Recommended Free Tools
What records prove where I worked during the year?
Keep a dated work calendar or timesheet showing the physical location for each workday, along with travel records, leave records and employer office information. Your records should support the workday totals used on the state allocation schedule and agree with payroll data.
Does a home office always count as an employer office for state tax purposes?
No. A personal workspace is not automatically a bona fide employer office. The state’s definition and the employer’s facts—such as whether the employer established and maintained the location for business purposes—control, so check the applicable guidance before excluding home days from employer-state sourcing.
How are stock awards or sales commissions sourced for a remote employee?
They may use methods different from ordinary salary workday allocation. State instructions can assign separate formulas or periods for sales-based pay and equity, so identify each compensation type and follow the tax year’s specific instructions rather than applying a salary day-count shortcut.
Can changing my payroll state fix a prior year’s tax problem?
Changing future withholding helps prevent the issue from recurring but does not amend a prior return or reverse tax already due. For an earlier year, reconcile the W-2, file the required state returns, request corrected wage statements when appropriate and claim any allowable refund or resident credit.
