Pay Stubs for Remote & Multi-State Workers: Who Withholds?

The Problem with Multi-State Pay Stubs

Remote work turned what used to be a narrow payroll issue into something almost every worker asks about: which state is taking tax out of my paycheck? A software engineer in New Jersey working for a New York employer, a consultant in Tennessee flying to clients in Georgia weekly, a salesperson splitting time between Illinois and Indiana: each sees state tax lines that can look wrong even when they're correct.

State withholding depends on three things: where you're physically working, where your employer is located, and whether those two states have a reciprocity agreement. Residency is not on that list, and that's the most common and most expensive misconception. This article breaks down each rule and shows where remote workers lose money at tax time.

One distinction worth pinning down early: state withholding is not the same as state tax liability. Your employer withholds from one state; you may owe tax to another and get a credit for taxes paid elsewhere. Misreading which is which costs money.

The Default Rule: Work State Withholds

The state where you physically work is the state that withholds. You live in Pennsylvania but commute to Delaware? Your employer withholds Delaware tax on Delaware wages. Split the week between Pennsylvania and Delaware? Pennsylvania gets the Pennsylvania wages, Delaware gets the Delaware wages. Most employers track the primary location and default there unless you correct them.

Fully remote workers get withheld for their home state, wherever they actually sit. A California employee of a Texas company working from a California apartment earns California-source income, and the Texas employer must register in California and withhold. The remote-work transition of 2020–21 was expensive for employers: many opened remote hiring nationwide without registering in every state where their employees lived, then spent years unwinding the payroll tax exposure.

Your pay stub shows work-state tax on a line labeled with the state code: "CA SIT" for California, "NY SIT" for New York. If a state on your stub doesn't match where you're physically working, flag it with payroll that week, not in April.

Reciprocity Agreements: When the Home State Withholds Instead

A reciprocity agreement is a bilateral arrangement between two states under which a resident of one who works in the other has wages taxed only by the home state. These agreements exist because metro areas cross state lines and otherwise commuters would file two state returns every year. Reciprocity is pairwise, not a regional cluster, so each pair has to be checked individually, and the partner lists do change.

The major reciprocity partners as of 2026, by state:

• District of Columbia: every state (DC taxes only DC residents on wages).
• Illinois: Iowa, Kentucky, Michigan, Wisconsin. (Illinois ended reciprocity with Indiana years ago: Indiana is no longer on the IL list.)
• Indiana: Kentucky, Michigan, Ohio, Pennsylvania, Wisconsin.
• Iowa: Illinois.
• Kentucky: Illinois, Indiana, Michigan, Ohio, Virginia, West Virginia, Wisconsin.
• Maryland: Pennsylvania, Virginia, West Virginia, District of Columbia.
• Michigan: Illinois, Indiana, Kentucky, Minnesota, Ohio, Wisconsin.
• Minnesota: Michigan, North Dakota.
• Montana: North Dakota.
• New Jersey: Pennsylvania.
• North Dakota: Minnesota, Montana.
• Ohio: Indiana, Kentucky, Michigan, Pennsylvania, West Virginia.
• Pennsylvania: Indiana, Maryland, New Jersey, Ohio, Virginia, West Virginia.
• Virginia: Kentucky, Maryland, Pennsylvania, West Virginia, District of Columbia.
• West Virginia: Kentucky, Maryland, Ohio, Pennsylvania, Virginia.
• Wisconsin: Illinois, Indiana, Kentucky, Michigan.

The dense commuter corridors (NJ-PA, MD-PA-VA-WV-DC, and the Great Lakes pairings) drive most of these agreements. Each pair has its own claim form filed with the work-state employer: PA's REV-419 for a NJ resident working in Pennsylvania, Maryland's MW-507 for a reciprocal-state resident working in Maryland, Ohio's IT-4NR for a reciprocal-state resident working in Ohio, and so on. Without the form, payroll defaults to work-state withholding and you recover the money through a nonresident return.

Reciprocity isn't automatic. The form has to be on file with the employer to take effect, ideally before the first paycheck, and many remote workers never file one because they don't know it exists. Updating it after a move or a job change matters too: the old state can keep withholding for months if no one tells payroll otherwise.

The Convenience of the Employer Rule

A handful of states apply a "convenience of the employer" rule: if a remote worker is employed by an in-state employer but performs the work from another state for the worker's own convenience rather than the employer's necessity, the wages stay sourced to the employer's state for tax purposes. Put plainly, the worker's choice to work from home doesn't move the tax bill.

As of this review, commonly cited examples include:

• Full convenience rule: New York, Pennsylvania, Delaware, Nebraska, and Alabama. (Arkansas had a temporary convenience rule in place from February 2020 to April 21, 2021; it has not applied since. Oregon applies only a narrow version to certain nonresident managerial employees.)
• Reciprocal convenience rule. Applies only to residents of states that themselves apply a convenience rule: Connecticut and New Jersey (enacted in 2023). Massachusetts's COVID-era rule under 830 CMR 62.5A.3 sunset in 2021 and was not made permanent, so it no longer applies.

Treat that list as a starting point, not filing advice. Confirm the rule, effective date, reciprocity condition, and employer-necessity test with each state's revenue department before preparing payroll or a return.

New York's TSB-M-06(5)I is the strictest version and the source of most of the litigation. A New Jersey resident working remotely for a New York employer is treated as earning New York-source income unless the employer "requires" the remote work. Personal convenience does not clear that bar: "My apartment is quieter" doesn't qualify; "the employer closed its New York office" does. The pay stub correctly shows New York withholding, and the worker also files in New Jersey as a resident. New Jersey grants a credit for tax paid to New York on those wages, which usually eliminates most of the New Jersey tax on that income, but because the credit is capped at what New Jersey itself would have charged, the worker effectively pays at New York's higher rates.

There's also an employer side to this that workers often miss. An employer that fails to register and withhold properly in the state where the employee actually works picks up retroactive exposure: back tax, interest, and penalties from the date the worker became taxable in that state, not just from the date payroll noticed the problem. Fixing a stale withholding setup is not a "going forward only" cleanup for the employer, and that's why employers usually act quickly once an employee flags the issue.

How Multi-State Pay Stubs Are Formatted

Multi-state stubs vary by payroll provider. ADP, Gusto, QuickBooks, and Paychex each format them differently. ADP and Paychex list states on separate lines in the tax section, state code labeled. Gusto flags "Multi-State" in the summary and breaks each state out below. QuickBooks lists them sequentially with no header. Two-state stubs look messy.

For split weeks, the stub shows wage allocations next to each state's tax: "NY Wages 2,400.00 / NY SIT 168.00" and "NJ Wages 1,600.00 / NJ SIT 72.00." The allocation is how payroll divided your paycheck among states. If you travel regularly, ask payroll how they track it. Some use a fixed quarterly percentage; others recompute weekly from your time log.

Do not expect YTD state wage lines to add neatly to federal or gross wages. States can use different wage definitions, and the same earnings may appear in more than one state's wage base. Compare each line with the applicable state's allocation rules and ask payroll for its workday calculation when the figures are unclear.

Common Mistakes That Cost Remote Workers Money

The most common mistake is not telling your employer you moved. Payroll defaults to the last address on file. Move from California to Texas in March but update the system in September, and six months of California withholding stays on California's books. That error compounds: each missed paycheck means another amended return filing. You file a part-year return to claim it, a process that takes months.

Second: assuming the state W-4 equivalent is automatic. Many states have their own form (California DE 4, New York IT-2104, Illinois IL-W-4, and so on), and remote onboarding sometimes skips it. Without the correct state form, payroll may apply a statutory default that differs from the employee's situation. Unexpected state tax is a reason to review the address, work location, and withholding elections with payroll.

Third: conflating withholding with liability. The stub shows what payroll withheld in a given period; the state return reconciles what was actually owed. Wrong-state withholding is recoverable by filing a nonresident return in the withholding state and a resident return in your home state, but it's slow. Underpayment interest in the state you should have been paying all along is not recoverable; it accrues daily.

What to Do If Your Stub Looks Wrong

Send payroll a short written note with your home address, where you physically work each week, and a copy of the stub. Ask which state the employer is registered in for payroll and why the stub shows the state code it does. Most cases resolve within one pay cycle once the question is in writing.

If the employer isn't registered for payroll in the state where you actually work, your withholding will be corrected going forward, and the employer also picks up retroactive exposure for the periods it failed to register and withhold. The risk runs in both directions, which is why this resolves faster than most workers expect.

Mid-year moves are the most common cause of state-withholding errors. File a new federal W-4 and the new state's withholding equivalent the day the move is effective, not at the end of the year.
