The shift to remote work has turned what was once a problem for only the largest employers into a compliance issue for businesses of every size. Before remote work became widespread, most employees worked in one state, and the employer’s withholding obligation was straightforward. Now, a 10-person company might have employees in 8 different states, each with its own income tax withholding rules, unemployment insurance requirements, and registration obligations. The baseline rule is simple: if an employee works in a state, the employer must withhold that state’s income tax from the employee’s wages and remit it to the state. But the details vary enormously. Some states have reciprocal agreements that override this rule for border communities. Several states apply the “convenience of the employer” doctrine, which taxes income in the employer’s state even when the employee works elsewhere. And the question of whether a remote employee creates corporate income tax nexus for the business (requiring the business itself to file a return and pay income tax in the employee’s state) adds another layer of complexity.

✓Key takeaway

Multi-state remote worker tax obligations for employers:

Obligation	Details
State income tax withholding	Required in each state where an employee works
State unemployment insurance (SUI)	Owed to the state where work is performed
State payroll taxes	Varies by state (CA SDI, OR transit tax, WA paid leave, etc.)
Employer registration	Must register with each state’s tax/revenue department and unemployment agency
Corporate income tax nexus	A remote employee in a state may create nexus for the business
Workers’ compensation	Must carry coverage in each state where employees work

Convenience-of-the-employer rule states (as of 2025):

State	Rule	Impact
New York	If remote work is for employee’s convenience, income taxed in NY	NY employer with remote employee in FL: employee may owe NY tax on all wages
Connecticut	Similar to NY; but credit allowed for taxes paid to work state
Delaware	Applies convenience rule
Nebraska	Applies convenience rule
Pennsylvania	Applies convenience rule for nonresidents
New Jersey	Does NOT apply the rule (but has challenged NY’s rule)	NJ resident working for NY employer from home: NY claims tax, NJ gives credit

States with no income tax (no withholding required):

State
Alaska
Florida
Nevada
New Hampshire (wages not taxed)
South Dakota
Tennessee
Texas
Washington
Wyoming

Reciprocal agreements (selected):

States	Agreement
VA, DC, MD	Residents taxed only in state of residence
IL, IA, KY, MI, WI	Various bilateral agreements
PA, NJ	Reciprocal for wages (not business income)
IN, KY, MI, OH, PA, WI	Various bilateral agreements
MN, MI, ND, WI	Various bilateral agreements

How do multi-state remote workers affect business taxes?

Hypothetical example

Round numbers. A company headquartered in New York has 10 employees: 5 in New York, 2 in New Jersey, 1 in Florida, 1 in California, and 1 in Texas.

Withholding obligations:

Employee Location	State Income Tax Withholding	Notes
New York (5 employees)	New York	Straightforward
New Jersey (2 employees)	New Jersey + possible New York (convenience rule)	NJ residents working remotely for NY employer: NY may claim withholding; NJ gives credit
Florida (1 employee)	None (no state income tax) + possible New York (convenience rule)	If remote work is for employee’s convenience, NY may claim withholding
California (1 employee)	California	CA taxes from Day 1; no convenience rule issue
Texas (1 employee)	None (no state income tax) + possible New York (convenience rule)	Same as Florida

Impact of New York’s convenience rule:

Employee	Salary	NY Withholding (if convenience rule applies)	Work State Withholding	Double Tax?
NJ employee	$100,000	$6,500 (NY)	$5,525 (NJ)	NJ gives credit for NY tax paid
FL employee	$100,000	$6,500 (NY)	$0 (no FL tax)	Employee pays NY tax despite living in FL
TX employee	$100,000	$6,500 (NY)	$0 (no TX tax)	Employee pays NY tax despite living in TX

Convenience rule defense: if the employer requires the employee to work remotely (e.g., no office space available, employer closes the office, employer’s business need), the rule does not apply.

Corporate income tax nexus from remote employees:

State	Employee Present	Corporate Nexus Created?	Business Must File?
New York	Yes (5 employees)	Yes (headquarters)	Yes
New Jersey	Yes (2 employees)	Yes (physical presence)	Yes (if income exceeds $0)
Florida	Yes (1 employee)	Yes (physical presence)	Yes (if taxable income; 5.5% rate)
California	Yes (1 employee)	Yes (physical presence)	Yes (franchise tax: minimum $800 + 8.84% on apportioned income)
Texas	Yes (1 employee)	Yes (physical presence)	Yes (franchise/margin tax: 0.375-0.75% on revenue if > $2.47M)

Apportioned income (single-sales-factor, common in most states):

State	Sales in State	% of Total Sales	Apportioned Income ($500K total)	State Tax
New York	$2,000,000	40%	$200,000	$13,000
New Jersey	$500,000	10%	$50,000	$4,500
California	$1,000,000	20%	$100,000	$8,840
Florida	$250,000	5%	$25,000	$1,375
Texas	$250,000	5%	$25,000	$0 (below $2.47M threshold)
Other states	$1,000,000	20%	$100,000	Varies

State registration requirements per remote employee:

Requirement	Details
State tax withholding registration	Register with state tax/revenue department
State unemployment insurance	Register with state unemployment agency; obtain SUI rate
Workers’ compensation	Obtain coverage in the employee’s state
State new hire reporting	Report new hire to state within 20 days
Local taxes	Some cities/counties have their own withholding (NYC, Philadelphia, Portland, etc.)
Estimated annual cost per additional state	$500-$2,000 (compliance, filing, software)

De minimis thresholds (selected states):

State	Threshold Before Withholding Required
California	No threshold (Day 1)
New York	No threshold (Day 1)
Illinois	30 days
Georgia	No threshold
Massachusetts	No threshold
Colorado	No threshold
Pennsylvania	No threshold

Planning strategies:

Strategy	Benefit
Hire in no-income-tax states	No state withholding (FL, TX, TN, NV, WA, WY, SD, AK, NH)
Document employer necessity for remote work	Defeats convenience-of-employer rule
Use reciprocal agreements	Simplifies withholding for border-state employees
PTET election	Deducts state income taxes at entity level (avoids SALT cap)
Consider PEO/EOR	Professional employer organization handles multi-state compliance
Annual nexus review	Evaluate whether each state filing is still required
