How to Use This Convenience of Employer Rule Calculator
Select your employer state (the state applying the convenience rule), your residence state, and the number of days you physically work in the employer state. The calculator shows how each state claims to tax your income and whether residency credits eliminate double taxation.
This calculator is a simplified estimate. Your actual state tax depends on income, filing status, deductions, and whether you can establish employer-business-necessity for remote work. Consult a tax professional for specific advice.
The Key Rule
Under COE: Employer State taxes 100% of salary (even if you work remotely)
Residence State taxes 100% of salary (as a resident)
Credit: Residence state gives credit for taxes paid to employer state
Double Tax = max(0, Employer State Tax β Credit Allowed)
Credit Allowed = min(Employer State Tax, Residence State tax on same income)
Days-based allocation (without COE) = Salary Γ (Days in Employer State / 260)
Residence State taxes 100% of salary (as a resident)
Credit: Residence state gives credit for taxes paid to employer state
Double Tax = max(0, Employer State Tax β Credit Allowed)
Credit Allowed = min(Employer State Tax, Residence State tax on same income)
Days-based allocation (without COE) = Salary Γ (Days in Employer State / 260)
Example
Alex, NJ resident, working remotely for NY employer, $150,000 salary, 20 days in NY office:
Without COE: NY taxes 20/260 Γ $150,000 = $11,538 NY-source income
WITH COE (NY rule): NY taxes $150,000 (100%) β roughly $8,500 NY tax
NJ taxes $150,000 (100%) β roughly $6,500 NJ tax
NJ credit for NY taxes: min($8,500, $6,500 NJ rate applied) β reduces double tax
Effective double tax exposure: $1,000β$2,000 depending on NJ credit limit
Without COE: NY taxes 20/260 Γ $150,000 = $11,538 NY-source income
WITH COE (NY rule): NY taxes $150,000 (100%) β roughly $8,500 NY tax
NJ taxes $150,000 (100%) β roughly $6,500 NJ tax
NJ credit for NY taxes: min($8,500, $6,500 NJ rate applied) β reduces double tax
Effective double tax exposure: $1,000β$2,000 depending on NJ credit limit

Frequently Asked Questions
What is the convenience of the employer rule?
The convenience of the employer (COE) rule is a tax doctrine used by several US states (NY, CT, DE, NJ limited, PA, AR, NE) that taxes non-resident remote workers as if they were working in the employer's state β unless working remotely is required by the employer (not just for the employee's convenience). If you live in New Jersey but work remotely for a New York employer and your remote work is for your own convenience (not a business necessity), New York will tax your full salary as NY-source income.
Which states have the convenience of the employer rule?
As of 2026: New York applies COE most strictly β you must establish a bona fide employer office in your state to escape NY taxation. Connecticut applies COE for NY-based employees. Delaware has a similar rule. Pennsylvania applies COE for employers requiring NYC-area commuting. Arkansas and Nebraska have adopted limited versions. New Jersey applies a reverse COE only for NJ employers with NY employees. Most other states do not have COE rules and only tax income earned within their borders.
Can I get a tax credit to avoid double taxation?
Yes. Your state of residence typically gives a credit for taxes paid to another state. However, if both states tax the same income, the credit from your residence state may not fully offset the other state's tax (if residence state rates are lower) or may be limited. For example, a CT resident working for NY employer: CT taxes all income, NY also claims all income under COE. CT provides a credit for NY taxes paid, but only up to the CT tax on the same income. If NY rates are higher, you pay NY's higher rate.
How many days do I need to work in the employer's state to avoid the convenience rule?
There is no magic number of days. The key test is whether working remotely is for the employer's necessity (required by the employer's business needs) or your own convenience. Simply choosing to work from home for personal reasons doesn't satisfy the necessity requirement. New York has been litigated extensively on this. During COVID, NY released guidance that mandatory remote work (due to government orders) did qualify as employer necessity, but that ended with the pandemic. Post-2020, NY has resumed strictly applying the COE rule.
What should I do if I'm subject to the convenience rule?
Document any business necessity for your remote work arrangement β if your employer requires you to be in a different state (e.g., your team is all remote, there's no physical office, or you perform specialized work unavailable in the employer state), this can negate COE application. Consult a CPA or tax attorney about whether you qualify for the bona fide employer office exception. Maintain records of days worked in each location. Some taxpayers challenge COE assessments when they can demonstrate true business necessity for remote work.
