Live in Delaware, work in New Jersey
Without wage reciprocity, the work state may tax wages earned there. Your home state generally offers a limited credit for eligible tax paid on the same income. Filing requirements, credit limits and local taxes need a separate check.

Before you use this estimate
This model assumes a full-year resident of Delaware, ordinary employee wages and all workdays physically in New Jersey. Check exemption eligibility before treating a work-state amount of $0 as your own result. Withholding is a prepayment, not final tax liability. Other income, a move during the year, remote work and separate local taxes or credits can change the result.

This is the usual filing pattern, not a determination that you must file. Filing thresholds, age or dependent status, other income and withholding refunds can change which returns you need.
How this $100,000 estimate adds up
These steps follow the selected home, work state, salary and filing status. They reconcile the model's annual liability, not the amounts withheld from your paycheck.
| Step | New Jersey work state | Delaware home state |
|---|---|---|
| Tax before the modeled other-state credit | $4,180 | $5,259 |
| Modeled other-state credit subtracted | $0 | $4,180 |
| Tax after that credit | $4,180 | $1,079 |
Total: $4,180 + $1,079 = $5,259 a year. Amounts are rounded for display. Work-state wage exemptions, when applicable, are already reflected in the first row; they are not an other-state credit.
The modeled credit is applied in Delaware, the home state. Actual eligibility and credit limits require the state instructions. Included county components stay in these amounts; excluded local taxes and credits stay excluded. Federal income tax, payroll programs and refund eligibility are outside this reconciliation.
State tax at different salaries

| $75,000 | $2,596 | $1,013 | $3,609 | $3,609 |
| $100,000 | $4,180 | $1,079 | $5,259 | $5,259 |
| $150,000 | $7,365 | $1,194 | $8,559 | $8,559 |

What to do
- Ask your employer to withhold New Jersey tax. If Delaware's tax is higher, withhold the difference for Delaware too (or make estimated payments) to avoid an underpayment penalty.
- File the New Jersey nonresident return first, then claim the credit for taxes paid to another state on your Delaware resident return.
- Keep a record of the days you work in each state, especially if you sometimes work from home.
Working from home for a New Jersey employer
New Jersey has a "convenience of the employer" rule. Retaliatory rule enacted 2023, retroactive to Jan 1, 2023: applies to residents of convenience-rule states (NJ currently lists DE, NE, NY) working remotely for NJ employers. PA residents excluded due to reciprocity; CT residents handled separately.
Local income taxes
- Delaware: Wilmington levies a 1.25% earned income tax on residents and on nonresidents working in the city - relevant for PA, NJ, MD commuters.
- New Jersey: No local wage tax on employees (Newark's 1% payroll tax is employer-paid).
Frequently asked questions
Do I pay New Jersey income tax if I live in Delaware?
Yes. New Jersey taxes wages earned there by nonresidents. On $100,000 that's about $4,180.
Do I have to file taxes in both Delaware and New Jersey?
Usually yes: a nonresident return in New Jersey and a resident return in Delaware, where you claim a credit for the tax paid to New Jersey. File the New Jersey return first.
Will I be taxed twice?
The modeled state credit reduces overlap on eligible wages; separate local taxes or sourcing differences can still leave additional tax. Delaware credits the tax you pay New Jersey, so your total is about $5,259 on $100,000, compared with $5,259 if you also worked in Delaware. Local city or county taxes may still apply.
