Delaware uses a progressive state income tax system with rates ranging from 2.2% to 6.6%. Despite being a small state, Delaware is home to many corporations due to its business-friendly laws, and has no sales tax to offset its income tax.

What You'll See on Your Paystub
A Delaware worker's paystub includes both federal income tax withholding and state deductions:
| Deduction | Rate | Notes |
|---|---|---|
| Federal Income Tax | Varies | Based on W-4 and income |
| Social Security | 6.2% | Up to $181,200 wage base |
| Medicare | 1.45% | No wage limit |
| DE State Income Tax | 0% - 6.6% | Progressive based on income |
Delaware Standard Deduction
Delaware provides a standard deduction:
| Filing Status | Standard Deduction (2026) |
|---|---|
| Single | $3,250 |
| Married Filing Jointly | $6,500 |
Delaware's standard deduction is much lower than the federal amount. You may benefit from itemizing if you have significant deductions.
No Local Income Taxes
Delaware does not allow cities or municipalities to impose local income taxes. The state rate is the only income tax you'll pay in Delaware.
No Sales Tax Advantage
Delaware is one of only five states with no sales tax. While this doesn't directly affect your paystub, it increases your effective take-home purchasing power:
- No sales tax on any purchases
- Popular shopping destination for residents of neighboring states
- Outlet malls attract shoppers from PA, NJ, and MD
- Lower overall tax burden when considering consumption
When comparing Delaware to neighboring states, factor in that you'll pay no sales tax on purchases. This can offset some of the income tax burden.
Wilmington Area Workers
Wilmington is Delaware's largest city and economic center:
- Major financial services hub (credit card companies, banks)
- Many corporations incorporated in Delaware
- Chemical industry (DuPont heritage)
- Easy access to Philadelphia job market
Corporate Headquarters
Many major corporations are incorporated in Delaware due to business-friendly laws:
- Over 60% of Fortune 500 companies are Delaware corporations
- However, most headquarters and jobs are elsewhere
- Financial services companies do have significant Delaware operations
Dover and Southern Delaware
Central and southern Delaware have different employment characteristics:
- Dover is the state capital (state government jobs)
- Dover Air Force Base is a major employer
- Beach communities (Rehoboth, Lewes) have tourism-based employment
- Agriculture remains significant in southern counties
Cross-Border Workers
Delaware has no reciprocity agreements with neighboring states. If you live in one state and work in another:
- Live in DE, work in PA: File returns in both states; DE gives credit for PA taxes paid
- Live in DE, work in MD: File returns in both states; DE gives credit for MD taxes paid
- Live in DE, work in NJ: File returns in both states; DE gives credit for NJ taxes paid
- Live in PA, work in DE: File returns in both states; PA gives credit for DE taxes paid
Many Delaware residents commute to Philadelphia, and many Pennsylvania/Maryland residents work in Wilmington. You'll file returns in both states but receive credit to avoid double taxation.
Retirement Income
Delaware offers some tax benefits for retirees:
- Social Security benefits are fully exempt
- $12,500 exclusion for pension and eligible retirement income (under age 60)
- $12,500 exclusion for pension and eligible retirement income (age 60+)
- Military pension: qualifies for the exclusion
Delaware's retirement income exclusion is modest. Neighboring Pennsylvania fully exempts all retirement income, making it more attractive for retirees with significant pension or 401(k) income.
Military Personnel
Delaware has military considerations:
- Dover Air Force Base is a major installation
- Active duty pay follows residence-based rules
- Military retirement pay qualifies for the $12,500 exclusion
- No local taxes on any income

| Delaware | Progressive | 6.6% |
| Pennsylvania | Flat + Local | 3.07% + local |
