Delaware Taxes: What We Need to Know

Understanding Delaware’s tax landscape is crucial for both employers and employees. From federal and state withholdings to insurance contributions, Delaware’s tax system impacts your paycheck in several ways.

Here’s a breakdown of the key components:

Federal, State, and Local Tax Withholdings

The residents of the First State face a tiered tax system. While federal income tax applies nationwide, the state income tax ranges from 2.2% to 6.6%, depending on your earnings. Unlike some states, Delaware doesn’t impose a general sales tax.

FICA and State Insurance Taxes

The Federal Insurance Contributions Act (FICA) taxes fund Social Security and Medicare programs. These are split between employers and employees, each contributing 7.65% of wages (6.2% for Social Security and 1.45% for Medicare). Delaware also requires employers to pay State Unemployment Insurance (SUI) tax. For 2026, the SUI wage base has increased to $14,500 (up from $12,500 in 2025), and the new employer rate stands at 1.8%. Experienced employer rates for 2025 ranged from 0.6% to 6.5%; 2026 rates will be published by the Delaware Department of Labor.

Pre-Tax Deductions

Smart financial planning involves two components, the pre-tax era and the post-tax era. Pre-tax era includes deductions such as medical insurance premiums and 401(k) contributions, which helps reduce your taxable income. Note that the Delaware EARNS (Expanding Access for Retirement and Necessary Savings) program — a state-mandated Roth IRA — became fully active in 2024, and penalty enforcement for non-compliant employers begins in 2026. Employers with five or more employees who do not offer a qualifying retirement plan face fines of $250 per eligible employee per year, up to a maximum of $5,000 annually.

Here’s a quick reference table for Delaware’s key tax rates:

Notable 2026 legislative updates: The supplemental Operations and Technology Assessment of 0.2%, paid by all Delaware employers, continues to fund the Department of Labor’s technology needs — a policy established under House Bill 433 for 2025 and carried into 2026. Additionally, Delaware EARNS penalty enforcement is now active in 2026, making retirement plan compliance a key payroll consideration for employers with five or more staff.

Whether you’re a long-time Delaware resident or considering a move to the state, knowing how these taxes affect your paycheck helps you make smarter financial decisions.

Median Household Income in Delaware

Understanding Delaware’s median household income provides a crucial context for the state’s tax structure and overall economic health. Let’s examine how it has evolved with time.

Here’s a table showing Delaware’s median household income over the past few decades, updated with the most recent available figures (U.S. Census Bureau / Federal Reserve data, inflation-adjusted to 2024 dollars):

Delaware’s median household income reached $84,954 in nominal 2024 dollars according to the U.S. Census Bureau’s American Community Survey (5-year estimates), placing Delaware approximately 5% above the national median. Despite some year-to-year fluctuation, the long-run trend shows meaningful real income growth for Delaware households.

When we consider these income levels in relation to Delaware’s tax structure, we can see why the state maintains a graduated income tax system. This approach aims to balance the tax burden across different income levels, with higher earners paying a larger share while still incentivising the economy.
