How This Calculator Works
Calculation methodology and assumptions
Your marginal tax rate is the rate on your last dollar earned. Your effective rate is total tax ÷ total income — always lower than marginal. State tax is computed using Delaware's actual tax brackets, both for the dollar amount owed and for the marginal rate (the rate of whichever bracket contains your taxable income). Delaware has progressive brackets up to 6.6%, so your effective state rate will be lower than your marginal bracket unless your entire income falls in the top bracket.
How to Use This Tax Comparison Calculator
- 1
Enter your annual income
Input your gross annual income (before taxes). This should include salary, bonuses, and other taxable income. The calculator compares your total state + federal tax burden.
- 2
Review the tax breakdown
The calculator shows how Delaware's income tax, property tax, and sales tax combine to create your total tax burden — and how that compares to national averages.
- 3
Compare with other states
Use the related state calculators to compare your total tax burden in different states. This is especially useful if you're considering a move or remote work relocation.
Example Calculation
How does Delaware's tax burden compare for a typical household?
Consider a household earning $85,000/year that owns a $412,000 home (Delaware's median) and spends about $30,000/year on taxable purchases. Federal income tax (2026 brackets) plus FICA comes to roughly $16,373. Delaware's progressive income tax (up to 6.6%) adds about $4,594. Property tax at 0.54% adds $2,225/year, and sales tax at 0% on taxable spending adds roughly $0/year.
Result: Total estimated tax burden: approximately $23,191/year, or about 27.3% of gross income (24.7% from income taxes and FICA alone). The total effective tax rate varies dramatically by state — no-income-tax states can run 10+ percentage points lower than high-tax states at the same income, a difference worth thousands of dollars a year.
What Affects Your Results
Income Tax Structure
States use flat rates, progressive brackets, or no income tax at all. Progressive states tax higher incomes at higher rates — your effective rate may be much lower than the top marginal rate.
Property Tax Rate
Property taxes are the largest tax for many homeowners. Rates range from 0.32% (Hawaii) to 2.23% (New Jersey), creating $10K+ differences on the same-priced home.
Sales Tax
Combined state + local sales tax rates range from 0% (Oregon, Montana) to 9.5%+ (Louisiana, Tennessee). This disproportionately affects lower-income households.
Deductions & Credits
Some states offer generous standard deductions, earned income credits, or child tax credits that significantly reduce effective rates. Others tax from dollar one.
Tips for Delaware Residents
- Don't just compare income tax rates. States with no income tax often have higher property taxes or sales taxes to compensate. Look at the total tax burden.
- Consider the cost of living alongside taxes. A state with lower taxes but 40% higher housing costs may not actually leave you better off financially.
- If you're self-employed, state taxes matter even more because you pay both the employee and employer portions of FICA. Some states also levy additional self-employment taxes.
- Remote workers should understand their tax obligations. Some states tax based on where you live, others where your employer is located, and some have reciprocity agreements.
- Use the cross-state calculators on this site to model your specific scenario in multiple states before making a relocation decision.

Our editorial standardsFrequently Asked Questions
What is the difference between marginal and effective tax rate?
Your marginal rate is the tax percentage on your next dollar of income (your highest bracket). Your effective rate is total taxes paid divided by total income. For example, with $100,000 income and $18,000 in total taxes, your effective rate is 18%, even if your marginal bracket is 24%.
What are Delaware's income tax brackets?
Delaware uses progressive brackets with rates from 0% to 6.6%.
