Freelance and 1099 taxes in Delaware
Net self-employment earnings in Delaware flow into the same 7-bracket structure (top rate 6.60%) that applies to wages — but unlike a W-2 employee, nothing is withheld for you, so the state's share accrues silently until a payment is due. Delaware's state standard deduction is $3,250 for single filers and $6,500 for married filing jointly in 2026. Wilmington levies a 1.25% earned-income tax on residents and non-residents working in the city.
Self-employed and 1099 filers in Delaware owe the 15.3% federal self-employment tax (12.4% Social Security up to the wage base, 2.9% Medicare with no cap) on net earnings, plus federal income tax and Delaware state tax up to 6.60%. On $100,000 of gross 1099 income with $15,000 of deductible business expenses, the estimated total tax burden in Delaware is about $24,541.77, leaving roughly $60,458.23 take-home (effective rate 28.87%).
The IRS expects quarterly estimated payments (Form 1040-ES) once you owe $1,000 or more for the year, and Delaware Division of Revenue runs a parallel state estimated-payment schedule.

What is the self-employment tax rate in Delaware?
Self-employment tax in Delaware (and everywhere in the US) is 15.3% on the first portion of net earnings: 12.4% Social Security (capped at the annual wage base) plus 2.9% Medicare (no cap, plus 0.9% additional Medicare above $200,000 single). It is calculated on net earnings × 92.35% to mirror the FICA tax employees would pay. Delaware does not levy a separate self-employment tax, but state income tax up to 6.60% still applies to net business income.
Do Delaware freelancers need to make quarterly estimated tax payments?
Yes. If you expect to owe at least $1,000 in federal tax after withholding, the IRS requires quarterly estimated payments (April, June, September, January). Delaware also requires quarterly state estimated payments to avoid underpayment penalties; due dates generally mirror the federal schedule.
Is Delaware a good state for freelancers and self-employed workers?
Delaware is workable for freelancers, though state income tax up to 6.60% reduces take-home compared with no-income-tax states. Other factors matter: cost of living, sales tax on services (varies by state), health insurance market, and local business license costs. Delaware's $390,000 median home price is also part of the calculus.
What deductions can Delaware freelancers claim?
Common federal deductions for Delaware self-employed filers include: home-office (simplified $5/sqft or actual expense method), health-insurance premium deduction (above-the-line), self-employment tax deduction (half of SE tax), retirement contributions (SEP-IRA, Solo 401(k)), business mileage (70¢/mile for 2026), startup costs (up to $5,000 first year), and the Qualified Business Income (QBI) deduction (up to 20% of qualified income, subject to thresholds). Delaware generally conforms to most federal business deductions for state purposes, with state-specific add-backs.
Delaware vs Maryland for freelancers: which has lower taxes?
On $100,000 gross 1099 income with $15,000 expenses, estimated total tax is $24,541.77 in Delaware vs $23,945.36 in Maryland. Maryland comes out lower by about $596.41 per year for this scenario.
