Live in South Carolina, Work Remotely for a Delaware Employer: Who Taxes You?
Answer
Expect Delaware withholding despite the distance. Under Delaware's convenience-of-the-employer rule the location of your desk does not control; the reason you are at that desk does. Two returns follow — Delaware nonresident first, then the South Carolina resident return with the credit.

A handful of states refuse to accept the ordinary sourcing rule for their own employers' remote staff. Delaware is one of them, and its convenience-of-the-employer rule is the reason this page does not end with "only your home state taxes you".
Delaware sources a nonresident employee's remote workdays to Delaware when the employee works outside the state for their own convenience rather than because the employer requires it. Days worked outside Delaware at the employer's necessity are excluded.
The rule is not an administrative preference. Delaware applies it under 30 Del. C. §1124; Delaware Division of Revenue Technical Information Memorandum 2011-1, and the burden of showing that remote work is an employer necessity rather than an employee convenience falls on you and your employer, not on Delaware Division of Revenue.
A South Carolina resident taxed by another state on the same income claims the credit for taxes paid to other states on Form SC1040TC. The credit is capped at the South Carolina tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
Delaware also has a layer below the state one, and it is the layer that survives every agreement: Wilmington levies a city earned income tax on wages earned inside the city, collected by the city rather than the Division of Revenue.
What you file
- 1Nonresident return · DelawareForm PIT-NON
File the Delaware nonresident return FIRST — you need the Delaware tax figure before you can complete South Carolina.
- 2Resident return · South CarolinaForm SC1040TC
File a South Carolina resident return reporting all income, then claim the credit for tax paid to Delaware. The credit is capped at what South Carolina would have charged on that same income, so if Delaware taxes it at a higher rate the difference is not refunded.

Same two states, different situation
The withholding answer turns on how you are paid and where the work happens, not only on which two states are involved.
- W-2 commuter: South Carolina → DelawareBoth states — credit offsets the double tax
- 1099 contractor: South Carolina → DelawareHome state, plus the client state if you work there
- Moved mid-year: South Carolina → DelawareTwo part-year returns

Questions people actually ask
I live in South Carolina and work remotely for a Delaware employer. Which state do I pay?
Expect Delaware withholding despite the distance. Under Delaware's convenience-of-the-employer rule the location of your desk does not control; the reason you are at that desk does. Two returns follow — Delaware nonresident first, then the South Carolina resident return with the credit.
Which state should my employer be withholding for?
Both, potentially — and that is the problem. Delaware expects withholding because it claims the income, while South Carolina taxes you as a resident. Many employers withhold only for Delaware, which leaves a South Carolina balance due at filing unless you make estimated payments during the year.
Will I end up paying tax twice on the same income?
Not twice over, but you will pay the higher of the two rates. South Carolina gives residents a credit for tax paid to Delaware on the same income, claimed on Form SC1040TC. The credit is capped at the South Carolina tax on that income, so if Delaware taxes it more heavily the excess is not refunded by either state.
