Remote Work Tax Tips
Verify your employer withholds for the correct state
Your employer should withhold income tax for your live state (where you physically work), not their state. If they're withholding the wrong state's taxes, update your W-4 / state withholding form.
Document employer-required remote work
If Illinois uses a convenience rule, having written documentation that remote work is required by your employer — not just a personal preference — can protect you from owing Illinois taxes.
Track days physically worked in the employer's state
Even as a remote worker, days you physically travel to Illinois for work are taxable by Illinois. Keep records and file a nonresident return if thresholds are exceeded.
Claim the resident state tax credit
If you end up paying taxes to both states, your live state (South Carolina) typically provides a credit for taxes paid to Illinois on the same income, preventing full double taxation.
Frequently Asked Questions
Do I owe state taxes in Illinois if I work remotely from South Carolina?
For fully remote work, you are physically present in SC, so SC has the primary right to tax your income. IL generally cannot tax you unless you are physically present there. If your employer withholds IL taxes, you can claim a credit on your SC return to avoid double taxation.
How much state tax do I pay as a remote worker in South Carolina employed by a Illinois company?
On a $100,000 salary: South Carolina state tax is $6,400, Illinois state tax is $4,950. With the Standard Remote Work — Live State Taxes Apply scenario, your effective state tax obligation is $6,400, leaving you with $72,336 in take-home pay.
What is the 'convenience of employer' rule?
Several states (New York, Connecticut, Delaware, Pennsylvania, Nebraska) use the 'convenience of employer' doctrine. If your employer is based in one of these states and you work from home for your own convenience — not because your employer requires it — the employer's state can tax your wages as if you worked there. This can result in paying income taxes to two states simultaneously, though your home state usually provides a partial credit.
What can I do to reduce my remote work tax burden?
Key strategies: (1) If your employer requires remote work in writing, document this to defeat convenience-of-employer claims. (2) Ensure your employer withholds taxes for your live state, not the work state — you'll avoid overpaying and waiting for a refund. (3) Track any days you physically work in the work state, as you'll owe that state taxes on those days. (4) Maximize pre-tax deductions (401k, HSA) to reduce taxable income in both states simultaneously.
