Who Must File a 2010 South Carolina Tax Return
The filing requirements for a South Carolina tax return depend on your residency status, age, and income. Understanding these rules is an important part of the tax filing since not everyone qualifies to submit a return. The following groups were required to file an income tax return for 2010.
1. Residents Under Age 65
- If you were required to submit one that included income taxable by South Carolina, you had to file a federal income tax return.
- You must also file a lawsuit if your employer withheld South Carolina income tax from your wages.
2. Residents Age 65 or Older
- Married couples filing jointly, where both spouses were age 65 or older, had to file if their gross income was greater than the federal filing requirement plus $30,000.
- You must file for all other filing statuses if your gross income exceeded the federal filing requirement plus $15,000.
- A filing was also required if South Carolina income tax was withheld from your pay.
3. Nonresidents and Part-Year Residents
- You were required to file if you earned South Carolina source income and your gross income was greater than the federal personal exemption amount.
- You also had to file if South Carolina tax was withheld from your wages.
South Carolina residents are taxed on their entire income regardless of where it was earned, unless specifically exempt under state tax laws. Nonresidents and part-year residents pay only on income earned within the state. Keeping track of your filing status and income level helps determine if you qualify to file and ensures the process is completed without mistakes that could delay a refund.

Step-by-Step Guide to Filing Your 2010 South Carolina Return
Filing a South Carolina tax return for 2010 is easier when you follow a clear sequence. The steps below walk you through the entire process from gathering tax information to choosing how to e-file or mail your forms. Each step is written for first-time filers and anyone returning after several years away from tax season.
Step 1: Gather your tax information and forms
- Collect W-2s from each employer, 1099s for interest, dividends, or contract work, and any schedules that show South Carolina source income.
- Keep records for retirement distributions, unemployment, and rental property if they apply to your income.
- Have your financial institution account and routing numbers ready if you want a refund by direct deposit, which is usually the fastest way to receive money.
- If you are missing data from the past, you can request transcripts from the IRS or contact payers listed on prior returns.
Step 2: Determine your filing status
- Choose the federal filing status that fits your situation, such as single, married filing jointly, married filing separately, head of household, or qualifying widow(er).
- Review how your filing status affects whether you qualify to file a South Carolina income tax return and how the state calculates your tax.
- Consider how dependents and family circumstances may change your tax laws exposure and potential deductions.
Step 3: Prepare your federal return first
- Complete your federal income tax return, as South Carolina begins with the federal adjusted gross income to calculate state tax.
- You may use software, including free options, to guide calculations and reduce effort and cost.
- Tax experts can provide guidance or audit support if you want expert help with complex returns.
Step 4: Start the SC1040 and enter identification details
- Enter your name, address, county code, Social Security number or ITIN, and your spouse’s information if applicable.
- Confirm that your filing status matches your federal return to avoid a mistake that could delay a refund.
- Decide whether to e-file through approved software for an efficient submission or to prepare a paper return that you can mail.
Step 5: Report your income
- Use your federal figures to report wages, tips, and other earned income on the SC1040.
- Residents report all income, while nonresidents and part-year residents report only South Carolina source income and complete Schedule NR.
- Include self-employment income, interest and dividends, capital gains, rental property income, and any other taxable amounts that apply to your return.
Step 6: Apply South Carolina deductions and adjustments
- Review state deductions such as the age 65 and older deduction, the retirement income deduction, and the deduction for children under age six if you qualify.
- Confirm whether state-specific additions or subtractions apply to your income so your calculations reflect South Carolina tax laws.
- Keep documentation that supports deductions because it helps answer questions from the Department of Revenue if the system flags an issue.
Step 7: Claim the credits you are eligible to receive
- When applicable, consider the tuition tax credit on Form I-319 and the credit for taxes paid to another state on Form SC1040TC.
- If you installed a qualifying solar energy system or operated a qualifying renewable energy manufacturing business in 2010, review the rules for those credits.
- Read the instructions carefully so you do not submit a claim you do not qualify to receive.
Step 8: Calculate tax, payments, and your refund, or the amount you owe
- Use the 2010 instructions to compute state income tax and compare it to withholding and estimated payments.
- If you are due a refund, choose direct deposit to your financial institution to get funds quickly and to reduce the chance of a mail delivery delay.
- If you owe, decide how to pay and include the SC1040-V payment voucher when you submit a paper return.
- Electronic Funds Withdrawal and approved card payments allow you to pay through the Department of Revenue site with clear date options.
Step 9: Attach required documents
- Attach readable copies of all W-2s and any 1099s that show South Carolina income so the Department can match your data.
- Include Schedule NR for nonresident filings and any schedules or forms that support credits and deductions.
- Attach a copy of your federal return when the instructions require it and include an approved extension form if you received one.
Step 10: Review, sign, and finalize your return
- Check names, Social Security numbers, math, and bank account entries to prevent processing errors that slow the process.
- Ensure both spouses sign a joint return because unsigned returns are considered incomplete.
- Confirm that the dates, totals, and calculations match the instructions so your return is ready to submit without last-minute changes.
Step 11: Submit your return by e-file or mail
- E-files are processed through approved software to reduce errors and speed up processing, which many customers prefer for efficiency.
- If you mail a paper return, use the correct address for refunds or returns with a balance due, and include the SC1040-V if you owe.
- Keep proof of mailing or the electronic confirmation to show when you file and submit payment.
Step 12: Keep records and track your status
- Please save a complete copy of your return, schedules, and payment confirmations for your records and future planning.
- Use the refund status tool on the Department of Revenue site or call the published phone numbers for updates if processing takes longer than expected.
- If you need support after filing, you can contact the Department for answers or ask tax experts for guidance on follow-up questions.
This sequence helps you prepare, complete, and submit an income tax return with fewer errors, less stress, and a better chance at the maximum refund you can receive. It also provides a simple process that works whether you decide to file independently with software or prefer expert help for extra assurance.
Common Mistakes to Avoid
Filing a South Carolina tax return for 2010 required careful attention to detail. Even small mistakes could delay your refund or cause the Department of Revenue to send your return for corrections. Below are the most common errors to watch for.
- Using the wrong forms. Always use the 2010 SC1040 and related schedules. Submitting a form from a different year will result in rejection.
- Entering incorrect or missing Social Security numbers. Check the numbers for yourself and your spouse if you are filing jointly.
- Forgetting to attach Schedule NR. This is required for nonresidents or part-year residents with South Carolina source income.
- Leaving out the SC1040-V payment voucher. If you owe taxes and do not include this form, your payment may not be processed correctly.
- Sending unsigned returns. A return is not valid unless signed. For joint returns, both spouses must sign.
- Not matching the written and numerical check amounts. Inconsistent amounts cause delays and may require resubmission.
Avoiding these mistakes helps ensure the process is efficient, reduces stress, and allows you to get your refund faster.
How to File Your 2010 Return
Taxpayers could choose between electronic filing and paper filing. Each option had its benefits, and understanding the process helps you decide the best method for your situation.
Electronic filing options
- Faster processing: Returns filed electronically were processed more quickly, and refunds could arrive in as little as 12 days with direct deposit.
- Special incentive for 2010: Taxpayers who filed electronically had until May 1, 2011, to pay balances due without penalty or interest. This did not apply to paper returns.
- Free File program: Qualifying taxpayers could file federal and state returns at no cost through approved software.
- Professional tax preparers: Many tax experts offered e-file services, making the process more efficient.
Paper filing
- Barcode advantage: Tax preparation software could print a 2-D barcode on paper returns. This allowed information to be scanned into the system, reducing data entry errors.
- Mailing addresses: Returns due a refund or showing no balance should be mailed to:
SC1040 Processing Center
P.O. Box 101100
Columbia, SC 29211-0100
Returns with a balance due should be mailed to:
Taxable Processing Center
P.O. Box 101105

Choosing the right filing method depends on whether you want to receive your refund quickly, how much effort you want to invest in the process, and whether you need expert help.

These phone numbers connect you to customer service representatives who can provide guidance and answer questions if your return requires review.

Do I need to file if I had no South Carolina income?
Generally, you do not need to file a tax return if you had no South Carolina income. However, if an employer withheld state taxes from your pay, filing may allow you to claim a refund. Reviewing your tax information and filing status will help determine if you qualify. This simple process can save money and ensure you follow the correct tax laws.
How do I amend my 2010 return?
To amend a South Carolina tax return for 2010, you must file Form SC1040X. You will likely need to update your state return if you also amended your federal income tax return with the IRS. You must include all schedules, forms, and deductions that changed. Submit the corrected return by mail, and ask tax experts for guidance to avoid a mistake.
Where do I mail my 2010 tax return?
If your return showed a refund or no tax due, you would mail it to the SC1040 Processing Center, P.O. Box 101100, Columbia, SC 29211-0100.

How do military members and spouses handle South Carolina taxes for 2010?
Military members remained South Carolina residents even when serving on orders outside the state. Under federal tax laws, the Military Spouses Residency Relief Act allowed some spouses to avoid paying income tax in South Carolina if they were present only to accompany the servicemember. Reviewing your filing status and earned income rules helps determine whether you qualify for an exemption, and expert help may be useful in preparing these forms.
Does South Carolina accept ITINs for 2010 returns?
Yes, in 2010, South Carolina accepted Individual Taxpayer Identification Numbers (ITINs) instead of Social Security numbers. This allowed individuals who could not obtain an SSN to file their income tax returns. To complete the process, you must prepare the same forms, include all income and deductions, and submit payment if you owe. Direct deposit for a refund was not available without a valid financial institution account.
