Direct Answer
Check your South Carolina tax refund status at the SC Department of Revenue’s MyDORWAY portal (mydorway.dor.sc.gov). You need your Social Security Number and the exact refund amount from your SC1040. E-filed returns process within up to 8 weeks from February 2, 2026 or your filing date, whichever is later. Social Security benefits and qualifying military retirement pay are fully excluded from South Carolina taxable income. TY 2025 filing deadline: October 15, 2026 (automatic extension — no form required). SC DOR extended the deadline pending OBBBA conformity legislation (HB 3368). Payment of at least 90% of tax owed remains due April 15, 2026. SC Form SC1040 starts from federal taxable income (Form 1040, Line 15). OBBBA deductions reduce federal taxable income and therefore enter SC’s starting figure. Because SC has not yet adopted those IRC provisions, an add-back is required for any OBBBA amounts claimed federally. Verify current guidance at dor.sc.gov.
Key Takeaways
How to Check Your South Carolina Tax Refund Status
Go to the SC Department of Revenue’s online portal at mydorway.dor.sc.gov and use the “Where’s My Refund” tool. No account login is required for the basic status check.
What You Need
- Your Social Security Number
- The exact refund amount shown on your SC1040
- The tax year you are checking (Tax Year 2025 for the 2026 filing season)
If you do not have your SC1040 available, retrieve it from your tax software before checking. An incorrect refund amount returns no result.
When to Check
For e-filed returns: allow at least 4 weeks before checking. E-file with direct deposit is the fastest refund method. For paper returns: allow at least 8 weeks from the date you mailed your return before checking.
If no status appears after those waiting periods, call the SC Department of Revenue at 1-844-898-8542 Monday through Friday, 8:30 a.m. to 5:00 p.m. ET. The local Columbia office line is 803-898-5000.
MyDORWAY Account Access
South Carolina taxpayers can create a MyDORWAY account to view filing history, make payments, submit documents, and track correspondence. Account creation requires identity verification. If you filed through commercial tax software, the guest refund status tool is the simpler option for a single lookup.
South Carolina Refund Processing Times
E-filed SC1040 returns with direct deposit are SC’s fastest refund path. SC DOR processes e-filed returns within up to 8 weeks from February 2, 2026 or the filing date, whichever is later. Returns filed before February 2 will not be processed before that date. Allow at least 4 weeks after the later of your filing date or February 2 before checking your status.
Paper returns take longer than the e-file window. SC DOR does not publish a fixed processing window for paper returns beyond “longer than 8 weeks.” Allow extended timelines for paper. Returns requiring documentation, identity verification, or income reconciliation take additional time beyond the standard window. SC DOR mails a written notice if your return is selected for review. Respond promptly to any SC DOR notice to avoid further delay.
Processing Time Summary
| Filing Method | Typical Processing Time | Speed |
|---|---|---|
| E-File + Direct Deposit | Up to 8 weeks (from Feb. 2 or filing date, whichever is later) | Fastest |
| E-File + Paper Check | Up to 8 weeks + mailing time | Fast |
| Paper Return + Direct Deposit | Extended; no fixed window published by SC DOR | Slower |
| Paper Return + Paper Check | Extended + mailing time | Slowest |
| Return Selected for Review | Additional weeks beyond standard | Slower |

South Carolina Income Tax Characteristics That Affect Your Refund
- Graduated rate structure (Act 61 of 2022 reform): South Carolina reduced its income tax brackets from six to three under Act 61 of 2022. The reformed structure applies rates of 0 percent, 3 percent, and a top rate declining annually toward a floor of 6 percent. For TY 2025, the top rate is 6.0 percent. The 0% rate applies to South Carolina taxable income up to $3,600. The 3% rate applies to income above $3,600 up to the upper bracket threshold. The 6.0% top rate applies above the upper bracket threshold. For South Carolina taxable income of $100,000 or more, the SC1040 Tax Tables calculate tax as: (income × 6%) − $642.
- Social Security and Railroad Retirement benefits (Line o): South Carolina fully excludes Social Security and Railroad Retirement benefits that are taxable on your federal return from South Carolina taxable income. This exclusion applies at all income levels with no phase-out. Enter the excluded amount on Line o of your SC1040.
- Military retirement pay (Line p): All military retirement pay that is included as taxable income is fully exempt from South Carolina income tax, regardless of the recipient’s age. A surviving spouse receiving military retirement income for a deceased spouse may also claim this exemption. Enter this amount on Line p of your SC1040.
- National Guard and Reserves retirement (Line v): Retirement income paid by the U.S. government for service in the National Guard or Reserves is exempt from South Carolina income tax. Use the military retirement exclusion worksheet in the SC1040 Instructions to calculate the amount, entered as part of Other Subtractions on Line v.
- Retirement income deduction: Taxpayers receiving income from a qualifying retirement account may deduct up to $3,000 of qualifying retirement income per year before reaching age 65, and up to $10,000 per year after reaching age 65. These are the confirmed TY 2025 figures per the official SC1040 Instructions.
- Age 65 and older income tax deduction (Line q): Beginning in the tax year a resident taxpayer reaches age 65, they may claim a deduction of $15,000 against any South Carolina income. If you claimed the Retirement Deduction or Military Retirement Deduction described above, you must subtract those amounts from the $15,000 to avoid double-counting, unless claiming as a surviving spouse. Enter this deduction on Line q of your SC1040. This is the confirmed TY 2025 figure per the official SC1040 Instructions.
- Standard deduction and personal exemptions: South Carolina allows taxpayers to deduct either the federal standard deduction amount (as reported on the federal return) or itemized deductions using SC Schedule A. SC also allows a dependent exemption of $4,930 per eligible dependent for TY 2025, covering both qualifying children and qualifying relatives.
- SC Earned Income Tax Credit (SC Code §12-6-3632): South Carolina offers a state-level earned income tax credit equal to 125% of the federal EITC amount for qualifying resident filers who also qualified for the federal EITC. For TY 2025, the SC EITC is nonrefundable. Returns claiming the SC EITC may be subject to eligibility review, which extends processing time.
- SC 529 Future Scholar deduction: South Carolina residents may deduct contributions to the SC Future Scholar 529 College Savings Plan from SC taxable income. The deduction applies to the account owner’s contributions. Verify the current maximum deduction and eligible plan details at dor.sc.gov.
- OBBBA federal deductions (tips, overtime, auto loan): South Carolina uses fixed-date IRC conformity. These OBBBA provisions may not be recognized under SC law. See the amber notice above for details.
Common South Carolina Refund Delay Reasons
- Income mismatch: SC DOR receives wage and income data from employers. If your SC1040 reports income that does not match employer-reported W-2 or 1099 data, your return is held for reconciliation. E-file transmits this data electronically and allows SC DOR to cross-reference more quickly than paper.
- Missing withholding documents on paper returns: Paper SC1040 returns require W-2s and 1099s to be attached. A paper return without supporting documents is held for documentation. E-filed returns transmit this data in the filing process and avoid this issue.
- Incorrect direct deposit information: A wrong routing number or account number causes the deposit to fail. SC DOR then issues a paper check, adding several weeks to the timeline. Verify your bank information before filing.
- Identity verification hold: Returns flagged by SC DOR’s fraud prevention system are held for identity verification. SC DOR mails a notice with instructions. Respond promptly and provide requested documentation to release the hold.
- SC EITC eligibility review: Returns claiming the South Carolina Earned Income Tax Credit are subject to eligibility review. Processing stops until the review is complete. Do not file an amended return while a review hold is active.
- Refund offset: Outstanding SC DOR tax liabilities, child support obligations, or other debts owed to the state can reduce or eliminate your refund. SC DOR mails a notice explaining the offset and any remaining refund amount.
- OBBBA modification required: If SC DOR issues guidance requiring a modification or addition for federal OBBBA deductions claimed on your federal return, returns that did not make the required SC adjustment may be held or corrected by SC DOR.
South Carolina Filing Season Timing
TY 2025 filing deadline: October 15, 2026. The SC Department of Revenue has automatically extended the filing due date for all 2025 South Carolina individual income tax returns to October 15, 2026. No form is required to receive this extension. The extension was announced on March 26, 2026, in connection with House Bill 3368, which would conform South Carolina’s tax code to the current Internal Revenue Code including the OBBBA. The SCDOR stated it will provide additional guidance once HB 3368 is enacted.
Payment deadline: April 15, 2026. The filing extension does not extend the payment deadline. Taxpayers who owe a balance must pay at least 90% of their 2025 South Carolina tax liability by April 15, 2026 to avoid a failure-to-pay penalty. Interest accrues on unpaid balances from April 15 forward. If you expect a refund, no action is required beyond filing by October 15.
South Carolina accepts returns beginning January 26, 2026, aligned with the start of the IRS e-file season. South Carolina participates in the IRS Modernized e-File (MeF) combined federal/state program. Major tax software supports SC e-file through the federal system. Taxpayers can also e-file directly through the MyDORWAY portal for eligible returns.
Part-year South Carolina residents file SC Form SC1040 and complete the part-year residency allocation. Income earned during the SC residency period is allocated to South Carolina. Income earned before or after the SC residency period is allocated using the appropriate part-year schedules.
Practitioner Note · Nausheen Shahid, LMN Tax Inc · 22+ Years Experience
"South Carolina’s appeal for retirees is real and often underestimated. The combination of full Social Security exclusion and full military retirement exemption means a retired service member with substantial military retirement income may owe little or no South Carolina income tax. We see clients relocate specifically because of this. The Act 61 rate reductions add to the picture, since the top rate is declining each year. The OBBBA conformity question is where I flag caution. South Carolina is a fixed-date conformity state. When Congress enacts a new IRC provision, South Carolina does not automatically adopt it. The state legislature has to pass a conformity bill. Clients who claimed OBBBA deductions on their federal return and simply carried that treatment into their SC1040 without checking SC guidance are at risk of an underreported income adjustment. The retirement income exclusion for filers age 65 and older is also frequently missed. Between the military exemption, the Social Security exclusion, and the age-based retirement deduction, SC1040 modifications for retirees can be substantial. Verify all three on every SC return for a client in that category."

Real-World South Carolina Refund Scenario
Laura is a 38-year-old nurse living in Columbia, South Carolina. Her 2025 W-2 shows $72,000 in wages from a South Carolina hospital. She contributed $6,000 to her employer’s pre-tax 401(k). Her federal AGI is $66,000. She takes the federal standard deduction on her federal return.
On her SC1040, Laura uses the federal standard deduction. After applying SC personal exemptions and any applicable SC modifications, her SC taxable income is reduced from her federal figure. She owes South Carolina income tax at the SC graduated rate structure. Her employer withheld South Carolina income tax throughout 2025 based on her estimated SC tax liability. She e-files her SC1040 with direct deposit in early February 2026.
Approximately 7 weeks after filing, Laura checks mydorway.dor.sc.gov using her SSN and the exact refund amount from her SC1040. Her status shows approved. Her direct deposit arrives within a week of the approval status. Her total time from e-filing to deposit is approximately 8 weeks, which is within the standard SC DOR e-file window.
This is a realistic example based on verified South Carolina tax rules. It is not a specific taxpayer case. Dollar amounts and timelines are illustrative.
When South Carolina Refund Tracking Does Not Apply
- Non-SC residents: file Form SC1040NR (non-resident return). Processing times and modification rules differ for non-resident returns. The refund status tool at mydorway.dor.sc.gov covers non-resident returns, but allow additional time when a credit for taxes paid to another state is claimed.
- Part-year SC residents: your SC refund reflects only the SC allocation of your income and withholding. Coordinate the SC return with your prior-state or destination-state return to ensure consistent income allocation across both returns.
- OBBBA deductions claimed federally: verify SC treatment before finalizing your SC1040. SC fixed-date conformity may require a modification. Using the federal OBBBA deduction amount directly on your SC1040 without confirming SC guidance could result in underreported SC income.
- SC EITC filers: additional review time applies. Do not file an amended return while a SC EITC review hold is active. Respond promptly to any SC DOR documentation request.
- Retired military filers: verify that the correct SC modification line is used to subtract qualifying military retirement pay. Omitting this subtraction results in overpaying SC income tax and a smaller-than-expected refund (or a balance due on income that should have been exempt).
- Amended SC returns: processed on a separate timeline from original returns. The standard refund status tool may not reflect amended return status. Allow additional processing time and call 1-844-898-8542 for amended return inquiries.
