Income Thresholds for South Carolina Income Taxes in 2020

Understanding the income thresholds for the South Carolina tax return 2020 is essential for residents and nonresidents who must comply with state taxes. The South Carolina Department of Revenue sets clear rules that align with federal standards but include specific adjustments for age, filing status, and residency. Meeting these requirements ensures your state return is complete, accurate, and submitted on time to avoid penalties, interest, or delays.

• Threshold for Single Residents Age 65 and Over: For the current tax year, South Carolina residents aged 65+ must file if their federal gross income meets federal filing requirements plus $15,000. This income tax threshold applies to wages, business earnings, and other taxable income sources. Tax filing at this level ensures accurate calculation of state taxes owed or a potential refund. Review your income tax return carefully before you submit or mail it.
  
  
• Threshold for Married Couples Age 65 and Over Filing Jointly: Married couples 65+ must file a South Carolina income tax return if their federal gross income meets federal filing requirements plus $30,000. This rule covers combined wages, retirement income, and other payments received during the year. Filing ensures compliance with South Carolina income taxes and helps qualify for any available deductions. Tax professionals can assist in preparing your return to meet these requirements.
  
  
• Differences Based on Age, Filing Status, and Residency: Income tax thresholds vary for residents, nonresidents, and part-year residents based on age and filing status. For example, younger taxpayers follow only the federal gross income requirement without the additional threshold. SC residents must file if their income meets or exceeds the standard for their category, even if taxes were already paid. The South Carolina Department provides instructions and forms to help you complete the process online or by mail.

By knowing these specific income thresholds, taxpayers can take advantage of timely filing to avoid penalties and interest while securing any refund owed. Staying informed ensures your tax return meets South Carolina law, supports accurate revenue collection, and helps maintain your tax records for the current and future tax years.

Types of Income Considered for South Carolina Income Tax Filing Purposes

South Carolina considers several income categories when determining if you must file a 2020 state income tax return. Each type has specific rules that can affect your filing status and tax amount.

• Wages, Salaries, and Tips: These include all compensation from employment, whether paid in cash, direct deposit, or reported tips. Employers typically report these amounts on a W-2 form.
  
  
• Self-Employment or Business Income: Profits from freelance work, sole proprietorships, or partnerships are taxable, even without a formal business license. This income is usually reported on the federal Schedule C.
  
  
• Rental Income from South Carolina Properties: Earnings from renting homes, apartments, or commercial property in South Carolina are taxable to the state. This applies whether you are a resident or nonresident.
  
  
• Interest, Dividends, and Retirement Distributions: Taxable interest from bank accounts, corporate dividends, and certain pension or IRA withdrawals must be included. Some retirement income may qualify for state deductions.
  
  
• Capital Gains and Investment Income: Profits from selling stocks, bonds, or property in South Carolina are considered taxable. Short- and long-term gains follow federal reporting rules with state adjustments.

Special Rules for Different Individual Income Taxpayer Groups

South Carolina’s 2020 income tax rules included specific provisions for certain taxpayer groups, affecting how income was taxed and reported.

• Senior Citizens and Additional Exemptions: Seniors aged 65 and older could qualify for higher income thresholds before filing became necessary. They were also eligible for additional personal exemptions that reduced taxable income. Retirement income exclusions further lowered the amount subject to state tax.
  
  
• Military Personnel and Retirement Pay Exclusions: Active-duty military pay earned outside South Carolina was exempt from state income tax. Military retirement pay enjoyed a partial exclusion, with higher limits for older retirees. Residency rules determined whether other service-related income was taxable.
  
  
• Students and Dependents with Earned Income: Dependents with part-time or seasonal jobs had to file if income exceeded specific limits. Even small amounts of taxable income could trigger filing if withholding occurred. Federal dependency status impacted South Carolina’s filing requirements for these taxpayers.
  
  
• Small Business Owners and Sole Proprietors: All business income earned in South Carolina was taxable, regardless of business size. Sole proprietors had to report both active earnings and passive business-related income. Deductions for expenses were allowed but required thorough recordkeeping for compliance.

By understanding these special rules, taxpayers in these groups could file accurately and take advantage of legal tax benefits.

Key Due Date and Extensions for 2020

The 2020 South Carolina tax filing timeline changed significantly due to COVID-19, with specific adjustments for deadlines and extensions. Below are the key points every taxpayer should know.

• Original 2020 Filing Deadline: South Carolina’s original individual income tax deadline matched the federal date of April 15, 2021, for the 2020 tax year. This alignment helped ensure consistency between federal and state filing requirements. Taxpayers planning to submit early still had the option to file before April to expedite refunds.
  
  
• COVID-19 Extension Adjustments: Due to pandemic disruptions, South Carolina extended the 2020 deadline to May 17, 2021, without penalty or interest. This automatic extension matched the IRS relief period for federal returns. The extension applies to both filing and payment obligations for eligible taxpayers.
  
  
• Special Electronic Filing Extensions: Taxpayers filing electronically could request an additional extension for paperwork submission until October 15, 2021. However, all taxes owed still had to be paid by May 17 to avoid penalties. This electronic extension only covered filing, not the payment deadline.
  
  
• Penalties and Interest for Late Filing: Filing after the extended due date without an approved extension triggered a penalty of 5% per month on unpaid taxes. Interest accrued daily on balances owed until full payment was received. Prompt action minimized both charges and potential collection enforcement.

These 2020 rules could help South Carolina taxpayers plan, stay compliant, and avoid unnecessary costs.

Common Mistakes When Determining South Carolina Tax Return Filing Requirements

Many South Carolina taxpayers make filing mistakes that lead to penalties or missed refunds.
Here are the most frequent errors to avoid when determining if you need to file for 2020:

• Overlooking Part-Year Residency Income: Moving into or out of South Carolina during the year still requires reporting income earned while a resident.
  
  
• Misreporting Retirement or Military Pay Exemptions: Some retirement and military incomes have partial or complete state exemptions, but incorrect reporting can trigger audits or lost benefits.
  
  
• Not including South Carolina–Source Income for Nonresidents: Earning wages, rental income, or business profits from South Carolina sources creates a filing obligation, even without residency.
  
  
• Confusing Federal and State Income Thresholds: State filing requirements may differ from federal limits, particularly for seniors or joint filers, leading to mistaken non-filing.

By understanding these specific pitfalls, you can ensure accurate filing and remain compliant with South Carolina’s 2020 tax rules.

How to Track Your Refund or Balance Due

Tracking your South Carolina refund or balance due requires knowing the exact tools, timelines, and payment methods available.

• Using the “Where’s My Refund” Tool: The South Carolina Department of Revenue offers an online tracker to monitor your refund status. You must provide your Social Security number, filing status, and exact refund amount. This tool updates daily, helping you see progress without calling the tax office.
  
  
• Processing Timelines for E-File vs. Paper Returns: When filed early in the season, e-filed returns are usually processed within three weeks. Due to manual handling and verification steps, paper returns may take six to eight weeks.
  Filing electronically with direct deposit is the fastest option to receive your refund.
  
  
• Refund Payment Options: Direct deposit sends your refund directly to your bank account for quicker access. Paper checks are mailed to your address, which can take additional time. Selecting direct deposit during filing minimizes delays and avoids potential check delivery issues.

Understanding these tools, timelines, and options allows you to track your refund confidently and plan your finances effectively.

How to Make a Payment

Paying your South Carolina taxes involves several secure options, each with its own steps and deadlines.

• Using MyDORWAY Online Portal: Access MyDORWAY at dor.sc.gov/pay to make payments by ACH debit, credit card, or debit card. ACH debit payments are free, while card payments incur a processing fee.
  You can also set up approved payment plans through the portal for qualifying balances.
  
  
• Paying by Check: Make checks payable to “South Carolina Department of Revenue” and write your SSN or FEIN on the memo line. Include a completed payment voucher from your return or MyDORWAY printout—mail payments to the address listed on the voucher or return instructions for your tax type.
  
  
• Payment Deadlines and Penalties: For 2020, payments were due by the original or extended filing deadline, even if you filed later. Late payments accrue a penalty of 0.5% per month and interest based on the state’s current rate.
  Missing deadlines can also trigger collection actions for unpaid balances.

By choosing the most convenient method and meeting deadlines, you can avoid unnecessary penalties and keep your tax account in good standing.

FAQs

How do I know if my income is taxable in South Carolina?

Your income is taxable in South Carolina if you are a resident with taxable or nonresident earnings from South Carolina sources. This includes wages, business profits, rental income, and investment gains. The South Carolina Department of Revenue (SCDOR) provides guidance that mirrors federal rules but with state-specific adjustments. Reviewing SCDOR’s filing requirements and your federal adjusted gross income will help determine whether you must file a return for 2020.

Are Social Security benefits included in South Carolina's taxable income?

South Carolina does not tax Social Security benefits, regardless of your age or income level. These benefits are excluded from your state taxable income calculations. However, other forms of retirement income, like pensions or distributions from retirement accounts, may be partially taxable. When preparing your return, it’s essential to distinguish Social Security from other retirement income. Check SCDOR’s official retirement income deduction rules for details on exemptions and applicable limits.

Do I need to file if I only have part-time or seasonal income?

You may need to file if your part-time or seasonal earnings meet South Carolina’s income thresholds. Filing is required for residents meeting federal standards with taxable state income, regardless of whether the work was short-term. If state tax was withheld from your paycheck, filing could allow you to claim a refund. Always compare your income against the SCDOR’s filing requirement tables to determine your obligation for 2020.

What if I had income in another state and in South Carolina in 2020?

If you earned income in multiple states, you may need to file returns in each applicable state. South Carolina residents must report all income from any source, then claim a credit for taxes paid to other states. Part-year residents or nonresidents with South Carolina income must file using the appropriate SCDOR forms. Carefully review both states’ filing rules to avoid double taxation and ensure proper credits are applied.

Is unemployment income taxable in South Carolina for 2020?

Yes, South Carolina follows federal treatment and taxes unemployment benefits received in 2020. You must include the total amount of unemployment compensation in your state taxable income. This applied even if part of your unemployment was due to COVID-19 job losses. You may owe tax when filing if South Carolina tax was not withheld from your benefits. Check your Form 1099-G and SCDOR’s 2020 instructions to ensure accurate reporting.
