Need more time to file your South Carolina taxes?

You're not alone!

Whether you're waiting on a W-2 or need extra time, a tax extension can be a lifesaver. But here's the thing: while you get more time to file your return, you still have to pay any taxes due by April 15th.

Don't let the fine print get you down—keep reading to learn how a South Carolina tax extension can save you from penalties and get you back in tax shape!

What is a Tax Return Extension?

A tax extension gives you extra time—usually 6 months—to file your individual income tax return. But remember, the extension gives you more time to file, not more time to pay.

Any taxes due must be paid by April 15th, or you'll face penalties and interest.

A tax extension will prevent late filing penalties for individuals who need more time to get their tax documents in order or are waiting on additional tax forms.

However, you must pay at least 90% of your estimated tax liability to avoid financial penalties.

Do I Need to File a South Carolina Tax Extension if I Filed a Federal Extension?

Sometimes, filing for a federal extension will automatically extend your South Carolina filing deadline. If no taxes are due in South Carolina, you do not need to submit Form SC4868, as South Carolina will accept your federal extension. However, if you owe state taxes, you must file SC4868 and pay the balance by the original deadline.

What Happens if I Don't Pay My Taxes on Time?

If you don't pay at least 90% of your estimated tax liability by April 15th, South Carolina imposes a penalty of 0.5% per month on the unpaid balance, in addition to interest charges. These penalties can quickly add up, so paying as much as possible by the original deadline.

Example: Estimating Your Payment

Let's say your total tax liability for the year is $8,000. To avoid penalties, you must pay at least $7,200 (90%) by April 15th. If you've already paid $6,000 through withholdings, you must make an additional payment of $1,200 when filing Form SC4868.

Penalties for Late Filing and Payment

  • Late Filing Penalty: 5% per month (up to a maximum of 25%) on the unpaid balance.
  • Late Payment Penalty: 0.5% per month on the unpaid tax, starting after April 15.
  • Interest: Charged on any unpaid tax at the federal rate, compounded daily.

Individual Income Tax by County

The following counties contribute the highest state income tax revenue, with Charleston County leading at over $725 million. These counties are urbanized areas with larger populations and higher average income levels, which explains their substantial contributions to the state's tax revenue.

On the other hand, counties like Hampton and Marlboro contribute the least to the state's tax revenue. These are smaller, more rural counties with lower population density and economic activity, resulting in significantly lower tax liabilities.

This data is important because it shows regional economic disparities. Knowing which counties contribute more to state tax revenue will help with financial planning and highlight areas that need economic development. For individual taxpayers, this will also show how their county compares to others and the local economy.
