                                                   INSTRUCTIONS
Filing requirements: If you owe an Income Tax liability of $100 or more on your SC1040 or SC1041, you must prepay 
your tax through withholding or with Estimated Tax payments. 
 
Use this form to determine if you paid enough Income Tax during the year. If you did not pay enough, you may owe a 
penalty based on the amount of your underpayment. 
 
You may be charged a penalty if: 
   •   you did not pay enough Estimated Tax. 
   •   you did not make your payments for the required amount by the due date. 
   •   you did not pay at least 90% of the total tax due. 
 
How to calculate your underpayment:       The underpayment of any installment is the difference between the amount of 
your required installment and any payments you made by the due date of the installment. Payments are applied to any 
prior underpayment before being applied to the current installment. Income Tax withheld from your salary, pension, or 
winnings are considered payments of Estimated Tax in equal installments on the four installment dates, unless you prove 
otherwise. 
 
Period of underpayment:  The penalty is applied to the number of days that the installment was not paid. Calculate the 
period of the underpayment by counting the number of days after the due date of the installment through the date of 
payment or the end of the rate period (12/31/22 or 4/15/23), whichever is earlier.  
 
If you fail to pay your Estimated Income Tax due earlier in the year, you will not be relieved of your penalty, even if you 
paid your 2022 Estimated Tax liability by January 15, 2023 or filed and paid the balance on your 2022 Income Tax Return 
by January 31, 2023. 
 
If you file your return and pay the tax due by January 31, 2023, you will have no penalty for the installment due January 
15, 2023 and the periods of underpayment for earlier installments will end on January 15, 2023.  
 
Exceptions to the penalty: 
You will not have to pay the penalty if:  
   1.  your prior year tax liability was $0 for a full 12 months, or  
   2.  the total tax on your 2022 return minus the amount of tax you paid through withholding is less than $100. 
       (Complete line 1 through line 6 to determine if the total tax is less than $100.) 
 
Farmers and fishermen: You will not have to pay a penalty if: 
   1.  your gross income from farming and fishing is at least two-thirds (66.67%) of your annual gross income from all 
       sources for 2021 or 2022 AND 
   2.  you filed the SC1040, Individual Income Tax Return, and paid the entire tax due by March 1 following the end of 
       the tax year. If March 1 falls on a weekend, the due date is the next business day. 
 
If you meet both 1 and 2, enter  Fin the exception box on SC1040, line 33. Attach the SC2210 to your tax return. 
If you meet 1 but not 2, complete the federal 2210F for South Carolina purposes. Write For South Carolina Purposes on 
the top of the completed form and attach it to your Income Tax return. 
 
Annualized Income Installment Method: If your income varied during the year, you may be able to lower the amount of 
your required installment by using the Annualized Income Method. Complete Schedule AI of the federal 2210 for South 
Carolina purposes. On the SC2210, line 9, write Annualized to the left of the line to indicate use of this method. Write For 
South Carolina Purposes    on the top of the completed federal Schedule AI and attach to your return. Enter   as theA
exception code on the SC1040, line 33. 
 
Waiver of penalty: If you have an underpayment on line 16, all or part of the penalty for that underpayment may be 
waived if any of the following applies: 
   1.  An underpayment was due to a casualty, disaster, or other unusual circumstance and it would be inequitable to 
       impose the penalty. 
   2.  In 2021 or 2022, you retired after age 62 or became disabled and your underpayment was due to reasonable 
       cause. 
   3.  The Estimated Income Tax penalty is attributed to personal service income earned in another state on which 
       Income Tax due the other state was withheld.
