Social Security Privacy Act Disclosure
It is mandatory that you provide your Social Security Number on this tax form if you are an individual
taxpayer. 42 U.S.C. 405(c)(2)(C)(i) permits a state to use an individual’s Social Security Number as means
of identification in administration of any tax. SC Regulation 117-201 mandates that any person required
to make a return to the SCDOR must provide identifying numbers, as prescribed, for securing proper
identification. Your Social Security Number is used for identification purposes.
Individual Taxpayer Identification Number (ITIN)
If you are a nonresident or resident alien and cannot get an SSN, contact the IRS to apply for an
Individual Taxpayer Identification Number (ITIN) for the purpose of filing Income Tax returns. South
Carolina will accept this number in place of an SSN to process your Individual Income Tax returns. For
more information, contact the IRS at 1-800-829-1040 or visit irs.gov. We cannot accept your return for
processing without complete SSNs or ITINs.

Checkboxes

should have been filed. Complete the SCH AMD, Amended Return Schedule, and submit it with
your amended SC1040. Your amended return cannot be processed without the SCH AMD.
2.	 If you are a nonresident for the entire year or a part-year resident electing to file as a
nonresident, check the appropriate box and attach your Schedule NR to the completed SC1040.
Do not submit the Schedule NR separately.
3.	 If you are filing a composite return for a partnership or S Corporation, check the appropriate box.
See the I-348, Composite Filing Instructions, available at dor.sc.gov/forms for more information
on filing a composite return. Do not check the box if you are an individual.
4.	 If you filed a federal or state extension, check the appropriate box.
5.	 If you served in a Military Combat Zone during the filing period, check the appropriate box and
enter the combat zone.

Line Instructions
Round all amounts to the nearest whole dollar.

Federal Taxable Income
Line 1: Federal Taxable Income
Enter your taxable income from your federal form. If your federal taxable income is zero or less, enter
zero here and enter your negative amount on line r.
STOP! Nonresident/Part-year filers must complete the Schedule NR and go to line 5. See the Schedule
NR instructions, available at dor.sc.gov/forms.

Additions to Federal Taxable Income
Enter all numbers on line a through line e as positive numbers even if they are negative numbers on
the federal return. Line a through line e are adjustments which must be added to your federal taxable
income to determine your South Carolina taxable income. Line 2 is the total of these additions.
Line a: State tax addback
If you itemized your deductions on your federal Income Tax return and deducted state and local Income
Tax or general Sales Tax, you may be required to add back all or part of this amount to your federal
taxable income when computing your South Carolina taxable income.
Federal law limits your total deduction for state and local Income, Sales, and Property Taxes to a
combined total deduction of $10,000 ($5,000 if Married Filing Separately). You can’t deduct any state
or local taxes paid above this amount.
In determining the state tax addback for a taxpayer whose tax deduction is limited to $10,000, you
may first apply real or personal Property Taxes reported on federal Schedule A, lines 5b and 5c before
applying state and local Income Taxes or general Sales Taxes reported on federal Schedule A, line 5a.
The state tax addback required for South Carolina is the lesser of your:
a.	 itemized deductions in excess of the standard deduction that would have been allowed if you
had used the standard deduction for federal Income Tax purposes;
b.	 state and local Income Taxes or general Sales Taxes from your federal 1040, Schedule A, line 5a;
or
c.	 the $10,000 federal tax deduction limit less deductible Property Taxes.
Use the worksheet below to compute the state tax addback on the SC1040. Do not submit this
worksheet with your return. Keep it with your tax records.

SCDOR | SC1040 Instructions

●	 Taxpayers who claim credits such as the Community Development Credit (TC-14), the Industry

Qualified catastrophe expenses are expenses paid or incurred because of a major disaster as
declared by the Governor.
●	 A business must add back any amount paid for services performed by an unauthorized alien if
the amount is $600 or more a year.
Depending on how a particular item was reported or deducted, the following may be additions or
subtractions.

SCDOR | SC1040 Instructions

Subtractions From Federal Taxable Income
Enter all numbers on line f through line w as positive numbers even if they are negative numbers on
the federal return.
Line f through line w are adjustments which are subtracted from your federal taxable income to
determine your South Carolina taxable income.
Line f: State tax refund
If you included your state tax refund on your federal 1040, enter that amount on this line.
Line g: Total and permanent disability retirement income
If disability retirement income was taxed on your federal Income Tax return and you are totally and
permanently disabled, you may be able to deduct this income from your South Carolina taxable
income.
You must be totally and permanently disabled, unable to be substantially gainfully employed, receiving
income from a disability retirement plan, and eligible for the homestead exemption under SC Code
Section 12-37-250. Attach a copy of the physician’s statement establishing that you are totally and
permanently disabled.
The deduction is limited to payments received from retirement plans. Third-party sick pay reported
on a W-2 does not qualify for the total and permanent disability retirement deduction.
If you deduct total and permanent disability retirement income on this line, do not include that income
in your qualified retirement income in the worksheets for line p-1 or line p-2.
A surviving spouse may take a disability retirement deduction for amounts received in the year the
disabled spouse died. In following years, a surviving spouse is eligible for the retirement deduction on
line p but not the disability deduction.
Line h: Out-of-state income/gain
Enter:
●	 income from out-of-state rental property
●	 income from a business located outside South Carolina, or
●	 gain from real property located in another state.
Enter the amount as reported on your federal return. Check the appropriate box to indicate the type of

Line i: Net capital gain deduction
Net capital gains included in taxable income are reduced by 44% for South Carolina Income Tax
purposes.
Net capital gain means the excess of the net long-term capital gain for the tax year over the net shortterm capital loss for the tax year. The South Carolina holding period for long-term capital gains is the
same as the federal holding period. Income received from installment sales and capital gain distribution
qualifies for this deduction if the more than one year holding period has been met. Multiply the net
capital gain by 44% and enter the result.

SCDOR | SC1040 Instructions

Line p-4 through line p-6: Military retirement deduction
Beginning with tax year 2022, individuals may deduct all military retirement income included in their
South Carolina taxable income. Reduce the retirement deduction (line p-1 and line p-2) and the age 65
and older deduction (line q-1 and line q-2) by the amount of military retirement deduction taken.
Military retirement income means taxable income received by the taxpayer or the taxpayer’s surviving
spouse from a qualified military retirement plan. Income that is subject to a penalty for premature
distribution does not qualify as military retirement income. For a surviving spouse, military retirement
income includes a retirement benefit plan and dependent indemnity compensation received due to the
deceased spouse’s military service.
Retirement benefits received for service in the National Guard or Reserves due to inactive time are
subtracted on line v and are not included in taxable income. Do not include these amounts in the
deduction on line p.
Line p-4: Include military retirement income related to the taxpayer’s military service.
Line p-5: Include military retirement income related to the spouse’s military service.
Line p-6: Include military retirement income received on behalf of a deceased spouse. Apply the
deduction in the same manner that it was applied to the deceased spouse.
The surviving spouse military retirement deduction is in addition to any retirement deductions claimed
on the taxpayer’s own retirement income.
If you are claiming the surviving spouse military retirement deduction for more than one deceased
spouse, calculate the deduction separately for each deceased spouse. Add the surviving spouse military
retirement deductions and enter the total on line p-6. Attach a statement showing the date of birth for
each deceased spouse and the separate calculation for each deduction.
Line q: Age 65 and older deduction
Beginning in the tax year a resident taxpayer reaches age 65, they are entitled to a deduction of
$15,000 against any South Carolina income.
Line q-1 applies to the taxpayer whose name appears first on the return.
Line q-2 applies to the spouse whose name appears second on the return.
Reduce the age 65 and older deduction claimed on line q-1 and line q-2 by:
●	 any individual retirement deduction claimed on line p-1 and line p-2, and
●	 any military retirement deduction claimed on line p-4 and line p-5
Claiming a surviving spouse retirement deduction on line p-3 or line p-6 does not reduce the age 65
and older deduction for a taxpayer on line q-1 or line q-2.

Assume for all examples that taxpayers have income to qualify for the age 65 and older deduction in
addition to the retirement deductions.
Example 1: A taxpayer age 65 or older has no military or other sourced retirement income on line p-1
or line p-4. The taxpayer is eligible for a deduction of $15,000 on line q-1.
Example 2: A taxpayer age 65 or older has no military retirement income but has other sourced
retirement of $14,000. The taxpayer is allowed a deduction of $10,000 on line p-1 and a deduction of
$5,000 on line q-1.
Example 3: A taxpayer age 65 or older has military retirement income of $13,000 and is allowed a
deduction on line p-4 of $13,000. The taxpayer is allowed a deduction of $2,000 on line q-1. The
maximum allowed deduction for 2023 is $15,000.
Example 4: A taxpayer age 65 or older has military retirement income of $36,000 and no other earned
income. The taxpayer is eligible for a military retirement deduction of $36,000 on line p-4. The taxpayer
is not allowed an additional amount on line q-1.
Example 5: A taxpayer age 65 or older has military retirement income of $16,000 and other sourced
retirement income of $8,000. The taxpayer is allowed a deduction on line p-4 of $16,000. The taxpayer
is not allowed an additional amount on line p-1 or line q-1.
For more information about retirement deductions and the age 65 and older deduction, refer to SC
Revenue Ruling #22-11, available at dor.sc.gov/policy.
Line r: Negative amount of federal taxable income
Because the South Carolina return begins with your federal taxable income, it is important that you get
the benefit of the negative amount from the taxable income line of the federal return. On the SC1040,
start with zero on line 1. Do not enter a negative amount. On line r of the SC1040, enter the negative
amount from the taxable income line of the federal return. Enter as a positive number.
Line s: Subsistence allowance
Police and all commissioned law enforcement officers paid by South Carolina municipal, county, or state
governments or the federal government, full-time firefighters, and full-time emergency medical service
personnel are entitled to a subsistence allowance of $8 per regular workday. Your employer should
provide you with the number of work days.
Line t: Dependents under 6 years of age
A deduction is allowed for each dependent claimed on your federal Income Tax return who had not
reached the age of 6 by December 31 of the tax year. Birth dates and SSNs are required. See worksheet
below.

Line u: Consumer protection services
An individual may deduct the costs of a monthly or annual contract or subscription for identity theft
protection and resolution services. The deduction is only for individuals who filed a return with the
SCDOR for a tax year between 1998 and 2012 or whose Personal Identifiable Information (PII) was
included on another’s return. An individual who deducted the same actual costs as a business expense
may not claim the deduction.
The deduction is limited to:
●	 $300 for an individual taxpayer
●	 $1,000 for a married filing jointly return
●	 $1,000 for a return claiming dependents
Identity theft protection includes products and services designed to prevent an incident of identity
fraud or identity theft. It protects against the disclosure of your PII (for example, your SSN) by
preventing a third party from using unauthorized access to your PII to obtain financial resources or
other products, benefits, or services.
Identity theft resolution services include products and services designed to assist persons whose PII
was obtained by a third party. This minimizes the effects of the identity fraud or identity theft incident
and restores the person’s identity to its pre-theft status.
Line v: Other subtractions from income
Attach an explanation of your entry on this line. Some examples of items which may be subtracted on
this line are:
●	 You may deduct 100% of any contributions made to a Palmetto ABLE Account Expense Fund,
subject to program limitations, between January 1, 2023 and December 31, 2023. For more
information, visit treasurer.sc.gov.
●	 South Carolina does not recognize bonus depreciation in IRC Section 168(k). With or without
bonus depreciation, the depreciable life of the property is the same for federal and state
purposes. For the tax year the property is placed in service, a taxpayer must add back, on line e
of the SC1040, the difference between the depreciation deduction allowed for federal purposes
and the deduction that would have been allowed without bonus depreciation. The South
Carolina adjusted basis will then be greater than the federal adjusted basis. For all other years of
the depreciable life of the property, an additional depreciation deduction is available for South
Carolina purposes.
●	 South Carolina net operating loss that is larger than the federal amount is a subtraction. The
same loss can only be deducted once. Attach your own worksheet or keep with your tax records.
No carryback losses are allowed.
●	 Legislators within a 50-mile radius of the State House are allowed to subtract travel expenses.

●	 If you have adopted a special needs child, you may subtract $2,000 per year per child as long as
the adopted child qualifies as a dependent on your federal return.
A special needs child is:
1.	 a person under the age of 18 at the time of adoption
2.	 a dependent of a public or private non-profit adoption agency
3.	 legally free for adoption

Attach a copy of the letter you received at the time of adoption from the SC Department of
Social Services which certified the person as a special needs child.
●	 Subtract amounts contributed to a Catastrophe Savings Account and interest income earned by
the account.
If your legal residence is insured against hurricane, rising floodwaters, or other catastrophic
windstorm event damage, you are allowed to contribute:
■	 $2,000 if the qualified deductible is $1,000 or less
■	 twice the qualified deductible if it is between $1,000 and $7,500
■	 $15,000 if the qualified deductible is more than $7,500
If your legal residence is not insured against hurricane, rising floodwaters, or other catastrophic
windstorm event damage, the limit is $250,000 or the value of your legal residence, whichever is
less.
●	 If you are eligible for the Preceptor Credit on the TC-62 and you served additional rotations
that exceeded the credit limit for the tax year, you may be eligible for a deduction equal to
the amount that the credit would have been for the additional rotations. Refer to the TC-62,
available at dor.sc.gov/forms, for information on calculating the deduction. For additional
information, see SC Revenue Ruling #20-2, available at dor.sc.gov/policy.

taxpayer reached age 70, or
●	 the withdrawal followed the death of the individual who set up the account or the surviving
spouse.

Nonrefundable Credits
Line 11: Child and Dependent Care Credit
For a full-year resident, the credit is calculated at 7% of the federal child and dependent care expense.
If you are a part-year resident or nonresident, you are not eligible for this credit if you are a resident of
a state that does not offer a credit for child and dependent care expense to nonresidents of that state.
If you are an eligible part-year resident or nonresident, calculate the credit at 7% of the prorated federal
expenses using your proration percentage from the Schedule NR.
The maximum credit allowed is $210 for one child or $420 for two or more children.
You cannot claim this credit if your filing status is Married Filing Separately.
Example A: Full-year resident
Federal child care expense from the federal 2441 is $2,000
$2,000 x .07 = $140 (allowable credit)
Example B: Part-year resident or nonresident
Federal child care expense from the federal 2441 is $2,000, and the proration percent from line 45 of
Schedule NR is 30%.
$2,000 x .30 = $600 x .07 = $42 (allowable credit)
Line 12: Two Wage Earner Credit
This credit is available to a married couple filing jointly when both spouses have earned income taxed
to South Carolina. This credit is not allowed on returns with a filing status of Single, Married Filing
Separately, or Head of Household.
The multiplier used in computing the Two Wage Earner Credit increases by $3,333 each year beginning
in 2018, until fully phased-in for tax year 2023. For 2023, the credit is computed at .007 of the lesser
of $50,000 or the South Carolina qualified earned income of the spouse with the lower South Carolina
qualified earned income for the taxable year.
Use your South Carolina qualified earned income to calculate the credit. Compute your South Carolina
qualified earned income by subtracting certain adjustments reported on your federal 1040 from your
South Carolina earned income.
Adjustments to subtract are:
●	 deductible part of self-employment tax
●	 self-employment SEP, simple and qualified plans

15

SCDOR | SC1040 Instructions

●	 self-employment health insurance deduction
●	 IRA deduction
●	 repayment of sub-pay
South Carolina earned income is generally income you receive from services you provide. Compute the
earned income for you and your spouse separately.
Earned income includes
wages
salaries
tips
commissions
sub-pay
self-employment income
business income or loss
partnership income or loss
farm income or loss

Earned income does not include
gambling winnings
bingo winnings
interest
dividends
Social Security benefits
IRA distributions
retirement plan or annuity benefits
deferred compensation
any amount your spouse paid you

Example: A taxpayer earned a salary taxed to South Carolina of $40,000. The taxpayer’s qualified
earned income is $40,000. Their spouse earned wages of $17,000 taxed to South Carolina and had an
IRA deduction of $1,000. The spouse’s qualified earned income is $16,000 ($17,000 - $1,000). The credit
is based on the spouse’s qualified earned income, because it is the lesser of the two. The credit is $112
($16,000 x .007).

●	 from out-of-state catalog companies
●	 from home shopping networks
●	 when visiting another state
The tax rate for the Use Tax is the same as the Sales Tax. The rate is determined by where the tangible
personal property will be used, stored, or consumed, regardless of where the sale takes place. For more
information and updated tax rates, visit dor.sc.gov/tax/use.
You have three options for reporting and paying Use Tax:

Line 30: Refund
If line 29 is larger than line 24, go to line 31. Otherwise, subtract line 29 from line 24 and enter the

Add line 25 and line 29.
Line 32: Late filing and late payment penalties and interest
If you calculated failure to file or failure to pay penalties and interest, enter in the appropriate blanks
and put the total of both on line 32.
A failure to file penalty is charged for failing to file a tax return on or before its due date, considering
any extension of time for filing. The penalty is 5% of the tax amount if the failure is for not more
than one month, with an additional 5% for each additional month or fraction of a month the failure
continues, not to exceed 25% in total.
A failure to pay penalty is charged for failing to pay the tax on any return on or before its due date. The
penalty is 0.5% of the tax if the failure is for not more than one month, with an additional 0.5% for each
additional month or fraction of a month the failure continues, not to exceed 25% in total.
Any unpaid portion of the final tax due will accrue interest at the prevailing federal rates. This amount is
computed from the original due date of the tax return to the date of the payment.
Find a Penalty and Interest Calculator on our free online tax portal, MyDORWAY, at
dor.sc.gov/calculator.
Line 33: Underpayment of Estimated Tax penalty
You may owe a penalty for underpayment if you did not pay in the lesser of 90% of your tax liability for
2023 or 100% of your liability for 2022 in four equal amounts by the required dates.
If your adjusted gross income is $150,000 or more, the 100% rule is modified to be 110% of the tax
shown on your 2022 Income Tax return. Refer to the SC2210, available at dor.sc.gov/forms, to calculate
any penalty that may be due.
Exceptions to the underpayment of Estimated Tax:
●	 Enter an A in the box if you completed federal Schedule AI-Annualized Income Installment
Method for South Carolina purposes when determining the amount to enter on line 33.
●	 Enter an F in the box if you are a farmer or fisherman who receives at least two-thirds of your
gross income for the year from farming and fishing and you pay your tax due by March 1, 2024.
●	 Enter a W if you are requesting a waiver of your penalty for any other reason. See the SC2210
instructions, available at dor.sc.gov/forms, for information on what qualifies for a waiver of
penalty.
