South Carolina Tax Impact Calculator

Divorce in South Carolina changes your filing status, which increases your state income tax burden at rates up to 6% on income above $17,830. Your standard deduction drops from $30,000 (married filing jointly) to $15,000 (single) or approximately $22,500 (head of household). Post-2018 alimony is no longer deductible, property division triggers basis transfer issues, and the home sale exclusion decreases from $500,000 to $250,000.

Your filing status depends on your marital status on December 31 of the tax year. If your South Carolina divorce is finalized by that date, you file as Single or Head of Household — not Married Filing Jointly. Head of Household requires a qualifying dependent and provides a higher standard deduction ($22,500 vs. $15,000 for single). South Carolina requires the same filing status used on your federal return per S.C. Code § 12-6-5000.

For South Carolina divorces finalized after December 31, 2018, alimony is not tax-deductible for the payer and not taxable income for the recipient under federal TCJA rules. South Carolina conforms to federal tax law through S.C. Code § 12-6-40, so this treatment applies at both federal and state levels. Pre-2019 divorce agreements retain the old deduction/inclusion rules. Courts consider these tax consequences when setting alimony amounts under S.C. Code § 20-3-130.

Property transfers between spouses as part of a South Carolina divorce are tax-free under IRC § 1041(a) and exempt from the state deed recording fee under S.C. Code § 12-24-40. No gain or loss is recognized at the time of transfer. However, when the receiving spouse later sells the property, capital gains tax applies based on the original cost basis. South Carolina offers a 44% net capital gains deduction under § 12-6-1150, reducing the effective state tax rate on long-term gains to approximately 3.36%.

In South Carolina, the custodial parent — the parent with whom the child lives for more than half the year — claims the child as a dependent and receives the $2,000 child tax credit. The custodial parent can release the exemption to the noncustodial parent by signing IRS Form 8332. South Carolina follows federal rules, and the dependent exemption is worth $4,930 per qualifying child for state tax purposes. This also determines eligibility for Head of Household filing status.

Retirement account transfers through a Qualified Domestic Relations Order (QDRO) in South Carolina divorce are not taxed at the time of transfer and avoid the 10% early withdrawal penalty under IRC § 72(t). When the receiving spouse eventually takes distributions, those withdrawals are taxed as ordinary income at South Carolina rates up to 6%. Without a proper QDRO, early distributions face both income tax and a 10% federal penalty. South Carolina residents age 65 and older can deduct up to $15,000 in retirement income.

Married couples filing jointly in South Carolina can exclude up to $500,000 in capital gains from a home sale if both meet the 2-year ownership and use test. After divorce, the exclusion drops to $250,000 per individual under IRC § 121. South Carolina's 44% capital gains deduction under § 12-6-1150 reduces the state tax on any gain exceeding the exclusion. Selling before the divorce is finalized may preserve the larger $500,000 exclusion if you file a joint return for that tax year.

Innocent spouse relief protects you from tax liability caused by your ex-spouse's errors or fraud on a joint return filed during the marriage. You can request relief through IRS Form 8857 under IRC § 6015. South Carolina recognizes innocent spouse relief because the state conforms to the Internal Revenue Code under S.C. Code § 12-6-40. You must file within two years of the IRS's first collection attempt and demonstrate you had no knowledge of the understatement.
