Frequently Asked Questions
Is alimony taxable in South Carolina?
For divorces finalized after December 31, 2018, alimony is not taxable to the recipient and not deductible by the payer. Pre-2019 divorces follow the old rules (deductible/taxable).
Does the old tax rule still apply if my divorce was before 2019?
Yes — unless your agreement has been modified to specifically adopt the new tax rules.
What happens to alimony taxes if I modify my pre-2019 agreement?
The old rules continue unless the modification explicitly states that the new (post-2018) rules apply.
How Alimony and Taxes Work After Divorce in SC
When you’re negotiating alimony in a South Carolina divorce, the dollar amount on paper is only part of the story. The tax treatment of alimony determines how much that support is actually worth — and the rules changed dramatically in recent years.
Many people are still confused about whether alimony is taxable in South Carolina, whether it can be deducted, and how the 2018 tax law change affects their specific situation. In this guide — part of our complete guide to alimony in South Carolina — we clear up the confusion.
Key Takeaway: For divorces finalized after December 31, 2018, alimony is neither taxable to the recipient nor deductible by the payer. For pre-2019 divorces, the old rules may still apply.
The Big Change: Tax Cuts and Jobs Act of 2017
The Tax Cuts and Jobs Act (TCJA), signed into law in December 2017, fundamentally changed how alimony is treated for federal tax purposes — and since South Carolina follows federal tax treatment, these changes apply to SC divorces as well.
Before 2019 (Old Rules)
For divorce or separation agreements executed before January 1, 2019:
- Payer: Could deduct alimony payments from their taxable income (an “above-the-line” deduction)
- Recipient: Had to report alimony as taxable income
This system created a built-in tax advantage: because the payer was usually in a higher tax bracket, the total tax burden on alimony dollars was lower. This often meant the payer could afford to pay more, and the recipient received more overall.
After 2018 (New Rules)
For divorce or separation agreements executed after December 31, 2018:
- Payer: Cannot deduct alimony payments
- Recipient: Does not report alimony as taxable income
Under the new rules, alimony is treated like any other after-tax payment. The payer pays alimony from their after-tax income, and the recipient receives it tax-free.
Which Rules Apply to Your Divorce?
The key date is when your divorce or separation agreement was executed — not when you separated, not when you filed, and not when you started making payments.
| Divorce/Agreement Executed | Payer Deducts? | Recipient Pays Tax? |
|---|---|---|
| Before January 1, 2019 | ✅ Yes | ✅ Yes |
| After December 31, 2018 | ❌ No | ❌ No |
What About Modifications to Pre-2019 Agreements?
If you modify a pre-2019 divorce agreement, the old tax rules generally continue to apply — unless the modification specifically states that the new (post-2018) tax rules should apply.
This is an important detail. If you’re considering modifying your alimony order, make sure you and your attorney address the tax treatment explicitly in any new agreement.
How Tax Treatment Affects Alimony Negotiations
The tax change has a real impact on divorce negotiations. Here’s why:
Under the Old Rules (Pre-2019)
The tax deduction for the payer created a “tax subsidy” for alimony. Because the government effectively shared the cost through the tax deduction, both parties could come out ahead:
- A payer in the 32% tax bracket who paid $3,000/month in alimony effectively spent only about $2,040 after the tax deduction.
- A recipient in the 22% bracket who received $3,000/month kept about $2,340 after taxes.
Under the New Rules (Post-2018)
Without the tax deduction, the payer bears the full cost, and the recipient receives the full amount:
- The payer who pays $3,000/month actually spends $3,000 — no tax benefit.
- The recipient receives $3,000 tax-free.
This means that in negotiations, payers may push for lower alimony amounts because they can no longer offset the cost with a tax deduction. Conversely, recipients may accept slightly lower amounts because they keep every dollar tax-free.
Understanding these dynamics is essential. The court considers tax consequences as one of the factors in how alimony is calculated in SC, and your attorney should be able to model the after-tax impact of different alimony scenarios.
South Carolina State Tax Treatment
South Carolina follows federal tax treatment for alimony. This means:
- Post-2018 divorces: No SC state tax deduction for payer; no SC state income tax for recipient on alimony.
- Pre-2019 divorces: SC state income tax follows the federal deduction/inclusion rules.
There are no additional South Carolina-specific tax complications for alimony — the state conforms to federal law on this issue.
Tax Planning Tips for Your Alimony Case
Regardless of which tax rules apply to your situation, here are some practical tips:
- Know your effective date. The date your divorce or separation agreement is executed determines which tax rules apply. Don’t assume — verify.
- Model the after-tax cost. Before agreeing to an alimony amount, calculate what it actually costs (or is worth) after taxes using current rates
- Consider the total financial picture. Alimony is just one piece — coordinate with your attorney and a financial advisor or CPA to consider property division, retirement accounts, and other tax implications together.
- Be careful with modifications. If you have a pre-2019 agreement, think carefully before agreeing to a modification that explicitly adopts the new tax rules — it could cost you.
- Keep good records. Whether you’re paying or receiving alimony, maintain clear records of all payments for tax documentation purposes.
Different Alimony Types and Tax Implications
The tax rules apply to all types of alimony — periodic, lump-sum, rehabilitative, and reimbursement — as long as the payments meet the IRS definition of “alimony.” Key requirements include:
- Payments are made in cash (or cash equivalents like checks or transfers)
- Payments are made under a divorce or separation instrument
- The spouses do not file a joint tax return
- The spouses are not members of the same household when the payment is made
- There is no liability to continue payments after the recipient’s death
If payments don’t meet these requirements, they may be classified as property settlement or child support — which have different tax treatment.
