South Carolina Powerball Tax Calculator: How Much Would You Keep?
Estimate a South Carolina Powerball cash payout after federal and State taxes using South Carolina's completely revised 2026 income-tax system. See the 5.21% Lottery withholding, final State liability and estimated take-home separately.
South Carolina Powerball Tax Changed Significantly in 2026
South Carolina's old income-tax structure is no longer the correct model for a 2026 jackpot. Act 110 created a new two-rate system: 1.99% below $30,000 of South Carolina taxable income and 5.21% above that threshold, with a $966 subtraction built into the upper-band formula.
New top State rate
For tax year 2026, South Carolina's maximum individual rate is 5.21%, replacing the older rate structure that many Lottery calculators still show.
Prize withholding follows it
State law requires withholding on cash prizes of $500 or more at a percentage equal to the maximum individual tax rate for resident and nonresident individuals.
New State deduction
South Carolina decoupled from the federal standard/itemized deduction and introduced its own income-adjusted deduction for 2026.
Older “6% South Carolina” jackpot pages are now stale for tax year 2026. The enacted 2026 maximum individual rate is 5.21%. Any automatic future reduction in the law begins with tax year 2027, not 2026.

South Carolina Powerball Withholding in 2026
South Carolina law requires a person distributing a cash prize or winnings of $500 or more to a resident or nonresident individual to withhold a percentage equal to the State's maximum individual income-tax rate. For tax year 2026, that maximum rate is 5.21%.
| Tax layer | Current withholding | Threshold | How MLL treats it |
|---|---|---|---|
| Federal | 24% | Qualifying Lottery proceeds above $5,000 | Advance withholding only; final federal tax is calculated progressively. |
| South Carolina | 5.21% | Cash prizes/winnings of $500 or more | Advance State payment compared with the 2026 South Carolina tax calculation. |
On a giant jackpot, the 5.21% State withholding is already very close to the final simplified South Carolina tax. That is because the prize is far above the SCIAD phaseout ceiling and the upper State formula is 5.21% of taxable income minus $966.
The 2026 South Carolina Tax Formula Is Now Much Simpler
South Carolina's enacted 2026 structure contains just two tax formulas. Taxable income below $30,000 is taxed at 1.99%. Once taxable income reaches $30,000, the tax is 5.21% of taxable income minus $966.
2026 South Carolina formula
- $0 to under $30,000: 1.99% of South Carolina taxable income.
- $30,000 and above: 5.21% of taxable income minus $966.
- Federal AGI is now the starting point for the State return.
- Federal standard and itemized deductions are no longer adopted for this State calculation.
- The new SCIAD is applied before the State tax formula.
The $966 is not an extra tax. It is subtracted in the upper-band formula so the two-rate system joins correctly at $30,000.
What Happens to the New SCIAD After a Powerball Win?
The new South Carolina Income Adjusted Deduction starts at $15,000 for Single/MFS, $22,500 for Head of Household and $30,000 for MFJ, but it shrinks as federal AGI rises. A Powerball jackpot is far above every full phaseout point, so the deduction normally becomes $0 in the winning year.
Single / MFS
Starts at $15,000, begins phasing out above $40,000 federal AGI and is fully gone once the phaseout fraction reaches one at $95,000.
Head of Household
Starts at $22,500, begins phasing out above $60,000 and reaches zero by $142,500 federal AGI.
Married Filing Jointly
Starts at $30,000, begins phasing out above $80,000 and reaches zero by $190,000 federal AGI.
This is why the jackpot calculation is relatively clean. At Powerball-level income, SCIAD is $0, leaving the 5.21%-minus-$966 State formula as the dominant calculation.
What If a Nonresident Wins Powerball With a South Carolina Ticket?
South Carolina's withholding statute expressly covers prizes paid to residents and nonresidents. South Carolina's nonresident return instructions also place prizes and gambling winnings from South Carolina sources in the South Carolina income column.
The calculator computes South Carolina tax with the prize and subtracts the tax on entered other income alone.
The prize is treated as South Carolina-source income. The 2026 nonresident SCIAD is prorated by South Carolina AGI divided by federal AGI, while home-state tax or credits remain outside this page.
At jackpot income, the deduction issue mostly disappears. Because the all-source federal AGI is already far beyond the SCIAD phaseout ceiling, both resident and nonresident jackpot calculations generally have a $0 SCIAD before considering other State-specific adjustments.
South Carolina Powerball Winners Can Keep Their Name Private

180-day claim period

South Carolina Powerball Cash Option vs. Annuity

One-time cash option

30 annual installments
