South Carolina Taxes on Pensions IRAs and 401ks

South Carolina Taxes on Pensions IRAs and 401ks – South Carolina offers one of the most retiree-friendly tax environments in the U.S. when it comes to retirement income. While the state does impose income tax on most pensions, traditional IRA withdrawals, and 401(k) distributions, generous deductions and full exemptions for certain benefits make it attractive for retirees across the USA. This guide breaks down exactly how South Carolina taxes pensions, IRAs, and 401(k)s using the latest official rules from the South Carolina Department of Revenue (SCDOR) for tax years 2025 and 2026.

Whether you’re already living in the Palmetto State or planning a move, understanding these rules can help you maximize your retirement income and minimize your state tax bill.

South Carolina Retirement Tax Overview

South Carolina taxes retirement income as ordinary income but provides targeted subtractions that reduce or eliminate the state tax burden for most retirees. The state starts with your federal adjusted gross income (AGI) and then applies specific South Carolina subtractions for retirement accounts.

Key advantages include:

No tax on Social Security benefits.
Deductions of up to $10,000 on qualified retirement income for those 65 and older.
An additional $15,000 deduction (per qualifying taxpayer) for any income once you reach age 65.
Full exemption for all military retirement pay.

These benefits apply to pensions, traditional IRAs, 401(k)s, 403(b)s, 457 plans, and public employee retirement plans. Roth IRA qualified distributions remain completely tax-free at both federal and state levels.

No. South Carolina fully exempts Social Security benefits (and railroad retirement benefits taxed on your federal return) from state income tax. You simply subtract any federally taxed Social Security amount on Line o of the SC1040.

This makes South Carolina highly attractive compared to states that tax up to 85% of Social Security.

How Are Pensions Taxed in South Carolina?

Private, public, and government pensions are generally taxable in South Carolina if they are taxable on your federal return. However, you can claim the retirement income deduction on qualifying pension distributions.

Qualified pensions include those from:

Private employer plans
Federal, state, and local government pensions
Military retirement (see special rules below)

The deduction is limited to distributions that are not subject to the federal 10% early withdrawal penalty.

South Carolina Taxes on IRA Withdrawals

Traditional IRA withdrawals are taxed as ordinary income in South Carolina, just like federally. You qualify for the same retirement income deduction as pensions.

Roth IRA withdrawals:

Qualified distributions (after age 59½ and 5-year rule) are 100% tax-free in South Carolina.
Non-qualified distributions may be partially taxable.

The same age-based limits apply: up to $3,000 if under 65, or up to $10,000 if 65 or older.

Taxation of 401(k) and Similar Plan Distributions in South Carolina

401(k), 403(b), and 457 plan distributions follow the same rules as IRAs and pensions. They are taxable federally and in South Carolina unless offset by the retirement income deduction.

Rollover contributions or loans converted to distributions may trigger taxes and penalties federally, which carry over to your SC return. Early withdrawals before 59½ are subject to the 10% federal penalty plus state tax (minus any available deduction).

Special Rules for Military Retirement Pay

South Carolina is exceptionally generous with military retirement:

All military retirement income is fully deductible from South Carolina taxable income, regardless of your age (effective since tax year 2022).
Retirement pay from U.S. government service in the Reserves or National Guard is also exempt.
Surviving spouses may claim these benefits based on the deceased spouse’s age and service.

This full exemption often results in zero South Carolina tax on military pensions.

Age 65 and Older Deductions: Extra Savings for Seniors

Once you reach age 65 (or your spouse does), you unlock two powerful deductions on the SC1040:

Retirement Income Deduction — Up to $10,000 per person on qualified retirement income (pensions, IRAs, 401(k)s, etc.).
General Age 65+ Deduction — Up to $15,000 against any South Carolina taxable income. This is reduced by any retirement income deduction you claim (but not by surviving-spouse portions).

For married couples filing jointly where both are 65+, the combined effect can shelter $30,000+ of income. These are claimed on Lines p and q of the SC1040.

Under age 65, the retirement income deduction drops to $3,000 per person.

South Carolina State Income Tax Rates and Brackets for Retirees (2025–2026)

South Carolina uses a graduated income tax system. For tax year 2025, the top marginal rate is 6%. The brackets are approximately:

$0 – $3,560: 0%
$3,561 – $17,830: 3% (minus a small credit)
Over $17,830: 6% (minus a credit)

Many retirees with modest retirement income after deductions fall into the 0% or 3% bracket. The state also offers a standard deduction and personal exemptions that further reduce taxable income.

Note: Tax triggers may lower the top rate further in future years.

How to Report and Claim Deductions on Your South Carolina Tax Return?

Start with your federal Form 1040.
Complete the SC1040 and use the worksheets in the SC1040 instructions for Lines p (retirement deduction) and q (age 65+ deduction).
Attach Form 1099-R statements from your pension, IRA, or 401(k) administrator.
Use the military retirement exclusion worksheet if applicable.
File electronically via MyDORWAY for faster refunds.

The 2025 SC tax filing deadline has been automatically extended to October 15, 2026 for most filers.

Always keep records of your distributions and age eligibility.

Is South Carolina Tax-Friendly for Retirees?

Yes. South Carolina ranks among the most tax-friendly states for retirees because of:

Zero tax on Social Security.
Substantial deductions on pensions, IRAs, and 401(k)s.
Full military retirement exemption.
Low property taxes (among the lowest in the nation).
No estate or inheritance tax.

Retirees with retirement income under roughly $10,000–$15,000 (after federal taxes) often owe zero state income tax. Higher-income retirees still benefit from meaningful deductions compared to high-tax states.

Recent and Upcoming Changes to Watch

The retirement income deduction amounts ($3,000/$10,000) and age 65+ deduction ($15,000) are fully phased in and stable.
A 2025–2026 legislative bill proposes full deductibility of South Carolina state retirement plan income starting after 2026, but it is not yet law.
Federal contribution limits for 401(k)s and IRAs continue to rise (e.g., 401(k) limit $24,500 in 2026), which can help with tax planning.

Tax Planning Tips for Pensions, IRAs, and 401(k)s in South Carolina

Roth conversions: Consider converting traditional IRA/401(k) funds to Roth in low-income years to take advantage of future tax-free growth and withdrawals.
Timing withdrawals: Spread distributions to stay under deduction limits or lower brackets.
Coordinate with spouse: Maximize separate deductions on joint returns.
Military and public pensions: Double-check full exemptions.
Consult a professional: Work with a South Carolina tax advisor or use SCDOR resources, as individual situations vary.
Property tax relief: Seniors 65+ may also qualify for homestead exemptions—another big saver.
