South Carolina does not tax most pension income, but the rules depend on what type of pension you receive and when you started collecting it.

South Carolina exempts most private pensions, government pensions, and military pensions from state income tax. This is one of the most pension-friendly tax policies in the country. However, the exemption does not apply to all pension income equally — some retirees pay tax on part of their pension, and a small group pays tax on all of it.

The key factor is when you were born. If you were born before January 1, 1922, your entire pension is exempt. If you were born on or after that date, you get a partial exemption that phases out as your total income rises. Understanding which category you fall into and what your total income is determines whether you owe state tax on your pension.

Key Takeaways

  • Retirees born before January 1, 1922, pay no state income tax on any pension income, regardless of how much they receive.
  • Retirees born on or after January 1, 1922, receive a $10,000 annual exemption on pension income, but this exemption phases out once total income exceeds $30,000 for single filers or $40,000 for married couples filing jointly.
  • Military pensions follow the same rules as civilian pensions — birth date determines the exemption amount, not military service status.
  • The exemption applies only to pensions; Social Security, 401(k) withdrawals, and investment income are taxed under different rules.

Who Gets the Full Exemption and Who Pays Partial Tax

South Carolina divides retirees into two groups based on birth date. The first group — anyone born before January 1, 1922 — is now extremely small, but those individuals pay zero state income tax on pension income of any amount. This is a permanent, complete exemption.

Everyone else born on or after January 1, 1922, receives a $10,000 annual exemption on pension income. This means the first $10,000 of your pension each year is not taxed by South Carolina. If your pension is $15,000 per year, you pay tax only on $5,000. If your pension is $8,000 per year, none of it is taxed.

The exemption shrinks once your total income crosses a threshold. For single filers, the $10,000 exemption begins to phase out when total income exceeds $30,000. For married couples filing jointly, it phases out at $40,000. As income rises above these thresholds, the exemption decreases by $1 for every $1 of income above the limit, until it reaches zero.

How Income Thresholds Reduce Your Exemption

The phase-out works as a direct reduction. If you are single and your total income is $35,000, you are $5,000 over the $30,000 threshold. Your $10,000 exemption shrinks to $5,000. If your total income is $40,000 or more, your exemption disappears entirely and your entire pension becomes taxable.

Total income includes your pension, Social Security, wages, interest, dividends, capital gains, and any other income South Carolina taxes. This is important because retirees often think only about pension income when calculating the threshold, but Social Security counts too. A retiree with a $20,000 pension and $15,000 in Social Security has $35,000 total income, which puts them $5,000 over the single threshold.

For married couples, the calculation uses joint income. If one spouse has a $25,000 pension and the other has $18,000 in Social Security, joint income is $43,000, which is $3,000 over the $40,000 threshold. The couple's combined exemption shrinks from $10,000 to $7,000.

Military Pensions and Government Employee Pensions

Military pensions receive the same treatment as civilian pensions under South Carolina law. A retired military officer born after January 1, 1922, gets the $10,000 exemption and the same phase-out rules as a retired teacher or factory worker. Military service does not create a separate exemption or a larger deduction.

Government employee pensions — from state agencies, local governments, school districts, or public universities — also follow the standard rules. A South Carolina state employee pension, a county employee pension, and a municipal pension all may have access to for the $10,000 exemption and phase out at the same income thresholds as private pensions.

Federal pensions, including those from the Federal Employees Retirement System (FERS) and the Civil Service Retirement System (CSRS), are treated the same way. The exemption applies regardless of whether your pension comes from a private employer, a state agency, a local government, or the federal government.

What Income Does Not Get the Pension Exemption

The $10,000 exemption applies only to pension income. Social Security benefits are taxed under a separate South Carolina rule — they are generally not taxed, but some retirees do pay tax on a portion of their benefits depending on total income. The pension exemption does not protect Social Security from taxation.

Withdrawals from 401(k)s, IRAs, and other retirement accounts are taxed as regular income and do not receive the pension exemption. If you are taking distributions from a 401(k) in addition to receiving a pension, the 401(k) withdrawal counts toward your total income for the phase-out calculation, but it does not get the $10,000 deduction itself.

Interest, dividends, capital gains, rental income, and wages are all taxed as regular income. They count toward the income threshold that phases out your pension exemption, but they do not receive any special deduction.

How to Report Pension Income on Your South Carolina Tax Return

You report pension income on South Carolina Form SC 1040, the state income tax return. Your pension provider will send you a 1099-R form showing how much you received during the year. You enter the gross pension amount on the return and then claim the exemption as a deduction.

The exemption is claimed on the same form where you calculate your total income. You list all income sources, determine whether you are over the phase-out threshold, calculate your remaining exemption, and subtract it from your taxable income. If you use tax software or work with a tax preparer, they will handle this calculation, but understanding the process helps you verify the result.

If you receive multiple pensions — for example, a military pension and a civilian government pension — you combine them for the exemption calculation. You get one $10,000 exemption total, not $10,000 per pension. The exemption applies to your total pension income, not to each pension separately.

When You Might Owe Federal Tax on Your Pension

South Carolina's pension exemption is a state tax benefit only. It does not affect your federal income tax. The federal government taxes all pension income as regular income, with no special exemption for pensions based on age or type. Your federal tax liability depends on your total income, filing status, and the standard deduction for your age.

Some retirees owe no federal tax because their pension income falls below the standard deduction. Others owe federal tax even though they owe no South Carolina tax because of the state exemption. The two tax systems operate independently — a low federal tax bill does not mean you owe no state tax, and vice versa.

Frequently Asked Questions

Do I have to file a South Carolina tax return if my only income is a pension under $10,000?

No. If your only income is a pension under $10,000 and you have no other income, you have no tax liability and do not have to file. However, if you have other income — Social Security, interest, wages — you may be required to file even if your total tax is zero. Check the current filing requirements or contact the South Carolina Department of Revenue.

Does my spouse's pension count toward my income threshold?

Only if you file jointly. Married couples filing jointly combine their income and use the $40,000 threshold. Married couples filing separately each use the $30,000 threshold and each get their own $10,000 exemption. Filing separately usually results in higher total tax, but it may help if one spouse has significantly more income than the other.

If I move out of South Carolina, do I still get the exemption?

No. The exemption applies only to South Carolina residents. If you move to another state, you owe tax according to that state's rules. Some states tax pensions heavily; others exempt them entirely. Your new state of residence determines your pension tax liability once you move.

Can I reduce my income to stay under the phase-out threshold?

You cannot reduce pension income itself, but you can control the timing of other income. For example, you might delay taking a 401(k) withdrawal until the following year, or you might time the sale of an investment to spread capital gains across two tax years. A tax preparer or financial advisor can help you plan withdrawals to minimize tax.

What if I receive a lump-sum pension payment instead of monthly payments?

A lump-sum payment counts as income in the year you receive it. If you receive a large lump sum, your total income for that year may spike above the phase-out threshold, reducing or eliminating your exemption for that year only. The exemption returns to its full amount in future years if your income drops back below the threshold.
