For many retirees, Social Security benefits are the foundation of their retirement income. While these benefits provide valuable financial security, many retirees are surprised to learn that Social Security benefits may be subject to federal income tax. Understanding how these rules work can help you avoid unexpected tax bills and better plan your retirement income.
Are Social Security Benefits Taxable?
The answer is it depends. Whether your Social Security benefits are taxable is based on your combined income, not simply the amount of your Social Security benefits.
Combined income is calculated as:
- Your Adjusted Gross Income (AGI)
- Plus any tax-exempt interest (such as municipal bond interest)
- Plus one-half of your Social Security benefits
The total determines how much, if any, of your Social Security benefits are taxable.
Federal Income Tax Thresholds
For Single taxpayers:
- Combined income below $25,000 – Benefits are generally not taxable.
- $25,000 to $34,000 – Up to 50% of benefits may be taxable.
- Above $34,000 – Up to 85% of benefits may be taxable.
For Married Filing Jointly:
- Combined income below $32,000 – Benefits are generally not taxable.
- $32,000 to $44,000 – Up to 50% of benefits may be taxable.
- Above $44,000 – Up to 85% of benefits may be taxable.
It is important to note that 85% is the maximum portion of your benefits that can be taxed. The taxable portion is simply added to your other taxable income and taxed at your applicable federal income tax rate.
State Taxes on Social Security
The good news is that most states do not tax Social Security benefits.
For our clients in New Jersey and New York, Social Security benefits are fully exempt from State Income Tax, regardless of your income level.
Other Retirement Income Can Increase Taxes
Even if your Social Security benefits would not normally be taxable, additional sources of income can cause more of your benefits to become taxable.
Common examples include:
- Traditional IRA withdrawals
- 401(k) distributions
- Pension income
- Rental income
- Interest and dividends
- Capital gains
- Part-time employment or consulting income
As your retirement income increases, a larger portion of your Social Security benefits may become subject to federal income tax.
Required Minimum Distributions (RMDs)
Once you reach the age at which Required Minimum Distributions (RMDs) begin from traditional IRAs and most retirement plans, those mandatory withdrawals increase your taxable income. This can also cause a greater percentage of your Social Security benefits to become taxable.
Tips to Help Reduce Taxes
While every taxpayer’s situation is unique, some strategies may help minimize taxes during retirement:
- Consider Roth IRA conversions before RMDs begin.
- Carefully plan the timing of IRA withdrawals.
- Spread large withdrawals over several years when possible.
- Coordinate retirement income sources to avoid unnecessary increases in taxable income.
- Consider making Qualified Charitable Distributions (QCDs) from an IRA if you are charitably inclined and eligible.
A well-planned retirement income strategy can often reduce lifetime taxes while preserving more of your retirement savings.
Should You Have Taxes Withheld?
Many retirees receive a surprise tax bill because no federal income taxes are withheld from their Social Security benefits.
If you expect your benefits to be taxable, you may choose to:
- Have federal income tax withheld from your Social Security benefits by filing Form W-4V, or
- Make quarterly estimated tax payments.
Taking one of these steps can help avoid underpayment penalties and unexpected balances due when filing your tax return.
