If you receive Social Security benefits, you might be wondering if that income is taxable. The short answer is yes, it can be, depending on your total income. Understanding these rules is key to managing your finances in retirement. This guide explains how Social Security taxes work and what you can expect for 2025.
Whether you owe federal income tax on your Social Security benefits depends on your “combined income.” This is a specific calculation used by the IRS to determine taxability. Many people are surprised to learn that their benefits are taxed, especially as other sources of retirement income come into play.
The core rules for taxing benefits have not changed in decades, but the financial landscape has. Factors like inflation and cost-of-living adjustments (COLAs) mean that more retirees find themselves crossing the income thresholds each year, making a portion of their benefits taxable for the first time.
To figure out if you’ll owe taxes, you first need to calculate your combined income (also sometimes called provisional income). It’s a straightforward formula:
Your Adjusted Gross Income (AGI) + Nontaxable Interest + One-Half of Your Social Security Benefits = Your Combined Income
Let’s break down those parts:
Once you have your combined income total, you can compare it to the federal income thresholds to see where you stand.
The key thing to understand about these thresholds is that they are not adjusted for inflation. They were set in 1983 and 1993 and have remained the same ever since. This means that as incomes rise over time, more and more people become subject to this tax.
Here are the 2025 thresholds, which are the same as in previous years:
For Individuals:
For Married Couples Filing Jointly:
It’s important to note that “up to 85%” does not mean you pay an 85% tax rate. It means that 85% of your benefit amount is added to your taxable income, which is then taxed at your regular marginal tax rate.
While the tax law itself isn’t changing, the numbers that feed into it are. The most significant factor is the annual Cost-of-Living Adjustment (COLA).
The Social Security Administration announces the COLA for the upcoming year each October. For 2025, early projections from organizations like The Senior Citizens League suggest a COLA in the range of 2.5% to 3.0%. While this increase is meant to help benefits keep pace with inflation, it also raises your total Social Security income.
This increase directly impacts your combined income calculation. A higher benefit amount means the “one-half of your Social Security benefits” part of the formula gets larger. For retirees living near the income thresholds, even a modest COLA can be enough to push them over the line, causing their benefits to become taxable for the first time or moving them from the 50% taxable bracket to the 85% bracket.
Let’s imagine a single retiree, Maria. In 2024, her income was:
Since her combined income is between \(25,000 and \)34,000, up to 50% of her benefits are taxable.
Now, let’s assume a 3% COLA for 2025. Her Social Security benefits will increase to $20,600.
She remains in the same tax bracket. However, if she needed to withdraw more from her IRA, say \(24,000, her new combined income would be \)34,300. This would push her over the $34,000 threshold, and now up to 85% of her benefits would be subject to tax. This illustrates how small changes can have a big impact.
In addition to federal taxes, some states also tax Social Security benefits. The good news is that the majority of states do not. However, as of 2024, the following states may tax Social Security benefits to some degree, though many have their own income exemptions and deductions:
Rules change, so it’s always best to check with your state’s department of revenue for the most current information.
If you expect to owe taxes on your benefits, you have two main options for paying them:
Proactive planning with a financial advisor or tax professional can help you manage withdrawals from other retirement accounts to minimize your tax liability.
Are Social Security disability (SSDI) benefits taxed? Yes, the rules are the same. If your combined income from all sources, including SSDI, exceeds the federal thresholds, a portion of your disability benefits will be taxable.
Are Social Security survivor benefits taxable? Yes, survivor benefits are also subject to the same tax rules based on the survivor’s combined income.
When will the official 2025 COLA be announced? The Social Security Administration typically announces the official COLA for the following year in the second week of October. You will see the change reflected in your January benefit payment.
