As you near or enter retirement age, it is important to identify the different income streams available to you, as well as how much income you project to receive from each specific source. Among these considerations is Social Security, which can be a significant piece of the retirement income puzzle.
The purpose of this article is to address the common misconceptions about how Social Security is taxed.
Is your benefit taxed? If so, how much is subject to taxation? At what rate?
To fully visualize your retirement income bottom line, it is important to understand the potential tax implications of your Social Security benefits.
Your other income sources may affect the degree to which your Social Security benefit will be subject to taxation. Having substantial income in addition to your monthly Social Security benefit makes it more likely that you’ll pay taxes on a portion of your benefit.
The amount of your benefit subject to taxation is determined by your tax filing status and your combined income (also known as provisional income), defined as:
Combined Income = Adjusted Gross Income + Nontaxable Interest + ½ of your Social Security Benefits
Your combined income is then applied to the following rate schedule (as of the 2023 and 2024 tax years) based on filing status:
| How much of my Social Security benefit is taxable? | |||
| Single Filer | Less than $25,000 | $25,000-$34,000 | More than $34,000 |
| % of benefit taxable | 0% | 50% | 85% |
| Joint Filer | Less than $32,000 | $32,000-$44,000 | More than $44,000 |
The taxability follows a tiered schedule, similar to how ordinary income tax is treated. Here is where it is important to distinguish the difference between the percent of your benefit that is taxable and the rate at which each taxable portion of your benefit is taxed.
Tip: State taxation of Social Security benefits varies from state to state. Be sure to check how your state treats these benefits so you are not hit with an unexpected tax bill.
Let’s look at an example:
John is a single filer, who earned Social Security benefits of $16,000, and has other income of $32,000.
Step 1: Calculate combined income
Combined income = $32,000 + $8,000 (1/2 of his Social Security benefit)
Step 2: Determine John’s combined income in excess of each threshold
Step 3: Calculate John’s total benefit subject to taxation
For a single filer, 50% of the benefit is taxable for combined income that falls between $25,000 and $34,000. For John, this equates to $4,500 ($34,000-$25,000 x 50%)
For a single filer, 85% of the benefit is taxable for combined income that exceeds $34,000. For John, this equates to $5,100 ($40,000 combined income - $34,000 x 85%)
Tip: Taxable Social Security benefits are subject to ordinary income tax rates.
It should be clear by now that overall income (and not just the benefits themselves) drives the taxation of Social Security benefits. This requires a thorough understanding of a retiree’s tax situation and mindfulness of how the increased taxation of benefits might affect your tax bill. Many retirees mismanage their overall income situation and make small decisions that result in substantial impacts on the taxation of their benefits.
Here are some examples of income types that need to be considered when determining your tax situation as it relates to Social Security:
