What does gross up mean? 

In the context of Social Security income, "grossing up" refers to adjusting your income to account for how much of your Social Security benefits will be subject to income tax.  

This is important for retirees because while Social Security benefits are partially tax-exempt, a portion of them may become taxable if your total income exceeds certain thresholds set by the IRS.  

The purpose of grossing up Social Security income is to avoid underestimating your tax liability. By including the taxable portion of your Social Security benefits in your overall income, you can get a clearer idea of what you might owe in taxes, which is essential for budgeting and financial planning in retirement.  

How does grossing up work? 

The "grossing up" step involves adding the taxable portion back into your overall income, providing a more accurate picture of your potential tax liability.  

This is crucial for budgeting and financial planning, especially in retirement.  

In 2024, up to 50% of Social Security income is taxable for single individuals with a total gross income of at least $25,000.  

The same applies to couples filing jointly with a combined gross income of at least $32,000, including Social Security. 

Up to 85% of Social Security income is taxable for individuals with a total gross income of at least $34,000. Couples filing jointly with a combined gross income of at least $44,000, including Social Security, can be taxed at this percentage, too. 

Can everyone gross up their Social Security income? 

Grossing up Social Security income is not necessary for everyone. Whether or not you gross up depends on your total income level.  

The Social Security Administration sets income thresholds that determine if your benefits are taxable. 

If your combined income (which includes your adjusted gross income, nontaxable interest, and half of your Social Security benefits) falls below these thresholds, none of your benefits are subject to tax, and there's no need to gross up.  

However, if your combined income exceeds the threshold, a portion of your benefits may be taxable, making grossing up necessary to accurately estimate your tax liability. 

It is important to note that these thresholds can change annually.  

Based on your specific financial situation, it's advisable to consult the latest IRS guidelines or seek advice from a tax professional to determine if you need to gross up your Social Security income.
