Year-End Tax Updates
November 01, 2023
The end of the year always brings a few tax updates. Here are the changes to be aware of as we head into 2024.
FICA Cost-of-Living Adjustments
As announced by the Social Security Administration, the maximum amount of earnings subject to Social Security tax will increase to $168,600 in 2024 (up from $160,200 in 2023). The Social Security tax withholding rate will remain at 6.2%. With the new wage cap, the maximum withholding for Social Security will be $10,453.20. [Pretty sure, but it’s never a bad idea to check my math. My ability to do math, even with a calculator, is about the same as Justin Timberlake’s in this scene from Friends with Benefits.)
Medicare tax rates also remain the same and are not subject to a maximum (the threshold at which the additional Medicare tax applies is likewise unchanged—this threshold is not tied to inflation).
Thanks to Andrew Schwartz of Armanino for forwarding this year's SSA announcement to me.
How Do This Year’s Adjustments Compare to Prior Years?
This year’s wage base is 5.2% higher than last year’s. This is significant in comparison to past wage base increases. The median increase since 1998 is 3.6% (the average is also 3.6%). Thus, this year’s increase is considerably higher than normal, but it isn’t as high as last year’s, which was a whopping 9% higher than the prior year.
Why Is the Wage Base Increase Different Than the Benefit Increase?
The increase in the Social Security wage base is considerably higher (5.2%, as noted above) than the increase in benefits (3.2%). Why the difference?
Well, the two amounts are calculated differently. Social Security benefits are tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). The Social Security wage base is tied to the National Average Wage Index. In addition, the wage base calculation uses data from the prior year, not the current year. The 2024 wage base increase is tied to 2022 data on wages. The benefits calculation, however, compares the CPI-W for Q3 of the current year to Q3 of the prior year.
Highly Compensated Employee Threshold
The amount of compensation that causes employees to be considered “highly compensated” under Section 414(q) will increase to $155,000 per year (up from $150,000 in 2023, see IRS Notice 2023-75).
For companies who want to exclude highly compensated employees from their Section 423 qualified ESPP, only employees who earn compensation in excess of this threshold can be excluded. Companies can establish a higher exclusion threshold but cannot exclude employees earning at or below this level.
Electronic Filing Threshold
As I mentioned in my October 18 blog, the threshold at which electronic filing is required for various returns employers file with the IRS is dropping from 250 per form to an aggregate of 10 returns. This applies to forms W-2, 1099-NEC, 1099-MISC, 1042-S, 3921, and 3922 (and a whole host of other forms that don’t typically include stock compensation).
To determine if a company is subject to mandatory electronic filing, companies must aggregate the returns filed on all the following forms: W-2, W-2G, 1042-S, the 1094 series, 1095-B, 1095-C, 1097-BTC, 1098, 1098-C, 1098-E, 1098-Q, 1098-T, the 1099 series, 3921, 3922, the 5498 series, and 8027.
It’s a pretty safe bet that any company that offers equity compensation has more than 10 employees, and thus, more than 10 Forms W-2 to file. Where this is the case, if you have to file any of the aforementioned forms for 2023, you will have to file them electronically, even if you are filing less than 10 of any of the forms.
Beware Form W-2 Phishing Scams
The end of the year is a good time for me to remind you to be on the lookout for Form W-2 phishing scams, especially if you work in payroll or HR. Here’s how the scam works: the cybercriminal sends you an email that looks like it is from your CEO or another executive and urgently requests a list of all employees and their Forms W-2. If the scammer manages to procure the list, they will file fraudulent tax returns for the employees to claim any refunds that are due to the employees.
If your company has been victimized by this scam, the IRS has announced special procedures to report this. If you notify the IRS quickly enough, they can take steps to prevent employees from being victimized.
A Few of My Favorite Tax Resources
While we’re on the subject of taxes and heading into year-end tax reporting season, I’d like to mention a few of my favorite resources that are available for NASPP members.
Year-End Tax Reporting Webinar
Our annual webinar on US tax reporting for stock compensation is a handy refresher for this once-a-year task. This year’s webinar is scheduled for December 6.
Tax Reporting Guide
Another one of my favorite resources is our handy Tax Reporting Guide for Stock Plan Transactions, which illustrates, in tabular format, how to report an extensive list of stock plan transactions on Form W-2. It provides an easy-to-use checklist to verify that you are reporting stock plan transactions correctly for federal tax purposes.

Taxation in the Event of Death, Divorce, and Retirement—Videos Available
Death, divorce, and retirement are some of the trickiest tax withholding and reporting scenarios you can encounter for stock compensation. To help you understand the rules, I recorded three videos that cover the tax treatment of equity awards in these situations. Each video is only about ten minutes long and summarizes the company’s US tax reporting and withholding obligations.
