Get ahead of your compliance deadlines this month so you can focus on the end-of-year sales push and budget reviews (and enjoy some well-earned time off!). Here are the dates for taxes, payroll, benefits, and HR compliance in December. 

Federal holidays

December 25, 2024

Christmas Day

Whether you’re closing up shop for the day or keeping your doors open, make sure you have a plan in place for the holiday. 

December 31, 2024

New Year’s Eve

Consider how New Year’s Eve (NYE) celebrations will impact your business operations this week, and get organized. 

Tax and payroll compliance deadlines

Payroll tax deposits (for semi-weekly depositors)

Employers who file Forms 940 and 941 have to deposit payroll taxes at different frequencies throughout the year. 

If you report more than $50,000 in payroll taxes during the lookback period of July 1, 2022, to June 30, 2023, you fall into the category of semi-weekly depositor, which means you need to adhere to the payment schedule below:

If payday for your employees is on…Deposit employment taxes by…
WednesdayThe following Wednesday
ThursdayThe following Wednesday
FridayThe following Wednesday
SaturdayThe following Friday
SundayThe following Friday
MondayThe following Friday
TuesdayThe following Friday

However, if you accumulate $100,000 or more of tax liability in a single day, the IRS says you must deposit the amount by the following business day, regardless of whether you normally deposit on a semi-weekly or monthly basis (more on monthly deposits below).

To learn more about federal payroll tax deposits, read Publication 15

Keep in mind that some state and local governments that collect payroll taxes will also expect their own deposits and those deadlines may be different from the federal ones. For more information, contact your state and local tax agencies directly. 

December 2, 2024

Plan for end-of-the-year tax prep

With the end of 2024 only a month away, it’s prime time to start preparing for tax season in 2025. Consider meeting up with your business accountant to make a plan. 

You may need to purchase business equipment or supplies, organize your business expenses and deductions, or gather your documentation for charitable donations. 

Form 730 filing deadline for October wagers

If you accepted wagers during October and meet the below criteria, you have to file Form 730 by December 2 and pay any taxes due (since the last day of the month in November fell on a weekend). The criteria apply if you:

  • conduct a wagering pool or lottery
  • are required to be registered and received wagers for or on behalf of another person but did not report that person’s name and address

Form 2290 filing deadline for vehicles first used in October

Payroll tax deposits for monthly depositors

If your company follows the monthly payroll tax deposit schedule (meaning that you reported less than $50,000 in payroll taxes during the lookback period), then your tax deposit for November payrolls is due on December 16.

HR compliance deadlines

December 1, 2024

Deadline for sending annual notices to plan participants

If you offer retirement benefits to your employees, you’re required by law to distribute certain notices to plan participants every year—no later than December 1. These notices can include: 

  • 401(k) safe harbor annual notice
  • Automatic Contribution Arrangement (ACA) Safe Harbor notice
  • Automatic enrollment notice
  • Participant fee disclosure
  • Qualified default investment alternative (QDIA) notice

If you have to send out multiple notices to participants, you can combine them into one detailed notice. Keep in mind that December 1 is a Sunday this year, so aim to distribute your notices by the end of November if you can. 

December 2, 2024

Review employee handbooks and policies

December is a great time to review your employee handbooks and policies for efficacy, equity, and consistency. Use this month to make any important changes before 2025.

A Summary Annual Report (SAR) explains your company’s retirement plan and other plan details reported in your Form 5500.

Last day to conduct nondiscrimination testing for benefit plans

If you offer 401(k) plans, 125 Premium Only Plans (POPs), and flexible spending accounts (FSAs), you’re required to conduct nondiscrimination testing by December 29. This helps ensure that you’re able to offer benefits on the same terms to all eligible employees at your business. 

Deadline for correcting a failed ADP/ACP test and adopting discretionary amendments

If you need to correct your retirement plan as a result of any Actual Deferral Percentage (ADP) or Actual Contribution Percentage (ACP) testing failures, December 31 is the last day to do so if you want to keep your qualified status. These changes include:

  • Processing corrective distributions for failed ADP/ACP testing (note that a 10% excise tax may apply)
  • Amending plan documents for any discretionary changes implemented during the 2024 plan year

Deadline to change safe harbor status for retirement plans

Any safe harbor status changes that you want to make to your retirement plans must be made by December 31. This includes:

  • Removing a plan’s safe harbor status for the 2025 plan year

Deadline for Required Minimum Distributions due under IRC Section 401(a)(9)

Plan participants who were age 72 and older prior to January 1, 2023 must receive their Required Minimum Distributions (RMDs)—the minimum amount an eligible account holder must withdraw each year—by December 31.
