As we turn the calendar to a new year, there are several calendar year end reminders to bump to the top of your to-do list. 

Payroll Reminders and Updates

W2’s must be filed with the Social Security Administration and mailed to your employees no later than January 31, 2024.

It is important to ensure your W2 file is completely reconciled to all four quarter 2023 941s.

If this is the first time you will be filing W-2s on behalf of your organization, be sure you have set up a Business Service Online (BSO) account. This can take up to two weeks to complete the registration process.  All organizations with 10 or more information returns must file with the Social Security Administration electronically. 

Employees who have claimed “exempt” on their W-4 or A-4 must refile their tax certification form no later than February 15, 2024.  If this is not refiled, the employer is required to change the employees withholding to single, zero deductions for federal withholdings and the default 2% withholding rate for state withholdings until the employee provides the employer with an updated A-4.

2024 Wage Updates

Arizona minimum wage has increased to $14.35 per hour for all non-exempt employees (City of Flagstaff increased to $17.40 per hour) effective January 1, 2024.  It is important to ensure all hourly, non-exempt wages earned as of this date is paid at least this rate.  If your work week/pay period crosses over January 1, it might be advantageous to have the minimum wage increase applied to the entire pay period to avoid any payroll calculation errors.

The Social Security wage base limit will increase to $168,600 for calendar year 2024.  This means any wages over $168,600 will not pay social security payroll tax.  A reminder of the additional employer withholding of 0.9% additional Medicare tax on an individual’s wages paid in excess of $200,000 in a calendar year, without regard to filing status.

The 2024 contribution limits for 403(b), 457(b) and 401(k) plans increased to $23,000 with a $7,500 catch-up contribution for employees who are 50 and older.

Accounts Payable/1099 Reminders & Updates

Effective calendar year 2024 for 1099s issued for 2023, organizations that file 10 or more information returns must submit the 1099s electronically to the IRS.

1099-NEC and 1099-MISC must be mailed/distributed on or before January 31, 2024.  The 1099-NEC must be filed with the IRS by January 31, 2024 as well.  The 1099-Misc must be filed with the IRS by February 28, 2024 if filed on paper or by April 1, 2024 if filed electronically.
