Additional Notes for W-2 Electronic Filing:
- We highly recommend you test your W-2 file in the AccuWage Online tab before submitting your file to the SSA to check for any errors.
- To submit your file to the SSA, the file will need to be renamed before submitting. Your file will be called W2REPORT_2023.FED. Right-click and replace FED with txt. It should not be necessary to zip the file.
- There has been some confusion about the User ID and whether it is required. Even though the BSO has changed the login procedure, the User ID is still required according to the W-2 electronic filing specifications for 2023.

COVID-19 Related Sick Pay
COVID-19 Families First Coronavirus Response Act (FFCRA) US Social Security Employer exemption
This Tax Update contains changes related to FFCRA Sick Pay. If you have employees entitled to this type of pay, you will need to create the following new Income factors for wages required to be paid under the Emergency Paid Sick Leave Act (ESPLA) as enacted under the FFCRA. This Act requires employers with less than 500 employees to provide paid sick leave to employees unable to work or telework after March 31, 2020, and before January 1, 2021 due to reasons outlined below.
Create one or both of the following Income Factors to implement these changes:
In these circumstances, you are entitled to a maximum of $511 per day, or $5,110 total over the entire paid sick leave period.
- Are subject to a Federal, State, or local quarantine or isolation order related to COVID-19;
- Have been advised by a health care provider to self-quarantine due to concerns related to COVID-19;
- Experiencing symptoms of COVID-19 and are seeking medical diagnosis. This falls under the Emergency Paid Sick Leave Act.
In these circumstances, you are entitled to compensation at 2/3 of the greater of the amounts above at a maximum of $200 per day, or $2,000 over the entire two week period.
- Caring for an individual who is subject to a Federal, State, or local quarantine or isolation order related to COVID-19 or an individual who has been advised by a health care provider to self-quarantine due to concerns related to COVID-19;
- Caring for your child whose school or place of care is closed, or child care provider is unavailable, due to COVID-19 related reasons;
- Experiencing any other substantially-similar condition that may arise, as specified by the Secretary of Health and Human Services
This Income must be subject to US SS and any other taxes related to this sick pay. Once you create this Income factor, apply it to eligible employees.
If you previously created an Income for this type of sick pay under a different name, you should change the Income name to COVIDSICK and/or COVIDCARE. In order for this change to be applied to eligible sick pay, it must be called COVIDSICK or COVIDCARE in all caps.
Qualified family leave wages you paid to your employees under the Emergency Family and Medical Leave Act under the FFCRA. This requires employers with less than 500 employees to provide public health emergency leave under the Family and Medical Leave Act of 1993 to an employee who has been employed for at least 30 calendar days. The requirement to provide leave generally applies when an employee is unable to wok or telework due to the need to care for a child under the age of 18 because the school or place of care has been closed, or the childcare provider is unavailable, due to a public health emergency. The first 10 days for which an employee takes leave may be unpaid. During this period, employees may use other forms of paid leave, such as qualified sick leave, accrued sick leave, annual leave, or other paid time off. After an employee takes leave for 10 days, the employer must provide the employee paid leave for up to 10 weeks. The qualified family leave wages can't exceed $200 per day or $10,000 in the aggregate per employee for the year.
Once you create one or both of these Income factors, apply them to eligible employees. This Income must be subjct to US SS and any other taxes related to this sick pay.
If you previously created an Income for these types of sick pay or family leave under a different name, you should change the Income name to COVIDSICK, COVIDCARE, or COVIDFAMILY. In order for this change to be applied to eligible sick pay, it must be called COVIDSICK, COVIDCARE, or COVIDFAMILY in all caps.
Please click here for more detailed instructions on applying these changes.
Instructions for configuring your employees for 2020 W-4s or previous W-4s
Questions?
If you have questions about this information or require our assistance, please contact us here.
Please do the following before installing this update:
- Make a backup of all of your companies.
- Once you install a Tax Update configured for 2020, if you have not previously reconfigured your employees for 2020 W-4s, you will need to go to Payroll/Configure/Employees and reconfigure whichever employees you need to Calculate Payroll for in the future. In other words, you cannot run a payroll for any employee that has not been reconfigured. You do not need to reconfigure employees that you do not need to run payroll for.
- For tips on more efficient payroll configuration, see our Hot Topic: C21 Tips for Efficient Payroll
Configuration information for this Payroll Tax Update
Due to changes to Federal Income Taxes for 2020, you will need to reconfigure your employees before calculating your next payroll, even if you are not using 2020 W-4s. Please keep this in mind before installing this Tax Update as you will need to reconfigure your employees in order for these Tax Tables to be implemented.
After installing this Tax Update, if you do not see the new fields available in Configure/ Employees, go to Payroll/Calculate Payroll, and start a 2020 payroll. Close out of Calculate Payroll and you should see the fields in Configure/Employees.
If you have multiple employees you can reconfigure a little at a time by saving your changes as you go. However, you will not be able to Calculate Payroll for employees that have not bee reconfigured. You can also OK all of your employees and then go back and reconfigure them when you are able. Please note that when you OK your employees, the filing status will default but the status may not be correct. Please double check the status before you run payroll for those employees.
Below you will see references to 2019 Form W-4. This applies to Form W-4 from previous years as well. If an item below only references 2020 Form W-4, you can leave that box blank if you are using a previous year's form.
In Payroll/Configure/Employees, you will see the following Pay Factors for US FIT :
