Purpose of Gross Earnings Report

The Form BA-11, Gross Earnings Report, is used to obtain the actual gross earnings of a sample 

group of covered employees. The data collected in the gross earnings is used to estimate future 

tax income and to compute taxes owed for the financial interchange between the Railroad 

Retirement and Social Security/Medicare programs. 

Gross earnings amounts consist of all earnings taxable under the hospital insurance 

portion of the Tier I tax rate. This includes earnings above the taxable limit, sick pay and 

miscellaneous compensation. However, pre-taxable deductions for cafeteria plans (also known as 

flexible benefit plans) should be excluded from creditable compensation.

Reporting Requirements 

Each employer is required by law to report the gross earnings for each employee on the payroll 

whose social security number ends with the digits "30". See Section 7(b)(6) of the Railroad 

Retirement Act and the Railroad Retirement Board's Regulations (20 CFR 209.13). This 

information is an integral part of the data needed to compute taxes owed in the financial 

interchange with the Social Security Administration and the Centers for Medicare & Medicaid 

Services (CMS), and to estimate future tax income.

Due Dates and Frequency of Reports

Gross earnings are to be reported for the same periods as used in determining the employer's 

annual report of creditable service and compensation (Form BA-3). The gross earnings report for 

the preceding calendar year is due the last day of February of the following year. Unless the 

Form BA-11 is filed using the Employer Reporting System (ERSNet), gross earnings reports 

must be accompanied by Form G-440, Report Specifications Sheet. 

All employers are to submit their reports annually with monthly, quarterly, or annual 

breakdowns. Employers with 5,000 or more employees on their payroll during the year are 

required to provide a monthly or quarterly breakdown of the year's earnings. Employers with 

fewer than 5,000 employees may submit only an annual amount, although a monthly or quarterly 

breakdown is preferable. 

Employers with No Employees with SSN Ending in "30" 

If you have no employees with social security numbers ending with the digits “30”, you may file 

a Zero Report Form (No Employee's Ending in a “30”) on ERSNet. Please see Part VIII, Chapter 

3d. Alternatively, you may check the appropriate box on the Form G-440 instead of filing a 

negative Form BA-11.

Common Errors to Avoid 

Below are some helpful hints on how to avoid errors we frequently have found on the Form BA11. 

 Do not limit the amounts in the gross earnings report to the annual Tier I or Tier II 

creditable maximum amounts for the year. 

 Ensure that the gross earnings amount reported for an employee is not less than the Tier I 

amount reported for the employee for the same year. 

 Gross earnings reported on Form BA-11 and creditable compensation reported on Form 

BA-3 must both be reported on the same basis, either "paid" or "earned". 

 Be sure to include in the gross earnings report any new employees hired in a year with a 

"30" social security number.

 Be sure to list all subsidiary BA numbers included in the gross earnings report on Form 

G-440, even if one or more BA numbers have no employees with a "30" social security 

number.
