Chapter 5:    Form CT-1, Employer's Annual Railroad Retirement Tax Return


Who must file


All employers covered under the Railroad Retirement Act are subject to taxation under the Railroad Retirement Tax Act (RRTA) and must file an annual tax return, Form CT-1, Employer's Annual Railroad Retirement Tax Return, with the Internal Revenue Service (IRS). In addition, any non-covered employer who pays compensation subject to RRTA must file Form CT-1.

Where to file All Forms CT-1 are filed at:

Internal Revenue Service Center
Kansas City, MO 64999

 

Due date

Form CT-1 for a calendar year is due at the IRS by the last day of February of the following year.

Obtaining Form CT-1

Form CT-1 is an IRS form, not a RRB form. The IRS releases Form CT-1, and its separate instructions, to employers in December. Form CT-1 is also available on the IRS Internet site at www.irs.gov . If you do not receive a Form CT-1 by December 31, contact the IRS. If you are still unable to obtain Form CT-1, contact QRSC at the number shown on the title page.

Tax rates and compensation bases

The RRB notifies employers in October each year of the tax rates and compensation bases applicable for the following year. This information is also available on the RRB website.

How to make tax deposits Railroad retirement taxes are deposited with an authorized financial institution or a Federal Reserve bank or branch, either electronically or by using Form 8109. Taxes may not be paid to the IRS directly nor to the RRB.

All employers are encouraged to make electronic deposits. Depending on your tax liability in the previous year, you may be required to make your tax deposits electronically. See Form CT-1 for deposit requirements. Electronic deposits are made using RRBLINK system or EFTPS system. Contact RRB Budget and Fiscal section at (312) 751-4668 for more information on electronic deposit systems.

Do not use Form CT-2, Employee Representative's Quarterly Railroad Retirement Tax Return, to make deposits. Only Employee Representatives use Form CT-2.

When to make tax deposits

In general, your total RRTA tax liability in the previous year determines the frequency of your tax deposits. Each November, the IRS will notify employers of their deposit frequency for the coming calendar year. If you do not receive a notification, you must determine your own deposit status. See the deposit rules in the Form CT-1 instructions.

Supplemental tax The Railroad Retirement and Survivor's Improvement Act of 2001 (RRSIA) repealed the Railroad Retirement Supplemental Annuity Tax effective January 1, 2002.  Supplemental annuities provided under the Railroad Retirement Act were not eliminated by the RRSIA, but are now funded through the National Railroad Retirement Investment Trust.

 

Medicare tax

Form CT-1 is also used to report the amount of SSA Medicare tax paid. There is no corresponding employee earnings report that must be filed with the RRB for payment of the Medicare tax.

Penalties and interest

The law provides penalties for failure to file and late filing of a Form CT-1 and failure to pay taxes or late payment or deposit of taxes. Interest is also charged on taxes deposited late at the rate set by law. If you are unavoidably late in filing or paying taxes, send an explanation with Form CT-1. If taxes, which must be withheld, are not withheld and paid, you may be subject to a penalty of 100% of the unpaid taxes.

RRB/IRS coordination The IRS and the RRB have coordination procedures for their respective functions concerning railroad retirement. Form CT-1 information is sent to the RRB for tax reconciliation with that employer's reported creditable compensation for the year.

Representatives from the RRB have no authority to give definitive answers to railroad retirement tax questions. Questions about railroad retirement taxes or completion of Form CT-1 may be directed to a Quality Reporting Service Center reporting specialist at the RRB. However, it may be necessary for them to refer you to an IRS railroad retirement tax specialist for the answers to some questions about railroad retirement taxes.
