(MM / DD / YYYY)

Part 1: Select ONLY one process.
1. Adjusted railroad retirement tax return. Check this box if you underreported amounts. Also check this box if you overreported amounts
and you would like to use the adjustment process to correct the errors. You must check this box if you are correcting both underreported
and overreported amounts on this form. The amount shown on line 18, if less than 0, may only be applied as a credit to your Form CT-1
for the tax period in which you are filing this form.
2. Claim. Check this box if you overreported amounts only and you would like to use the claim process to ask for a refund or abatement of
the amount shown on line 18. Do not check this box if you are correcting ANY underreported amounts on this form.

Part 2: Complete the certifications.
3. I certify that I have filed or will file Forms W-2, Wage and Tax Statement, or Forms W-2c, Corrected Wage and Tax Statement, as
required.
Note. If you are correcting underreported amounts only, go to Part 3 on page 2 and skip lines 4 and 5. If you are correcting overreported
amounts, for purposes of the certifications on lines 4 and 5, employee Railroad Retirement Tax Act (RRTA) taxes consist of Tier I Employee
tax, Tier I Employee Medicare tax, and Tier II Employee tax. Employer RRTA taxes consist of Tier I Employer tax, Tier I Employer Medicare
tax, and Tier II Employer tax.
4. If you checked line 1 because you are adjusting overreported amounts, check all that apply. You must check at least one box.
I certify that:
a. I repaid or reimbursed each affected employee for the Employee RRTA taxes overcollected in prior years. I have a written statement
from each employee stating that he or she has not claimed (or the claim was rejected) and will not claim a refund or credit for the
overcollection.
b. The adjustment is only for Employer RRTA taxes. I could not find the affected employees or each employee did not give me a
written statement that he or she has not claimed (or the claim was rejected) and will not claim a refund or credit for the
overcollection.
c. The adjustment is for RRTA taxes that I did not withhold from employee compensation.
5. If you checked line 2 because you are claiming a refund or abatement of overreported RRTA taxes, check all that apply.
You must check at least one box.
I certify that:
a. I repaid or reimbursed each affected employee for the Employee RRTA taxes overcollected in prior years. I have a written statement
from each employee stating that he or she has not claimed (or the claim was rejected) and will not claim a refund or credit for the
overcollection.
b. I have a written consent from each affected employee stating that I may file this claim for Employee RRTA taxes overcollected in
prior years. I also have a written statement from each employee stating that he or she has not claimed (or the claim was rejected)
and will not claim a refund or credit for the overcollection.
c. The claim is for Employer RRTA taxes only. I could not find the affected employees, each employee did not give me a written
consent to file a claim for Employee RRTA taxes, or each employee did not give me a written statement that he or she has not
claimed (or the claim was rejected) and will not claim a refund or credit for the overcollection.
d. The claim is for RRTA taxes that I did not withhold from employee compensation.
