Get your taxes done using TurboTax

If TurboTax calculates that the amount of RRTA Tier 1 tax withheld should have been $0, you may need to enter the amount of Railroad Retirement Compensation in Box 14 in addition to the amount of RRTA Tier 1 taxes withheld. That is how TurboTax calculates how much the Tier 1 withholding should be. The amount of Railroad Retirement Compensation in Box 14 should match the Wages reported in Box 1.
