APA Updated CPP-Remote Exam Questions and Answers by ruth

The Railroad Retirement Tax Act (RRTA) creates a specialized retirement and unemployment insurance system for employees of railroad companies, operating independently of the standard Social Security system. Because railroad workers receive benefits through the RRTA, their wages are explicitly exempt from the Federal Insurance Contributions Act (FICA)—which includes Social Security and Medicare—and the Federal Unemployment Tax Act (FUTA). Instead of FICA, railroad employers and employees pay Tier 1 and Tier 2 taxes under the RRTA, which fund retirement, disability, and survivor benefits. Similarly, the Railroad Unemployment Insurance Act (RUIA) replaces the FUTA system for these specific workers. It is important for payroll professionals to recognize that while exempt from FICA and FUTA, railroad wages remain fully subject to Federal Income Tax Withholding (FITW). This distinct dual-tax structure requires specialized reporting and withholding calculations that differ from standard corporate payroll operations.

Comprehensive and Detailed in-Depth Explanation:

The employee master file includes data relevant to employment, tax, and payroll purposes — like service date , job role , and location . However, dependent names are not required , unless benefits administration is integrated.

Comprehensive and Detailed in Depth Explanation:

A third-party not acting as an agent has specific responsibilities for transferring tax liabilities. They:

Must withhold and deposit the employee’s FICA (A ✅ )

Must notify the employer of FICA paid (D ✅ )

Must provide a detailed statement by January 15th (C ✅ )

However, FIT withholding is optional for non-agent third parties , and if the employer is to assume liability, they will handle FIT themselves. Therefore, withholding FIT using the W-4 is NOT required by a third party that is not an agent.

✅ Correct answer is B

To calculate the monthly federal income tax (FIT) withholding for 2025, we first determine the monthly gross pay: $\$24,000 / 12 = \$2,000.00$. Next, we subtract the pretax medical insurance, which is exempt from FIT: $\$2,000.00 - \$27.00 = \$1,973.00$ (Union dues are post-tax and do not reduce taxable income). Using the 2025 percentage method for a Single filer with Step 2 unchecked, we account for the standard deduction. For a monthly period, the first portion of income (approximately $\$1,250$ in 2025) is taxed at 0% due to the standard deduction. The remaining taxable amount of roughly $\$723$ is taxed at the 10% bracket. After applying the specific IRS 15-T tables and banding, the resulting withholding is $\$72.30$. Accurate manual calculation is a vital skill for payroll professionals to audit system accuracy and handle manual adjustments for employees with lower annual earnings who may still have a tax liability.
