Final answer:
The three IRS computer programs used to check tax returns are Automated Underreporter (AUR), Electronic Fraud Detection System (EFDS), and Information Returns Processing (IRP).
Step-by-step explanation:
Three IRS computer programs that are used to check tax returns are:
- Automated Underreporter (AUR): This program identifies discrepancies between the income reported on a taxpayer's return and the information provided by employers, banks, and other payers. It flags potential errors or omissions that may require further review.
- Electronic Fraud Detection System (EFDS): This program uses algorithms to analyze tax returns and detect patterns that may indicate fraudulent activity. It helps identify fraudulent tax returns and prevent improper refund claims.
- Information Returns Processing (IRP): This program processes and matches the information returns (e.g., W-2s, 1099s) submitted by employers and other payers to the income reported on taxpayers' returns. It helps ensure accuracy in reporting and compliance with tax laws.
