Impeding Internal Revenue Service (IRS) is a form of fraud or tax evasion involving the use of false documents, false statements or other means to interfere with the Internal Revenue Service's ability to collect taxes. The most common forms of Impeding Internal Revenue Service include: 1. Filing False Tax Returns: This is the act of filing a false tax return with the IRS. This includes underreporting income, overstating deductions, or claiming false credits. 2. Tax Evasion: This is the deliberate attempt to evade paying taxes by concealing income or assets. This includes hiding income offshore, using false deductions or credits, or making false statements. 3. Tax Fraud: This is a criminal act of intentionally misrepresenting facts or withholding information to mislead the IRS in order to gain a tax advantage. This includes filing false returns, filing multiple returns, and submitting false documents. 4. Money Laundering: This is the process of disguising illegally obtained funds or assets in order to make them appear legitimate. Money laundering is often used to avoid taxes or to hide the true source of income. 5. Identity Theft: This is the act of using someone else's identity to file a false tax return or to gain access to another person's bank account or credit card information. This type of fraud has become increasingly common in recent years.
