Understanding the Differential Income Factor Method [DIF Method] for Tax Audits

Definition & Meaning

The Differential Income Factor Method, commonly known as the DIF Method, is a technique employed by the Internal Revenue Service (IRS) to determine which tax returns should be audited. Under this method, each tax return submitted to the IRS receives a score based on the reported income and the types and amounts of deductions claimed. This score, referred to as the DIF score, helps the IRS identify returns that may require further scrutiny. If a tax return's DIF score surpasses a specific threshold, it is added to the pool of returns selected for auditing. Generally, a higher ratio of expenses to income results in a higher DIF score.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A small business reports $50,000 in income and claims $40,000 in deductions. This high ratio of expenses to income may result in a higher DIF score, increasing the likelihood of an audit.

Example 2: An individual taxpayer reports $70,000 in income and claims $10,000 in deductions. This lower ratio may yield a lower DIF score, making it less likely for the return to be audited. (hypothetical example)
