IRS focuses audits on small-business owners

— Worried the Internal Revenue Service might target you for an audit? You probably should be if you own a small business.

A new study by the National Taxpayer Advocate used confidential IRS data to look at tax compliance in different industries and found that people who own construction companies or real estate rental firms might be more likely to fudge their taxes than business owners in other fields.

The IRS uses the information to target taxpayers for audits. The taxpayer advocate, Nina Olsen, runs an independent office within the IRS. She got access to the data as part of an effort to learn more about why some taxpayers are more likely to cheat than others.

The study focused on small-business owners — sole proprietorships, to be specific — because they have more opportunity than the typical individual to cheat on their taxes. Many small businesses deal in cash, while most individuals get paid in wages that are reported to the IRS.

The IRS only audits about 1 percent of tax returns each year, so the agency tries to pick returns that are most likely to yield additional tax money.

The IRS will not say much about how agents choose their targets. But as millions of procrastinators scramble to meet today’s deadline to file their taxes, the agency is running every tax return through a confidential computer program to determine the chances of collecting more money from an audit.

Each tax return is assigned a score. The higher your score, the more likely you are to get audited because, according to the IRS, the more likely you are cheating on your taxes.

The score is called the Discriminant Inventory Function, or DIF. A high DIF score does not guarantee you are a tax cheat, but the IRS says it’s reliable.

“If your return is selected because of a high score under the DIF system, the potential is high that an examination of your return will result in a change to your income tax liability,” says an IRS publication that explains the auditing process.

How do you get high score? The IRS won’t say, but veteran tax preparers and former IRS workers believe they have a pretty good idea.

“If you’re reporting $8,000 of charitable contributions when you’re only making $50,000, that’s a red flag,” said Bob Meighan, vice president of TurboTax, an online tax preparation service. “Likewise if you’re reporting business or employee expenses that are out of the ordinary for your income range, that would attract the interest of the IRS as well.”

The bottom line, according to the experts: People who take unusually large deductions for their income get a high score. Also, business owners who claim unusually large expenses for the size and type of their business get a high score.

“I had a case here where the person made about $40,000 and they claimed $25,000 of employment-related expenses,” said Elizabeth Maresca, a former IRS lawyer who now teaches law at Fordham University. “Most people don’t spend $25,000 to earn $40,000. That’s an unusual number.”

DIF scores can vary across industry, according to the study by the taxpayer advocate. For example, people who owned construction and real estate rental companies were more likely to have high scores. Lawyers, accountants and architects and people who provided other professional services were more likely to have low scores.

Olsen said construction and real estate rental companies probably deduct more expenses that are not independently reported to the IRS. The IRS does not like those kinds of expenses because they are harder to verify without an audit.

“Construction for sole proprietors has been historically a cash business,” Olsen said.

The study, which was included in Olsen’s annual report to Congress in January, used data from 2009 tax returns to plot the DIF scores for sole proprietorships across the country.

Sole proprietorships make up about two-thirds of all U.S. businesses. Sole proprietors account for the biggest share of the tax gap, which is the difference between what taxpayers owe each year under the law and what they actually pay.

The tax gap was $345 billion in 2006, according the latest IRS estimate.
