But if you think you have to be caught stowing away cash in an offshore bank account to trigger an audit, you better think again. One tiny error on your tax returns can have the IRS knocking on your door. In 2007, the IRS audited approximately 1.4 million returns, a 7% increase from 2006 and the highest number on record since 1998.
The best way to avoid an audit (and to deal with one) is to keep detailed records, such as receipts and bank statements that substantiate every claim, loss and deduction in your returns.
Here are five common red flags that catch the IRS's eye and how to avoid them.
People who claim the earned income credit — a tax break for lower-income individuals - are also likely to face an audit, says Mark Luscombe, a principal analyst at CCH Tax and Accounting. That's because income requirements for this credit are very strict. You qualify if you have one child and your adjusted gross income was less than $33,241 in 2007 ($35,241 if you are married, filing jointly) or if you have more than one child and earned less than $37,783 ($39,783 if married, filing jointly). If you don't have children, your adjusted gross income needs to have been less than $12,590 ($14,590 if married, filing jointly). Ultimately, this tax break can provide much needed relief to families that are in financial distress. The maximum credit is $4,716 for filers who qualify and have two or more children.
On the other end of the spectrum, the IRS is also auditing more people with high incomes. During 2007, the IRS audited some 293,000 returns of individual with incomes of $100,000 or more and around 113,000 returns with incomes higher than $200,000. That's a 13.7% and 29.2% increase, respectively, from 2006.
If you get audited, you'll have to prove that your business — whether it's full-time or a sideline venture — is legitimate and that its goal is to make money. You'll need detailed records, including all documentation related to income and expenses, a business plan, business bank accounts, and a business license, which you'd receive from your local municipality, says Dennis.
"The question that the IRS will try to answer is whether you're engaged in a small business or a personal hobby," says Luscombe. Some categories, especially if they're leisurely, like painting or writing, can raise many questions, he says. On the other hand, the chances of you getting audited because you lost money from, say, your sewer excavation business are low, he says. Generally, the activity is presumed to be a business, and not a hobby, if profits resulted in three of the last five years.
You'll also need a letter for any used clothing or household items you donate to an organization. The letter must include a good description of the product (a photo of the item also helps), the date that you donated it and the method you used to value it, says Saks. One way is to visit a thrift shop to find out how much the items can be resold for, she says. Keep in mind that noncash gifts need to be in good condition or better in order to receive a deduction. If they're worth more than $500, you'll need to fill out form 8283.
In order to qualify, you'll need to prove that your home office is your principal place of business, that it's strictly for meeting with customers or clients, and used exclusively for business, says McGetrick. You won't be eligible for a deduction if you use the office for business during the day and as a family room at night or if your employer is offering you work space at the company office.
The table below shows the average deductions made by different income groups in 2005 (the most recent available) based on their adjusted gross income, which includes your gross taxable income, such as wages, interest and dividend income, and capital gains, adjusted by deductions. Use this as a guide to assess where your deductions stand.
