The IRS has reported that tax audits have declined in the last few years. The budget cuts in recent years have left the agency with fewer IRS agents to catch missteps and collect revenue.
As mentioned in Forbes, the number of audits dropped 16% just from the previous year, and that was the sixth year in a row for fewer audits. The chances of audit have always been low, but they have declined even more over the last few years, considerably less than 1%. Sure that makes for a lot of happy taxpayers. No one wants to be audited.
However, infrequent audits can hurt you. Low IRS audit rates are likely to embolden some taxpayers and tax advisers. They may feel that they are in the clear. Statistically speaking, they might be. But someone is going to get audited. And you should prepare as if you will be audited, not assuming that you will not be.
If you are fully prepared for an audit, with documentation, receipts, log books, perhaps even a tax opinion, you probably won’t need them! That is the odd karma about being prepared. Conversely, suppose you figure that you don’t need any of those things, and can produce them if and when you are audited? You guessed it, you probably will get audited. What’s more, you won’t be able to quickly produce all the things you think you can.
Even if you do, the documents will almost certainly be much less persuasive to the IRS than contemporaneous ones would be. And a tax opinion prepared at audit time is rarely entitled to much deference! In short, prepare up front and assume that you’ll be audited. How long are you at risk? Start with the basic rule that the IRS usually has three years after you file to audit you. But this is often extended, sometimes voluntarily. Frequently, the IRS says it needs more time to audit. The IRS asks you to sign a form extending the statute, usually for a year. Most tax advisers tell clients to agree, but get some professional advice. You may be able to limit the time or scope.
An exception to the three year rule is if you omit more than 25% of your income. In that case, the IRS gets double that time, six years. The IRS also gets six years to audit if you omitted more than $5,000 of foreign income (say, interest on an overseas account). For unfiled tax returns, criminal violations or fraud, the IRS has no time limit. In most criminal or civil tax cases, though, the practical limit is six years. And in some cases, even if you file your return, if you miss some tax forms, the IRS can audit forever.
The statute of limitations on taxes is a fundamental rule allowing taxpayers to cut off their exposure. You should never throw out your old tax returns—ever. But after a time—many people say seven years or so—you should be able to throw out records and receipts. Still, some records should be kept forever—like receipts for improvements to property that go into your basis. If you remodel your kitchen and sell your house 20 years later, the receipts for your remodeling job are still relevant. It is comforting to know that your chances of an IRS audit are declining. But someone will be audited, and you might be the one. The best way to avoid much of the pain is to be prepared.
