If you recently filed your 2016 income tax return (rather than filing for an extension) you may now be wondering whether it’s likely that your business could be audited by the IRS based on your filing. Here’s what every business owner should know about the process. Catching the IRS’s Eye Many business audits occur randomly, but a variety of tax-return-related items are likely to raise red flags with the IRS and may lead to an audit. Here are a few examples:

Feeling the urge to purge? April 18, 2017, was the deadline for individuals and C corporations to file their federal income tax returns for 2016 (or to file for an extension). Before you clear your filing cabinets of old financial records, however, it's important to make sure you won't be caught empty-handed if an IRS auditor contacts you.

With the leading edge of the Baby Boomer generation already past the age of 70, the next two decades will see a 90% surge in the number of people in this segment of the population. As the ranks of Baby Boomers residing with their children or remaining independent continue to swell, housing demands are changing. There is a growing need for existing home renovations and new housing that accommodate the needs of this aging population. Where expectant parents baby-proof their homes, many residences now may need to be “senior proofed.” This poses challenges and opportunities for the construction industry.

It’s the goal of many Americans to pass wealth to the next generation. To maximize what goes to your loved ones vs. Uncle Sam, you need to carefully plan your gifts. Giving away assets during your life will help reduce the size of your taxable estate, which is beneficial if you have a large estate that could be subject to estate taxes. For 2016, the lifetime gift and estate tax exemption is $5.45 million (twice that for married couples with proper estate planning strategies in place).

Last year a break valued by many charitably inclined retirees was made permanent: the charitable IRA rollover. If you’re age 70½ or older, you can make direct contributions — up to $100,000 annually — from your IRA to qualified charitable organizations without owing any income tax on the distributions.

A change in the rules governing overtime has been coming for two years, with a sneak preview of proposed modifications last year. But on May 18, the Department of Labor (DOL) came out with its new final rules, which take effect on December 1, 2016. The rules will significantly raise the salary level used to determine whether employees are eligible for overtime and will affect more than 4 million salaried employees, according to the DOL.

It’s not unusual for the IRS to conduct audits of qualified employee benefit plans, including 401(k)s. Plan sponsors are expected to stay in compliance with numerous, frequently changing federal laws and regulations. For example, have you identified all employees eligible for your 401(k) plan and given them the opportunity to make deferral elections? Are employee contributions limited to the amounts allowed under tax law for the calendar year? Does your 401(k) plan pass nondiscrimination tests? Traditional 401(k) plans must be regularly tested to ensure that the contributions don’t discriminate in favor of highly compensated employees.
