How to Handle an Unexpected Tax Bill in 4 Steps

If you’re like most Americans, the process of filing taxes – while painful – typically results in a refund from the IRS.

So far this year, 84 percent of filers have received a refund. The average refund amount this year is just over $3,000.

The percentage of filers receiving refunds from the IRS typically declines as April 15 approaches, since people who owe taxes tend to file returns later. The majority of those who owe money expect a tax bill. Each year, however, millions of Americans file their taxes expecting a refund; instead, they’re socked with an unexpected tax bill that can be difficult to pay.

It’s worth noting that owing taxes is not inherently a bad thing. People who routinely receive large refunds are overpaying taxes throughout the year and are essentially giving the federal government an interest-free loan. “Tax refunds aren’t just free money, after all,” says Melanie Lauridsen of the American Institute for Certified Public Accountants.

If you’ve done proper tax planning throughout the year, there shouldn’t be any surprises at tax time. However, common reasons for an unforeseen tax bill include improperly filling out W-4s and not withholding enough; a life event, such as an inheritance or a divorce resulting in an unexpected windfall; or incorrect payments by quarterly filers.

Whatever the cause, receiving a tax bill you hadn’t planned for can be an unsettling event, especially if the amount you owe is large and you don’t have the cash available to pay it out of pocket.

Here’s what to do if it happens to you.

Don’t panic. First, make sure you actually owe the amount you believe you owe. Examine your returns from last year to see what changes are resulting in a higher bill and alert your tax preparer so you can work together on fixing the problem. Often a big swing in tax obligations could reflect a mistake made in filling out forms. If you don’t think you owe a large amount and you did your taxes yourself, if may be worth having a professional check your returns to see if you missed anything (or getting a second preparer to check the work of the first one).

The simplest and easiest way to deal with the burden, of course, is to pay it immediately. If that’s not possible, keep reading.

File your taxes anyway and pay whatever amount you can. Too often, taxpayers who owe money decide not to file until they’re able to cover the costs. That’s the worst possible move, since failing to file can result in fees and accrued interest that can push your obligation even higher. In addition, the IRS can put liens on your home or garnish wages if you’ve made no effort to pay the taxes you owe.
