Secrets on Your Tax Forms That Could Ruin You

You Have Children From a Past Relationship — or Affair

“Children don’t need to live with you full time to qualify as dependents, and even non-custodial parents can claim them if it’s part of your separation or divorce agreement,” said Zimmerman. “So, it’s possible to hide the fact that you’re a parent from your current significant other. This could especially cause a problem if those kids weren’t from a past relationship and instead are the result of an infidelity during your current relationship.”

It might be relatively easy to hide children from a significant other when you share custody with the other parent, but tax forms don’t lie. If you’re claiming a child that’s under 19 years old — or under 24 if they’re full-time students — as a dependent, this information will appear on your tax return, said Zimmerman.

If your children are under age 17 and you meet certain requirements, you’re eligible for a tax credit of up to $1,000 per kid. You definitely don’t want to pass up this credit — especially if you want to save money on your taxes — but it will appear on your Form 1040 or Form 1040A.

You Were — or Still Are — Married

“If you’re still married, this information would be on your tax return — even if you’re separated and even if you and your spouse aren’t filing jointly,” said Zimmerman. “If you’re legally divorced but pay or receive alimony, this would also appear on your tax return.”

Even if you’re “single” now, but your divorce wasn’t finalized before the end of the tax year, you still must file as married. You can opt to file separately from your former spouse, but your tax forms will confirm you were married last year.

“This could affect your current relationship if you’d hidden the fact that you were — or still are — married,” said Zimmerman. “Whether you’re cheating on your spouse or just haven’t legally finalized your divorce, anyone you’re dating deserves to know if you’re married. Even if your divorce is final, your significant other would probably be upset to learn that you were married before and didn’t tell them.”

You Lost Your Job

The income you earned last year is the central focus of your tax forms. So, if your spouse catches a glimpse of them, you’re busted.

“Since all your income would appear on your tax returns, if you no longer have a job or are receiving unemployment benefits, this would all be apparent from your return,” said Zimmerman. “You might have hidden your job loss out of embarrassment or shame, but you can’t hide it from the IRS.”

If the earnings on your W-2 are notably less than expected, it will be clear you haven’t been honest. Even if you’ve been secretly holding a part-time job to make ends meet, you’re going to have to explain why you’ve received a W-2 from a company you supposedly don’t work at. And the game you’ve been playing is over.

“If you’ve kept this a secret from your spouse or significant other, it could seriously hurt your relationship,” said Zimmerman. “One of the biggest causes of relationship problems is lack of honest and open communication, especially when it comes to finances.” 

You Have a Secret Stash of Money

If you think your secret stash of cash is exempt from the rules, it’s not.

“You might be able to hide your money from a significant other, but you can’t hide it from the IRS,” said Zimmerman. “Not all of your U.S. bank accounts will be indicated on your return — unless you’ve earned interest on them during the year. But if your significant other notices that your income statements show you made more money than you actually have on hand, they might get suspicious about where the rest of it went.”

Any offshore bank accounts, investments and trusts you have must be reported on your tax forms as well, said Vincenzo Villamena, founder and CEO of CPA firm Online Taxman.

“Foreign bank accounts are noted in (a) few places on the tax return, particularly in Schedule B for interest and dividends — even if you did not receive an income from these accounts — as well as the FBAR and Form 8938,” he said.

You Got a Raise and Kept It a Secret

Whether you got a promotion or salary increase, it’s always exciting to find a little extra padding in your paycheck. The right thing to do is immediately tell your spouse about your raise. But maybe you opted to keep it under wraps.

The thing is, your earnings are the central focus of your income taxes, so your secret is about to be revealed. The amount of money you earned last year will be clearly stated on your W-2 — including bonuses and commissions — and you’ll need to input this on your Form 1040, Form 1040A or Form 1040EZ.

Don’t expect your partner to be happy when they realize you earned extra cash and kept it from them. Even if your family already has plenty of money, this is indicative of a larger problem. Sit your spouse down and spill the beans before they see your tax forms and do the math themselves. Receiving a sincere explanation from you might soften the blow of the news.

You Haven’t Been Honest With the Public

Taxes are private business for most people, but your finances could potentially become an open book if you’re a politician running for office. If you haven’t been playing by the rules, your tax forms could expose many secrets that wouldn’t impress constituents. For example, NPR notes three reasons voters care about politicians’ taxes: potential conflicts of interest, charitable donations and to gauge total net worth.

All sources of income must be listed on Form 1040 — or whichever version you use — blatantly revealing how you earned your money. This could highlight a potential conflict of interest, causing voters to question your priorities.

People typically want to vote for a politician who truly cares about charitable causes. If you’ve embellished your financial support of certain organizations, this could come to light through your tax forms. You can deduct charitable donations to charity by itemizing them on Form 1040, Schedule A. Opting to skip this step is a clear indicator you haven’t been truthful to voters.
