2018 NerdWallet Tax Study
Most Americans in the Dark on Key Deductions and Rules
By Erin El Issa
Are you getting all of your deductions this tax season? According to a new NerdWallet survey, many Americans think some legitimate tax-reduction strategies are illegal, which could be leading them to miss out on money-saving deductions.
In online surveys of more than 2,000 U.S. adults each, commissioned by NerdWallet and conducted by Harris Poll, we polled Americans on legal and illegal tax-saving strategies, tax bracket knowledge, concerns about filing taxes incorrectly and understanding the new tax bill. Here’s what we learned:
- Many Americans think several legal tax-reduction strategies are illegal, including making extra mortgage payments (65%), contributing to or opening an IRA after the end of the year (75%) and delaying income (78%). Yet 1 in 10 Americans think it’s OK to not include tips/income received “under the table” when filing their income taxes; 6% of Americans believed doing so was legal.
- About 9 in 10 Americans (89%) would be worried if they discovered they had filed their income taxes incorrectly. The biggest concern is getting audited (28%), followed by having to pay more after filing (21%).
- Almost half of Americans (48%) don’t know what income tax bracket they’re in for 2017, compared to 40% in 2016.
- About 1 in 4 Americans (26%) don’t know that a new tax bill was signed into law in 2017, and about half (51%) don’t know that income tax brackets are changing under the new rules.
Americans are missing out on legal tax-saving strategies
According to our tax-filing survey, many Americans are confused about which tax-saving strategies are legal. We asked them about the legality of the following activities:
Most Americans know that activities such as not including “under-the-table” tips and income (90%), overstating donations (96%) and not reporting gambling income (97%) are illegal. However, many Americans think some legal tax-saving activities are illegal, too. Roughly 9 in 10 think taking a home office deduction when your office is used for activities other than work is illegal, and three-quarters believe contributing to an IRA after year-end but before the tax deadline (75%) is against the law.
Only 16% of Americans who have filed income taxes have taken advantage of at least one of the five legal tax-saving strategies listed above.
Some Americans have used illegal tax strategies to cut down on their tax bill. A larger portion of millennials (ages 18-34; 20%) have participated in at least one of the illegal activities shown in the chart below than Generation Xers (ages 35-54; 15%) and baby boomers (aged 55+; 10%).
Of course, most Americans err on the side of safety, likely because they’re concerned about what could happen if they file their returns incorrectly.
Americans are concerned about filing their taxes incorrectly
More than 1 in 10 Americans (11%) say that they wouldn’t be worried if they discovered they had filed their income taxes incorrectly; but it’s a logical concern to have, as the consequences can be serious. For the rest of Americans (89%), the biggest worries are getting audited (28%) and having to pay more after filing (21%).
Concerns are different for those with a higher annual household income versus those with a lower annual household income. Americans with household incomes of $100,000 or more (32%) are more likely to be most concerned about getting audited if they file incorrectly than those with household income of less than $50,000 (24%). Those whose household income is less than $50,000 (14%) are more likely to be most concerned about not getting the full refund they deserve than those whose household income is $75,000 or more (9%).
Baby boomers (15%) are more likely than Gen Xers and millennials (8% each) to report that they wouldn’t be worried about anything if they discovered that they had filed their income taxes incorrectly. But they’re more likely to be most worried that they’ll have to pay more after filing than other generations (26%, compared to 21% of Gen Xers and 14% of millennials).
About a quarter of Americans think they’ll be audited
Almost 1 in 4 Americans (24%) think it’s likely that they’ll ever be audited by the IRS. But on an annual basis, the chance of audit is actually very low. For example, in 2016, 0.70% of individual tax returns were audited, according to The Wall Street Journal. Higher income earners are more likely to be audited than lower income earners — 1.7% of those making $200,000 or more were audited in 2016, compared to 0.65% of those making less than $200,000. Even for very high earners, the chances aren’t that high — 5.83% of those making $1 million or more were audited in 2016.
A smaller proportion of millennials think they’ll be audited (20%), compared to Gen Xers (27%) and baby boomers (25%). And almost 2 in 5 millennials (39%) think it’s not at all likely, compared to 26% each of Gen Xers and baby boomers.
About half of Americans don’t know what tax bracket they’re in
Last year, we surveyed Americans about what federal income tax bracket they were in for the 2016 tax year, and 2 in 5 reported that they didn’t know. For the 2017 tax year, this has increased, with almost half of Americans (48%) unsure of their tax bracket.
This year about 1 in 14 Americans (7%) don’t know what a tax bracket is, but this is a slight improvement on last year (10%). Millennials are most likely to not know what a tax bracket is (16%, compared to 4% of Gen Xers and 3% of baby boomers).
The U.S. has a progressive tax plan, so the higher your income, the higher your tax rates. But your income isn’t taxed all at one rate; instead each chunk of income is taxed at a corresponding rate. For example, if you’re a single filer making $30,000, the first $9,325 is taxed at 10% and the rest is taxed at 15%.
Americans are no more tax savvy this year than they were last year
Slightly more Americans can correctly describe a W-4 this year compared to last year, 45% versus 40%. A W-4 is a form a person fills out to tell an employer how much to withhold from their pay for taxes. Millennials were most likely to incorrectly describe a W-4 this year (63%, compared to 54% of Gen Xers and 51% of baby boomers).
However, we asked Americans to indicate whether they thought several statements about the tax year 2017 were true or false, or if they were not at all sure. The percentage of those who answered incorrectly is largely unchanged from last year:
Deducting 529 plan contributions: Contributions to a 529 college savings plan aren’t tax deductible on your federal taxes, but many states offer such a deduction. The federal benefit from 529 plans is that earnings are tax-free if used on qualified education expenses. Parents (91%) are just as likely as nonparents (92%) to answer this incorrectly.
Deducting volunteer mileage: Mileage from driving back and forth for volunteer work can be tax-deductible. For 2017, the mileage deduction is 14 cents per mile or your actual variable costs of operating your vehicle for volunteer purposes, like gasoline and oil. Your fixed vehicle costs — like depreciation, payments and insurance — aren’t deductible.
Extension on tax payments: While you can file an extension for your tax return, you can’t delay your tax payment. This means for tax year 2017, your tax owed is due on April 17, 2018, even if you get an extension on filing your tax return.
Adjusting federal tax withholdings: The number of allowances you claim affects how much tax you pay with each paycheck, and that affects whether you get a refund or owe a bill at tax time. Taxpayers can change their withholding elections at any time.“If you’ve had any major changes in your life since you last filled out a W-4, such as getting married or divorced, having a baby, or buying a house, consider filling out a new form to adjust your withholding,” says Andrea Coombes, an investing and retirement specialist at NerdWallet.
“Also, given the new tax law, you might want to check your withholding in 2018, just to be sure the new withholding calculations suit your situation,” Coombes says. Check out our tips for how to fill out a W-4.
Tax law is changing, but many Americans aren’t sure how
A tax reform bill was signed into law in 2017, but more than a quarter of Americans (26%) don’t know that. Millennials are least likely to know this, 41% compared to 27% of Gen Xers and 14% of baby boomers.
Americans have varying opinions on whether the new tax law will be good or bad for the U.S. economy over the short term and long term:
While most Americans know something is changing under the new tax law (74%), not everyone knows exactly what that something is. Only about half of Americans (49%) know that income tax brackets are changing under the new tax law, and only 34% of millennials know this. Across the board, millennials are least likely to be sure of what tax rules are changing, followed by Gen Xers and then baby boomers — respectively, they answered “not at all sure” at 38%, 24% and 17%.
Here’s how Americans responded when we asked what was changing under the new tax law:
Half of Americans (50%) don’t understand how their income tax bracket will change under the new tax law, and there are clear generational differences in the percentage of Americans who know tax brackets, in general, are changing versus the percentage who know how their tax bracket is changing:
Here’s what you should do
There are several things we recommend doing to better understand your taxes and avoid paying more than you have to this tax season:
Estimate your tax burden for 2017: Don’t be caught off guard when you sit down to do your taxes. Plug your income, deductions and credits into NerdWallet’s federal tax calculator to get an idea of what you’ll owe in April.
Familiarize yourself with the new tax law and how it will impact you: Understanding the new tax law and its impact on you will help you make financial moves to save on taxes in the future. The tax law itself is over 1,000 pages, but NerdWallet has broken it down to make it easier for you. Find out if your taxes will go up or down under the new tax rules.
Consider hiring a tax professional or use reputable online tax software: “To make sure you don’t file your taxes incorrectly and unintentionally attract the IRS’ attention, be sure to use a highly rated tax preparer, whether you hire a pro, like a certified public accountant or enrolled agent, or use online tax software,” Coombes says. Here are 7 questions to ask before you hire a tax professional and an overview of the best tax software for 2017.
Understand your tax bracket and how it’s changing: There will continue to be seven tax brackets in 2018, but they’re changing a bit. For more information about tax brackets and rates for 2017, and to help you determine your tax bracket under the new tax law, check out NerdWallet’s guide to 2017-2018 federal income tax brackets.
Also note that there’s a difference between tax avoidance and tax evasion. Evading taxes is a crime; avoiding them within the constraints of the law is savvy. The following activities are perfectly legal, as long as you follow the IRS rules:
Making an extra mortgage payment or paying property taxes early to take a bigger deduction in the current tax year: “For people who fall near the break-even point for itemizing — that is, they have deductible expenses but those expenses add up to about the same amount as the standard deduction — bunching deductible expenses into one year might be worthwhile,” says Coombes. That way, itemizing in one year makes sense, followed by taking the standard deduction the next year.
For example, “it’s legal to pay property taxes early and deduct that expense off your taxes that year, rather than the following year, as long those property taxes have been assessed,” she says. However, you can’t estimate your property taxes for the following year and then prepay them in the hopes of getting a tax deduction.
Contributing to or opening a traditional IRA after Dec. 31 but before the tax deadline to reduce taxable income: The deadline for opening and contributing to a traditional IRA is the tax deadline. For the tax year 2017, this is April 17, 2018. According to our survey, only around a third of Americans (34%) know that this is the deadline for making a tax-deductible contribution to a traditional IRA.
Delaying income to the next tax year: It’s legal to ask your employer to pay out a bonus in January instead of December, or delay billing clients until the new year. But keep in mind, you will owe taxes on this delayed income next year.
Combining a vacation with a business trip and then deducting the unreimbursed business expenses: You can deduct unreimbursed business expenses, but not personal vacation expenses.
Taking the home office deduction when your home office is used for functions other than working: The rules for the home-office deduction are complex. One key provision is that it’s possible to deduct the expenses related to the area of your home used for work. “You don’t have to designate an entire room as your home office, but it’s vital that the area you claim — the actual square footage — is devoted to work and nothing else,” Coombes says. For example, you can claim part of your spare room as a home office, as long as that part of the room is exclusively used for work.
