Know: 10 Tax Loopholes That Could Save You Thousands

1. Losing Out on Deductions

“The biggest mistake people make with taxes is poor bookkeeping,” said Doug Lynam, director of educator retirement services at LongView Asset Management. “As a general rule, if you don’t track an expense, you can’t deduct it — weak data in, weak results out. Be sure to set aside time each week for bookkeeping. Don’t procrastinate! Trying to do all the paper-pushing at tax time is a migraine wrapped inside a nightmare.”

Robert Fishbein, vice president and corporate counsel with Prudential Financial Inc., agreed that keeping track of expenses throughout the year is the best way to make sure you don’t miss any deductions you might qualify for.

“Those who have waited until the last minute to do their taxes often risk losing deductions,” he said. “The time to consider what deductions you have and can report should be a yearlong process. As the year goes on, you should be keeping a list or otherwise collecting the documentation to support such deductions. At year-end, many — but not all — of those deductions will be reported to you, and you can then cross check against your records to confirm the tax reporting is accurate (sometimes the reporting companies make errors!).”

The tax filing deadline is April 15, and this is a deadline you don’t want to miss. The IRS has announced that the federal income tax deadline for individuals is May 17, 2021 for the 2020 tax year. State deadlines have not changed, however, so make sure to confirm your state’s due date before you file.

What happens if you file taxes late? Well, the news isn’t great. “The penalty for missing the filing deadline makes it not just a dumb mistake, but a costly one,” said Nathan Rigney, lead tax research analyst at The Tax Institute at H&R Block. “The penalty for not paying in full is 0.5% of the unpaid balance per month with a maximum of 25%.
