Most common mistakes on tax returns according to the IRS<\/strong><\/h2>\n\n\n\n

The IRS gets millions of tax forms every year, and a surprising number of them come with mistakes. But these aren\u2019t always the big, scary errors you might expect\u2014sometimes it’s as simple as forgetting to sign the filing form or mistaking last year\u2019s date for this year\u2019s.<\/p>\n\n\n\n

The vast majority of mistakes relate to simply not being careful when putting in the correct information. A letter or a number here and there, it\u2019s pretty much what it is. Below you\u2019ll find common mistakes<\/a> taxpayers make when filing their tax returns, as highlighted by the IRS.<\/p>\n\n\n

<\/p>\n\n\n\n

These are mistakes that can occur while<\/em> filling out tax forms. However, issues often arise much earlier, during your daily bookkeeping tasks throughout the year. Let\u2019s dive into how this happens.<\/p>\n\n\n\n

1. Misclassification of revenue and expenses <\/strong><\/p>\n\n\n\n

How you classify your business operation matters a lot to tax filing. And it isn\u2019t so much about forgetting to record it, it\u2019s more about not assigning it to the correct account. <\/p>\n\n\n\n

Here are some types of misclassification that I often see in my practice.<\/p>\n\n\n\n

Personal vs. business expenses<\/strong><\/p>\n\n\n\n

Business owners, especially sole proprietors, often blur the lines between personal and business expenses. I know it’s easy to slip up when your business feels like an extension of yourself, but mixing the two can lead to messy finances and potential tax trouble. <\/p>\n\n\n\n

Capital vs. operational expenses<\/strong><\/p>\n\n\n\n

Capital expenses (long-term investments like equipment or property) and operational expenses (day-to-day costs like utilities or rent) must be correctly categorized. Why? Because how and when you deduct them differs, affecting your taxable income.<\/p>\n\n\n\n

Money from loans vs. revenue from sales<\/strong><\/p>\n\n\n\n

When you get a loan, you get money in your account but that\u2019s a liability toward a bank and should be classified accordingly. If you mistakenly record it as sales revenue, you\u2019ll artificially inflate your taxable income, and underplay your actual liabilities.<\/p>\n\n\n\n

2. Misreporting income<\/strong><\/p>\n\n\n\n

Misreporting income is a common, yet serious mistake. Your income greatly affects tax calculations, so any discrepancies are a big red flag for the IRS.<\/p>\n\n\n\n

These errors often happen when not all sources of income make it onto the tax return\u2014whether it\u2019s cash, checks, credit card payments, or any other way you get paid for your products or services.<\/p>\n\n\n\n

Did you know?<\/strong> 

The IRS uses a sophisticated document-matching program\u2014the Automated Underreporter (AUR)<\/strong> system\u2014where forms filed by your customers and information provided by banks, brokerage firms, and other financial institutions are cross-referenced with the income reported on your tax return. <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

<\/p>\n\n\n\n

But it’s not just about forgetting to include all your income sources that can lead to issues. Sometimes, the problem lies in how you categorize that income or in claiming deductions that don\u2019t really apply to your business situation.<\/p>\n\n\n\n

3. Record-keeping mistakes<\/strong><\/p>\n\n\n\n

As you can see, many of these issues stem from poor record-keeping. Whether it\u2019s forgetting to log a transaction or entering it incorrectly, these mistakes can lead to problems when it\u2019s time to file taxes.<\/p>\n\n\n\n

Even if you carefully fill out your tax forms, basing them on incomplete or incorrect information<\/strong> can still land you in trouble with the IRS. It’s not just about doing the paperwork\u2014it’s about making sure the data you\u2019re working with is accurate.<\/p>\n\n\n\n

These records are necessary to support the items of income, deductions, and credits reported on your tax return. Without them, you may have difficulty proving the accuracy of your tax filings if audited.<\/p>\n\n\n\n

How long should you keep the records?<\/strong>

For tax purposes, the IRS advises<\/a> that you generally need to keep records for at least 3 years from the date you file your return.<\/strong> However, certain situations require longer retention.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

4. Overlooked tax deductions and credits <\/strong><\/p>\n\n\n\n

Mistakes don\u2019t always lead to penalties. I see many business owners miss out on valuable tax deductions and credits simply because they aren\u2019t aware of them.<\/p>\n\n\n\n

Deduction or credit?<\/strong>

A deduction reduces your taxable income, meaning you pay taxes on a smaller amount of your income. A credit directly reduces the amount of tax you owe, often dollar-for-dollar. In short, deductions lower your taxable income, while credits lower your tax bill directly.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
