5 Common Tax Mistakes Small Business Owners Make (and How to Avoid Them)

Running a small business comes with many responsibilities, and taxes can be one of the most overwhelming aspects. Unfortunately, small business owners often make mistakes that can lead to penalties, missed deductions, or even an IRS audit. Here are five common tax mistakes and how you can avoid them.

1. Mixing Personal and Business Finances

One of the biggest mistakes business owners make is not separating their personal and business finances. Using a personal bank account for business expenses can make it difficult to track deductions and increases the risk of errors during tax filing.

How to Avoid It: Open a dedicated business bank account and credit card. This will help keep your records clean and make tax time much smoother.

2. Not Keeping Proper Records

Poor record-keeping is a leading cause of tax errors. Without accurate records, you could miss valuable deductions or have trouble verifying expenses if audited.

How to Avoid It: Implement an organized bookkeeping system. Use accounting software like QuickBooks or Xero, and keep digital copies of receipts and invoices.

3. Failing to Make Estimated Tax Payments

Many small business owners, especially new ones, are unaware that they must make quarterly estimated tax payments. If you don’t pay enough throughout the year, you could face penalties when you file your return.

How to Avoid It: Determine your estimated tax liability and make payments to the IRS quarterly (April, June, September, and January). A tax professional can help you calculate the correct amount.

4. Overlooking Deductions and Credits

Business owners often miss out on deductions and credits that could reduce their tax burden. Commonly overlooked deductions include home office expenses, mileage, and business-related meals.

How to Avoid It: Stay informed about tax deductions available to small businesses. Work with a tax professional to ensure you’re claiming all eligible expenses.

5. Filing Late or Incorrectly

Missing the tax filing deadline or submitting incorrect information can lead to penalties and interest charges.

How to Avoid It: Mark important tax deadlines on your calendar and file early whenever possible. Double-check all details before submitting, and consider working with a tax professional to review your return.
