5 Common Business Tax Mistakes That Can Be Costly


As a business owner, it’s important to be aware of the different tax mistakes that you could be making. While some of these mistakes may seem minor, they can actually end up costing you a lot of money in the long run. In this article, we’ll go over some of the most common business tax mistakes so that you can avoid them in the future.

What is IRS?


The Internal Revenue Service (IRS) is the federal agency responsible for enforcing tax laws and collecting taxes. The mission of the IRS is to provide taxpayers top quality service by helping them understand and meet their tax responsibilities and by applying the tax law with integrity and fairness to all. When it comes to making mistakes, the IRS is no different than any other organization. However, because the IRS deals with taxpayers’ money, it is held to a higher standard.

Not Knowing Which Expenses are Tax-Deductible


One of the most common business tax mistakes is not knowing which expenses are tax-deductible. This can be costly because you may be paying taxes on income that you could have deducted.

There are many different types of expenses that can be deducted, but some of the most common include:

– Advertising and marketing expenses

– Travel expenses

– Business entertainment expenses

– Office supplies and equipment

– Employee salaries and benefits

If you’re not sure whether an expense is tax-deductible, you can always speak to business tax accountants or tax advisors. They will be able to help you determine which deductions you can take advantage of.

Not Keeping Good Records


One of the most common and costly tax mistakes businesses make is not keeping good records. Good record keeping is essential to ensuring you are paying the correct amount of tax. It can also help you if you are ever audited by the IRS.

There are several things you should keep track of, including income, expenses, receipts, and mileage. Income includes all money your business brings in, such as sales, investments, and loans. Expenses are all the money your business spends, such as on inventory, rent, salaries, and marketing.

Receipts are important for documenting expenses. Make sure to keep track of all receipts, even if they are for small amounts. Mileage is also important to track if you use your car for business purposes. The IRS has a standard mileage rate that you can deduct on your taxes.

Keeping good records may seem like a lot of work, but it will pay off in the long run. It will save you time and money come tax time, and it will protect you in case of an audit.

Not Filing on Time


One of the most common and costly business tax mistakes is not filing your taxes on time. This can result in late fees, penalties, and interest charges that can quickly add up. If you’re expecting a refund, you may also have to wait longer for it if you file late. To avoid this mistake, be sure to set aside enough time to complete your taxes well in advance of the deadline.

Another common mistake is not keeping accurate records throughout the year. This can make it difficult to track expenses and deductions come tax time. Be sure to keep receipts for all business-related purchases and save them in a safe place. You may also want to consider using accounting software to help streamline the record-keeping process.

If you’re self-employed, one mistake you might make is not setting aside enough money for taxes. Since you’re responsible for paying your own taxes, be sure to estimate how much you’ll owe and put that money aside each month. This will help ensure that you have the funds available when it’s time to pay your taxes.

Finally, another costly mistake is failing to file required tax forms. This can lead to penalties and interest charges, as well as cause problems if you’re audited.

Not Taking Advantage of all the Deductions and Credits You’re Entitled to


When it comes to taxes, there’s no such thing as being too careful. Unfortunately, even the most careful business owners can make mistakes that end up costing them money.

One of the most common mistakes is not taking advantage of all the deductions and credits that you’re entitled to. This can be a costly mistake, because it means you’re paying more in taxes than you need to.

There are a number of deductions and credits that businesses can take advantage of, so it’s important to do your research and make sure you’re taking advantage of everything that’s available to you. If you’re not sure what deductions and credits you’re eligible for, talk to your accountant or tax advisor. They’ll be able to help you maximize your tax savings.

Not Hiring a Professional Tax Preparer or Accountant


One of the most common business tax mistakes that can be costly is not hiring a professional tax preparer or accountant. While you may think you can save money by doing your taxes yourself, it’s important to remember that there are a lot of complexities involved in business taxes. If you make a mistake, it could end up costing you a lot of money in penalties and interest.

A professional tax preparer or accountant will be able to help you maximize your deductions and make sure that you’re taking advantage of all the tax breaks available to your business. They can also help you if you get audited by the IRS. In the end, hiring a professional is worth the investment because it could save you a lot of money and headaches down the road.


There are a number of common business tax mistakes that can be costly. Be sure to avoid these errors by being aware of them and taking steps to ensure accuracy in your filings. With proper care, you can minimize the impact of taxes on your business and avoid costly penalties.
