Now that the new year has officially arrived and things have gone back to normal after the holiday break, it’s time to start turning our attention to the 2013 tax season. The following post will help you to avoid some common mistakes made by small business owners and those classified as self-employed.

Even if you will be handing over your business’ tax filing to an accountant or certified tax preparer, I still recommend that you check out these resources. Business taxation is one of those areas where it pays to at least have a basic understanding of what is going on. This includes any current (and upcoming) legislation affecting small companies and business-related pursuits.

9 Common Business Tax Filing Mistakes to Avoid

There’s no hiding the fact that small businesses owners and the self-employed have been increasingly under the gun to fully comply with tax legislation and reporting requirements. In order to bridge to so called “tax gap” (the amount of tax dollars actually collected versus what was legally owed to the government), the IRS has publicly announced that it is increasing its vigilance on this sector of the tax paying population.

If you want to increase your chances of avoiding an audit and of getting your return as quickly as possible, you need to make an extra effort to prevent some common reporting errors:

1. Not reporting all of your income. One of the biggest tax reporting changes of the past couple of years has been the crackdown on pre-tax income reporting. As I mentioned above, the IRS has been stepping up efforts to reel in all the lost revenue that comes as a result of the non-reporting or under-reporting of taxable income by small businesses and the self-employed in particular. Because of this, make it a point to keep for your records any Form 1099-K’s that you receive. The new form records payments received in 2012 by credit card or through third-party networks such as PayPal. Use them to complete your tax return and to verify income.

2. Not having supporting documentation. When you file a tax return, you will need to have documentation, such as bills and receipts, supporting your deductions. This includes charitable deductions which need to be accompanied by receipts showing the date, the amount given, and name of the organization. You should also have documentation to back up deductions you take for medical expenses, property taxes, mortgage interest and business expenses. Obviously, having the necessary backup documentation on hand is especially important if you will be claiming itemized deductions on your tax return.

3. Not keeping up with tax changes. The U.S. tax code is cumbersome and confusing, and to make matters worse, it just keeps changing. For this reason, you need to make an effort to know which tax legislation changes will affect you and your business. You can do this by consulting with a qualified tax professional and taking a look at some of those free tax recources I mentioned in my previous post.

4. Not taking full advantage of available deductions for small business owners. If you fail to claim a tax deduction that you qualify for, then you are literally leaving money on the table. To get the most accurate list of what you can and cannot claim on your return as a small business owner or a self-employed individual, it’s best to go to the source: The IRS’s web portal for small business owners and the self-employed.

5. But… don’t try to claim too much. There are many well-know red flags that the IRS is looking for when deciding who to audit. One such red flag is seeing larger than normal deductions for a taxpayer’s salary range. So, someone earning $35,000 a year who claims $17,000 in charitable deductions or someone who claims a lot of business expenses for a side business that earns little revenue is more likely to be flagged for an audit. Also, be careful about how you classify your employees. Don’t try to pass a permanent employee off as a contractual worker in order to capitalize on the significant tax difference between the two. If you do get audited, you’ll face some steep fines, penalties, and back-taxes.

6. Filing too quickly. Even if you really want to file your tax return as quickly as possible to get it over with, or you are expecting a significant refund and want to hasten the time it takes to get to you, one of the biggest mistakes you can make is to rush through the process. Those who rush to file their tax returns tend to make more errors, such as forgetting about estimated tax payments made earlier in the year, as well as things as basic as pulling the wrong number from a tax table. They also tend to miss out on tax savings, such as by claiming a standard tax deduction when they would be better off taking the time to make itemized deductions.

On the other hand, if you see that you need more time to file your taxes, then take it. Although the filing deadline is April 15, you can get more time to finish your tax forms if you need it by filing for an extension with Form 4868. Remember, if you owe a tax bill, you must send in that amount (or close to it) by April 15 or you could end up owing more in late-payment penalty charges.

7. Inaccurate information, miscalculations, and omissions. Many times the processing of a tax return is held up due to some small, inadvertent errors and omissions. Using tax software to file your return or the services of a qualified tax preparer can reduce the chances of making such mistakes. But, even these options are not foolproof; you should also make an effort to double check any information that you enter. Here is a list of some common miscalculations and omissions:

  • Claiming the wrong filing status or number of exemptions- especially for nontraditional families, such as unmarried taxpayers living together with children from former relationships or parents living with their adult children.
  • Entering an incorrect Social Security number and spelled names, especially for children claimed as dependents.
  • Mistakes when figuring taxable income (make sure all your W-2s and 1099s are in your possession); withholding; estimated tax payments; Earned Income Tax Credit; Standard Deduction for age 65 or over or blind; the taxable amount of Social Security benefits; and the Child and Dependent Care Credit.
  • Entering incorrect account numbers. If you are due a refund and requested direct deposit, review the routing and account numbers for your financial institution.
  • Forgetting to sign the completed tax form.

8. Not checking for AMT. The Alternative Minimum Tax was created to ensure that high-income taxpayers pay some minimum amount of tax. Instead, it seems to have created an additional headache for many more households than was originally intended. Basically, you are going to need to calculate whether you owe AMT, which disallows some deductions and credits, and pay the higher of AMT or your normal tax liability. The IRS will do this when they get your return, and if you pick the wrong one, they will come after you for the balance, suddenly turning your tax refund into a tax bill!

9. Not seeking the advice and assistance of a tax professional. Being frugal does not mean skimping in areas where expenses are necessary. Seeking the assistance of a qualified tax professional is in many cases a necessary expense if you are running a small business. A tax professional can help you avoid costly tax errors, should know about recent tax law changes, and can assist in you in your long-term tax planning. All of this can pay for the professional fees many times over. For more information on how an accountant can help your small business, see my earlier post.

    Hi Adam,

    Some great points. I especially concur with your final point about people thinking they are saving money by submitting their tax returns themselves when in actual fact it a false-economy because they undoubtedly would receive more of a rebate by hiring the correct professional to minimise their returns.

    Hi again, lol. Still the calm MommaBear here, who used to… guess what? Yup, prepare taxes. For many, many years. You put a lot of great info here, Adam, thank you. I just wanted to mention a couple of things:
    First, your link to “publicly announced” does not seem to work for me.
    Second, the IRS is definitely on the look-out for under-reported income, but something that many people don’t realize is that they are also on the look-out for OVER reported income and/or under-reported expenses in certain (and NOT that uncommon) situations. This sounds backwards to many people, but I have seen it happen frequently, especially when a taxpayer has children and/or low self-employed income, and they qualify for EIC. A larger refund will be seen when reporting more than the actual income possibly combined with omitting some/all of valid expenses.

    As more and more people try to do their own taxes using a program, more people are finding out about this situation, but the problem is, they THINK it’s okay to report too much income – IT IS NOT! They don’t realize that OVER reporting is JUST AS WRONG as UNDER reporting income, and omitting expenses is just a way of over-reporting income.

    I would also like to share something I have discovered over my years of preparing tax returns with those who would like to “save money” by attempting to do their own taxes – especially people that are really NOT familiar with taxes and the tax laws. I have reviewed HUNDREDS of tax returns prepared by other companies as well as by the taxpayers themselves. Most of the taxpayers who prepared their own return using software such as TurboTax (I personally prefer Tax Act) were VERY confident that their taxes were done correctly – before they were reviewed. Hey, the program guarantees accuracy, I heard over and over again. However, like other programs, it can only be as accurate as the information it receives. I have to run, but to sum it up, I found mistakes in OVER 95% of all self-prepared (using popular tax software) returns, and approximately 75% of those mistakes were NOT in the taxpayer’s favor. I amended SO, SO many returns, getting tax payers back thousands upon thousands of dollars they were unaware that they were entitled to. Of course there were a few that owed money too, but many of those were because of either very careless mistakes, or what I believe were intentional “mistakes”. Gotta run. No more MommaBear talk today, lucky you :)
    Take care!

    Hi Sharon,

    Thanks for mentioning the broken link- The article was moved to a different url that also isn’t working.

    And that’s a very high percentage of people making mistakes or not maximizing their tax returns! It could be that by using the software it gives people a false sense of security. They think the program itself will take care of any inaccuracies and maximize their return for them.

    The big downside to all of our technological advances is that people are forgetting how to think.
