5 Common Mistakes to Avoid When Applying For An Ein

Are you in the process of starting a business or managing an existing one? If so, you may have heard of an Employer Identification Number (EIN). An EIN is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to identify businesses for tax purposes. It is necessary for opening a business bank account, hiring employees, and filing tax returns.

However, obtaining an EIN can be a complex process, and there are common mistakes that many people make when applying for one. To help you navigate the process, we’ve compiled a list of five common mistakes to avoid when applying for an EIN.

First, it is important to understand the purpose of an EIN and why it is necessary for your business.

Providing inaccurate information on the application can result in delays or even rejection of your application.

Applying for an EIN too early or too late can also cause problems for your business.

Failing to update or cancel an EIN when needed can lead to confusion and potential legal issues.

Finally, not keeping proper records and documentation can lead to problems when it comes time to file taxes or prove compliance with regulations.

By avoiding these common mistakes, you can ensure a smoother and more successful application when you are going to apply for an EIN.

Not Understanding the Purpose of an EIN

You might be surprised to learn that understanding the true purpose of an EIN is crucial to your business success, and failing to do so could lead to costly errors down the line.

An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to identify businesses for tax purposes. It’s important to note that while the name implies that only employers need an EIN, any business entity, including sole proprietors and LLCs, can apply for one.

One common mistake when applying for an EIN is not understanding exactly why you need one. Some business owners mistakenly believe that an EIN is only necessary if they plan to hire employees, but that’s not the case. If you operate as a sole proprietor, for example, you may be able to use your social security number for tax purposes, but obtaining an EIN can offer additional benefits such as separating your personal and business finances, and making it easier to open a business bank account or apply for a business loan.

By understanding the true purpose of an EIN, you can avoid making costly mistakes that could impact your business down the line.

Providing Inaccurate Information on the Application

Don’t let inaccuracies on your application cause unnecessary delays or headaches in obtaining what you need.

One of the most common mistakes people make when applying for an EIN is providing inaccurate information on their application. This can include misspelling names, getting the wrong address, or even using the wrong social security number.

These mistakes can lead to a delay in processing your application or even a rejection, which means you’ll have to start the application process over again.

To avoid this mistake, be sure to double-check all the information you provide on the application before you submit it. Make sure you have the correct spelling of all names, the right address, and the correct social security number.

If you are unsure about any of the information, take the time to look it up or ask someone who knows. It may seem like a small detail, but it can save you a lot of time and hassle in the long run.

Applying for an EIN Too Early or Too Late

Timing is crucial when obtaining an Employer Identification Number, as submitting the application either before or after the appropriate window can result in significant setbacks and complications.

Applying for an EIN too early can lead to rejection, as the IRS requires that businesses have a specific reason for obtaining an EIN. If you apply too early, your business may not have the necessary documentation or structure in place to justify the need for an EIN. This can result in a delay in obtaining the EIN, which can hinder your business operations.

On the other hand, applying for an EIN too late can also cause problems. If you wait until the last minute to apply for an EIN, you may not receive it in time to meet important deadlines, such as tax filing deadlines. This can result in penalties and fines, which can be costly for your business.

It’s important to plan ahead and apply for an EIN at the appropriate time to avoid any unnecessary setbacks or complications.

Failing to Update or Cancel an EIN When Needed

It’s crucial to keep your business information up-to-date with the IRS, or else you risk facing frustrating and potentially costly consequences.

One common mistake that business owners make is failing to update or cancel an EIN when it’s no longer needed. For example, if your business changes its legal structure, such as from a sole proprietorship to a corporation, you need to apply for a new EIN. If you don’t cancel the old EIN, you may end up filing taxes under the wrong number, which can lead to confusion and even penalties.

Another mistake is not updating your EIN when your business information changes, such as a change in address or name. If the IRS can’t reach you because you’ve moved or changed your phone number, you may miss important notices or deadlines.

Additionally, if you change your business name and don’t update your EIN, you may encounter difficulties when filing taxes or applying for credit. It’s important to keep your EIN information current to avoid any unnecessary hassles or complications down the line.

Not Keeping Proper Records and Documentation

You’ll want to make sure you’re keeping accurate records and documentation for your business to avoid any potential issues with the IRS. This includes keeping track of all your financial transactions, such as income, expenses, and payroll.

You should also keep copies of all invoices, receipts, and bank statements, as well as any contracts or agreements you enter into with vendors or clients. Additionally, it’s important to keep track of any changes to your business structure or ownership, as this can impact your tax obligations.

For example, if you add a partner or change your business entity type, you’ll need to update your records and potentially apply for a new EIN. By keeping thorough and accurate records, you’ll be better prepared to file your taxes and avoid any potential penalties or audits from the IRS.


In conclusion, applying for an EIN can be a daunting task, but avoiding common mistakes can make the process smoother. Make sure you understand the purpose of an EIN and provide accurate information on the application.

Applying for an EIN too early or too late can cause unnecessary delays, so make sure you know when to apply. It’s also important to update or cancel an EIN when needed and keep proper records and documentation.

By avoiding these common mistakes, you can ensure that your EIN application goes smoothly and you can focus on growing your business. Remember, taking the time to properly apply for an EIN can save you time and money in the long run.
