The Truth About Tax IDs: Are They Public Information?

If you are a business owner, taxes are likely one of your greatest sources of aggravation. With so many regulations to follow, it can be challenging to know where to start. One of the confusions that businesses may face is whether their tax ID number is publicly available information. In this article, we will explore the truth about tax IDs and whether they are public or not.

What is a Tax ID and Why is it Important?

A Tax ID, also known as an Employer Identification Number (EIN), is a unique, nine-digit number assigned to businesses by the Internal Revenue Service (IRS) for tax purposes. It is necessary for businesses that have employees or are required to file tax returns. Essentially, a Tax ID is akin to a Social Security number for businesses.

Having a Tax ID is crucial because it enables businesses to file their taxes, open bank accounts, apply for credit, and apply for business licenses and permits. Not having one can lead to legal trouble and fines.

Are Tax IDs Public Information?

The short answer is no. Tax IDs are not public information and are only disclosed to authorized parties, such as the business owners or authorized representatives. The privacy of a business’s tax ID is protected by federal law.

However, there are certain situations where a business’s Tax ID can become public. For instance, any business that files a tax return that is available to the public, such as a non-profit organization, will have their Tax ID included in that return. Additionally, if a business is involved in legal proceedings, their Tax ID may be required to be disclosed.

Why is Protecting Your Tax ID Important?

Protecting your tax ID is vital for several reasons. First, it can help prevent identity theft. Tax IDs are often a crucial component of identity theft schemes, and if a business’s Tax ID falls into the wrong hands, it can be challenging to pinpoint the source of the breach.

Secondly, tax ID theft can lead to significant financial losses and legal repercussions. Thieves can use your Tax ID to file fraudulent tax returns, open credit accounts, and commit various other forms of financial fraud.

Lastly, protecting your Tax ID can safeguard your business’s brand reputation. If a breach occurs, it can lead to negative publicity and harm any relationships your company has with clients, suppliers, and other stakeholders.

How to Protect Your Tax ID?

There are several measures that businesses can take to protect their Tax ID. For starters, they should ensure that all employees and authorized representatives with access to the Tax ID are aware of the importance of maintaining its confidentiality.

Businesses should also avoid sharing their Tax ID number unless it is necessary and authorized. Additionally, they should regularly monitor their credit reports to identify any suspicious activity.

Lastly, using identity theft protection services and implementing strong cybersecurity measures, such as using encrypted connections and firewalls, can help keep your Tax ID safe and secure.


In conclusion, Tax IDs are not public information and are protected by federal law. Businesses that need a Tax ID must obtain one and are responsible for safeguarding it. Protecting your Tax ID is critical, as it can help prevent identity theft and other financial fraud, and safeguard your business’s reputation. By taking the necessary precautions, businesses can help ensure that their Tax ID is kept safe and secure.
