Advantages of an EIN Number for the Business

Advantages of an EIN Number for the Business

An EIN is a valuable element for a business. Every professional before starting a business must receive this number. Here are some merits that EINs offer to businesses.

Differentiate Between Business and Personal Finance

EIN is helpful to keep your finances different from business capital. This is majorly useful for independent contractors and freelancers. Business professionals can perform various financial transactions using unique identifiers. Through EIN, it is possible to open a separate business bank account, take a separate business loan, and tax filing. Thus, there is a systematic finance management of the business.

Prevent the Chances of Identity Theft

EIN is a fantastic substitute for social security numbers. Businesses can give EINs instead of sharing social security numbers. Businesses are not required to give the social security number of the actual SSN to the vendor or the customer. This minimizes the likelihood of theft of personal information. Moreover, sharing an EIN looks more professional, rather than sharing a personal social security number.

Give More Loan Opportunities

Acquiring bank loans without an EIN is possible. However, some banks need an EIN to approve business loans. To get a bank loan, it is compulsory to have a business checking account that needs an EIN. Businesses avail high loan opportunities with EIN.

Hire Employees and Payroll Purposes

EIN is mandatory when you have employees in your organization or hire an employee in the future. Even it will be worth applying and getting an EIN if your company has no employees. This is because it helps in running the payroll process easily. If you have no employees, then also acquiring an EIN will not be the wrong thing.

Credit Building

EIN is an essential element in forming a company’s credit history. Developing credit for the business is helpful as financial needs get explored. In such cases, you can use business credit instead of your own.

Taxpayer Identification Number (TIN) vs Employee Identification Number

A Taxpayer Identification Number broadly refers to different types of identification numbers. It would be right to say EIN is a part of TIN, thus the TIN is generic. It covers the following numbers –

  • Social Security Number (SSN)
  • Employer Identification Number (EIN)
  • Taxpayer Identification Number for Pending US adoptions (AITN)
  • Preparer Taxpayer Identification Number (PTIN)
  • Individual Taxpayer Identification Number (ITIN)

TIN is a social security number for sole proprietorships whereas EIN is for corporations, trusts, partnerships, and estates.

Last Word

Hope you have a clear picture of what is an EIN, through this blog. Remember, EIN is a crucial part of the business for tax filing, hiring employees, and other purposes. Thus, business professionals must get an EIN early to run their profession smoothly.
