Your Ohio Employer Identification Number (EIN), also referred to as a tax ID number, is a company's unique number for reporting taxes to the Internal Revenue Service (IRS). It is essentially a business' Social Security number.
Whether you are referencing an Ohio company or one in another state, the method for finding an EIN will be the same, as it is generated not on the state, but on the federal level. You may be able to find this information with documents you already have.
Look on a recent pay stub. Most pay stubs include an employer's tax ID number listed in a box labeled "EIN."
Refer to an IRS form W-2. The Employer Identification Number can be found in box B above the company's name and address. A W-2 form is an IRS income and tax reporting form usually sent to employees who received payment where income taxes were withheld in the previous tax year.
Refer to an IRS form 1099-Misc. The Employer Identification Number can be found on the second line of the form, in the box just below the payer's name and address. A 1099-Misc form is an IRS income reporting form usually sent to employees or independent contractors of a company who received payment where income taxes were not withheld in the previous tax year.
Search the EDGAR system on the U.S. Securities and Exchange Commission website. If the company is publicly traded on the stock market, you should be able to locate its EIN with the company's name or stock ticker symbol.
Search via the EIN Finder website. EIN Finder is a pay-for-use database of Employer Identification Numbers. Subscriptions to the service start around $100 per month, but a free trial for three free searches is available.
Call the Ohio company's human resources department and ask for the EIN. If you are an employee of the company or a vendor doing business the company, they should give it to you without a problem.
Contact the IRS by calling directly to the Business & Specialty Tax department at (800) 829-4933 Monday through Friday from 7 a.m. to 10 PM Eastern Standard Time to obtain the EIN for your business if you are authorized to receive it. Authorized parties would be company owners (partners or sole proprietors), corporate officers, an acting trustee of a trust or executor of an estate.
