A partnership EIN is an Employer Identification Number given to a partnership for federal income tax purposes. Essentially, the EIN is the Social Security Number for the business. Most companies will obtain an EIN for federal tax purposes, even if the company isn’t required to file federal taxes. The reason for this is to separate the business from its owners and open a business bank account.
Does a Partnership Need a Separate Tax ID?
Most businesses, including partnerships, must register with the Internal Revenue Service (IRS), along with state and local agencies. For that reason, the business must obtain an EIN. This nine-digit number is issued by the IRS (Form SS-4) and is used to identify your business when submitting tax documents.
Keep in mind that not all business structures are required to obtain an EIN. For example, most sole proprietors utilize their personal Social Security Number as opposed to a business EIN, as the business itself isn’t required to pay federal taxes. Instead, the profits and losses of the sole proprietorship are reported on the sole owner’s personal income tax return. Keep in mind that if you plan on hiring employees for your sole proprietorship, you will be required to obtain an EIN.
Furthermore, those operating a single-member LLC with no employees, meaning that you are the sole owner and have no other owners or employees assisting you in your business operations, then you need not obtain an EIN. However, if you are not the sole owner or if you have employees working for you, then you will need to obtain a separate EIN for your LLC. The reason for this is because any business with employees will have additional tax requirements to abide by; these tax requirements require you to utilize a business EIN rather than a personal Social Security Number. Moreover, if there is more than one owner, such owners cannot use their personal Social Security Numbers. Instead, the IRS requires that you use a business EIN when submitting tax documentation.
However, all partnerships are required to obtain an EIN. While a partnership involves two or more people, they are only required to obtain one EIN. Come tax season, the partners will fill out Form 1065 Schedule K-1, which will assist them in identifying their self-employment income during that taxable year.
EIN Requirements for Different Types of Partnerships
While all partnerships require an EIN, the application process and tax obligations differ based on the partnership type:
- General Partnerships (GPs): Must obtain an EIN and file Form 1065 to report income, though taxes are passed through to individual partners.
- Limited Partnerships (LPs): Similar to GPs, but limited partners may have different tax treatment.
- Limited Liability Partnerships (LLPs): Required to get an EIN and comply with both federal and state-level tax filings.
- Foreign Partnerships: Can apply for an EIN without a Social Security Number (SSN) by submitting Form SS-4 and specifying their foreign status.
- State-Registered Partnerships: Some states require additional filings, such as state-level tax IDs for payroll taxes.
Benefits of Obtaining an EIN
There are many benefits of obtaining an EIN, including the following:
- You can open a business bank account in the name of your business.
- You can apply for credit or loans through the business without having to personally guarantee the loan(s).
- You can obtain business permits and other applicable licenses.
- You can provide any independent contractors that work for your business with a 1099 form, which is required under federal law.
- It can provide additional privacy due to the fact that you are not utilizing your personal Social Security Number.
Tax Implications of Having an EIN
An EIN plays a crucial role in a partnership’s tax obligations:
- Filing Requirements: Partnerships must file Form 1065 annually to report income and deductions, while individual partners report their share of profits on their personal tax returns.
- Employment Taxes: If a partnership has employees, it must withhold and remit payroll taxes using its EIN.
- Excise Taxes: Businesses engaging in activities such as alcohol sales, trucking, or wagering must use their EIN for excise tax filings.
- Avoiding Identity Theft: Using an EIN instead of a Social Security Number helps protect business owners from fraud.
