How to enter your TIN and federal tax classification – Remofirst

When completing your U.S. tax form in RemoFirst, you will need to provide a Taxpayer Identification Number (TIN) and select your federal tax classification.

This guide explains how to obtain a TIN and choose the appropriate classification.

What's a TIN?

A Taxpayer Identification Number (TIN) is a unique identifier used by tax authorities to track tax obligations and payments. Depending on your status (individual vs. business), this number can take several forms.

For U.S. contractors working with U.S. entities, the TIN is required for reporting income to the IRS via forms like the W-9 and 1099-NEC.

For Individuals: This is generally your Social Security Number (SSN).
For Resident Aliens: If you are not eligible for an SSN, you must use an Individual Taxpayer Identification Number (ITIN).
For Businesses/Entities: This is typically an Employer Identification Number (EIN). How to obtain a TIN

If you do not have a TIN, apply for the identification number that applies to you.

Social Security number (SSN)

Complete Form SS-5, Application for a Social Security Card.

You can obtain the form:

From your local Social Security Administration (SSA) office
From the SSA website
By calling 800-772-1213

Individual Taxpayer Identification Number (ITIN)

Complete Form W-7, Application for IRS Individual Taxpayer Identification Number.

Employer Identification Number (EIN)

Complete Form SS-4, Application for Employer Identification Number.

You can also apply for an EIN online.

Forms W-7 and SS-4 can be viewed, downloaded, or printed from the IRS forms and instructions page. You can also request printed copies through the IRS forms ordering service. Mailed forms may take up to 15 business days to arrive.

How to select your federal tax classification

Choose the classification that reflects how you or your business is treated for U.S. federal tax purposes.

Individual

Enter the name shown on your tax return.
If you changed your last name without notifying the SSA, enter:

Your first name
The last name shown on your Social Security card
Your new last name

If you are applying for an ITIN, enter your name exactly as it appears on line 1a of your Form W-7 application. It should also match the name entered on the Form 1040 filed with your application.

Sole proprietor

Enter your individual name as shown on line 1 of your Form 1040.
Enter your business, trade, or “doing business as” (DBA) name on line 2.

Partnership, C corporation, S corporation, or LLC other than a disregarded entity

Enter the entity’s name as shown on its tax return on line 1.
Enter any business, trade, or DBA name on line 2.

Other entities

Enter the name shown on the required U.S. federal tax documents on line 1. This name should match the charter or other legal document that created the entity.
Enter any business, trade, or DBA name on line 2.

Disregarded entity

A business with a single owner, including an LLC that is not treated as a corporation, is generally treated as separate from its owner for U.S. federal tax purposes.

A disregarded entity should:

Select the federal tax classification of its owner.
Enter the owner’s name on line 1. Do not enter the disregarded entity’s name on this line.
Enter the disregarded entity’s name on line 2.

The name on line 1 should match the name on the income tax return where the income is reported.
If the direct owner is also a disregarded entity, enter the first owner that is not disregarded for federal tax purposes.
If the owner is a foreign person, the owner must complete the applicable Form W-8 instead of Form W-9, even if they have a U.S. TIN.

If you are unsure which TIN or federal tax classification applies to you, consult a qualified tax professional. RemoFirst cannot provide personal tax advice.
