ITIN for Spanish residents: how to get a U.S. ITIN from Spain

Do people in Spain need an ITIN?

Only if there is a U.S. tax reason. An ITIN is a nine-digit IRS number for people who need a U.S. taxpayer ID for federal tax purposes but cannot get an SSN. Living in Spain is not a reason by itself.IRS

These are the situations that usually create a reason, in any country:

• You rent out or sell a U.S. property. Foreign sellers often need an ITIN to claim FIRPTA withholding back.IRS
• You have U.S. income that needs a U.S. return, or tax was withheld that you want back.IRS
• You want a treaty rate on U.S. income and the payer needs a taxpayer ID.IRS
• You are the spouse or dependent of a U.S. citizen or resident and are claimed for an allowable tax benefit.IRS
• You are a non-resident student, professor or researcher with a return or an exception to claim.IRS

An ITIN does not give you work authorization or eligibility for Social Security benefits.IRS Our what is an ITIN guide has the basics.

What is specific to Spain

The OECD says the Spanish TIN has nine characters. For Spanish nationals it is generally the national identity card (DNI) number, and for others it is generally the Foreigners' Identification Number (NIE).OECD The tax ID you enter on Form W-7 line 6b, and on Form W-8BEN, is your NIF (for Spanish nationals the DNI number, for foreigners the NIE).OECD

• Which number you have depends on nationality. A Spanish national normally uses the DNI number and a non-Spanish resident the NIE.OECD
• Treaty claims. The U.S.–Spain treaty is on the IRS list, so a W-8BEN can claim a treaty rate where the treaty provides one.IRS

The U.S.–Spain tax treaty

The IRS lists a United States income tax treaty with Spain.IRS Under these treaties, residents of the other country are taxed at a reduced rate, or are exempt from U.S. tax, on certain items of income from U.S. sources. The items and rates vary by treaty.IRS

You usually claim a treaty rate by giving the payer a Form W-8BEN. To claim certain treaty benefits you must give either a U.S. taxpayer ID on line 5 or your home tax ID on line 6, and an ITIN is generally required if you claim treaty benefits and give no home tax ID.IRS Some treaty claims on Form W-7 are one of its reasons (box a), with an exception number and the treaty article.IRS

Your W-8BEN guide shows each line. The IRS publishes the full list on its treaties A to Z page. This is general information, not tax advice.

How to get an ITIN from Spain, step by step

Five steps, in order. You can do all of them from home.

1. 1

   Confirm your U.S. tax reason

   Most first-time applicants attach a U.S. return (Form 1040-NR). A few reasons qualify for an exception that lets you apply without one.IRS The reason you tick on the form has to match your paperwork.
