How to Get Your ITIN Number in Florida – Straight Advice for Resident & Non-Residents

Man, if you’re living outside the US but you own a place in Miami, Orlando, Tampa or anywhere in Florida, or you’re thinking about starting a business here, you’re probably gonna need an ITIN number sooner or later.

  • ITIN means Individual Taxpayer Identification Number
  • It is a 9-digit tax number
  • The Internal Revenue Service (IRS) gives it to people who cannot get a Social Security number
  • It is used for tax purposes in the United States
  • Every ITIN starts with 9

That’s it — nothing more. It doesn’t let you work here, get benefits, or anything like that. Just helps you file your taxes right.

I’ve had friends from all over — Colombia, India, Europe, you name it — hit this wall after buying a rental condo on the beach or setting up a small company. They start earning rent money or sell a property and the IRS wants their paperwork. Without the ITIN, you can’t file properly and your refunds get stuck.

ITIN vs SSN – They’re Totally Different

People always ask me this.

SSN is for Americans and folks who can legally work here. It’s tied to jobs, Social Security checks, driver’s licenses, all that.

ITIN is only for taxes. If you’re a foreign owner, this is what you put on your personal tax forms. Don’t confuse the two — they do completely different jobs.

ITIN vs EIN – Another Common Mix-Up

Same thing with EIN.

Your ITIN is personal — it belongs to you.

Your EIN is for the business, like your Florida LLC. You use the EIN for the company’s bank account and some filings.

If you have a single-member LLC as a non-resident, the income usually flows straight to you. So you report it on your own tax return using your ITIN. Most people end up needing both numbers, but they are not the same.

Starting a Florida LLC as a Foreigner

Florida is still one of the better states for outsiders to set up a company. No state income tax on personal earnings is a big plus.

You file the papers online at Sunbiz. The big requirement is you must list a registered agent who has a real street address in Florida — no PO boxes allowed.

A lot of foreign owners don’t want their own name and address public, so they pay for a registered agent service. These guys accept legal papers and government notices for you. It’s not expensive and it saves a ton of stress when you’re not living here full time.

What Does a Registered Agent Actually Do?

They’re the official contact for your LLC. If someone tries to sue the company or the state sends tax papers, it goes to the registered agent first. They have to be available during normal business hours at a physical Florida address.

Using a service means your personal info stays private and someone is always there to handle the mail. You can switch agents anytime if you want.

Florida Annual Report – Pay Attention to This

Every year your Florida LLC has to file an annual report. The deadline is May 1 every year. For 2026, you must file by 11:59 PM on May 1, 2026 or you get hit with a $400 late fee immediately.

The normal fee is $138.75. It’s all done online at Sunbiz.org. You just update your info, confirm the registered agent, and pay. A lot of registered agent services will file it for you so you don’t forget and lose your company.

Miss it long enough and the state can dissolve your LLC. Not worth the risk.

How to Get an ITIN Number – What Actually Works

Here’s the real process most people follow:

First, you need a reason — usually because you have a tax return to file (like 1040-NR for non-residents).

You fill out IRS Form W-7. Take your time on this one.

Next, you need proof of who you are. A current passport is the easiest — it covers both identity and that you’re foreign. If you don’t have a passport, you’ll need a couple of other certified documents from the IRS list.

You attach your tax return to the W-7 and send the whole package to the IRS. You can mail it, go in person to certain IRS offices (you need an appointment), or use a Certifying Acceptance Agent who checks everything for you.

Right now in 2026, it normally takes 7 to 11 weeks. During busy tax season it can run longer, especially if you’re applying from outside the country.

Once approved, the IRS mails you a letter with your new ITIN.

Extra Tips for Non-Residents

  • Apply when you actually have taxes to file. Sending it too early without a return usually gets kicked back.
  • Make copies of everything before you send it.
  • The IRS doesn’t charge any fee for the ITIN itself. Be careful with companies that want big money just to help fill the form.
  • If you’re in Florida even for a short time, try to book an IRS appointment — you can often get your original documents back the same day.

How to Find Your ITIN Later

If you already have one but forgot the number, dig up old tax returns or IRS letters. You can call the IRS too, but have your ID ready. Never guess the number on any form.

How Most Guys Put It All Together

A clean setup usually looks like this:

  • File your Florida LLC on Sunbiz
  • Hire a solid registered agent service
  • Get an EIN for the LLC
  • Apply for your personal ITIN
  • Make sure the annual report gets filed every year before May 1

Do it right and you stay out of trouble while you focus on your properties or business.

Florida gets a lot of international investors — Miami, Orlando, Tampa, Jacksonville — all full of people in the same boat. The ones who handle the ITIN and LLC paperwork early always sleep better at night.
