A tax residency certificate (TRC), also called a certificate of residence or certificate of fiscal residence, is an official letter from a country's tax authority confirming that you were a tax resident there for a given year. It's a one-page document, but if you've moved countries, own a company abroad, or receive dividends from another country, it's often the most important tax paper you have.
Moving somewhere isn't enough. You need to be able to prove where you're resident, and the TRC is the standard proof that tax authorities, banks, and payers accept.
What is a tax residency certificate used for?
| Use | Why the certificate matters |
|---|---|
| Claiming treaty benefits | Double tax treaties cut withholding tax on dividends, interest, and royalties, often from 25–35% to 0–15%. The payer or foreign tax office needs proof that you're resident in the treaty country. |
| Proving you've left your old country | When you emigrate, your former country may keep treating you as resident. A TRC from your new country is key evidence, and treaty tie-breaker rules start from it. |
| Banks and CRS | Under the Common Reporting Standard, banks have to collect your tax residence. A TRC supports your self-certification, especially if you claim residence in a low-tax country. |
| Company substance | Companies use corporate TRCs to claim treaty rates and to show where they're managed. |
| Payment platforms and clients | Some platforms and clients ask for it before paying without withholding. |
The certificate usually covers one calendar or tax year, so you request a new one each year.
How do you get a tax residency certificate in the US? (Form 8802 / Form 6166)
US residents, including US citizens living in the US and US LLC owners who qualify, get Form 6166 by filing Form 8802 with the IRS.
- Fee: $105 for individuals and $230 for entities, for applications postmarked on or after October 1, 2026 (previously $85 and $185). The fee is per application, so request all countries and years on one form.
- Timing: apply at least 45 days before you need it. Payment goes through Pay.gov.
- Catch: a foreign-owned single-member LLC is disregarded for US tax and generally can't get Form 6166 in its own name. That's a common problem for non-US founders who expect treaty benefits from a US LLC. See LLC for non-US residents.
How do you get one in the UK?
HMRC issues certificates of residence online through its apply for a certificate of residence service. Individuals sign in with their Government Gateway account, and postal applications are still possible. There's no fee. Online applications are usually handled within a few weeks. HMRC can only issue one if you're UK resident under the Statutory Residence Test for the year in question. Some countries' forms also need HMRC certification on their own template.
How do you get a UAE tax residency certificate?
The UAE has no personal income tax, but it has 70+ tax treaties. A UAE TRC from the Federal Tax Authority is how residents of Dubai and Abu Dhabi prove where they live.
- Where: online through EmaraTax.
- Fee: AED 1,000 for an individual without a corporate tax registration number (AED 500 with one), plus a small application charge. Hard copies are extra.
- Timing: about 5 working days once the application is complete. Valid for one year.
- Residency rules for individuals (from Cabinet Decision No. 85 of 2022, in force since 1 March 2023), any one of:
- physically in the UAE for 183 days or more in a 12-month period, or
- 90 days or more in 12 months, and a UAE national, GCC national, or UAE residence-visa holder who also has a permanent place of residence or a job or business in the UAE, or
- your usual or primary residence and centre of financial and personal interests are in the UAE.
- Documents: passport, Emirates ID and residence visa, an entry and exit report from immigration, a tenancy contract or title deed, six months of local bank statements, and proof of income or employment.
In practice, if you need the certificate to claim a treaty benefit, plan for 183 days. The 90-day route works for domestic purposes, but foreign tax authorities may not accept it, and EmaraTax asks which treaty the certificate is for. See the UAE country page.
How do you get one in Portugal, Estonia, Cyprus and Singapore?
| Country | Authority and route | Cost | Notes |
|---|---|---|---|
| Portugal | Portal das Finanças → Cidadãos → Serviços → Certidões → Residência fiscal | Free | Usually issued instantly. Valid for the fiscal year requested. Treaty-ready without a stamp. |
| Estonia | Tax and Customs Board (e-MTA) self-service | Free | You must be registered as resident (address in the population register). E-residency alone doesn't make you a tax resident. |
| Cyprus | Tax Department, Form T.D.126 | Small fee | Issued under the 183-day rule or the 60-day rule: 60+ days in Cyprus, no other country of residence for 183+ days, a home in Cyprus, and a Cyprus job, business, or directorship. Takes a few weeks. |
| Singapore | IRAS via myTax Portal | Free | Based on 183+ days in Singapore, or employment there. |
Most EU countries offer similar online services. Many will also stamp a foreign tax authority's own form (for example a German or French withholding refund form) instead of issuing their own certificate.
What if you can't get a tax residency certificate anywhere?
This is the perpetual traveller problem. If you spend fewer than 183 days everywhere and have no home base, you might not be a tax resident anywhere. That sounds attractive, but in practice:
- Banks have to report you somewhere. CRS forms ask for your tax residence. "None" is usually rejected. Banks may then report your account to the country of your passport or last address, or close it.
- Treaty benefits disappear. Without a TRC, dividends and interest are hit with full withholding tax at source, often 25–35%.
- Your former country can still claim you. Germany treats you as resident if you keep a home available there. Spain presumes residence if your spouse and minor children stay. Many countries say you remain resident until you've established residence elsewhere. Without a TRC from somewhere new, you have no counter-evidence.
- US citizens are taxed by the US regardless, so being "nowhere" doesn't help them. See the foreign earned income exclusion.
The practical fix is to choose a base where getting residence and a TRC is realistic and low-cost: the UAE (183 or 90 days), Cyprus (60 days), Paraguay or Panama (territorial systems), or Georgia. Get the certificate every year and keep the day-count evidence behind it. Our 183-day rule guide explains how countries actually decide residence, and the digital nomad taxes guide covers people on the move.
Example: what one certificate is worth
A German founder moves to Cyprus and keeps a minority stake in his old German company. It pays him a €100,000 dividend.
- Germany withholds 26.375% at source (25% plus solidarity surcharge): €26,375.
- Under the Germany–Cyprus treaty, the rate for a portfolio dividend to a Cyprus resident is 15%.
- He files a refund claim with Germany's Federal Central Tax Office (BZSt). The claim form has to be certified by the Cypriot tax authority, or come with a Cyprus certificate of residence.
- Refund: €11,375. As a Cyprus non-dom, he pays no Cypriot tax on the dividend.
The same certificate is his main evidence if the German tax office questions whether he really left. Without it, he gets no refund and has a weaker defence.

Frequently asked questions
What is a tax residency certificate?
An official document from a country's tax authority confirming that a person or company was resident there for tax purposes in a specific year. It's mainly used to claim reduced withholding tax under double tax treaties and to prove your residence to banks and to other tax authorities.
How many days do I need in the UAE for a tax residency certificate?
Generally 183 days in a 12-month period. A 90-day route exists for UAE or GCC nationals and residence-visa holders who also have a permanent home or a job or business in the UAE. For treaty purposes, most advisers plan for 183 days.
How much does Form 6166 cost?
Form 6166 is requested with Form 8802. For applications postmarked on or after October 1, 2026, the user fee is $105 for individuals and $230 for entities, per application. Apply at least 45 days before you need the certificate.
Can a foreign-owned US LLC get a US tax residency certificate?
Usually not in its own name. A single-member LLC owned by a non-US person is disregarded for US tax and isn't a US resident for treaty purposes, so the IRS generally won't issue Form 6166 to it. A multi-member LLC taxed as a partnership is certified only to the extent its owners are US residents.
Is a tax residency certificate the same as a residence visa?
No. A residence visa or permit lets you live in a country. A tax residency certificate confirms you're taxable there under its tax rules, which usually depend on days spent, a home, or your centre of interests. You can hold a visa without qualifying for a tax certificate.
