What Is a Certificate of Tax Residence?
A Certificate of Tax Residence is an official tax administration document confirming residence for treaty relief, issued under procedures set by national law.
Also known as: tax residency certificate, certificate of residence.
How Certificate of Tax Residence works
A Certificate of Tax Residence is issued by a tax administration on request to confirm that a person or entity is resident there for tax purposes, and foreign payers or tax authorities generally require one before applying a reduced treaty withholding rate or granting double taxation relief. HMRC, for example, issues a certificate where the applicant is UK resident and a double taxation agreement exists with the country concerned, and declines where treaty benefits are not available. In the United States, Form 6166 certifies residency after an application on Form 8802 and may also support a foreign VAT exemption claim. Certificates usually cover a specific period, and eligibility, format and processing differ by country.
Certificate of Tax Residence vs Tax Residency
Unlike tax residency, which results from legal tests applied to facts, a certificate of tax residence is evidence issued by one administration and does not bind another state applying its own tests.
Example
Illustrative example: A consultant resident in Country A invoices a client in Country B, where domestic law withholds tax on service fees paid abroad. The treaty between Country A and Country B reduces that withholding, but the client's tax office asks for proof of residence. The consultant obtains a certificate from Country A covering the relevant year, and the client applies the treaty rate, while Country B remains free to examine whether the consultant also meets its own residence tests.
Common misconception
Myth: Obtaining a tax residency certificate from a new country ends tax residence in the country left behind.
Reality: A certificate of tax residence confirms status under the issuing country's rules only, so the former country applies its own residence tests and, for dual residents, a treaty tie-breaker decides treaty residence.

A Certificate of Tax Residence is an official document issued by a tax administration confirming that a person or entity is resident there for tax purposes, generally used to claim treaty benefits such as reduced withholding.
Does a tax residency certificate prove I am not resident elsewhere?
A Certificate of Tax Residence proves residence only under the issuing country's rules; another state may still treat the holder as resident, in which case the applicable double tax treaty tie-breaker generally determines treaty residence.
