DT7756 - Guidance by country: Georgia: relief from Georgian tax
You should check the other guidance available on GOV.UK from HMRC as Brexit updates to those pages are being prioritised before manuals.
No special forms are available in this country for claiming relief from Georgian tax under the agreement.
Persons wishing to claim relief should apply by letter addressed to the Ministry of Finance, 70, 1. Abashidze Str, 380062 Tblisi, Georgia.
The instructions in https://www.gov.uk/hmrc-internal-manuals/international-manual/intm120080 should be observed where the claimant’s United Kingdom Inspector issues a certificate of residence on request. The certificate should be signed by an Inspector and impressed with the office’s date stamp.
