Is it normal for the Thai embassy to request HMRC tax returns for my visa application?

The Thai embassy's request for HMRC tax returns can be concerning, especially for those who believe they are tax exempt due to residing in the UK for less than 90 days. Contributors suggest communicating your non-resident status to the embassy, possibly including any official documents that support your claim. This request might be aimed at verifying your income or financial stability, especially given the information provided in your visa application. Some members express confusion over the expectation of tax records from a country of which they may not have been actively involved for years, suggesting a letter of explanation could also be beneficial.
