Thanks for your question.
Can you confirm that you what you applied for and received was a Registration Certificate confirming your right of residence in the UK please?
That's a workers registration certificate which confirms that you can and are registered to work in the UK. It does not mean that you have permanent residence in this country, although as a national of an EEA member state you do of course have the right to exercise your treaty rights by staying and working here.
It does not revoke your citizenship of Latvia. Even if you were to eventually apply for permanent residence of the UK (ie. effectively Indefinite Leave to Remain for EEA citizens) your Latvian Citizenship would remain in tact.
The only circumstance in which it may be revoked by the Latvian government is if after having attained Permanent Residence you then applied for and then were naturalised as a UK citizen, but this would only happen if the Latvian Government does not permit Latvian citizens to hold dual passports.
I can't comment on the Latvian government's policy on tax collection because this is a UK law forum and there are no Latvian solicitors here.
