inheritance and its potential tax implications

Dear HMRC Community Center, I hope this message finds you well. I am writing to seek guidance and clarification regarding a financial matter that involves my recent inheritance and its potential tax implications. I was born in Iran and currently hold a UK visa with refugee status valid until 2027. Approximately one year ago, I inherited properties in Iran with an estimated total value of £300,000. I want to sell these properties and invest the proceeds in property in the UK. To provide context, the inheritance tax for these properties has already been paid in Iran, and I have all the necessary legal documents confirming the inheritance. Given this situation, I have several questions: What specific documents will I need to provide when transferring the proceeds from the sale of these properties to the UK? Are there any tax obligations or liabilities in the UK that I need to be aware of when receiving this inheritance money? Due to sanctions on Iran, I must use FCA regulated money transfer agencies for this transaction. These agencies have informed me that they can provide a letter confirming the source of the funds. Will this documentation be sufficient for tax and legal purposes? I greatly appreciate your assistance in clarifying these matters. Your guidance will help me ensure that I am in compliance with all relevant tax regulations and requirements in the UK. Please let me know if there are any additional details or documents that I should be aware of or provide. Thank you for your time and support. I look forward to your response. Sincerely,

Hi Amir Ali,
1. You may wish to call our Inheritance Tax helpline re: any possible UK Inheritance Tax implications :
Inheritance Tax: general enquiries                                                    
2. As regards the sale of the inherited properties, as a UK resident you are potentially liable to Capital Gains Tax.
Please refer to the following guidance:
Tax when you sell property                                                                          
3.  There are no Income Tax implications re: the transfer of funds from Iran to the UK, and you are not required to provide HMRC with any supporting documentation.      
Thank you.
