UK and Italian Tax Obligations for Rental Income

Hello, I became a UK resident in August last year and have a job here, which is my primary source of income. Additionally, I own a property in Italy that I rent out. According to the double taxation treaty, I believe I need to report my rental income to both the UK and Italian tax authorities. I also understand that I can claim a credit for the tax paid in Italy against my UK tax liability. However, I’m unsure how to handle the first four months of the year, considering the Italian tax year ends in December, while the UK tax year extends to April. Should I calculate the Italian tax for this period, given that the rate is known, and use it as a credit against my UK tax, even though it hasn’t been paid yet? Thank you,

Hi Enrico Giannelli,
Please refer to Tax on foreign income this covers if your income is taxed in more than one country and you haven’t yet paid tax on the foreign income. 
Thank you.
