Rent a car outside UK

I'm a director of ltd company. Sometimes I will rent a car on Italy. I can insert rent invoice on cost and reduce tax liability?

Hi Luca Scida',
Please see HMRC's Business income manual for detailed information about what expenditure can be claimed against trading income.  
Business Income Manual BIM40000 onwards is appropriate.  
Otherwise, you will need to seek the advice of a professional accountant.
Thank you.
