We'll take care of the taxes, so you can focus on what matters.

Yes. Even if tax is being deducted at source under the NRL Scheme, you are still required to file an annual Self Assessment tax return. This allows you to declare your rental income, claim allowable expenses, and either reclaim overpaid tax or settle any additional amount owed. We manage this process for you.
You can deduct a range of allowable expenses from your rental income, including mortgage interest (subject to the 20% tax credit restriction), letting agent fees, property maintenance and repairs, insurance, ground rent and service charges. We review your expenses thoroughly to make sure you're claiming everything you're entitled to.
If you sell a UK residential property and make a profit, you must report and pay Capital Gains Tax (CGT) within 60 days of completion. As a non-resident, this applies to UK property sales regardless of whether you file a Self Assessment return. We handle the CGT calculation and submit the return to HMRC on your behalf to meet the strict deadline.
This is a common concern. The UK has double taxation treaties with many countries which means you generally won't pay full tax twice on the same income. We advise on how treaty relief applies to your specific situation and make sure any foreign tax credit is properly claimed to reduce your UK liability.
