Frequently Asked Questions
Do I need a property accountant for one rental property in London?
Even with a single property, a specialist accountant ensures every allowable expense is claimed, mortgage interest relief is calculated correctly under Section 24, and your Self Assessment is filed on time. Most landlords recover the fee through the tax savings identified in the first year.
How much does a property rental accountant in London cost?
Fixed fees typically start from 199 pounds plus VAT for a single property Self Assessment and rise based on the number of properties, joint ownership, and whether the property is held in an SPV. We provide a written quote before any work begins.
Should I hold my buy to let in a limited company or personal name?
It depends on your marginal tax rate, mortgage profile, and exit plans. We model both scenarios, including incorporation costs, SDLT on transfer, and ongoing Corporation Tax, so the decision is based on numbers rather than assumptions.
What expenses can I claim against rental income?
Letting agent fees, repairs and maintenance, ground rent and service charges, landlord insurance, accountancy fees, and 20 percent of mortgage interest as a basic rate tax reducer. Capital improvements are not deductible against income but reduce your future CGT bill.
Do non resident landlords need a UK accountant?
Yes. Without an approved NRL1 application, your letting agent or tenant must withhold 20 percent basic rate tax from your rent. We handle the application, file the annual Self Assessment, and reclaim any overpaid tax from HMRC.
When is the deadline for reporting a property sale to HMRC?
Capital Gains Tax on UK residential property must be reported and paid within 60 days of completion via the HMRC online CGT service. Late filings attract penalties and interest.
Can you help with HMRC’s Let Property Campaign?
Yes. We prepare voluntary disclosures, calculate the tax, interest, and reduced penalties, and liaise with HMRC on your behalf to bring undeclared rental income up to date.
Do you support Making Tax Digital for landlords?
Yes. We onboard landlords onto MTD compatible software, set up quarterly digital records, and prepare the end of period statement and final declaration ahead of the April 2026 rollout.
