What is Section 24 for UK landlords?

Section 24 prevents individual landlords from deducting mortgage interest from rental income before calculating tax. Instead, landlords pay tax on full revenue and receive a 20% tax credit on mortgage interest.

Why do many UK property investors use a Special Purpose Vehicle (SPV) Limited Company?

Limited companies are exempt from Section 24 rules, allowing 100% of mortgage interest to be deducted as a legitimate business expense before paying 19%–25% Corporation Tax.
