Tax & MTD

OffMarketLeads includes basic tax estimation tools to help you understand the tax implications of property investments. These are planning tools, not substitutes for professional tax advice.

SDLT calculator

The Stamp Duty calculator uses current HMRC banded rates, including the additional property surcharge for second homes and BTL purchases. It shows a breakdown by band so you can see exactly how the tax is calculated.

Income tax estimates

The BTL and HMO calculators include basic income tax modelling based on your marginal rate. Rental income is taxed as income in the UK — the calculators show net-of-tax cashflow.

Making Tax Digital (MTD)

MTD for Income Tax Self Assessment is being rolled out for landlords. If your property income exceeds £50,000 (from April 2026), you'll need to submit quarterly updates digitally.

OffMarketLeads doesn't currently integrate with MTD software, but exported portfolio data is compatible with common accounting packages. This is on the roadmap for a future release.

Tax calculations are estimates based on standard rates. Your actual tax position depends on personal circumstances, allowable expenses, mortgage interest relief, and other factors. Always consult a qualified accountant for tax planning.
