Know what your property really returns
Track your returns live and prepare box 3 or corporation tax with figures that add up — built automatically from your rent and cost flows. No more loose spreadsheets.
Your financial dashboard
All rental income, costs and payments come together in one dashboard. Per property and across your whole portfolio you see what comes in, what goes out and what is left at the bottom line.
Because the figures come straight from your invoicing and costs, they are always current — with nothing to retype. The underlying administration — bank feed, costs by category and the reporting suite — feeds this dashboard.
- ✓ Gross and net return per property
- ✓ Income and costs in one place
- ✓ An overview of the whole portfolio
- ✓ Always current, updated automatically
Box 3 vs corporation tax — a switchable model
Box 3 (private)
Letting as a private individual? Protiva works with the deemed-return box 3 model and prepares the figures for your return on an indicative basis.
Corporation tax (business)
Is your property in a company? Then Protiva switches to corporation tax and keeps the relevant items separate.
The tax calculations are indicative and based on the rules in force at the time (reference date 2026). This is not tax advice; your tax adviser remains in the lead for your return.
Calculate your return

Frequently asked questions
How does Protiva calculate my return?
Protiva combines your rental income with the costs you record — maintenance, management, insurance, financing — and sets them against the value of your property. That gives you gross and net returns per building and across your whole portfolio, updated automatically.
What is the difference between box 3 and corporation tax?
Private individuals with property normally fall under box 3 (income tax on wealth), whereas property held in a company falls under corporation tax. Protiva uses a switchable model that calculates per account type and prepares the figures on an indicative basis. It is not a tax return, nor tax advice.
Does this replace my accountant?
No. Protiva delivers figures that add up and are ready to share with your accountant or adviser, so the groundwork is done. The tax calculations are indicative; for your final return your adviser remains in the lead.
