Project Description
Buying a property involves far more than simply agreeing a purchase price. Stamp duty, legal fees, surveys, deposits and moving costs can significantly affect the overall budget.
UK Stamp Duty Calculator was developed to simplify this process by combining accurate property tax calculations with practical budgeting tools in a clean, modern interface.
Built specifically for UK buyers, the app supports the different tax systems used across England & Northern Ireland (SDLT), Scotland (LBTT) and Wales (LTT), allowing users to quickly compare purchase scenarios and estimate their overall buying costs.
The Challenge
Property tax calculations vary across different parts of the UK and can become increasingly complex depending on the buyer's circumstances.
Factors such as first-time buyer relief, additional property surcharges and regional tax rules make it difficult for many buyers to estimate the true cost of purchasing a home.
The challenge was to create a simple mobile application capable of handling these different calculation rules while presenting results in a clear, user-friendly format.
The Solution
UK Stamp Duty Calculator combines property tax calculations with practical planning tools designed specifically for UK home buyers.
Key features include:
- SDLT calculations for England & Northern Ireland
- LBTT calculations for Scotland
- LTT calculations for Wales
- First-time buyer support
- Additional property surcharge calculations
- Buy-to-let planning
- Detailed tax band breakdowns
- Property purchase comparison tool
- Budget planner for upfront costs
- Save estimates locally
- PDF export (Pro)
- Offline-first functionality
Every calculation is presented using easy-to-read summaries and tax band breakdowns, helping users understand exactly how their estimated property tax has been calculated.
