TaxMate: Home Office Tax
Self-Assessment Tax Calculator
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
A better way to calculate home office tax.
If you’re self-employed or run a small business, claiming home office expenses is one of the most common and most misunderstood parts of Self Assessment.
Many people default to the flat rate. Others try to calculate actual costs themselves. Both approaches can lead to under-claiming, confusion, or uncertainty.
This app helps you work out which option actually makes sense for you, clearly and calmly, in line with HMRC guidance.
Home office tax is often miscalculated because there are two HMRC-approved ways to claim home office expenses: the simplified flat rate and a detailed calculation based on actual costs. The right choice depends on how you work, how much space you use, and what your real expenses are.
This app calculates both methods, compares them side by side, and shows you the option that best fits your situation. There’s no guesswork and no assumptions.
The app calculates home office tax using both approved methods, compares flat rate versus actual costs, uses your real expenses and work patterns, and shows the difference clearly and transparently. Everything is designed to be simple and understandable, even if you’re not confident with tax.
This app is designed for self-employed individuals, sole traders, and small business owners who work from home either full-time or part-time and complete their own Self Assessment. It’s also ideal if you’re unsure whether the flat rate is right for you.
Using the app is simple. You answer a few straightforward questions about how you work, the space you use at home, and your household and business expenses. The app handles the calculations and presents the results clearly. Most people complete their calculation in just a few minutes.
Your personalised summary shows both calculation methods, which option is more beneficial, how the figure is worked out, and a clear breakdown you can save or share. This makes it easier to keep records, review your decision later, or pass the information to an accountant if needed.
The app is built with care to help you make better-informed tax decisions, not to push aggressive claims. It follows published HMRC guidance and focuses on clarity, accuracy, and confidence. The app is not affiliated with HMRC.
This app is for self-employed individuals, sole traders, small business owners, and anyone working from home who wants clarity on home office tax. It is not designed for companies claiming corporate expenses, VAT-specific calculations, payroll, or bookkeeping management.
The app does one thing and does it well. Download now and make your home office tax decision with confidence.
