Overview

TaxCalc is one of the most popular tax compliance platforms among UK accounting firms, and for good reason. It handles self-assessment, corporation tax, partnership returns, and VAT with impressive depth. The interface has been steadily modernised, and the MTD support is solid.

What sets TaxCalc apart is the combination of comprehensive HMRC filing capabilities with genuinely useful features like automatic tax calculations, data validation, and the ability to handle complex scenarios that simpler tools cannot. The corporation tax module is particularly strong.

The recent cloud developments mean you can access TaxCalc from anywhere, though some firms still prefer the desktop version for its speed with large volumes of returns.
