Gbooks review
A practical choice for firms filing UK SA100 returns at higher volume.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Gbooks is browser-based UK tax and accounts compliance software for accountants and their staff. Its personal tax module focuses on creating Personal SA100 tax returns, supporting supplementary pages except MPs, filing online to HMRC, and producing tax calculations and PDFs. Online client and return status tracking gives accountancy firms a way to monitor work across multiple clients. The wider suite also covers partnership and company tax, accounts production, VAT filing, practice management, client bookkeeping and Companies House filing, making it more suitable for firms than individual taxpayers.
The personal tax plans are priced by annual return capacity. The 25-return license costs £125 per year, the 50-return license costs £225 per year, and the Unlimited license costs £275 per year. The plans list Personal SA100 tax returns as their core inclusion, while the product notes that prices exclude VAT. A 30-day no-obligation trial is available, and the service is paid rather than free. For firms handling more than 50 returns, the Unlimited tier has the clearest pricing rationale; smaller practices can match the license to their expected volume.
Its strongest workflow coverage is around return preparation and submission: data validation, short and detailed calculations, amended returns, file attachments and online HMRC filing are all included. Integration with HMRC and Companies House supports a UK compliance workflow, while cloud deployment avoids local installation. Support is available by email and phone, although support is not listed as 24/7. Gbooks should suit small and mid-market accountancy firms that want a web-based system for recurring UK returns and broader compliance work. It is less suitable for users who require mobile access, 24/7 support or supplementary-page coverage for MPs.
