Our verdict on SA2000
SA2000 is desktop tax-return software for individuals completing UK Self Assessment returns and tax agents managing client filings. It runs on a Windows PC with Microsoft Excel, allowing users to download and complete returns offline before submitting them electronically to HM Revenue & Customs. The product covers supplementary income sections, capital gains, interest and dividends, and other Self Assessment income types. Its focus is practical rather than broad: it is designed for UK return preparation, calculations and filing rather than general personal finance management.
Pricing is straightforward. The Individual Pay as you go plan costs £14.99 as a one-time payment and includes individual Self Assessment tax-return software; a special code permits use for one return. The Individual Unlimited use plan costs £300 as a one-time payment and supports unlimited use. The published pricing covers the 2025-26 tax year, and the unlimited-use individual price is stated as £300 plus VAT. Both plans center on return preparation, while the main difference is the permitted usage level. For a single filer, pay-as-you-go keeps the upfront cost low. Unlimited use is aimed more naturally at professional users or anyone handling repeated returns.
SA2000’s standout feature is its offline Excel workflow. Users can prepare returns without working continuously in a browser, use capital gains working sheets and loss tracking, maintain interest and dividend supporting lists, and review tax-liability and payment-on-account calculations before filing. Return amendment support adds value when a submitted position needs correction. The trade-off is a narrow deployment model: the product requires Windows and Microsoft Excel, with no mobile access listed. It also does not suit users seeking a free plan, browser-first access, or a broader rental-income workflow. Choose SA2000 for structured offline UK filing; choose an alternative if those constraints outweigh Excel-based preparation.
