Making Tax Digital. Made Simple.

Taxtool helps you upload your spreadsheet accounts, calculate your tax, and submit your Self-Assessment return online — fully compliant with HM Revenue & Customs and Making Tax Digital.

Tax Submission Software That Actually Works

We believe tax submission shouldn’t feel intimidating.

Taxtool focuses on:

Clarity – simple upload process
Accuracy – automated tax calculation
Compliance – aligned with current HMRC rules
Affordability – cost-effective alternative to full accounting software

You stay in control of your numbers. We handle the submission framework.

Taxtool supports tax returns for 2025/26 onwards only.
To begin with, you can submit CIS and dividend income as non-mandated income types. We’ll be adding more options over the next three months.
