Tax SaaS tool for preparing income tax returns for self-employed professionals and sole proprietors

A tax software tool, developed by tax professionals with years of experience, guides self-employed individuals and sole proprietors through a digital, step-by-step questionnaire to help them prepare their income tax returns. In the background, tax decision logic is applied to topics such as revenue and expenses, balance sheet and income, personal withdrawals/deposits, investments and depreciation (including the small-scale investment deduction), inventory, car benefit, and VAT reconciliation. The entrepreneur’s input is translated into structured output to prepare the tax return.

Market and Customers
The tool targets the Dutch self-employed/sole proprietor market, specifically entrepreneurs with a straightforward tax situation who do not use accounting software year-round but need structure around tax filing time. In addition, the tool is attractive to parties with access to this target group—such as accounting and tax filing firms, accounting software providers, banks/fintechs, and entrepreneur platforms—who can deploy the tool as a white-label offering or add-on. The software can easily be adapted for use by general partnerships (VOFs) and professional partnerships.

’s StrengthsThe core value lies in the tax product structure: the translation of practical tax knowledge into an easy-to-understand digital question flow, including the sequence of questions, follow-up logic, and links to the relevant tax rules. The software is a fully functional, tested full-stack application (multilingual: Dutch/English) with payment integration and PDF export. The tool addresses an annual need, enabling repeat use.
