eSTM Pty Ltd is a Sydney-based research and software company focused on Australian investment taxation, especially capital gains tax (CGT) calculations, corporate action databases, and reconstruction of tax cost bases for investment portfolios. Its core products include Securities Tax Manager (STM) and the CGTView data portal. According to its website, its products are used by Australian accounting and financial market organizations, and the company has been operating since 1993.
STM focuses on automatically maintaining equity investment portfolios and optimizing CGT liabilities for the current tax year. Its portfolio reconstruction service is aimed at accountants. When transaction history is incomplete, it can use known transactions, holdings, dividend reinvestment plans, and other available records, together with eSTMβs ASX and managed fund corporate action databases, to rebuild the tax cost base and produce unrealized holding reports. For deceased estate scenarios, the system can maintain funds at the date of death, manage estate holdings through to distribution, and allocate tax parcels proportionally to beneficiaries based on how securities are transferred and registered.
The official website does not disclose plans, pricing, a free version, or trial information, so purchasing will most likely require contacting the sales or service team. In terms of integrations, the site mentions that eSTM is developing a cloud-based solution that combines STM and CGTView into a single application, supports connections to external data sources, automates portfolio maintenance, and allows STM tax data to integrate with external systems. However, it currently does not provide details on APIs, developer documentation, specific third-party systems, or launch status.
Its main strength is its highly focused vertical specialization: it is deeply oriented toward Australian CGT calculations and has corporate action data going back to 1985, making it suitable for complex tax work such as cost base reconstruction, deceased estates, and beneficiary allocations. The main risk is limited transparency: pricing, deployment model, security certifications, permission-based collaboration, and API capabilities are not described in detail. The product is also clearly designed around the Australian tax system, so it is not suitable as a direct solution for Chinese capital markets taxation or general finance and tax management needs.
It is better suited to Australian accounting firms, financial institutions, estate administration teams, and specialist investment tax service providers that require accurate CGT reporting. Access from China is unknown, and payment methods are not disclosed. If your business does not involve Australian tax matters, it is advisable to prioritize local finance/tax or asset management systems, or domestic alternatives such as Kingdee and Yonyou.
