Complete Tax Solutions

Complete Tax Solutions is a suite of tax compliance products for organizations with corporate and specialist tax workloads. It is best suited to Australian tax teams and advisers handling multiple entity types. Its combination of Excel-linked work and specialist tools is compelling, but custom pricing makes a product-by-product fit check essential.

Overview

This is a portfolio rather than a single application, covering corporates, tax-consolidated groups, trusts, partnerships, managed investment trusts, employee share schemes and other tax tasks. That breadth can suit an in-house team or professional services firm with varied engagements; it may be more than a buyer needs for a narrow, individual-return workflow. SW Accountants & Advisors has operated in Australia since 1935. The firm says CTS is used by private, large and listed groups in Australia and by hundreds of tax professionals in industry and professional services.

The suite is developed within Microsoft Excel and can link automatically with Excel workpapers. That makes it a natural consideration for teams whose tax calculations and supporting records already depend on spreadsheets, while buyers seeking a workflow independent of Excel should weigh that foundation carefully.

Key features

Tax reporting and returns

CTS for Corporates automates current and deferred tax calculations, tax journals and AASB 112 disclosure notes for financial statements. CTS also combines reporting with tax return preparation, with returns lodged either manually or electronically through the ATO Standard Business Reporting portal. The mix is useful for teams that want provision work and filing in one product family, rather than separate tools for those tasks.

Workpaper oversight

Task listing and monitoring, workpaper records and audit reporting help teams track reviewed figures and queries. These controls address the coordination burden of multi-person tax work; teams needing only calculation or filing may not benefit enough from the broader management layer to justify the suite.

Cloud and specialist tools

CTSplus products sit in a cloud-based tax management system, with access from anywhere, shared team information and real-time visibility of tax work. CTSplus FBT uses Microsoft Azure for secure access. Trusts, AMITs and Partnerships have desktop, network and cloud deployment options, giving those users more choice over setup.

CTS Pillar Two supports GloBE calculations, trial-balance mapping, workflow tracking, dashboards, reporting and completion and lodgement of required forms, including the GIR. CTS Data Analytics examines income tax, indirect tax, customs and superannuation to identify errors, anomalies, process deficiencies and potential savings. These specialist offerings broaden the suite beyond routine compliance, particularly for organizations dealing with Pillar Two obligations or reviewing tax processes across several domains.

Support

Training and a helpline staffed by qualified tax professionals are included at no extra cost. The CTS team says it responds to enquiries by the next business day, a useful support commitment for tax work with deadlines.

Pricing

Complete Tax Solutions is paid software with custom pricing; contact the CTS team for a quote. There is no published tier structure to compare, so organizations should establish which products, deployment options and scope their quote covers before budgeting. The suite supports electronic filing, consolidated returns, tax provision, accounting integrations and approval workflows, but pricing and entitlements should be confirmed for the selected configuration.

Platforms

CTS is available for web and Windows, with hybrid deployment. Individual product choices matter: the Trusts, AMITs and Partnerships products offer desktop, network and cloud options, while CTSplus uses a cloud-based management system. Teams should match the deployment to their access and workpaper requirements rather than assume every product shares the same setup.

Who it's for

Consider CTS if you are an Australian corporate tax team or professional adviser managing varied entities, provision and returns, and want Excel-linked workpapers plus oversight tools. Pillar Two and data analytics make it relevant to organizations with those specific needs as well. It is less clearly suited to individuals or small teams seeking a single low-cost return product, or buyers who want published prices and a simple, uniform deployment.

Pros and cons

• Pros: Broad entity and specialist-tax coverage can serve varied corporate and advisory workloads within one product portfolio.
• Pros: Excel workpaper linking, calculation automation and audit reporting connect preparation with review and oversight.
• Pros: Training and a qualified-professional helpline are included, with a stated next-business-day response target.
• Cons: Custom pricing makes cost comparisons and budgeting harder before a quote is scoped.
• Cons: Excel is central to the software, which may not suit teams seeking a standalone, non-spreadsheet workflow.
• Cons: Deployment varies by product, so buyers need to confirm the setup for each part of the suite.

Alternatives

Corporate Tax Software is the category directory for comparing corporate tax tools. Consider Alphatax if a paid option with a free trial and API, web and Windows platforms better fits your evaluation. CSC Corptax is another paid enterprise corporate tax option, with pricing handled through a requested demo. For individual returns, TaxCalc offers a paid plan at £42 a year for six returns in the 2025–26 tax year, as well as a free trial; it is a more directly scoped alternative than CTS’s corporate portfolio.

CCH Axcess Practice is worth considering when Android or iOS access alongside web is a priority; it uses quote-based pricing. IRIS Personal Tax is a paid alternative for UK tax documentation, with self-hosted, web and Windows platforms. ONESOURCE Certificate Manager may suit buyers seeking that certificate-management product, with paid pricing and a free demo request. PowerPlan Tax Provision is another paid, web-based option. Tax Series offers a free trial and API and web platforms, with licensing fees based on scope established during proof of concept.

Verdict

Choose Complete Tax Solutions if your Australian tax team needs a broad portfolio spanning provision, returns, workpaper oversight and specialist requirements, and values Excel-linked workflows. Its depth and professional support are the main reasons to shortlist it; custom pricing and product-specific deployment choices are the reasons to look elsewhere if you want straightforward costs or a single, clearly defined application.
