Complete Tax Solutions is a portfolio of tax compliance products covering corporate reporting, returns and specialist tax work. It is best suited to Australian corporate tax teams and advisers working across several entity types. Its Excel-linked workflows and range of tools are compelling for complex work, but the right product and deployment need to be matched to each team’s requirements.

Overview

Rather than one application, CTS spans corporates, tax-consolidated groups, trusts, partnerships, managed investment trusts, employee share schemes and other tax tasks. That breadth can serve in-house departments and professional firms with varied engagements; it is less compelling for a buyer seeking a narrow, standalone tax-return tool. SW Accountants & Advisors has operated in Australia since 1935 and says CTS serves private, large and listed groups, as well as hundreds of tax professionals in industry and professional services.

Built within Microsoft Excel, CTS can link automatically with Excel workpapers. That is a practical fit for teams whose calculations and supporting records already live in spreadsheets, though buyers wanting a workflow independent of Excel should weigh this foundation before choosing.

Key features

Reporting, returns and workpapers

CTS for Corporates automates current and deferred tax calculations, tax journals and AASB 112 disclosure notes. CTS also brings reporting and return preparation together, with returns lodged manually or electronically through the ATO Standard Business Reporting portal. Electronic filing, consolidated returns and tax provision support make the suite relevant to teams with recurring corporate obligations, not just one-off preparation needs.

Task monitoring, workpaper records and audit reporting help teams track reviewed figures and outstanding queries. Approval workflows and accounting integrations are also supported. These controls can help coordinate review across a team, but they do not remove the need to choose the product that covers the relevant tax task.

Cloud and specialist products

CTSplus products use a cloud tax management system for access from anywhere, team information sharing and real-time visibility of tax work. CTSplus FBT provides secure access with Microsoft Azure. Trusts, AMITs and Partnerships products have desktop, network and cloud deployment options, giving buyers a choice of setup for those workloads.

For multinational groups facing Pillar Two obligations, CTS Pillar Two supports GloBE calculations, trial balance mapping, workflow tracking, dashboards and reporting, as well as completion and lodgement of required forms including the GIR. CTS Data Analytics addresses income tax, indirect tax, customs and superannuation, identifying errors, anomalies, process deficiencies and potential savings. These specialist capabilities widen the suite’s appeal, though buyers should confirm that the selected CTS product covers their particular scope.

Training and a helpline staffed by qualified tax professionals are provided at no extra cost, with CTS saying it responds to enquiries by the next business day. That support can matter to teams handling technical tax work without a large internal support function.

Pricing

Complete Tax Solutions is paid software with custom pricing. The CTS team should be contacted for a quote. With a portfolio spanning distinct products and deployment choices, buyers should establish which modules and setup their work requires before comparing costs.

Platforms

CTS supports web and Windows, with hybrid deployment. Cloud, network and desktop choices are described for Trusts, AMITs and Partnerships; CTSplus products are cloud-based. The deployment options are useful for organizations with differing infrastructure needs, but should be checked against the specific product under consideration.

Who it's for

CTS is a strong candidate for Australian corporate tax departments and professional advisers managing reporting, returns and workpapers across multiple entities. Its specialized Trusts, AMITs, Partnerships, FBT, Pillar Two and analytics tools can also suit teams with those defined needs. Buyers focused on a simpler or narrower workflow should compare the scope and custom quote with a more targeted product.

Pros and cons

  • Broad tax coverage: Corporate reporting and returns sit alongside tools for specialist entities, Pillar Two and tax data analytics.
  • Excel-linked work: Automatic links to Excel workpapers suit teams already organized around spreadsheets, but make the Excel foundation central to product fit.
  • Flexible choices for some products: Trusts, AMITs and Partnerships offer desktop, network and cloud options; the same choices should not be assumed for every product.
  • Tax-professional support: Training and a helpline are included at no extra cost, with a next-business-day response target.
  • Custom pricing: A quote is required, so buyers cannot compare a public price before specifying their product needs.

Alternatives

Corporate Tax Software is the category directory for buyers comparing corporate tax tools more broadly.

  • Alphatax is worth comparing if a free trial is important; it is paid and supports API, web and Windows platforms.
  • CCH Axcess Practice may suit buyers prioritizing Android or iOS access alongside web; it is paid and quote-priced.
  • CSC Corptax is another paid web-based corporate tax option, with pricing by requested demo.
  • PowerPlan Tax Provision is a paid web-based alternative.
  • Tax Series is worth considering if a free trial is useful; it is paid, supports API and web, and its licensing fee depends on scope determined during proof of concept.
  • TaxLab Nucleus is a paid web-based alternative.
  • Bloomberg Tax may suit buyers seeking a paid web suite spanning tax provision, workpapers, fixed assets, tax research, corporate tax analysis, income tax planning and payroll research; pricing is by contacting sales.
  • ONESOURCE Tax Provision is a paid option with web and API platforms and pricing through sales.

Verdict

Choose Complete Tax Solutions if your Australian tax team needs linked corporate reporting, return preparation and workpaper controls, or specialist tools across several tax areas. Its combination of Excel-connected work, cloud management and professional support is the main reason to consider it. Look elsewhere if you need a simple, independently priced product or a workflow that does not center on Excel; CTS requires a custom quote and a product-level fit decision.

Verdict

Complete Tax Solutions offers distinct tools for tax reporting, returns, cloud tax management, Pillar Two work, and data analytics. Buyers should ask the CTS team about pricing and which deployment choices apply to their selected products.
