Tax planning has shifted from a seasonal add-on to a year-round advisory service for accounting firms and financial advisors. The right software can help professionals model scenarios, identify savings opportunities, document recommendations, and communicate strategies in a client-friendly way. For firms building or expanding advisory services, choosing a platform depends on client complexity, workflow, integrations, and the depth of tax strategy support needed.
TLDR: The best tax planning software helps firms move beyond compliance by turning tax data into proactive advice. For example, a firm serving 300 business-owner clients might use planning software to identify the top 20% of clients with the largest savings opportunities and create targeted year-end strategies. Platforms such as Corvee, Holistiplan, TaxPlanIQ, Intuit ProConnect Tax Advisor, Planner CS, CCH solutions, and Drake Tax Planner each serve different firm sizes and advisory models.
1. Corvee Tax Planning
Corvee Tax Planning is designed for firms that want to productize tax advisory services and identify savings strategies at scale. It is often used by accounting firms working with business owners, high-income individuals, and clients with multiple entities. The platform focuses on strategy discovery, client-facing reports, and workflow support for advisory engagements.
Its strength is the ability to organize tax-saving opportunities into structured recommendations, such as entity selection, retirement planning, income shifting, and deductions. For firms that want to charge separately for tax planning packages, Corvee can support a more formal advisory process. It is best suited for firms ready to standardize planning conversations and invest in a higher-value service model.
2. Holistiplan
Holistiplan is widely used by financial advisors, wealth managers, and planning-focused professionals who want to review tax returns quickly. The software reads uploaded tax returns and generates summaries, observations, and planning opportunities. Instead of replacing tax preparation software, it helps advisors understand a client’s tax picture without manually reviewing every line of a return.
Holistiplan is especially useful for retirement distribution planning, charitable giving analysis, Roth conversion conversations, and capital gains management. Advisors can use it to collaborate more effectively with a client’s CPA. For firms that do not prepare returns but still want to integrate tax-aware advice into financial planning, Holistiplan is a strong fit.
3. TaxPlanIQ
TaxPlanIQ is built for accounting firms that want repeatable tax planning workflows, calculators, proposal tools, and client deliverables. It helps professionals organize strategies, estimate savings, and generate reports that explain recommendations in a more accessible format. The platform is often positioned toward firms that want to grow an advisory practice without building every workflow from scratch.
One of its key advantages is its library of tax strategies and planning templates. This can make it easier for staff members to identify opportunities consistently, rather than relying only on senior-level expertise. TaxPlanIQ may be particularly useful for firms moving from hourly compliance work into fixed-fee advisory engagements.
4. Intuit ProConnect Tax Advisor
Intuit ProConnect Tax Advisor is a practical option for firms already working within the Intuit ecosystem. It is designed to help professionals estimate tax outcomes, compare scenarios, and deliver planning insights to individual and business clients. Firms using ProConnect Tax, Lacerte, or related Intuit products may find the workflow familiar.
The platform is a good choice for smaller and mid-sized firms that want planning tools connected to tax preparation activity. It can support year-end projections, estimated tax reviews, and advisory conversations around deductions, income timing, and entity decisions. Its value is strongest when the firm already uses Intuit products and wants less friction between compliance and planning.
5. Thomson Reuters Planner CS
Planner CS, commonly associated with Thomson Reuters tax and accounting solutions, is a robust planning tool for firms that need detailed tax projections and multi-year analysis. It is often considered by firms that already use UltraTax CS or other Thomson Reuters products, since integration and data flow can be important advantages.
Planner CS can help firms model federal and state tax outcomes, compare alternatives, and prepare client-facing planning reports. It is suitable for more technical tax departments that handle complex individuals, business owners, estates, or multistate situations. While it may require more training than lighter advisory tools, it offers depth for firms that prioritize accuracy and detailed modeling.
6. CCH Axcess and CCH ProSystem fx Planning
CCH Axcess and related CCH ProSystem fx Planning tools are typically used by larger CPA firms, enterprise practices, and firms with sophisticated tax departments. These solutions can support tax projections, compliance workflows, and firm-wide data management. For organizations already standardized on CCH products, planning capabilities can fit naturally into existing processes.
The main advantage is the ability to operate within a professional-grade tax ecosystem. Firms serving high-net-worth clients, partnerships, corporations, and complex multi-entity groups may benefit from the depth and scalability of CCH solutions. However, these platforms may be more than a small advisory-only firm needs, especially if the goal is simply to create simplified planning summaries.
7. Drake Tax Planner
Drake Tax Planner is often attractive to small and mid-sized tax practices that want affordable planning functionality alongside tax preparation. Drake is known for practical tools, straightforward workflows, and value-conscious pricing. Its planning features can help firms run projections, compare tax years, estimate liabilities, and discuss upcoming obligations with clients.
Drake may not offer the same advisory packaging or advanced strategy libraries as some specialized platforms, but it can be highly useful for firms focused on efficient compliance plus basic planning. It is a sensible option for practices that want to add forecasting and tax estimate conversations without adopting a larger advisory software stack.
How Firms Should Compare Tax Planning Platforms
When evaluating tax planning software, firms should consider more than feature lists. The most important question is how the platform will support the firm’s service model. A CPA firm selling annual tax planning engagements may need strategy libraries, proposal tools, and client reports. A wealth management firm may need fast tax return analysis and planning observations. A high-volume tax office may need simple projections built into existing preparation software.
- Client type: Business owners, retirees, high-net-worth individuals, and W-2 households require different planning depth.
- Integrations: Software connected to existing tax preparation or financial planning tools can reduce duplicate data entry.
- Reporting: Clear, branded, client-friendly reports can make advisory recommendations easier to understand.
- Workflow: Task management, templates, and repeatable processes help firms scale planning services.
- Pricing: Firms should compare software costs against expected advisory revenue and staff efficiency gains.
The right platform should help professionals deliver advice earlier, not just calculate taxes after the year is over. In many cases, the best choice is not the most complex system, but the one the firm will actually use consistently across client relationships.
