Businesses evaluating enterprise-scale R&D tax credit services may encounter Deloitte, one of the Big 4 accounting firms. This page provides an independent comparison of Deloitte’s publicly described model and the year-round internal documentation approach represented by R&D Ledger. For a broader framework, see our page on how to choose an R&D tax credit provider.
What Deloitte Publicly Offers
According to Deloitte’s current website, Deloitte offers R&D tax credit services that combine technology (including AI) with deep tax experience. The website describes an AI-powered platform that cuts R&D process timelines while maintaining quality and compliance.
Deloitte’s website describes the Intela platform and a Tech Writer tool that provide full transparency into engagement status. The website describes efficient, well-supported documentation leveraging available data (including prior-year records), real-time visibility, and quality outcomes through technical rigor and structured documentation.
Provider and Engagement Model
Deloitte describes itself as a Big 4 professional services firm offering managed tax engagements. According to its website, the model involves a large-scale professional-service engagement with AI-powered technology support. The engagement is suited to enterprise teams that need a managed R&D credit service.
This is a large managed tax engagement model: Deloitte’s professionals conduct the R&D credit analysis using proprietary technology, and the engagement is integrated with the firm’s broader tax services.
How the Process Appears to Work
According to Deloitte’s website, the process involves using an AI-powered platform to prepare and organize documentation, leveraging available data including prior-year records, and providing real-time visibility into engagement status through the Intela platform and Tech Writer tool.
Documentation Approach
Deloitte’s documentation approach, as described on its website, involves leveraging available data to prepare and organize clear, well-documented support, maintaining audit-ready documentation, and using the Tech Writer tool for documentation generation.
Role of Software
Software is part of Deloitte’s model. According to its website, Deloitte uses an AI-powered platform (Intela) and a Tech Writer tool. The technology supports the managed engagement rather than being a standalone client-facing product.
Role of Human Professionals
Human professionals are central to Deloitte’s model. As a Big 4 firm, Deloitte’s partners and professionals conduct the engagement, apply technical rigor, and provide structured documentation. The model is professional-service-driven with technology support.
Year-Round vs. Study Considerations
Deloitte describes a managed tax engagement with a defined process and timeline. This is oriented toward a managed engagement rather than continuous year-round documentation by the internal team. Year-round internal documentation, as represented by R&D Ledger, involves the business’s own team organizing project, technical, cost, and evidence records throughout the year for professional review. For more on this distinction, see our page on year-round R&D documentation vs. annual study.
What a Buyer Should Compare
A buyer evaluating Deloitte against year-round internal documentation software may consider:
- Big 4 managed engagement vs. internal documentation: Deloitte provides a large managed tax engagement. Does the buyer want a Big 4 firm to manage the R&D credit process, or does it want to organize records internally?
- Enterprise scale: Deloitte’s model is suited to large enterprises. Is the buyer at that scale?
- AI-powered platform: Deloitte describes an AI-powered platform (Intela) and Tech Writer tool. Does the buyer value this technology?
- Broader tax services: Deloitte offers R&D credits as part of broader tax services. Does the buyer need integrated tax services?
- Engagement cost: Big 4 managed engagements may involve different cost structures. How does this align with the buyer’s budget?

When Deloitte’s Model May Make Sense
Deloitte’s model may make sense for a business that:
- is a large enterprise wanting a Big 4 firm to manage the R&D credit process;
- values AI-powered technology (Intela, Tech Writer) within a managed engagement;
- needs R&D credits integrated with broader tax services;
- has the budget for a Big 4 managed engagement; and
- wants real-time visibility into engagement status.
When Year-Round Internal R&D Tracking May Make Sense
Year-round internal R&D documentation may make sense for a business that:
- wants to organize project, technical, cost, and evidence records throughout the year internally;
- already has a CPA or tax team that handles filing and needs organized records to support that work;
- prefers to maintain its own documentation infrastructure rather than outsourcing to a managed engagement; and
- wants a documentation workspace that can support any CPA or consultant, including a Big 4 firm.

Can the Two Approaches Coexist?
A business could maintain year-round project and evidence records in a documentation workspace and also engage a Big 4 firm like Deloitte for the managed R&D credit engagement. The internal records could supply organized project, cost, and evidence data to support the firm’s AI-powered platform and analysis. The two approaches are not mutually exclusive: a business might use internal documentation for ongoing recordkeeping and a Big 4 firm for the managed engagement and broader tax services.
Questions to Ask Before Choosing
- Does the business want a Big 4 managed engagement, or does it want to organize records internally?
- Is the business at enterprise scale?
- How important is AI-powered technology within the managed engagement?
- Does the business need R&D credits integrated with broader tax services?
- How does the Big 4 engagement cost align with the business’s budget?
Key Takeaway
Deloitte is a Big 4 professional services firm that offers R&D tax credit services through a managed engagement model using an AI-powered platform (Intela) and Tech Writer tool, suited to large enterprise teams. Year-round internal R&D documentation, as represented by R&D Ledger, involves the business’s own team organizing project, technical, cost, and evidence records throughout the year for professional review. The two approaches differ in scale and who manages the process, and a buyer’s choice depends on its size and preference for managed engagement vs. internal documentation.
