Compare 10 transfer pricing firms for 2027, from Big Four practices to economic consultancies and boutiques, covering documentation, APAs and audit defense.
Any business that buys, sells, lends or licenses between related companies in different countries has to price those transactions at arm’s length and prove it. Tax authorities have stepped up reviews of intercompany pricing, documentation rules keep expanding, and the OECD’s global minimum tax framework has added new data demands. That is why many multinationals, and a growing number of mid-sized companies, hire outside transfer pricing firms.
This list covers transfer pricing consultants and firms that provide transfer pricing planning, documentation, benchmarking, advance pricing agreements and audit defense. We included Big Four practices, a global law firm, economic consulting firms and several smaller specialists, because the right choice depends heavily on company size and the type of problem. Each firm was checked against its own website, and we only describe services the firms list themselves.
Transfer pricing often overlaps with other cross-border and credit planning. If you are also reviewing research credits, see our sibling list of R&D tax credit consultants.

Best Transfer Pricing Firms In 2027
1. Deloitte — Big Four Practice With Dedicated APA And MAP Teams
Deloitte offers transfer pricing within its direct tax practice and frames its approach around aligning intercompany pricing with how a company actually operates and creates value. Its U.S. offering is split into four parts: transfer pricing advisory, APA/MAP/controversy, transfer pricing documentation and transfer pricing technology services.
The separate controversy line matters for companies already under examination or expecting double taxation, because advance pricing agreements and mutual agreement procedures are slow, specialized processes. The technology services help large groups automate intercompany calculations and documentation across many entities.
Deloitte is best suited to large multinationals with operations in many countries and the budget for a Big Four engagement.
Best for: Large multinationals that need global coverage and dispute resolution.
2. PwC — Global Coordinated Documentation And Value Chain Work
PwC’s U.S. transfer pricing practice covers six areas: reporting, global structuring, value chain transformation, operational transfer pricing, value chain analysis, and controversy and dispute resolution. Its Global Coordinated Documentation framework is designed to keep master files and local files consistent across countries.
PwC says its controversy team includes former Treasury and IRS officials and that it uses MAP and APA processes to reduce risk. It also uses AI-enabled platforms to centralize data and automate analytics, and it advises clients preparing for the OECD’s two-pillar reforms.
The firm fits multinationals that want documentation, operating model changes and dispute support handled by one global team.
Best for: Multinationals that need coordinated documentation across many jurisdictions.
3. DLA Piper — Law Firm Transfer Pricing Team With Lawyers, Accountants And Economists
DLA Piper’s transfer pricing and valuation practice plans, documents and defends cross-border transactions. The team combines lawyers, accountants and economists, including former government tax officials and technical advisers to the World Bank, OECD and IBFD. It works with the firm’s tax controversy group on audit strategy, MAP requests and advance pricing agreements, and its examples include bilateral APAs involving the U.S., U.K., France and Switzerland.
The practice also handles valuations for tax and financial reporting, such as intangibles and cost sharing arrangements. It reports Band 1 in Chambers Global 2025 and Tier 1 in The Legal 500 US 2025 for international tax.
A law firm team is useful when a transfer pricing dispute could reach litigation and the company wants work done under legal privilege.
Best for: Companies facing high-stakes disputes or complex intangibles and restructuring.
4. NERA — Economic Consulting Firm With A Large In-House Economist Team
NERA is an economic consulting firm working since 1961, with more than 500 professionals worldwide. It is a subsidiary of Marsh. NERA describes its transfer pricing practice as having one of the largest in-house teams of economists in the economic consulting world.
The practice offers full transfer pricing services, independent advice and valuation support, and it works with multinationals, their tax advisors and law firms on litigation and arbitration. Its transfer pricing professionals are listed in Chicago, New York, White Plains, Los Angeles, London, Paris, Frankfurt, Brussels and Tokyo.
NERA is a strong fit when a transfer pricing question turns on hard economics, such as valuing unique intangibles or defending a method in front of a court or arbitrator.
Best for: Companies needing rigorous economic analysis or expert support in disputes.
Charles River Associates (CRA) is a Boston-headquartered economic and management consulting firm that has advised clients since 1965. Its transfer pricing practice supports the full tax cycle: planning, documentation and tax valuation, plus audit defense, litigation and alternative dispute resolution support, and expert testimony.
The firm has been adding senior talent. In 2025 it hired Arin Mitra, a former Big Four principal who has led the economic analysis for more than 50 bilateral APAs involving the U.S., Japan, Australia, India, Canada and France. It also leads a Canadian transfer pricing practice from Toronto.
CRA suits companies that expect a contested examination and want economists who can testify.
Best for: Companies preparing for contested audits, APAs or litigation.
6. BDO USA — Middle-Market Transfer Pricing And Operational Support
BDO USA is the U.S. member of BDO International and part of the global BDO network. Its international tax and transfer pricing practice, led by managing principal Barb Derus, helps companies review and refine transfer pricing policies, methods and documentation as international rules change.
BDO also offers operational transfer pricing, which focuses on actually carrying out intercompany policies in accounting and ERP systems so that year-end results land within the target range. That practical side is often where mid-sized companies struggle.
BDO is a good fit for middle-market multinationals that want a national firm with international reach but not a Big Four fee structure.
Best for: Middle-market companies that need policies implemented, not just documented.
7. Baker Tilly — Full Documentation, Benchmarking And Audit Support
Baker Tilly’s transfer pricing team reviews and revises master files, local files and intercompany agreements, prepares benchmark studies to set intra-group prices, and compiles compliance filings including country-by-country reporting.
The team also advises on transfer pricing policies, intangibles valuation, supply chain structures, permanent establishment risk, secondments and intra-group financing, and it supports clients through transfer pricing audits. It publishes guidance on topics such as year-end adjustments, Pillar Two data readiness and the services cost method.
Baker Tilly fits mid-sized groups that want transfer pricing alongside audit, tax and advisory services from one national firm. It also supports business restructurings and the design of transfer pricing systems, which helps when a group is reorganizing its supply chain.
Best for: Mid-sized groups needing master file, local file and CbCR support.

The team is led by Alex Martin, an economist with 25 years in the field. KBKG says International Tax Review named its practice one of the world’s leading transfer pricing practices for the fourth consecutive year in 2024. The firm publishes example results, such as a case where cutting inventory transfer prices by $3 million produced $330,000 in annual tax savings.
KBKG is well suited to growing companies and to CPA firms that want a specialist partner for transfer pricing work.
Best for: Growing companies and CPA firms that need a specialist transfer pricing partner.
9. Bennett Thrasher — Mid-Sized CPA Firm With Transfer Pricing Through APA Negotiation

Its transfer pricing practice, led by Ben Miller, covers planning, documentation and compliance, controversy management and advance pricing agreement negotiation, and serves as a center of excellence within the DFK International and LEA Global networks.
Client testimonials on the firm’s site describe support during German transfer pricing audits, including one where the review ended after the authorities examined the client’s local file.
The firm is a practical choice for mid-sized U.S. companies with foreign affiliates, especially in Europe, that want partner-level attention.

How To Choose A Transfer Pricing Firm
What Problem Are You Solving?
Annual documentation, a new structure, an open audit and an APA application call for different skills. Documentation and benchmarking are widely available, while audit defense and APAs need people who have negotiated with tax authorities many times.
Do You Need Legal Privilege?
If a dispute could reach court, consider a law firm team or an economic consultancy hired through counsel. Ask your advisors how privilege will be handled.
How Many Countries Are Involved?
Groups in a few countries can work well with a mid-sized firm. Groups in dozens of countries usually need a global network or a technology platform that keeps local files consistent.
Who Will Do The Economic Analysis?
Ask who prepares the functional analysis and benchmarking, what databases they use, and whether senior economists review the results.
How Does It Fit Your Wider Tax Plan?
Transfer pricing interacts with credits, financing and real estate decisions. Companies with large property holdings should coordinate with their tax strategy advisors.
Frequently Asked Questions
What Is Transfer Pricing Documentation?
It is the analysis and reports that show intercompany prices meet the arm’s length standard. Under the OECD approach this typically includes a master file, local files and, for large groups, country-by-country reporting.
What Is An Advance Pricing Agreement?
An advance pricing agreement is an agreement with one or more tax authorities on the method used to price certain intercompany transactions for future years. Bilateral APAs involve two countries and help prevent double taxation.
Do Small Companies Need Transfer Pricing Firms?
Any company with related-party transactions across borders is subject to transfer pricing rules. Smaller groups often use a specialist or mid-sized firm to keep costs proportionate.
Conclusion
Large multinationals usually start with Deloitte, PwC or DLA Piper, while companies facing a contested case often add an economic consultancy such as NERA or Charles River Associates. Middle-market groups have strong options in BDO USA, Baker Tilly, KBKG, Bennett Thrasher and TPA Global. Match the firm to the problem, confirm who will do the work, and keep your transfer pricing positions consistent with the rest of your tax plan.
