Andersen Group Expands Into Nigeria as Tax Reforms and AfCFTA Drive Advisory Demand
The Andersen Group Nigeria acquisitions form part of a wider global expansion, as the the firm looks to capture demand from new tax reforms and AfCFTA trade flows in a fast-growing consulting market.
Andersen Group Inc., a U.S.-headquartered provider of independent tax, valuation and financial advisory services, has acquired a tax firm and a consulting firm in Nigeria as part of a wider $34.5 annualized revenue expansion, amid new tax reforms and rising demand for cross‑border advisory under the African Continental Free Trade Area.
The NYSE‑listed professional services firm announced May 6, 2026 that it also closed deals for tax firms in Ireland and New Zealand and a tax and law firm in Uruguay. A Canadian acquisition is expected to close in the third quarter.
While Ireland and New Zealand were described as “strategically important developed markets,” Andersen called Africa a “significant long‑term growth opportunity,” citing both the continent’s potential and its growing role in the firm’s global strategy.
Nigeria’s new unified tax code, effective January 2026 after enactment in June 2025, repeals dozens of fragmented laws and replaces the Federal Inland Revenue Service with the Nigeria Revenue Service.
Key changes include VAT exemptions on food, healthcare and education; a ₦800,000 individual tax‑free threshold; and small business exemptions up to ₦50–100 million turnover. Corporate tax is set at 25%, while capital gains tax rises to 30% for companies.
Andersen didn’t disclose the identities of the Nigerian acquisitions, but noted: “The integrations are part of Andersen Group’s broader M&A strategy to incorporate select member and collaborating firms from across the Andersen Global platform into the public company.”
Upon completion, Anderson said “the firms will operate under the Andersen brand, aligning with the organization’s global standards, culture, and client service model.”
The move builds on nearly a decade of groundwork in Nigeria.
In 2017, Andersen Global entered the market through a partnership with WTS Adebiyi & Associates, later rebranded as Adebiyi Tax & Legal with offices in Lagos and Abuja. At the time, Andersen CEO and co-founder Mark Vorsatz described Nigeria as the firm’s “first entry into the region” and a cornerstone of its Africa strategy.
Two years later, it signed a collaboration agreement with Lagos‑based law firm The New Practice (TNP), strengthening its platform in Nigeria and deepening ties between its tax and legal teams. Vorsatz described TNP as “another strategic group that is relevant to our strategy in Africa and rounds out our platform in Nigeria.”
Taiwo Oyedele, now Minister of Finance and Coordinating Minister of the Economy after a May 2026 cabinet reshuffle, is overseeing implementation of the reforms he helped design as Chairman of the Presidential Committee on Fiscal Policy and Tax Reforms from 2023.
On assumption, he itemized ”revenue optimization and fair taxation” as part of the country’s strategic priorities. Those priorities are now shaping the tax regime multinationals and SMEs must navigate, creating advisory gaps Andersen aims to fill.
The Anderson Group Nigeria acquisitions also position the firm ahead of trade flows under AfCFTA, which Nigeria ratified in 2020 and began trading under in 2024.
As tariffs fall across 54 African markets, companies are expected to restructure supply chains to manufacture in Nigeria and distribute across West Africa, amplifying cross‑border needs such as permanent establishment risks and double taxation treaty planning.
The broader Nigeria management consulting market is projected to reach $2.03 billion by 2031, according to Mordor Intelligence, with tax and regulatory advisory among the fastest-growing segments as businesses navigate compliance requirements under the 2025 Tax Act and AfCFTA.
SMEs are driving much of that growth at a 5.05 percent CAGR as tax reforms and digital platforms make advisory services more accessible.
“These transactions reflect the disciplined execution of our strategy to build a truly global, multidimensional professional services platform within the public company,” said Mark Vorsatz, global chairman and CEO of Andersen, in the statement announcing the acquisitions.
“Our recent transactions underscore the depth of our pipeline and the pace at which we are expanding the platform.”
If Nigeria’s reforms hold and AfCFTA trade volumes continue to pick up, demand for tax advisory, M&A structuring and compliance services is expected to grow in the coming years.
