KPMG

KPMG is one of the largest professional services networks in the world, offering audit, tax, and advisory services across more than 140 countries. For family offices and private wealth clients, the relevant offering sits within its advisory practice, which covers areas including tax structuring, risk and regulatory compliance, ESG, M&A advisory, and value creation for private equity and investment portfolios. Their website does not surface a dedicated family office or private wealth product, but KPMG’s UK practice explicitly covers professional services that family offices and their advisors commonly engage on a project or ongoing retainer basis.

Family offices typically engage KPMG for work that requires institutional-grade depth and cross-border reach, particularly where internal teams lack specialist capacity:

• Tax structuring and compliance across multiple jurisdictions
• Audit and financial reporting for complex entity structures
• Risk and regulatory advisory as compliance requirements evolve
• ESG and sustainability reporting and strategy
• M&A and carve-out advisory for investment portfolios

The trade-off a family office accepts by engaging KPMG is one common to the Big Four: depth of expertise and global coverage come at a cost structure suited to larger engagements, and the relationship model typically routes through senior partners while delivery involves larger teams. Pricing is not publicly disclosed and is engagement-specific. Family offices seeking a smaller, more dedicated advisory relationship may find boutique alternatives a better operational fit, but for cross-border tax, audit, and transactional work at scale, KPMG’s network coverage is difficult to replicate with a single-country firm.
