What Tang & Co does

Tang & Co is a privately held, family-operated chartered accountancy practice headquartered in Edinburgh, Scotland, with a secondary office in Glasgow. Founded in 1996 by Mark Tang after he qualified as an ICAS Chartered Accountant and gained international experience with a Big Four firm in Malaysia, the firm joined by his sister Charlotte Tang in 2005, who brought catering-sector expertise and multilingual capabilities. The firm operates as Tang & Co Limited, a private limited company governed by Scots law, with ICAS membership, RSA-provided professional indemnity insurance, and a team of 1-10 employees. It targets owner-managed small and medium businesses, sole traders, individuals with investment or rental income, British National Overseas (BNO) visa holders from Hong Kong and ASEAN countries, and a specialty cluster of ethnic-background hospitality and food businesses served through Charlotte Tang's multilingual practice.

The firm's core service portfolio comprises Accounting Services & Payroll, Tax Compliance, Business Advisory, Self-Assessment Returns, Company Secretarial, and a specialized BNO service line covering UK property purchase, foreign income reporting, tax residence and domicile, inheritance tax, and capital gains tax. Underlying technology is third-party cloud accounting software (used for bookkeeping and Making Tax Digital compliance); the firm has no disclosed proprietary platform, no app, and no API surface. Client engagement is conducted through direct partner involvement and digital channels including phone, email, WhatsApp, WeChat, and a full Chinese-language website section.

Tang & Co generates revenue on a professional services model with time-based fees calculated on time spent, skill and responsibility levels, importance and value of advice, and risk, supplemented by fixed fees for specific service packages and monthly or quarterly instalment payment options. Disbursements for travel and accommodation may be charged. The go-to-market is sales-led and overwhelmingly referral-driven, with the firm stating that over 98% of new clients come from personal recommendations. There is no external investment, no parent company, and no disclosed revenue, funding, or M&A activity.

Regional players

• Geoghegans: Glasgow-based chartered accountants offering accounting, tax, audit, and business advisory to SMEs, families, and individuals in the West of Scotland. Comparable to Tang & Co through shared Scottish SMB-focused service portfolio and partner-led delivery model.
• French Duncan: Scottish chartered accountancy firm headquartered in Glasgow offering accounting, tax, and advisory services to owner-managed businesses and SMEs across Scotland — directly comparable to Tang & Co in geography, client segment, and service mix, though without the BNO/Chinese-language niche.
• Campbell Dallas: Scottish chartered accountancy firm with offices across central Scotland providing accounting, tax, and advisory services to SMEs, family businesses, and individuals — directly comparable on size tier, geography, and service lines.
• Chiene + Tait: Edinburgh-based chartered accountancy firm serving individuals, SMEs, and not-for-profits across Scotland with accounting, tax, and advisory services. Comparable to Tang & Co by city, client size tier, and professional services positioning.

Broad incumbents

• MHA MacIntyre Hudson: UK Top-20 chartered accountancy network offering accounting, audit, tax, and advisory to SMEs and mid-market clients. Broad incumbent with comparable SMB accounting offerings, competing for owner-managed businesses across the UK.
• Mazars UK: Top-10 UK accounting, tax, and advisory firm serving mid-market and large clients. Broad incumbent that competes indirectly for SMB and owner-managed clients that might otherwise engage a small firm like Tang & Co.
• BDO UK: Major UK accounting and advisory network providing audit, tax, and consulting to mid-market and large businesses. A broad incumbent competitor rather than a direct SMB specialist — relevant as a ceiling on pricing and service-breadth expectations.
• Crowe UK: Top-10 UK accounting and advisory firm serving SMEs, owner-managed businesses, and larger corporates. Broad incumbent competitor in the same accounting/tax/advisory space, with substantially greater resources than Tang & Co.

Direct peers

• HW Fisher: London-based chartered accountancy firm serving SMEs, owner-managed businesses, and individuals with accounting, tax, and advisory services. Comparable to Tang & Co on client segment and service mix, though UK-wide rather than Scotland-focused.
• Kreston Reeves: UK Top-30 chartered accountancy firm serving SMEs, charities, and private clients with accounting, tax, payroll, and advisory across the South East. Comparable to Tang & Co on SMB-focused professional services positioning, though significantly larger in scale.
