Right Tax Service

What Right Tax Service does

Right Tax Service is a US-licensed professional tax services firm specializing in cross-border US tax compliance for Korean-speaking individuals, families, and businesses. Founded by Mark Kang (강주형) — a KAIST Physics PhD, former Stanford researcher, and US Certified Public Accountant (NY) — the firm addresses a documented service gap: Korean-Americans, Korean permanent residents, and US citizens residing in Korea who face complex obligations under Form 1040, FBAR, FATCA, Form 5471, Streamlined Procedures (SDOP/SFOP), and gift/estate tax rules. The company operates dual offices in Great Neck, NY (US headquarters) and Seoul's Gangnam district (Korean client consultations), with a proprietary SmartTax online portal (rightclientportal.com) that handles case intake interviews, document submission, fee estimation, and real-time status tracking.

The service portfolio spans personal tax filing, Streamlined Procedures penalty-forgiveness representation, cryptocurrency tax reporting, foreign asset compliance (FBAR/FATCA), foreign corporation reporting (Form 5471), US gift and estate tax (Forms 709/706), and corporate tax and accounting for Korean-owned US entities. Pricing is structured around professional service fees with a 50% deposit required to commence work; rates are not publicly disclosed and are determined per engagement after an intake interview. Distribution relies on direct sales via the website and Calendly, bilingual content marketing (YouTube @markkangtax, Naver Blog, Instagram), and a referral network anchored by Gookminiju (immigration), Saemubupin Hana (Korean tax firm), and Korini (US real estate platform).

Revenue is generated exclusively through professional service fees across individual compliance, advisory consultations, and corporate engagements. The firm has disclosed one $500,000 funding round (September 2021) with no subsequent raises, remains founder-owned and operated, and has no parent company or institutional investor on record. Customer outcomes scale into the thousands of cases, particularly within Streamlined Procedures representation, indicating meaningful but boutique-scale operating throughput.

Expansion highlights6 records

Broad incumbents

• Deloitte Tax (Korean Services Group): Big Four firm serving Korean multinational clients and Korean-American investors with cross-border tax planning. Significant overlap with Right Tax Service's pre-landing, EB-5, and cross-border advisory segments.
• EY (Korea Business Center): Big Four with a Korean Business Center providing tax and advisory services to Korean companies in the US. Competes for the same Korean-business-entering-US segment that Right Tax Service addresses through corporate consulting.
• KPMG US (Korean Practice / Korea Desk): Big Four firm with a dedicated Korean Business Practice serving Korean companies in the US and Korean-American HNW clients. Directly competes for higher-end Korean-diaspora tax and advisory work that Right Tax Service targets via partnerships.
• Liberty Tax Service: US and Canadian tax preparation franchise chain with neighborhood offices, similar to Jackson Hewitt. Overlaps with Right Tax Service at the entry-level individual 1040 segment but does not focus on cross-border or Korean-diaspora scenarios.
• BDO USA: Top-10 US accounting firm with growing Korean-desk practice and cross-border capabilities. Provides similar personal and corporate tax services to Korean-American clients and Korean-owned businesses in the US.
• H&R Block: Large US tax preparation retailer with thousands of offices. Offers DIY software plus in-person preparation, but lacks the Korean-language specialization and cross-border FBAR/FATCA depth that Right Tax Service provides to Korean-Americans.
• Jackson Hewitt Tax Service: National US tax preparation chain focused on individual returns with significant Korean-American customer base in NY/NJ. Competes for the same Korean-speaking retail tax clients as Right Tax Service, though without the firm's cross-border specialization.

Direct peers

• GreenSky CPA / 한인 세무사 그룹: Korean-American CPA firm offering US tax preparation for Korean-speaking clients, including FBAR/FATCA and small business filings. Directly competes with Right Tax Service for the same Korean-American individual tax segment in the NY/NJ area.
• 1040Abroad: US tax preparation firm specializing in US expats and foreign account reporting (FBAR, FATCA). Direct peer to Right Tax Service in cross-border and Streamlined Procedures services, though without the Korean-language and Korean-office depth.

Emerging players

• TurboTax (Intuit): Mass-market DIY US tax software increasingly adding FBAR and cross-border support. Threatens Right Tax Service's entry-level 1040 filing fees, though the firm remains positioned for complex cases the software cannot handle.
