Jisung Tax Accounting office

What Jisung Tax Accounting office does

Jisung Tax Accounting Office (지성세무회계사무소) is a single-office Korean professional services firm headquartered in Sejong Special Self-Governing Province, South Korea, established in 2015 (per the website copyright notice). The firm delivers traditional tax and accounting services — bookkeeping (장부기장), corporate and individual income tax filing, VAT, statutory accounting audits, and consulting — alongside specialized practice areas covering inheritance tax, capital gains/transfer tax, and sector-specific engagements for restaurants and cafes, construction companies, medical institutions (including Sejong Hospital), and public interest corporations. The firm also provides startup support services such as business owner registration and corporate establishment, positioning it to serve new entity formation in Sejong, Korea's administrative capital.

The practice is led by founder-representative Kim Seon-pil (김선필), a dual-licensed CPA and Tax Attorney (공인회계사/세무사) holding a Master of Law in Tax Law from Yonsei University Graduate School and a bachelor's degree from Ajou University, credentialed since 2005. His prior experience includes roles at EY Han-young Accounting Corporation, Daeju Accounting Corporation, and as an Investigation Committee Member at Cheongju District Court, with disclosed past engagements covering SK Gas, Hana Bank, Samsung Total, IBK Industrial Bank, Hanwha Group, Kyobo Books, and Sejong Hospital, plus K-IFRS conversion projects and tax-dispute resolution work. The firm does not build or sell software products, does not maintain an app, has no API/SDK, and does not employ AI/ML technology.

Revenue is generated through professional service fees under a sales-led direct-engagement model; pricing is not publicly disclosed and prospective clients obtain quotes by contacting the office via phone (044-868-8430), email ([email protected]), or website contact form. Marketing is concentrated in content distributed via the firm's blog (jsstar.co.kr), which has accumulated 284,757+ visitors and supports an email newsletter subscription. The firm is privately held with no disclosed parent, investors, funding, partnerships, or third-party distribution arrangements. A metadata discrepancy exists: firmographics records "Russian Federation/Adygeya" as the country/city, but every primary-source signal — Korean-language legal name (지성세무회계사무소), registered Sejong address, Korean phone number, blog content, and ownership commentary — confirms the firm's domicile in Sejong Special Self-Governing Province, South Korea, which is the operative factual basis for this analysis.

Others

• 더존비즈온 (Douzone Bizon): Korea's leading accounting/ERP software vendor, whose iCUBE and Smart A products are widely used by SMBs and tax offices. Relevant as an ecosystem participant whose software increasingly enables SMB clients to handle routine filings in-house, structurally pressuring solo tax practices like Jisung.

Broad incumbents

• 대주회계법인 (Daeju Accounting Corporation / BDO Korea): Korean member firm of BDO and Jisung's founder's former employer. Directly comparable tax/audit/advisory offering, but with national reach and enterprise-scale mandates versus Jisung's single-office Sejong practice.
• EY한영회계법인 (EY Han Young): Korean member firm of Ernst & Young, one of the Big-4 in Korea. Directly relevant because the Jisung founder previously worked here, and EY Han Young provides the same tax filing, advisory, and audit services that Jisung offers — but at enterprise scale.
• 안진회계법인 (Anjin / Deloitte Korea): Korean member firm of Deloitte, providing tax, audit, and consulting services. Comparable to Jisung along the tax-and-accounting service axis, though operating at multi-thousand-employee scale with global corporate clients.
• 삼일회계법인 (Samil Accounting Corporation / PwC Korea): Largest Korean accounting firm and PwC Korea affiliate, offering tax, audit, and advisory services across all enterprise tiers. Comparable because it operates in the same Korean tax/accounting services category as Jisung, but at vastly larger scale and with national coverage.
• KPMG삼정회계법인 (Samjong KPMG): Korean member firm of KPMG, providing tax, audit, and advisory services to enterprise and mid-market clients. Overlaps with Jisung on tax compliance and advisory, though operating at substantially larger scale and with multinational clients.
