In late October 2026, newly released data from South Korea’s National Tax Service analyzed by Moon Jin-seok revealed that self-employed medical doctors reported an average annual business income of 402 million won for the 2024 tax year, ranking first among 14 professional categories.
In Plain English: The Clinical Takeaway
- Business Income vs. Salary: The figures reflect pre-tax earnings for self-employed practitioners after subtracting operating expenses, excluding salaried hospital physicians and corporate-employed medical staff.
- Comparative Scale: The reported medical business earnings outpace other licensed professions in the dataset, standing at roughly 3.8 times the average business income reported by lawyers during the same period.
Tax Data Details From the National Tax Service
The figures emerged from “Professional Sector Business Income Reporting Status” data submitted to the National Assembly’s Strategy and Finance Committee by Moon Jin-seok of the Democratic Party of Korea, fnnews.com reported. The statistics specifically capture individuals who filed taxes as sole proprietors, accounting for total revenue minus necessary operating expenses such as personnel costs and rent.
Salaried clinicians and those operating under corporate legal entities do not appear in these figures, as their earnings fall under employment income rather than business income. Dentists and traditional Korean medicine doctors are tracked under separate categories and were excluded from the primary physician cohort.
Among the 14 professional groups evaluated in the 2024 data, physicians claimed the highest average business income at 402 million won. Dentists followed at 222 million won, accountants at 122 million won, traditional Korean medicine doctors at 119 million won, and lawyers at 106 million won.
Lower tiers of the 2024 professional earnings list included tax accountants at 82 million won, patent attorneys at 80 million won, customs brokers at 60 million won, appraisers at 39 million won, judicial scriveners at 32 million won, architects at 30 million won, and labor attorneys at 25 million won.

Longitudinal Growth in Reporting Physicians and Total Revenue
The number of medical practitioners filing business income taxes expanded over a seven-year span. In 2017, 37,140 physicians submitted business income reports. By 2024, that count grew by 17.7% to reach 43,718 individuals.
Total aggregate business income reported across this demographic climbed even faster. In 2017, reporting physicians collectively declared 9,763,920,000,000 won. By 2024, the aggregate total reached 17,563,136,000,000 won, marking a 79.9% surge over the period.
Annual averages fluctuated across the timeline. Average business income stood at 263 million won in 2017, rising to 291 million won in 2018 and 323 million won in 2019. A temporary dip occurred in 2020 down to 300 million won, followed by a rebound to 354 million won in 2021 and 398 million won in 2022. After retreating to 378 million won in 2023, the average surpassed the 400 million won threshold in 2024.
Contraindications & When to Consult a Doctor
Patients experiencing acute medical symptoms, chronic disease manifestations, or medication side effects should seek immediate evaluation from a licensed healthcare provider rather than factoring economic reporting into medical decision-making.
Professional medical consultations should be prioritized whenever acute warning signs arise—such as unexplained severe pain, respiratory distress, neurological deficits, or hemodynamic instability—regardless of national statistical averages or professional earnings disclosures.
