Petroleum Securities (PSI) Fined VND 407.4M for Tax Under-Declaration

Overview

The Hanoi Tax Department has fined and back-assessed CTCP Chứng khoán Dầu khí (Petroleum Securities, ticker PSI) a combined VND 407.4 million for under-declared value-added tax, corporate income tax and personal income tax, according to the company’s disclosure of Decision No. 17550 dated 30 October 2026.

What Happened

In a company disclosure, PSI said the Hanoi Tax Department issued Decision No. 17550 on 30 October 2026 imposing an administrative penalty for incorrect tax declarations that resulted in shortfalls in VAT, corporate income tax and personal income tax. The fine itself is VND 57.7 million. As a remedial measure, the company must pay back taxes of VND 278.8 million, split between VND 10.4 million of VAT, VND 161.3 million of corporate income tax and VND 107.1 million of personal income tax, plus VND 70.8 million in late-payment interest. The combined obligation is VND 407.4 million.

The same disclosure announced the dismissal of deputy director Lưu Thị Việt Hà effective 30 October 2026, following her resignation request citing a change in work direction. On operations, PSI reported Q3/2026 total revenue of more than VND 103 billion, down 23% from the same period in 2025, with declines concentrated in gains on FVTPL financial assets, held-to-maturity investment income, brokerage and custody revenue, and other operating income. Total costs fell only 18% to roughly VND 90 billion, leaving pre-tax accounting profit at VND 13.5 billion, down 45%. For the nine months, revenue reached VND 339 billion (-6.8%) and pre-tax profit VND 65 billion (+38%).

Market Context

PSI trades on the HNX and closed at VND 7,500 on 31 October 2026, placing it among the lower-priced small-cap brokerage names. The tax decision and the quarterly profit decline arrive as Vietnamese securities firms face a mixed 2026: market liquidity has supported nine-month earnings at many brokers, but smaller houses with concentrated proprietary books and margin-lending exposure are seeing sharper swings in FVTPL and interest income. PSI’s nine-month profit growth of 38% contrasts with the Q3 contraction, suggesting the third quarter carried a heavier mark-to-market or cost burden than earlier periods.

Strategic Significance

The direct financial impact of VND 407.4 million is immaterial against PSI’s VND 65 billion nine-month pre-tax profit, so the investment relevance lies in governance rather than the balance sheet. A tax authority finding of under-declared personal income tax, in particular, points to payroll and withholding controls at a small broker, and the simultaneous departure of a deputy director adds to the impression of internal churn. For long-term holders, the key question is whether PSI can stabilise revenue mix away from volatile FVTPL and HTM gains toward recurring brokerage and custody income; the Q3 decline across exactly those lines suggests the recurring base is not yet offsetting proprietary swings.

What to Watch

• PSI’s Q4/2026 and full-year 2026 results, to see whether the Q3 margin compression reverses.
• Any further tax authority notices or adjustments to the company’s tax filings.
• Disclosure on a replacement for deputy director Lưu Thị Việt Hà and any broader management changes.
• HNX trading liquidity and price action around the VND 7,500 level following the disclosure.
• Sector-wide Q3 brokerage results, to separate PSI-specific issues from market-wide trends.
