Corporate Accounting & Tax Advisory (CATA)

Full-scope statutory bookkeeping, outsourced Chief Accountant services, tax structure review, VAT refund implementation, and supporting documentation for tax and audit review.

We keep the books, the tax position and the supporting evidence aligned, so that statutory filings, tax reviews and audits rest on records that can be traced.

Two-Tier Service Architecture

Tier 1: Retained Operational Accounting & Stewardship

  • Full-Scope Statutory Bookkeeping: Comprehensive daily accounting voucher processing, accounts payable/receivable, fixed asset registers, inventory costing, and month-end financial closings in full compliance with VAS and Circular 99/2025/TT-BTC.
  • Outsourced Chief Accountant Services: Appointing licensed Chief Accountants to take statutory responsibility, supervise transaction workflows, establish internal approval matrices, and formalize signatures on financial statements.
  • Cross-Functional Reconciliation with Customs (TASC Integration): Staffed with senior accountants cross-trained in customs regulations. Ensuring General Ledger accounts (152, 154, 155, 632) remain strictly reconciled with production scrap rates, physical inventory counts, and statutory customs finalization data.

Tier 2: Tax Structure Review & Specialized Case Solutions

When diagnostic reviews identify material historical exposures or complex liquidity opportunities, IPAS deploys specialist project teams under dedicated project scopes:

  • FDI Capital Expenditure & Export VAT Refunds: Structuring dossiers, reconciling payment trails, and defending high-value VAT refunds for newly established factories and export regimes.
  • Pre-Audit Tax Exposure Remediation: In-depth historical tax health-checks, non-deductible expense restructuring, and documentation review and remediation before statutory inspections.
  • Specialized Tax/Fee Diagnostics: Environmental protection tax/fee audits, CIT incentive compliance evaluations, and contract-specific tax structuring.
  • On-Site Tax Review Support & Technical Explanation: Preparing supporting documentation for audit or tax review and providing technical explanations before tax audit delegations under Law on Tax Administration 108/2025/QH15.
