- 01Can I stay on my existing accounting software (Xero / QuickBooks Online)?
- Yes. iVC operates in Xero, QuickBooks Online, PEAK, FlowAccount, Express and SAP B1. We do not force migration if your current setup already meets TFRS for NPAEs disclosure requirements.
- 02What happens if I miss a filing deadline before we onboard?
- We quantify the exposure in the first week: PND./PP.30 late-filing surcharge is typically THB 200–2,000 per return plus 1.5%/month interest on tax owed. We prepare a voluntary correction filing (Section 22) which usually halves the surcharge.
- 03How is the audit fee handled?
- Statutory audit must be performed by an independent CPA — we cannot audit our own books. Auditor fees typically run THB 25,000–120,000/year depending on revenue and complexity. iVC coordinates and prepares the audit file so the CPA can complete in weeks, not months.
- 04Do you handle payroll and Personal Income Tax withholding?
- Yes. Monthly PND. 1 filing and annual PND. 1 Kor (employee summary) are included. We also prepare each employee's PND. 91 personal tax return by end-March if requested.
