P.N.D. 51 Breakdown: The Mid-Year Corporate Tax Filing
In Thailand, Corporate Income Tax (CIT) isn't just paid once a year. The system uses a Mid-Year Estimative Return called the P.N.D. 51. This filing is the bridge between your first half performance and your full year projection.
The Deadline
- Paper Filing: Within 2 months from the end of the first 6 months of the accounting period (usually by August 31st).
- Electronic Filing: The Revenue Department usually grants an extra 8 days (early September).
- Our Advice: Do not wait until August. Perform your audit in June so you have two months to resolve any discrepancies.
What is Filed?
You are not filing your final audited profit. You are filing an Estimate of your net profit for the entire year, divided by two. You then pay tax on that 50% estimate.
Why It Exists
The P.N.D. 51 allows the government to collect revenue throughout the year rather than waiting for a single lump sum. For you, it acts as a "Forced Audit"—ensuring that your accounting team is actually keeping the books up to date by the six-month mark.
