# P.N.D.50 Annual Corporate Income Tax Return

Country: Thailand
When: Within 150 days from the last day of the accounting period (Section 68 of the Revenue Code). For a 31 December year-end: 30 May, or 29 May in a leap year. Filing online through e-Filing gives 8 more days.

The annual corporate income tax return for Thai companies and juristic partnerships, filed and paid within 150 days of the year-end.

## Who this applies to

- Company limited and public company limited
- Limited partnerships and registered ordinary partnerships
- Branches of foreign companies

## What to file

Form P.N.D.50 with the audited financial statements, showing net profit and CIT at 20% (or the SME rates of 0% and 15% on the first 3 million baht where both conditions are met).

## How to file

On paper at a Revenue Department office or online through the Revenue Department's e-Filing system. AccountsOS does not submit to the Revenue Department. You or your accountant file.

## Payment due

With the return. Tax paid with P.N.D.51 is credited against it.

## What happens if you miss it

Unpaid tax carries a surcharge of 1.5% per month, and part of a month counts as a month. A fine can also apply; confirm the amount with the Revenue Department or your accountant.

## Submission checklist

- Close the books and have the statements audited
- Check both SME conditions before using the SME rates
- Add back entertainment above the 0.3% cap
- Credit the P.N.D.51 tax and any tax withheld from your income
- File and keep the receipt

## Documents you need

- Audited financial statements
- Tax computation from accounting profit to net profit
- P.N.D.51 receipt and 50 Tawi certificates received

## Common mistakes to avoid

- Using the SME rates when paid-up capital is over 5 million baht
- Missing the 150-day date because the year-end is not 31 December
- Treating a Finn estimate as a filed return
