Basics
The month-end checklist
Thirty minutes at the end of each month makes next month's filings and your accountant's work much easier. Just follow this order.
In short
Sort each month within the month and there is no year-end hunt for papers. It matters even more because withholding, social security and VAT filings all fall early the next month.
- Papers: upload every receipt and tax invoice of the month and fix what the checklist flags.
- Money: match the bank lines with the books and check money to come in and bills to pay.
- Tax and pay: check payroll, social security and withholding (50 ทวิ), look at the VAT figures, then close the month and send it to your accountant.
For example
What falls early next month
Withholding returns (ภ.ง.ด.1 · 3 · 53): by the 7th, e-filing by the 15th Social security (สปส.1-10): by the 15th VAT (ภ.พ.30): by the 15th, e-filing usually a few days later
Common mistakes
- Keeping receipts in a box and sorting them all at year end.
- Not matching the bank, so a missing sale or a cost entered twice goes unnoticed.
- Changing a month already filed, so the return and the books no longer agree.
