Thailand’s Revenue Code requires certain financial institutions and electronic-money providers to report information about people whose deposit or incoming-transfer activity meets specified thresholds. The report is information for the Revenue Department to use with other records. It is not, by itself, a tax assessment or proof that every transfer is taxable income.
What activity meets the statutory threshold?
Section 3/17 of the Revenue Code defines two tests for activity during the previous year:
- Deposits or incoming transfers across accounts reach at least 3,000 transactions; or
- Deposits or incoming transfers reach at least 400 transactions and the total amount is at least THB 2 million.
These are reporting thresholds. They do not tell you whether a specific payment is taxable, and they do not replace the rules for calculating income, deductions or tax due. The Revenue Department says reported information may be considered together with other information.
Reporting, review and filing are different
Reporting is the financial provider’s duty when the statutory test is met. Review means the Revenue Department may consider the report alongside other information. Filing is the taxpayer’s separate duty under the rules that apply to their income and circumstances.
Not meeting a reporting threshold does not decide whether someone must file a tax return. Likewise, reaching a reporting threshold does not automatically mean tax is owed. Keep records that explain business receipts, transfers between your own accounts, refunds, loans and other transactions.
Practical steps
- Keep statements and documents that explain the reason for significant receipts.
- Separate business and personal transactions where practical.
- Reconcile sales, invoices, refunds and bookkeeping records.
- Use the Revenue Department’s current filing guidance for your income type, or ask a qualified tax professional if the treatment is unclear.
