We recommend keeping them for at least 10 years. While the standard Thai statute of limitations is 5 years, this can be extended to 10 years in serious cases. Keeping your records for the full 10 years is the safest approach.

No. We can only provide advice or verify amounts if we’ve seen the documentation. If you’re unsure, upload your documents and message us — we’re happy to help once we’ve reviewed them.

Use the client portal — each income or deduction section has a place to upload directly.

We’ll still file your return using the required information you provided in your organiser. If you do not provide the recommended supporting documents, we won’t be able to confirm accuracy or provide advice. If audited later, you’ll need to supply proof yourself.

If you wish to claim a foreign tax credit, we recommend you provide proof of tax paid (e.g., tax certificate, summary, or return). So we can help you calculate and submit any tax credits.

For our portal, yes that is Ok. You need to keep the original documents/sources in case the Revenue Department requests them.

No. We upload digital copies. You only need originals if the Revenue Department asks you to attend in person.

No. We only submit the required filing data and any required certificates (e.g., TAWI50 for interest). Other supporting documents are stored securely in your portal and only submitted if there is an audit or specific request.

Thai or English is fine. If documents are in another language, we recommend translating to English. We offer a translation service — just ask for a quote.

You don’t have to upload every bank statement. We just require the total amount remitted to Thailand in THB for each income source. But if you want us to check your calculation or support it in case of audit, it helps to upload clear records of amounts transferred and from which income source.
