6 ways to speed up your Thai tax refund
18 August 2025
Waiting on a tax refund can feel endless. Whether it’s Corporate Income Tax (CIT), Withholding Tax (WHT), Value-Added Tax (VAT), or even Stamp Duty (SD), the Thai Revenue Department reviews refund claims closely — and that slows things down. While audits are a normal part of the process, there are practical steps you can take to keep your refund moving faster.
Here are six tips to help you avoid delays and build trust with tax officers.
1. Know your business, taxes, and accounting inside out
If you want a faster tax refund, you need to understand your own numbers. Be ready to explain how your tax position was determined, how accounting policies apply, and what risks might exist.
When you can confidently answer questions from tax officers, you build trust and avoid delays. Preparation builds credibility.
2. Keep your documents organised and ready
Tax officers love well-prepared taxpayers. Before submitting your refund application, make sure all accounting and tax documents are complete, accurate, and easy to access.
Why? Because when tax officers request documents, you want to deliver them fast. Quick responses = quicker refunds.
3. Be friendly, polite, and professional
Yes, tax officers are humans too! How you interact with them matters more than you think.
Stay respectful, cooperative, and professional at all times. Good relationships can keep your file moving in the right direction.
4. Follow up – but nicely
Don’t just submit your refund request and cross your fingers. Take a proactive approach.
Follow up regularly with the Revenue Department. A polite reminder email shows you’re engaged and keeps your case on their radar.
And if they ask for more information, send it quickly. Even if you’re unsure, ask questions early — fixing small issues now avoids bigger delays later.
5. Be realistic about the outcome
Not every refund will be approved in full. That’s why it’s important to review your tax treatments upfront and be open to reasonable compromises.
If you know the treatment was incorrect, fighting every point only slows things down. Sometimes, accepting a fair resolution is the fastest way forward.
6. Work with a Tax professional
A good advisor can be a game-changer. From understanding technical rules to preparing documents or negotiating with the Revenue Department, a consultant can help you avoid common pitfalls and save time.
More than compliance, a tax professional can help you strategise, resolve disputes, and speed things up.
