Simple Steps to File VAT Correctly


Check Your Sales Revenue

Businesses with annual sales revenue exceeding 1.8 million THB are required to register for VAT in accordance with Thai law. If your business exceeds this threshold, VAT registration becomes mandatory. Regularly checking your sales revenue ensures that you are aware of whether your business is subject to VAT obligations.


Register for VAT

VAT registration is a crucial step for businesses to obtain a VAT number. This number is necessary for issuing tax invoices and managing tax-related transactions. Registration can be completed through the Revenue Department by submitting the required information and following the prescribed application process.


Calculate VAT

VAT is calculated by subtracting input VAT (VAT paid on purchases) from output VAT (VAT collected on sales). This means that if you purchase goods and services with VAT from your suppliers, you can offset the VAT you’ve paid against the VAT you’ve collected from your customers. If your output VAT exceeds your input VAT, you will need to pay the difference to the Revenue Department.


Submit Form Por.Por.30 (PP.30)

Businesses that are registered for VAT must submit Form Por.Por.30, commonly referred to as PP.30, by the 15th of the following month after the end of the tax period. This form reports the VAT collected on sales and the VAT paid on purchases. Filing this form correctly and on time helps prevent tax errors and ensures compliance.


Pay VAT

If the calculation shows that your business owes VAT after offsetting input and output VAT, you are required to pay the tax to the Revenue Department. Payment can be made via bank transfer or through the online payment system provided by the Revenue Department. Timely and accurate payment ensures transparency and prevents legal issues.


Key Takeaway:

Properly filing VAT returns not only ensures your business remains transparent and compliant with the law but also helps avoid legal risks. Adhering to these processes will contribute to your business's credibility and long-term growth.

Consequences of Not Filing VAT

Failing to comply with VAT filing requirements can lead to significant legal and financial repercussions for your business. Here’s a detailed breakdown of the potential consequences:


Fines & Interest Charges

One of the immediate consequences of not filing VAT on time is the imposition of fines and interest charges. If you miss the filing deadline, you could face fines ranging from 1,000 to 2,000 THB. In addition to this, a 1.5% monthly interest charge will be added on the outstanding tax amount. These fines and interest can quickly accumulate, leading to a higher financial burden and complicating your business's cash flow.


Tax Audit Risks

Non-compliance with VAT regulations also increases the likelihood of a tax audit by the Revenue Department. The department may scrutinize your records for past years, looking for discrepancies or unreported income. This can result in further penalties, additional tax payments, and a lengthy audit process that can disrupt business operations. Frequent audits can also signal financial instability, which may harm your business’s reputation.


Business Losses

Without VAT registration, your business will be unable to issue tax invoices—a key requirement for businesses dealing with VAT-registered customers. This inability to provide official invoices can damage your credibility, as your clients or customers may not be able to claim back VAT from their own transactions. Furthermore, this may limit your ability to work with larger, more established companies that require proper VAT documentation for compliance and financial transparency.


Solution: Plan Your Taxes Properly—Don’t Wait for an Audit!

To avoid these severe consequences, it is crucial to manage your tax filings properly. Ensure you are aware of your VAT obligations and file your returns on time to maintain compliance with the Revenue Department. Proactively registering for VAT and submitting your tax returns on time not only helps you avoid fines and audits but also builds trust with your customers and clients. Don’t wait for a tax audit to force you into compliance—plan ahead and stay on top of your business’s tax responsibilities.
