Just to say that only the other day, the young man in the main Udon Revenue Office (and perhaps the only officer with reasonable English!) gave me to understand that my pink ID card could be used for tax return purposes. I may be mistaken here, but my understanding and surprise was that the National ID number and TIN number are the same. He actually took the pink card and went to the computer. Whether he was checking the validity of the card, or activating the number on the TRD database at this time, I don't know.
Maybe someone can explain the process. If you are eligible to pay tax, do you have to 'pay up' first and then reclaim it subsequently under DTA? Again, the Udon guy suggested there was another building where the latter was dealt with.
He was activating your Thai ID number on the TRD database.
The process of submitting a tax return is that.
1) you discover all the allowances you are eligible for on the Thai tax system plus the zero rated tax band, this is a variable number ranging from ฿210,000 to upwards of ฿600,000 (do not forget the Thai bank withholding tax as a credit)
2)Then you calculate all your remittances
3) Then you decide if the remittances are assessable for Thai tax or not.
4) Then you calculate the tax you may have paid on the assessable remittances and add that as a virtual deduction from any Thai tax due
5) You then submit your return and either 1) get a refund 2) pay the amount of tax you have calculated or 3) do nothing and get nothing because you are not required to pay any tax.
TLDR you are responsible for calculating your tax liability, do not expect that a Thai tax official will understand the vagaries of your home tax system, the
Thai tax office will assist you in completing your form there is absolutely no guarantee that they will know enough to reduce your tax to the minimum. It is also quite possible that they will not understand the English text of the DTA (FWIW many English native speakers have difficulty in understanding the DTA’s so its not surprising that a Thai official also has problems)
As you can see specially for most foreigners it is easy to make mistakes and pay too much or not enough.
There are tax specialists who will assist, the fees they charge are there for good reason. They maybe worthwhile. They usually start at about ฿7,000. Only you can judge your abilities and confidence in your knowledge of the tax laws.
Pay too much and it’s possible you can file an amended return and get a refund
Pay too little (or nothing) and there are penalties that depending on the individual case include heavy fines and can include being an involuntary guest in a government facility. However genuine mistakes may not even incur a fine, just payment of the missing tax.
