Tax in Thailand

Hi all,

My partner has been offered a job to work in Bangkok for a year, but was wondering how much the tax will be? The annual salary will be about 3.5 million baby's, which I can see is taxed at 30%, but will also possibly have bonus. Someone said that you can claim tax back? Is this possible?

Thanks in advance for any advice.

Found this on the internet, still looks quite relevant
