no of course not, that's not how taxes work. You have pay tax yourself and file a return. Enforcement will be the same as any other country through an audit system.
ah.... what... the change last year to broaden what foreign income is assessable it was finalized last year, it was published in gazette. Understand that is not a legislative change of section 41, it is a reinterpretation of the existing law. So yes it is finalized, most perso al remittance into Thailand by a tax resident is taxable today. If you talking about the purposed law to tax worldwide income, that is not law and we have little details on the legislation, but it seem extremely like to pass as it appears to be the succession plan of the changes last year.
You can't gift someone in Thailand without bring that money into Thailand first. If she has an account outside of Thailand, gift it there and let her bring it in to Thailand. I am sure people claiming gift will get a scrutiny by RD.
definitely no definition on specific foreign accounts at this time, it's possible in the years to come they put some general guidance notes though. There still a lot a grey area to pension, investments, and credits...just have to wait for how the RD will apply the law.
If you are shopping for tax experts, I would find a company that's been around for a while and has a good reputation. A lot of new companies catering to foreigns are try to get the most money out of you using preditory practices.
the term resident here should still apply even if you didn't meet Australias domestic law of tax resident. The treaty defines resident differently, you would always claim residency on both side. The competing clause of tax agreement is just priority ordering, you are not only ever have to be defined as a tax resident of a single state.
I don't know specific Aussie retirement/annuity types. What the Australian government classifys it as is the probably your more weighted option.
Given that this a new thing for thailand, applications of the law will take a while to be settled. There definitely still a lot of grey areas.
1. Subject to the provisions of Article 19, pensions and annuities paid to a resident of one of the Contracting States shall be taxable only in that State.
2. The term "annuity" means a stated sum payable periodically at stated times during life or during a specified or ascertainable period of time under an obligation to make the payments in return for adequate and full consideration in money or money's worth
Australia has a very preferential tax treaty, in that all forms of Australian pensions are not assesable in Thailand. This is not true any other country where it's typically limited to government pension only.
