@wannapasrihong-g , I am still awiting your response for my request for more info. However, IMHO,
your Crypto broker / entity is giving you a lot of garbage. My response is applicable to foreign persons with US sourced/ connected incomes ( disposal of assets , passive incomes etc. ), not specific to crypto only.
1. There is no requirement to pay taxes before the entity can disburse the proceeds of the sale.
2. What is supposed to happen is ---(a) the entity effects the sale of the asset ; (b) if the owner is foreign person, entity, trust etc., then the broker MUST withhold 30% tax ( nominal amount) and either directly or using an approved agent , deposit the withheld taxes to the IRS, and the rest to the foreign owner; (c) issue a form 1041-S/T to the recipient along with informational copy to the IRS within the first 15/ 31 days of Jan of the following year.
Therefore the question is why are they not doing their job and asking you come to the USA and go through the tax procedure. There is no such requirement --- only requirement for the foreign investor is to have taxes withheld before distribution and for the foreign tax payer to file a tax return to affect reconciliation of the withheld taxes.
The broker's requirements are substantially the same for a US investor except for withholding requirement.
Please see Pub 515
I await your response
