Remittance Source Analysis & FIFO Reconstruction

Clear Analysis for Complex Remittances
and Foreign Income

This service is for expats whose Thai tax filing involves complex overseas transfers, mixed accounts, investment disposals or unclear sources of funds.

When money has moved between bank accounts, investment platforms and Thailand, it may not be enough to simply add up the amount remitted. The source, timing and type of funds may need to be reviewed before your tax return can be prepared accurately.

Remittance Source Analysis & FIFO Reconstruction helps identify what has been remitted, where it appears to have come from and how it may be treated for Thai tax filing purposes, based on the records provided.

It can be arranged as a separate service or added during tax filing if our team identifies that further analysis is needed.
