Disclosure

ThonExpat is a decision aid. It shows dated legal parameters and estimates a tax position. It does not prepare returns, represent you before a tax authority, or give personalised professional advice.

What your tools do

• Your file compiles passport × purpose × stay into dated cells you can save and share.
• The calculator refuses when a parameter is past its refresh window.
• Ref sheets show cells with source and check date. Empty fields stay empty.

Money

The app stays free for you. When we introduce you to a Vietnam lawyer, that referral may be sponsored and disclosed here the same day it goes live.

Some future steps (preparer, cover, transfer) may earn ThonExpat a referral fee — always marked sponsored. Fact cells never change because of a fee.

Live referrals

None live yet.

You use the tools first. Counsel signs off. ThonExpat does not run the lawyer's file.
