Support this site
This site is free, needs no account, has no paid tier, and will stay that way. Every calculator and the AI question box work identically whether or not anyone has donated.
If it saved you time or made a decision easier and you would like to chip in towards the running costs, this page shows how. If not, that is completely fine.
Bank transfer
Public bank details and payment QR codes are temporarily unavailable. You can still support the site by sharing a tool or reporting an issue through the contact page.
Where the money goes
- — The annual domain renewal, roughly 400 baht a year.
- — Hosting and the AI assistant, which currently sit inside free usage tiers. If traffic grows past those tiers, this is what covers the overage.
- — The time spent checking tax rates and government fees against the authorities’ own websites — work that has to be repeated every time the law changes.
What a donation does not do
- — It does not remove ads or unlock anything, because everything here is already open to everyone.
- — It has no influence on the content. Figures and explanations stay sourced from the responsible Thai authority, exactly as before.
- — It does not buy advice. This is not an accounting firm, a tax advisory or a law firm.
Ways to help that cost nothing
- — Send a link to whichever page helped you to someone who is looking into the same thing.
- — If you spot a figure that is wrong or out of date, tell us through the contact page. That is worth more to this site than a donation.
- — Tell us which calculator you wish existed. Requests from actual users are where most new pages come from.
Thank you for using the site.
