Employee's Social Security Fund contribution (Sec. 33): 5% of wages, wages taken as at least 1,650 and at most 17,500 a month (2026-2028 ceiling), fractions of a baht rounded half up. Computed from the Basic earning rather than `base` so a partial month is 5% of the wages actually paid and the ceiling applies after proration. The contribution is deductible from taxable income in full, so the component is exempted_from_income_tax. Withheld amounts are held in "Social Security Payable" (ประกันสังคมค้างจ่าย) until remitted. Created once a Thai company exists (Company.on_update, install hooks, scheduler, the setup_salary_components patch); the Salary Component validate hook links every Thai company.

Installation
You can install this app using the bench CLI:
cd $PATH_TO_YOUR_BENCH
bench get-app $URL_OF_THIS_REPO --branch develop
bench install-app default_thai_company
Thai language
Every string the app adds (custom field labels, messages, print format and letter head
text, Tax Withholding Category names) is translated in translations/th.csv; the same
file overrides the upstream Thai for the standard labels the print formats show. The
print formats embed Sarabun (public/fonts, OFL) so PDFs render Thai on servers
without a Thai system font. Switch a user or the print language to th to use it.
Addresses in more than one language
Address lines, city, county and state are translatable: the Address form shows a translate
button next to each, which stores the other language in a Translation record. The Thailand
Address Template renders those fields through _(), so the print formats and letter head
show the company's and the party's address in the document's print language (the company
address is re-rendered at print time; party addresses are re-rendered from the linked
Address instead of printing the stored address_display). The withholding tax certificate
always takes the Thai translation. Translations are keyed on the exact text, so one
translation of a city or province serves every address that uses it. The same goes for
the bank details on the Sales Invoice: Account Name on the Bank Account and Bank Name
on the Bank are translatable.
Withholding tax certificate
A paid Purchase Invoice with Apply Tax Withholding Amount gets a Withholding Tax Certificate
button that downloads the Revenue Department's Sec. 50 bis form (หนังสือรับรองการหักภาษี ณ ที่จ่าย,
two copies) as a PDF: the Withholding Tax Certificate print format lays the invoice's data
over the official form (public/images). The row the payment is reported on comes from
Type of Income Paid on the Tax Withholding Category (set for the shipped categories; pick it
for your own), and the ภ.ง.ด. return is ticked from the Supplier's type: ภ.ง.ด.53 for juristic
payees, ภ.ง.ด.1ก / 2 / 3 by income type for individuals. เล่มที่ / เลขที่ (certificate book
numbers) and ลำดับที่ (the line in the return) are left for the accountant.
