Taxes by country

Thuta POS applies the right tax automatically based on your country. You set this up once during registration (or in Settings) and the POS, guest ordering, and receipts all use it.

Myanmar (MMK)

• Single tax rate.
• Currency shown with no decimal places.
• Tax registration field: Commercial Tax registration number.

Thailand (THB)

• Single VAT rate.
• Currency shown with two decimal places.
• Tax registration field: VAT registration ID.

Japan (JPY)

• Dual rate under the reduced tax-rate system:
• Dine-in — 10%
• Takeout — 8%
• Currency shown with no decimal places.
• Tax registration field: Qualified invoice registration number (登録番号).

Because Japan has two rates, the POS terminal shows a dine-in / takeout toggle so you choose the correct rate per order. See [Using the POS terminal](/docs/pos).

How tax is calculated

• Prices and tax are computed in the smallest currency unit (no floating-point

rounding errors).

• Tax rates are stored as basis points internally, so multi-rate countries like

Japan are handled exactly.

• For tax-inclusive pricing, the tax portion is derived from the gross price; for

tax-exclusive pricing, tax is added on top. The configuration is set per branch.

Mock data for testing

While testing, use a mock tax registration number — for example a placeholder qualified-invoice number — rather than a real business's actual number. Replace it with your real number before going live.
