The difference between tax categories TTX1 and MWST.

Hello,

Regarding the tax determination of sales order, the default tax category has changed from MWST to TTX1, but what are the differences between these two tax categories?

Hello dear user,

And thank you for asking your question on the SAP Community blog.

In SAP S/4HANA Cloud Public Edition, the tax category (like MWST or TTX1) controls how tax conditions are applied during pricing and tax determination especially in Sales Orders.

Here are the main difference between MWST and TTX1:

Tax Category	Meaning	Common Use	Notes
MWST	Mehrwertsteuer (VAT)	Traditional default VAT tax category in many systems	Used in classic tax configurations
TTX1	Advanced Tax Determination Tax Category 1	Used with the Advanced Tax Determination engine	Supports automated, flexible tax setups in Public Cloud

Why is TTX1 now used by default?

In S/4HANA Cloud Public Edition, SAP is increasingly shifting from MWST to TTX1 to support:

• Advanced Tax Determination (ATD) via tax condition records
• More standardized tax logic across countries
• Compatibility with SAP Document and Reporting Compliance (for e-invoicing)

Summary:

Aspect	MWST	TTX1
Legacy	Yes	No
Used in Cloud Public	Legacy only	Recommended
Customizable	Limited	Highly flexible via Manage Tax Codes app
Preferred by SAP	No longer default	Yes, especially in Public Cloud

What to do:

• If you're still using MWST in some materials or customers, you might want to standardize to TTX1.
• Use the "Manage Tax Categories" and "Manage Tax Codes" apps to maintain mappings.
• Maintain condition records via App: Set Tax Rates for Country/Region (App ID: F4075).

I hope my explanation is clear enough and answer your main questions.

Best regards,

Jeremy
