How It Works · the process

Tax determined where the work happens.

Five steps, from the moment a document is raised to the reporting it feeds — all of it inside SAP.
Taxmarc process flow

  1. Step 1: A document is raised

    A sales order, purchase order, or invoice is created in SAP, on the sales or procurement side.

  2. Step 2: Tax determination: the Agent gathers, the Core decides*

    Inside SAP, a Taxmarc component (the “Agent”) pulls together everything needed for a tax decision — customer, product, and transaction details already in SAP. That data is passed to the Taxmarc “Core,” which makes the actual tax call. For most countries, the Core runs within your SAP landscape. No separate system, no data leaving SAP.

  3. Step 3: The result lands in SAP's own tax fields

    The tax code, rate, and amount are written into SAP's standard tax fields (the same fields SAP always uses) so downstream posting and reporting work exactly as before.

  4. Step 4: The reasoning is recorded, and bad documents are stopped

    Every tax decision is logged, and if a document doesn't meet the rules, it's held before it can post, with an alert sent to the tax team.

  5. Step 5: The same data feeds reporting

    VAT returns, OSS, and Intrastat are generated automatically from that same underlying data — no separate reporting workstream.

Illustrative record — not a live determination.

* For US transactions, the Taxmarc Core integrates with CCH Suretax for rate look-up.

Scalability

Same process, same logic, regardless of country or number of legal entities — it scales without re-engineering per market.

Why it matters

Net effect: fewer manual corrections, an audit-ready trail by default, and non-compliant documents caught before they cost you a penalty.
