Tax Management

What's included

Every feature below runs on the same SYNE One data layer - shared with every other module on the platform.

Multi-Jurisdiction VAT & GST

Tax rates, rules and exemptions applied automatically based on supplier location, buyer location, goods classification and transaction type - across 100+ countries. No manual rate tables, no mis-coded transactions.

CBAM Embedded Carbon Tax

For EU importers, SYNE One calculates the embedded carbon cost of every cross-border purchase against current CBAM rates - integrated with supply chain traceability data. Declarations are pre-populated from verified source data, not estimates.

Transfer Pricing Documentation

For inter-entity transactions, SYNE One applies your configured transfer pricing policy and generates contemporaneous documentation - reducing audit risk and compressing annual compliance from weeks to hours.

Withholding Tax & Reverse Charge

Withholding tax obligations on supplier payments and reverse charge VAT on cross-border services are identified and applied at invoice level - with the correct accounting entries posted and statutory reports pre-populated automatically.

One-Click Tax Returns

VAT and GST returns pre-populated from transaction data. Export directly to ATO (AU), IRD (NZ), MTD (UK), ELSTER (Germany), IRAS (Singapore) and iTax (Kenya) formats - or generate XML or XBRL for any standard e-filing system.

Real-Time Calculation at Transaction

Tax is applied at the exact moment an invoice is created - not post-processed in batch. Every transaction carries a complete tax calculation audit trail from the moment it is issued, making regulatory inspection straightforward.

Lodge Returns Online

Submit VAT, GST and income tax returns directly to the authority from inside the platform - not just a generated file you still have to upload elsewhere. Lodgement status and confirmation receipts stay attached to the filing record.

Exchange Data With Tax Authorities

Direct data exchange with tax authorities where available, in the format each authority expects - reducing manual re-entry and the risk of a mismatched filing at audit time.

Built for every role

What Tax Management changes, seat by seat.

The same module reads differently depending on who's using it - standard, role-based access covers each of these out of the box, and your business can create any custom role on top.

Tax Manager

Multi-jurisdiction VAT/GST and CBAM calculations automated at source, not reconstructed at filing time.

CFO

Zero retroactive tax corrections, because rules update automatically as regulations change.

Finance Team

Transfer pricing documentation generated from the same transaction data used for financial reporting.

External Tax Advisor

A consistent, auditable data set instead of reconciling exports from multiple entities.

Filing Preparer

Access scoped to preparing and reviewing returns before lodgement, without visibility into unrelated financial data.

Internal Auditor

Read-only access to every tax calculation and filing record, without the ability to alter a return already submitted.

Connected to the rest of the platform

Tax Management doesn't work in isolation.

Data entered here is read directly by the rest of SYNE - many-to-many, not a chain - no export, no re-entry, no separate reconciliation.

F&
Finance & Accounting

Every transaction already carries the tax treatment it needs - nothing is recalculated after the fact.

ST
SYNE Trust

CBAM embedded-carbon calculations draw on the same verified origin and emissions data used for traceability.

PR
Procurement & RFx

Purchase orders carry the tax treatment they'll need before they ever reach accounts payable.

ES
Enterprise Sustainability

CBAM declarations and carbon-tax exposure feed the same disclosure evidence used for regulatory reporting.

PA
Professionals & Advisors

An external tax consultant works from the same live filing calendar and evidence trail, not a separate export.

In practice

An importer newly exposed to CBAM reporting obligations

The challenge

Embedded carbon calculations for imported goods had to be manually assembled from supplier declarations of uneven quality.

CBAM exposure is now calculated automatically from verified supply-chain emissions data, with no manual assembly required. Origin and emissions evidence comes straight from SYNE Trust's traceability records; the same figures feed Enterprise Sustainability's disclosure reporting; and for the first filing cycle, the business used Professional Services to validate the methodology before relying on it unsupervised.
