Every feature below runs on the same SYNE One data layer - shared with every other module on the platform.
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.
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.
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 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.
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.
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.
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.
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.
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.
Multi-jurisdiction VAT/GST and CBAM calculations automated at source, not reconstructed at filing time.
Zero retroactive tax corrections, because rules update automatically as regulations change.
Transfer pricing documentation generated from the same transaction data used for financial reporting.
A consistent, auditable data set instead of reconciling exports from multiple entities.
Access scoped to preparing and reviewing returns before lodgement, without visibility into unrelated financial data.
Read-only access to every tax calculation and filing record, without the ability to alter a return already submitted.
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.
Every transaction already carries the tax treatment it needs - nothing is recalculated after the fact.
CBAM embedded-carbon calculations draw on the same verified origin and emissions data used for traceability.
Purchase orders carry the tax treatment they'll need before they ever reach accounts payable.
CBAM declarations and carbon-tax exposure feed the same disclosure evidence used for regulatory reporting.
An external tax consultant works from the same live filing calendar and evidence trail, not a separate export.
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.
"CBAM went from a looming compliance risk to a number that just appears correctly." - Head of Tax, industrial importer
Accurate, current tax treatment keeps landed costs predictable - customers see stable pricing instead of retroactive surcharges from a corrected filing.
