If your business files VAT across multiple European countries, reconciliation isn’t a “nice to have”—it’s the control that keeps your returns defensible, your ledgers accurate, and your audits uneventful. This guide explains why VAT reconciliation is critical, the data you need, common pitfalls, and a step-by-step method you can roll out immediately.

Why VAT Reconciliation Matters
- Compliance & accuracy: Aligns VAT returns with the general ledger and subledgers so filings reflect economic reality.
- Audit readiness: Creates a clear audit trail from each return figure to source transactions.
- Cashflow & risk: Avoids penalties, late interests, and cashflow surprises caused by misstated input/output VAT.
- Cross-border complexity: Normalizes multi-currency, multi-rate VAT and marketplace/OSS/IOSS scenarios into one consistent view.
The Core Data You’ll Need
- General Ledger VAT control accounts (output/input VAT), revenue, expense, adjustments.
- Sales & Billing systems (invoices, credit notes, returns, marketplaces/PSPs).
- Purchases (AP, expense tools, POs, import VAT, reverse charges).
- Bank/PSP settlement statements to confirm cash vs. reported VAT.
- VAT Return Drafts and working papers for each jurisdiction/period.

Step-by-Step: A Practical VAT Reconciliation Method
1) Scope & calendar
Define countries, filing frequencies, deadlines, and data owners. Build a reconciliation calendar with due dates and handoffs.
2) Extract & normalize
Pull GL and transaction data for the period. Normalize tax codes, rates, currencies, and document types (invoice/credit note/return).
3) Map VAT codes to return boxes
Create a controlled mapping table (by country) from tax codes to return fields (e.g., outputs, inputs, intra-EU supplies, reverse charge). Store in a central repo and apply change control.
4) Prepare ledgers vs. return
- Summarize GL by VAT control accounts.
- Summarize transactions by VAT code → return box.
- Compare both to the draft return totals. Differences must be explainable.
5) Investigate & resolve variances
Typical root causes: timing cut-offs, duplicates, wrong tax codes, missing credit notes, exchange rate mis-applications, rounding. Post journals or correct source records as appropriate—document all corrections.
6) Evidence pack
Produce a reconciliation pack per country/period:
- Period GL extracts (signed off)
- Transaction summaries by VAT code/box
- Variance analysis & corrections
- Copies/samples of invoices and import docs
- Management sign-off
7) Lock & archive
Lock folders, version documents, and archive securely for statutory retention.
Common Pitfalls (and Fixes)
- Mixed tax coding in one product/service: Enforce tax code rules at SKU/service and customer level; add validation on invoice creation.
- Marketplace & PSP fees netting VAT: Build fee/VAT extraction from PSP statements; don’t assume net deposits equal taxable sales.
- Reverse-charge confusion: Train AP teams, set default codes for cross-border services/goods, and automate self-assessment entries.
- Credit notes missing in the period: Reconcile returns with credit note logs; post accruals if necessary.
- Foreign currency differences: Use consistent month-end or transaction-date FX per policy and disclose methodology.
Controls & Documentation Finance Teams Should Keep
- VAT code dictionary per country with definitions and examples.
- Change log for VAT mappings and rates.
- Maker-checker sign-off on reconciliations (pre-filing).
- Variance thresholds (e.g., investigate any variance >0.5% of outputs).
- Retention policy and secure archive (read-only after sign-off).
