How long does your business need to keep an electronic invoice? The answer depends entirely on where that invoice was issued, and it varies more than most finance teams realise.
Across the world’s major tax jurisdictions, mandatory retention periods for e-invoices range from four years to over a decade. Get it wrong, whether through early deletion, format changes, or switching providers without migrating records and the consequences range from failed VAT recovery to financial penalties and heightened audit risk.
This guide sets out the retention requirements that apply across key markets, the technical standards archives must meet, and how to build a strategy that holds up across multiple jurisdictions.
Many finance teams treat invoice archiving as a housekeeping task, something to do when storage space runs low or a new system is implemented. In reality, document retention is a statutory obligation in almost every country that levies VAT or a comparable consumption tax, such as GST. Tax authorities do not merely encourage businesses to keep their records; they require it, and they set precise timelines and retention rules.
The legal basis for these requirements varies by jurisdiction. In the EU, Article 245 of Council Directive 2006/112/EC, the principal EU VAT Directive, requires member states to ensure that invoices are stored for a minimum period determined by each state, while also permitting electronic storage subject to conditions around authenticity and integrity. These are standard regulations that each state is to impose. In the United States, the Internal Revenue Service (IRS) sets its own recordkeeping expectations under the Internal Revenue Code and associated guidance. In the Asia-Pacific markets, national tax codes impose similarly binding obligations.
The penalties for non-compliance can be severe. Depending on the jurisdiction, businesses that cannot produce invoices on demand during a tax audit may face financial fines, denial of input VAT deductions, and in cases of deliberate destruction, criminal liability. For businesses that reclaim VAT on foreign purchases, missing documentation can mean permanent loss of that refund. Given these stakes, electronic record management is a legal priority.
Across the world’s major tax jurisdictions, mandatory invoice retention periods cluster in a five-to-ten-year band, though there are notable exceptions in both directions.
Five years is the most common lower boundary, found in markets including Australia, Singapore, and several EU member states. Seven years appears frequently across Europe and is the standard in the United Kingdom following its departure from the EU. Ten years is the requirement in a number of markets, including Germany, and is also common across Latin America. Some jurisdictions extend obligations even further: in Brazil, certain fiscal documents must be retained for up to twelve years depending on the tax type involved.
Although EU law sets a harmonised framework under the VAT Directive, each member state has implemented its own specific period. A business operating in both France and Poland, for example, faces different national rules despite both countries sharing the same EU legal foundation.
Understanding the general landscape is useful context, but businesses need jurisdiction-level precision when building a compliant document retention policy.
The cards below summarises archiving periods and key conditions for e-invoices across major markets. All figures represent minimum legal requirements. Businesses may choose to retain records beyond the legal minimum for commercial or dispute-resolution purposes.
Records must be stored in an unalterable, machine-readable format. The GoBD principles govern electronic archiving.
Electronic invoices must be stored in their original format and remain accessible throughout the period. France's mandatory e-Invoicing rollout introduces additional platform-specific archiving requirements from 2026.
Italy's Sistema di Interscambio (SdI) platform retains copies for 15 years, but businesses are independently responsible for their own 10-year archive.
Spain applies a four-year general tax statute of limitations to invoice retention. Invoices related to assets subject to amortisation must be kept for four years following the end of the amortisation period.
Real estate-related records must be kept for 10 years. Electronic invoices may be stored abroad provided the Dutch tax authority retains access.
HMRC requires VAT records, including invoices, to be kept for six years. Records related to capital assets may require retention for up to ten years under the Capital Goods Scheme.
The IRS generally recommends three to seven years depending on the circumstances. Some states impose separate and longer obligations. Records related to property must be kept until the statute of limitations expires for the year of disposal.
The Australian Taxation Office (ATO) requires business records to be kept for five years from the date of preparation or the date of the transaction, whichever is later.
NF-e (Nota Fiscal Eletrônica) XML files must be retained for five years as a minimum; certain fiscal obligations extend this to twelve years. SPED records follow their own separate timetables.
Under the GST framework, registered taxpayers must retain records for seventy-two months (six years) from the due date of the annual return, though some authorities interpret effective retention requirements as eight years from the transaction date.
The Inland Revenue Authority of Singapore (IRAS) requires records to be kept for five years from the relevant Year of Assessment.
Under the Electronic Books Preservation Act (amended 2022 and further updated for 2024), electronic invoices must be retained for seven years as a general rule; loss-carry-forward situations can extend this to ten years.
Retaining invoices for the correct duration is only half of the compliance equation. Tax authorities also impose specific technical standards governing how those records must be maintained. Digital invoice storage that meets the time requirement but fails the technical standards is still non-compliant.
Authenticity and integrity. Most jurisdictions require that archived invoices be unaltered from the moment of issue. In the EU, Article 233 of the VAT Directive requires that the authenticity of origin and the integrity of content of invoices be guaranteed throughout the storage/archiving period. Acceptable methods include qualified electronic signatures and electronic data interchange (EDI) systems, as well as reliable audit trails that link each invoice to the underlying commercial transaction.
Readability and accessibility. Records must remain legible and interpretable for the full retention period. Storing invoices in a proprietary format that becomes obsolete, or in a system that is decommissioned, does not discharge the obligation. Tax authorities in Germany, France, and Japan, among others, explicitly require that records remain machine-readable and accessible for retrieval on demand without significant delay.
Storage location restrictions. Some jurisdictions restrict where electronic records may physically reside. Several EU member states require that invoices stored on servers outside their territory, must remain accessible to the national tax authority at all times. Some even require prior notification or approval before records are moved offshore.
Format preservation. Where an invoice was originally issued in a structured XML format, such as Italy’s FatturaPA or Germany’s XRechnung, the archive must retain the original structured file, not merely a visual rendering. Converting an XML invoice to a PDF for archival purposes may invalidate the record in jurisdictions that require preservation of the original format.
Early deletion or accidental loss of invoices creates several categories of risk that can far exceed the storage costs of retaining them properly.
Financial penalties. Most tax authorities impose fines for failure to maintain required records. In Germany, penalties under the Abgabenordnung (Tax Code) for recordkeeping violations can reach €250,000. In the UK, HMRC can issue penalties of up to £3,000 per tax period for failure to keep adequate VAT records. In Brazil, penalties related to missing NF-e records can include both fixed fines and a percentage of the transaction value.
VAT recovery failure. For businesses that recover VAT on purchases including foreign VAT refunds. The invoice is the primary evidentiary document. Without it, a claim cannot be substantiated. Tax authorities routinely reject VAT reclaim submissions where supporting invoices cannot be produced, and the financial implication escalates over time as multiple periods’ worth of unrecoverable input tax accumulates. Businesses managing cross-border VAT reclaims are particularly exposed.
Audit exposure. A tax audit that uncovers missing invoice records, even if the underlying transactions were fully compliant, typically prompts deeper scrutiny. In some jurisdictions, the burden of proof shifts to the taxpayer to demonstrate that a deleted transaction was properly accounted for.
Supply chain and commercial risk. Beyond the tax dimension, early deletion can affect a business’s ability to resolve commercial disputes or assert warranty claims.
For businesses operating in multiple countries, a single-jurisdiction approach to e-invoice retention is impossible, due to the various respective requirements. A robust multi-jurisdictional strategy requires deliberate design across several dimensions.
1. Does the archiving period start from the invoice date or from the end of the tax year?
This varies based on jurisdictional requirements. In the UK and Germany, the retention period generally starts from the end of the fiscal year in which the invoice was issued, not from the invoice date itself.
2. What are a business’s obligations if it switches e-invoicing providers before the archiving period ends?
The archiving obligation remains with the business regardless of their selected provider. Before switching providers, businesses must ensure all historical invoices are either migrated to the new system or retained in an accessible alternative archive.
3. If a business is acquired, who becomes responsible for the archived invoices?
In most jurisdictions, tax obligations transfer to the acquiring entity or successor as part of the business transfer. The acquiring company becomes responsible for maintaining the seller’s archives for the remainder of their applicable retention periods. Due diligence processes should verify that archives are complete, accessible, and technically compliant.
4. Can businesses store e-invoices in the cloud and still meet retention requirements?
Yes, in certain jurisdictions, provided the cloud solution meets the applicable technical and access standards imposed. Key general requirements include, data integrity, audit logging, unaltered format preservation, and the ability to produce records on demand. Some countries require a provider of such a service to be accredited to do so, much like providing e-invoicing services.
5. Does the archiving obligation apply to invoices of transactions that were reversed or credited later?
Yes. Invoices for reversed or credited transactions must generally be retained alongside the associated credit notes for the full applicable period. Tax authorities may need to review the complete documentary chain, as to verify that adjustments were correctly reported.
