Retention periods for billing records: what to keep and for how long

Retention periods for billing records: what to keep and for how long

Issuing the invoice correctly is only half of compliance; the other half is retaining the records properly for as long as the law requires. A compliant system takes care of this, but it is worth knowing the rules.

How long to keep them

Generally, formal tax retention obligations are tied to the four-year limitation period. However, prudence advises keeping them longer, because certain items (such as negative tax bases or depreciable investments) may be subject to review over longer periods, up to ten years.

In what format

Records must be kept guaranteeing their legibility, integrity and accessibility. In a compliant system, they are stored in a format that allows export and reading at any time, without depending on a specific software version.

Availability to the AEAT

As important as retaining is being able to make them available to the authority upon request, in the standard format foreseen. A compliant system enables this export immediately.

The importance of backups

Retention also means protecting against losses: disk failures, accidental deletions or incidents. Regular backups and, preferably, cloud retention ensure records are not lost.

Conclusion

Keeping records for the legal periods, in an accessible format and with backups, is an essential part of compliance. Issuing correctly is not enough: you must be able to prove it years later. Invoseal keeps your records securely and always available for export.
