From Tax Returns to Legal Documents: What Important Files to Keep (and for How Long)

Storing documents is more than simply placing them on shelves or cabinets. In Ireland, there are several regulations around safely storing items, the length of time required for storage, as well as how to properly dispose of them.
Businesses in Ireland need to comply with government tax regulations as well as the General Data Protection Regulation (GDPR) obligations. Poor document management can expose you to unnecessary risks, such as fines. With secure storage solutions, managing paperwork becomes far more straightforward.
Business and Tax Records You Must Keep
In Ireland, Revenue requires businesses to keep key financial and tax-related records for at least six years. These documents must clearly demonstrate how figures in tax returns were calculated and should be available if they’re requested.
Common records that your company has to keep include:
- Receipts for expenses and purchases
- Sales invoices
- Accounting books and nominal ledgers
- Bank statements and supporting documentation
- Any ‘linking documents’ used to calculate Income Tax, Corporation Tax, or Capital Gains Tax
While digital storage is permitted in many cases, businesses remain legally responsible for record keeping, even if an accountant or agent manages records on their behalf. Where original documents are required by legislation, these must be retained in their original format – which means significant storage space!

Legal, Property, and Professional Documentation
For solicitors, property professionals, and businesses handling legal documentation, document retention periods are often longer and more complex. Files should generally be retained for at least the relevant Statute of Limitations period, protecting both the client and your firm.
Examples of common retention requirements include:
- Conveyancing Files: Minimum of 13 years after file closure
- Solicitors’ Accounting Records: At least 6 years
- Anti-Money Laundering Records: Minimum of 5 years after the end of the client relationship
- Probate and Wills: Often retained indefinitely
- Employee Records: Varying periods depending on the document type
Certain files - such as those involving minors, mentally incapacitated persons, or litigation holds - may require indefinite retention, which means you need to find space to store these for extended periods.
GDPR and Data Protection Obligations
GDPR adds another layer of responsibility when it comes to storing sensitive documents. Personal data cannot be kept longer than necessary unless there is a lawful reason to do so, such as compliance with tax, legal, or regulatory requirements. Failure to manage this properly can result in data breaches, reputational damage, and significant fines for your company.
To remain compliant, you must:
- Clearly define document retention periods
- Inform clients how long their data will be held and why
- Maintain a documented retention and destruction policy
- Securely destroy files once statutory periods expire
Why Choose Off-Site Document Storage
Storing documents onsite may seem convenient and more cost-effective, but it often creates hidden risks. Basements, storerooms, and filing cabinets are not designed to protect sensitive records from external dangers such as damp, fire, theft, or unauthorised access. Professional off-site storage offers a safer and more efficient alternative, especially for archived or infrequently accessed documents.
