For companies, digitizing bank statements is not just a question of efficiency; legal obligation. Since the introduction of GoBD (principles for the proper management and storage of books, records and documents in electronic form), companies have had to digitize their accounting in an audit-proof manner.

In this guide, we compare all methods for digitizing account statements, explain the legal requirements and show you how to archive your account statements in a GoBD-compliant manner.

Important change in 2025

Since then January 1, 2025 The retention period for accounting documents (including bank statements) was increased from 10 8 years shortened (Fourth Bureaucracy Relief Act). This applies to both paper and digital statements.

Methods in comparison

There are three main methods of managing bank statements: paper, PDF and CSV. Each method has its advantages and disadvantages.

Method 1: Paper Bank Statements

The classic method: Account statements are obtained from the bank in paper form and archived in folders.

Advantages
  • ✓ No technical infrastructure required
  • ✓ Physically tangible and familiar
  • ✓ No dependency on software
  • ✓ Original document available
Disadvantages
  • ✗ High space requirement (archive room)
  • ✗ Time-consuming search
  • ✗ No machine evaluation
  • ✗ Danger of fire, water, loss
  • ✗ Manual booking required
  • ✗ High personnel costs

Important for paper archiving

You must also meet the GoBD requirements for paper archiving:

  • Organized storage: Chronological and comprehensible
  • Protection against loss: Fireproof cabinets, insurance
  • Access control: Authorized people only
  • Retention period: 8 years (since 2025)

Method 2: PDF statements

Bank statements are downloaded from the bank as PDF files or scanned paper statements are saved as PDF.

Advantages
  • ✓ No physical space required
  • ✓ Easy storage and backup
  • ✓ Faster search than paper
  • ✓ GoBD-compliant for German workflows where relevant (with proper archiving)
  • ✓ Protection against physical damage
  • ✓ Offered by most banks
Disadvantages
  • ✗ No machine evaluation
  • ✗ Manual booking required
  • ✗ No direct DATEV import
  • ✗ Time-consuming data extraction
  • ✗ Error prone when transferring manually

Method 3: CSV Statements (Recommended)

Bank statements are converted into structured CSV files that can be imported directly into accounting software.

Advantages
  • ✓ Can be evaluated automatically
  • ✓ Direct DATEV/Lexware import
  • ✓ Minimal time investment
  • ✓ No manual booking
  • ✓ Lowest storage requirements
  • ✓ Perfectly searchable
  • ✓ GoBD-compliant for German workflows where relevant
  • ✓ Error minimization
Disadvantages
  • ✗ Conversion required (one-time)
  • ✗ Not all banks offer CSV
  • ✗ Technical understanding helpful

Why CSV is the best choice

CSV files offer the perfect balance between legal certainty and efficiency:

90% time savings

Instead of 5 minutes/page, only ~30 seconds

Cost efficient

Graduated prices: 0,16 € - 0,08 €/page

Legal requirements (GoBD)

The GoBD (Principles for the proper management and storage of books, records and documents in electronic form) regulate how companies must keep their accounting records digitally.

6 core principles of the GoBD
  • Traceability: All bookings must be traceable
  • Immutability: No subsequent changes without a report
  • Completeness: All business transactions must be recorded
  • Timeliness: Timely recording (max. 10 days)
  • Order: Systematic filing and archiving
  • Availability: Readable and evaluable at any time
What does that mean practically?
  • ✓ Account statements must be made promptly (within 10 days).
  • ✓ Digital storage is a must unchangeable be (e.g. WORM memory)
  • ✓ All bank statements must completely be archived
  • ✓ Access only for authorized persons
  • Procedural documentation must be present
  • ✓ Everything has to be done during an audit available immediately be

Retention obligation

New retention period since 2025

Since then January 1, 2025 a shortened retention period applies:

8 years
Account statements as accounting receipts
(previously 10 years)
10 years
Annual financial statements, balance sheets
(unchanged)

When does the retention period begin?

The retention period begins not on the day of creation, but only with the End of the calendar year.

Example:

📅 Account statement created: March 15, 2024

🗓️ Deadline begins: January 1, 2025

Deadline ends: December 31, 2032 (8 years)

So you have to keep the bank statement until the end of 2032!

Audit-proof archiving

Audit-proof archiving means that your account statements are stored in such a way that they can withstand the requirements of an audit.

Immutability

Once saved, account statements may no longer be changed. Use WORM storage (Write Once, Read Many) or special archive systems.

Access control

Only authorized persons may have access to the archived account statements. Log all access.

Availability

Account statements must be legible and evaluable at all times. Regular backups are mandatory.

Recommended archive systems

  • Cloud archiving: Lexware archiving, DATEV DMS
  • Local systems: DocuWare, ELO Digital Office
  • Hybrid solutions: Combination of cloud and local

Frequently asked questions

Do I have to keep paper bank statements?

No, since 2025 digital retention has been fully GoBD-compliant for German workflows where relevant. You no longer have to keep paper account statements once you have digitized them in an audit-proof manner.

What is the difference between PDF and CSV?

PDF is an image format for people, CSV is a structured data format for machines. CSV can be imported directly into accounting software, PDF cannot.

What retention period applies to account statements?

8 years (since January 1, 2025, previously 10 years). The period begins at the end of the calendar year in which the account statement was created.

Can I digitize old paper bank statements?

Yes, you can scan old paper statements and save them as PDF or CSV. Audit-proof archiving is important.

What happens if the GoBD is violated?

Violations can lead to fines, back taxes and, in the worst case, the entire accounting being thrown out.

How long does it take to convert to CSV?

On average about 30 seconds per side. A 10-page bank statement is ready in about 5 minutes.

Conclusion & recommendation

Our clear recommendation: CSV

For modern companies this is CSV method the best choice. It combines legal certainty, efficiency and cost savings.
