Bookkeeping sounds complicated but it's manageable. This guide explains the basics - without jargon.

Why Bookkeeping?

Legal Requirement

• Every self-employed person must keep records
• Basis for the tax return
• You must prove everything during an audit

Your Own Benefit

• Overview of your finances
• See if you're making profit or loss
• Basis for better business decisions

EÜR vs. Balance Sheet

Income-Expense Statement (EÜR)

Sufficient for most self-employed!

You can use the EÜR if:

• You are a freelancer (always)
• You are a business owner with:

- Revenue under €600,000/year - Profit under €60,000/year

Advantages: ✅ Simple principle ✅ Less effort ✅ No inventory needed

Balance Sheet (Double-Entry Bookkeeping)

Mandatory for:

• Merchants (e.K., GmbH, AG, etc.)
• Business owners above the limits

More complex:

• Debit and credit
• Balance sheet + P&L
• Usually needs tax advisor

---

The Basic Principle of EÜR

   Business income (everything coming in)
 - Business expenses (everything going out)
 = Profit or Loss

Cash Basis Principle

Not relevant: Invoice date or delivery date!

Example

You issue an invoice on December 20, 2025. The customer pays on January 5, 2026. → The income counts for 2026!

Receipts: The Alpha and Omega

What is a Receipt?

Every proof of a business transaction:

• Incoming invoices
• Outgoing invoices (your invoices)
• Bank statements
• Receipts
• Contracts

The Golden Rule

"No posting without a receipt!"

Retention Periods

Digital or Paper?

Both are allowed! For digital storage:

• Store GoBD-compliant
• Archive immutably
• Don't throw away originals (for important documents)
