Keeping accurate accounting is one of the keys to the success of any business. However, many self-employed professionals and SMEs make accounting mistakes that can lead to penalties, financial losses, and poor decision-making.
In this article, we explain the most common accounting errors, their consequences, and—most importantly—how to avoid them easily.
📌 Why is good accounting so important?
Accounting is not just a legal obligation. It is also a strategic tool that allows you to:
- Understand the real financial situation of your business
- Control income and expenses
- Optimize taxes
- Plan investments
- Avoid penalties
In the Canary Islands, there are also specific tax features such as IGIC, which make specialized accounting management even more important.
🚨 Most common accounting mistakes
1. Not recording all income and expenses
One of the most frequent mistakes is failing to record all business transactions.
Why does this happen?
- Lack of time
- Disorganization
- Lack of knowledge
- Manual management without a system
Consequences:
- Unrealistic financial results
- Tax errors
- Risk of penalties
2. Mixing personal and business accounts
Many self-employed individuals use the same bank account for personal and business purposes.
Problems this causes:
- Loss of financial control
- Difficulty justifying expenses
- Errors in tax returns
3. Not reconciling bank transactions
Bank reconciliation consists of checking that bank movements match accounting records.
Common errors:
- Duplicate payments
- Unrecorded income
- Forgotten expenses
4. Not closing accounts monthly
Many businesses only review their accounting when it’s time to file taxes.
Risks:
- Accumulated errors
- Lack of financial control
- Cash flow problems
5. Not properly keeping documentation
In Spain, it is mandatory to keep accounting and tax documentation for at least 4 years.
Article 30 of the Commercial Code states that entrepreneurs must keep books, correspondence, documentation, and supporting records related to their business, properly organized, for six years from the date of the last entry in the books, unless otherwise established by general or specific provisions.
This period does not coincide with the statute of limitations (4 years) for the Tax Administration to determine tax liabilities, meaning that even if a tax is no longer subject to review, the entrepreneur may still be required to retain accounting records.
Additionally, tax inspections may extend to prescribed years if those records have effects on non-prescribed periods (Art. 115 General Tax Law). In cases involving tax credits or deductions, the Administration has up to 10 years to verify their validity (Art. 66 bis.2 LGT).
Ceasing business activity does not exempt the entrepreneur from this obligation. In case of death, the responsibility falls on heirs. In the event of company dissolution, the liquidators are responsible for compliance.
Key documents:
- Issued invoices
- Received invoices
- Bank statements
- Contracts
- Payroll records
6. Incorrect application of VAT/IGIC
In the Canary Islands, VAT does not apply; instead, IGIC (Canary Islands General Indirect Tax) is used, which often causes confusion.
Common mistakes:
- Applying incorrect rates
- Incorrect filing
- Confusing IGIC with VAT
