Common VAT Mistakes (and How to Avoid Them)
VAT (Value Added Tax) is everywhere — and it’s more complex than it seems.
Whether you’re running a small business, managing a finance department, or handling client accounts, VAT is probably part of your daily operations.
But despite how routine it becomes, it’s still easy to make mistakes — and those mistakes can lead to costly consequences: tax audits, penalties, and time-consuming corrections.
Here are three of the most common VAT errors — and how to avoid them with a few good habits.
❌ Mistake #1: Applying the Wrong VAT Rate
It may seem straightforward: apply 20% VAT, done.
But in reality, the standard rate isn’t always the correct one. In many cases, a reduced rate applies — 10%, 5.5%, or even 0%, depending on the product or service and local tax legislation.
🔍 Example:
Let’s say you run a restaurant.
- A takeaway meal is taxed at 10%
- But if the customer eats on site, it’d jumps to 20% depends on the meal consumed
Misclassifying the nature of the sale means applying the wrong rate — and that’s a red flag during an tax audit.
✅ How to avoid it:
- Keep a reference sheet or digital tool that lists current VAT rates by activity or product.
- Train your sales, billing, and accounting teams on rate differences.
- For international or niche transactions, consult your tax advisor — or even your local tax authority — before applying a rate.
❌ Mistake #2: Deducting input VAT without a Valid Invoice
Many businesses wrongly assume that all incoming expenses with VAT are deductible. But in reality, VAT is only recoverable when supported by a valid, compliant invoice unless specifically excluded.
And a surprising number of invoices don’t meet the legal standards.
Common issues include:
- No VAT breakdown
- Missing VAT number (of the supplier)
- No invoice date
- No mention of your company name
- Vague or missing description of goods/services
- Use of till receipts or expense reports that don’t qualify
- Do not check if the VAT has been applies correctly
This is a classic error, especially for freelancers and SMEs — and tax authorities won’t hesitate to deny the deduction.
✅ How to avoid it:
- Implement an internal review process for all incoming invoices.
- For employee expenses, make sure to provide guidelines on acceptable formats.
- Use digital tools that flag non-compliant invoices automatically.
❌ Mistake #3: Reporting output VAT Too Late
This one is especially common in B2B environments.
Many businesses, regarding supply of services, assume they only owe VAT once the client pays — which is not always true. There are some particularities.
If you had applied for the VAT debit system, VAT is due as soon as the invoice is issued — regardless of whether the payment has been received or not.
This misunderstanding can cause:
- Late VAT payments
- Misalignment between accounting and tax records
- Potential penalties or interest in case of a control
✅ How to avoid it:
- Know which VAT regime your business is under.
- Identify the correct type of operation you’ve made to determine the good eligibility date.
✅ Good Practices to Keep You on Track
Here are some habits that will help you avoid VAT-related headaches:
📅 1. Monthly VAT Reconciliation
Regularly reviewing your VAT entries helps detect issues early — especially before report deadlines.
🧠 2. Train Your Team
Your accounting team — and anyone who handles invoices or expenses — should understand the basics of VAT compliance.
⚙️ 3. Use Automation
Modern accounting tools can flag risky entries, track deductible VAT, and help apply the right rates automatically. Leverage them.

VAT is a technical topic, yes — but it doesn’t have to be a nightmare.
By putting the right systems in place, you can stay compliant, avoid penalties, and even reclaim money you’re entitled to.
