1. Il problema in parole semplici
In recent years, the Italian Revenue Agency has intensified tax audits on flat-rate VAT numbers, particularly targeting cases where revenues exceed the permitted thresholds. In practice, they’ve examined bank accounts, wire transfers, prepaid cards, and assets to reconstruct actual earnings. Those who exceeded the €65,000 annual threshold risk being deemed non-compliant. We’re talking about individuals who, in 2021, earned as much as €90,000 but continued operating under the flat-rate regime in 2022.
One-off cases, such as insurance payouts or occasional winnings, are excluded if the taxpayer can demonstrate consistent income—for example, at least €80,000 in 2022 as well. This way, the Agency distinguishes between exceptions and actual abuses.
2. What Being Under Audit Entails: The Consequences
The risks for taxpayers are twofold:
- Taxes to Pay: Moving from the flat-rate regime (fixed, simplified substitute tax) to the ordinary regime, with progressive IRPEF, additional regional/municipal taxes, and potentially IRAP and IRES.
- Penalties and Interest: Beyond unpaid taxes, fines and late-payment interest apply.
- Additionally, obligations previously suspended are reinstated: VAT accounting, ordinary bookkeeping, and periodic tax filings—a significant burden to manage.
3. Why These Tax Audits on Flat-Rate VAT Numbers Are Happening Now
The Revenue Agency uses increasingly sophisticated IT systems to cross-reference data: bank transactions, cadastral records, financial movements, and electronic invoices. It’s no longer possible to hide actual revenues behind apparent formal compliance. These systematic checks aim to identify those who have improperly benefited from the flat-rate regime, focusing on those who remained in the regime despite exceeding the thresholds.
4. Summary Table: Key Dates and Deadlines
| Date | Action |
| 2021 | Check if revenues exceeded €65,000. |
| End 2022 | Verify consistent high revenues (e.g., €80,000 or more). |
| 2023 | Note: Exceeding limits in 2021 means exiting the flat-rate regime. |
| Current Year | Potential audits and disputes from the Revenue Agency. |
| Immediate | Contact us for preliminary checks and regularization assistance. |

8. Differences Between Flat-Rate and Ordinary Tax Regimes: What Really Changes
Understanding the distinction between the flat-rate and ordinary tax regimes is crucial, especially to grasp the implications of transitioning due to tax audits on flat-rate VAT numbers.
The flat-rate regime is designed to simplify life for professionals and micro-businesses. Key features include:
- Fixed 15% tax rate (reduced to 5% for the first 5 years in some cases).
- No VAT obligations, ordinary bookkeeping, or VAT registers.
- No withholding taxes.
- Reduced bureaucracy, costs, and administrative time.
Switching to the ordinary regime changes everything:
- Progressive IRPEF rates (23% to 43%).
- Mandatory VAT filings, bookkeeping, and ordinary accounting.
- Increased tax and reporting obligations.
- Withholding taxes, sector studies, and more frequent cross-checks.
This shift, often triggered by tax audits on flat-rate VAT numbers, impacts not only taxes owed but also work organization.
9. Common Mistakes to Avoid in the Flat-Rate Regime
Many professionals, often in good faith, make mistakes that can trigger tax audits on flat-rate VAT numbers. Common errors include:
- Exceeding the €65,000 threshold unknowingly due to poor invoice tracking.
- Including non-taxable income (e.g., personal loans or family transfers) that the Revenue Agency may interpret as revenue.
- Running multiple activities (e.g., freelancing and e-commerce) without properly consolidating revenues.
- Failing to switch to the ordinary regime promptly after exceeding the limit in the previous year.
- Using prepaid cards or non-personal accounts for professional payments, complicating proof of income sources.
These mistakes, if not addressed promptly, can lead to complex and costly consequences.
10. What the Revenue Agency Actually Checks
During tax audits on flat-rate VAT numbers, the Revenue Agency doesn’t just review tax returns. They use:
- Access to bank accounts and all transactions.
- Analysis of incoming and outgoing wire transfers.
- Examination of credit cards, prepaid cards, and digital wallets.
- Assessment of overall assets, including real estate, vehicles, and insurance policies.
- Cross-referencing with electronic invoices, personal income declarations, and CU forms.
This means even careless financial management can trigger an audit, even without intentional violations.

12. Be Aware: Thresholds May Change, Stay Updated
The flat-rate regime thresholds can change based on Budget Laws. For instance:
- Since 2023, the threshold increased to €85,000 for some categories.
- However, exit rules remain: exceeding the threshold in year “N” means leaving the regime in year “N+1.”
Staying updated is crucial, and we can help. Don’t rely on hearsay or unverified online information—Italian tax rules are too complex to leave to chance.
