Simplified vs Ordinary Accounting in Italy: Guide
For a sole proprietorship (ditta individuale) or partnership (società di persone) in Italy, choosing and managing the correct accounting regime is essential. Simplified accounting (contabilità semplificata) and ordinary accounting (contabilità ordinaria) are two distinct frameworks: they require different statutory records, different financial details, distinct rules for calculating taxable income, and different approaches to day-to-day document management.
This guide outlines the key differences between the two systems to provide practical clarity on obligations and compliance.
What Changes Between the Two Regimes
Ordinary accounting involves systematic, double-entry bookkeeping (partita doppia) covering all corporate transactions. Required statutory ledgers and registers record assets, liabilities, receivables, payables, cash flow, receipts, payments, and overall business performance.
Simplified accounting is designed for smaller businesses and is centered primarily on VAT registers, supplemented by the annotations required to determine taxable income under cash-based accounting rules. This does not mean casual record-keeping: even under simplified accounting, invoices, receipts, and tax documentation must be strictly organized and fully auditable.
Who Can Use Simplified Accounting
Generally, simplified accounting is available to sole proprietorships and partnerships whose annual revenue remains within statutory thresholds established by Italian tax law:
- Up to €500,000 for businesses primarily providing services.
- Up to €800,000 for businesses engaged in other activities (commerce, retail, production, etc.).
Eligibility cannot be determined by looking only at recent monthly revenue or personal projections. It requires proper identification of the business activity (ATECO code), the reference tax period, and applicable legal criteria. If revenue exceeds these limits, switching to ordinary accounting becomes mandatory.
Corporations, such as an SRL (società a responsabilità limitata), are required by law to maintain ordinary accounting regardless of their revenue volume.
Mandatory Records and Compliance: A Comparison
| Aspect | Simplified Accounting | Ordinary Accounting |
|---|---|---|
| Eligible Entities | Sole proprietorships and partnerships within statutory revenue thresholds | Corporations (SRL, SpA) and businesses exceeding limits or opting for the regime |
| Core Records | VAT registers integrated with required tax annotations for revenue/expenses | General journal (libro giornale), inventory ledger (libro inventari), VAT registers and ancillary records |
| Tracked Information | Transactions relevant for VAT and business income determination | Comprehensive recording of both economic results and financial balance sheet positions |
| Financial Outcome | Income calculated under applicable tax rules (cash basis or modified cash basis) | Full financial statements (bilancio d’esercizio) complying with civil code and tax standards |
This comparison provides a general overview. The exact statutory books and records required depend on the legal form of the entity, the specific economic sector, and current regulations.
Managing Documents Throughout the Year
High-quality bookkeeping relies on continuity and timely document collection. Postponing the delivery of paperwork until year-end makes reconciliation difficult and increases the risk of discrepancies.
It is best practice to systematically organize:
- Issued sales invoices and received purchase invoices.
- Electronic receipts (corrispettivi telematici) and summary reports, where applicable.
- Bank statements and documentation verifying business financial transactions.
- Invoices for professional services, operating expenses, and depreciable assets.
- Form F24 tax payment receipts and official Revenue Agency communications.
- Contracts, credit notes, and adjustments modifying recorded transactions.
All documents must be legible, linked to the appropriate fiscal period, and readily available in the event of a tax inspection.
Choosing the Accounting Regime: Beyond Apparent Simplicity
The right question is not which regime appears to require fewer administrative steps, but which regime fulfills statutory obligations and provides reliable financial data for the business.
Annual turnover, legal structure, growth plans, inventory management, capital investments, and relationships with banks and commercial partners are all vital considerations.
Up-to-date accounting allows business owners to evaluate financial performance, ensure timely VAT settlements, and prepare tax filings smoothly and accurately.
Common Mistakes to Avoid
- Confusing the tax regime (e.g. flat-rate forfettario vs ordinary) with the accounting regime (simplified vs ordinary).
- Assuming simplified accounting exempts a business from maintaining detailed records and supporting documents.
- Submitting incomplete documentation or records missing clear payment details.
- Failing to monitor cumulative annual turnover against statutory thresholds.
- Overlooking purchase invoices received outside the Italian SDI electronic invoicing system, such as foreign or intra-EU purchases requiring electronic self-invoices (autofattura).
- Mixing personal and business bank accounts without clear and reconcilable separation of transactions.
Frequently Asked Questions
Can I freely choose between ordinary and simplified accounting?
Not entirely. Adopting simplified accounting depends on your entity type and revenue thresholds. However, businesses that qualify for simplified accounting always have the option to voluntarily choose ordinary accounting, provided they maintain it for the statutory minimum period.
What happens if revenue exceeds the statutory limits?
Exceeding the statutory revenue limits requires transitioning to ordinary accounting starting from the following fiscal year (or as mandated by specific regulations). Monitoring turnover throughout the year ensures timely transition and compliance.
Are VAT registers sufficient on their own?
No. Under simplified accounting, VAT registers must be supplemented with records of cash receipts, disbursements, and non-VAT cost components. In ordinary accounting, double-entry ledgers, general journals, and inventory books are mandatory by law.
