Tax advisory for businesses: complete guide 2026
Tax management is one of the most critical — and often most underestimated — aspects of running a business. A mistake in a tax return, a late VAT payment, or a poor choice of company structure can have significant financial consequences.
Why businesses need professional tax advisory
The Italian tax system is among the most complex in the world: hundreds of annual compliance obligations, continuously evolving regulations, and significant differences between tax regimes. Businesses that rely on expert tax advisers:
- Reduce their tax burden through legitimate optimisation tools
- Avoid penalties that can reach 200% of the unpaid tax
- Free up time to focus on core business
- Plan better for investments and profit distribution
Tax advisory services for businesses
Standard and simplified bookkeeping
The choice between standard and simplified bookkeeping depends on turnover and company structure. Companies incorporated as Srl or SpA always use the standard regime. Partnerships and sole traders can opt for the simplified regime if revenue does not exceed €500,000 (services) or €800,000 (goods).
Standard regime includes:
- Day book, ledger, inventory records
- VAT purchase and sales registers
- Depreciable asset register
- Annual financial statements with explanatory notes
Simplified regime requires:
- VAT registers
- Cash receipts and payments register (since 2019)
- No statutory financial statements
Corporate VAT management
VAT is one of the most frequent and error-prone obligations:
- Monthly or quarterly settlements based on turnover
- Quarterly VAT settlement communications (LIPE)
- Annual VAT return by April
- Esterometro — self-invoice for intra-Community purchases of goods and services and extra-Community purchases of services; submission of Intrastat forms for intra-Community supplies of goods and services
- Mandatory electronic invoicing via the SDI interchange system
Tax planning and optimisation
A corporate tax adviser does more than compliance: they plan. This includes:
- Optimal choice of company structure (Srl vs. partnership vs. sole trader)
- Timing investments to maximise deductions
- Use of tax credits (e.g. R&D credit, Industry 4.0 training credit)
- Planning profit distributions
- Managing tax losses
Corporate income tax return (UNICO SC)
The annual income tax return for incorporated companies is a complex document that requires:
- Calculation of IRES (corporate income tax, rate: 24%)
- Calculation of IRAP (regional production tax, base rate: 3.9%, variable by region)
- Managing upward and downward adjustments
- Completion of the state aid schedule
How to choose the tax adviser for your business
The key criteria are:
- Experience in your specific sector (retail, services, manufacturing, etc.)
- Structured team capable of handling peak workloads (tax deadlines)
- Digital tools for document exchange and remote signing
- Proactivity in informing you of applicable tax incentives
- Integrated approach covering tax, employment law and corporate matters
