Tax Due Diligence in Rome: Protecting the Value of the Investment
In every M&A transaction, tax due diligence is not a cost: it is an investment that protects the value of the deal. Latent tax risks can dramatically reduce the true value of an acquisition, generating liabilities that will only emerge years after completion — when the Italian Revenue Agency (Agenzia delle Entrate) begins audits of the years still open to assessment.
The Process: From Data Collection to the Executive Report
Our approach to tax due diligence follows a structured four-stage process:
- Scoping: defining the scope of the analysis based on the target's risk profile and the type of transaction;
- Data room review: reviewing tax documentation (returns, F24 forms, correspondence with the Italian Revenue Agency (Agenzia delle Entrate), relevant contracts) through access to a virtual data room;
- Management interview: a question-and-answer session with the target's CFO/tax manager to clarify the tax decisions taken and identify any aggressive tax positions;
- Report: an executive report with risk ratings (High/Medium/Low), quantification of potential liabilities and recommendations on contractual protection clauses.
Support in Negotiations: From the Report to Contractual Clauses
The added value of our team does not end with delivery of the report. We assist the buyer in negotiations to translate the risks identified into effective protection clauses: price adjustments, indemnity clauses, escrow agreements and security deposits. For targets with significant risks, we can structure plans to regularise their tax position before completion.
Tax Assessment Time Limits: The Time Horizon of Tax Risk
One of the most critical aspects of tax due diligence is determining the time horizon of the risk: how far back can the Italian Revenue Agency (Agenzia delle Entrate) raise tax challenges against the target company?art. 43 D.P.R. 600/1973 sets the statutory time limits for income tax assessments: the tax assessment notice must be served by 31 December of the fifth year following the year in which the return was filed (e.g. for the 2020 return, filed in 2021, the deadline expires on 31 December 2026). In the event of omessa dichiarazione, the time limit is extended to 7 anni. L'art. 57 D.P.R. 633/1972 provides for similar time limits for VAT. Crucially, where tax crimes are involved (fraudulent returns, issuing false invoices), the assessment time limits are raddoppiati: up to 10 years for filed returns and 14 years for unfiled returns. Thorough due diligence therefore examines at least the last 5 completed financial years (or 7 for more serious issues) and assesses whether there are any matters that could result in the time limits being doubled. As regards the entity's liability, D.Lgs. 231/2001 provides that the company is itself liable for tax crimes committed in its interests or for its benefit by its directors or employees: this liability passes to the buyer in the case of a share sale (but not in the case of a sale of a business division).
Employment Tax in Due Diligence: An Often Underestimated Area
Employment tax is one of the areas in which risks are most frequently identified during Italian tax due diligence, including for SMEs. artt. 23-30 del D.P.R. 600/1973 govern withholding tax on employment income and income treated as such: any error in the classification of income (e.g. incorrectly taxed fringe benefits, undocumented expense reimbursements, undeclared share options) results in a failure to withhold tax, with penalties starting at 20% and late-payment interest. Even more frequent is the issue of self-employed engagements reclassified as employment: if the Italian Revenue Agency (Agenzia delle Entrate) or INPS reclassifies consultancy contracts as employment relationships, the company faces liability for unpaid social security contributions (with civil penalties of up to 30% plus interest), failure to withhold personal income tax (IRPEF) and possible liability for failure to pay over withholding tax under art. 10-bis D.Lgs. 74/2000 where the thresholds for criminal liability are exceeded. The employment section of the tax due diligence report quantifies the exposure and recommends the remedial actions to be completed before completion.
Vendor Due Diligence: Enhancing Your Company's Value Before Sale
Vendor Due Diligence (VDD) is tax due diligence commissioned directly by the seller before starting the sale process. Its main advantage is the opportunity to identify and resolve tax issues in advance — regularising non-compliant positions, settling pending litigation and properly documenting tax credits — before they emerge during the buyer's due diligence and adversely affect the price. Well-conducted VDD also demonstrates the seller's commitment, shortens negotiations and minimises requests for protection (escrow, indemnities). The Firm manages the entire VDD process: from planning the scope of the analysis and preparing the report for prospective buyers to assisting with negotiations following the report.

Domande Frequenti — Tax Due Diligence
What Is Tax Due Diligence and When Is It Mandatory or Recommended?
+
Tax due diligence is a systematic analysis of a target company's tax position, aimed at identifying latent tax risks that could affect the value of the transaction or create future liabilities for the buyer. It is not required by law, but is strongly recommended for every M&A transaction, acquisition of a business division, introduction of significant new shareholders or recapitalisation. Omitting due diligence means acquiring unknown tax risks: tax years still open to audit, non-existent tax credits and pending litigation not disclosed in the financial statements.
How Long Does Tax Due Diligence Take and How Is It Conducted?
+
The time required depends on the size and complexity of the target company. For an Italian SME, standard tax due diligence takes 2–4 weeks. For groups with complex structures or international operations, this increases to 4–8 weeks. The process comprises: collecting documentation (tax returns for the last 5 years, correspondence with the Italian Revenue Agency (Agenzia delle Entrate), relevant contracts), a desk-based review by the team, a site visit with the target's management, and preparation of a report identifying risks and quantifying potential liabilities.
What Are the Most Common Tax Risks Identified During Due Diligence?
+
The most frequently identified risks concern: improper use of undocumented tax credits or tax credits to which the company is not entitled (R&D, Patent Box, ZES); undocumented transfer pricing between group companies; VAT on incorrectly classified cross-border transactions; failure to tax capital gains on disposals of shareholdings; failure to pay over withholding tax on fees paid to consultants; the possibility of challenges to corporate reorganisations for lack of 'valid economic reasons'; and tax payment notices (cartella) that have not been appealed. The due diligence report quantifies potential liabilities and suggests contractual protection clauses (escrow, indemnities, price adjustments).
Who Should Bear the Cost of Due Diligence, the Buyer or the Seller?
+
The cost of tax due diligence is typically borne by the buyer, who commissions the analysis to protect their investment. The seller may, however, arrange Vendor Due Diligence (VDD) in advance — commissioning independent due diligence on their own company — to accelerate negotiations, demonstrate transparency and secure a higher valuation. In some transactions (competitive auctions, structured sale processes), VDD is almost mandatory. The Firm, Marzo Associati, handles both types.
