The consolidated code on tax obligations and assessment, annexed to D.Lgs 5 August 2026, no. 141, reorganises filing rules and tax controls. The decree entered into force on 7 August 2026, while article 368 makes the annexed code’s provisions applicable from 1 January 2027. These are different dates.

Publication and application dates

The decree was published in Gazzetta Ufficiale no. 181 of 6 August 2026, ordinary supplement no. 28. The annex contains 368 articles. Saying that the entire decree enters into force only in 2027 confuses its commencement with the code’s application date.

For a specific obligation, also read the coordinating provisions, repeals and the timing of each amendment.

Reorganisation does not mean every rule is unchanged

The code brings together filing obligations, administrative powers, assessment and final provisions previously spread across legislation. This makes related rules easier to locate.

The decree also contains coordinating and corrective amendments. Do not assume that every change merely renumbers existing articles: check the affected provision.

Articles 159 and 161: powers and inspections

Article 159 covers tax-office powers, including financial-information requests. Article 161 concerns access, inspections and audits, bringing together familiar direct-tax and VAT provisions.

These powers retain conditions and safeguards. The bank-account tax inspection guide distinguishes presumptions about transactions from authorisation requirements.

Review references before 2027

Advisers and businesses can review procedure templates, software and legislative references. This is practical maintenance, not a universal obligation to rewrite every contract by 1 January.

Article 367 also redirects references to repealed provisions to corresponding code provisions. An old reference does not automatically invalidate a document.

Use the official text for the applicable rule

The sources below link to the official decree and the application and repeal articles. Check the current text and subsequent updates for the obligation concerned.

The October 2026 tax calendar remains relevant to current returns. The code’s 2027 application does not by itself move 2026 deadlines or change payroll IRPEF rates.
