Using a facsimile signature (a stamp) is a common business practice designed to speed up document workflows. These signatures are most frequently used for contracts, statements of work, invoices, and other primary source documents. However, the legal framework for this tool in Russia is fragmented. Judicial and tax practice shows that the Federal Tax Service of Russia pays close attention to its use, creating significant risks ranging from disputes with counterparties to the denial of tax deductions and the imposition of tax penalties, including additional tax assessments, fines, and interest.
Legal Regulation of Facsimile Signatures
The use of a facsimile signature is permitted in cases and in the manner provided for by law, other legal acts, or an agreement between the parties (Clause 2, Article 160 of the Civil Code of the Russian Federation).
Although legislation does not explicitly authorize the use of facsimile signatures in contracts and other documents with counterparties, judicial practice holds that they are permissible provided there is an express agreement between the parties (Resolution of the Arbitration Court of the Central District dated January 19, 2022, No. F10-6305/21).
At the same time, there are a number of documents where the use of a facsimile signature is prohibited. These include powers of attorney, payment documents, and other instruments with financial implications (Letter of the Ministry of Taxes and Duties of the Russian Federation dated April 1, 2004, No. 18-0-09/000042; Appellate Ruling of the Moscow City Court dated November 26, 2025, in Case No. 33-30934/2025), as well as documents related to state and municipal procurement (Letter of the Ministry of Economic Development of the Russian Federation dated June 11, 2010, No. D22-839).
However, judicial practice considers the following documents eligible for signature in this manner:
- contracts and supplementary agreements (provided the parties have agreed to the use of a facsimile signature);
- insurance and medical policies;
- letters of appreciation, certificates of honor, and awards for work or academic achievements;
- invitations, notices, and notifications;
- official identification cards;
- patents;
- internal organizational documents: reports, letters, etc.
Key Risks
The use of a facsimile signature involves not only formal restrictions but also significant legal consequences.
1. Tax Risks:
- Invoices signed with a facsimile do not entitle a taxpayer to a VAT deduction (Ruling of the Supreme Court of the Russian Federation dated July 16, 2021, No. 307-ES21-10502; Resolution of the Presidium of the Supreme Arbitration Court of the Russian Federation dated September 27, 2001, No. 4134/11);
- Corporate income tax expenses supported by documents with a facsimile signature may be disallowed and excluded from the tax base (Letter of the Ministry of Finance of the Russian Federation dated June 10, 2021, No. 03-11-11/45946);
- Additional tax assessments, fines, and interest may be imposed because the Federal Tax Service of Russia may deem documents signed with a facsimile as not having been submitted at all.
Such violations are typically identified during desk or field audits.
2. Risk of documents being deemed unsigned:
If the use of a facsimile signature has not been agreed upon by the parties in advance, there is a risk of:
- the contract or supplementary agreement being deemed unconcluded, which may make it impossible to collect payment for the transaction, lead to the classification of received funds as unjust enrichment, and necessitate the re-execution of documents;
- subsequent corporate disputes (for example, if the CEO contests their consent to the signing of the document), which often require significant time and financial resources.
However, the mere use of a facsimile does not automatically invalidate a transaction if it has been performed in practice, provided that neither party initiates a dispute (Resolution of the Arbitration Court of the East Siberian District dated February 3, 2022, in case No. A58-7571/2020).
3. Risk of automatic acceptance of work/services:
Contracts often include a provision stating that if the client fails to sign an acceptance certificate within a specified period, the certificate is deemed signed and the work/services accepted. Using a facsimile to sign such a certificate can lead to the following consequences:
- increased risk of unauthorized use of the facsimile by staff or third parties, which may result in certificates being signed without actual verification of the work;
- in the absence of timely objections from the client, the automatic acceptance clause triggers an obligation to pay.
4. Evidentiary risks:
Courts may refuse to recognize documents signed with a facsimile as admissible evidence if the parties have not explicitly authorized the use of a signature stamp (Resolution of the Ninth Arbitration Court of Appeal dated April 1, 2024, No. 09AP-6394/24 in case No. A40-174330/2022).
C Cases Recommendations
Given current legal practice, the use of a facsimile requires proper legal regulation within both contractual and internal documentation. The C Cases team recommends:
- explicitly authorizing the use of a facsimile in the contract or a separate agreement;
- defining an exhaustive list of documents where a facsimile is permitted, while excluding documents with financial implications (certificates, invoices, payment documents);
- avoiding the use of a facsimile on documents intended for submission to the Federal Tax Service of Russia;
- ensure access control for the signature stamp and establish internal usage protocols;
- prioritize handwritten signatures or qualified electronic signatures for significant transactions and contentious situations;
- account for the risk that documents may not be accepted as evidence when building a case for court.
Conclusion
A facsimile signature can be used in civil commerce as a tool to streamline document workflows; however, its use is only permissible when established restrictions are observed and a direct agreement between the parties is in place. Current judicial and tax practice shows heightened scrutiny toward such documents and, consequently, an increased level of associated risk. In the absence of proper contractual documentation and internal controls, the use of a facsimile can lead to negative legal consequences, including tax assessments, difficulties in providing evidence, and the emergence of disputed obligations.
