Buying and Selling Shares in an SA in Uruguay: Process, Contract and Taxes
Buying and selling shares in a corporation (SA) in Uruguay is one of the most important corporate transactions for both local and foreign investors. Whether because a shareholder is leaving, a new strategic partner is joining or the entire shareholding is being sold, transferring shares in an SA involves following a specific legal procedure, with well-defined registry, tax and documentary obligations.
In this guide we explain step by step how the transfer of shares in a Uruguayan SA works, which documents are involved, which taxes apply and the critical points every buyer and seller should know before closing the deal.
Registered Shares in Uruguay: The Mandatory Starting Point
Before looking at the transfer process, it is essential to understand the legal framework governing shares in Uruguay. Since the entry into force of Law No. 18,930 and its amendments, all shares issued by Uruguayan corporations must be registered (nominative). This means each share has an identified owner, whose name appears both on the certificate and in the company’s register.
Registered shares in Uruguay cannot be transferred anonymously or simply by handing over the certificate. Every transfer must be recorded in the company’s share register and formally notified to the company. The purpose of this requirement is transparency in identifying companies’ beneficial owners, in line with international anti-money laundering standards.
A direct consequence of this regime is that the buyer only becomes a shareholder vis-à-vis the company once the transfer has been recorded in the relevant register, regardless of whether the purchase agreement has been signed.
Restrictions on Transferring Shares in a Uruguayan SA
Unlike the quotas of an SRL, the shares of an SA are in principle more freely transferable. However, there are restrictions on transferring shares in a Uruguayan SA that may arise from the law or from the bylaws themselves:
- Restrictions in the bylaws: the bylaws may limit the free transferability of shares, for example by requiring prior approval from the board of directors or the shareholders’ meeting to admit a new shareholder.
- Pre-emption or first-refusal rights: the bylaws may provide that, before selling to a third party, the selling shareholder must offer the shares to the other shareholders on the same terms.
- Lock-up clauses: in shareholder agreements linked to investments or financing, there may be a period during which shareholders cannot transfer their shares without authorisation.
- Sector-specific legal restrictions: in certain regulated activities (financial, healthcare, public concessions, etc.), transferring shares may require prior approval from a regulator.
- Injunctions or attachments: if the shares are subject to a court order, their transfer may be blocked until the order is lifted.
Reviewing the bylaws and any shareholder agreement in force is the essential first step before starting any sale.
How to Sell Shares in an SA in Uruguay: The Process
The process of selling shares in an SA in Uruguay can be summarised in the following stages:
- Preliminary review: analysing the bylaws, checking for restrictions, reviewing shareholder agreements and assessing the seller’s tax situation.
- Complying with restrictions: if the bylaws provide for pre-emption rights or other mechanisms, these must be complied with before selling to a third party.
- Negotiating and setting the price: agreement between the parties on the value of the shares (see the dedicated section below).
- Signing the share purchase agreement: the legal instrument documenting the transaction with all its terms and conditions.
- Notary involvement: certification of signatures or execution of a deed, as required by the bylaws or the parties.
- Updating the share register: recording the transfer in the relevant corporate book, signed by the company’s representative.
- Paying taxes: determining and paying any taxes due on the gain obtained.
- Updates with government agencies: DGI, the BCU (beneficial owner declaration) and others as applicable to the activity.
The Share Purchase Agreement in Uruguay
The share purchase agreement in Uruguay is the core document of the transaction. Unlike the assignment of quotas in an SRL — which requires a public deed — the transfer of shares in an SA can be documented in a private document with signatures certified by a notary, unless the bylaws require a public deed or the parties so agree.
The agreement should contain at least:
- Full identification of the seller (transferor) and the buyer (transferee).
- Identification of the company issuing the shares: name, RUT (tax ID), registration details.
- Description of the shares being transferred: number, class, numbering where applicable, and the percentage of total capital they represent.
- The price and payment terms: method, currency, timing and any guarantees.
- The seller’s representations and warranties: that the shares are freely transferable, not encumbered or attached, and that there are no significant hidden liabilities, among others.
- Conditions precedent, if any: regulatory approvals, lifting of restrictions in the bylaws, etc.
- The closing date and the date on which ownership of the shares is effectively transferred.
- Post-closing liability and any price adjustments.
In larger or more complex transactions, the share purchase agreement is usually preceded by due diligence and may include price adjustment clauses based on net assets at closing, escrow mechanisms and more extensive representations.
The Notary’s Role in Buying and Selling Shares in a Uruguayan SA
The notary (escribano) in the purchase and sale of shares in a Uruguayan SA plays an important role, although it is not always strictly mandatory. Their main functions in this type of transaction are:
- Certifying signatures: the notary certifies that the seller’s and buyer’s signatures are authentic, giving the private document greater legal certainty.
- Executing a deed: when the parties or the bylaws so require, the transaction is formalised by public deed, which gives it a certain date and immediate enforceability.
- Checking documents: the notary verifies the identity of the parties, reviews the corporate documents and checks that there are no formal obstacles to the transfer.
- Involvement in the share register: in many cases, the notary also takes part in recording the transfer in the share register, giving the act greater formality.
- Tax withholding: when tax must be withheld from the seller (for example, IRNR for non-residents), the notary may act as withholding agent.
Having a notary involved in the transaction, even when not legally required, is good practice that reduces the risk of challenges and makes it easier to prove the transaction to third parties.
The Share Register of an SA in Uruguay
As mentioned at the start, the share register of a Uruguayan SA is the instrument that determines who is a shareholder vis-à-vis the company. Unless it is updated, the transfer of shares has no effect on the company or third parties.
The entry in the register should include:
- The date of the transfer.
- The name and identification of the seller and the buyer.
- The number and numbering of the shares transferred.
- The price or declared value of the transaction.
- The signature of the company’s authorised representative certifying the entry.
Once the entry is made, the buyer can request that the share certificate be endorsed in their name or that a new share certificate be issued, depending on the company’s practice.
The share register is also the primary source for the beneficial owner declarations the company must file with the BCU, so updating it correctly has regulatory implications that go beyond the internal relationship between shareholders.
Taxes on Buying and Selling Shares in a Uruguayan SA
The taxes applicable to buying and selling shares in an SA in Uruguay depend mainly on the seller’s tax residence and whether there is a taxable capital gain. The main taxes to consider are:
- IRPF (personal income tax): if the seller is an individual tax resident in Uruguay, the gain on the sale of shares (the difference between the sale price and the adjusted tax cost) is taxed as a capital gain at 12%.
- IRNR (non-residents’ income tax): if the seller is an individual or legal entity not resident in Uruguay, the Uruguayan-source gain is subject to IRNR. The general rate is 12%, and the buyer must withhold it when the buyer is a Uruguayan resident.
- IRAE (corporate income tax): if the seller is a company subject to IRAE, the gain on the sale of shares is added to its taxable income at 25%.
- ITP (property transfer tax): whether it applies to a transfer of shares must be analysed case by case with a tax adviser, as its scope may vary depending on the nature of the company’s underlying assets.
- VAT: in principle it does not apply to a simple sale of shares, although specific situations may require analysis.
Tax planning before the transaction is especially important when there are significant capital gains, when non-residents are involved or when the company has significant real estate assets that may lead to different tax treatment.
How to Set the Price of Shares in a Uruguayan SA
Setting the price of shares in a Uruguayan SA is one of the most complex aspects of a sale, especially when the company is not listed and there is no market reference price. The most common methods in practice are:
- Book value: the price is calculated in proportion to the company’s net book value according to its latest audited financial statements. It is the simplest method but does not necessarily reflect the real value of the business.
- Adjusted book value: starts from net book value but adjusts certain items to market value: revalued real estate, unrecorded intangible assets, contingent liabilities, etc.
- Discounted cash flow (DCF): a more sophisticated method that projects the company’s future cash flows and discounts them at a rate reflecting the business risk. It is the standard in larger or more complex transactions.
- Market multiples: multiples of EBITDA, sales or other indicators of comparable companies in the same sector are applied to estimate the value.
- Free agreement between the parties: in many cases, especially in small and medium-sized companies, the price simply results from direct negotiation between seller and buyer, without formal valuation methods.
Whatever the method, it is advisable for the agreed price to be documented and justified in the agreement, especially for tax purposes: DGI may challenge prices that deviate significantly from real market value in transactions between related parties.
Conclusion
Buying and selling shares in an SA in Uruguay is a transaction well structured by local company law, but it requires attention to many aspects: checking restrictions in the bylaws, documenting the agreement correctly, involving a notary where appropriate, updating the share register and paying the applicable taxes properly.
Both the seller and the buyer benefit from specialist legal, notarial and accounting advice from the start of the process. A well-structured transaction protects both parties, guarantees the validity of the transfer and avoids future tax or legal contingencies.
