## Common Corporate Forms
| Country | Popular Entity | Key Features | Tax Rate / Notes |
|---|---|---|---|
| **Argentina** | Sociedad Anónima (SA); Sociedad de Responsabilidad Limitada (SRL) | SAs are suitable for larger scale, SRLs for smaller businesses. Must deal with ARCA for invoices and digital tax versions. | Corporate income tax + profit presumption systems; certain digital invoicing compliance requirements (see RG 5852/2026) ([biblioteca.afip.gob.ar](https://biblioteca.afip.gob.ar/search/query/norma.aspx?p=t%3ARAG%7Cn%3A5852%7Co%3A9%7Ca%3A2026%7Cf%3A28%2F05%2F2026&utm_source=openai)) |
| **Peru** | Sociedad Anónima Cerrada; Sociedad Comercial de Responsabilidad Limitada | SARLs tend to have lighter governance, simpler shareholder structure. SAN creates more credibility. | Peruvian corporate income tax; SIRE obligations may apply; mandatory electronic records. ([cpe.sunat.gob.pe](https://cpe.sunat.gob.pe/node/141?utm_source=openai)) |

## Recent Regulation Highlights to Note
- In Argentina, **Resolución General 5852/2026** postpones to **1 August 2026** the enforcement of certain electronic billing (Comprobantes Electrónicos) rules and use of authorized electronic codes in contingency mode. ([biblioteca.afip.gob.ar](https://biblioteca.afip.gob.ar/search/query/norma.aspx?p=t%3ARAG%7Cn%3A5852%7Co%3A9%7Ca%3A2026%7Cf%3A28%2F05%2F2026&utm_source=openai))
- In Peru, SUNAT’s **Resolución de Superintendencia 0125-2026/SUNAT** gives taxpayers large and smaller delays to regularize electronic records and delay penalties through **31 August 2026**. ([cpe.sunat.gob.pe](https://cpe.sunat.gob.pe/node/141?utm_source=openai))

## Structuring Decisions & Comparison
- **Liability protection**: SRL or LLC types prevent personal liability more than sole trader setups.
- **Tax efficiency**: Argentine corporations can avoid retroactive proliferation of electronic rules if compliant (as per RG 5852/2026); Peru’s relief on penalties cushions switching costs.
- **Administrative burden & costs**: In Argentina digital invoice systems, ARCA constraints; in Peru, setting up books & records in SIRE takes time.

## Example Comparison
| Scenario | Argentina SRL vs Corte SA | Peru S.A.C. vs SRL |
|---|---|---|
| Small-scale web design business with two partners | SRL wins for simplicity and lower setup costs; careful use of invoices to meet electronic compliance – use CAEA only when needed. | SRL cleaner for custom work; minimize corporate overhead; monitor SIRE thresholds. |
| Export-oriented tech company | SA might attract better investor confidence; but must ensure electronic records tools are in place by 1 August 2026 to avoid penalties. | S.A.C. is often preferred; must integrate SIRE or equivalent electronic register asap. |
