Keep your Chilean entity's domicilio tributario verifiable by the SII and its comuna-level domicilio social current with the Conservador de Comercio, so a routine move never leaves the inicio de actividades observado.

Primary Registry
SII
A Chilean entity's domicilio social is set at the comuna level in its bylaws, while its domicilio tributario is the exact street address declared to the SII at inicio de actividades, and a separate domicilio comercial covers where operations actually happen, need not match either exactly but must stay coherent and documented. A virtual office or coworking address is accepted only when the declared economic activity can genuinely be performed there, professional services, digital agencies, and e-commerce without inventory qualify, while retail with foot traffic, restaurants, personal services, manufacturing, and warehousing do not. Since Circular N°38 of 2025, any address declaration requires full detail, calle, número, comuna, ciudad, región, plus the occupancy arrangement, rental, comodato, or usufruct, and the owner's RUT if the entity isn't the owner. The SII can conduct a physical verification visit at inicio de actividades or after any address change, and a simple lease without legalized signatures or a rent receipt without an underlying contract leaves the process observado, with the RUT inactive and electronic invoicing blocked, until a legalized lease or notarized comodato is on file. A street-level move is filed through Form 3239 within 15 business days, while a move to a different comuna instead requires a notarized deed amendment, inscription at the Conservador de Comercio, and Diario Oficial publication within 60 days, a 2 to 3 week process for traditionally-formed companies, though the same change is instant and fully digital for an Empresa en un Día SpA.
Domicilio tributario, the exact street address declared to the SII at inicio de actividades, kept legally distinct from the comuna-level domicilio social in the bylaws and the operational domicilio comercial
Virtual office or coworking address accepted only when the declared economic activity can genuinely be performed there, professional services and digital businesses qualify, retail with foot traffic, restaurants, and manufacturing do not
Full address detail, calle, número, comuna, ciudad, región, plus the occupancy arrangement and the owner's RUT if the entity isn't the owner, required under Circular N°38 (2025) for any address declaration
SII physical verification visit possible at inicio de actividades or after any address change, leaving the process observado and the RUT inactive until a legalized lease or notarized comodato is on file
Form 3239 filed within 15 business days for a street-level move; a change of comuna instead requires a notarized deed, Conservador de Comercio inscription, and Diario Oficial publication within 60 days
Many assume any address change is the same simple Form 3239 filing. Moving to a different comuna instead triggers the full escritura-amendment path through the Conservador de Comercio and Diario Oficial, a materially slower and more expensive process.
A simple lease without legalized signatures, or a rent receipt without an underlying contract, is not sufficient documentation. The SII's field visit can leave the inicio de actividades observado and block electronic invoicing until the paperwork is cured.
The same address change that's instant and fully digital for an Empresa en un Día SpA requires a notary, a public deed, and Diario Oficial publication for a traditionally-incorporated company, a distinction that trips up owners who don't know which structure they have.
Assessment of whether the declared address and economic activity combination will pass the SII's compatibility screen before inicio de actividades is filed
Preparation of a legalized lease or notarized comodato sufficient to satisfy an SII field visit, avoiding an observado status that blocks invoicing
Form 3239 filing within the 15-business-day window for street-level address changes
