You first step is visiting this place (all must be done online):
onapi oficina nacional de la propiedad industrial
There you can read up on what you’ll need to setup your business name. Then create an account to register your company name and any commercial distinctive like logo, etc
The whole process will take about three weeks and you can pay online as well via the bank.
After you get your Commercial name a marks registered, you need to create the business with a legalized notary letter to the effect. They offer samples of these there as well.
Also need to open a commercial account in the bank with the Onapi registration and copies of the pending registration to Cámara del Comercio.
Just write pending on the RNC section fir these steps. After you get the documents to Cámara del Comercio and your registration is carried out, that’s when you apply for the RNC.
That’s pretty much all there’s to it.
Keep in mind most if not all (notary not included) of the steps will be carried online for the most part. Some minor visits after submitting the paperwork online will be required.
Onapi alone is about 5k depending on marks and business type. Could be more.
It’s pretty straightforward if you are familiar with legal DR Spanish terms on forms.
You can save time and hassle by paying a firm to carry it all for you. It will be more expensive but worth it at the end.
