Starting a business here can be difficult and not necessarily profitable. You need to speak Spanish I would think. I would contact an immigration lawyer here to find out if you need the monthly income that retirees need to show or not.
Here is a little info I found on starting a business here.
All businesses must register with certain government entities:
DGI, or “Dirección General Impositiva”, the tax authority
BPS, or “Banco de Prevision Social”, the social security administration
BSE, or “Banco de Seguros del Estado”, the government insurance agency: for mandatory employee insurance.
MT, or “Ministerio de Trabajo”, the Labor Ministry which issues the Employee Roster that must be kept in the company, with a full list of employees, position, wage, and work schedule
Salaries must be in line with minimum wages and increases of each worker category. There are set wages for each type of job here and numerous paid days, holiday pay etc in addition to the hourly wage.
Workers are granted the right to severance pay of one monthÂ’s salary for each year or fraction of a year worked, with a cap of six months.
Maximum work hours: Commercial and services activity: 44 weekly hours, Industrial activity: 48 weekly hours.
All workers must be registered with the BPS
Social Security:
EmployerÂ’s contribution for each worker's social security and other work-related taxes are
12.6% EmployeeÂ’s social security and other work related taxes: 18.1% plus they also pay personal Income Tax (0-25%)
Corporate Income Tax, or “IRAE” - 25% of net profits
Asset Tax, or “IP” - 1.5% of fiscal value of assets (deductibility of liabilities can effectively reduce the rate to half)
Capital Gains Tax - 25% of net gain on value of assets
IVA, or “Value Added Tax” - the consumer pays 22% for most products; 10% for some, 0% for a short list
Many businesses in my area tend to be seasonal and close from Easter until the beginning of December.
