Advisory support for opening a business in 2026: key procedures
You already have the idea. Now comes the part that usually raises the most questions: everything that needs to be done before getting started.
Paperwork, registrations, taxes, permits, legal decisions… Opening a business in 2026 involves several steps that should be well organised from the beginning to avoid mistakes that may later cost time and money.
The good news is that, with proper planning and the right advisory support, the whole process can be much simpler than it seems.
First: do not start with the paperwork
Many people make the same mistake: they begin filling in forms without having clearly defined how the business will operate.
Before registering, it is important to clarify a few points:
● What you are going to sell or what service you will offer.
● Who your target clients are.
● How you are going to invoice.
● Whether you will work alone or with partners.
● Whether you will need premises, employees, or initial investment.
● What monthly expenses you will have.
Having this foundation clear will help you make better tax and legal decisions later.
The procedures you need to start
Registering correctly
One of the first steps is to register with the Tax Agency and Social Security.
This defines:
● Your economic activity.
● Your tax regime.
● Your tax obligations.
● Your status as self-employed or as a company.
Although it may seem like a simple procedure, making the wrong choice can affect the taxes you will pay or how you will need to manage your activity in the future.
Choosing between self-employed status and a company
This is one of the most important decisions when opening a business.
Working as self-employed is usually quicker and easier when starting out. However, creating a limited company may provide greater protection and advantages in certain cases.
It all depends on factors such as:
● Expected income level.
● Initial investment.
● Risk level of the activity.
● Whether there are several partners.
● Growth plans.
Reviewing permits and licences
Some businesses can start quickly, while others require specific authorisations before opening.
For example:
● Opening licence.
● Health permits.
● Trademark registration.
● Data protection.
● Mandatory insurance.
● Municipal licences.
This point is often underestimated and can delay the start of the activity if it is not reviewed in time.
What almost nobody tells you when opening a business
Opening a company is not just about “doing paperwork”. It also means properly organising the financial and administrative side from day one.
For example, it is advisable to:
● Separate personal and professional accounts.
● Keep fixed expenses under control.
● Prepare an invoicing system.
● Review contracts before signing them.
● Plan quarterly taxes.
● Properly store invoices and documentation.
Small details like these make a major difference when the business starts to grow.
Mistakes that can complicate the start
Many problems arise from trying to do everything too quickly or without professional advice.
Some common mistakes include:
● Choosing the wrong activity heading.
● Miscalculating taxes.
● Starting without the necessary permits.
● Using generic contracts.
● Not reviewing legal obligations.
● Failing to forecast the real expenses of the business.
Most of these mistakes can be easily avoided with good initial planning.
