The moment of company registration is the first major milestone for many entrepreneurs. However, the work is just beginning: in the first 30 days, there are several administrative and financial tasks that, if neglected, could lead to fines, suspension, or operational difficulties.

In this guide, we walk through what needs to be accomplished in the first month after company formation and show you how we help ensure everything goes smoothly and error-free.

1. Checking the company extract and tax number

Once the Company Registry Office has registered the company, the business automatically receives a company registration number and tax number.

This is the first document to request and verify to ensure:

all data is accurately recorded (registered office, activity, executive, etc.),

the tax number is active,

and the company is listed in the register.

Incorrect or incomplete data can later cause problems with invoicing, opening a bank account, and even during tax inspections.

2. Opening a corporate bank account

For s and s, having a corporate bank account is mandatory, which must be opened within 8 days following registration.

It's important that:

the account is in the company's name,

all documents (articles of association, company extract, signature specimen) are presented to the bank,

and the bank account must also be reported to .

We assist throughout the entire process – even in online account opening – to ensure this step proceeds quickly and without administrative hassle.

3. Starting bookkeeping and notifications to

The most important task in the first 30 days after company formation is setting up the accounting system. In the first month, it is necessary to:

establish general ledger accounts,

set the tax form (KIVA, TAO, etc.),

make contributions and notifications,

and schedule the first reporting periods.

Failing to notify can result in fines, so it’s recommended to involve the accountant from the day of founding.

4. Billing system and connection with

The company must use an invoicing program, which must also be reported to . Connecting the invoicing system to the system is mandatory, especially if the business is subject to .

We assist in:

selecting the appropriate invoicing system (e.g., online, automated system),

setting up the connection,

and checking the invoicing processes in the first month.

5. Contract templates, client documents, and General Terms and Conditions

Many businesses forget that after company formation the related contracts and regulations must also be arranged:

commission contracts,

framework agreements for business partners,

privacy statement (),

general terms and conditions ().

These not only provide legal protection but also convey professionalism and reliability to partners.

6. Announcements to the local government – (local business tax)

Announcing the local business tax is mandatory within 30 days, even if the company has not yet conducted any active business. This must be done in the municipality's electronic system, and late announcements may result in surcharges or fines.

We automatically handle announcements for all our clients, eliminating the need for separate administration.

7. Employee registration and payroll initiation

If the company employs workers from the start, they must be registered with in the first 30 days, and payroll processes need to be initiated.

We comprehensively manage:

employee registration,

defining contribution payment obligations,

monthly payroll and declarations.

This ensures that from the very beginning the company meets all legal and administrative requirements.

8. Company email, website, and official communication

Following company registration, it is advisable to establish official contacts:

company email address (e.g., info@.hu),

website,

electronic client portal and company portal registration.

The company portal is the official communication channel – through which notifications from and authorities are received. We assist every client with the setup and initial login.

9. Launching marketing and invoicing

A successful start requires more than a legal background – the company's operations must also be initiated on both financial and marketing levels.

Developing pricing and invoicing structures

Preparing client contracts

Online presence (domain, social profiles)

Cash flow and cost planning for the first month

We also provide support in these areas to ensure that the start is not only legal but also business-wise stable.

10. Conclusion – the first 30 days are the key to success

The first month is crucial in the life of every business. Those who build a system at this time will save time, money, and stress later. However, those who procrastinate may easily encounter deadlines, incomplete notifications, and fines.

We not only help launch the company but also oversee every step of the first 30 days – so the business can start its path to growth safely and calmly.
