Overview of tax and contribution changes for entrepreneurs in 2026

Every year brings a host of changes to the business environment, and the new year is no exception. If you follow changes to the law only in passing, it is easy to be caught out by an obligation that you only discover when filing your tax return or during an inspection. This overview will help you get your bearings on which areas are amended most often and what to watch out for, without getting lost in the sections of the legislation.

Why it pays to keep up with changes to the law

Tax and contribution legislation is among the most frequently amended areas of Slovak law. It responds to the state budget, to court decisions and to European directives. Specific amounts, rates and thresholds can therefore shift from year to year, and sometimes even several times a year. That is why in this article we deliberately do not present exact figures as definitive fact – always check the version of the law in force at the time you are dealing with a specific situation.

Areas that change most often

An entrepreneur should keep track of several topics that are affected regularly. This is where changes to the law show up most visibly in your cash flow.

• Personal and corporate income tax, including the rates and the thresholds for the lower bands
• Contributions to the Social Insurance Agency (Sociálna poisťovňa) and health insurance companies, especially the minimum and maximum assessment bases
• Value added tax and the conditions for VAT registration
• Flat-rate expenses and the conditions under which sole traders can claim them
• Local taxes and fees set by municipalities

Who the changes will affect most

The extent of the impact depends on the legal form of your business. A sole trader claiming flat-rate expenses deals with different matters than a limited liability company (s.r.o.) that employs people. Employers must follow changes in the contribution burden and in payroll administration, while a small business owner without employees focuses mainly on their own contributions and tax return. Companies with an international reach must also follow European legislation.

What to watch out for in practice

The most common mistake is relying on last year’s figures. If your payroll or accounting software does not update the rates automatically, you risk an incorrect calculation. Another risk is transitional provisions – an amendment may apply to only part of the year or relate to income earned after a certain date. So with every major change, check when it takes effect and which period it applies to.

How to prepare for the changes

We recommend setting up a simple routine: once a quarter, check whether an amendment that concerns you is on the way, and before the end of the year, go through the changes planned for the following period. The key is not to rely on a single discussion on social media, but to work from official sources and from advice given by an expert. A tax adviser in particular can translate changes to the law directly into your situation and point out impacts that are not obvious at first glance.

When to approach an expert

If you are planning a larger investment, a change of legal form or hiring employees, it is worth going through the figures with someone who follows legislation every day. The time saved and the penalties avoided usually far outweigh the cost of the advice.

Frequently asked questions

Where should I check the current rates and thresholds?

Always work from the version in force of the relevant act as published in the Collection of Laws (Zbierka zákonov), or from the official websites of the Financial Administration (Finančná správa) and the social and health insurers. As the figures change, treat the content of this article as a guide and check the specific values as at the date on which you are dealing with your situation.

How often do tax and contribution laws change?

The most frequently amended areas change at least once a year, usually at the start of the calendar year, but changes can also come during the year. We therefore recommend checking regularly and consulting your accountant whenever you make a major decision.
