1. Lack of Tax Planning and Knowledge of the Law

Many deal with taxes only once a year — during tax filing season — and then “forget” about them for the rest of the year.
This passive approach to tax obligations contributes to the unfortunate statistic that the vast majority of small companies pay more to the state than necessary.
Without tax planning, a company can easily overlook various opportunities for legal tax optimization.

For example, in Slovakia, the law allows companies to reduce their taxable base by paying certain expenses on time.
If a company does not pay invoices for rent, license fees, or consulting services by the end of the year, it cannot claim them as tax-deductible expenses for that year.
Lack of knowledge of such rules means that companies artificially increase their taxable base and end up paying higher taxes, even though with better planning, they could have saved money.

2. Incomplete or Inaccurate Accounting

Accurate accounting is the basic prerequisite for a company to pay only as much tax as it really owes.
If accounting “misses” some information about income or expenses, the result may be a higher taxable profit than in reality.

A common problem, especially in smaller companies, is mixing personal and business finances – for example, when an entrepreneur pays for a company purchase from their personal bank account.
Such an expense may not appear in the company’s books at all, causing the business to lose the opportunity to reduce its taxable base by that expense.

Similarly, inaccurate recording of assets and depreciation deprives a business of valuable deductions.
An example from practice: an entrepreneur bought a car for business use but recorded it only in personal accounting.
Since it did not appear in the company’s accounting records, it was not depreciated for years – meaning the company unnecessarily paid higher taxes.

These cases are far from rare.
The solution is consistent and separate bookkeeping – recording all company transactions in the business accounts, keeping personal and business expenses separate, and ensuring proper recording of every transaction.

3. Failure to Use Available Tax Reliefs and Deductions

Tax laws (both in Slovakia and worldwide) contain numerous legal reliefs, exemptions, and deductions designed to make life easier for entrepreneurs – but only if they know about them and actually use them.

A common reason for unnecessarily high tax payments is simply that the company does not take advantage of all the opportunities available.
For example, expenses for research and development in Slovakia can be additionally deducted from the tax base under the so-called super-deduction.
Thanks to this mechanism, companies can deduct up to 100% of these expenses again, in addition to the standard inclusion in operating costs.
In practice, this means a significant reduction in the final tax.

The problem? Only about 500 Slovak companies per year make use of this benefit, even though there are many more that could be eligible.
A similar trend is visible worldwide – it is estimated that up to 70% of small companies do not claim the available R&D tax credit, thereby missing out on significant savings.

4. Inappropriate Legal Form or Business Structure

The amount of taxes and contributions is greatly influenced by the legal structure of the business.
A sole trader (self-employed person), a limited liability company (s.r.o.), and employees are all taxed differently – and these differences can be substantial.

According to analysts, in Slovakia, the least burdened entrepreneurs are sole traders using flat-rate expenses, while employees pay the highest total amount in taxes and contributions.

In Slovakia, the decision between operating as a natural person (sole trader) or establishing a limited liability company can have a significant impact on overall tax and contribution liabilities.
The same applies to whether profits are paid out as dividends, reinvested, or whether family members are employed in a family business.
All these are strategic decisions with major tax and social contribution implications.

5. Missed Deadlines and Unnecessary Penalties

Sometimes companies pay more not because of bad decisions, but simply because they fail to meet obligations on time.
Tax laws impose fines and late payment interest for submitting returns or paying taxes after the deadline.
These penalties can be seen as unnecessarily paid “extra taxes” that do not result from tax liability but from error — and the amounts are far from negligible.

6. An Overly Conservative Approach and Unwillingness to Optimize

On the opposite end of the spectrum from ignorance lies excessive caution.
It often happens that entrepreneurs or their accountants avoid using certain available deductions or benefits “just to be safe”, to prevent possible complications with authorities.
This strategy may reduce the risk of error but also means that the company voluntarily pays more than necessary.

Tax advisors point out that many accountants are so focused on compliance with all obligations that they no longer have time to look for additional savings for the client.
The result is that while the company fully complies with the law, it fails to use all legal options for tax minimization.

However, tax optimization is not illegal – it is not tax evasion, but a legitimate strategy within the rules.

7. Lack of Professional Assistance (Tax Advisory Services)

Tax matters are complex, and for a layperson, it can be difficult to keep track of all laws, amendments, and available options.
Smaller companies often do not have their own tax specialist and rely on an external accountant who correctly records and files returns but does not focus on finding creative ways to save money.

The solution is collaboration with a qualified tax advisor or auditing firm specializing in optimization.
Experts can identify opportunities that a non-professional might miss.

A good advisor also ensures ongoing tax planning and alerts you to errors (points 1–6 above) so that you can avoid them.
Although professional advice comes at a cost, in the end, it can save you many times more than it costs.

Pay Only What You Must

The good news is that all the above reasons for overpaying taxes can be prevented.
It requires a combination of knowledge, planning, and discipline – ideally under the guidance of an experienced professional.

Every business – whether a small sole trader or a large corporation – should have a clear understanding of its tax obligations and available opportunities.
