PLN 10,000 Limit in KSeF - Lifeline or Trap for the Smallest Businesses?

The Ministry of Finance is working on rules that would introduce an exception to the National e-Invoicing System (KSeF) for micro-entrepreneurs: if the value of invoices issued outside KSeF does not exceed PLN 10,000 gross in a given month, the business may not be obliged to register them in the system. On the one hand, this is a breather for the smallest firms; on the other, it may create new traps and risks.

What is this "PLN 10,000 limit"?

• The draft rules provide that micro-businesses will be able to issue invoices outside KSeF as long as the total gross value of those invoices in a month does not exceed PLN 10,000.
• The limit applies to the sum of all invoices issued outside KSeF, not to individual documents - even a large invoice can remain "outside the system" as long as the total of all such invoices does not exceed the threshold.
• The exception is meant to apply during a transitional phase, until KSeF becomes mandatory for the smallest entities as well (scheduled for January 2027).
• The idea does not mean complete freedom - once the limit is exceeded, invoices must be issued in KSeF and you cannot go back to the old way of invoicing.

Who does this limit give hope to?

• Sole proprietorships (JDG) and micro-businesses with low monthly turnover.
• Seasonal businesses that occasionally make larger sales but stay below the threshold for most months.
• Those who worry about the cost of implementing KSeF and want time to adapt without abrupt consequences.

But the risks are significant too

• Exceeding the limit, even by a small amount, automatically forces you to use KSeF - a regulatory jump in the middle of the month.
• The need to constantly monitor the total of invoices "outside the system" - additional accounting duties and a risk of errors.
• Potential penalties or corrections if the tax office decides that the threshold was exceeded and the invoices were not entered into KSeF.
• This tool can act as a kind of "trap", in which even a one-off higher-value sale catches the business owner out with an obligation to migrate documents to KSeF.

How to prepare and protect yourself

1. Monitor the totals of invoices outside KSeF - use automated systems so you know when you are approaching the threshold.
2. Adapt your accounting system - it must distinguish between KSeF and non-KSeF invoices and add up their value.
3. Plan your sales - if you expect a larger order, plan to invoice it through KSeF to avoid exceeding the limit.
4. Structural consultation - consider whether part of the business could be moved to a structure that will enter KSeF sooner, to avoid a large volume of documents outside the system.
5. Formal safeguards - well-drafted contracts, sales documentation and correction mechanisms in case invoices need to be migrated.

Our comment

The PLN 10,000 limit is a gesture towards micro-entrepreneurs, but it is also a subtle trap. It offers flexibility, but requires discipline in tracking invoices and anticipating when you will cross the threshold. For businesses operating close to the threshold, the limit can be a source of unexpected complications.

At Global Tax Partners, we help businesses design systems that continuously monitor invoice amounts, predict the moment of entry into KSeF and minimise the risk of errors.
