Must a sole trader using single-entry accounting have a delivery-service provider?
Short answer
Official materials state that every legal person or taxable entrepreneur, including a sole trader, that falls within the receiving obligation must be able to receive e-invoice through a delivery service. The accounting method is not decisive; the person’s status and the applicable invoicing rules are.
Deciding criterion
Not the accounting system, but the position under the Act VAT.
No derogation
A self-employed person using single-entry bookkeeping also needs an e-invoicing delivery-service provider.
A Simple Solution Enough
Application accountcii A postman is good enough.
Shared approach
SKZOP can give access to the application directly to its accountant.
Detailed explanation
A small sole trader using simple accounting who issues or receives only a few dozen invoices a year does not, according to the recommendation of the Slovak Financial Administration, need to procure an expensive automated system — for example, an account in a digital mail service application will suffice, from which they can download the invoices or make them directly available to their accountant. The obligation to have a contracted digital mail service provider applies regardless of whether the business is a VAT payer or simply a taxable person who does not pay VAT.
As set out in the Act
The obligation to receive electronic invoices via a delivery service arises from Sections 76a and 85o of Act No. 222/2004 Coll. on VAT. The VAT Act does not link this obligation to the method of keeping accounts under Act No. 431/2002 Coll. on Accounting.
Practical examples
- A self-employed tradesperson using single-entry bookkeeping will engage a digital mail service provider and send the downloaded e-invoices to their accountant.
- A self-employed person who is not a VAT payer must be able to receive an e-invoice from a VAT payer, even though they do not declare VAT themselves.
- A small business grants its accountant direct access to the digital mail service application instead of forwarding files.
Most common mistakes
- “Simple accounting is exempt from the obligation to accept e-invoices.” It is the taxable person’s status that matters, not the accounting system.
- “Only VAT payers need the digital mailbox.” The obligation to receive e-invoices also applies to non-VAT payers who are taxable persons.
- “A small sole trader needs a costly ERP system.” According to the recommendation of the Slovak Financial Administration, a simple account in the e-Postman application is sufficient.
Conclusion
Single-entry accounting does not create an exemption; the need for a delivery-service provider follows from the person’s status and obligation to receive e-invoice.
