E‑delivery in Tax Proceedings: Why Precision Matters

Electronic delivery of documents has become a fundamental element of tax proceedings in Poland. It is not merely a technical tool for communication with tax authorities, but a mechanism with direct legal consequences, affecting the validity of decisions, the calculation of procedural deadlines, and the ability of authorities to continue a case.

In general, tax authorities can deliver documents electronically through two main channels: the e‑Tax Office portal or the official e‑Delivery system. Whereas the use of the e‑Tax Office requires prior consent.

Particular attention is required where a taxpayer has appointed a representative. In such cases, correspondence should generally be sent to the representative at the address specified in the power of attorney. However, in practice, complications arise when authorities use a different channel, in particular e‑Tax Office, than the one indicated in the power of attorney. Diverging court decisions mean that it is not always clear whether priority should be given to the e‑Tax Office or the e‑Delivery system.

Defective delivery may have far‑reaching consequences. It can prevent deadlines from starting, undermine the effectiveness of a tax decision, or even render it legally invalid.

In this context, taxpayers and their advisers must carefully monitor how documents are delivered. Ensuring that delivery methods, consents and addresses are consistent and up to date is essential, as even minor procedural errors can significantly affect the outcome of tax proceedings.
