The Polish Ministry of Finance published JPK_V7M and JPK_V7K, as an electronic document template, in the Central Repository of Electronic Document Templates (CRWDE) on the ePUAP platform. JPK_V7M is used for monthly declaration, whereas JPK_V7K is for quarterly declaration. JPK is based on SAF-T, but there are significant differences between both files.
