Why KLU should not be read as if it were KBLI

KLU is the tax layer, not the primary business-activity classification for every operational decision. In practice, KLU helps interpret tax norms, filing context, and reporting logic, while KBLI is used to describe the economic activity itself. The two layers should therefore be read together rather than treated as interchangeable.

How to use a KLU page correctly

Start from the real business activity and make sure the linked KBLI is still relevant. Then use the KLU page to read the norms, tax notes, and DJP validation points. If the KLU looks overly broad, the team should return to the activity mapping and re-check whether the cross-layer mapping is actually correct.

The risk of reading KLU in isolation

When KLU is read separately from KBLI and the real business structure, it often becomes just a tax-norm number without context. That weakens both budgeting and filing because the user may think the code is settled while the activity description, company records, and tax treatment are still misaligned.
