Water bills in myDATA
The water bill has its own E3 code, different from energy and telecommunications.
Short answer
- Category: 2.4 · General expenses with VAT deduction.
- E3 code: E3_585_012 · Water supply.
- VAT classification: VAT_361, with the line’s net value as the amount.
- The combination is allowed for document types 1.1, 2.1, 5.2 (credit note) and 13.1 (AADE table).
What to check
- That the bill is for the business premises.
- If the document has several lines, each line is classified separately; lines that are not water consumption do not necessarily take the same code.
- Do not classify it as “Energy” (E3_585_011) out of habit: water supply has its own code.
Why it matters
If the bill is left unclassified, its amount is prefilled in E3 under code 585_016 together with every other unclassified expense (AADE’s E3 FAQ).
