Lesson 3 — One tax group per VAT rate
The stake. The VAT summary is the part of a tax invoice a reviewer reads first: how much of this document was taxed, at what, and how much VAT sits on it. The summary breaks down by tax group. That one design fact decides whether your summary is useful or unreadable, and it is the single thing in this course most worth settling before you print anything for a customer.
The mental model. A tax group is a bucket you put taxes in, and the summary prints one row per group. Give Standard 5%, Zero-rated and Exempt a group each and you get three rows that mean three different things. Let two categories share a group and the pack cannot split them without guessing — so it does not guess, and it says so on the form instead.
Where to look. The module guide names this setting rather than a menu path, so this course will not invent one: tax groups are part of your accounting configuration, and the change is made there, on the taxes, rather than anywhere in the print pack. The shape you are aiming for is three groups.
| Tax group | What belongs in it | What the summary then prints |
|---|---|---|
| Standard 5% | Taxes charged at the UAE standard rate of 5% | Its taxable amount and its VAT amount |
| Zero-rated | Taxes on zero-rated supplies | Its taxable amount and a zero VAT amount |
| Exempt | Taxes on exempt supplies | Its taxable amount and a zero VAT amount |
A fully zero-rated invoice does not print an empty VAT summary. People expect it to, and it does not. The summary reads the document's own computed tax totals, so zero-rated and exempt supplies appear with their taxable amount and a zero VAT amount. A reader can therefore see that a supply was made and taxed at nothing, which is a different statement from a summary that says nothing at all.
The worked example. Return to the invoice from Lesson 2 with the three groups in place. Standard 5% prints AED 40,000 taxable and AED 2,000 of VAT. Zero-rated prints AED 25,000 taxable and AED 0. Exempt prints AED 10,000 taxable and AED 0. Three rows, AED 75,000 and AED 2,000 at the foot. Now merge zero-rated and exempt into one group: the same invoice prints a single combined row of AED 35,000 marked "Mixed categories - review", with the same totals, less information, and a reviewer's question you now have to answer by hand.
The failure mode. A VAT row says "Mixed categories - review". One tax group contains taxes of different UAE VAT categories, so the breakdown cannot be split without guessing. Give each category its own tax group and print again. Notice what the pack chose to do there: it printed a row that tells the truth about itself rather than a plausible-looking split. A wrong breakdown would have sailed through review. This one does not.
The idea to carry forward: the summary is only as granular as your tax groups, and the row marked for review is the pack refusing to invent a number on your behalf.
