Reference
The accountant's library
Structured practical references that start with a work question, explain the treatment, source and boundary, then lead to a lesson or tool where you apply it.
VAT: registration, invoicing and the return
What you collect on the authority's behalf, what you deduct of what you paid, and the difference is what you remit. The tax invoice is the condition that makes the deduction possible at all.
Practical output: Work note: VAT: registration, invoicing and the return — A structured explanation, every official rate with source and review date, then a direct path to a lesson, tool or track.
A decision from the reference: Output tax is what you collect from customers on your standard-rated sales. Input tax is what you paid suppliers on your purchases. The net between the two accounts is what is remitted for the period — or refunded, if input exceeded output.

Zakat: the base, the rate and the return
Zakat is not a percentage of profit but of a base built from long-term sources of funding less the non-zakatable assets they funded. That distinction is the first thing a beginner gets wrong.
Practical output: Work note: Zakat: the base, the rate and the return — A structured explanation, every official rate with source and review date, then a direct path to a lesson, tool or track.
A decision from the reference: The base starts from equity and long-term liabilities — what funded the business and stayed in it — then deducts net fixed assets and long-term investments, because those are funds settled into assets that are not zakatable.

E-invoicing: what changed in your daily work
An invoice is no longer a sheet you print but a structured document generated by a system and connected to the authority's platform. The practical effect on an accountant is larger than the name suggests.
Practical output: Work note: E-invoicing: what changed in your daily work — A structured explanation, every official rate with source and review date, then a direct path to a lesson, tool or track.
A decision from the reference: The first phase required invoices to be generated electronically in a structured format, ending acceptance of handwritten or scanned invoices. The second added integration with the authority's platform, rolled out in waves by revenue size.
