What you will learn

The LoA comes first. The assessment comes after.

Validity of the LoA

Who signed it, when it was served, which Revenue Officer is named. The three questions that get a Final Assessment Notice (FAN) cancelled.

New RO, old LoA

Your audit was handed to another Revenue Officer (RO) without a new LoA. What the Supreme Court said in Medicard, McDonald’s and Sony.

The timeline

The Notice of Discrepancy (NOD), Preliminary Assessment Notice (PAN), Formal Letter of Demand (FLD) and Final Decision on Disputed Assessment (FDDA). How many days you have at each stage, and how late the LoA issue can still be raised.

Your protest

You draft a protest to your own LoA during the session and take the template home for your business, your family or yourself.
