## What decides your case

**What does the letter ask, and by when?** The letter states what the tax authority asks for and the response deadline, counted from the notification date.

**Is it a matter of fact or a point of law?** A factual or divergence reply can be filed on your authorisation. Where a reply argues a point of law, we prepare it and you sign and file it in your own name.

**Does your return have to change?** A divergence notice asks you to explain or correct a mismatch with the tax authority's data. A substitute return is needed only if the return has to be corrected.

  > What I value most is that nothing is left half-finished. Our 2024 returns turned into a complicated case: while the matter was still being regularised, the Tax Authority created instalment plans on its own initiative, and the portal kept showing amounts with no real basis behind them. …
