UK Accounting Answers. Simplified.

Cited answers from HMRC manuals, legislation, case law, and official guidance — in seconds, not hours.

The Generic AI Problem

Generic AI creates liability, not clarity

ChatGPT and similar tools generate confident answers with no verifiable sources

Answers you can't stand behind

No connection to authoritative sources. Answers may be plausible but legally incorrect.

Citations are vague, incomplete, or entirely fabricated — impossible to verify.

Fabricated authorities — now a profession-wide problem

Early tribunal cases — Harber, Zzaman, Gunnarsson — involved self-representing taxpayers. The profession could once distance itself from that.

In June 2025 that changed. The High Court handed down a combined judgement in Ayinde v London Borough of Haringey and Al-Haroun v Qatar National Bank [2025] EWHC 1383. In Ayinde, a barrister had cited five fake cases. In Al-Haroun, a solicitor submitted 45 citations in support of an £89 million claim — 18 did not exist.

Unusable for professional advice

Cannot be used for professional advice, compliance, or audit defence.

As a practising accountant, I've found Fiscari genuinely useful — particularly for more complex tax planning areas like group relief where the HMRC guidance isn't always easy to navigate. The answers are clearly structured and backed by real citations I can check. It's the kind of support you'd normally pay a telephone tax advisor for, or spend half a morning finding yourself. This has enabled me to provide more value and better offerings to my clients.

Query

What is the VAT treatment for exported goods to EU countries post-Brexit?

Answer

Exports of goods from the UK to EU countries are zero-rated for VAT under the Value Added Tax Act 1994, Group 1, Schedule 8, provided the goods are exported within the required time limits.

Businesses must retain valid evidence of export to support zero-rating, as set out in VAT Notice 703. Acceptable evidence includes official customs documentation and commercial transport documents.

Following the UK's exit from the EU, goods sent to EU member states are treated as exports rather than intra-community supplies, applying the same zero-rating rules as any other international export.
