VAT Disputes

VAT Dispute Solicitors — Assessments, Input Tax, MTIC Fraud Allegations, and Tribunal Appeals

VAT disputes with HMRC can arise from a VAT assessment raising tax you dispute, a refusal of input tax recovery, a partial exemption challenge, a disputed option to tax, or the most serious allegation — MTIC (carousel) fraud, where HMRC alleges that your business knew or should have known of fraud elsewhere in the supply chain and refuses your input tax claim as a result. A specialist VAT dispute solicitor analyses HMRC's position, prepares detailed grounds of challenge, and represents you through statutory review, HMRC ADR, and First-tier Tribunal (Tax Chamber) proceedings.

VATA 1994 s.73 — VAT assessments Input tax & partial exemption MTIC/carousel fraud allegations VAT tribunal appeals
⚠️ VAT assessments and MTIC fraud allegations have strict appeal deadlines — delay is fatal. A VAT assessment must be appealed to HMRC within 30 days of the decision (or 30 days after a statutory review conclusion), and a tribunal appeal must be filed within strict time limits after that. MTIC fraud allegations can result in the refusal of all input tax from a particular supply chain — destroying a business's cash flow. A solicitor acts immediately on receipt of any VAT assessment or input tax refusal.

VAT Disputes — Key Areas

📊
VAT assessments — VATA 1994 s.73 — HMRC may raise a VAT assessment where it believes output tax has been understated or input tax overclaimed. A "best judgment" assessment (s.73(1)) is based on HMRC's estimate where returns are missing or records are inadequate; a corrective assessment follows a compliance check. A solicitor analyses whether the assessment has been raised within the relevant time limits (2 years from knowledge for a best judgment assessment; 4 years otherwise; 20 years for deliberate evasion — VATA 1994 s.77), whether the quantum is correct, and whether HMRC has acted on a proper basis — and prepares the grounds of appeal accordingly.
🔄
Input tax recovery disputes — VATA 1994 s.26 — HMRC may refuse input tax on the grounds that the supply was not used for taxable business purposes (the business purpose test), that the supply was exempt (blocked input tax), or as a result of partial exemption calculations. The partial exemption standard method allocates input tax between taxable and exempt activities by reference to a values-based ratio; the partial exemption special method requires HMRC approval and must give a fair and reasonable result. A solicitor challenges HMRC's partial exemption calculations, disputes blocked input tax refusals, and advises on the de minimis limits (£625/month average and 50% of all input tax).
🏗️
Option to tax — VATA 1994 Schedule 10 — commercial land and buildings are exempt from VAT by default; exercising an option to tax makes supplies of the property taxable, enabling the recovery of input tax on associated costs. HMRC can disapply an option to tax where the buyer uses the property for exempt purposes (the "anti-avoidance" rule — Sch 10 para 12) or where HMRC determines the option was incorrectly notified or should be revoked. A solicitor advises on the validity of an option to tax, challenges HMRC's disapplication decisions, and manages HMRC disputes over the VAT treatment of commercial property transactions.
⚠️
MTIC/carousel fraud allegations — Kittel and Mobilx — in missing trader intra-community (MTIC) fraud, a defaulter disappears without paying VAT collected on a sale; downstream traders unknowingly pass the goods along and reclaim input VAT. HMRC alleges that a business knew (actual knowledge — Kittel v Belgium [2006]) or should have known (constructive knowledge — Mobilx Ltd v HMRC [2010]) of the fraud and refuses all input tax claimed on the affected transactions. A solicitor analyses the supply chain, obtains expert evidence, challenges HMRC's fraud findings, and represents the business at the Tax Tribunal — where the burden of proving knowledge or means of knowledge is on HMRC.
📝
VAT registration and deregistration disputes — compulsory VAT registration applies where the 12-month rolling taxable turnover threshold is exceeded (£90,000 from April 2024). HMRC may require retrospective registration where it determines the threshold was exceeded without registration. HMRC may also refuse deregistration, or challenge a business's VAT registration status (for example, by asserting that two separately registered businesses are a single entity under VATA 1994 s.43/Sch 1 para 2 — disaggregation). A solicitor challenges retrospective registration, disputes disaggregation notices, and advises on voluntary registration and deregistration.
🌍
Place of supply and reverse charge disputes — the place of supply rules (VATA 1994 Sch 4A) determine whether UK or overseas VAT applies to a supply of services. The reverse charge mechanism (VATA 1994 s.8) requires UK VAT-registered businesses receiving certain services from overseas suppliers to account for VAT — failure to apply the reverse charge results in assessment. Post-Brexit, new rules apply to B2C supplies of digital services, goods, and services into the EU. A solicitor advises on the correct VAT treatment, challenges HMRC assessments where the wrong place of supply analysis has been applied, and manages HMRC disputes over cross-border transactions.

Frequently Asked Questions

HMRC has raised a VAT assessment — what are the time limits and my options?

A VAT assessment must generally be made within 2 years of evidence of facts sufficient to justify the assessment coming to HMRC's knowledge (VATA 1994 s.77(4) — for best judgment assessments) or within 4 years of the end of the prescribed accounting period to which it relates (s.77(1)). For deliberate evasion, the limit is 20 years. A taxpayer may appeal a VAT assessment to HMRC in the first instance, request a statutory review (30-day deadline), and then appeal to the First-tier Tribunal (Tax Chamber). A solicitor analyses whether the assessment is in time, correctly calculated, and properly raised — and prepares detailed grounds of appeal.

What is MTIC (carousel) fraud and how does HMRC allege it against my business?

MTIC fraud involves a "missing trader" who collects VAT from a buyer but disappears without paying it to HMRC. The buyer claims back that input VAT, creating a fraud on the public revenue. HMRC alleges that businesses in the supply chain either knew of the fraud (Kittel — actual knowledge: HMRC refuses input tax absolutely) or should have known (constructive knowledge — Mobilx Ltd v HMRC [2010] EWCA Civ 517: HMRC must show the only reasonable explanation for the circumstances was that the business ought to have known of fraud). A solicitor challenges HMRC's analysis of the supply chain, its fraud findings, and its attribution of knowledge to your business — and represents you at the Tax Tribunal, where HMRC bears the burden of proof on all issues.

Can I reclaim VAT on costs incurred before I registered for VAT?

Yes — pre-registration input tax can be reclaimed on goods purchased within 4 years before registration (where the goods are still held at the date of registration) and on services received within 6 months before registration (VATA 1994 s.24(6); VAT Regulations 1995 reg. 111). The goods or services must have been for the purposes of the business that is now VAT-registered. A solicitor advises on the pre-registration input tax claim, challenges any HMRC refusal, and ensures the claim is correctly included in the first VAT return.

HMRC says my option to tax on a commercial property has been disapplied — what are the consequences?

If HMRC disapplies the option to tax (under VATA 1994 Sch 10 para 12 — the anti-avoidance rule, which applies where the buyer or connected person intends to use the building for exempt purposes), the supply reverts to being exempt. The supplier loses the ability to recover input tax on costs associated with the property, and may face an assessment for VAT previously recovered. A solicitor challenges the disapplication, advises on the conditions for the anti-avoidance rule, and — where the rule applies — mitigates the impact through restructuring of the transaction.

What is the partial exemption de minimis limit and why does it matter?

A partially exempt business normally cannot recover input tax directly attributable to exempt supplies, and must apportion residual input tax. The de minimis limit provides an exception: if exempt input tax is no more than £625 per month on average and no more than 50% of total input tax, the business can treat all input tax as deductible (i.e. as if it were fully taxable). A business near the de minimis limit must monitor it carefully each quarter and perform the annual adjustment. A solicitor advises on partial exemption calculations, challenges HMRC's apportionment methodology, and manages the annual partial exemption adjustment and HMRC compliance check.
