Film partnerships, employee benefit trusts, contractor loan schemes and stamp duty planning were marketed to doctors, footballers, business owners and IT contractors, often by regulated advisers who described them as tested and low risk. When HMRC succeeded, the participants were left with the original tax, interest running back years, and in many cases penalties. The question that follows is whether the adviser who recommended the arrangement should carry that loss.*** ## What Went Wrong With These Arrangements The schemes varied enormously in structure but shared a common weakness. Each depended on a technical reading of legislation that HMRC disputed and that the courts ultimately rejected. Participants were rarely told the arrangement was untested, still less that [HMRC had signalled an intention to challenge it](https://taxdisputes.co.uk/hmrc-tax-investigations/), and many were shown counsel's opinion described as approval when it was heavily qualified, the sort of failing our [negligence team](https://professionalnegligenceclaimsolicitors.co.uk/professional-negligence-faqs/) examines closely. The financial consequences arrived years later. Accelerated payment notices required tax to be paid before any appeal was heard. Interest accumulated across the intervening period. For some participants the eventual liability exceeded the sums originally sheltered. Where that loss flows from advice that fell below a competent standard, a claim may lie, and our [professional negligence solicitors](https://professionalnegligenceclaimsolicitors.co.uk/professional-negligence-claims/) assess these cases regularly alongside the tax specialists at [our tax disputes practice](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/). ## Who Can Be Sued Responsibility is often shared, and identifying the right defendant matters as much as establishing the breach, as our [case studies](https://professionalnegligenceclaimsolicitors.co.uk/case-studies/) show. Independent financial advisers who recommended the arrangement owe duties of suitability and are usually regulated, which brings both a professional indemnity policy and an alternative complaints route, considerations covered in our [guide to negligence claims](https://professionalnegligenceclaimsolicitors.co.uk/professional-negligence-claims/). Accountants who advised on or implemented the planning owe a contractual and tortious duty to advise competently. Promoters and scheme designers occupy a different position. A claim against a promoter may rest on misrepresentation about the arrangement's prospects rather than on negligent advice, particularly where marketing material overstated the degree of certainty. Many promoters have since dissolved, which makes the regulated adviser the practical target. Our guidance on [suing professional advisers for business losses](https://professionalnegligenceclaimsolicitors.co.uk/can-directors-sue-professional-advisers-for-business-losses/) covers the analysis, and our [glossary of negligence terminology](https://professionalnegligenceclaimsolicitors.co.uk/glossary-key-negligence-legal-terminology-terms-guide-a-to-z-litigation-advice/) explains the concepts involved. ## What Has to Be Proved The starting point is that a scheme failing does not by itself prove negligence. Tax planning carries risk, and an adviser who explained that risk honestly has not breached any duty simply because HMRC won its [appeal](https://taxdisputes.co.uk/hmrc-tax-appeals-solicitors-london/), a threshold our [glossary](https://professionalnegligenceclaimsolicitors.co.uk/glossary-key-negligence-legal-terminology-terms-guide-a-to-z-litigation-advice/) explains. The claim turns instead on what the client was told. Was the arrangement presented as tested when it was novel. Was the client informed that HMRC was known to be challenging schemes of that type. Was the risk of failure quantified at all, or described in terms that concealed it. Was the arrangement suitable for this particular client given their circumstances and appetite for risk. Was the client told about the possibility of an accelerated payment notice requiring payment long before any appeal. Where the answers reveal advice that no reasonably competent adviser would have given, the breach is made out, and our [case studies](https://professionalnegligenceclaimsolicitors.co.uk/case-studies/) illustrate how these arguments run in practice. ## The Limitation Problem Limitation is the single greatest obstacle in these claims and the reason many potential claimants discover they are too late, which is why we address it before anything else in a [second opinion](https://professionalnegligenceclaimsolicitors.co.uk/second-opinion-legal-fixed-fee-new-representation-litigation-advice/). The ordinary period is six years from the date the [damage occurred](https://professionalnegligenceclaimsolicitors.co.uk/limitation-period-in-professional-negligence-claims/). The difficulty is identifying that date, because it may be when the client entered the arrangement and paid fees, rather than when HMRC issued an assessment years afterwards. A secondary period assists where the claimant could not reasonably have known they had suffered loss. That allows three years from the date of knowledge, subject to an absolute longstop of fifteen years from the negligent act, after which no claim survives regardless of knowledge. For arrangements entered into in the early 2010s, that longstop is now closing. Anyone who suspects they have a claim should take advice immediately rather than waiting for their tax position to be finalised, and our detailed guidance on the [limitation period in professional negligence claims](https://professionalnegligenceclaimsolicitors.co.uk/limitation-period-in-professional-negligence-claims/) explains how the dates are calculated. ## Running the Tax Dispute and the Claim Together These two matters are connected but separate, and the order in which they are handled affects the outcome of both. The value of a [negligence claim](https://professionalnegligenceclaimsolicitors.co.uk/professional-negligence-claims/) depends on what the [tax dispute](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/) ultimately costs, so a claim brought before the tax position settles may be difficult to quantify. Waiting for the tax position to conclude, however, risks limitation expiring in the meantime. The usual answer is to protect the limitation position while the tax dispute continues, whether by issuing and staying proceedings or by agreeing a standstill with the adviser's insurers. Meanwhile the tax liability itself should be contested properly, whether through an [HMRC internal review](https://taxdisputes.co.uk/hmrc-internal-review-appeals-solicitors-london/), an [appeal to the First-tier Tribunal](https://taxdisputes.co.uk/first-tier-tax-tribunal-solicitors-london/), or negotiation over [penalties](https://taxdisputes.co.uk/hmrc-penalties/), since every pound recovered there reduces the loss and every pound of penalty avoided strengthens the overall position. ## When Enforcement Arrives Before Resolution Many people in this position face collection action while the underlying arguments remain unresolved. HMRC can pursue individuals to bankruptcy and companies to [winding up](https://windinguppetitionsolicitors.co.uk/opposing-a-winding-up-petition/), and those proceedings do not pause because a claim is being prepared, so [enforcement must be handled in parallel](https://taxdisputes.co.uk/hmrc-enforcement-action/). Where a statutory demand has been served there may be grounds to [set it aside](https://windinguppetitionsolicitors.co.uk/statutory-demand-set-aside-lawyers-london-hmrc/). Where a petition has been presented against an individual, our colleagues explain the position on their page dealing with [bankruptcy petitions](https://windinguppetitionsolicitors.co.uk/bankruptcy-advice/) and on [annulment applications](https://windinguppetitionsolicitors.co.uk/bankruptcy-annulments/) where an order has already been made. Negotiating instalment terms with HMRC may also buy the time needed, as described in their guidance on [negotiating before proceedings are issued](https://windinguppetitionsolicitors.co.uk/how-to-negotiate-with-hmrc-before-a-winding-up-petition-is-issued/). ## What Can Be Recovered Damages aim to put the claimant in the position they would have occupied had the advice been competent, a measure explained in our [FAQs](https://professionalnegligenceclaimsolicitors.co.uk/professional-negligence-faqs/). In practice that usually means the difference between what they paid and what they would have paid had they never entered the arrangement, together with the cost of the resulting [penalty exposure](https://taxdisputes.co.uk/hmrc-penalties/). Fees paid to the promoter and adviser are ordinarily recoverable, as are the professional costs of dealing with the resulting HMRC enquiry. Interest is frequently the largest single component, since it accrues from the original due date rather than from the date HMRC raised the assessment. Penalties may also be recoverable, though an adviser will often argue the client contributed to the position by failing to read documents or by understating their own circumstances. Contributory negligence arguments of that kind are common and need to be anticipated, which is why we recommend an early [fixed fee second opinion](https://professionalnegligenceclaimsolicitors.co.uk/second-opinion-legal-fixed-fee-new-representation-litigation-advice/) before proceedings are contemplated. ## How We Can Help Our dual qualified solicitors and barristers act for individuals and businesses pursuing claims arising from failed tax planning, from the initial assessment of merits and limitation through to [issuing proceedings](https://professionalnegligenceclaimsolicitors.co.uk/start-issue-professional-negligence-court-claim-case-legal-advice/) and trial. Because we also run a substantial tax disputes practice, we handle the HMRC side and the negligence claim as a single coordinated strategy rather than instructing separate teams who do not speak to one another. If you entered a tax arrangement that HMRC has challenged, take advice on limitation before anything else, because that question determines whether you have a claim at all.

[Check My Case Now ✔](https://professionalnegligenceclaimsolicitors.co.uk/litigation-case-assessment-form/) ### Frequently Asked Questions (FAQs) 1. Does a failed tax scheme automatically mean my adviser was negligent? No. Planning carries risk, and an adviser who explained that risk honestly has not breached any duty. The claim turns on what you were actually told, as our [negligence solicitors](https://professionalnegligenceclaimsolicitors.co.uk/professional-negligence-claims/) explain. 2. How long do I have to bring a claim? Generally six years from the damage, or three years from knowledge, subject to a fifteen year longstop. For arrangements entered in the early 2010s that longstop is closing. See our guidance on [limitation periods](https://professionalnegligenceclaimsolicitors.co.uk/limitation-period-in-professional-negligence-claims/). 3. Should I settle with HMRC before suing my adviser? Not necessarily, and the sequencing needs care. Protect limitation first, then contest the tax position through an [appeal](https://taxdisputes.co.uk/hmrc-tax-appeals-solicitors-london/) since every pound recovered reduces your loss. 4. The promoter has been dissolved. Can I still claim? Often yes, against the regulated adviser who recommended the arrangement to you. Identifying the right defendant is part of the initial assessment, covered in our [second opinion service](https://professionalnegligenceclaimsolicitors.co.uk/second-opinion-legal-fixed-fee-new-representation-litigation-advice/). 5. What if HMRC is already pursuing me for the money? Deal with enforcement immediately and separately. Where a statutory demand has been served you may be able to [set it aside](https://windinguppetitionsolicitors.co.uk/statutory-demand-set-aside-lawyers-london-hmrc/), and our colleagues advise on [bankruptcy petitions](https://windinguppetitionsolicitors.co.uk/bankruptcy-advice/).
