This page describes the tax and customs compliance picture across every revenue rail and every market the platform serves. Avvyland Limited is a United Kingdom company with founders resident in the United Kingdom, and the platform launches digital-goods rails (the web Progressive Web App and the iOS and Android native apps) first, with physical-goods sales engaging at the manufacturing-and-shipping phase. The page is organised by regime — United Kingdom Corporation Tax first, then United Kingdom Value-Added Tax, then the cross-border Value-Added Tax surface, then country-specific obligations, customs, the United States picture, the Apple and Google in-app purchase tax surface, and finally the audit-and-retention regime that ties everything together. Every numeric figure on this page is published by a primary authority — His Majesty's Revenue and Customs, the European Commission, statutory instrument, or a named treaty — and no internal figure appears here. The page is intended to be readable as a single regulatory briefing rather than as a checklist, and the compliance calendar that operationalises it lives in the operations section.
The Corporation Tax computation engine applies the three-rate structure: the small profits rate of nineteen per cent on profits at or below £50,000, marginal relief between £50,000 and £250,000, and the main rate of twenty-five per cent above £250,000. Both thresholds are divided by one plus the number of associated companies and pro-rated for short accounting periods, and the marginal relief uses the standard fraction (three divided by two hundred) at section 18B(2) of the Corporation Tax Act 2010. The compliance calendar tracks the CT600 return due twelve months after the end of the accounting period and the Corporation Tax payment due nine months and one day after the end of the accounting period; chargeability for the first accounting period is notified to His Majesty's Revenue and Customs within three months of the start of that period under section 55 of the Finance Act 2004.
A watchlist triggers when annual augmented profits cross £1.5 million (the "large company" Quarterly Instalment Payments threshold) or £20 million (the "very large company" threshold), both divided by one plus the number of related companies; on trigger, the instalment dates are added to the calendar. The computation engine identifies loss-relief routing per accounting period: carry-forward against future trade profits under section 45 or section 45A of the Corporation Tax Act 2010, current-year set-off, or carry-back to the immediately preceding twelve months. The default for a first-year loss is carry-forward under the section 45A regime, which applies the five-million-pound deductions allowance and the fifty-per-cent restriction. A Patent Box election decision is surfaced on the calendar when a United Kingdom or European patent on the block-connection geometry is granted, using the Corporation Tax Act 2010 Part 8A regime with the nexus formula.
As a first-time Research and Development claimant, the platform pre-notifies His Majesty's Revenue and Customs within six months of the end of the first accounting period for which a claim is intended, using the online pre-notification service. Failure to pre-notify voids the claim — a hard launch blocker. Each Research and Development claim under the merged Research and Development Expenditure Credit scheme or the Enhanced Research and Development Intensive Support regime is submitted with the Additional Information Form. Enhanced Intensive Support applies where the company is loss-making and Research and Development expenditure is at least thirty per cent of total expenditure, producing an extra eighty-six per cent deduction (total one hundred and eighty-six per cent) and a payable credit at fourteen-and-a-half per cent; otherwise the merged Research and Development Expenditure Credit scheme at twenty per cent applies. The post-1 April 2024 restrictions apply: territoriality (overseas contractor and externally provided worker costs largely excluded); claim-ownership (only the entity contractually liable for the Research and Development may claim); the Pay-As-You-Earn and National Insurance Contributions cap on the payable credit (£20,000 plus three hundred per cent of the company's Pay-As-You-Earn and National Insurance Contributions liability); and the going-concern requirement.
Capital allowances on plant and machinery are claimed in a defined order: the Annual Investment Allowance at one hundred per cent on the first £1 million of qualifying expenditure per year; full expensing at one hundred per cent first-year allowance on main-rate plant for companies; the forty-per-cent first-year allowance on main-rate plant for expenditure from 1 January 2026 where the Annual Investment Allowance is exhausted; and writing-down allowance on the residue (fourteen per cent main pool from 1 April 2026; six per cent special-rate pool). Standalone injection-mould tooling is classified as plant and machinery and is not entered in the Capital Goods Scheme register by default; that register applies only to assets within VAT Notice 706/2 categories (computers at or above £50,000; ships, aircraft, hovercraft at or above £50,000; land or buildings at or above £250,000; refurbishment at or above £250,000). Several anti-avoidance and large-group regimes — Diverted Profits Tax (group threshold above £10 million), the Senior Accounting Officer regime (turnover at or above £200 million or balance sheet at or above £2 billion), and the Multinational and Domestic Top-Up Tax under the Pillar Two framework (consolidated revenue at or above €750 million) — are not engaged at any foreseeable scale and sit on the watchlist.
Voluntary Value-Added Tax registration is submitted before the first material tooling invoice or other large pre-launch input-Value-Added-Tax-able expense, with the effective date set so every material pre-launch input is recoverable on the first return; this is a hard launch blocker. The compliance calendar monitors the backwards-look rolling twelve-month taxable turnover crossing £90,000, which forces registration within thirty days, effective from the first day of the second month after crossing; the forward-look reasonable belief that the next thirty days' taxable turnover will exceed £90,000, which requires immediate notification; and the de-registration trigger when turnover falls below £88,000.
The Standard accounting scheme operates at launch — not Cash Accounting (with joining and leaving thresholds at £1.35 million and £1.6 million), not Annual Accounting (the same thresholds), and not the Flat Rate Scheme (joining and leaving thresholds at £150,000 and £230,000, which would be exceeded materially by first-year expectations and which additionally restricts input-Value-Added-Tax recovery on services). The cadence is quarterly returns; monthly returns are requested if the business is in a regular repayment position, and the HMRC stagger pattern aligns with the financial year-end. Records are kept in Making-Tax-Digital-functional software — Xero, QuickBooks, FreeAgent, or Sage Business Cloud — with digital links maintained at every stage of the data chain, and no manual re-typing is permitted.
The Value-Added Tax engine determines the tax point per supply under section 6 of the Value Added Tax Act 1994 and Notice 700. Early-launch pre-orders through the Stripe SetupIntent flow generate no tax point because no funds are captured, no invoice is issued, and no goods are supplied. Manufacturing-phase physical-product supplies generate a tax point on the earlier of capture date or dispatch date. Artificial-Intelligence-credit subscriptions through the Stripe web rail generate a tax point on capture date, subject to single-purpose-voucher characterisation. Inbound services from non-United-Kingdom suppliers generate a tax point on the earlier of invoice date or payment date, with the reverse charge applying.
Manufacturing-phase physical-product supplies — blocks, fasteners, and delivery — to United Kingdom consumers are charged at twenty per cent, and delivery follows the liability of the main supply; no reduced or zero rate applies to construction blocks. Artificial-Intelligence-credit subscriptions to United Kingdom consumers through the web rail are charged at twenty per cent and priced inclusive of Value-Added Tax per the Price Marking Order 2004. Once registered, the platform self-accounts for Value-Added Tax under the reverse charge on business-to-business electronically-supplied services received from non-United-Kingdom suppliers (such as OpenAI, Replicate, Stability AI, Tripo, Meshy, and hyperscalers); output Value-Added Tax and input Value-Added Tax are declared on the same return; the net cash impact is nil for a fully-taxable business, and pre-registration reverse-charge supplies count toward the £90,000 mandatory-registration threshold. On the first Value-Added Tax return after registration, a pre-registration input-Value-Added-Tax schedule lists every recoverable invoice within four years before registration for goods still on hand or used for taxable supplies and six months before registration for services.
The Finance Act 2021 Schedule 24 points-based late-submission regime is tracked: four points trigger a £200 penalty per subsequent late return; points expire after twenty-four months of compliance. Late-payment penalties under Schedule 26 (as amended by Statutory Instrument 2025/589 from 1 April 2025) apply at no penalty for the first fifteen days if paid (or with a Time-to-Pay agreement), three per cent of unpaid for the sixteenth to thirtieth days, and a further three per cent plus ten per cent per annum daily from the thirty-first day. All Value-Added Tax records — sales and purchase invoices and receipts, the Value-Added-Tax account, imports and exports records (including Postponed VAT Accounting monthly statements), and return working papers — are retained for six years under Schedule 11 paragraph 6 of the Value Added Tax Act 1994; One-Stop Shop and Import One-Stop Shop records have ten-year retention, and the Capital Goods Scheme retention runs for the full adjustment period (five or ten years).
Customer refunds use a credit note issued within fourteen days of agreement, with the output-Value-Added Tax adjustment made in the period of issue. Bad-debt relief under section 36 of the Value Added Tax Act 1994 may be claimed when six months from the later of the payment-due date or the supply date have elapsed, the debt has been written off, and (for a Value-Added-Tax-registered debtor) written notification has been sent to the debtor within seven days of the claim under regulation 168 of the Value Added Tax Regulations 1995. Chargebacks are not refunds: output Value-Added Tax was correctly declared at the original tax point, and recovery, if and when conditions are met, goes through bad-debt relief. Artificial-Intelligence credits are characterised by default as single-purpose vouchers under Schedule 10A of the Value Added Tax Act 1994; tax-advisor confirmation runs before the terms and conditions go live.
Consumer prices are displayed inclusive of Value-Added Tax. Order confirmation emails show the simplified-invoice fields under Notice 700 §16.6: supplier name and Value-Added-Tax registration number; date; description of goods or services; total Value-Added-Tax-inclusive amount; and the rate and total per Value-Added-Tax rate. Value-Added-Tax-group registration under sections 43 to 43D of the Value Added Tax Act 1994 is a watchlist item — relevant only if a United Kingdom subsidiary forms, an acquisition occurs, or the company is acquired into a United Kingdom group.
The platform registers for Non-Union One-Stop Shop in Ireland — chosen as the Member State of Identification for English-language tax administration, common-law familiarity, and the Irish Revenue dedicated Non-Union One-Stop Shop team — at least one full calendar quarter before the first European Union consumer purchase of Artificial-Intelligence credits through the Stripe web rail. Registration takes effect from the first day of the calendar quarter following application under Article 57d of Council Implementing Regulation 282/2011, and this is a hard launch blocker. The European Union ten-thousand-euro distance-selling de-minimis threshold does not apply: the threshold is an European-Union-established-seller concession, and the United Kingdom is non-European-Union-established for Value-Added Tax purposes after Brexit, so the first euro of business-to-consumer electronically-supplied-service revenue to a European Union consumer is destination-Value-Added-Tax-taxable.
The Stripe web checkout determines each European Union consumer's Member State using two non-contradictory pieces of evidence under Article 24b of Council Implementing Regulation 282/2011: billing address, IP geolocation, the Bank Identification Number country, the bank-account country, or the mobile country code. Borderline cases — Virtual Private Network users, mismatched billing and IP — are flagged for manual review by the Stripe Tax engine, and the two-evidence determination is persisted per transaction. A quarterly Non-Union One-Stop Shop return is filed through Irish Revenue's Online Service by the end of the month following each calendar quarter, in euros: net-of-Value-Added-Tax amounts, Value-Added-Tax amounts, and applicable rates are aggregated per destination Member State, a single payment goes to the Member State of Identification, which redistributes to consumer-Member-State treasuries, and conversion of non-euro invoices uses the European Central Bank rate on the last day of the quarter. Records are retained for ten years from the end of the calendar year of supply. Pricing display for European Union Member States is either a uniform headline price with variable net margin per destination rate or a net-uniform price with variable displayed price per Member State; the decision is taken before Stripe Tax configuration.
The Stripe Tax destination-rate engine applies each Member State's standard rate as published by the European Commission, and the current range is seventeen per cent (Luxembourg) to twenty-seven per cent (Hungary); Estonia raised its standard rate from twenty-two to twenty-four per cent from 1 July 2025, and Slovakia raised to twenty-three per cent from 1 January 2025, with rate tables refreshing quarterly. When a deferred European Union physical-goods expansion is approved, the platform registers for the Import One-Stop Shop in one Member State of Identification before selling imported goods with intrinsic value not exceeding €150 per consignment to European Union consumers. As a non-European-Union-established seller, the platform appoints an European-Union-established intermediary (jointly liable for Value-Added Tax) under Article 369m. Consignments above €150 — outside Import One-Stop Shop scope — ship Delivered Duty Paid through a customs broker who pre-pays destination Value-Added Tax and customs duty at checkout (the default for serious expansion), rather than Delivered Duty Unpaid, which would transfer the importer-of-record burden to the consumer and is avoided due to refusal risk. Each calendar quarter the platform runs a three-rail reconciliation across the United Kingdom Value-Added-Tax return, the Non-Union One-Stop Shop return for that quarter, the Apple App Store Connect developer payout reports, and the Google Play Console developer payout reports; the reconciliation produces a single audit-trail entry that ties the views together, mismatches are tracked to closure, and the procedure is documented before the early launch.
Each market with material sales engages a national obligation in addition to the cross-border Value-Added-Tax position. Germany's Verpackungsgesetz registers packaging on the Lucid system. France's anti-waste regime (loi Anti-Gaspillage) registers with the Citeo eco-organisation. Italy's Sistema di Interscambio handles electronic invoicing, and the Consortium for Packaging registers packaging. Spain's Sistema Inmediato de Información handles real-time Value-Added-Tax reporting, and Law 7/2022 governs producer responsibility. The Netherlands' Verpact registers packaging. Country-specific Extended Producer Responsibility for European Union member-state sales engages alongside the tax position and is owned in this section because the obligations intersect.
For physical-goods movements across the United Kingdom border, the platform holds an Economic Operators Registration and Identification number issued by His Majesty's Revenue and Customs, and customs declarations run through the Customs Declaration Service. For goods moving between the United Kingdom and the European Union, the Trade and Cooperation Agreement Rules of Origin determine preferential origin and tariff treatment; the platform documents the bill of materials and origin of each input so the goods meet either the wholly-obtained or the substantially-transformed test for preferential origin, and customs valuation uses the transaction-value method with documented uplifts for licence fees, royalties, and other dutiable elements. Northern Ireland goods movements engage the Windsor Framework: goods staying in Northern Ireland use the United Kingdom Internal Market Scheme to avoid European Union tariffs, and goods at risk of moving into the European Union pay European Union tariffs unless the United Kingdom Internal Market Scheme rules apply.
The South Dakota versus Wayfair decision established economic nexus across the United States, and the platform monitors per-state nexus thresholds and registers in every state where economic nexus is established; sales-tax automation (Avalara, TaxJar, or Stripe Tax) handles per-state collection and remittance. Digital-goods taxability varies by state — Artificial-Intelligence credits are taxable in some states and exempt in others — and the automation engine applies the per-state rule. Section 321 status governs small-shipment customs treatment for physical goods imported into the United States. Marketplace facilitator state law engages in the marketplace phase: where the platform qualifies as a "marketplace facilitator", state sales-tax collection shifts to the platform even on designer-driven sales; this is analysed state by state with a United States state-tax advisor. State business taxes — Delaware Franchise Tax for any United States subsidiary, Texas Margin Tax, Washington Business and Occupation Tax, and so on — engage with United States expansion and are surfaced as the platform's structure evolves.
Apple App Store Connect and Google Play Console handle Value-Added Tax on consumer purchases in the iOS and Android rails. Apple and Google are deemed sellers for these supplies in their respective storefronts and pay the relevant destination Value-Added Tax themselves; the platform receives a developer payout net of platform commission and Value-Added Tax. Revenue recognition under Financial Reporting Standard 102 section 23 reflects this characterisation: the platform recognises revenue on the net amount received from Apple or Google rather than the gross consumer price, and the default working position is confirmed with a tax advisor. The native-app launches engage tax and trader setup in the corresponding storefront — tax forms (W-8BEN-E equivalent), banking, trader information, and the developer-payout configuration — and each native-app launch is gated on completion of its storefront setup.
The audit log records every tax event: Value-Added-Tax return submissions, One-Stop Shop quarterly exports, reverse-charge invoices, pre-registration input recovery, credit-note issuance, bad-debt-relief notifications, chargebacks, capital-allowance claims, Research and Development pre-notifications, Research and Development claims, Patent Box elections, Capital Goods Scheme adjustments, three-rail reconciliation runs, customs declarations, Economic Operators Registration and Identification numbers, Apple and Google payout receipts, and United States per-state nexus crossings. Retention runs at six years for the standard Value-Added-Tax records and ten years for One-Stop Shop and Import One-Stop Shop records, with extended retention for the Capital Goods Scheme adjustment period; the retention regime survives any database migration or storage-tier change.
