Uk Vat Return

UK VAT Return Skill (VAT100) v2.0

General reference only. This skill is general tax/accounting reference material for AI-assisted workflows. It has not been reviewed for any specific person's facts, documents, elections, deadlines, residency, filing status, or local procedures. Do not rely on it to file, pay, amend, or take a tax position without review by a qualified professional in the relevant jurisdiction.

Year applicability: Rules in this skill apply across 2024-25, 2025-26, and 2026-27 unless a specific section flags a year-dated change. The pack is read alongside the rate-bearing skills (uk-income-tax-sa100, uk-national-insurance, uk-dividends, etc.) which carry full 3-year tables.

Section 1 — Quick reference

Read this whole section before classifying anything. The workflow runbook is in vat-workflow-base Section 1 — follow that runbook with this skill providing the country-specific content.

Key VAT100 boxes (the boxes you will use most):

Conservative defaults — UK-specific values for the universal categories in vat-workflow-base Section 2:

Red flag thresholds — country slot values for the reviewer brief in vat-workflow-base Section 3:

Flat Rate Scheme — selected sector percentages (2025):

First-year discount: new VAT registrations get a 1% reduction in the FRS percentage for the first year.

Section 2 — Required inputs and refusal catalogue

Required inputs

Minimum viable — bank statement for the period in CSV, PDF, or pasted text. Must cover the full VAT period. Acceptable from any UK business bank: Barclays, HSBC UK, Lloyds, NatWest, Santander UK, Metro Bank, Starling, Monzo Business, Tide, Revolut Business, Wise Business, or any other.

Recommended — sales invoices for the period (especially for zero-rated exports and reverse charge services), purchase invoices for any input VAT claim above GBP 250, the client's VAT registration number (9-digit GB number), the prior period's VAT return (for Box 5 reconciliation and FRS comparison).

Ideal — complete invoice register, MTD-compatible digital records with digital links, reconciliation of prior period Box 5 position, confirmation of VAT scheme (standard, FRS, cash accounting, annual accounting).

Refusal policy if minimum is missing — SOFT WARN. If no bank statement is available at all, hard stop. If bank statement only without invoices, proceed but record in the reviewer brief: "This VAT100 was produced from bank statement alone. The reviewer must verify, before approval, that input VAT claims above GBP 250 are supported by compliant tax invoices and that all reverse-charge classifications match the supplier's invoice."

UK-specific refusal catalogue

These refusals apply on top of any universal refusals in vat-workflow-base. If any trigger fires, stop, output the refusal message verbatim, end the conversation. Refusal is a safety mechanism.

R-UK-1 — Partial exemption beyond de minimis. Trigger: client makes both taxable and exempt supplies and the exempt input VAT exceeds GBP 625 per month on average OR exceeds 50% of total input VAT. Message: "Your exempt input VAT exceeds the de minimis threshold. Partial exemption requires a formal calculation under the standard method (or a special method agreed with HMRC) including an annual adjustment. This is too fact-sensitive for this skill. Please use a qualified accountant (ACA/ACCA/CTA) to determine and confirm the recoverable proportion before input VAT is claimed."

R-UK-2 — Transfer of a going concern (TOGC). Trigger: the period contains a business transfer that may qualify as a TOGC under VATA 1994 s49. Message: "TOGCs are outside the scope of VAT but have strict conditions. Incorrect treatment can result in a significant VAT liability. Please use a qualified accountant to confirm TOGC status."

R-UK-3 — Margin scheme (second-hand goods, tour operators). Trigger: client deals in second-hand goods under the margin scheme or is a tour operator using TOMS. Message: "Margin scheme transactions require transaction-level margin computation. Tour Operators' Margin Scheme (TOMS) requires a year-end calculation. Out of scope for this skill."

R-UK-4 — CIS reverse charge complex. Trigger: the client receives or makes supplies of construction services within the Construction Industry Scheme where the end-user exemption, intermediary supplier status, or mixed supply classification is unclear. Message: "The CIS domestic reverse charge is fact-specific. End-user exemptions, intermediary supplier status, and mixed supply classification require professional judgement. Please confirm with a qualified accountant before applying or disapplying the reverse charge."

R-UK-5 — VAT group. Trigger: client is part of a VAT group or asks about group registration under VATA 1994 s43. Message: "VAT groups require consolidation across all group members. Intra-group supplies are disregarded. Out of scope for this skill."

Section 3 — Supplier pattern library (the lookup table)

This is the deterministic pre-classifier. When a transaction's counterparty matches a pattern in this table, apply the treatment from the table directly. Do not second-guess. Do not consult Tier 1 rules — the table is authoritative for patterns it covers.

How to read this table. Match by case-insensitive substring on the counterparty name as it appears in the bank statement. If multiple patterns match, use the most specific. If none match, fall through to Tier 1 rules in Section 5.

Post-Brexit note. Since 1 January 2021, EU suppliers are treated identically to non-EU suppliers for UK VAT purposes. There is no intra-EU acquisition regime for the UK. Services received from both EU and non-EU suppliers trigger the reverse charge under the same rules. Goods imported from any country (including EU) are subject to import VAT (postponed or at border).

3.1 UK banks (fees exempt — exclude)

3.2 HMRC and government (exclude entirely)

3.3 UK utilities

3.4 UK insurance (exempt — exclude)

3.5 UK transport

3.6 UK food and entertainment

3.7 SaaS — EU suppliers (reverse charge, Box 6/7)

Post-Brexit, EU suppliers are treated as overseas suppliers. Services received from EU-established businesses trigger the reverse charge. The UK recipient self-accounts: output VAT in Box 1 (and Box 6 for the net value), input VAT in Box 4 (and Box 7 for the net value). Net cash effect zero for a fully taxable business.

3.8 SaaS — non-EU suppliers (reverse charge, Box 6/7)

Post-Brexit, both EU and non-EU suppliers trigger the same reverse charge mechanism. The distinction is academic for UK VAT purposes but listed separately for clarity of billing entity.

3.9 Payment processors (fees exempt — exclude)

3.10 Professional services (UK domestic 20%)

3.11 Property and rent

3.12 Payroll and statutory payments (exclude entirely)

Section 4 — Worked examples

These are six fully worked classifications drawn from a hypothetical bank statement of a UK-based self-employed IT consultant. They illustrate the trickiest cases. Pattern-match against these when you encounter similar lines in any real statement.

Example 1 — Overseas SaaS reverse charge (Notion)

Input line: 03.04.2025 ; NOTION LABS INC ; DEBIT ; Monthly subscription ; USD 16.00 ; GBP 12.80

Reasoning: Notion Labs Inc is a US entity (Section 3.8). No VAT on the invoice. This is a service received from an overseas supplier. The UK recipient self-accounts for VAT under the reverse charge. Output VAT goes to Box 1 (GBP 2.56 = 12.80 x 20%) and Box 6 (GBP 12.80 net). Input VAT goes to Box 4 (GBP 2.56) and Box 7 (GBP 12.80 net). Net cash effect zero for a fully taxable business.

Output:

Example 2 — EU service, reverse charge post-Brexit (Google Ads)

Input line: 10.04.2025 ; GOOGLE IRELAND LIMITED ; DEBIT ; Google Ads April 2025 ; -850.00 ; GBP

Reasoning: Google Ireland Limited is an IE entity. Post-Brexit, Ireland is overseas for UK VAT purposes — same treatment as any non-UK supplier. Reverse charge applies. Output VAT = GBP 170.00 (850 x 20%) to Box 1. Net GBP 850 to Box 6. Input VAT GBP 170.00 to Box 4. Net GBP 850 to Box 7. Net cash effect zero.

Output:

Example 3 — Client entertainment, fully blocked

Input line: 15.04.2025 ; THE IVY RESTAURANT LONDON ; DEBIT ; Business dinner ; -220.00 ; GBP

Reasoning: Restaurant transaction. Client entertainment input VAT is fully blocked under VATA 1994 s25 and the VAT (Input Tax) Order 1992. Unlike some jurisdictions, the UK has no partial recovery for business meals with clients. The one exception: entertaining overseas customers IS recoverable. Default: full block unless confirmed overseas customer entertainment. The net value still goes to Box 7, but no VAT to Box 4.

Output:

Example 4 — Domestic fuel (5% reduced rate)

Input line: 18.04.2025 ; BRITISH GAS ; DEBIT ; Direct debit gas bill ; -95.00 ; GBP

Reasoning: Domestic fuel and power attracts the 5% reduced rate. If this is the client's home and they work from home, only the business-use proportion is recoverable. Default: 0% business use unless the client specifies a proportion. The gross amount includes 5% VAT: net = 95.00 / 1.05 = GBP 90.48, VAT = GBP 4.52.

Output:

Example 5 — Zero-rated export sale

Input line: 22.04.2025 ; ACME CORP INC NEW YORK ; CREDIT ; Invoice UK-2025-018 IT consultancy March ; +5,000.00 ; GBP

Reasoning: Incoming payment from a US company. B2B services to an overseas customer — place of supply is the customer's country (US) under the general rule. The client invoices at 0% (outside the scope of UK VAT). Report net amount in Box 6 (total outputs). No output VAT in Box 1. Confirm: (a) customer is a business, not a consumer; (b) the invoice shows no UK VAT with a note that the supply is outside the scope of UK VAT.

Output:

Example 6 — Flat Rate Scheme computation

Input line: Quarter total: gross (VAT-inclusive) turnover GBP 30,000. FRS sector: IT consultancy (14.5%). Goods purchased in quarter: GBP 200.

Reasoning: First check the Limited Cost Trader test. Goods spend = GBP 200. 2% of GBP 30,000 = GBP 600. GBP 200 < GBP 600, and GBP 200 < GBP 1,000 annualised. Client IS a Limited Cost Trader. Rate = 16.5%, not 14.5%. VAT payable = 30,000 x 16.5% = GBP 4,950. Under standard accounting: output VAT = GBP 5,000 (30,000 / 1.2 x 0.2), input VAT recovery would need to exceed GBP 50 to beat FRS. At 16.5% LCT, FRS is almost certainly worse than standard accounting. Flag for reviewer.

Section 5 — Tier 1 classification rules (compressed)

Each rule states the legal source and the box mapping. Apply silently if the data is unambiguous. For full doctrinal context, see the source citations in Section 10.

5.1 Standard rate 20% (VATA 1994 s2(1), Schedule 7A)

Default rate for any taxable supply unless a reduced rate, zero rate, or exemption applies. Most goods and services, professional fees, software, electronics, commercial property (where opted to tax). Sales output VAT to Box 1. Net sales to Box 6. Purchase input VAT to Box 4. Net purchases to Box 7.

5.2 Reduced rate 5% (VATA 1994 Schedule 7A)

Applies to: domestic fuel and power (gas, electricity for domestic use), children's car seats, energy-saving materials installed in residential property, smoking cessation products, contraceptive products, women's sanitary products (from January 2021). Purchases at 5%: extract VAT at 5/105 of the gross. Box 7 for net, Box 4 for input VAT (subject to business-use proportion for home office).

5.3 Zero rate 0% (VATA 1994 Schedule 8)

Applies to: most food (not catering, not hot takeaway, not confectionery, not alcohol, not soft drinks), children's clothing and footwear, books and newspapers (print and digital since May 2020), public transport fares, new residential construction (first grant of a major interest), exports of goods, prescribed medicines, water supply. Sales: no output VAT, but net value goes to Box 6. Purchases: no input VAT to claim, but net value goes to Box 7. Input VAT on costs attributable to zero-rated supplies IS recoverable.

Key rate traps:

5.4 Exempt supplies (VATA 1994 Schedule 9)

No VAT charged, no input VAT recovery on attributable costs. Exempt supplies: insurance, financial services (interest, foreign exchange, securities dealing), education (by eligible bodies), health services (by registered practitioners), burial and cremation, postal services (Royal Mail universal service), land and property (unless opted to tax), membership subscriptions (certain professional bodies), betting and gaming.

If exempt supplies are significant, partial exemption rules apply — R-UK-1 refuses if beyond de minimis.

5.5 Outside scope (exclude from all boxes)

Wages, salaries, dividends, donations, non-business activities, statutory fees (road tax, council tax, business rates), HMRC tax payments, loan principal, drawings, internal transfers. Do NOT include in Box 6 or Box 7.

5.6 Reverse charge — services received from overseas suppliers

Post-Brexit, all non-UK suppliers (whether EU or non-EU) trigger the same reverse charge mechanism for services. The UK recipient self-accounts at 20%: output VAT to Box 1, net value to Box 6; input VAT to Box 4, net value to Box 7. Net cash effect zero for a fully taxable business. If the overseas supplier incorrectly charged their local VAT (e.g. Irish 23%), that foreign VAT is NOT recoverable as UK input tax — treat as a cost.

5.7 Reverse charge — CIS construction (VATA 1994 s55A)

For specified construction services between VAT-registered, CIS-registered businesses where the customer makes onward supplies of construction services: the customer (not the supplier) accounts for VAT. Supplier invoices net with annotation "Reverse charge: Customer to account to HMRC for VAT on this supply." Customer: output VAT to Box 1, input VAT to Box 4, net value to Box 7 only (not Box 6 — this is the customer's input, not output). End-user exemption: does NOT apply if the customer is an end user or intermediary supplier.

5.8 Input VAT — blocked categories (VATA 1994 s25; VAT (Input Tax) Order 1992)

The following input VAT CANNOT be reclaimed:

• Business entertainment: entertaining UK customers, suppliers, or other business contacts. Exception: entertaining overseas customers IS recoverable
• Motor cars: VAT on purchase or lease of cars NOT exclusively for business use. Exception: 100% business use (pool car, driving instructor car, taxi) = fully recoverable
• Car fuel (private element): if car has any private use, full input VAT on fuel is blocked UNLESS the fuel scale charge is applied
• Non-business expenditure: expenditure not wholly for business purposes

Partially recoverable items:

• Mobile phones: fully recoverable if business contract (even if some private use)
• Home office costs: apportion business vs private — recover business element only
• Mixed-use equipment: apportion on reasonable basis

5.9 Bad debt relief (VATA 1994 s36; VAT Regulations 1995 reg 168-172)

If a customer does not pay, the supplier can reclaim the output VAT already paid to HMRC. Conditions: debt at least 6 months old (from later of due date or supply date), debt written off in accounts, claim on VAT return for the period conditions are met, claim within 4 years 6 months of supply date. Relief amount added to Box 4. If customer later pays, relief must be reversed.

5.10 Flat Rate Scheme (VATA 1994 s26B)

Business charges 20% on invoices, pays HMRC a flat percentage of gross (VAT-inclusive) turnover. Key rule: ALWAYS run the Limited Cost Trader test first. If goods spend < 2% of gross turnover (or < GBP 1,000/year if greater), rate is 16.5% regardless of sector. "Relevant goods" excludes: capital goods over GBP 2,000, food/drink for staff, vehicles/fuel/vehicle parts. Under FRS, input VAT on capital goods costing GBP 2,000 or more (incl. VAT) CAN be reclaimed separately in Box 4.

5.11 Cash accounting scheme (VAT Regulations 1995 reg 56-65)

Account for VAT based on date of payment, not invoice date. Entry: estimated taxable turnover <= GBP 1,350,000. Exit: GBP 1,600,000. Built-in bad debt relief — no output VAT due on unpaid invoices.

5.12 Filing deadlines and penalties (Finance Act 2021, from Jan 2023)

Late submission: points-based. Quarterly filers: penalty threshold at 4 points (GBP 200 per late return once threshold reached). Points expire after 12 months of compliance. Late payment: no penalty for 1-15 days late; 2% of outstanding VAT at day 16-30; additional 2% at day 31+ plus daily rate of 4% per annum. Late payment interest: Bank of England base rate + 2.5%.

5.13 MTD requirements (all VAT-registered businesses since April 2022)

Must keep digital records, maintain digital links between software systems (no manual re-keying), and file via MTD-compatible software. HMRC's basic online portal is NOT compliant with MTD.

Section 6 — Tier 2 catalogue (compressed)

For each ambiguity type: pattern, why the bank statement is insufficient, conservative default, question for the structured form.

6.1 Vehicle costs (fuel — business or private?)

Pattern: BP, SHELL, ESSO, TEXACO, TESCO FUEL, ASDA FUEL, fuel receipts. Why insufficient: vehicle type and business-use proportion unknown. If car with any private use → fuel input VAT blocked unless fuel scale charge applied. If van or commercial vehicle used exclusively for business → fully deductible. Default: 0% recovery. Question: "Is this fuel for a car (with private use — blocked) or a commercial vehicle used exclusively for business? Do you apply the fuel scale charge?"

6.3 Home office (electricity/gas — 5% domestic rate, but what % is office?)

Pattern: energy supplier names, BRITISH GAS, EDF, OCTOPUS, etc. Why insufficient: business proportion unknown. Domestic fuel is 5% VAT, but only the business-use percentage is recoverable. Default: 0% if mixed use without declared proportion, 100% if confirmed dedicated business premises. Question: "Is this a home office or a dedicated business premises? If home office, what percentage of the property is used exclusively for business? (Typical range: 10-25%)"

6.5 Amazon/eBay (business or personal?)

Pattern: AMAZON, AMAZON.CO.UK, AMAZON MARKETPLACE, AMZN, EBAY. Why insufficient: could be business stock/supplies or personal purchases. Amazon UK charges 20% VAT on most items. Default: block (personal). Question: "Was this a business purchase? If so, what was bought and do you have a VAT invoice?"

6.6 Mobile phone (business % unknown)

Pattern: VODAFONE, EE, THREE, O2, GiffGaff, MOBILE. Why insufficient: if the contract is in the business name, full input VAT is recoverable even with some private use. If personal contract used partly for business, only business proportion is recoverable. Default: 0% recovery (personal contract assumed). Question: "Is this a business contract in the business name, or a personal phone used for business?"

6.7 FRS Limited Cost Trader test (did goods spend exceed 2%?)

Pattern: any FRS client. Why insufficient: bank statement shows total spend but not whether individual purchases are "relevant goods" vs services/excluded items. Default: LCT at 16.5% (most conservative). Question: "For the FRS Limited Cost Trader test: how much did you spend on goods (physical items used exclusively for business, excluding capital goods over GBP 2,000, food/drink for staff, vehicles/fuel/vehicle parts) this quarter?"

6.8 Round-number incoming transfers from owner-named counterparties

Pattern: large round credit from a name matching the client's name. Why insufficient: could be a customer sale, owner injection, or family loan. Default: exclude as owner injection. Question: "The GBP X transfer from [name] — is this a customer payment, your own money going in, or a loan?"

6.9 Incoming transfers from individual names (not owner)

Pattern: incoming from private-looking counterparties. Why insufficient: could be B2C sale, B2B sale paid from personal account, refund. Default: domestic B2C sale at 20%, Box 6/1. Question: "For each: was it a sale? Business or consumer customer?"

6.11 Rent payments

Pattern: monthly RENT, LEASE to a landlord-sounding counterparty. Why insufficient: commercial vs residential, whether landlord has opted to tax. Default: no VAT, no deduction (residential default). Question: "Is this a commercial property? Does the landlord charge VAT on the rent (they will only charge VAT if they have opted to tax the property)?"

6.12 Foreign hotel and accommodation (non-UK)

Pattern: hotel or accommodation charged abroad. Why insufficient: place of supply is the location of the property — non-UK VAT paid at source, not recoverable as UK input tax. Default: exclude from input VAT. Question: "Was this a business trip?" (For income tax records, the expense may still be deductible.)

6.13 Platform sales (Amazon Seller, eBay, Etsy)

Pattern: incoming from Amazon Payments, Etsy Payments, PayPal, Stripe — settlement payouts. Why insufficient: aggregated settlement may include multi-country buyer mix. Default: treat gross as Box 6/1 at 20%. Platform fees as separate reverse charge (IE/US entity). Question: "Do you sell to buyers outside the UK? Total overseas sales for the year? Do you sell on Amazon EU marketplaces?"
