HMRC Updates Flat Rate Scheme Notice 733

HMRC has recently updated Flat Rate Scheme Notice 733. The main revisions focus on how to select the correct sector rate under the VAT Flat Rate Scheme.

Previously, paragraph 4.4 was dedicated to “business activities that are the source of common enquiry.” It advised that if you act as a consultant and don’t fit into another specific sector, you should choose “management consultancy” (14%). This applied even if you weren’t a traditional management consultant. It effectively ruled out choosing “any other activity not listed elsewhere” at the lower 12% rate.

Tribunal Disputes and HMRC Guidance

The guidance listed “architect, civil and structural engineers” to include engineering consultants and designers. This became the area of dispute in two First-tier Tribunal cases: IDESS Ltd (TC03638) and SLL Subsea Engineering Ltd (TC04256).

HMRC’s changes to Notice 733 came after the Association of Taxation Technicians (ATT) urged HMRC to revise its guidance, stating it misrepresented court findings.

IDESS Ltd (TC03638)

IDESS Ltd operated in mechanical engineering within the nuclear industry. After reviewing the company’s records, HMRC decided that the business should have been using the 14.5% rate for “architect, civil and structural engineer.” They issued an assessment and penalties.

The Tribunal disagreed. It found the company was not an architect, civil, or structural engineer. It performed maintenance and repair of machinery, not buildings. Therefore, HMRC’s assumption that all engineers should use the 14.5% rate was incorrect and contrary to the law.

SLL Subsea Engineering Ltd (TC04256)

In SLL Subsea Engineering Ltd, the Tribunal also ruled against HMRC. It decided HMRC had been unreasonable in reversing the taxpayer’s choice of flat rate sector. HMRC relied too heavily on its own guidance rather than the legislation itself.

The judgment stated: “Paragraph 4.4 cannot extend the meaning of the 1995 Regulations. The fact that HMRC think that any engineering design or consultancy work falls into their chosen category does not change the ambit of that category at all.”

Key Legal Implications

These two cases highlight an important principle — HMRC guidance and the law are not always identical. Taxpayers may assume they are, but the courts confirmed that guidance cannot override legislation.

Selecting the Correct Flat Rate Sector

When joining the VAT Flat Rate Scheme, start by checking the official list of categories in the 1995 VAT Regulations, SI 1995/2518, Regulation 55K. This list is also linked in Notice 733 (paragraph 4.3). Each description should be interpreted using its ordinary meaning.

Areas of Doubt

If your business does not fit neatly into any category, HMRC provides guidance in the Flat Rate Scheme Manual at FRS7200 and FRS7300. These paragraphs, referenced in section 4.1 of the Notice, now reflect the latest court decisions.

Documenting Your Decision

When choosing your sector rate, record the reasoning behind your choice. If you can demonstrate that your selection was reasonable, HMRC will find it difficult to challenge it retrospectively.

Example Case: Vintage Tea House Ltd (TC03160)

This principle was demonstrated in Vintage Tea House Ltd, where the taxpayer appealed against HMRC’s attempt to backdate an assessment. HMRC had reversed the company’s decision to use the lower rate for “retailing not listed elsewhere” instead of the higher rate for “catering services including restaurants and takeaways.”

Why the Decision Was Reasonable

The business sold teapots, mugs, novelty items, and provided about ten seats for customers to enjoy light refreshments. The Tribunal found the taxpayer’s original choice reasonable. Their lease limited the premises to “the sale of home and garden accessories, with ancillary sale of cakes, sandwiches, pastries, etc.” There was also no ventilation for an oven.

When the Rate Should Have Changed

However, the appeal was only partially successful. The Tribunal ruled the company should have reviewed its sector annually. When the teashop expanded to 28 seats and food sales became the predominant source of turnover, it should have switched to the catering sector rate.

FAQ: VAT Flat Rate Scheme and Notice 733

What is the VAT Flat Rate Scheme?

The VAT Flat Rate Scheme is a simplified way for small businesses to calculate their VAT. Instead of working out VAT on every transaction, you pay a fixed percentage of your relevant turnover to HMRC. This percentage depends on your business sector, as outlined in VAT Notice 733.
Relevant turnover refers to your total business income that is subject to VAT. This includes most sales where you include VAT in your pricing. It excludes certain items like capital asset sales or income outside the scope of VAT.
Yes, your flat rate turnover should include VAT. You calculate your VAT liability as a percentage of your gross turnover (including VAT), not your net sales.

VAT Notice 733 is HMRC’s official guidance for the VAT Flat Rate Scheme. It explains how to:

  • Choose your sector percentage
  • Calculate your VAT return
  • Understand relevant turnover and allowable costs
  • It is regularly updated to reflect legal changes and tribunal decisions.
The Changes to VAT Notice 733 (Jun 16, 2016) clarified how businesses should select their sector rate. Updates were influenced by tribunal cases and aimed to ensure HMRC guidance aligns more closely with legislation rather than interpretation.

From April 2017, following announcements around March 2017, HMRC introduced rules for “limited cost businesses.” These changes affect how much you spend on relevant goods:

  • If your amount you spend on relevant goods is low, you may need to use a higher flat rate (16.5%)
  • This prevents businesses with minimal costs from gaining an unfair advantage

Spend on relevant goods refers to the cost of goods used exclusively for your business. It does not include:

  • Services
  • Capital expenditure
  • Food or drink for personal use

The amount you spend helps determine whether you qualify as a limited cost business.

Your VAT is calculated per accounting period. Each period starting date determines:

  • Which flat rate percentage applies
  • Whether new rules (such as April 2017 changes) affect your business
  • It is important to apply the correct rate for each VAT return period.

When completing your VAT return, you:

  1. Calculate your flat rate turnover (including VAT)
  2. Apply your sector percentage
  3. Pay that amount to HMRC

You cannot usually reclaim VAT on purchases, except for certain capital assets.

You should:

  • Refer to the sector list in VAT Notice 733
  • Use the definitions in the 1995 VAT Regulations
  • Base your decision on your main business activity

If unsure, review HMRC manuals or document your reasoning to support your choice.

Tribunal cases show that HMRC guidance does not override the law. If your decision is reasonable and well documented, HMRC may find it difficult to challenge your choice retrospectively.

Your business activities can change over time. As seen in tribunal cases, if your income shifts (for example, from retail to catering), your sector — and therefore your flat rate — may also need to change. Regular reviews help ensure compliance.
