FRS 105 vs FRS 102: The Reporting Standard Decision

1. The UK GAAP Landscape

UK Generally Accepted Accounting Practice, UK GAAP, offers small companies two realistic paths: FRS 105 for micro-entities and FRS 102 (Section 1A) for small entities. A third route, full FRS 102, is mandatory for medium-sized entities. IFRS remains an option for any company but is practically only used by listed or internationally-oriented groups.

The choice between FRS 105 and FRS 102 Section 1A is not simply "small company vs tiny company". It is a choice about how much of the company's financial position to show the world, and therefore about how creditworthy the company appears, how painful future due diligence becomes, and how flexible the accounting policies can be.

2. FRS 105, The Micro-Entity Standard

FRS 105 is the simplest UK GAAP standard. A company qualifies as a micro-entity if it meets two of three thresholds: turnover <= £1m, balance sheet total <= £500k, and average employees <= 10. The vast majority of one-director limited companies comfortably qualify.

The standard sacrifices disclosure for simplicity. Filed accounts need only a balance sheet with minimal notes, no profit and loss filing requirement, no directors' report, no cashflow statement, and no requirement to revalue assets at fair value. The accounts presented to HMRC (with the CT600) must include a profit and loss account, but the version filed at Companies House does not.

FRS 105 also restricts accounting policy choice. Revaluation of fixed assets to fair value is prohibited, everything must be held at historical cost less depreciation. Development costs cannot be capitalised. Deferred tax is not recognised. These are simplifications, but they can understate the company's economic reality.

3. FRS 102 Section 1A, Small Entities

FRS 102 is the main body of UK GAAP for small, medium, and large entities not using IFRS. Section 1A is a reduced-disclosure regime for entities that qualify as small: two of (a) turnover <= £15m, (b) balance sheet <= £7.5m, (c) employees <= 50.

Section 1A permits substantially richer accounting policies than FRS 105. Investment property can be fair-valued through profit and loss. Development expenditure can be capitalised. Deferred tax is recognised. Financial instruments can be measured at fair value. These policy choices produce accounts that more accurately reflect the underlying economics of a trading business.

The trade-off is disclosure. Section 1A accounts include a profit and loss account, directors' report, and a more detailed notes section covering related-party transactions, financial commitments, employee numbers, director remuneration, and accounting policies. The accounts run longer, take longer to prepare, and reveal more.

4. Side-by-Side Comparison

• Turnover limit: FRS 105 £1m vs FRS 102 Section 1A £15m.
• Profit and loss filed publicly: FRS 105 no; Section 1A yes.
• Fair value accounting: FRS 105 no; Section 1A yes.
• Deferred tax: FRS 105 no; Section 1A yes.
• Development cost capitalisation: FRS 105 no; Section 1A yes.
• Director remuneration disclosure: FRS 105 minimal; Section 1A more detailed.
• Preparation cost: FRS 105 lower; Section 1A higher.

5. Creditworthiness and Lender Perception

Credit reference agencies, Experian, Equifax, Creditsafe, Dun & Bradstreet, score UK companies primarily on filed accounts. Micro-entity accounts give the agencies less to work with. A healthy trading business filing under FRS 105 often receives a lower credit score than the same business would under Section 1A, because the agency cannot see the profit and loss account to validate that trading is actually profitable.

This matters when applying for trade credit, commercial mortgages, invoice finance, or asset finance. Many lenders refuse to quote against micro-entity accounts at all, or require supplementary management accounts to supplement the filed set. If your business borrows or hopes to borrow, micro-entity disclosure is a strategic disadvantage.

6. Investor and Acquirer Readiness

Serious investors and acquirers conduct due diligence against management accounts, not filed accounts, but they also examine the filed history for consistency. A business that has filed micro-entity accounts for five years before attempting a fundraise cannot retrospectively produce a credible financial narrative.

The practical recommendation: if fundraising or a future sale is plausible within three to five years, file Section 1A accounts now. The marginal preparation cost is trivial compared with the due diligence friction created by a sudden switch from FRS 105 to Section 1A in the year of the transaction.

7. Switching Between Standards

A company can move from FRS 105 to FRS 102 Section 1A whenever the directors choose, no approval is required, and no "minimum period" applies. The transition requires restatement of opening balances under the new standard, which usually surfaces small adjustments for deferred tax and, if relevant, fair-value movements.

Moving from Section 1A back to FRS 105 is permitted but unusual. More common is a forced move: once a company exceeds micro-entity thresholds (turnover £1m, balance sheet £500k, 10 employees) for two consecutive years, FRS 105 is no longer available and the company must file under Section 1A or higher. Growing businesses should plan the transition proactively rather than discovering it at year-end.
