FRS 102 UK GAAP: Complete Guide to 2026/27 Amendments & Small Entities Relief

FRS 102 (The Financial Reporting Standard applicable in the UK and Republic of Ireland) is the primary GAAP standard for UK-registered entities not qualifying for IFRS. It sits between IFRS (more complex) and the micro-entities regime (simpler). This guide covers scope, the Small Entities exemption, key differences from IFRS, and the 2026/27 amendments affecting UK-domiciled companies.

FRS 102 Scope and Status

FRS 102 has been the UK-adopted GAAP standard since January 2015 (replacing old UK GAAP). It's based on IFRS for SMEs but incorporates additional UK-specific requirements and disclosure concessions for smaller entities.

Current status (2026): FRS 102 remains the standard for UK companies not required to report under IFRS. The FCA requires IFRS for listed companies; unlisted entities use FRS 102 unless they are micro-entities (FRS 105).

Who Applies FRS 102?

Mandatory FRS 102 Users

Private companies: Most UK private companies (by definition, unlisted)
Public unlisted companies: UK-listed entities NOT on the Premium segment (often use IFRS, but could choose FRS 102)
Charities: Many charities use FRS 102 (though some follow Charities SORP)
Large unlisted groups: May voluntarily adopt FRS 102 unless group consolidated over thresholds

Exemptions

Micro-entities (FRS 105): Turnover <£6.5m, assets <£3.26m, employees <10 (small entity exemption available)
Listed entities: Must use IFRS (FCA requirement for premium listing)
Banking/insurance: Specific sector standards may override

Small Entities Exemption (SE Regime)

FRS 102 includes significant disclosure and measurement reliefs for entities meeting size thresholds:

Qualification Thresholds (2 of 3)

Turnover ≤ £10.2m (previously £8.8m; increased 2023)
Balance sheet assets ≤ £5.1m (previously £4.4m)
Employees ≤ 50

Small Entity Exemptions

Cash flow statement: Not required
Related party disclosures: Minimal (only key management)
Segmental reporting: Not required
Fair value measurements: Simplified (cost may be proxy; no fair value for investment property if no market)
Deferred tax: No recognition of DTA (simplifies provision estimates)

FRS 102 vs IFRS: Key Differences

1. Financial Instruments

Aspect	IFRS 9	FRS 102
Classification	SPPI test; business model test	Simpler: Available-for-Sale (AFS), Loans & Receivables, FVPL
Impairment	ECL model (3-stage; SICR triggers)	Simpler: Incurred loss model; indicators of impairment
Fair value option	FVPL allowed; strict criteria	FVPL more readily available for equities; AFS if no control

2. Leases (IFRS 16 vs FRS 102)

IFRS 16: All leases > 12 months capitalized as ROU assets
FRS 102: Operating vs finance lease distinction (narrower capitalization)

3. Property Revaluation

IFRS: Revaluation through OCI (or P&L); reversals matched by reversals
FRS 102: Revaluation through P&L (simpler); reversal to P&L only

FVPL Investments in FRS 102

FRS 102 permits more liberal use of FVPL for equity investments, especially when held as part of a trading portfolio or when fair value is readily available.

When FVPL is Permitted

Investments held for trading: Re-measured at fair value each period
Investments in associates (no significant influence): Can use FVPL instead of equity method
Financial liabilities: FVPL available for derivatives and fair value hedges

Fair Value Measurement

FRS 102 uses simpler fair value hierarchy (quoted prices > observable inputs > unobservable), but less detailed than IFRS 13.

FRS 102 2026/27 Amendments

Amendment 1: Lease Accounting Alignment

Ongoing harmonization with IFRS 16 principles (though full alignment may not occur; finance lease tests tightening).

Amendment 2: Climate-Related Disclosures

New guidance on climate risk disclosures (in line with UK TCFD requirements); applies to larger entities.

Amendment 3: Going Concern & Liquidity

Enhanced guidance on assessing going concern beyond 12 months and liquidity disclosures (especially post-pandemic volatility).

Transition from IFRS to FRS 102

Some entities (e.g., de-listing) move from IFRS to FRS 102. Key audit areas:

Asset Reclassifications

PP&E: Revaluation to cost-only (if using revaluation model under IFRS)
Investment property: Reclassification if no active market
Financial instruments: AFS/FVPL reclassification

Provision Adjustments

IFRS 37 restructuring provisions may not meet FRS 102 criteria (no liability if plan not finalized)
Deferred tax: May not be recognized (simplification)

Audit Red Flags: FRS 102 Conversions

Red Flag 1: IFRS Revaluations Not Reversed

Finding: Entity transitions from IFRS (used revaluation model for PP&E) to FRS 102 (cost model). Carrying values remain at revalued amounts without reversal.

Auditor action: Decide on deemed cost method (retain revalued amount as new cost) or actual reversal. Impact goodwill/impairment testing.

Red Flag 2: Investment Property Fair Value Estimates Unsupported

Finding: Investment property valued at £5m under IFRS (fair value hierarchy, market approach). Under FRS 102, no active market exists; valuation becomes cost-based, significantly lower.

Auditor action: Reassess fair value basis; if cost is more appropriate, write down; recognize impairment loss.

Red Flag 3: Provisions Overstated

Finding: Under IFRS, £10m restructuring provision recognized (IFRS 37, detailed plan). Transitioning to FRS 102, no finalized board approval for restructuring; FRS 102 does not require provision.

Auditor action: Reverse provision; adjust P&L; reclassify to contingent liability (if probable outflow).

Red Flag 4: Deferred Tax Not De-Recognized

Finding: Deferred tax of £3m (on temporary differences) carried forward from IFRS. FRS 102 micro/small entities exemption exempts DTA recognition.

Auditor action: Reverse DTA; adjust retained earnings; no tax expense adjustment (simplified).

Real-Life Case Study: A Company Reporting Under FRS 102

Scenario. A mid-sized UK manufacturer (turnover £30m) prepares its accounts under FRS 102, the main UK GAAP standard.

Key differences from IFRS it must manage. Goodwill and intangibles are amortised over a finite life (default up to 10 years if unreliable estimate) rather than impairment-only; development costs may be capitalised but need not be; and it takes the reduced disclosure regime available to qualifying entities. Investment property, though, is still at fair value through P&L, much like IFRS.

Takeaway. FRS 102 is "IFRS-lite" but not IFRS: the goodwill-amortisation difference alone changes the profit profile of any acquisitive group. Know which specific sections diverge before assuming an IFRS answer applies.
