UK GAAP is changing: Why business owners should act before the numbers change

Most business owners will not lose sleep over accounting standards. But the UK GAAP changes introduced in 2026 are worth paying attention to.

If your business reports under FRS 102, the amendments could change how revenue is recognised, how leases appear in the accounts and what small companies need to disclose. That may sound like an accounting issue. In practice, it can become a business issue quite quickly.

Why? Because the underlying business may not have changed, but the numbers people use to assess it might. Profit, EBITDA, debt, reserves and financial ratios could all look different. That matters if your bank, shareholders, future buyer or tax adviser is relying on those figures.

So, the question for business owners is not just “what is changing?” It is “what could this mean for my business before the accounts are signed?”

Below, we explain the key changes and steps you can take to ensure your business complies with the 2026 FRS102 amendments.

 

WHAT IS CHANGING UNDER UK GAAP?

For those businesses reporting under FRS 102, the amendments introduce:

• A new five-step model for revenue recognition based on IFRS 15
• New lease accounting rules broadly aligned with IFRS 16
• Additional disclosure requirements for some businesses
• Updates affecting tax disclosures, related parties, business combinations and other reporting areas

The amendments to UK GAAP apply for accounting periods beginning on or after 1 January 2026. For many companies, the first affected accounts may not be prepared until 2027, but the transition date could be much earlier. That means businesses should start assessing the impact now, rather than waiting until the accounts are due.

 

AMENDMENTS TO FRS102 AND THEIR IMPACT ON YOUR BUSINESS

1. REVENUE RECOGNITION

FRS 102 is moving closer to the approach in IFRS 15, with a five-step revenue model for contracts with customers. The detail is technical, but the core idea is straightforward: what has the business promised to deliver, what is the price for those promises, and when have those promises been fulfilled?

For simple sales of goods, there may be little change. But areas that need more thought are usually arrangements such as:

• long-term contracts or staged project work;
• bundled goods and services;
• subscriptions, retainers or ongoing support arrangements;
• deposits, milestone payments or performance-based fees;
• rebates, discounts, variable pricing or contract changes.

The practical issue is timing. Some businesses may recognise revenue earlier than before; others may recognise it later. Either way, year-on-year profit trends may need explanation.

 

2. LEASE ACCOUNTING

Lease accounting is also moving closer to IFRS 16, with some simplifications. Many leases that previously sat off the balance sheet will now be recognised as a right-of-use asset and a lease liability.

There are exemptions for certain short-term leases and low-value assets, but it is worth checking before assuming the changes will not apply.

Whilst the lease payments themselves may not change, the accounts can. Operating lease rentals may be replaced by depreciation and interest charges. That can move EBITDA, operating profit, liabilities, gearing and other measures used by lenders and stakeholders.

 

3. SMALL COMPANY DISCLOSURES AND OTHER CHANGES

Revenue and leases will get most of the attention, but they are not the only changes. Small companies applying FRS 102 Section 1A should also expect more disclosure than before where the information is relevant and material.

One important example for owner-managed companies is dividends. Revised Section 1A introduces disclosure requirements for dividends declared, paid or payable during the reporting period. That matters because dividends are often central to how owner-managers extract value from the business.

Other areas may also need attention, including tax disclosures, related party disclosures, share-based payments, leasing disclosures, revenue performance obligations, fair value measurement, uncertain tax positions, business combinations and, in some cases, software cost classification.

 

IMPACTS OF THE CHANGES TO UK GAAP

The commercial impact may be more important than the accounting language. These changes can affect how people outside the business read the accounts. Below we explain the specific impact changes to UK GAAP could have on different areas of your accounts.

BANKING COVENANTS AND FUNDING

Revenue recognition changes and leases coming onto the balance sheet can affect covenant calculations. Lease liabilities may increase reported debt or gearing. Revenue timing may affect profit, EBITDA or interest cover.

That does not mean every business will have a problem. But if a bank facility uses accounting numbers, it is sensible to check the definitions and headroom early. It is much easier to explain an accounting change before it becomes a covenant conversation.

 

DIVIDENDS AND DISTRIBUTABLE RESERVES

For many owner-managed companies, dividends are not an afterthought – they are part of the financial plan. If the new rules affect reported profits, reserves or transition adjustments, they may also affect how directors assess distributable profits.

The key point is not that dividends will automatically be restricted. It is that directors should understand the impact before dividends are declared or paid, and make sure the supporting records are clear.

 

TAX TIMING AND CASHFLOW

The changes may not alter the total tax paid over the life of a contract or lease, but they can affect timing. If revenue is recognised earlier, taxable profits may also come through earlier. If lease accounting changes the expense profile, tax and deferred tax positions may need review.

For growing businesses, there may also be cashflow points to consider, including tax forecasts and whether quarterly instalment payments could become relevant.

 

AUDIT THRESHOLDS AND COMPANY SIZE

Bringing lease assets and liabilities onto the balance sheet may increase reported gross assets and liabilities. For companies close to size thresholds, that could affect reporting requirements and audit exemption considerations.

This is one of the more practical points for smaller and growing businesses. The business may feel the same day to day, but the balance sheet may not look the same.

 

BUSINESS SALES, ACQUISITIONS AND VALUATIONS

If a sale, acquisition, management buyout, fundraising or succession plan is on the horizon, the changes should be considered early. Buyers and funders often focus on EBITDA, net debt, working capital, revenue quality and profit trends.

If those measures move because of UK GAAP, the business will need a clear explanation. Addressed early, this can help present a more transparent and consistent financial picture. Left until due diligence, it can create extra questions at the wrong time.

 

DO CHANGES TO UK GAAP AFFECT YOUR BUSINESS?

The answer is ‘possibly’. The only sensible way to know is to review your contracts, leases and reporting requirements. The changes are more likely to need attention where a business has:

• property, vehicle, equipment or machinery leases;
• long-term contracts, staged work or projects delivered over time;
• bundled services, subscriptions, support packages or retainers;
• variable fees, rebates, discounts, milestones or performance-based pricing;
• bank covenants, external investors, earn-outs or planned M&A activity;
• regular dividends paid to owner-managers;
• small company accounts prepared under FRS 102 Section 1A.

 

A practical point

Even if the conclusion is that the changes are not material, it is still worth documenting that assessment. “No significant impact” is much easier to support when the business has actually reviewed the relevant contracts, leases and disclosures.

 

Smaller changes owner-managed businesses should not overlook

Not every business will have complex revenue contracts or large property leases. But many owner-managed companies will still see changes in the detail of their accounts.

Area	Why it matters
Related party disclosures	More detailed related party information may be needed. This is relevant where directors, shareholders or connected businesses transact with the company.
Tax disclosures	Small company accounts may include more detail on tax and deferred tax, so the year-end tax position may need more explanation.
Management accounts	If internal reporting keeps using the old basis, owners may be looking at a different profit picture internally from the one in the statutory accounts.

ACTIONS BUSINESS OWNERS CAN TAKE NOW AS YOU PREPARE FOR FRS102 AMENDMENTS

The good news is that preparation does not need to become a major project for every business. But preparation should not be left until the accounts are being finalised. A sensible starting point is:

List your leases, include:

• Property leases
• Vehicle leases
• Plant and equipment leases

Lease arrangements hidden inside service contracts

Review key customer contracts, pay particular attention to

• Staged projects
• Long-term work
• Subscription arrangements
• Variable-pricing arrangements

Model the likely impact on:

• Profit
• EBITDA
• Net assets
• Gearing
• Tax
• Reserves
• Covenants

 

1. Check agreements that use accounting numbers – including bank facilities, shareholder agreements, earn-outs, bonus schemes and dividend plans.
2. Review management accounts and KPIs – so internal reporting stays useful and comparable.
3. Check whether systems hold the right data – particularly lease terms, discount rates, contract obligations and disclosure information.
4. Document the conclusion – including where the expected impact is limited.

 

FINAL THOUGHTS

The 2026 UK GAAP changes should not be treated as a year-end compliance exercise. For many owner-managed businesses, they are a prompt to look again at contracts, leases, reporting, funding arrangements and dividend planning.

Businesses that prepare early will be in a better position to avoid surprises, explain their numbers clearly and make decisions using information they trust.
