Hello! I’m Zara, and I’m thrilled to welcome you to the official blog of my Cornwall-based business, Base2Base Bookkeeping.
Consider this your local hub for all things financial!
We dive into the latest bookkeeping news and provide straightforward guides to help you understand your accounts and keep your business running smoothly.




The start of a new financial year often brings a wave of updates, and 2025 is no exception. Chancellor Rachel Reeves delivered the Spring Statement 2025, confirming several key changes announced previously and outlining the fiscal path ahead. While perhaps lacking blockbuster announcements, the statement reinforces significant shifts impacting businesses of all sizes across Cornwall and the UK.
Understanding these changes is crucial for maintaining financial health and ensuring compliance.
At Base2Base Bookkeeping, we believe in empowering business owners with clarity and confidence.

Let’s break down the key takeaways from the Spring Budget 2025 and explore how they might affect your operations.

The Economic Backdrop: Setting the Scene

The Office for Budget Responsibility (OBR) has adjusted its UK economic growth forecast for 2025 downwards to 1.0%, reflecting ongoing global economic challenges. While inflation is expected to remain slightly above target through 2025, putting continued pressure on business costs, forecasts suggest a decline in 2026, potentially offering some relief.
On a positive note, real household disposable income is projected to see modest growth from the 2025/26 tax year onwards.
This mixed economic picture underscores the importance of careful financial planning and proactive management – areas where expert bookkeeping support can provide invaluable peace of mind.

Key Changes Impacting Businesses:

1 – Employment Costs: A Significant Shift

• Employer National Insurance (NI):

From 6th April 2025, the Employer NI rate increases from 13.8% to 15%. Furthermore, the threshold at which employers start paying NI (the Secondary Threshold) drops significantly from £9,100 per year to £5,000 per year. This means businesses will pay more NI for more employees, impacting payroll costs, especially for those with larger teams or in labour-intensive sectors.

• Employment Allowance:

To mitigate this, the Employment Allowance (which reduces eligible employers’ annual NI liability) increases from £5,000 to £10,500 from April 2025. Eligibility criteria have also been widened, removing the previous £100,000 upper limit. This is welcome news for many smaller businesses.

• National Living Wage (NLW) & National Minimum Wage (NMW):

As of 1st April 2025, the NLW (for workers 21+) rose to £12.21 per hour (a 6.7% increase). NMW rates for younger workers also increased substantially. While supporting employees, this adds to the pressure on overall wage bills.

How a Bookkeeper Helps:
Managing payroll is complex, and these changes add another layer. A bookkeeper ensures accurate calculations of NI and wages, administers the Employment Allowance correctly, keeps you compliant with NLW/NMW rates, and helps you budget effectively for these increased costs.

2 – Tax Compliance and Making Tax Digital (MTD)

• Increased HMRC Scrutiny:

HMRC is receiving more funding (£87 million for partnerships with private debt collectors) and staffing (500 new compliance officers, 600 debt management staff) to bolster tax compliance efforts. Expect closer monitoring of VAT, PAYE, and Corporation Tax records and submissions.

• Stricter Penalties:

Penalties for late MTD submissions and payments are increasing from April 2025:

  • 3% of the tax due if 15-29 days late (up from 2%).
  • An additional 3% if 30+ days late (up from 2%).
  • A further 10% per annum penalty on amounts outstanding after 30 days.
  • HMRC interest rates on late payments also increase by 1.5% from 6th April 2025.

• Making Tax Digital (MTD) Expansion:

The timeline remains on track:

  • April 2026: MTD for Income Tax Self-Assessment (ITSA) applies to self-employed individuals and landlords with income over £50,000.
  • April 2027: Threshold drops to £30,000.
  • April 2028: Threshold drops again to £20,000.
  • Important Software Change: Taxpayers under MTD for ITSA must use MTD-compatible third-party software for quarterly updates and their final declaration (HMRC’s own filing service won’t be an option for the final step as previously planned).

How a Bookkeeper Helps:
Navigating MTD requirements and avoiding penalties is paramount. A bookkeeper ensures your records are digital, accurate, and submitted on time using compliant software. They manage interactions with HMRC, help you understand your obligations, and can advise on Tax Investigation Insurance to mitigate costs associated with potential enquiries.

3 – Business Rates Relief

• For businesses in the retail, hospitality, and leisure sectors in England, the current 75% business rates relief ended on 31st March 2025. For the 2025/26 tax year, this relief reduces to 40%, capped at £110,000 per business. This represents a significant increase in fixed costs for many high-street businesses.

• Longer-term plans involve introducing “permanently lower” rates for these sectors from 2026/27, funded by a higher rate (multiplier) on the most valuable properties, like large distribution warehouses.

How a Bookkeeper Helps:
Understanding changes to rates relief and budgeting for the increased cost is vital for cash flow management. Your bookkeeper ensures these costs are correctly accounted for and factored into financial forecasts.

4 – Capital Gains Tax (CGT) & Other Taxes

• CGT Rates:

The basic rate remains 18%, with higher/additional rates at 24%.

• Business Asset Disposal Relief (BADR):

The CGT rate for qualifying disposals under BADR increases from 10% to 14% from 6th April 2025 (rising again to 18% in 2026).

• Investors’ Relief:

The lifetime cap is significantly reduced from £10m to £1m.

• Furnished Holiday Lettings (FHLs):

The beneficial FHL tax regime is abolished from April 2025. Income will be taxed similarly to standard property rentals.

• Corporation Tax:

Remains at 25% for profits over £250,000, with marginal relief for profits between £50,000 and £250,000. Full Expensing and the £1m Annual Investment Allowance for qualifying plant and machinery investments continue.

• Inheritance Tax (IHT):

Reliefs are changing. From April 2026, a £1 million cap applies to Business Property Relief (BPR) and Agricultural Property Relief (APR), with relief dropping to 50% above this. Unused pension pots may fall into IHT scope from April 2027.

How a Bookkeeper Helps:
While strategic tax planning often involves an accountant, your bookkeeper provides the accurate, up-to-date financial data needed for effective planning around CGT, IHT, and Corporation Tax.
They ensure assets and reliefs are correctly recorded.

Key Dates for Your 2025 Diary:

Keeping track of deadlines is crucial to avoid penalties. Here are some key dates for businesses:
Ongoing: VAT returns and payments (deadlines vary based on your cycle, typically one month and 7 days after period end).
January 31, 2025: Balance of tax due for 2023/24 Self-Assessment; First Payment on Account for 2024/25 due.

April 6, 2025: Start of the 2025/26 tax year; Employer NI rate/threshold changes; Employment Allowance increase; CGT BADR rate increase; FHL regime ends; Increased late payment penalties/interest rates effective.

October 31, 2025: Deadline for paper Self-Assessment tax return (2024/25).
