The Autumn Budget delivered by the Chancellor on November 26, 2025, confirmed that stability will come at a cost for UK businesses. For the e-commerce and retail sectors, which rely on tight margins, efficient supply chains, and large workforces, this Budget presents a complex mix of escalating employment costs, new compliance burdens, and welcome investment incentives.
At Unicorn Accountancy, we have distilled the key tax changes that will impact your commercial strategy and bottom line, effective from April 2026.
The Shockwave of Rising Employment Costs
The most significant immediate impact for e-commerce and retail businesses, sectors heavily reliant on labour for warehousing, fulfilment, and physical sales, is the dramatic increase in the cost of employing staff.

The Employer NICs Squeeze
The Chancellor confirmed a substantial tightening of Employer National Insurance Contributions (NICs):
Rate Hike: The main rate of Employer’s NICs (Secondary Class 1) is set to rise further to 15%.
Threshold Drop: Crucially, the Secondary Threshold (ST), the point at which employers begin paying NICs, will be sharply reduced from £9,100 to just £5,000 per annum.
The combination of a higher rate applied to a much lower earnings threshold means businesses must immediately re-forecast their payroll budgets for 2026/27. This move specifically targets businesses with high employee volumes, hitting the operational models of many large-scale e-commerce fulfilment centres and retail chains.
National Living Wage (NLW)
As widely expected, the National Living Wage (NLW) will rise to £12.71 per hour (for over 21s) from April 2026. While a boost for employees, this compounds the cost pressure on employers who will be paying the new, higher 15% NICs rate on a greater portion of these increased wages.
The SME Lifeline: Employment Allowance Boost
To mitigate the NICs impact on small and medium enterprises (SMEs), the Employment Allowance (EA) is being dramatically increased from £5,000 to £10,500. Furthermore, the restriction that excluded larger SMEs with an annual Employer NIC liability over £100,000 has reportedly been scrapped.
Unicorn Action Point: For qualifying e-commerce startups and small independent retailers, this allowance will be critical. You must ensure your payroll system is configured to claim the full £10,500 relief immediately from April 2026.
Supply Chain & Digital Retail Compliance
The Budget introduced specific measures that affect how online retailers source and sell goods internationally.
End of Low-Value Import Relief
The government announced the closure of customs arrangements that previously allowed some online retailers to import low-value goods duty-free. This move aims to ensure all businesses pay equivalent tariffs, but it introduces two key changes for e-commerce sellers:
Increased Import Costs: Retailers who source small, inexpensive items from overseas and relied on this relief will see their landed costs increase due to new duty liabilities.
Administrative Burden: The customs compliance process for international consignments will become more complex, requiring robust internal systems to track and declare duty accurately on every imported item.
Business Rates Relief for Physical Retail
In a targeted measure to support the High Street, the government confirmed permanent lower business rates for over 750,000 retail, hospitality, and leisure properties starting from April 2026. While digital-first businesses may not benefit directly, multi-channel retailers operating physical stores will see a welcome reduction in fixed overheads, making the high street a slightly more viable part of their strategy.
Business Owner Focus: Dividends Tax Hike
For the directors and owners of e-commerce SMEs who extract profits via dividends, the tax burden is increasing. The basic and higher rates of Dividends Tax will rise by 2% from April 2026, meaning higher marginal tax rates on personal income for many business owners.
Tax Incentives for E-commerce Investment
Recognising the need for businesses to invest in productivity and automation (a key driver for competitive e-commerce logistics), the Budget solidified several key capital allowance incentives:
Permanent 40% First Year Allowance (FYA): A new permanent 40% FYA has been introduced for main rate assets. This is a significant incentive for e-commerce firms looking to invest in new warehouse automation, robotics, specialised computing equipment, or significant IT system upgrades, allowing for accelerated tax relief on these capital expenditures.
Annual Investment Allowance (AIA) Maintained: The generous £1 million Annual Investment Allowance remains in place, offering immediate 100% tax relief on qualifying expenditure (such as plant and machinery) up to that threshold.
These allowances are crucial tools for Unicorn clients planning major investments in their digital and physical infrastructure to boost capacity and efficiency.
Unicorn Accountancy’s Post-Budget Strategy
The November 2025 Budget is a fiscal tightrope walk that demands immediate action from business leaders, particularly in the e-commerce and retail sectors.
Employment Cost Review: Immediately quantify the combined impact of the new 15% Employer NICs rate and the £12.71 NLW increase on your 2026/27 operating budget.
Customs Compliance Audit: Review your import practices. If you rely on sourcing low-value goods internationally, factor in the new duty costs and implement a robust system to manage customs declarations post-relief.
Maximise Investment Relief: If capital investment in automation or IT infrastructure is planned, speak to your Unicorn Accountancy adviser to structure expenditure to fully leverage the 40% FYA and the £1 million AIA before the new tax year.
Unicorn Accountancy is here to ensure your business remains compliant, optimised, and fiscally sound in this shifting tax landscape.
