Smart Tax Planning for Wearable Hardware Companies in 2026

In 2026, wearable technology companies across the UK will need to take a more strategic approach when investing in hardware. With rising costs, complex relief rules, and tighter margins, making the right tax choices around capital expenditure will be more important than ever. At Apex Accountants, we support wearable tech businesses through tailored tax planning for wearable hardware companies. We help firms structure investments in a way that supports growth, protects cash flow, and aligns with HMRC requirements. Our team works closely with startups and established businesses developing smartwatches, biometric devices, and sensor-based technology.

In this article, we explain how to handle capital expenditure on wearable hardware. You will learn the difference between depreciation and capital allowances for wearable technology, how to benefit from full expensing, and how to claim R&D tax relief when eligible. This guide will help you avoid common tax mistakes and make better use of available reliefs.

What Counts as Wearable Hardware CapEx?

Capital expenditure covers large, one-off purchases used in your business over time. For wearable tech firms, this could include:

• Smartwatches and fitness devices
• Medical-grade sensors and biometric tracking units
• Embedded hardware for research prototypes
• Testing equipment or data-collection units

Your business may qualify these assets as plant and machinery for capital allowances if you use them in your trade.

Accounting Depreciation vs. HMRC Tax Relief

While you depreciate hardware in your financial accounts (e.g., over 3–5 years), HMRC does not allow depreciation for tax. Instead, UK tax law provides capital allowances for wearable technology, offering real, deductible relief.

You must maintain two treatments:

• Accounts: Depreciate assets based on useful life
• Tax: Use capital allowances to reduce taxable profits

Confusing the two can lead to errors in corporation tax returns and lost reliefs.

Full Expensing: 100% Deduction in Year One

From April 2023, companies can deduct the entire cost of new, unused plant and machinery in the year of purchase under the full expensing regime.

Eligibility Checklist:

• The asset is new and unused
• Purchased by a UK company (not sole traders or LLPs)
• Used wholly for business
• Not used for leasing out to others
  

This regime is now permanent. If your wearable hardware qualifies, you can deduct 100% in year one—boosting cash flow and lowering tax bills.

Second-Hand or Leased Hardware: Other Options

If your hardware is second-hand or leased, it may not qualify for full expensing for wearable device companies. In that case, you can claim:

• 18% Writing Down Allowance (WDA) on main pool assets
• 6% WDA for integral features or long-life assets

We recommend planning purchases carefully before your financial year-end to make use of all available allowances.

R&D and Capital Expenditure: Dual Opportunities

Many wearable tech companies engage in R&D—developing new devices, sensors, or embedded tech. While hardware costs are capital in nature, you may still access tax relief through:

Research and Development Allowances (RDAs)

If hardware is used directly in R&D, you can claim 100% first-year capital allowances under the RDA scheme.

Examples include:

• Prototype wearables used solely in testing
• Custom testing rigs designed for development use

R&D Tax Relief for Revenue Costs

You can also claim R&D tax credits on:

• Staff salaries and NIC
• Software licences
• Subcontracted R&D
• Consumables like prototype materials

You cannot claim both RDA and standard R&D relief on the same expenditure. Proper cost classification is essential.

Key Tax Planning Tips from Apex Accountants

• Categorise spend: Separate R&D hardware from general business use hardware
• Check timing: Align purchases to claim reliefs in the same tax year
• Keep evidence: Maintain records showing use of hardware in trade or R&D
• Review R&D eligibility: Projects must involve technological uncertainty and skilled input
