How to Do Small Business Accounting in 2025 (UK Gun Shops and Firearms Dealers)

Are you running a gun shop or firearms dealership in the UK? Then you already know the industry is tightly regulated — and your finances should be no different.

Smart, compliant accounting is about more than staying out of trouble with HMRC. It helps you manage VAT, maximise profits, and reduce your tax bill legally. Here’s your ultimate guide to small business accounting for UK gun businesses in 2025.

Why Accounting Matters in the Firearms Industry

From managing your inventory and expenses to calculating VAT and Corporation Tax, accurate accounting gives you the financial control you need. It also supports:
  • Home Office compliance
  • Efficient business scaling
  • Lowering your tax liabilities
  • Clear cash flow planning

What Is Small Business Accounting?

In simple terms, it’s tracking the flow of money through your business. This includes sales, expenses, VAT, payroll, taxes, and stock.

Solid accounting is the foundation for:

  • Accurate profit & loss tracking
  • HMRC compliance (VAT, PAYE, MTD)
  • Strategic decisions on hiring, stocking, and expansion

7 Steps to Smarter Accounting in 2025

1. Separate Your Finances from Day One

  • Open a dedicated business bank account
  • Register your business structure (Ltd, sole trader, etc.)
  • Apply for a business credit card to build a credit profile
  • Link your accounts to modern accounting software (Xero, QuickBooks, FreeAgent)

💡 This keeps your finances clean, makes tax returns easier, and unlocks future funding options.

2. Use Accounting Software That Works for You

Pick MTD-ready tools that integrate with your bank and streamline admin:

3. Track Expenses & Know What to Claim

You can deduct legitimate business expenses before paying tax:

  • Marketing (Online advertising, events, social ads)
  • Business insurance
  • Premises costs (rent, rates, alarms, signage)
  • Tools, security systems, vehicle prep
  • Travel, fuel, staff training
  • Trade shows and dealership events

💡 Capital allowances can be claimed on vans, refits, tools, and large assets.

4. Register for VAT & Stay Compliant

If turnover exceeds £85,000, you must register for VAT.

  • Standard Scheme: Reclaim VAT on purchases
  • Flat Rate Scheme: Simpler but fewer reclaims (check if it’s right for you)
  • Consider the Margin Scheme for second-hand vehicle stock

✅ Submit VAT returns via Making Tax Digital (MTD) every quarter.

5. Pay Yourself Properly & Manage Payroll

If you’re paying staff or yourself as a director:

  • Register for PAYE
  • File monthly RTI reports
  • Understand 2025 NI increases: Employer rate is now 15%

💼 Directors: Use a tax-efficient mix of salary + dividends + expense claims with your accountant’s help.

  • Review gross margins and stock turnover quarterly
  • Reassess pricing, inventory levels, and staffing
  • Use reports to guide key decisions
  • Schedule regular check-ins with your accountant

💡 If you’re spending too much time on admin, it’s probably time to outsource.
