Understanding HMRC for Small Businesses
What is HMRC?
HMRC, or Her Majesty’s Revenue and Customs, is the UK government body responsible for collecting taxes, administering benefits, and regulating certain business operations. For small business owners, HMRC is integral to managing income tax, VAT, and corporate tax.
For small businesses, HMRC touches every financial aspect—ensuring compliance is non-negotiable. Understanding its functions, processes, and online tools can help reduce stress and simplify financial admin tasks, allowing you more time to focus on growing your business.
Key HMRC Regulations to Know
1. VAT (Value Added Tax)
VAT applies to most goods and services sold in the UK. If your business turnover exceeds £85,000 (current threshold as of 2024), you’re legally required to register for VAT. However, you may voluntarily register even if your turnover is below the threshold, which could be beneficial if most of your clients are VAT-registered businesses.
- Standard rate: 20% (most goods and services)
- Reduced rate: 5% (e.g., some energy-saving materials)
- Zero rate: 0% (e.g., most food and children’s clothing)
Businesses must submit VAT returns—typically quarterly—via HMRC’s Making Tax Digital (MTD) platform, which requires the use of compatible accounting software.
2. Income Tax
For sole traders and partnerships, profitability dictates income tax obligations. The self-assessment process ensures business owners pay taxes on profits above the £12,570 personal allowance (in the 2023/24 tax year).
Be sure to file your self-assessment tax return by the following dates:
- Paper submission deadline: October 31
- Online submission deadline: January 31
3. Corporation Tax
If you operate a limited company, you’ll need to pay corporation tax on your profits. The current corporation tax rate stands at 25% for profits over £250,000. For profits under £50,000, the rate is 19%, with a tapered rate for those in between.
Corporation tax returns (CT600) must be filed annually, and payments are due within nine months and one day of your company’s financial year-end.
Filing Deadlines and Penalties
Staying on top of tax filing deadlines is crucial. Missing these deadlines can result in penalties, which grow the longer you delay. Below are common penalties for late submissions and payments:
- VAT Returns:
- Late filing or payment triggers a point-based system. Reaching threshold points results in a fine.
- Income Tax Self-Assessment:
- Up to 3 months late = £100 fine
- Over 6 months late = £10/day penalty (up to 90 days)
- Over 12 months late = Additional penalties (based on the tax owed)
- Corporation Tax:
- 1-day late = £100 penalty
- Over 6 months late = 10% of unpaid tax due
Avoid penalties by keeping a reliable calendar of filing dates and using tools such as HMRC’s calendar reminders or tax consultancy services.
Record Keeping Best Practices
Proper record keeping is not just an HMRC requirement—it’s fundamental to good business management. HMRC requires financial records to be kept for at least 6 years, which may include:
- Receipts for purchases
- Sales invoices
- Bank statements
- Payroll records
- VAT returns
Tips for Simplified Record Keeping
- Move Digital
Use accounting software like Xero, QuickBooks, or Sage to keep detailed records. Many are MTD-compliant and save hours of manual input.
- Organize Your Paperwork
Group receipts and invoices by category, date, or department.
- Use Cloud Storage
Platforms like Dropbox and Google Drive allow access to records anywhere, ensuring secure backup for your files.
- Regular Updates
Dedicate time weekly or monthly to keep ledger entries up to date so it’s easier for tax season.
Resources and Support Available
HMRC offers several tools and resources to support small businesses in understanding regulatory requirements. Whether it’s navigating deadlines or grasping technical details, the following can offer guidance:
- HMRC Helpline Services

Common Mistakes to Avoid
Mistakes can lead to compliance issues or even financial penalties. Keep these common errors in mind and avoid falling into the same traps:
- Missing Filing Deadlines
Late submissions cost real money and damage credibility. Stay updated with HMRC reminders or hire an accountant.
- Neglecting VAT Registration
Failing to register for VAT once you exceed the £85,000 threshold can lead to steep fines.
- Poor Record Keeping
Misplacing invoices or forgetting receipts can result in time-consuming investigations by HMRC.
- Underestimating Tax Bills
Set aside enough money for upcoming tax payments. A useful rule of thumb is to reserve 25-30% of profits for taxes.
- Skipping Professional Help
Tax specialists and accountants can offer tailored advice, saving you significant time and reducing the risk of costly errors.
