Hiring a personal tax consultant

Hiring a personal tax consultant can save you time, money, and stress—especially when navigating complex tax rules, self-assessment deadlines, or dealing with HMRC. But how much should you expect to pay for expert help?

What Is a Personal Tax Consultant?

A personal tax consultant provides tailored advice and tax services to individuals. Whether you're a self-employed professional, high earner, landlord, or have overseas income, a tax consultant helps you:

  • Optimise your tax liability
  • Prepare and submit self-assessment tax returns
  • Claim eligible reliefs or deductions
  • Respond to HMRC queries
  • Avoid fines and penalties

What Affects the Cost of Tax Consultancy?

1. Complexity of Your Tax Affairs

Simple self-assessments for sole traders or PAYE employees will cost significantly less than filing for individuals with:

  • Rental income
  • Capital gains
  • Foreign income
  • Trusts or inheritances

2. Filing History

Late or missing tax returns often require additional work. Avoid penalties—here's what happens if you don't file or pay on time

3. Level of Service

Some clients only need year-end filing, while others want proactive, year-round tax planning advice.

4. Credentials and Experience

Firms with chartered tax advisors, like Lawrence Grant, offer a higher level of service and compliance assurance than budget or DIY tax providers.

Is Hiring a Personal Tax Consultant Worth It?
