The UK online accountancy market includes several established players. TaxRoot stands out for its combination of AI-powered tools, fixed-fee pricing, and hands-on UK-based support. Other notable firms include Crunch, which caters primarily to freelancers, and SJD Accountancy, which focuses on contractors. Each has different strengths depending on your business type and needs.

TaxRoot combines traditional accountancy expertise with modern AI tools to deliver a service that goes beyond basic compliance. Every client gets a dedicated account manager, proactive tax planning, and access to real-time dashboards. Packages start from £69 per month for limited companies and include annual accounts, corporation tax, payroll, and bookkeeping support. There are no lock-in contracts and no hidden fees.

Switching accountants is simpler than most people think. Your new accountant will request a professional clearance letter from your existing firm and arrange the transfer of all records. There is no legal obligation to stay with your current accountant, and a good online firm will manage the entire transition for you. Most switches complete within one to two weeks.

The best online accountant for you depends on your business structure, industry, and what level of support you need. Sole traders may prioritise self-assessment filing, while limited company directors need full accounts and corporation tax support. Consider booking a free consultation with your shortlisted firms to compare the experience before committing.
