ACCA basics
ACCA vs CTA: which route into tax is right for you?
ACCA is a broad accountancy qualification; the CTA is the UK's specialist qualification for tax experts. They are not really rivals, and many people do both. Here is how they compare and how they fit together.
Updated September 2026 · 7 min read
ACCA (the Association of Chartered Certified Accountants) and the CTA (Chartered Tax Adviser, awarded by the Chartered Institute of Taxation) are both highly respected, but they answer different questions. ACCA asks "do you want to be a rounded accountant?". The CTA asks "do you want to be a tax specialist?".
This guide compares them fairly on breadth, specialism, exams and career, and explains why the two are so often taken together.
The short answer
ACCA is a broad qualification covering the whole of accountancy: financial reporting, audit, management accounting, financial management, and tax among them. The CTA is a deep, specialist qualification focused entirely on UK tax, and it is regarded as the leading tax qualification in the UK. If you want a broad finance career with options across practice and industry, ACCA is the natural choice. If you are set on becoming a tax specialist, the CTA is the badge to aim for, usually after building a foundation first.
Crucially, they are complementary rather than competing. Plenty of tax professionals qualify with ACCA (or the ATT, the Association of Taxation Technicians) for breadth and grounding, then take the CTA to specialise.
What each qualification is
ACCA makes you a Chartered Certified Accountant. It is broad and flexible, open access, and internationally recognised. Tax is part of it, through the Taxation (TX) and Advanced Taxation (ATX) papers, but ACCA covers far more than tax. Our plain-English guide to ACCA explains the whole qualification.
The CTA is the Chartered Institute of Taxation's advanced qualification for tax advisers. It goes much deeper into UK tax than any general accountancy qualification, testing advanced technical knowledge and application across areas such as personal, corporate and business taxes, along with professional responsibilities, ethics and law. It usually assumes some prior grounding, which is why many candidates take the ATT or qualify as an accountant first.
How they compare
The headline difference is breadth versus depth. ACCA gives you the full toolkit of an accountant; the CTA turns you into a genuine tax expert.
Careers and recognition
ACCA opens doors across practice and industry, from financial reporting and audit to management accounting and finance leadership, in the UK and internationally. The CTA is prized specifically in tax: in the tax teams of accountancy and law firms, in specialist tax advisory, and in senior in-house tax roles. Holding both is a powerful combination, giving you the credibility of a qualified accountant and the depth of a tax specialist.
A simple way to frame it: ACCA makes you an accountant who understands tax; the CTA makes you a tax specialist. Many people become the first, then the second.
Which should you choose?
Choose ACCA if you want a broad, flexible, internationally recognised accountancy qualification, and you want to keep your options open across finance. Choose the CTA if you are certain you want to specialise in tax, ideally after a foundation such as the ATT or an accountancy qualification. For many people the best answer is "ACCA first, then decide", because ACCA keeps every door open, including the tax one. If you are comparing other routes, see our ACCA vs ACA and ACCA vs AAT guides.

Frequently asked questions
Can you do both ACCA and the CTA?
Yes, and it is a common and complementary combination. Many tax professionals qualify with ACCA for breadth, then take the CTA to specialise. Together they signal both all-round accountancy competence and genuine tax expertise, which is highly valued in tax roles.
Do you need ACCA before the CTA?
Not specifically, but the CTA assumes some grounding, so most candidates come to it after the ATT, an accountancy qualification such as ACCA or ACA, or relevant tax experience. Starting with ACCA gives you a strong foundation and keeps your options open if you later decide tax is not your specialism.
Is the CTA harder than ACCA?
They are hard in different ways. The CTA is narrow but extremely deep in UK tax, which makes it very demanding within its field. ACCA is broader and spreads its difficulty across many subjects. Neither is simply harder; it depends on whether you prefer depth in one area or breadth across finance.
Does ACCA cover enough tax on its own?
ACCA covers tax well through its Taxation and Advanced Taxation papers, which is plenty for a general accountant. If your role is mainly tax advisory, though, the CTA goes considerably deeper, which is why specialists tend to add it rather than rely on ACCA's tax papers alone.
Is the CTA only for accountants?
No. The CTA is taken by tax advisers from a range of backgrounds, including lawyers and career tax professionals, not only accountants. What they share is a focus on tax as a specialism, whether they came to it through accountancy, law or direct tax work.
