The CTA (Chartered Tax Adviser) qualification is awarded by the Chartered Institute of Taxation (CIOT) and is widely regarded as the gold-standard tax qualification in the UK. It comprises Awareness, Advisory and Application papers plus a professional responsibilities exam, and three years of relevant tax work experience. CTA is the natural step beyond ATT for tax professionals targeting senior advisory or specialist roles.
What is the CTA?
CTA stands for Chartered Tax Adviser, the senior professional qualification of the Chartered Institute of Taxation. CTA holders use the letters CTA after their name and become full members of CIOT. The qualification is recognised by HMRC, professional bodies, and employers as the leading UK qualification in tax advisory work. It complements (and is often taken alongside) chartered accountancy qualifications such as ACA and ACCA.
Structure of the CTA
To qualify as CTA you must complete:
| Component | What it tests | Format |
|---|---|---|
| Awareness paper | Broad knowledge across multiple tax heads (e.g. corporate, personal, indirect) | 3-hour written exam, three modules from a choice |
| Advisory paper(s) | Detailed tax planning and advice in chosen specialisms | 3.25-hour written exam(s) |
| Application and Professional Skills paper | Tax case study testing application of multiple tax heads | 3.25-hour written exam |
| Professional Responsibilities and Ethics | Ethical conduct, PCRT, tax morality | Computer-based assessment |
| Law and accountancy computer-based exams | Foundations of law and accountancy | Computer-based, often exempted for ACA/ACCA |
| Practical experience | Three years of relevant work in tax | Self-certified, supported by supervisor |
Candidates choose Advisory papers from specialisms including: Taxation of Owner-Managed Businesses, Domestic Indirect Taxation, Cross-Border Indirect Taxation, Inheritance Tax, Trusts and Estates, Taxation of Major Corporates, Taxation of Individuals, and Human Capital Taxes (and other specialist papers from time to time).
Entry routes
You can sit CTA exams via several routes:
- ATT-CTA route: the standard path: complete ATT first, then progress to CTA
- Joint Programme with ACA or CA: ICAEW or ICAS students can sit some CTA papers in parallel for combined chartered tax and chartered accountant status
- ACA CTA Joint Programme: structured route co-designed with ICAEW
- Direct entry: graduates and qualified accountants can register directly with CIOT and sit the exams
How long does CTA take?
Most candidates complete CTA exams in 18 months to three years, depending on study capacity and how many papers are sat per sitting. Combined with the three-year practical experience requirement, total time to membership is typically three to five years from starting CTA study, often built on top of an earlier ATT or ACA qualification.
Cost
CIOT charges:
- Student registration fee on joining

Total cost over the qualification, self-funded, is commonly £4,000 to £10,000 including tuition. Most candidates are employer-funded, particularly in tax-specialist firms and Big Four tax practices.
Career outcomes
CTA holders typically work in:
- Tax practice: tax senior, tax manager, tax director, tax partner
- Big Four and mid-tier tax departments: personal tax, corporate tax, VAT, transfer pricing, international tax, expatriate tax, R&D tax credits
- In-house corporate tax: head of tax, tax manager in FTSE-listed groups
- HMRC: senior compliance, policy and technical roles
- Boutique tax advisory firms: often combined with other qualifications such as ACA
CTA-qualified tax advisers in mid-tier firms typically earn from around £45,000 newly qualified to £100,000+ at director or partner level, with higher pay common in Big Four and London markets.
ATT (Association of Taxation Technicians) is the technician-level tax qualification: appropriate for tax compliance roles and as an entry into the profession. CTA is the chartered, advisory-level qualification. Most career tax professionals do ATT first, then progress to CTA.

Frequently asked questions
Is CTA harder than ACA?
CTA is highly specialised and the Advisory papers are technically demanding, but it covers narrower ground than ACA. Many practitioners hold both.
Do you need to be an accountant before doing CTA?
No. You can register directly with CIOT. However, candidates from non-accounting backgrounds may need to sit the law and accountancy computer-based exams that ACA/ACCA holders are typically exempted from.
What is the difference between ATT and CTA?
ATT is technician-level and focuses on tax compliance. CTA is chartered, advisory-level, and focuses on planning, complex computations and giving tax advice.
Can you take CTA without three years of experience?
You can sit the exams without three years of experience. Membership and use of the CTA designation requires the practical experience to be signed off.
