azta vs IBFD: which tax research tool fits a European practice?
Quick verdict
For a European practice doing European work, azta is the better default. It covers the 24 jurisdictions that account for almost all of that work, cites each answer to the provision itself, and turns the research into a memo in Word. IBFD remains the stronger choice when the question genuinely leaves Europe, because its treaty and transfer-pricing depth spans far more jurisdictions than azta covers.
Choose azta if
- Your cross-border work is European: place of supply, reverse charge, permanent establishment, holding structures inside the EU and EEA
- You need tax and company law in one research thread rather than two subscriptions
- You want the answer to arrive as a draft memo in Word, not as a reading list
- A single professional needs access this week, at €27/month, without a procurement cycle
Competitor may fit if
- The work routinely reaches beyond Europe, where IBFD publishes country coverage azta does not
- Treaty analysis and transfer pricing are the daily job rather than an occasional question
- You want editorial commentary by named tax specialists that you can cite to a client as authority in its own right
Compare both if
- International tax functions that keep IBFD for global treaty work and give their European advisory team azta for day-to-day cited research and drafting

IBFD is the platform other tax research platforms get compared against. It has been the reference for international tax for decades, its country commentary is written by named specialists, and its treaty coverage is the reason large international tax functions keep it on the shelf. None of that is in dispute here, and a comparison that pretended otherwise would not be much use to you.
The question worth asking is narrower: what does a European practice actually research, and what does it cost to have the right tool for it.
The work most European advisers actually do
A Dutch adviser invoicing a German client, a Polish company incorporating in Romania, a Hungarian consultancy with an Austrian employee. These questions have two or three national sources and an EU directive sitting behind them, and they do not read the same way. They are also, for most European practices, the overwhelming majority of the cross-border work. azta was built around exactly that shape: ask once, get each jurisdiction cited separately, open the provision, check it yourself.
IBFD answers those questions too, and answers them well. It also answers questions about Brazil, Singapore and Nigeria, which is where a large part of its cost sits. If your practice never asks those, you are paying for reach you do not use.
Citation, and what counts as one
Both platforms are source-first, and both are a long way from a general chatbot that paraphrases a rule and sounds confident about it. They differ in what the source is. IBFD leads with editorial analysis: an expert reading of the rule, which is genuinely useful and which you can lean on. azta leads with the provision itself, in the language it was enacted in, with its in-force status shown, one click from the sentence that relies on it. For work you sign, the difference matters at the moment a client or a reviewer asks where a claim came from.
Where the research ends
IBFD ends at the answer. That is a reasonable place for a research platform to stop, and it is also the point at which the afternoon starts: you still have to write the memo. azta drafts it in Canvas, on your letterhead, with the citations carried through, and exports to Word. Research platforms and drafting are usually two purchases. Here they are one.
One publishes a price. The other quotes.
azta lists €27 a month, or €324 a year, and gives five cited questions a month free without a card. IBFD does not publish pricing at all: you ask, and someone comes back with a figure for your firm. We are not going to put a number on it here, because any number we used would be second-hand and probably wrong for you.
The difference in how the two are sold is the part that matters to a small practice. A quoted annual licence is a decision that needs a meeting, a budget line and usually a partner. A listed monthly price is a decision one adviser can make on a Tuesday afternoon. That is why a great many three-person practices in Kraków or Rotterdam have no tax research subscription at all and work from a mix of national sources and a search engine: not because they judged the platforms and declined, but because they never got as far as the quote.
Where IBFD may still fit
IBFD publishes coverage across far more jurisdictions than azta does, and if your questions regularly leave Europe, that reach is the whole argument. Its treaty database and transfer-pricing material are deeper than anything azta offers, its country commentary is written and maintained by named specialists, and in international tax its name carries weight in its own right. A practice whose daily work is treaty analysis or transfer pricing across continents should be looking at IBFD, and azta will not close that gap by covering Europe well.
Why azta is the better fit for a European practice
Because it matches what the practice actually researches. Twenty-four European jurisdictions in one workspace, tax and company law together, every claim cited to the provision in its enacting language with in-force status shown, the client’s own files read alongside the statute, and the memo drafted in Word at the end of it. At €27 a month it is a tool an individual adviser can adopt on a Tuesday, which is a different proposition from a quoted annual licence. For European work, that combination is not available anywhere else at any price.
Frequently asked questions
- Is azta a real alternative to IBFD?
- For European tax and company-law work, yes. azta covers 24 European jurisdictions with paragraph-level citation, reads client documents, and drafts the deliverable. For work outside Europe it is not an alternative, because azta does not publish coverage of those jurisdictions and does not claim to.
- Does azta cover tax treaties?
- azta covers treaty questions within its 24 European jurisdictions and cites the instrument behind the answer. It does not attempt IBFD’s global treaty database, which spans a far larger set of countries and remains the stronger tool for treaty work that leaves Europe.
- How does the price compare?
- azta publishes its price: €27 a month, €324 a year, with a free tier of five cited questions. IBFD does not publish pricing and quotes per firm, so we cannot make a like-for-like comparison and will not invent one. What we can say is that the two are bought differently: one is a listed subscription, the other a sales conversation.
- Can a firm use both?
- That is a common arrangement. International tax functions keep IBFD for global treaty and transfer-pricing work while their European advisory teams use azta for daily cited research and drafting. The two overlap on European tax and diverge everywhere else.
- How current is azta’s content?
- New legislation, directives and official guidance are indexed daily across all 24 jurisdictions, and every answer shows whether the provision it cites was in force at the time.
