The verdict in three sentences
For a tax advisory boutique in Luxembourg targeting foreign investors and local SMEs, a budget of EUR 12,000 to EUR 24,000 covers a credible multilingual website delivered in 5 weeks. The corporate income tax simulator (about +EUR 3,500) and a regular tax insight blog are the two levers that turn the site into a qualified-meeting engine. A single new investor advisory mandate usually pays back the whole project.
What a tax boutique actually pays for in 2026
A tax firm does not sell a product, it sells trust. The site must prove expertise (insights, commentary on the annual budget law, sector references), reassure foreign investors (English and French versions, partner profiles, compliance) and make contact immediate (video meeting booking, WhatsApp or phone).
| Item | Essential package | Expert package | Comment |
|---|---|---|---|
| Custom design and build | EUR 6,000 | EUR 10,000 | Sober identity, partner and practice pages |
| Full second language | EUR 2,300 | EUR 3,700 | Essential for foreign investors |
| Video meeting booking | EUR 1,400 | EUR 2,300 | Calendar, email and messaging reminders |
| Tax insight blog (structure) | EUR 1,400 | EUR 2,800 | CIT, VAT, investment, transfer pricing categories |
| Local and technical SEO | EUR 900 | EUR 2,800 | Google profile, markup, mobile speed |
| Team training | included | EUR 2,400 | Self-service publishing |
| Total | EUR 12,000 | EUR 24,000 | 5-week timeline |
Recurring costs stay modest: EUR 60 per month for secure hosting with backups, plus optional maintenance at about EUR 400 per month if you want to outsource updates.
The tax simulator and insights: the two options that pay
A CFO or investor who runs a first estimate of their corporate income tax leaves contact details to get the full analysis. The simulator becomes a disguised qualification form. Tax insights feed search rankings on queries such as "Luxembourg budget law 2026" or "holding company taxation Luxembourg".
| Option | 2026 cost | Expected effect (order of magnitude) | Payback |
|---|---|---|---|
| CIT simulator (rates, minimum tax, credits) | +EUR 3,500 | 15 to 30 qualified leads per month after 6 months | 3 to 6 months |
| 2 insight articles per month | EUR 900 per month | +40% organic traffic in 12 months | 6 to 12 months |
| Budget law newsletter | EUR 700 (setup) | 300 to 800 decision-maker subscribers in a year | 6 months |
| Dedicated foreign investor page | EUR 1,800 | High-value leads, mandates of EUR 5,000 to 15,000 | 1 to 3 months |
| Secure client document space | EUR 5,500 | Fewer email exchanges, premium image | Immediate productivity |
The simulator must stay cautious: it shows an estimate, drives to a meeting and states that the calculation does not replace personalised advice. Parameters (rates, thresholds) are editable from the admin so the firm can follow each budget law.
Costly mistakes
Three pitfalls come up often. The first is a single-language site, while a large share of high-value requests comes from investors who expect English. The second is a blog launched then abandoned after three articles, which signals inactivity. The third is a slow mobile site: decision makers check firms on their phones between meetings, and every extra second of load time loses contacts.

Laura, partner at a four-person tax boutique in Luxembourg City, picks the Expert package with the simulator: EUR 24,000 + EUR 3,500 = EUR 27,500, plus EUR 900 per month of insights and EUR 60 of hosting, i.e. EUR 11,520 of recurring costs in year one. Total year-one cost: EUR 39,020. After eight months, the site generates an average of 18 requests per month, 2 of which become mandates averaging EUR 9,000. Over the last four months of the year that means 8 mandates, or EUR 72,000 in fees, about 1.8 times the investment.
FAQ
What is the minimum budget for a credible tax boutique website in Luxembourg?
Count on EUR 12,000 for a bilingual site with meeting booking and a blog structure. Below EUR 7,000 you usually get a generic template that does not reassure international clients.
How long does it take to go live?
The standard timeline is 5 weeks, including one week to write the practice pages with the partners. The CIT simulator adds roughly one week of testing on rates.
Does the tax simulator create liability for the firm?
It displays an indicative estimate with a clear disclaimer and invites a meeting for personalised analysis. The firm updates parameters after each budget law in under 10 minutes.
Do we really need two articles a month?
That is the pace that moves rankings within 6 to 12 months. At EUR 450 per article, the budget is EUR 900 per month, often covered by one small engagement per quarter.
Can the project be paid in instalments?
Yes, the usual schedule is 40% at order, 40% at acceptance and 20% at launch, by bank transfer or card.
