Do you need an accountant to start a business in Europe?

Starting a business in Europe rarely requires an accountant on day one — but there is a real line between the point where doing your own books is sensible and the point where a professional quietly pays for themselves. This guide walks through where that line usually sits, what accountants actually cost, and which tasks good software can genuinely take off your plate. Obligations differ from one country to the next, so treat the figures below as a map, not a rulebook.

When you can safely do it yourself

If you are a sole trader or a small single-owner company with modest turnover, few invoices a month, no employees, and no VAT registration yet, DIY bookkeeping is entirely realistic. Cloud accounting software has closed most of the gap that used to justify hiring someone straight away. Tools like Xero start from around £15 per month for the entry-level plan (Xero, 2025), and comparable products across the EU sit broadly in the €10–€30 range for a starter tier — a fraction of a professional's fee.

At this stage your job is mostly discipline rather than expertise:

• Keep business and personal money in separate accounts (a dedicated account makes this painless — see our guide to business bank accounts for EU startups).
• Record every sale and expense as it happens, not in a year-end panic.
• Keep digital copies of invoices and receipts.
• Put money aside for tax you will owe later.

If your model is simple and your volumes are low, this is manageable for most of your first year. Before you commit, it is worth mapping how long your starting capital actually lasts under these costs — our startup runway calculator does that in a couple of minutes.

When an accountant starts to pay for itself

The calculus changes fast once any of the following enter the picture. These are the situations where a professional typically saves you more than they charge — in avoided penalties, reclaimed tax, and hours you get back.

You register for VAT

VAT is where DIY most often goes wrong. Registration thresholds, invoicing rules, reverse-charge mechanics and periodic returns all carry deadlines and penalties. From 1 January 2025 the EU's cross-border SME scheme lets a small business exempt its cross-border EU supplies if its EU-wide turnover stays under €100,000 and it stays under the national threshold (capped at €85,000) in each country where it sells; you register once in your home country, receive an "EX" identification number and file a single quarterly report (European Commission, SME VAT rules). It is a genuinely useful simplification — but understanding whether you qualify, and what happens when you cross a threshold mid-year, is exactly the kind of judgement call worth paying for.

You take on employees

Payroll is a hard deadline every single month: gross-to-net calculations, income tax withholding, social contributions, and country-specific filings. Get it wrong and both the tax authority and your staff notice immediately. Almost no first-time founder should run payroll manually.

You sell across borders

Selling into several EU countries multiplies the rules that apply to you — VAT treatment of goods versus digital services, One-Stop-Shop reporting, and differing local obligations. This is the clearest case for professional help, because the cost of a cross-border mistake dwarfs the fee.

You need to file annual accounts — or an audit

Under the EU Accounting Directive (2013/34/EU), companies file annual financial statements, with the depth of disclosure scaling by company size. Following the 2024 inflation adjustment (Commission Delegated Directive 2023/2775), the size bands — measured against two of three criteria over two consecutive years — are broadly:

• Micro: up to €450,000 balance sheet total, €900,000 net turnover, 10 employees.
• Small: up to €7.5m balance sheet total, €15m net turnover, 50 employees.
• Medium/large: above roughly €25m balance sheet total and €50m net turnover.

The practical headline: a statutory audit is generally required only for medium-sized and large companies (and public-interest entities), so most startups are exempt (Directive 2013/34/EU). But member states set the exact small-company thresholds and filing formats within the directive's limits, so what counts as "small" — and whether a light audit or review applies — varies by country. Preparing compliant statutory accounts, even without an audit, is usually where founders bring in a professional.

What it actually costs

Fees vary widely by country, complexity and scope, but as a rough guide for a small business:

• Ongoing bookkeeping commonly runs €80–€300 per month for a simple company, rising toward €400–€800 for higher transaction volumes or more complex cases (Integral, altertax, 2025).
• In the UK, small businesses typically pay £50–£150 a month as a sole trader and £100–£300 as a limited company (multiple UK accountancy sources, 2025).
• Year-end accounts and a corporate tax return, if bought separately, are usually a fixed annual fee on top.

City firms (Paris, for example) tend to charge 25–40% more than provincial ones, so location matters as much as scope.

What software can — and can't — replace

Modern accounting software genuinely handles a large share of the routine work:

• Issuing and tracking invoices
• Bank-feed reconciliation
• Expense capture and categorisation
• VAT return preparation (in supported countries)
• Basic management reports

What it does not replace is judgement: choosing the most efficient legal structure, deciding what is a deductible expense, planning for a VAT-threshold crossing, structuring cross-border sales, or defending your numbers if the tax office asks. A sensible middle path many founders take is a hybrid: run the day-to-day yourself in software, and pay an accountant a smaller fee to review the books periodically and handle the year-end filing. You keep costs down without carrying the compliance risk alone.

A simple way to decide

• Do it yourself if you are a sole trader or micro-company, not VAT-registered, no staff, low volumes, selling in one country.
• Get periodic help once you register for VAT, sell across borders, or your transaction volume climbs.
• Hire properly the moment you run payroll, approach an audit threshold, or spend more time on the books than on the business.

This all sits within the wider picture of how to start an online business in Europe, where your legal structure and country of establishment shape every accounting decision that follows.

This is general information, not legal or tax advice — rules vary by country and change; confirm with a qualified professional before acting.
