Best Accounting Firms in Poland for Foreign Companies (2026): 7 Firms Reviewed

Every foreign client who opens a company in Poland asks me the same question sooner or later: who should do our books? Polish accounting is detailed, strictly regulated and changes often, so the choice matters more than in most countries. This ranking is written for a company from the US, the UK or the DACH region that needs accounting firms in Poland it can work with in English – for bookkeeping, payroll, VAT and the annual financial statements. I kept 7 firms that explicitly serve foreign-owned companies.

How I ranked the accounting firms in Poland

I ranked the accounting firms in Poland by quality first, fit for a foreign company second and price third:

Focus on foreign-owned companies – English-language service, reporting for a foreign parent and experience with company setup.
Scope of services – bookkeeping, payroll, VAT, financial statements and help with the authorities from one firm.
Credentials – licensed tax advisors and auditors, international networks and certifications.
Pricing transparency – published rates or minimum fees where available.

I left out tax-only advisers and online accounting platforms that work only in Polish. Team sizes and client lists below are the firms’ own published figures.

The 7 best accounting firms in Poland, reviewed

Every accounting firm in Poland below gets the same treatment: who they are, what clients say, the facts that matter when you hire, and my opinion on who should – and should not – work with them.

1. getsix

Accounting, payroll and company setup for foreign investors, in English and German

getsix has been serving foreign investors in Poland since 2007. From its headquarters in Wrocław and offices in Warsaw, Poznań, Szczecin, Katowice and Rzeszów, plus a representative office in Berlin, a team of about 220 handles accounting, payroll, VAT registration and refunds, transfer pricing, company registration and virtual offices for more than 400 clients. It is a member of HLB International and certified to ISO 9001 and ISO 27001.

What clients say. Clutch: 4.9/5 from 6 reviews. Google: 4.7/5 from 13 reviews.

Facts: in Poland since 2007 · Wrocław and 5 other cities · about 220 people · English, German and Polish.

My take: the most complete package for a foreign company entering Poland – setup, books, payroll and compliance under one roof, with German speakers for DACH clients. Best for: German and international companies with a Polish subsidiary. Not for: a one-person business on a minimal budget.

2. CGO Finance

Bookkeeping and payroll only for foreign-owned companies

CGO Finance in Warsaw, part of the CGO Group, works exclusively for foreign-owned Polish companies and branches of foreign companies, in English. A team of about 40 serves more than 200 clients with bookkeeping, payroll, VAT, CIT and controlling; company registration is handled by its sister firm CGO Legal.

What clients say. Clutch: 5.0/5 from 9 reviews. Google: 4.4/5 from 14 reviews.

Facts: Warsaw · about 40 people · $50–99/h · minimum project $1,000 · English and Polish.

My take: the purest specialist on this list – every client is foreign, so English reporting and foreign parent requirements are the default, not an extra. Best for: small and mid-size foreign-owned companies. Not for: companies that also need audit or legal work from the same firm.

3. Dudkowiak & Putyra

My take: ideal when your accounting is tied to legal questions – setup, contracts, employment of foreigners – and you want one firm for both. Best for: foreign investors setting up in Poland. Not for: simple bookkeeping on a tight budget.

Facts: Warsaw headquarters · about 400 people · 18 countries · English, German, Polish and Romanian.

Quality, specialisation and what accounting firms in Poland charge

Accounting firms in Poland usually charge a monthly fee based on the number of documents, employees and entities rather than an hourly rate. Specialists such as CGO Finance and Adam Jeżak list rates of $50–99 per hour on Clutch, while regional groups such as Accace sit at $100–149. Quality and fit come before price: a cheap firm that cannot report in English or prepare documents for your parent company will cost you more later.

The main choice is between boutiques, where a tax advisor knows your company personally, and larger firms that cover several countries and offer audit-grade processes.

How to choose an accounting firm in Poland

Choosing an accounting firm in Poland as a foreign company starts with three questions: does the firm work in English every day, can it report in the format your parent company needs, and who signs off your tax returns? Ask for a sample monthly report and for the name of your dedicated accountant.

Also check that the accounting firm in Poland carries professional liability insurance – it is mandatory for bookkeeping services in Poland – and that it is ready for KSeF, the national e-invoicing system.

Accounting firms in Poland: FAQ

The best accounting firm in Poland for a small foreign company is, in my opinion, CGO Finance, which works only for foreign-owned companies. Adam Jeżak’s firm is a strong alternative for US and Swiss clients.

My verdict: which accounting firm in Poland to hire

Choosing among accounting firms in Poland depends on your size and setup. For a complete entry package in English or German, hire getsix. For a small foreign-owned company, hire CGO Finance.
