Support areas

Good business decisions require a sound understanding of tax and finance. We support company owners and management teams in identifying risks, capitalising on opportunities and choosing solutions that genuinely support the company’s growth.

Ongoing tax advisory and compliance services

We provide support with day-to-day tax and regulatory matters, such as tax returns (CIT, VAT, PIT, WHT) and compliance obligations (MDR, KSeF, DAC7, Pillar II, AML). We identify the risks and implications of planned actions.

Audits, controls and tax proceedings

We verify tax returns and carry out reviews of selected areas and analyses of specific transactions. We also provide support during tax controls and audits, tax proceedings and any dealings with the tax authorities.

Tax reliefs and business incentives

We help you take advantage of reliefs, such as R&D, IP Box, the Polish Investment Zone relief and the Estonian CIT. We assess the scope for applying preferential schemes, identify areas of support and assist with claiming reliefs.

Financial and tax due diligence

We prepare companies from an accounting and tax side for transactions and investment decisions. We analyse financial results and identify risks affecting the terms of the transaction.

Taxation in transactions and restructurings
