ALTO Advisory – Tax, Accounting, ESG and HR Advisory

ALTO Advisory is one of the fastest-growing advisory firms in Poland, established in 2011 and headquartered in Warsaw. The firm was founded by Kamil Lewandowski and Paweł Fałkowski, who from the outset built it around a combination of deep expertise, a modern approach to advisory, and a genuine understanding of business needs. ALTO specialises in tax advisory, accounting, payroll and HR, ESG, and insurance brokerage — providing businesses with comprehensive support across the areas critical to their security and growth.

The ALTO team today comprises nearly 170 professionals. With close to 15 years of experience, thousands of completed projects, and international affiliations enabling collaboration with experts across more than 100 countries, the firm is well positioned to serve clients operating in complex, cross-border environments. ALTO Advisory works with companies across real estate, life sciences, technology, financial services, energy, logistics, and VC/PE — delivering solutions that strengthen tax security, streamline processes, and support business development.

The firm is regularly recognised in prestigious rankings, including international ones such as ITR World Tax and ITR World TP, confirming its standing as one of the leading advisory firms in Poland.

Our Services — Comprehensive Advisory with a Focus on JPK CIT and Technology

ALTO Advisory offers a broad portfolio of advisory services spanning tax, accounting, payroll and HR, ESG, and insurance brokerage. Central to the firm’s current focus, however, is helping businesses navigate the new JPK CIT reporting obligations — an area where ALTO has developed its most advanced capabilities, combining subject-matter expertise with purpose-built technology.

At the heart of this offering is ALTOOL JPK CIT, a proprietary application developed by ALTO Advisory’s experts that automates the preparation, validation, and submission of JPK CIT files. The tool enables companies to manage their tax data securely and efficiently — eliminating errors, reducing the workload on finance teams, and ensuring full compliance with the requirements of the Polish Ministry of Finance. ALTOOL JPK CIT features automated data mapping, advanced control rules, XML structure validation, error reporting, and secure file submission, all within an intuitive, user-friendly environment.

Alongside the technology, ALTO provides full substantive support for JPK CIT compliance: readiness audits, process analysis, tax advisory, representation before tax authorities, and ongoing consultation.

The firm’s broader service offering includes:

• Tax advisory — domestic and international tax, transfer pricing, tax audits, incentives, and restructuring
• Accounting outsourcing and tax compliance
• Payroll and HR services
• ESG advisory and reporting
• Insurance brokerage and corporate insurance
• ALTOstratus — proprietary technology tools supporting reporting and process automation

By combining advisory expertise, technology, and hands-on experience, ALTO Advisory helps businesses operate more securely, more efficiently, and in step with an ever-evolving regulatory landscape.
