EY US Business Tax Compliance services

The EY US Business Tax Compliance practice helps simplify and streamline compliance, deliver scalable solutions that grow with your business, and transform compliance into a source of strategic insight and value.

The tax landscape is evolving rapidly. Changing legislation and heightened reporting demands increase pressure on corporate tax departments to deliver speed, accuracy and insight, often with limited resources. Talent shortages add to these challenges, prompting many organizations to explore alternative operating models and technology solutions. 

We offer comprehensive business tax compliance services that cover the full spectrum of corporate income tax reporting. This includes federal, state and international filings required as part of the US federal return. As scrutiny and complexity grow, staying ahead of compliance requirements is now more critical than ever. Tax teams must balance shifting federal rules and complex financial reporting demands with precision and agility.

Smarter tax compliance through data, technology and insight

Our advanced technology, including the Global Tax Platform, streamlines data collection, analysis and reporting. AI-enabled tools enhance the quality and speed of tax return reviews by condensing hundreds of pages and forms into a clear, digestible format. These tools quickly identify potential risks and opportunities, turning data into insights faster. Intuitive dashboards provide transparency and confidence, helping you manage costs, control risks in real time, and unlock value through analytics and data visualization. This empowers your team to focus on higher-value priorities.
