Why Is AI Essential for Accounting Firms in 2026?

AI has become a critical part of modern accounting. Adoption among firms has jumped from around 9% in 2024 to over 40% in 2025, according to Wolters Kluwerโ€™s 2025 Future Ready Accountant Report.

This allows firms to shift focus from routine processing to strategic advisory, improving client satisfaction and business outcomes.
