Tax accounting services (including audit support)

Comprehensive tax accounting and audit services 

Deloitte can deliver a full range of tax accounting services, including audit support, offering a combination of process and tax accounting technical capabilities to drive the delivery of valuable insights, help mitigate risk and identify potential opportunities. Our professionals can assist companies in preparing tax provisions so they can confidently report results in mandatory financial statements. We can help clients understand the impact of new laws relating to income tax provisions, and how to account for uncertainty in income taxes under ASC 740. We work with you to ensure financial statements with income tax representations comply with IFRS standards.  

Our collaborative approach can provide the right scope and duration of expertise. Deloitte’s tax provision preparation assistance can involve outsourcing or co-sourcing, as well as providing specialists to support on specific foreign provisions, and using time-limited personnel contracting. Regardless of the arrangement, the objective of our tax provision support is the same: to develop relationships built on trust, expertise, and transparency that support your management of your organization and planning of transactions that help achieve your strategic goals.  

Deloitte specialists can also advise on complex tax accounting issues such as those related to Up-C structures, deferred tax validations, valuation allowance analysis, and uncertain tax positions. Additionally, we offer provision services including proforma financial reporting, remediation and restatements, and reconciliation of IFRS and US GAAP differences.  

We collaborate with you to achieve tax audit readiness and develop reliable audit response capabilities, including identifying and adopting technology solutions to augment individual expertise. Beyond assisting with internal activities, members of Deloitte’s broader audit teams can represent and support you in discussions with regulatory authorities.   

Deloitte’s tax provision and audit support teams build confidence in your tax compliance and audit positions by enhancing foundational and specialized capabilities and processes.
