Tax Outsourcing Services

Growing multinational companies often lack the infrastructure and skilled resources necessary to manage ever-increasing tax complexities. To accomplish all the necessary operational tax work that your business requires, think of GTM as your back office for corporate tax services.

We have taken our decades of experience to build a Managed Tax Services (MTS) outsourcing model that delivers the best people, process, and technology to provide companies with an integrated, cost effective approach to outsourcing tax department functions.

Department Management

Tax Automation

Allow your team to keep their focus on strategic activities, and allow us to manage special projects such as data management, tax software implementations, and tax team collaboration tools.

Transitional and M&A

Corporate transactions create tax work beyond existing operations. GTM can help with transitional tax needs — due diligence and post transaction services –to ensure ongoing stability of all facets of the tax department on both sides of the transaction.

Resource Management

An efficient tax department has the right resources in the right place at the right time. We can help you determine and fill your resource needs for all tax functions – with staff loans or management of your entire tax department.

Internal Business Support

Business functions outside the tax department need to understand the tax implications of pending business transactions. We will work with your colleagues to help them make the right decisions.

Tax Compliance

The tax compliance process can be time consuming and disjointed. GTM’s proven 10-step tax compliance process will help accurately prepare and file returns on time.

Tax Provision

Tax provision requires execution of a considerable number of complex tax technical calculations in a short period. Our 10-step provision process brings the cadence you need to meet the high demands of financial reporting.

Audit Support

Companies often face challenges meeting their internal, external and federal compliance audit needs. We are equipped with the experience and know how to assist with IRS audits, local tax audits, and provide support throughout your SEC compliance and review.

Transfer Pricing

CbC Reporting, transfer pricing documentation and require advanced technical knowledge to execute. GTM has the right expertise to take this level of complexity off your plate.


Federal, international and state and local tax planning are important, whether the company is cash or ETR driven. We have tax planning expertise to help you maximize your tax position while mitigating risk.

Transaction Tax

The monthly SUT close cycle requires you summarize, compare and transform data from multiple sources quickly. GTM’s closed loop SUT compliance process starts with general ledger data assembly and ends with a link to general ledger accounts to minimize risk and maximize efficiency.

Some companies want to maintain ownership of tax functions, while others want an experienced tax firm to be entirely accountable and responsible for their tax needs. Some want a mix of both. Short-term or long-term, GTM assists with any or all discreet tax functions. If you are a company with little to no tax department, we can provide the infrastructure and resources to manage your entire tax operation.
