Upstream Tax Analyzer

Tax depletion, depreciation, and amortization are important components of the tax compliance, provision, and planning processes for upstream oil and gas companies. Tax departments often spend significant time gathering data and preparing calculations rather than analyzing results.

The need for a new solution

Many companies still use spreadsheets to calculate tax cost recovery. Others are using outdated custom modules within their ERP system that now require manual manipulations outside the system.

Spreadsheets can require numerous manual processes that can result in issues with data quality, version control, and computational accuracy and more frequently now are creating control weaknesses.

As upstream companies continue to modify their portfolio of properties, these inefficiencies in maintaining tax basis records become more difficult and time-consuming.

What if you could:

  • Reduce the cycle time to maintain upstream tax basis recovery
  • Use a database to support tax basis of assets and
  • Spend more time on tax analysis and scenario planning?

Deloitte can help.
