A Japanese renewable energy company was expanding its solar and wind power operations. The client wanted to make use of available tax incentives to reduce upfront costs and improve investment returns. Epic was brought in to help identify, apply for, and structure those benefits correctly.
The Challenge
The client planned several large-scale solar and wind projects, which involved major capital investment.
While they were aware that Japan offers tax incentives for energy-efficient equipment and green infrastructure, they weren’t sure how to apply or which systems qualified.
The company needed support understanding fixed asset classifications, applicable tax credits, and accelerated depreciation rules.
They also wanted to compare the financial impact of different options — for example, using special depreciation vs. direct tax credit.
Documentation requirements were also a concern, including what to submit to tax authorities and when.
Because the company worked with multiple vendors and contractors, it wasn’t always clear who should claim the benefits.
They also wanted to make sure they could continue to use these incentives in the future and avoid mistakes that could disqualify them.
Time was limited, as construction was already underway and deadlines for tax filings were approaching.
Their in-house accounting team had limited experience with tax incentive claims and didn’t have the capacity to handle the process on their own.
They needed a clear, practical roadmap with minimal disruption to day-to-day operations.
What did epic do
Epic reviewed the list of planned and purchased equipment and matched each item with relevant tax incentive categories.
We explained the difference between immediate expensing, special depreciation, and green investment tax credits.
Our team prepared simulation models comparing the tax savings and cash flow benefits under each approach.
We also supported preparation of the necessary documents for filing with the tax office, including fixed asset ledgers and application forms.
Epic worked with the client’s vendors to confirm eligibility requirements and avoid duplicate claims.
We helped the internal team understand which benefits could be carried forward or combined across fiscal years.
To prevent disqualification, we reviewed contract terms and payment timing to ensure they met legal conditions.
Epic remained available for follow-up questions and future filings, providing templates and training for internal use.

The Results
- Qualified assets identified and matched with correct tax incentive programs
- Optimized choice between depreciation and tax credit options
- Increased cash flow by reducing upfront tax burden
- Documentation prepared and submitted without delays
- No disqualification or rejection by tax authorities
