  • FAQ for Outsourcing Services

    Financial report accounting

    Q1. Are you (i.e., EY) able to input data into EY (i.e., the client’s) ERP (NetSuite)?

    A1. Yes. We can input data directly into your company’s ERP accounting system. In many cases, it is more efficient to initially input data into our cloud application from the perspective of handling consumption tax. The standard outsourcing procedure is to input your company’s transactions in accordance with your company’s chart of accounts using a Japanese-English cloud application (“WebAccountingManager (WAM)”). If you would like to import accounting data to your headquarters’ ERP system, We have several EPR interfaces (e.g. NetSuite, Dynamics and SAP).

    Q2. How will monthly reports be prepared?

    A2. After closing the monthly ledgers, we will notify you once the latest reports (e.g. trial balance, the general ledger, income statements by segment) in WAM become available for viewing. We can also provide you with an English monthly BS (Balance Sheet) account prepared in a format of your choice or based on our standard template reconciliations.

The new hires will access the EPS via the links and enter their personal information. The HRA will then confirm the details, and afterward, the responsible EY personnel will receive a message. We will receive salary information from you via the Excel-based “Monthly Gross Pay Spreadsheet” template.

    Q2. How will overtime payments be calculated?

    A1. It is possible for us to open bank accounts for you at MUFG Bank, Ltd. under your Japanese corporation’s (or Japanese branch’s) name and make payment arrangements on your behalf. Furthermore, we can set up SWIFT MT940 services that will allow notification of transaction information daily through your foreign bank’s portal site.

    Q2. How should we send payment invoices to you? Should we send them directly to EY teams via post?

You will then be able to store the approved invoice on the portal site in PDF format. EY professionals will enter payment data in the online banking portal site and then ask you to grant payment approval. We are also capable of summarizing unprocessed invoices in English to obtain secondary approval from your parent company.


    Q1. If we wish to outsource to you the preparation of tax returns, will we also need to outsource accounting services to you?

    A1. Even if you do not outsource accounting services to us, the EY teams will prepare corporate income tax returns, local tax returns and consumption tax returns, provided that you manage your accounting ledgers in Japan and in accordance with Japanese tax laws and regulations. 

    Q2. Do you provide transfer pricing advice?

    A2. We will introduce you to the department within our group that specializes in transfer pricing.

    Q3. Are you able to prepare BEPS’ country-by-country reports? How about master files?

    A3. We assume that parent companies usually submit country-by-country reports (CbC reports). We can submit master files on behalf of your Japanese subsidiaries. It is the responsibility of shareholders to decide whether to preserve local files (documentation required to calculate arm’s length price) until the final tax return submission due date.

    Q4. Prior to filing the tax return, we need to have our US Tax Department review the tax return and grant their approval. Do you provide direct support for such a process?

    A4. Yes. We provide a service that includes preparing ledgers and tax return adjustment worksheets and directly contacting overseas tax departments.
    We will charge additional fees for this service.


    Q1. Do you provide advice and support for registering a company in Japan?

    A1. This is an area that must be handled by Japanese lawyers and judicial scriveners. We will introduce you to EY Law Co. who have a team that manages company secretarial matters, as well as Japanese law qualified lawyers.


We will examine journal entries that have been recorded in light of foreign accounting standards and group policies and propose adjusting entries for the purpose of preparing financial statements that will be attached to tax returns. Besides comprehensive accounting reviews, we also provide area-specific support such as reviewing employee expense reimbursements, AP module input and management.


We support preparing English semi-annual reports (financial statements and notes) prepared for IR purposes, and financial statements to be published in the prospectuses issued for overseas investors.


A. ERP support

Do you find the recording of journal entries into the accounting system and ERP system of your parent company burdensome? If that is the case, EY professionals can visit your office and carry out this task on your behalf or from an EY office by establishing a VPN connection. We will efficiently provide effective co-sourcing services by assigning the right staff for the right task. EY professionals have experience working with various systems, such as SAP, Oracle, Microsoft GP(Great Plains) or Microsoft NAV (formerly Navision). We also may contact your parent company as necessary to carry out operations.

B. Shared service center support

The number of companies relying on overseas shared service centers (SSC) to carry out their bookkeeping operations has increased, and relevant ledgers are usually created in English. There have even been cases where Japanese consumption taxes and withholding taxes have not been processed accurately. Furthermore, when accounting and tax treatments differ, an increasing number of companies must go through the additional burden of communicating with overseas SSCs to maintain consistencies between their ledgers and prepare tax return documents. The EY teams provide SSC service support by contacting SSCs, clients and contract accounting firms that prepare tax returns to prepare financial statements and account breakdowns required when filing tax returns, consumption tax statements and documents required for pro forma standard taxation. We can also prepare worksheets that are necessary for filing tax returns.

C. Consumption tax support

Due to the turbulent economic environment in recent years, branches and subsidiaries of foreign companies located in Japan are forced to cut down on costs.

As part of such efforts, there is a trend of relocating back-office functions (accounting, HR, payroll calculations, etc.) to SSCs in other countries or parent companies. As a result, the accounting systems used by SSCs or parent companies tend to produce errors of not recording Japanese consumption tax transactions properly. The issue becomes even more complicated because Japanese consumption tax is not always indicated on invoices, statements, receipts, and other evidential documents. For this reason, such issues tend to surface at the end of the fiscal year. Some companies cannot submit consumption tax reconciliation worksheets required by Japanese tax authorities to be prepared for the submission of consumption tax returns.


We try to be as transparent as possible in our professional fees and that fees is an important factor in determining which outsourcing vendor to retain. If there is interest in our services, we will hold an online session and walk you through each line in our Outsourcing Fee Calculator and share a printout with you, so you have a better idea of our costs.
