With overwhelming negotiation power based on legal grounds, we thoroughly protect business owners from tax audits. Over 100 consultations per year!

Are you feeling anxious about the sudden notification of a tax audit? Our office leverages extensive experience from over 1,000 cases of tax and accounting practices, with the lead tax accountant directly handling negotiations with the tax office. We do not approach the audit unprepared. We conduct at least two thorough simulations (rehearsals) in advance to alleviate any concerns before attending the actual audit. We never delegate tasks to unqualified staff; instead, we act as "the greatest ally of the business owner," using legal grounds to logically refute the tax office and minimize risks and additional burdens such as reassessments. Even if you have previously engaged in questionable practices, we will propose honest and optimal solutions.

The Takahiro Iwamoto Tax Accountant Office is based in Nishi Ward, Yokohama City, Kanagawa Prefecture, and is a tax accountant office that supports the growth of local businesses and individual entrepreneurs. Our greatest strength is that we do not delegate tasks to unqualified staff at all; we are committed to "complete direct support by the representative tax accountant." We empathize with the loneliness and anxiety that business owners face and provide consistent support with responsibility, from the initial consultation to daily chat consultations and final tax returns. Additionally, we are well-versed in the introduction and operation of cloud accounting software such as freee and Money Forward, and we also accommodate "full accounting outsourcing," where you only need to send us your receipts. By utilizing IT for speedy processing, we create an environment where business owners can focus on their core operations. Furthermore, we have an overwhelming strength in areas that require advanced expertise and negotiation skills, such as our "tax audit support" with over 1,000 cases handled and urgent "speedy filing for unfiled cases." As a trusted partner to accelerate your business, we flexibly accommodate meetings on weekends, evenings, and online.
