Tax Ebookkeeping Context
This is a background context loader for Japan's Electronic Bookkeeping Act (電子帳簿保存法) that Claude automatically pulls when users ask about e-bookkeeping compliance in the shinkoku tax filing system. It's not meant to be invoked directly. Instead, it feeds Claude the three main categories of the law (electronic ledger storage, scanner storage, and mandatory electronic transaction data storage), explains the differences between standard and premium compliance levels, and clarifies how shinkoku meets both sets of requirements. The real value is in the practical guidance it provides for sole proprietors navigating the January 2024 mandate and the upcoming 2027 deduction changes. Think of it as a reference card that prevents Claude from giving generic or outdated tax compliance advice.
