Don't you have to buy some Japan specific software like Freee for the e-Tax integration?

I like GnuCash, but for a business, it doesn't automatically handle sales/consumption tax, or employee payroll withholdings, you'd have to manually make splits in every transaction for that.

(Actually I think you all don't have to keep your consumption tax received in a separate account bc you net it out against purchases, but in the US we have to journal the tax into sales tax payable liabilities account, not revenue).

Can't speak of Japan, but where I've lived the percentage of tax is calculated against total sales, you don't need it separated beforehand

I believe there are some exceptions, with regulated or specially taxed goods like cigarettes, but there was none of those where I worked so it's mostly speculation
