Corporate accounting, accounting and taxation, the four major insurance policies, personnel and payroll
Description
Book Introduction
Company practice books from accounting to human resources

This is a manual that comprehensively covers accounting and taxes for small and medium-sized businesses, as well as corporate management tasks such as accounting, payroll, labor, finance, retirement pension, and the four major insurances.
It contains a tremendous amount of content in a huge volume.
I decided that I had to read this book 3 or 4 times.
If you look at books on labor law or wages, many of them are textbook-like.
It's difficult to find what you need in practical work in books, and I think this book really scratches the itch of those practitioners.
First of all, this book is quite long.
It is a truly substantial volume that would be useful if placed on one side of a practitioner's desk.
This book covers everything from wages and severance pay to personnel management, financial management, and even the four major insurance policies...
It is a book that covers all fields.
Corporate accounting, HR, and CEOs finally find answers to all their corporate questions.
Clear explanations, calculation formulas, and case studies provide easy solutions to the most pressing questions for practitioners! This work guide, perfectly tailored to your specific job, teaches you how to solve difficult numerical calculations with formulas.

Into the book
For the convenience of work, there is no problem for the company to scan the documents and store them on the computer, but to avoid tax issues later, you must manage the documents with the following in mind.
Of course, in practice, there are very few cases where scanning and storing on a computer poses a problem, but in the event of a dispute with the tax office in charge, the decision will be made according to law and principles, so it is recommended that you pay attention to the following matters in practice and handle your work accordingly.
1.
If you receive the qualification certificate on paper instead of online and then scan the paper, the scanned copy will not be accepted as the qualification certificate.
2.
If you receive proof online due to online payment, the information will be transferred to the National Tax Service from that site, so printing out the online proof will be recognized as valid proof.
3.
If you receive the original online and keep it, it is recognized as a valid document, but if you receive it on paper and then scan it, it is not recognized.
In other words, if you received the document online and saved it as a PDF file, it is recognized as qualified evidence, but if you received it on paper and then scanned it and saved it as a PDF, it is not recognized.

--- From "Financial Situation Report to the President"

· This refers to the time included in calculating the monthly salary.

· Refers to the working hours that serve as the basis for calculating the minimum wage.
· When calculating the salaries of mid-year hires and mid-year resignations based on paid working hours, there is an advantage in that the minimum wage issue does not arise.
· This is the working hours that serve as the basis for calculating regular hourly wages.
In the case of an 8-hour workday, 5-day workweek, paid working hours = (40 hours per week + 8 hours per week off) × 4.345 weeks = 209 hours
1.
5-day workweek with 4 hours of paid leave per day
· 1 week = [(8 hours × 5 days) + (8 hours + 4 hours)] = 52 hours
· January = [52 hours × (365 days ÷ December ÷ 7 days)] = 226 hours
2.
5-day workweek with 1 unpaid day off (Saturday) (normal)
· 1 week = [(8 hours × 5 days) + 8 hours] = 48 hours
· January = [48 hours × (365 days ÷ December ÷ 7 days)] = 209 hours
