Bookkeeping and retention for white return filers: books for 7 years, documents for 5 yearsEven with a "white return," you must keep records and hold on to them

People with real estate, business or forestry income must record income and expenses in books and keep books and documents even when filing a white return. Books recording income and expenses must be kept for 7 years, and documents such as invoices and receipts for 5 years. Failure to keep books or insufficient entries may lead to heavier additional taxes.

Retention period (years)
Statutory books (income and expenses)7years
Optional books5years
Settlement documents such as inventory lists5years
Invoices, delivery notes and receipts5years

Key points

  • Bookkeeping: record the date, counterparty, amount etc. of transactions in an orderly way. A simple method of writing only the daily totals together is also allowed
  • Retention period: books recording income and necessary expenses (statutory books) are kept for 7 years
  • Optional books, documents related to settlement such as inventory lists, and documents such as invoices, delivery notes and receipts are kept for 5 years
  • People with miscellaneous income from business whose income two years earlier exceeded JPY 3 million must keep documents related to cash and deposit transactions
  • From amended returns etc. for tax returns for 2023 (Reiwa 5), the additional tax on omitted income caused by failure to keep sales-related books or insufficient entries is increased by 5% or 10%
Who is affected: White return sole proprietors and real estate owners, and people with miscellaneous income from business over JPY 3 million

What to do in practice

  • Record sales in your books without gaps, even if only as daily totals, and keep them for 7 years
  • Keep invoices and receipts for 5 years. Also check the conditions under which electronic records can replace them
Note: To replace paper with electronic records, certain requirements must be met. For details, please check the NTA's guidance.

People who run a shop or rent out rooms must write down their money coming in and going out in a book, even with a "white return," which needs no special application. The books you write and the receipts you get must be kept, not thrown away, for a set number of years.

What you do even with a white return
  • Applies: Write money in and out in a book
  • Applies: Keep books for 7 years
  • Applies: Keep receipts and invoices for 5 years
  • Does not apply: No need to keep records

Points

  • Write earnings and payments in a book, even if only as daily totals
  • Keep books for 7 years, and receipts and invoices for 5 years
  • If your sales records are missing, extra tax can become heavier
For example: It's like keeping a homework notebook where you write every day how much came in and how much you spent.
