All invoices you send or receive are kept in your records. This is mandatory, because we must be able to check your administration. You save the invoices in the form in which you sent or received them. Digital invoices are therefore not printed, but stored digitally. You keep the invoices for 7 years. Invoices about real estate should be kept for 10 years.
You can also scan invoices and receipts and store them digitally. However, there must be a correct and complete representation of the original. It is important that the security features are also stored. You can read this in the brochure Your computerized administration and the tax retention obligation.
If you meet the conditions, you do not need to keep the original invoices and receipts. This digital administration must also be kept for 7 or 10 years and be verifiable within a reasonable period of time.
