Retention obligation: how long must you keep what?
Written by Ilias2 min read
As an entrepreneur you're obliged to keep your records for a certain time. The tax authorities can audit going back years. Many entrepreneurs don't know exactly what to keep for how long. This article explains the rules around the retention obligation.
How long is the retention obligation?
The standard retention period is seven years. This applies to your entire administration: invoices, receipts, contracts, your general ledger and your bank statements. The period starts after the end of the financial year to which the documents relate.
When does a longer period apply?
For data about real estate, such as a business premises, a longer retention period of ten years applies. This is connected to the VAT adjustment rules that apply to real estate. If you have property in your business, observe this longer period.
Can you keep records digitally?
You may keep your records digitally, and that's most convenient for most entrepreneurs. A scanned or digitally received invoice is allowed, provided it remains legible and can't be altered. Make a good back-up, so you don't lose anything.
Why is this important?
In an audit the tax authorities want to be able to inspect your records. If you can't produce documents, that can lead to an estimate of your income and an additional assessment. Well-organised, digital records that you keep tidily are your best protection.
