Requesting an OV-verklaring
If you pay your own travel costs for your journey to work, you can request a travel deduction from the Tax Authority. To do so, you will need an OV-verklaring or a travel declaration (proof that you've travelled on public transport). Since NS reports season ticket data directly to the Tax Authority, you do not need to request an OV-verklaring from NS.
What is an OV-verklaring?
In order to deduct public transport expenses, you need a public transport statement or 'OV-verklaring'. This statement is proof that you have travelled on public transport.
When do you need to request an OV-verklaring?
How and where you can request an OV-verklaring depends on which ticket you use:
Annual season tickets
If you travel with an annual season ticket, then NS provides the season ticket details directly to the Tax Authority, so you do not need to request an OV-verklaring, except when you need one for the period before 2016.
In addition to the information that NS provides to the Tax Authority, you can also prove that you have travelled with public transport via Mijn NS. Here you can create an overview of your travel history, which you can then provide to the Tax Authority.
For other NS subscriptions, it depends on your employer. If the NS-Business Card is paid for by your employer, then you do not need an OV-verklaring. Freelancers can request tax refunds using invoices from Mijn NS Zakelijk .
Student travel product
Travellers with a Weekly- or Weekend season ticket can request an OV-verklaring from DUO (Dienst Uitvoering Onderwijs).
No season ticket
If you travel without a season ticket, then you can request a public transport travel statement from your employer. This statement and your tickets are proof to the Tax Authority that you have travelled on public transport. At the OV-chipkaart website, you can create an overview of your travel history using your OV-chipkaart.
The information above only applies to travelling with NS, however. If you have travelled with other rail carriers, you may need to request a statement from the other carriers.
Multiple work locations
If you travel to multiple locations for work on the same day, then you can only deduct the travel costs for the destination you travel to most often. In the event that you travel to an equal number of destinations, use the one for which you travel the longest distance. For an overview of the amounts you may deduct, see the Tax office public transport deduction table.
