If you placed and paid an order on our website before the normal filing deadline expired (so before May 1, of the year following to the concerning tax year), we request extension for filing of your return with the Dutch Tax Authorities. Filing for extension is a standard procedure and does not have downsides. When extension for filing is granted, the filing deadline will be extended: + 1 year (so the return needs to be filed within 1 year after the normal filing deadline expired). Note that the Dutch tax authorities charge interest on payable amounts, so filing late could lead to interest charges on top of any payable amount in income tax. If you expect a payable amount, please let us know so that we can prioritize.
