Supplementing or amending tax returns

You can supplement or amend tax returns you have filed via the Internet provided that you have yet to be issued a final assessment. If you have yet to be issued a final assessment from the Tax and Customs Administration you can adjust the tax return you filed earlier and then file the adjusted tax return. The Tax and Customs Administration will then process the amended or supplemented tax return. Have you already been issued a final assessment? If so, the Tax and Customs Administration will not process the amended or supplemented tax return. You can then lodge a notice of objection.

Tax returns with financial statements for more than one financial year

You can enter financial statements for a maximum of 3 financial years in income tax returns you file via the Internet for yourself and 3 financial years in income tax returns for your partner. When you need to include financial statements for more than 3 financial years in your income tax return then you will need to use (commercial) software or make the necessary arrangements with a tax service provider.

You can enter financial statements for a maximum of 5 financial years in corporate income tax returns you file via the Internet. Consequently, you cannot file a tax return via the Internet for a tax entity comprised of more than 3 subsidiaries. When you need to include financial statements for more financial years in your corporate income tax return then you will need to use (commercial) software or make the necessary arrangements with a tax service provider.
