Can I get full tax credit for electricity and full tax credit for household expenses, such as renovations, at the same time?

Yes. You can get a maximum electricity tax credit of €2,400 from a single electricity meter if you have paid €6,000 for your electricity. In addition to the tax credit for electricity, a tax credit for household expenses, such as renovations, is granted separately according to the usual maximum amounts of household expenses (€2,250 or €3,500). Electricity tax credit and other credits for household expenses have a common €100 credit threshold, which is primarily deducted from other credits for household expenses than the credit for electricity.
