VAT reduction during house construction

Today I was in a price negotiation conversation with the seller of the [Fertiggarage]. He has been talking about the 3% reduction the whole time. I believe that slowly all sellers (house, garage, ...) try to increase their price or give at least little discount to the builder.

Of course it will be like that. Or does anyone really believe that in retail a product will cost only €1.94 instead of €1.99 in July?

Only those who already have a fixed contract can benefit. New offers now will be adjusted. And it's really unfortunate for those who sign the construction contract now, because hardly any general contractor will inform that the higher tax rate will be charged with the final invoice. That quickly becomes a five-digit amount.

Of course it will be like that. Or does anyone really believe that a product in retail will cost only €1.94 in July instead of €1.99?

At least the food retail sector has announced this, as there is a price war. When one goes down, the next follows ... wait and see.
Much more interesting is the question of how strong the price increase will be when the promotion ends in 2012. Then the current €1.99 will temporarily become €1.95 and on 1/1/21 then €2.19.
The consumer will have forgotten the original price and will be mentally prepared for an increase due to the tax.

The whole thing stinks.
That is supposed to cost 20 billion EUR.
Then rather 250 EUR helicopter money for everyone.

I probably have bad luck. My contract says: Fixed price xxx including VAT We do have installment payments with shown VAT, but I think that will definitely be adjusted by the general contractor

Take a look at the T&Cs. Mine says fixed price and then microscopically small "except §xy". It then states that the price changes with the VAT.

So, we are also building with a property developer, planned acceptance in 9/2020.

In our KV, there is a fairly clear explanation on the topic of USt., surely meaning VAT here, right?
"The fixed price was calculated based on a VAT rate of 19%. Should the VAT rate change before the due date of the last purchase price installment, the purchase price installments will change by the increase of the VAT that becomes due after the date specified as the reference date in the amendment law."

Nice that they assume an "increase" here. However, the section begins with "change," so it should also apply to the unlikely case of tax reductions...

Let's hope the next installment is not due until July.
