Q, please tell me what I should modify in tax.php file. My webshop is still "under maintenance" because it doesn't show prices with tax. I don't understand what it is to be modified. Before the upgrade from 1.5.1.1 it was all ok. Help!

You are not a developer, so there is nothing for you to do. This is for developers of custom order total mods, hence the "ATTN Developers". There is nothing to change in the tax.php file.
I am guessing your tax issue is because you don't have a value set for the 2 new settings in the options tab for Use Customer Tax Address and Use Store Tax Address.
There are 2 new settings in the setting page:

The "Store" tax address tells the store to assume the tax based off the store's location while the customer is not logged in.
Countries with VAT would set it to Shipping.
Sellers in USA would normally leave this disabled.
Can't think of any time you would set this to Payment. This is more of a On or Off feature.

The "Customer" tax address tells the store which address to base taxes off of. This would be for people who live in states or countries that require you to tax digital downloads. Since tax is normally based off of shipping address, but digital products don't need to be shipped, the tax was set to default to the payment address. But this may or may not be correct behavior, so this setting was added to give you the option. If you want to charge tax on digital downloads then set this to "Payment" address. Otherwise, set to "Shipping" Address. If you don't want to charge tax, set to "disabled"
