New mod has been released that makes bills more realistic rather than fixing them on one value. It can be found here
In the official Sims 4 forum, and in MTS' forum, I've seen many people complaining about the enormous bills that come up weekly. Some have reported bills valued at over 20k simoleons. The reason for this is because of the game's new bracket taxing system.
This mod will eliminate all of that and modify bills.py to return only 100 as its value when get_bill_amount
is called. Translated into normal-speak, that means you get to pay only 100 simoleons! You'll live like a king in the Cayman Islands with all of your expatriated accounts and no taxes to pay!
Please understand that this mod could
have collision issues with other mods that make changes to bills. If you experience a crash, try unloading the one you don't want to use anymore and keep the more awesome mod, whichever one it may be.
Simply grab the zip
file provided and plop it into your mods (Documents\Electronic Arts\The Sims 4\Mods) folder. You do not need to extract it.
For this mod to work, you'll need to enable scripting mods from your options menu. Navigate to Game Options > Other > Script mods. This procedure will allow you to use any mods that are made with Python scripts as opposed to .package files.
Although he allowed me to use his injector module in my mod without giving him any credit, I will still thank scripthoge for injector.pyo.
