Recommended Tweaks to Filthy Rich

Ignore multiple taxation rolls in the same turn.  So if you roll 4 dice and get 3 "10"s, you only get one taxation.

Use a draft at the beginning.  Take one deed from every company and go around the table Settlers style, one clockwise, then counterclockwise starting from the last player, letting every player draft two companies.  Then shuffle the unclaimed deeds in with the rest of the deck and deal three more cards to everybody, and you're ready to begin.

Allow players to declare bankruptcy at any time.  The bankruptcy card we call the "Chapter 11" bankruptcy.  When played, you have companies, money, etc, reset to where it was at start, but draw new hand immediately, turn to any page, and may play that turn normally.

Instead of rolling a single die to determine "go to" page, roll two, and allow the next player his choice of page.

Don't allow Tic Toc to be hit twice before it boomerangs; it only gets income once, even if it is hit
twice.  This balances it quite a bit, as we find it to be too powerful a business.

With 2-3 players, before the game, remove the $6 and $8 Luxuries from the Luxury deck.  This usually prevents a lucky break from deciding the entire game in the first 3 rounds.
