Up your W-4 deductions, if W-4s will do anything for you.
Make sure you DO NOT overwithhold.
filing an extension will not help. when you file the extension you must go ahead and pay what you owe or you will be subject to interest and penalties when you actually file the return. changing your w4 so you get as much money each payday as possible and don’t let the govt hold your money interest free and and then get a refund will definitely help. this will be huge if many taxpayers do it.
