5 ways to cut your 2025 tax bill while there’s still time
Year end planning works because timing is a tax tool. Using it intentionally creates cleaner books, lower liability and better flexibility heading into 2026.
The final weeks of 2025 are the last chance for small and mid-size businesses to shape their tax position for the current year.
Congress reset the rules for depreciation and expensing. Accounting method choices are more flexible than many assume. S Corp treatment still offers planning room even late in the year.
These moves directly influence 2025 taxable income and 2026 cash flow.
The Law in Play
The core provisions are §168(k) for 100% bonus depreciation, §179 for expanded expensing, the accounting method rules under § § 446 and 448, S Corp rules under Form 2553, and the pass-through deduction under §199A.
The question is how to use timing, wages, and entity classification to lower tax liability without creating later issues. The IRS accepts these strategies as long as they are supported by clear records and placed in service before the end of the year.
