Tax planning isn’t something you should wait until tax season to think about. Most of the moves that will actually lower your bill happen long before the year ends. Once the year is over, those opportunities are gone. A few strategies worth keeping in mind for this year:

✅ Max out retirement contributions before the end of the year.
✅ Time large or deductible purchases to the year they’ll help you most.
✅ Defer or accelerate income depending on how your year unfolded.
✅ Review your estimated payments and withholding so you’re not blindsided.
✅ Revisit your business structure if your income has changed.

John J Griffin CPA P.C. offers tax planning in Chicago that keeps moves like these on your radar all year long, so you don’t find yourself approaching your deadline wishing you had acted sooner.

You can fill out your return flawlessly, file right on time, and still overpay. Many individuals don’t know this distinction: preparation makes sure what you file is accurate; planning shapes what you actually owe before the year is over.

The decisions that move your bill happen long before you even file. It involves how and when you take income, what you put toward retirement, how you time big expenses, and what you set aside, all year long. Fail to plan ahead, and your window to do anything about it closes when the year ends.

At John J Griffin CPA P.C., we offer tax planning in Chicago that helps you make smart decisions all year long so you owe less by the time filing season arrives.
