Tax filing is what happens after the year closes. You gather all your income and expenses, fill out the forms, and report what you owe or what you’re getting back. By the time you file, the numbers are locked. You’re documenting what already happened.

Tax planning is what happens during the year, while you still have time to change the outcome. It’s the work of looking ahead at your income and making decisions that legally lower what you’ll owe when filing arrives.

The levers available through planning are varied. Timing of income and expenses is one of the most powerful. If you’re having a big year, you might delay sending an invoice until January so that income lands in next year. Or you might accelerate a large purchase into December to take the deduction this year. Timing decisions shift income and deductions between years to manage your bracket.

Retirement contributions are another big one. A SEP IRA or Solo 401(k) lets you put away significant money before taxes. The contribution limits are generous for self-employed owners. But you need to know your projected income to decide how much to contribute and when.

Equipment and vehicle purchases can often be deducted immediately under Section 179 instead of depreciating over time. But it only helps if you need the deduction this year and have the cash flow to make the purchase. Entity structure and compensation also play a role. If you’re operating as an S-corp, the split between your salary and distributions affects your self-employment tax. These decisions get made during the year and have real impact on your bill.

Then there are deductions that are easy to miss. Home office, vehicle use, professional development, and health insurance premiums are all deductible but often overlooked if nobody is looking at your full picture during the year.

The value of working with a CPA and Enrolled Agent who also handles your small business bookkeeping is that the planning stays continuous and grounded in your actual numbers. Simona sees your income and expenses in QuickBooks Online every month. If you’re on track for a much bigger tax bill than expected, that shows up mid-year when there’s still time to act. Planning based on real data beats guessing from last year’s return.

This is what tax strategy looks like in practice. Filing reports what happened. Planning affects what happens next.
