How Business Owners Legally Reduce Their Taxes: 8 Proven Strategies

Most business owners overpay the IRS, not because their return was filed wrong, but because no one built a plan during the year. Tax preparation records what already happened. Tax planning changes the outcome before the year closes. Below are eight of the strategies our clients use most, the same ones that help the average Tax Square client keep an extra $24,000+ every year.

This is an overview, not personalized advice. The right mix depends on your income, entity, and goals, which is exactly what a tax strategist is for.

1. Choose the right entity structure

How your business is taxed often matters more than how much it earns. A default LLC pays self-employment tax (15.3%: 12.4% Social Security + 2.9% Medicare) on all of its net profit. Electing S-Corp status lets you split income between a reasonable salary (subject to payroll tax) and distributions (not subject to self-employment tax), which can save thousands once your profit is consistent. See our full breakdown in S-Corp vs LLC in Texas.

2. Pay yourself a reasonable salary (and no more)

If you elect S-Corp status, the IRS requires a "reasonable" salary for the work you do, but everything above that can flow through as a distribution that avoids the 15.3% self-employment tax. Setting that salary correctly is where a strategist earns their fee: too low invites an audit, too high leaves money on the table.

3. Use the Augusta Rule (Section 280A)

You can rent your personal home to your business for up to 14 days a year, and that rental income is completely excluded from your personal income, while the business deducts it as a legitimate expense. It has to be documented and priced at a fair market rate. Full details in The Augusta Rule Explained.

4. Take a legitimate home office deduction

If you use part of your home regularly and exclusively for business, you can deduct a proportional share of rent or mortgage interest, utilities, insurance, and depreciation. For S-Corp owners, this is usually handled through an accountable reimbursement plan rather than a Schedule C line.

5. Fund a business retirement plan

A SEP-IRA or Solo 401(k) lets business owners contribute far more than a standard IRA, and those contributions are generally deductible, lowering taxable income today while building wealth for later. For higher earners, this is often the single largest deduction available. (Annual contribution limits are set by the IRS and adjusted each year.)

6. Time equipment purchases with Section 179 and bonus depreciation

Section 179 and bonus depreciation let you deduct the cost of qualifying equipment, vehicles, and technology in the year you place it in service, instead of spreading it over many years. Timing a planned purchase into the right tax year can meaningfully lower what you owe.

7. Put your family on the payroll (correctly)

Employing your children or a spouse for real work at a reasonable wage can shift income to lower brackets and, in the right structure, reduce payroll tax exposure. The work has to be genuine and documented, but done right, it keeps money in the family instead of sending it to the IRS.

8. Capture the QBI deduction

The Qualified Business Income (QBI) deduction can let owners of pass-through businesses deduct up to 20% of their qualified business income. Income thresholds and business-type limits apply, and how you structure salary versus distributions directly affects how much QBI you keep. Read The QBI Deduction Explained.

The common thread: plan ahead, all year

None of these strategies work if you only think about taxes in April. They work when someone models them before the year ends and implements them through your books month by month, which is exactly how we run the Tax Square relationship: planning, accounting, and preparation as one coordinated engagement.
