If you file a Schedule C, the amount of income you report on your Form 1040 isn’t the whole story. Adjusted Gross Income (AGI) determines eligibility for many credits, deductions, and phase‑outs that can meaningfully affect your tax bill. Understanding the adjustments that directly lower AGI can help you stay compliant while keeping more of what you earn.

Half of the Self‑Employment Tax Is Deductible

When you calculate self‑employment tax, you first compute the net earnings from self‑employment and then apply the 15.3 % rate. The IRS allows you to deduct half of that self‑employment tax as an “above‑the‑line” expense when figuring AGI. This deduction is taken on Schedule 1, line 27, and it reduces the amount of income subject to income tax, even though the full self‑employment tax still must be paid. By lowering AGI, the deduction can also make you eligible for other income‑based benefits, such as the Premium Tax Credit for health insurance.

Health‑Insurance Premiums for the Self‑Employed

Self‑employed individuals can deduct the cost of health‑insurance premiums paid for themselves, their spouse, and dependents. The deduction is reported on Schedule 1, line 16, and it directly reduces AGI. To qualify, the policy must be established under your business and you cannot be eligible to participate in an employer‑sponsored plan. This adjustment not only lowers your taxable income but also can bring your AGI below thresholds that trigger phase‑outs for deductions like student loan interest or the deduction for traditional IRA contributions.

Other Adjustments That Can Shrink Your AGI

Beyond taxes and health costs, several everyday business expenses can lower AGI when claimed on Schedule C or Schedule 1. A home office that meets the exclusive‑use test allows you to deduct a portion of rent, utilities, and internet. Even modest items, such as a $100‑a‑year Ring security camera used to protect a home‑office setup, qualify as ordinary and necessary business expenses.

Mileage remains a popular deduction for gig drivers. For 2026 the standard mileage rates are $0.725 per mile for January–June and $0.76 per mile for July–December. You may choose the standard mileage method or actual vehicle expenses; the standard rate simplifies record‑keeping while still reducing your net earnings and, consequently, your AGI.

Retirement contributions also affect AGI. Roth contributions can earn the Saver's Match, but the match payment itself cannot be deposited into a Roth IRA (26 U.S.C. 6433(e)(2)(A)(ii)). While the Roth contribution itself does not lower AGI, making traditional IRA contributions up to the allowable limit does, and the resulting lower AGI can unlock additional tax benefits.

The IRS code sucks. We simplify it.
