Whether you’re a salaried executive with RSUs, an entrepreneur, or an investor with rental properties in more than one state, Fusion CPA looks at the full picture. We integrate your personal 1040 and business returns into one strategy, to optimize tax opportunity and avoid surprises.
Pick the stage that matches your situation today, and you’ll see exactly how we handle it.
Schedule C Setup & First Filing
The IRS generally treats a single-member LLC as a disregarded entity, so your business income is typically reported on Schedule C of your personal 1040. We set you up with the right bookkeeping categories and identify every deduction you qualify for, then make sure your first filing is done right.
EIN & Business Separation
An EIN, the federal Employer Identification Number the IRS uses to identify your business, isn’t required for a solo SMLLC, but we recommend getting one anyway. It makes banking and vendor contracts easier. It also keeps your business and personal finances separate.
Quarterly Estimated Payments
If you expect to owe $1,000 or more, quarterly payments are required. We calculate each one based on your actual income, so you never overpay or get hit with a penalty.
Deduction Identification
Home office, vehicle, health insurance, professional development, software, travel, meals: we walk through every deduction you qualify for from the start, so nothing gets missed.
S-Corp Election Analysis
When net income consistently exceeds $60K to $80K, an S-Corp election may reduce self-employment tax. We model the break-even for your specific numbers, including payroll costs, compliance overhead, and reasonable compensation. The right answer depends on your facts and circumstances.
Entity Restructuring Roadmap
Adding a business partner converts your SMLLC into a partnership automatically, whether or not that was the plan. Bringing on outside investors usually points toward a C-Corp instead. We build the transition plan, covering the timing, asset transfers, and state filings that come with either path.
Retirement Contribution Maximization
A SEP IRA lets you contribute up to $72,000 for 2026, which can shelter a large chunk of income if your net earnings support it. A Solo 401(k) or SIMPLE IRA might fit your cash flow better. We evaluate which plan actually maximizes your deduction.
QBI Deduction Optimization
The Qualified Business Income deduction under Section 199A lets you deduct up to 20% of your qualified business income from your taxable income. Eligibility depends on income thresholds, business type, and W-2 wage limitations.
Compensation vs. Distribution Modeling
We model the optimal salary-to-distribution split that minimizes SE tax while maintaining a reasonable compensation position. Too low triggers IRS scrutiny; too high wastes the benefit.
Form 2553 Filing & Payroll Setup
We file the S-Corp election with the IRS and set up payroll for your reasonable compensation. From there, we manage the transition from Schedule C to a coordinated 1120-S and 1040 filing.
1120-S + 1040 Coordination
Once elected, we prepare your S-Corp return and personal return together. Compensation, distributions, your K-1 (the form reporting your share of the S-Corp’s income), and retirement contributions are optimized across both returns.
Compliance Requirements
S-Corp status adds payroll tax filings, reasonable compensation documentation, and stricter record-keeping. We handle all compliance so the tax savings are not offset by audit risk.
State Filing Obligations
Earning income in multiple states, or simply selling to customers across state lines, can trigger a filing requirement somewhere you weren’t expecting. We track where those obligations start and file everywhere you owe.
State Income Tax Optimization
Each state has different tax rates, deduction rules, and filing thresholds. We identify where you can minimize exposure and coordinate your federal and state filings.
Resident vs. Nonresident State Filings
The state where you live taxes all of your income, no matter where your clients are. If you also do work while physically present in another state, that state may require a nonresident return too. You typically get a credit for tax paid there, so the same dollar doesn’t get taxed twice.
Sales Tax: Referral
Selling products or certain services can create sales tax registration obligations in states where you do business. That area sits outside our scope, so we will flag the exposure and point you to a specialist or the relevant state Department of Revenue, while we handle your income tax filings.
If any of these sound familiar, your SMLLC tax strategy needs a closer look.
Every dollar of net income on your Schedule C gets hit with the full 15.3% self-employment tax, plus income tax. That’s true whether or not it’s the smallest bill you could legally owe. Most owners pay that same rate year after year. Nobody ever checks if a retirement contribution or an entity election would help, quietly leaving real money on the table.
Your return gets filed the same way every year, same categories, no real review, so deductions quietly go unclaimed. Home office costs and health insurance premiums are common misses simply because nobody asked. A missed retirement contribution is usually the costliest one, since it also lowers your self-employment tax base for the year.
Guess too high and you’ve handed the IRS an interest-free loan. Guess too low and a penalty shows up next April. Most SMLLC owners are estimating off last year’s number instead of what they’re actually earning today, so the guess is wrong before the check even gets written.
If your net income has cleared the point where an S-Corp election pays off, every year without one costs you. You’re overpaying self-employment tax you didn’t have to. Most owners have heard the general rule of thumb, but never got a break-even calculation built around their own numbers. So they don’t know whether waiting is costing them money right now.

How We Approach SMLLC Tax Planning
Explore the common filing structures below to see when each may apply and how Fusion CPA coordinates your business and personal tax requirements.
A freelance developer was already past the point where an S-Corp election starts to pay off. We ran the reasonable-compensation numbers against the added payroll cost and recommended waiting one more year, until the math clearly worked in their favor.
A real estate agent had been using the standard mileage rate without ever comparing it to actual expenses. Switching methods and documenting it properly recovered a deduction they had been leaving on the table for years.
Once a consulting SMLLC crossed its break-even point, we shifted the conversation to compensation strategy and quarterly estimates. We modeled the salary-to-distribution split around actual numbers instead of a generic percentage.
A freelancer split time between two states and took on clients in both. We sorted out where each dollar of income was actually earned and made sure the resident-state credit applied correctly, so nothing got taxed twice.
Scenarios are illustrative composites drawn from common SMLLC engagements and are anonymized. They describe situations we work through, not promised outcomes; results depend on each business’s specific facts.
Every engagement starts with a complimentary Discovery Call. We talk through your SMLLC, your current income level, and your deduction situation. You'll get initial recommendations before any commitment.
We review your prior returns and financial records, then catch missed deductions and misclassifications. Anything that needs amending gets corrected before we build your strategy.
With your foundation in place, we build your tax strategy. That includes a reasonable compensation recommendation if you're S-Corp eligible, plus a distribution plan. We also build a quarterly estimate schedule and a retirement contribution plan around your numbers.
We check in regularly to adjust your strategy as your income changes. At year-end, we prepare a Schedule C with your 1040 if you haven't elected S-Corp, or a coordinated 1120-S and 1040 with K-1s if you have. Either way, you're positioned for the year ahead.

Frequently Asked Questions
By default, the IRS treats a single-member LLC as a disregarded entity. Your business income is reported on Schedule C of your Form 1040. Net earnings are generally subject to income tax plus a 15.3% self-employment tax. That breaks down to 12.4% for Social Security and 2.9% for hospital insurance under IRC Section 1401(b). You can also elect S-Corp treatment, which may reduce the self-employment tax portion depending on your facts and circumstances.
It depends on your numbers. An S-Corp election is typically worth analyzing once net income consistently runs $60,000 to $80,000 or more. At that point, income can be split between salary and distributions. One of the most common mistakes we see is electing too early, when the added payroll and compliance costs outweigh the tax benefit. We model the break-even for your specific situation before recommending a change.
Common deductions include the home office, vehicle expenses, and health insurance premiums. You can use retirement contributions such as a SEP IRA or Solo 401(k), plus the 20% Qualified Business Income deduction. Business supplies, travel, and a portion of meals count too. Eligibility for each depends on your specific circumstances, so we review your situation before applying any of them.
