Maximize Write-offs. Eliminate quarterly tax surprises.

Anything necessary and ordinary for your operations — including home office square footage, software platforms, hardware, and work-related travel. Our system automatically scans your synced bank feeds, matching transactions against overlooked deduction opportunities to minimize your net taxable income.

Yes. Our business advisory specialists evaluate your net earnings to determine when an S-Corp entity optimization will save you more in self-employment taxes. We then handle the restructuring framework, payroll setup, and corporate tax compliance.

A common guideline is 25–30% of your gross 1099 income, but your exact number depends on your total income, filing state, deductions, and filing status. Our Self-Employment Tax Surprise Estimator and Quarterly Estimated Tax Planner calculate your precise figure in real time — including the 15.3% SE tax, federal income tax, and state tax — so you save exactly what you owe, not a penny more or less.

Your W-2 withholding can actually reduce your quarterly estimated payment burden, but only if it's calculated correctly. We blend both income streams into a single tax projection, adjusting your W-4 withholding and quarterly payments together so you avoid both underpayment penalties and unnecessary overpayment. We also ensure your side income doesn't push you into a higher bracket without warning.

Both let you shelter income from taxes, but they differ in contribution limits and flexibility. A Solo 401(k) generally allows higher contributions at lower income levels because it includes both an employee deferral and an employer match, while a SEP IRA is simpler but capped at 25% of compensation. Our Individual 401(k)/SEP IRA Contribution Planner models both side by side for your exact income, and we help you open and fund the right account before the deadline.

You can use your SSN as a sole proprietor, but we often recommend obtaining an EIN — it's free, protects your SSN from identity theft, and is required if you ever hire employees or open a business bank account. We walk you through the one-step IRS registration and help you decide whether your business structure warrants one based on your growth plans.

The IRS charges underpayment penalties calculated on the shortfall, compounded daily — but the damage is reduced the sooner you catch up. If you miss a deadline, we immediately recalculate your remaining quarterly payments to cover the gap, assess whether you qualify for safe-harbor exceptions (like owing less than $1,000 or 90% of last year's tax), and file Form 2210 to request a penalty reduction where applicable.
