Do I need a Missouri-licensed CPA?+
For Missouri state filings, your preparer should hold a CPA license from the Missouri Board of Accountancy or be an Enrolled Agent. Out-of-state pros can prepare your federal return but should not sign as a CPA on Missouri returns. Missouri has a graduated personal income tax topping at 4.7% and a 4% corporate income tax.
What is self-employment tax?+
It's the self-employed equivalent of Social Security and Medicare taxes, currently 15.3% on net self-employment earnings up to the Social Security wage base, plus 2.9% Medicare above that. As a sole proprietor, you pay both the employer and employee portions.
Do I need to make quarterly estimated tax payments?+
Generally yes, if you expect to owe $1,000 or more in tax for the year. Payments are due mid-April, mid-June, mid-September, and mid-January. Missing them can trigger underpayment penalties even if you pay in full by the filing deadline.
What can I actually deduct as a sole proprietor?+
Ordinary and necessary business expenses: supplies, software, a portion of home office costs, business mileage, professional services, and more. The key is that expenses must be both ordinary for your type of work and directly related to earning income.
Should I form an LLC as a sole proprietor?+
An LLC adds liability protection but doesn't change your taxes by default — it's still reported on Schedule C. Consider it once you have meaningful liability exposure or plan to bring on partners, employees, or investors.
At what point should I hire an accountant instead of using tax software?+
Once you have real deductions to track, owe self-employment tax, or are unsure about quarterly payments, an accountant's fee is usually offset by deductions found and penalties avoided.
