Frequently Asked Questions About Entities and Small Business Tax
Short, plain answers to the questions small business owners ask most about entities, S-corps, payroll, deductions, retirement plans, and taxes, each linked to a full guide. Answers are general and hedged, because rules and thresholds change.
Is an S-corp a type of company?
No. An S-corp is a federal tax election that an eligible corporation or LLC can make. The legal entity is formed under state law, and the S election changes how the IRS taxes it. See LLC vs S-corp vs C-corp.
Does an LLC protect my personal assets?
Generally it separates the company's debts from your personal assets, but not from your own negligence, personal guarantees, certain unpaid payroll taxes, or an LLC that is not run separately in practice. Insurance fills many of the gaps. See what an LLC does and does not protect.
Does forming an LLC lower my taxes?
Not by itself. A single-member LLC is usually taxed like a sole proprietorship by default, so income tax and self-employment tax generally work the same way. Tax savings, if any, come from elections such as S-corp status. See single-member LLC taxes.
When does an S-corp election make sense?
It tends to help when an owner-operated business has steady profit comfortably above a reasonable salary, because profit beyond salary is not subject to self-employment tax. It can backfire when profit is thin or state taxes and compliance costs are high. See when to elect S-corp status.
How do I elect S-corp status?
An eligible entity files Form 2553 with all shareholders' consent, generally within two months and 15 days of the start of the tax year the election should take effect. Relief exists for some late filings. See the Form 2553 guide.
What is reasonable compensation for an S-corp owner?
It is roughly what the business would pay someone else to do the work you do. There is no fixed percentage, and you should document how you arrived at the number. See S-corp reasonable compensation.
Can I take only distributions and no salary from my S-corp?
If you perform services, generally no. The IRS can recharacterize distributions as wages, which can lead to back payroll taxes and penalties. See setting your owner salary.
What is the difference between a draw and a distribution?
Draws are withdrawals by owners of sole proprietorships, disregarded LLCs, and partnerships. Distributions are payments to S-corp shareholders in proportion to ownership. Neither is wages, and neither is a deductible expense. See owner draws vs distributions.
Do I need an operating agreement for a one-person LLC?
Many states do not require one, but it is strongly recommended. It documents that the LLC is separate, satisfies banks, and provides a plan for incapacity or death. See the single-member operating agreement guide.
Should I form my LLC in Delaware, Wyoming, or Nevada?
For most owner-operated businesses, forming in the state where you operate is simpler and often cheaper, because you must register there anyway. Out-of-state formation makes more sense for investor-backed companies or special legal needs. See forming in Delaware or your home state.
What does a registered agent do?
A registered agent receives legal papers and official state notices for your entity at a physical address in the state. You can serve yourself if you qualify or hire a commercial service. See the registered agent guide.
Do I have to pay for an EIN?
No. The IRS issues EINs free of charge. Third-party sites that charge fees are optional services. See getting an EIN.
Do I need to file a beneficial ownership report?
The rules have changed repeatedly. In 2025 FinCEN narrowed the requirement so that entities formed in the United States were generally exempted, but you should verify the current status on FinCEN's official site. See beneficial ownership reporting.
How do I separate personal and business finances?
Open a business account and card in the entity's name, run all business activity through them, and pay yourself by documented draws, distributions, or payroll. See separating personal and business finances.
What is an accountable plan?
A written reimbursement policy that meets three IRS tests (business connection, substantiation, and return of excess advances) so that reimbursements to employees, including S-corp owners, are not taxable wages. See the accountable plan guide.
Can I deduct a home office?
Self-employed people can if part of the home is used regularly and exclusively as a principal place of business. Employees, including S-corp owner-employees, generally cannot deduct it personally, so the company reimburses under an accountable plan. See the home office deduction guide.
Standard mileage or actual expenses for my vehicle?
Both are allowed, but you generally need a contemporaneous log of business miles either way. The standard rate was 70 cents per mile for 2025. Commuting is not deductible. See vehicle deductions.
Can I hire my spouse or my children?
Yes, if they do real work for reasonable pay and are treated as employees. Payroll tax exemptions for children can apply in a parent-owned sole proprietorship or partnership. See hiring family members and hiring your children.
Which retirement plan is best for a business owner?
It depends on whether you have employees, your income, and your entity type. Solo 401(k) plans often allow higher contributions at moderate income, while SEP IRAs are simpler and can be opened later. See solo 401(k) vs SEP IRA.
Do S-corp owners get a smaller retirement contribution?
Contributions are based on W-2 wages, so a low salary limits employer contributions. Salary and retirement planning should be decided together. See retirement plans for S-corp owners.
What is the QBI deduction?
A deduction of up to 20 percent of qualified business income for many pass-through owners, with limits at higher incomes for wages, property, and specified service businesses. See the QBI deduction guide.
How do estimated taxes work?
Owners generally pay income and self-employment tax quarterly. Paying at least 90 percent of this year's tax or 100 percent of last year's (110 percent above a higher income level) generally avoids underpayment penalties. See the estimated taxes guide.
Do I owe sales tax in other states?
Possibly. Since the 2018 Wayfair decision, states can require remote sellers to collect tax once they pass economic thresholds, often measured by sales or transaction counts. See sales tax nexus basics.
Does hiring a remote employee create tax obligations in their state?
Often it does, including withholding and unemployment registration, and sometimes income tax nexus and foreign qualification. See state income tax and remote employees.
Is a contractor agreement enough to make someone a contractor?
No. Classification depends on the real relationship, including control, financial arrangements, and how the parties operate. See contractor vs employee.
Should I put real estate in my S-corp?
Advisers commonly caution against it because getting appreciated property out can trigger gain. A separate LLC that leases to the operating company is a common alternative. See owning your building in a separate LLC.
Are series LLCs a good way to hold several properties?
They exist in some states but carry open questions about recognition in other states, lenders, and tax treatment. Many advisers prefer separate LLCs for valuable assets. See series LLC explained.
Is a holding company worth it for a small business?
Sometimes, when you have valuable assets to separate from operating risk or several businesses. It does not by itself reduce taxes. See holding company basics.
What is the difference between an asset sale and a stock sale?
In an asset sale the buyer picks assets and generally gets a stepped-up basis. In a stock or equity sale the buyer takes the entity with its history. Sellers and buyers often prefer opposite structures. See asset vs stock purchases.
How should a marketing agency treat client ad spend?
It depends on whether the agency acts as principal or agent, which affects gross versus net revenue reporting and credit risk. Having clients own their ad accounts simplifies matters. See agency ad spend: gross vs net.
What if my books are years behind?
Start by pulling IRS and state account records, gather bank statements, prioritize payroll and sales tax issues, then rebuild the books and file. See catching up on books and returns.
How do I close a business properly?
Approve the decision, settle liabilities, file final tax returns, close payroll and sales tax accounts, distribute remaining assets, and file dissolution with the state. See dissolving an LLC.
