Understanding how small business taxes work makes running your business a lot easier. Tax rules are often tricky, especially when you’re just starting. Below, we’ll walk you through the basics. This way, you can plan ahead, stay organized, and avoid surprises during tax season.

What Taxes Do Business Owners Pay?

If you have a business, you might be paying a few types of taxes. These can vary based on your setup. However, most small business owners deal with some combination of income tax, self-employment tax, employment tax, and sales tax.

Type of Tax Who Pays It What It Covers
Income Tax All businesses (varies by structure) Tax on the business’s profits, reported differently based on entity type
Self-Employment Tax Sole proprietors, partners, single-member LLCs Covers Social Security and Medicare contributions for self-employed individuals
Employment Tax Businesses with employees Includes withheld income tax, Social Security, Medicare, and federal unemployment
Sales Tax Businesses selling taxable goods/services State/local tax collected from customers at the point of sale

Tax Rates and Filing Requirements by Entity Types

Your tax situation depends mostly on how your business is set up. Each type of business entity has its own forms, deadlines, and rules. Below is a breakdown of how taxes work for common setups.

Sole Proprietorships and Single-Member LLCs

Do I file my LLC and personal taxes together?

If you have a single-member LLC, yes. You’ll report your business income and expenses on Schedule C, which is part of your personal tax return.

If you’re a sole proprietor or a single-member LLC, your business income gets reported on your personal tax return. You’ll use Schedule C (Form 1040) to report your income and expenses. Since the business isn’t separate from you, the IRS sees it as “flow-through” income. This means profits flow directly to your personal return.

Partnerships and Multi-Member LLCs

Partnerships and Multi-member LLCs need to file Form 1065 each year. This is an information return that shows the IRS what your business earned. Each partner receives a Schedule K-1, which shows their share of the profits or losses. You’ll use this to report income on your personal return. One thing to remember: Form 1065 is due March 15th, not in April like individual returns.

S Corporations and C Corporations

Is a single member LLC taxed as an S Corp?

Not by default. You can choose to be taxed as an S Corp by filing Form 2553 with the IRS. This may help reduce self-employment taxes if your income is high enough.

S corporations file Form 1120S, and each shareholder gets a K-1 to report their share of the income on their personal return. S Corps don’t typically pay income tax at the business level. It flows through to the shareholders. C corporations, on the other hand, file Form 1120 and pay taxes at the corporate level. If you take money out as a dividend, it could be taxed again on your personal return. 

Business Entity Tax Form Used Tax Filing Deadline Who Pays the Tax Flow-through or Separate Entity?
Sole Proprietorship Schedule C (Form 1040) April 15 Owner (on personal return) Flow-through
Single-Member LLC Schedule C (Form 1040) April 15 Owner (on personal return) Flow-through
Partnership Form 1065 + Schedule K-1 March 15 Partners (on personal returns via K-1) Flow-through
Multi-Member LLC Form 1065 + Schedule K-1 March 15 Members (on personal returns via K-1) Flow-through
S Corporation Form 1120S + Schedule K-1 March 15 Shareholders (on personal returns via K-1) Flow-through
C Corporation Form 1120 April 15 (or 15th day of 4th month after year-end) Corporation (at entity level); shareholders pay tax on dividends Separate Entity

When and How to Pay Business Taxes

Does a single member LLC pay quarterly taxes?

Yes, if you expect to owe at least $1,000 in taxes for the year, the IRS usually requires quarterly estimated tax payments.

Most small business owners don’t just pay taxes once a year. They often make payments throughout the year. If you expect to owe $1,000 or more in taxes, you’ll likely need to make quarterly estimated tax payments.

These are due four times a year:

  • April 15th
  • June 15th
  • September 15th
  • January 15th (of the following year)

Based on your business structure, you’ll also file an annual return once a year. For example, sole proprietors and single-member LLCs file their business income with their personal return by April 15th. Partnerships and S Corps file by March 15th.

To make payments, you can use the IRS Electronic Federal Tax Payment System (EFTPS), or you can pay online through IRS.gov.

Instead of waiting until tax season, many small business owners stay organized by making estimated tax payments every quarter. Here's how that might look in practice:

1. Calculate your expected net income for the year based on past earnings, current contracts, or revenue projections.

2. Estimate your total tax liability using tools like the IRS Tax Withholding Estimator or a small business tax calculator.

3. Divide that number by four to determine your quarterly payments.

4. Mark key IRS deadlines (April 15, June 15, September 15, and January 15) on your calendar.

5. Set aside a portion of each client payment or weekly income so you’re not scrambling before each due date.

6. Make payments using IRS.gov or EFTPS, keeping digital records of each transaction for bookkeeping.

Tax Deductions for Small Businesses

Business deductions can lower the amount of income you’re taxed on. The key is knowing what counts as a business expense and keeping track of those costs throughout the year. Below are some of the most common deductions you can make.

Operational Expenses

How much tax write off for small business?

It depends on your business expenses. You can deduct things such as office supplies, software, marketing, and more. There’s no set limit as long as the expenses are business-related.

Most of your everyday costs can be deducted. These include:

  • Office supplies like pens, paper, and printer ink
  • Business software subscriptions
  • Advertising and marketing costs
  • Professional services like bookkeeping or legal help

As long as these expenses are ordinary and necessary for your business, they typically count.

Property and Insurance Deductions

Can I write off my car payment as a business expense?

Not fully, unless your vehicle is used 100% for business. You can deduct a portion based on business use, as well as mileage or depreciation.

If you buy equipment or other business property, you might be able to deduct part or all the cost.

  • Section 179 lets you deduct the full cost of some equipment in the year you buy it
  • Bonus depreciation can also apply to certain large purchases
  • Business insurances, like general liability or professional coverage, is also deductible

Home Office & Utilities

Can I write off my electric bill if I work from home?

Yes, but only part of it. It’s based on the percentage of your home used regularly and exclusively for business.

If you work from home, you may qualify for the home office deduction. To claim it, the space must be used frequently, and only for your business. You can also deduct a portion of utilities like electricity, internet, and rent or mortgage interest (if you own a home).

LLC Fees & Startup Costs

Can I write off my LLC fees?

Yes. You can typically deduct LLC formation fees and other startup costs as part of your first-year business expenses.

Getting your business up and running costs money. However, many of those costs are deductible.

  • LLC formation fees
  • State business licenses
  • Legal and consulting fees
  • Startup costs like market research or promotional materials

You can usually deduct up to $5,000 of startup costs in your first year.

Tax Refunds and Losses: What Happens if You Don’t Profit?

Will I get a tax refund if my business loses money?

Not directly. If you’ve overpaid during the year or had taxes withheld, you might get a refund. Otherwise, losses can be used to lower your taxable income in future years.

Not every business turns a profit in its first year. That’s okay. If your expenses are higher than your income, you might be able to report a net operating loss (NOL). This means your business lost money after all deductions were accounted for. You won’t owe income tax if you didn’t make a profit, but you still need to file your return. In some cases, you may even be able to carry that loss forward to offset income in later years.

How Much Should I Set Aside for Taxes?

How much should I put aside for taxes as self-employed?

A good rule is to set aside 25% to 30% of your net income. This helps cover both income tax and self-employment tax.

One of the best things you can do as a small business owner is set aside money for taxes throughout the year. A good rule is saving around 25% to 30% of your net income to cover your income tax and self-employment tax. If you’re making estimated quarterly payments, this money can go towards those deadlines. If you’re not sure how much you should save, consulting a tax professional can give you a better idea on your earnings and expenses. 

New Regulations and Reporting Requirements

Tax rules can change every year, so it’s important to stay current. Some changes might be federal, but many come from your state. This is especially true regarding sales tax or business registration requirements.  For example, some states now require online sellers or service providers to collect sales tax, even if they don’t have a physical location there. Others may have new rules about how you report income or track expenses. Because these requirements vary so much by location, check with your state’s tax agency or work with a local tax professional who knows your area’s rules.

Free Tools and Resources for Small Business Tax Planning

You don’t have to figure it all out on your own. Plenty of free tools and resources can make tax planning easier. The IRS Small Business and Self-Employed Tax Center is a great place to start. It offers guides, videos, and tools to help you understand your tax responsibilities.  You can also use calculators to estimate deductions or credits. For example, Small Business 401(k) Tax Credit Calculator helps you see if you qualify for certain retirement plan tax credits. Taking a few minutes to explore these resources now can save you time and money later. 

Plan Ahead to Save More

Staying on top of your taxes is easier when you plan in advance. Keeping good records, setting aside money regularly, and knowing your deadlines can make a big difference at tax time. Even if you’re just getting started, it’s worth building good habits now. And if things feel unclear, talking with an advisor can help you sort through your options and ensure you’re on the right track. Want to start planning ahead now? Find your wealth manager today!
