What is a Tax Deduction? 

A tax deduction, also known as a tax write-off, is a business expense that you can subtract from your taxable income and make your tax bill smaller. The IRS has specific criteria about what counts as a tax deduction. Keep reading and we’ll break down some of the most common ones. For information specific to you and your business, contact a local tax professional. 

Types of Small Business Taxes

The taxes a small business pays depends on the business structure. Here are the five small business taxes that all structures have in common. 

Income Tax

All businesses except partnerships file annual income tax returns. Partnerships file information returns instead. 

Self-Employment Tax

The tax on your net earnings from self employment that go towards social security and medicare obligations. 

Employment Taxes

Taxes related to your employees’

  • Social security and Medicare taxes
  • Federal income tax withholdings
  • Federal unemployment tax

Payroll taxes also fall into this category.

Excise Tax

Excise taxes are special, industry-specific taxes. For example, fuel, tobacco, and alcohol taxes. The reasons for needing to pay an excise tax cuts across several categories, including:

  • The types of products or services you sell
  • The type of business you operate
  • The type of equipment you use

Estimated Taxes

Sole proprietorships, partnerships, S-corp shareholders, and other businesses that don’t have taxes withheld from their paychecks are required to make quarterly estimated tax payments.

Things to Remember

Here are a few things small business owners should keep in mind before they file their taxes for the first time as a business. 

Tax ID Number

You will need your tax ID number to file your tax return. For corporations and LLCs this is the Employer Identification Number. For sole proprietors and partnerships this is a social security number. 

15.3% Self-Employment Tax

In addition to your income taxes, self-employed individuals owe 15.3% in self-employment tax. This is the percentage that employers normally deduct from employees’ paychecks for Medicare and Social Security. 

Don’t Forget Cash Payments

You need to report all of your income, including cash payments, on your tax return. 

You Can File For an Extension

Filing an extension is an option if you’re not ready to submit by April 15th. The extension filing deadline is March 15th for S-Corps and April 15th for C-Corps. Even if you get an extension, you should pay your estimated taxes to avoid penalty and interest charges.

Employee Bonuses 

Employee bonuses are taxed differently from employee wages. They come with a 22% bonus tax and a different tax rate for Social Security and Medicare. 

Side Hustle Income 

The IRS considers supplemental income from side gigs to be self-employment income and is taxed accordingly.

Recent Changes to Tax Laws

The 2018 tax reform law stemmed a few changes that it’s important for new small business owners to keep in mind. You don’t necessarily need to understand all of the entails, but having a basic understanding while you work with a tax professional can help you get on the same page about your tax process. 

State and Local Tax (SALT) Cap

As of 2020, you can only deduct up to $10,000 in state and local income and property taxes. 

Deduction for Pass-Throughs and Corporations

The tax reform law also offers a 20% deduction for pass-through and corporation business entities. Pass-through business is a tax term for small businesses structured as sole proprietorships, partnerships, LLCs, and S-corps. These make up 95% of US businesses. However, there are limitations for service-based business owners who make more than $157,500 as a single filer or $315,000 as a married joint filer. The tax rate for C-corps was also lowered from 35% to 21%. 

First-Year bonus Depreciation

The law also changed the first-year bonus depreciation deduction to 100%. That means eligible property and equipment purchases can be written off completely instead of writing off a portion of the purchase price each year.

The Most Common Tax Deductions for Small Business

Self-Employment Tax Deduction

If you pay the self-employment tax, you can deduct half of the amount that you pay for it from your net income when you calculate your income tax. This is because the IRS treats the employer’s portion of the self-employment tax as a business expense. 

Startup Costs

For most major expenses, the IRS requires businesses to deduct them over time as opposed to all at once. The biggest exception to this is the startup costs deduction. You can deduct up to $5,000 in these costs during the first year of actively running your business. Deductible startup expenses include:

  • Market research
  • Travel expenses related to starting your business
  • Advertising
  • Attorney and accountant fees

Here are a series of small business tax deductions related to your workspace. 

Business Property Rent

If your office space is rented, you can deduct the money you pay from your taxes. If you run your business from home, you can run an eligibility test with the IRS to see if you qualify to deduct your rent. However, you can’t deduct rent expenses on properties that you own. 


Similarly, you can deduct any utilities that you pay for your business. This includes, but is not limited to:

  • Water
  • Electricity
  • Trash
  • Phone and internet

Home Office Expenses

If you operate your business from home, you can also qualify for deductions associated with those expenses. These are the requirements your home office needs to meet to qualify for a deduction:

  • Work area must be only used for business activities
  • Work area must be your primary place of business
  • The majority of the time you spend in the area must be business use
  • You have no alternative workspace, such as an office outside the home or a coworking space. 

There are two ways to calculate your home office deduction: the simplified method and a regular method. 

Simplified Method

Deduct $5 per square foot of your home that you use for business purposes, up to 300 square feet. 

Regular Method

Calculate the percentage of your home’s square footage you use for business purposes and apply that percentage to your home expenses. 

Whichever method you use, make sure you have proof of the information you provide. The IRS scrutinizes home office expenses very carefully.

Coworking Space

If you rent a coworking space where your membership fees contribute to the cost of rent and utilities, those fees could be a tax deductible expense. 

Improvements and Repairs

Repairs to your business property or home office that are necessary for continuing to work there can be deducted from your taxes. You can also write off improvements to your home office, but they must be depreciated. Talk to your accountant before you pay for an improvement or repair to make sure you can deduct it.

Office Supplies and Furniture

Expanding your knowledge to improve your business is always a worthwhile investment. It only makes sense to deduct it from your taxes. If you or your employees take a class, attend a seminar, or subscribe to a trade publication that improves your skills in a way that’s relevant to your business, you can deduct the costs. 

It doesn’t even have to be directly related to your primary products or services. For example, taking a photography class so you can take better product photos would count because it improves your day to day operations.

Small Business Tax Tips

Here are a few tips for people who are new to paying taxes as a business owner. 

Always Keep Your Receipts

You’ll notice a theme in many of these types of deductions: keep the receipts to prove that you made the purchase and that it was for business purposes. As you make your purchases, file every receipt into an organized system so you can easily find them when it’s tax preparation time. 

Think About Taxes All Year Long

Tax planning shouldn’t be a once a year event. Thinking about your taxes all year round makes tax time less complicated and helps you save money more effectively.

Pay Attention to Changes in Tax Law

Even if you have a professional preparing your taxes, it’s a good idea to stay informed about changes in tax laws so you don’t get any surprises. 

Don’t Assume

You should never make business decisions under the assumption that you’ll get a particular tax break. 

Consult With a Professional

If you have any doubts about whether or not something counts as a tax deduction or if you’re applying the right amount of tax for a deduction, ask a CPA or other tax professional. It’s always better to ask for a professional opinion than to make the wrong decision and get audited.
