Beginner's Guide to Small Business Tax Deductions

Both new and experienced small business owners can agree that the topic of taxes can be intimidating, regardless of how much experience one has. One of the main concerns business owners have is tax deductions – how to claim them and ensure that they are taking advantage of all the deductions available to them.

We'll cover the different types of deductions available to small business owners, including home office expenses, mileage deductions, and more. By understanding these deductions and how to claim them, you can reduce your tax burden and free up more money for reinvestment in your business.

How Small Business Tax Deductions work

Small business tax deductions work by reducing the amount of income that is subject to tax. In other words, they allow business owners to lower their taxable income by claiming deductions for certain expenses. While not everything is considered a tax write-off, eligible expenses can result in a lower tax bill and more money in the business owner's pocket. Here are a few examples of common applications of mall business tax deductions

  • Home office deduction: Using part of your home just for your business, may qualify for home office deduction. This means you can deduct a part of your rent or mortgage, utilities, and other home expenses based on the percentage of your home you use for your business.
  • Mileage deduction: If you use your personal vehicle for business purposes, you may be able to claim your business miles. This allows you to deduct a certain amount of cents per mile you drive for business purposes. Let’s say you drive 1,000 business miles in a year and the current mileage deduction rate is $0.585 per mile, you can claim a deduction of $585.
  • Equipment and supply expenses: If you purchase equipment or supplies for your business (which you likely do), you may be able to claim a deduction for these expenses as well. For example, if you buy a new computer for your business, you can claim a deduction for the cost of the computer.

Quick Tip

It’s important to keep good records (receipts, mileage log, etc.) throughout the year to track all of your business expenses. While every expense doesn’t require receipts to apply the deduction, having them handy is always the best practice.

Tax Deductions vs. Tax Credits

A tax credit is a directly proportional way to reduce your tax bill. For example, if you have a $1,000 credit, it will reduce your tax bill by $1,000. A deduction is different – It reduces the amount of money you have to pay taxes on. Let's say you're self-employed and have an LLC. You might be able to claim a deduction for using a home office. If you have $50,000 in taxable income and claim a $1000 home office deduction, your taxable income will go down to $49,000. That means you'll pay less in taxes. Keep in mind, there might be limits or rules about when you can claim deductions. Let's look at some below.

Common Tax Deduction Rules to Know

The rules we referred to above are the limitations or “phase-outs” that may apply to deductions.

  • Limitation: A limitation on a deduction means that there is a maximum amount that you can claim.
    • Example: There may be a maximum amount that you can claim for charitable donations in a single tax year.
  • Phase-Out: A phase-out of a deduction means that the value of the deduction decreases as your income increases until it is eliminated completely.
    • Example: For example, if you are eligible for a $1000 deduction for using a home office, but there is a phase-out for this deduction that starts at $50,000 of income, the value of the deduction will be reduced until it is no longer available at a certain income level.

Don't get tripped up by deduction rules. They are there to ensure deductions are only used for people who really need them. (Otherwise, it opens the system up for abuse). Always check with a tax pro or the IRS to understand any limits or special rules that might apply to the deductions you're thinking about claiming.

How to get a Tax Deduction for Your Small Business

Here are three steps to getting a tax deduction for your small business:

Keep accurate records: Make sure to keep detailed and organized records of your business expenses throughout the year. This will make it easier to claim deductions on your tax return. Most business owners find it easier to automate this task using accounting software or bank integrations to log their receipts.

Know what is deductible: Not all expenses are tax-deductible, so it's important to understand what is and what isn't eligible. You can refer to IRS guidelines or consult with a tax professional to determine what deductions you may be able to claim.

Claim the deduction: When it's time to file your tax return, make sure to claim the deductions you are eligible for. You will need to provide documentation of some of your expenses, so be sure to have your records on hand. You can claim deductions on the appropriate forms or schedules of your tax return (we’ll discuss where to get those), depending on the type of expense.

Forms and Schedules for Business Tax Deductions

Again, these forms and schedules for claiming deductions will all depend on the type of expense and your business structure. For example:

  • Sole proprietors and single-member LLCs: You will claim your deductions on Schedule C (Form 1040), Profit or Loss From Business.
  • Partnerships and multi-member LLCs: You will claim your deductions on Form 1065, U.S. Return of Partnership Income.
  • Corporations: You will claim your deductions on Form 1120, U.S. Corporation Income Tax Return.

There are also other forms and schedules that may be applicable depending on the type of expense, such as Schedule A (Form 1040) for itemized deductions or Form 4562 for depreciation.

You can find PDF copies of these forms and schedules on the IRS website. You can search for the form or schedule by name or number. Remember, the IRS updates tax codes annually depending on inflation and government changes, check the website for any updates or changes to the forms before you file your tax return.

Maximizing Small Business Tax Deductions

To maximize your tax deductions and reduce the burden of business taxes, it's important to be knowledgeable about the available deductions and to keep good records. This includes understanding what deductions you are eligible for and organizing your records to reflect those expenses. By following these best practices, you can expect to see a lower tax bill.
