Your Small Business Tax Deductions Checklist

The not-so-good news? Every business needs to file taxes. The great news? There are many expenses you can apply to your income to help alleviate your tax burden. These deductions will reduce your profits, meaning that you will pay lower overall taxes. While the IRS does not specifically list what you can claim, they do state that if a cost you’ve incurred is “ordinary and necessary” to running your business, then you can deduct it.

We’ve created a checklist below of the most deductions you can claim for your small business. As always, check with your accountant or tax preparer if you have any questions or need clarification. Note that some of the expenses listed below will need to be “depreciated” or expensed over several years. Speak to your tax preparer for more information.


Rent, Mortgage, and Utility Tax Deductions

These tax deductions include costs associated with renting a building for business, using part of your home as an office, utility bills, and other factors.
