Tax deduction

Last Updated January 17, 2024

A tax deduction, also known as a “tax write-off,” refers to an eligible expense that can be subtracted from your taxable income. By deducting the expense amount from your taxable income, you effectively reduce the amount on which you are required to pay taxes. However, the expense must meet the Internal Revenue Service (IRS) criteria for a tax deduction.

Here is a comprehensive list of deductions commonly available to self-employed businesses organized as sole proprietorships or partnerships. Some are directly related to business operations, while others are personal deductions that small business owners should be mindful of.

Tax Deduction Benefits

Optimizing your available tax deductions can lead to substantial savings, potentially reducing your tax bill by hundreds or even thousands of dollars. Consider the following example:

Let’s take Joe, a self-employed writer with $60,000 in self-employment income in 2023. Joe is subject to a 15.3% self-employment tax and income tax based on his tax rate. Initially, his tax liability was $13,343.

In early 2023, Joe joined Bench, a bookkeeping service, which identified $6,000 in contractor expenses he was unaware of. These expenses qualify as tax deductions, reducing Joe’s net self-employment income to $54,000.

With $54,000 in taxable self-employment income, Joe’s revised tax liability is $11,830. The additional business expenses saved Joe over $1,500 in taxes. By identifying and leveraging multiple deductions, small business owners like Joe can significantly reduce their taxable income, leading to substantial savings.

Staying Informed on Deductions

For small business owners, staying informed about relevant deductions can be challenging. Many individuals struggle to track deductions throughout the year, often attempting to piece together information at year-end, which can result in missed opportunities for tax write-offs.

This is where effective bookkeeping becomes crucial. To claim deductions successfully, accurate record-keeping and monthly bookkeeping updates are essential. Bench, a bookkeeping service, provides a solution by ensuring that deductions are identified and recorded each month, minimizing tax liability. This proactive approach allows business owners to confidently submit accurate information to their accountants or entrust Bench with both bookkeeping and tax filing responsibilities for a seamless and stress-free tax season.
