A 2021 Tax Guide for First Time Small Business Owners


By Michelle Loredo

We are officially in 2021! The tax season is here, and things are looking a bit different. For example, if you have received economic relief from the Small Business Administration, earned income can be taxable.

If you’re filing taxes as a first-time small business owner, don’t worry! We have you covered. We have put together a small business tax guide overview that gives you tips and resources for the 2021 tax season.

Change to the Tax Code and COVID-19

The last major piece of legislation that changed the tax code occurred back in 2017. The Tax Cuts and Jobs Act of 2017 lowered taxes for corporations and offered new tax breaks. There was an update to the Act in 2019 that adjusted standard deductions to inflation, the Affordable Care Act “individual mandate” fee was dropped, and changes to itemized deductions.  

Have you received monetary assistance from the Small Business Administration? If you have received aid, you still need to report your taxes to the Internal Revenue Service. If you received help from the Paycheck Protection Plan in 2020, unforgiven funds are taxable. 

If your business qualifies for the Employee Retention Tax Credit, you are eligible for a tax credit. The tax credit is equal to 50 percent of your qualifying employee wages if they were part of your business from March 13, 2020, through January 1, 2021.

Lastly, if you provided COVID-19-positive employees sick leave in 2020, you could qualify for a tax credit under the Families First Coronavirus Response Act. If you do, you are eligible for a 100 percent tax credit that matches healthcare expenses. 

For a complete inside look at changes to the tax code, meet with a Certified Public Accountant to find out all the applicable updates.
