Your Business/Side Hustle Tax Deduction Checklist

Almost 50% of people under the age of 45 have a side hustle.

And here's some shocking news for some of you...

That means you are a "business owner".

But the problem is a lot of people don't think of themselves that way and forget to write off expenses on their taxes.

Now, don't be like that Seinfeld clip and just think because you "write something off" means you don't have to pay for it.

But it will lessen your tax burden. So make sure you go down this list and add it up to save yourself some money from Uncle Sam!

Advertising, marketing, and promotion costs

Costs associated with marketing, advertising, and otherwise promoting your business are all tax-deductible. This includes the following expenses:

  • Website hosting and domain
  • Website design, themes, plugins, stock photos, fonts, and other related costs

  • Professional consultation fees, including working with lawyers, accountants, and business consultants, can all be deducted.

Bad debt

Unfortunately in the business world, sometimes clients don’t pay invoices or pay back their loans. This creates "bad debt". 

But there is a small upside to those disasters. If these debts can be directly tied to a business expense, these expenses can be used as deductions.


Contributions to a 501(c)(3) non-profit can be used as a tax deduction.

Just be sure to get a donation receipt from said organization.

Continuing education
