When considering whether an expense is deductible or not, you may want this rule of thumb in mind: The Internal Revenue Service (IRS) guideline for freelancer tax deductions is that expenses must be ordinary and necessary.
One of the most common deductions for freelancers, in order to claim a home office on your taxes, the designated space must be used regularly and exclusively for business operations and must be the principal location where business is conducted.
The materials you purchase to work in your home office, such as paper, pens, pencils, pads, printer ink, staples, paper clips, etc, can typically be deducted at full cost as long as the items are used for business.
If you require specific hardware, such as a laptop, personal computer, tablet, or other types of equipment to run your business, these purchases may count as deductions.
If you have a website and pay fees for web hosting, these expenses can likely be deducted from your taxes. If you use other online tools for your business, fees you pay for these services can also usually be deducted.
