As a freelancer, there are a number of costs you need to consider for yourself:
Meal costs | As a freelancer, you are responsible for your own meal. Sometimes it happens that the client provides a meal (for a fee).
Travel costs | Keep in mind that travel costs are included in the hourly rate. These costs are not reimbursed. However, the IRS does have travel expense regulations on travel expenses if you meet the conditions. For example, do you drive your own car on business trips? Then you can deduct 0.21 cents (rate 2023) per business mile from your turnover. Read more about that in this article.
Parking costs | You may have to pay for parking at a client's location. In that case, the parking costs of your car are for you. These costs are also included in the hourly rate. Note: parking costs are not tax-deductible, unless you drive a company car. This is because you can already deduct a certain amount per mile.
