Regarding the following, please be aware that Bonsai does not provide tax advice. We always recommend talking to a licensed accountant or other tax professional.
Tracking driving with expenses
At this time, you cannot track mileage on Bonsai. Instead, we encourage users to track driving-related expenses inside of Bonsai. These can things such as gas expenses, car repairs and more.
The primary complication with this expense-tracking approach for tax-deduction purposes is that you must alter the tax deductions you are taking for each. Your tax deduction for each driving-related expense must be the percentage you typically use your car for business purposes. In other words, if you have a $50 gas expense and use your car 50% of the time for work, then you can deduct $25.
Within Bonsai, this means you may have to manually adjust your driving related tax deductions so it reflects this percentage amount.
