How Does a Tax Write-Off Work?

Definition

In business, when a person buys equipment needed for work or has travel costs, the expenses can be counted as tax write-offs. Write-offs are deductions from the amount of taxable income that a person has earned.

Possible Write-Offs

Some items that are considered tax write-offs are computers, office supplies, work attire, office furniture, training and reference materials. Transportation mileage can also be considered a tax write-off.

How to Claim

To claim these write-offs while filing taxes, you have to have proof of the item or millage. This is often done by keeping receipts and keeping a log of millage. Some people have credit cards that they use only for business transactions. When it is time to do their taxes, these individuals use the credit card summary as proof of write-off purchases. The person will then add up the expenses and deduct this number from the amount of money earned for the year.

Advantages

Tax write-offs reduce the amount of income you must claim on your tax return, which indirectly reduces the amount of taxes you have to pay. Having a lower income lowers the amount of taxes a person has to pay in a year.
