Does a write-off mean something is free?
No. A write-off reduces your taxable income, so you only save a portion of the cost equal to your tax rate, not the entire amount.

What Is a Tax Write-Off?
A tax write-off is a deductible expense that reduces the income you are taxed on, which lowers your tax bill but does not make the purchase free.
Write-off is just an everyday word for a tax deduction. When you write off a business expense, you subtract it from your income so you are taxed on a smaller amount. For example, if you spend money on a deductible expense, it reduces your taxable income, and your tax savings equal that amount multiplied by your tax rate, not the full cost.
A common myth is that writing something off means you get it for free or get the money back dollar for dollar. In reality, a deduction only saves you a fraction of the cost. To be deductible, a business expense generally must be ordinary and necessary for your line of work, and you need records to back it up.
Deductions are different from tax credits. A deduction lowers the income you pay tax on, while a credit lowers your actual tax dollar for dollar. Knowing the difference helps set realistic expectations about what a write-off does.
