Also, uniquely in the USA, interest payments on debt can be deducted from your income. There are some caveats to deducting this from personal taxes rather than business taxes, but in general if you can show your personally used the loan for business purposes, you can use the Schedule C form to deduct the interest on it from your personal income to lower taxes paid.
Deduction of interest against revenue isn't allowed in other countries for business purposes?
I know the home mortgage deduction might be somewhat unique, but interest costs seem a business expense pretty clearly.
