It’s not bad to write something off—quite the opposite! In fact, the IRS provides thorough instructions to help small businesses write off as many qualifying expenses as possible. In general, and with an accountant’s guidance, you can and should write off as many expenses you can. Of course, it’s obviously bad (read: illegal) to falsify a business expense or inflate the cost of a qualifying expense. If you do this, you could be audited, and you’ll be subject to fines and other penalties from the IRS. Don’t do it! Additionally, adjusting your business' taxable income may change which loan amounts you qualify for. Again (we really can't stress this enough), make sure to talk to a CPA, tax advisor, or small-business banker to discuss your specific situation.
