可抵扣费用的基本原则
要使费用可以抵扣，必须是"经营业务所必需的正常支出"。具体来说，必须满足以下三个条件：
- Business Relevance - The expense is directly related to business activities
- Necessity - The expense is necessary for conducting business
- Reasonableness - The amount is reasonable by social standards
重要：保存收据
要申报费用，必须保存收据。符合电子帐簿保存法的数字存储也是可以接受的。保存期限一般为7年。
