小企业税务扣除清单：你应该知道的30多项抵扣
为什么税务扣除很重要
Business tax deductions reduce your taxable income, which directly lowers your tax bill. Every dollar of legitimate business expense you deduct is a dollar that isn't taxed. For a business in the 21% corporate tax bracket or an individual in the 24% bracket, a $1,000 deduction saves $210-240 in taxes. Keeping good records throughout the year and knowing what's deductible ensures you don't overpay.
企业税务抵扣可减少您的应税收入，从而直接降低您的税单。每抵扣一美元的合法业务支出，这一美元就无需缴税。对于适用21%公司税税率的企业或24%税率的个人，1,000美元的抵扣可节省210-240美元的税款。全年保持良好的记录并了解哪些支出可以抵扣，确保您不会多缴税款。
家庭办公室扣除
If you use part of your home exclusively and regularly for business, you can deduct a portion of your rent/mortgage, utilities, insurance, and maintenance. Use the simplified method ($5 per square foot, up to 300 sq ft = $1,500 max) or the regular method (actual expenses based on the percentage of your home used for business). The space must be used exclusively for business — a kitchen table doesn't qualify, but a dedicated home office room does.
如果您将家中一部分空间专门且定期用于业务，您可以抵扣部分租金/房贷、水电费、保险费和维修费。使用简化方法（每平方英尺5美元，最高300平方英尺=最高1,500美元）或常规方法（按家中用于业务的比例计算实际费用）。该空间必须专门用于业务——厨房餐桌不符合条件，但专用的家庭办公室房间符合。
车辆和差旅费用
Business use of your vehicle is deductible using either the standard mileage rate (varies yearly) or actual expenses (gas, maintenance, insurance, depreciation). Keep a mileage log with dates, destinations, and business purpose. Business travel — flights, hotels, 50% of meals, conference fees — is deductible when the primary purpose is business. Commuting from home to your regular workplace is not deductible, but travel to client sites and between work locations is.
您的车辆用于业务的部分可以抵扣，使用标准里程费率（每年变动）或实际费用（油费、保养、保险、折旧）。保留里程日志，记录日期、目的地和业务目的。商务旅行——航班、酒店、50%餐饮费、会议费——在主要目的为业务时可以抵扣。从家到常规工作地点的通勤不可抵扣，但前往客户地点和工作地点之间的出行可以抵扣。
设备、用品和技术
Section 179 allows you to deduct the full cost of qualifying equipment and software in the year of purchase (up to annual limits) rather than depreciating over years. This includes computers, furniture, machinery, vehicles, and off-the-shelf software. Ordinary supplies, shipping costs, professional books and publications, and business-related software subscriptions are also fully deductible. Cloud services, website hosting, and domain fees count too.
第179条允许您在购买当年（最高达年度限额）抵扣符合条件设备和软件的全部成本，而不是分多年折旧。这包括计算机、家具、机械、车辆和现成软件。普通办公用品、运费、专业书籍和出版物以及与业务相关的软件订阅费也可全额抵扣。云服务、网站托管和域名费用同样适用。
专业服务和保险
Fees paid to accountants, lawyers, consultants, and other professionals for business purposes are fully deductible. Business insurance premiums — general liability, professional liability/E&O, workers' compensation, commercial property, and business interruption insurance — are deductible. Health insurance premiums for self-employed individuals and their families are also deductible as an above-the-line adjustment to income. Retirement plan contributions (SEP IRA, Solo 401k) can provide significant deductions while building your future.
为业务目的支付给会计师、律师、顾问和其他专业人士的费用可全额抵扣。商业保险保费——一般责任险、职业责任险/E&O、工伤赔偿险、商业财产险和业务中断险——均可抵扣。自雇人士及其家人的健康保险保费也可作为线上调整项目抵扣。退休计划缴费（SEP IRA、Solo 401k）可在为未来积累的同时提供可观的税务抵扣。
