When you manage a single‑person enterprise, every dollar you take in doubles as your tax. Thankfully, the tax code is packed with options to ease that burden, given you plan ahead and meet deadlines. Below is a practical guide to proven methods that can help you save more of your hard‑earned money.
- Select the Appropriate Business Structure
Your legal form determines how you’re taxed. Sole proprietorships are simple but expose personal assets to liability. If you’re comfortable with extra paperwork, consider forming an LLC or an S‑Corporation.
- LLC: Gives liability protection and flexible profit‑sharing. Income is passed through to your personal return, preventing double taxation.
- S‑Corporation: Permits you to pay yourself a reasonable salary (subject to payroll taxes) and take the remaining profits as dividends, possibly saving on self‑employment tax.
- Maximize Deductions Early
The sooner you identify deductible expenses, the more you can reduce taxable income. Common deductions for solo entrepreneurs include:
- Home office costs (a share of rent, utilities, insurance, and internet).
- Vehicle mileage or real vehicle expenses if you use a car for business.
- Professional services such as legal, accounting, consulting fees.
- Health insurance premiums paid directly by the firm.
- Retirement contributions (IRA, Solo 401(k), SEP‑IRA).
Keep detailed records—digital receipts,
確定申告 節税方法 問い合わせ mileage logs, and a dedicated expense spreadsheet—so you can support every deduction if the IRS asks.
- Leverage the Qualified Business Income Deduction
Under Section 199A, many small businesses can claim up to a 20% deduction on qualified business income. The deduction phases out for higher‑income taxpayers, yet it can still reduce a sizable chunk of your liability if your earnings are within the threshold.
- Defer Income, Accelerate Expenses
Tax timing is an underrated strategy. If you expect to be in a lower tax bracket next year—perhaps because you anticipate a dip in business activity—consider deferring invoicing until January. In contrast, acquire necessary equipment or pay for software subscriptions in December to claim the full deduction this year.
- Apply Depreciation and Section 179
Large purchases like computers, office furniture, or a new machine can be written off over several years via depreciation. Section 179 lets you write off the full cost of qualifying equipment in the year it’s placed in service, up to a limit that changes annually. This can create a huge instant tax benefit.
- Take Care of Payroll Taxes
If you operate as an S‑Corp, you must pay yourself a "reasonable salary." The IRS scrutinizes this closely; a salary that's too low can trigger penalties. After you establish a defensible salary, the remaining profits are taxed only once, at the corporate level, and then at your personal rate on dividends, which are exempt from self‑employment tax.
- Boost Retirement Contributions
Solo retirement plans such as a SEP‑IRA or Solo 401(k) allow you to contribute up to 25% of your net earnings—often exceeding the limits on a traditional IRA. Contributions are tax‑deferred, and you can even get a tax deduction for the contributions.
- Take Advantage of Health Savings Accounts (HSAs)
If you have a high‑deductible health plan, an HSA provides triple tax advantages: contributions are tax‑deductible, growth is tax‑free, and withdrawals for qualified medical expenses are tax‑free. The contribution limits are generous and can be a powerful way to lower taxable income.
- Keep Up with State and Local Rules
Many states offer small‑business tax credits, research and development incentives, or low‑income tax rates for sole proprietors. Consult your state’s department of revenue website or a local tax professional to make sure you’re not missing a credit.
- Plan for Estimated Taxes
Solo businesses often pay taxes quarterly via estimated tax payments. Failing to pay enough can trigger penalties. Employ the IRS’s "Safe Harbor" rule: pay at least 90% of the current year’s tax or 100% of the previous year’s tax (110% if your income exceeded $150,000).
- Examine a Tax‑Efficient Business Expense Strategy
Certain expenses are more tax‑efficient when treated as capital expenditures rather than current expenses. For example, buying a computer can be capitalized and depreciated, while buying office supplies remains a current expense. Being aware of these nuances can influence when and how you record costs.
- Keep an Eye on Emerging Tax Laws
Tax laws evolve. For example, recent proposals to alter the deduction for business interest or tweak the thresholds for the Qualified Business Income deduction could influence your strategy. Stay updated through reputable news sites, IRS updates, or by keeping a relationship with a tax advisor.
- Work With a Qualified Tax Professional
While DIY software can take care of basic filings, a seasoned CPA or tax attorney can uncover deductions you might miss, advise on legal structures, and help you navigate complex areas such as payroll and retirement plans. The cost of professional advice is often outweighed by the tax savings they secure.
- Document Your Reasoning
During an audit, having a clear, logical rationale for your deductions, business structure, and income deferrals simplifies the process. Keep a "tax strategy" file that explains your decisions, backed by receipts, contracts, and correspondence.
- Reassess Annually
Tax planning isn’t a one‑time task. Each year, evaluate your income, expenses, and business goals. Alter your structure, contributions, and deduction strategy accordingly to keep your tax liability as low as possible.
By combining these approaches—structuring your company wisely, maximizing deductions, timing income and expenses, and staying current with tax law—you can dramatically cut the tax burden on a one‑person company. The key is disciplined record‑keeping, proactive planning and periodic consultation with a tax professional. The money you save can be reinvested in your business, used for personal enjoyment, or saved for future goals.
