Do I need to collect sales tax on what I sell?
It depends on what you sell and where your customers are. Sales tax is a state and local matter, and rules vary widely. Generally, tangible goods are taxable and many professional services are not — b…Read more
Can I hire my own kids in my business to save on taxes?
Yes, and it can be legitimately tax-smart if done correctly. When you pay your children for real work in your business, those wages are a deductible business expense, and the child can earn up to the…Read more
How much of my phone, internet, and software can I deduct?
You deduct the business-use percentage, not the whole bill, for mixed personal-and-business items. For a cell phone you use 60% for work, deduct 60% of the bill; same logic for home internet. Software…Read more
What is the Augusta rule, and can I rent my home to my own business?
The Augusta rule (Section 280A) lets you rent your personal residence to your business for up to 14 days a year and receive that rent completely tax-free, while the business deducts it as an expense.…Read more
What is an accountable plan and why would my S-corp need one?
An accountable plan is a formal arrangement that lets your business reimburse you (or employees) for business expenses you paid personally — like a home office, mileage, or supplies — without that rei…Read more
What records do I need to keep for the IRS as a self-employed person?
Keep enough to prove both your income and every deduction. That means receipts and invoices, bank and credit-card statements for business accounts, a mileage log, records of asset purchases (for depre…Read more
What is the estimated-tax safe harbor and how does it protect a self-employed person?
The safe harbor is a set of payment levels that protect you from underpayment penalties even if you end up owing more at filing. You're generally safe if your quarterly estimated payments total at lea…Read more
What payroll requirements come with running an S-corp?
Once you elect S-corp treatment and take a reasonable salary, you become an employer with real obligations — even as a one-person business. You must run formal payroll: withhold federal income tax, So…Read more
What is the self-employment tax deduction for half of the tax?
When you're self-employed you pay both the employee and employer halves of Social Security and Medicare — about 15.3% — through self-employment tax. To partly offset that, the IRS lets you deduct half…Read more
Should I incorporate my business or stay a sole proprietor?
For most solo service providers, the more useful first move is forming an LLC rather than incorporating, because an LLC delivers liability protection with far less complexity than a corporation. Stay…Read more
What's the tax difference between an LLC taxed as a sole proprietor and one taxed as an S-corp?
The legal entity is identical — the difference is purely how profit is taxed. An LLC taxed as a sole proprietorship (the default for a single owner) reports all profit on Schedule C, and the entire ne…Read more
How do I deduct business travel correctly?
Travel away from your tax home overnight for business is deductible, and the rules are generous if you follow them. You can deduct airfare, lodging, 50% of meals, rental cars, taxis, baggage, and othe…Read more
What's the difference between depreciating an asset and expensing it?
Expensing means deducting the full cost in the year you buy something; depreciating means spreading the deduction across the asset's useful life. By default, the tax code makes you depreciate larger,…Read more
When should I hire a bookkeeper or CPA instead of doing it myself?
Doing your own books is fine when you're a low-volume sole proprietor with simple income and a handful of expenses — software plus a dedicated business account may be enough. Consider a bookkeeper onc…Read more
What percentage of my income should I set aside for taxes as a freelancer?
A common starting rule is to set aside 25–30% of your net self-employment income for federal taxes, bumping toward 35–40% if you're in a higher bracket or a high-tax state. The figure is higher than m…Read more
How do taxes work if I have both a W-2 job and 1099 side income?
You combine them on one return, but they're taxed differently along the way. Your W-2 job has income, Social Security, and Medicare taxes withheld automatically. Your 1099 side income has nothing with…Read more
Do I have to issue 1099s to people my business pays?
Often, yes. If your business pays an unincorporated contractor, freelancer, or service provider $600 or more in a year for business services, you generally must issue them a Form 1099-NEC by January 3…Read more
I'm just starting out self-employed — what tax setup should I get right first?
Get a few foundations in place and the rest gets much easier. First, open a dedicated business bank account and card so personal and business money never mix — this protects deductions and any liabili…Read more
How do Solo 401(k) contributions work — the employee plus employer math?
A Solo 401(k) lets you wear two hats: employee and employer. As the employee you can defer up to $23,500 in 2025 ($31,000 if you're 50+ with the $7,500 catch-up). As the employer you can add a profit-…Read more
Should I use a Solo 401(k) or a SEP-IRA?
For most one-person businesses with no employees, the Solo 401(k) wins because it adds an employee deferral on top of the employer contribution. A SEP-IRA only allows the employer piece — up to about…Read more
What is a SIMPLE IRA and when does it make sense for a small business?
A SIMPLE IRA (Savings Incentive Match Plan for Employees) is a retirement plan built for businesses with 100 or fewer employees that want something easier than a 401(k). In 2025 employees can defer up…Read more
Can a high-earning solo use a defined-benefit or cash-balance plan to save more?
Yes, and it's one of the most powerful tools for a high-income solo who wants to shelter far more than a Solo 401(k) allows. A defined-benefit or cash-balance pension plan can permit contributions wel…Read more
Can I add a Roth option to my Solo 401(k)?
Yes — most Solo 401(k) providers now offer a Roth bucket for the employee deferral. You can put up to the full $23,500 employee portion in 2025 ($31,000 if 50+) into Roth, where it grows tax-free and…Read more
Can my spouse contribute to my Solo 401(k)?
Yes, if your spouse genuinely works in the business and is paid for it, they can participate in the same Solo 401(k) — this is one of the plan's hidden advantages. A spouse who earns compensation from…Read more
