You can absolutely file your own business taxes. There’s no legal requirement to use a CPA. Tax software like TurboTax and FreeTaxUSA walks you through the forms, and plenty of business owners go that route. The real question is whether doing it yourself is actually saving you money or costing you more than a CPA would charge.

For a simple sole proprietorship with a handful of expenses, self-filing is manageable. But most contractors, plumbers, electricians, and other trades businesses aren’t that simple. You’re dealing with equipment depreciation, vehicle deductions, material costs, subcontractor payments, potential home office deductions, and the qualified business income deduction under Section 199A. Each of these has specific rules, and getting them wrong means either overpaying or triggering an audit.

The biggest issue isn’t the filing itself. It’s the deductions you don’t know to take. A CPA who works with trades businesses knows what to look for. They know the difference between Section 179 expensing and bonus depreciation on that new truck. They know how to handle the 1099s you issued to subs and whether your entity structure is costing you extra in self-employment tax. Tax software only asks questions. It doesn’t tell you what you’re missing.

Then there’s the books themselves. If your financial records are a mess going into tax season, filing your own return means building on a shaky foundation. You’re guessing at numbers, forgetting expenses, and hoping it’s close enough. Having contractor bookkeeping services in place throughout the year means your CPA has clean data to work with, and that’s where the real tax savings come from. You can’t deduct what you didn’t track.

The math usually works in favor of hiring a professional. A CPA might charge $1,200 to $2,000 for a business tax return. If they find $5,000 or $10,000 in deductions you would have missed, the fee pays for itself several times over. And if something goes wrong with the IRS, you have someone in your corner who understands the return and can respond on your behalf.

If you’re a sole proprietor with minimal expenses and you’re confident in your records, filing yourself is fine. But if you’re running crews, buying equipment, paying subcontractors, or growing your business, a CPA who understands your industry is worth every dollar. The goal isn’t just to file a return. It’s to pay only what you actually owe.
