Should my construction business be an LLC or S-corp?
Here’s what most people miss: an LLC can elect to be taxed as an S-corp. You don’t have to choose one or the other. Most construction business owners start with an LLC for liability protection, then later elect S-corp taxation when it makes financial sense.
The real question is when to make that election. It comes down to profit level. As a sole proprietor or standard LLC, you pay self-employment tax on all your net profit. That’s 15.3% on top of income tax. With S-corp taxation, you pay yourself a reasonable salary and take the remaining profit as distributions. Those distributions avoid self-employment tax entirely.
The math usually works in your favor once you’re clearing around $40,000 to $60,000 in annual net profit. Below that threshold, the tax savings don’t cover the added costs of running payroll and filing an S-corp return. Above it, the savings can be significant. Our Nampa tax professionals run these calculations regularly for clients trying to decide.
Construction businesses tend to hit that profit threshold faster than many industries, but the income is also more variable. A contractor making $80,000 one year might make $35,000 the next if projects slow down. The S-corp election still makes sense in most cases, but you need to set a reasonable salary that works across good years and lean years.
The added requirements matter. S-corp taxation means you must run payroll for yourself, pay quarterly payroll taxes, and file both a personal and business tax return. If you have employees already, the marginal cost of adding yourself to payroll is lower. If you’re a one-person operation, you’re adding complexity that wasn’t there before.
The IRS watches “reasonable salary” closely, especially in construction where labor is the business. Paying yourself $20,000 when you’re billing out at $100 an hour raises red flags. Your salary should reflect what you’d pay someone else to do your job.
Starting out, an LLC taxed as a sole proprietorship or partnership is simpler and cheaper. Once profits consistently exceed that $40,000 to $60,000 range, talk to someone who can run the numbers for your specific situation. The right choice depends on your actual profit, not general rules of thumb.
