Siding Installation Business: S-Corp vs. Sole Proprietorship Tax Comparison
Siding installation is an exterior trade that shares characteristics with roofing and painting. The work isn’t a specified service trade or business (SSTB) under IRC 199A, so the full 20% QBI deduction applies. Materials (vinyl, fiber cement, wood, stone veneer) represent 35-45% of revenue. The equipment needs are modest (saws, nail guns, scaffolding, ladders, brake for metal trim), keeping the startup capital requirement low. Workers’ comp rates are moderate to high (7-12%) because the work involves heights and power tools.

What does a siding installer’s tax picture look like?
What happens to my business if I die without a succession plan?
Without a succession plan, your business’s fate depends on its legal structure. A sole proprietorship has no legal existence apart from you and simply ceases to exist. A single-member LLC’s operating agreement may or may not grant transfer rights to your estate. If it is silent, state default rules apply, and most states allow the interest to pass but not management rights, leaving the estate with an economic interest it cannot control. An S-Corp’s shares pass through the estate, but if the heir is an ineligible S-Corp shareholder (a nonresident alien, for example), the election terminates retroactively. A buy-sell agreement funded by life insurance is the standard solution: the policy pays out at death, and the agreement dictates who buys the interest and at what price.
