Tax Benefits of Modular Building for Small Businesses

June 3, 2025 - 6 minutes read

As a small business owner, you’re always looking for ways to grow your operations while managing costs effectively. One key opportunity many entrepreneurs overlook is the potential tax benefits offered by modular building solutions. Specifically, Section 179 of the IRS tax code can make investing in modular construction a financially-savvy choice.

This blog will break down the tax advantages of modular buildings, how Section 179 can help your business, and why modular construction might just be the perfect fit for small businesses in need of cost-effective, flexible spaces.

What Is Modular Building?

First, if you’re unfamiliar with modular building, here’s a quick rundown. Modular construction involves creating pre-fabricated sections of a structure (modules) in an off-site manufacturing facility. These modules are then transported and assembled on-site.

Modular construction offers several benefits, including faster build times, lower costs, high-quality craftsmanship, and flexibility for future expansion. But what makes modular buildings particularly appealing for small businesses is their tax advantages.

Understanding Section 179 of the IRS Code

Section 179 of the IRS tax code is a game-changer for small businesses. It allows companies to deduct the full purchase price of qualifying equipment and property, including certain modular buildings, in the year they are acquired and put into use.

Traditional depreciation schedules require business owners to stretch deductions over several years, but Section 179 accelerates this process. The result? Significant upfront tax savings that can help businesses reinvest in growth areas like hiring, marketing, or new equipment.

How Does It Work?

For tax year 2025, small business owners can deduct up to $1.17 million in qualifying expenses under Section 179 (subject to changes from the IRS). This amount includes modular buildings if they are used for your business operations.

Here’s how it works step by step:

  1. Purchase or lease a modular building for your business before the end of the tax year.
  2. Ensure the building is installed and ready for use before December 31.
  3. Deduct the entire purchase price (up to the annual limit) when filing your tax return.

Since the deduction covers the first year, businesses see immediate tax relief, making it easier to manage cash flow and offset upfront costs.

Why Modular Buildings Qualify Under Section 179

Section 179 applies to tangible personal property and certain improvements to non-residential property. Modular buildings often fall under this category because they are pre-fabricated structures designed to serve as office spaces, retail locations, or production areas.

Common modular building uses for small businesses include:

  • Office Space: For growing teams that need a low-cost alternative to traditional buildings.
  • Retail Shops: Perfect for pop-up stores or seasonal businesses.
  • Workshops & Studios: Flexible spaces for creative entrepreneurs like photographers, designers, or makers.
  • Storage Facilities: A practical solution for managing inventory and materials.

The modular nature means your building can adapt and grow with your business, all while offering excellent tax-saving potential.

How Modular Buildings Save You Beyond Section 179

While Section 179 offers significant financial benefits, modular construction can help save more in several ways:

  • Faster Build Times: Modular buildings are constructed off-site, meaning less downtime and quicker access to a functional space. Accelerated project timelines mean you can start generating revenue sooner.
  • Lower Material Waste: Modular building practices reduce construction waste, saving money on materials while being eco-friendly.
  • Reduced Labor Costs: Off-site assembly streamlines labor needs, lowering overall costs.

Together, these features make the financial case for modular buildings even stronger when paired with Section 179 deductions.

Tips for Maximizing Your Modular Building Investment

If you’re planning to take advantage of Section 179 benefits, keep these tips in mind:

  1. Consult Your Tax Professional: Ensure your modular building purchase qualifies under Section 179 guidelines and understand any recent IRS updates.
  2. Plan Ahead: Purchase and install your modular building before December 31 to qualify for deductions within the current tax year.
  3. Choose a Trusted Provider: Work with a modular building provider that understands the needs of small businesses. They can guide you through the process and ensure everything is ready on time.

The Bottom Line

Modular buildings are more than just a construction trend. They are a strategic investment for small business owners looking to expand efficiently while optimizing their tax savings. Through Section 179, you can deduct the cost of your modular building upfront, giving you the cash flow and flexibility to focus on growing your business.
