How Cost Studies Can Save You Money on Your Tax Return

If your business makes, handles, or sells physical products, your cost of goods sold (COGS) is one of the most powerful tools you have for reducing taxable income. Because costs of sales directly offset your revenue, what you can legitimately include in that line item matters. And most businesses are leaving money on the table.

Typically, expenses like rent, utilities, and non-direct labor cannot be included in COGS. Unless you’re using proper cost accounting. Here’s how it works.

What Is Section 471 and Why Should You Care?

Section 471 is a little-known tax code section with a big impact on product-based businesses. It was originally written to describe how manufacturers can properly allocate a portion of their operating costs, like fixed overhead, to the cost of sales.

Some legwork is required, though. To take advantage of it, your business needs to:

  • Keep books and records under Generally Accepted Accounting Principles (GAAP)
  • Use accrual accounting rather than cash basis
  • Document your cost allocations properly

We recommend working with your accountant to get those foundations in place. Once your business follows these accounting methodologies, expenses typically treated as pure operating costs, like rent, may be partially allocated to cost of sales through accurate inventory costing.

What Is a Cost Study?

A cost study is the documentation that makes your allocations defensible. It’s a cornerstone of strategic tax planning for any business that carries inventory.

One method we recommend: track your employees’ time for 90+ days to get a reliable average of where their hours actually go. This is especially valuable for retail and production businesses where wages are split between selling and getting products ready for sale.

A Real-World Example

Say your team spends a third of their time assembling, packaging, labeling, and prepping products for sale. A well-documented cost study could allow you to allocate a portion of cost of sales to wages, payroll taxes, employee benefits expenses, and more… meaning lower tax liability backed by documentation. 

Don’t Try This at Home

These strategies only work when they’re employed alongside the required accounting regulations. In other words, we strongly recommend working with small business accountants who have experience with:

  • Cost allocation
  • GAAP accounting
  • Accrual basis financial statements
  • Small business tax planning

Getting this wrong can create more problems than it solves. Getting it right can meaningfully change what you owe.
