1-800Accountant has released a new data-driven report, The Small Business Deduction Index, offering insights into how tax deduction trends evolve as businesses increase revenue. The report analyzes aggregated and anonymized tax data from the company’s client base to benchmark deduction behaviors among sole proprietors, LLC owners, freelancers, and independent contractors.
The study segments businesses into four revenue categories ranging from pre-revenue startups to companies generating more than $100,000 annually. It tracks both the percentage of business owners claiming deductions and the average deduction amount across key expense categories.
The findings show that while deductions generally increase alongside revenue growth, the rate of increase differs significantly depending on the expense category.
Advertising emerged as the fastest-scaling deduction category, with average claims rising from $1,303 among businesses earning up to $25,000 annually to $14,684 for businesses exceeding $100,000 in revenue. Supply-related deductions also showed substantial growth, increasing from $2,912 to $24,109 across the same revenue tiers.

Vehicle mileage deductions demonstrated more gradual but consistent growth, while home office deductions remained relatively stable regardless of revenue size, both in claim frequency and average deduction value.
“This data tells a story that most small business owners haven’t been able to access before,” said Gary Milkwick, CFO at 1-800Accountant. “When you can see what businesses at your revenue level actually claim, you stop guessing and start making informed decisions. The gap between under-claiming and accurate claiming is often measured in thousands of dollars.”
The report also identifies several tax deduction categories where smaller businesses may be missing potential savings due to poor recordkeeping rather than ineligibility. Business meals, liability insurance, and travel expenses were among the most commonly underclaimed deductions despite qualifying under existing IRS guidelines.
According to the report, only 33% of businesses claimed meal-related deductions, while liability insurance deductions were reported by just 22% of respondents. Travel deductions were claimed by 23% of businesses overall, though that figure increased significantly among higher-revenue businesses.
The analysis additionally highlights unique deduction patterns among pre-revenue businesses, where marketing and repair expenses tend to be front-loaded while vehicle mileage claims remain comparatively lower due to limited customer-facing activity during the early growth phase.
With the release of The Small Business Deduction Index, 1-800Accountant aims to provide small business owners with clearer benchmarks to better understand industry deduction trends and improve tax planning strategies.
