busy Small Business Owner Missing Tax deductions

While you're busy serving customers and growing your business, it's easy to overlook valuable deductions that could significantly reduce your tax burden.


Research shows that 90% of small business owners miss important tax deductions, particularly the home office deduction, which could save thousands annually. With Iowa's recent flat tax rate of 3.8% (down from 5.7% in 2024), every deduction counts more than ever.


Section 179 Equipment Deductions: Iowa's Catch-Up Story

Many Iowa business owners don't realize that Iowa finally coupled with federal Section 179 limits starting in 2020, but the journey to that point left confusion in its wake.


2025 Federal Limits:

  • Section 179 deduction: Up to $1.25 million

  • Phase-out threshold: $3.13 million



Iowa's Alignment: Starting in 2020, Iowa matched federal limits, but many business owners still think we're stuck with the old $25,000 limit. Iowa tax law changes from 2018. If you purchased equipment in recent years and didn't take the full deduction because you thought Iowa had lower limits, you could file an amended return.


Example: A Des Moines contractor who bought a $180,000 excavator in 2021 initially only deducted $25,000 on their Iowa return because they weren't aware of the law change. After filing an amended return, they saved over $11,000 in Iowa taxes.


Home Office Deduction: More Flexible Than You Think

Many Iowa small business owners work from home at least part-time, but few claim this valuable deduction. For 2025, you have two options:


Simplified Method:

  • $5 per square foot (up to 300 sq ft)

  • Maximum deduction: $1,500

  • No record-keeping of actual expenses


Actual Expense Method:

  • Deduct a percentage of home expenses based on office size

  • Includes utilities, mortgage interest, property taxes, and insurance

  • Often results in larger deductions for bigger spaces


Iowa Consideration: Remember that Iowa allows home office deductions when taken on federal returns, making this a double win for Iowa business owners. Iowa is among the states that allow unreimbursed employee expense deductions.


Professional Development and Education

Iowa businesses often miss deductions for:

  • Industry conferences and workshops (including virtual events)

  • Professional certifications and license renewals

  • Books, magazines, and online courses related to your business

  • Software subscriptions for professional development


Local Example: A Cedar Rapids marketing consultant deducted $3,200 for attending a digital marketing conference in Chicago, including travel, lodging, and registration fees.


Vehicle Expenses: Choose Your Method Wisely

  1. Standard Mileage Method: Track business miles and multiply by $0.67

  2. Actual Expense Method: Deduct actual costs (gas, repairs, insurance, depreciation)


Iowa-Specific Tip: Keep a detailed mileage log if you travel frequently between Iowa cities for business. Many Iowa business owners use the simplified method without realizing the actual expense method could save them more, especially with higher fuel costs.


Top Mileage Tracking Apps: If you're still using a paper logbook (or worse, trying to recreate trips from memory), here are three excellent apps that Iowa small business owners are using:

  • Stride: Completely free with automatic GPS tracking and IRS-ready reports. Perfect for freelancers and small business owners. Download Stride

  • MileIQ: Great for regular routes with innovative recognition features. Free for 30 trips/month, premium plans start at $5.99/month. Visit MileIQ

  • Everlance: Ideal if you need expense tracking too. Links with bank accounts and suggests missed deductions. Free for 30 trips/month, premium at $8.99/month. Try Everlance


All three apps automatically track your drives, let you easily classify them as business or personal with a swipe, and generate IRS-compliant reports.


199A Qualified Business Income Deduction

Many Iowa small business owners aren't aware that this federal deduction can reduce taxable income by up to 20%. This applies to:

  • Sole proprietorships

  • S-corporations

  • Partnerships

  • LLCs are taxed as pass-through entities


Iowa Connection: While Iowa doesn't offer a corresponding state deduction for 199A, the federal savings are substantial. A profitable Iowa small business could save thousands annually.


Often-Overlooked Business Expenses

Business Insurance:

  • General liability insurance

  • Professional liability coverage

  • Workers' compensation premiums


Office Supplies and Software:

  • QuickBooks and other business software subscriptions

  • Office supplies (even if you work from home)

  • Computer equipment and software

💡 Make Sure Your QuickBooks is Capturing Every Deduction

Iowa-Specific Tax Credits Often Missed

New Jobs Tax Credit:

  • Available to businesses participating in Iowa's New Jobs Training Program

  • Maximum credit: $2,370 per new employee in 2025

  • Can be carried forward for up to 10 years


Investment Tax Credit:

  • Up to 10% of the qualifying investment in real property and equipment

  • Available through Iowa's High Quality Jobs Program

  • Carry-forward period of up to seven years


Common Filing Mistakes That Cost Money

Biennial Report Oversight: Iowa LLCs and corporations must file biennial reports. LLCs file in odd years (2025, 2027), corporations in even years. Missing this $30 filing can lead to administrative dissolution and reinstatement fees. Iowa biennial report requirements


Quarterly Estimated Tax Confusion: With Iowa's new 3.8% flat tax rate, many business owners are still calculating quarterly payments based on old rates, leading to overpayments that could be put to work in their business instead.


Record-Keeping Tips for Success

Digital Documentation:

  • Scan receipts immediately using smartphone apps

  • Maintain separate business bank accounts and credit cards

  • Use QuickBooks or similar software to categorize expenses automatically


Key Records to Keep:

  • All business-related receipts

  • Mileage logs for vehicle use

  • Bank and credit card statements

  • Invoices and contracts

Looking Ahead: Tax Planning for the Rest of 2025

With Iowa's new flat tax rate, tax planning is more straightforward but equally important. Consider:

  1. Timing Equipment Purchases: With bonus depreciation at 40% for 2025, consider whether to make major equipment purchases this year or wait. Bonus depreciation overview

  2. Income Timing: For cash-basis taxpayers, consider timing when you bill customers and pay expenses to optimize your tax situation.

  3. Retirement Contributions: SEP-IRAs and Solo 401(k)s offer significant deduction opportunities for small business owners.


Key Takeaways

Iowa's tax landscape has simplified with the flat 3.8% rate, but that doesn't mean tax planning is less important. Many Iowa small business owners are still operating under outdated assumptions about state tax law.

You could save thousands of dollars annually by keeping good records and understanding current Iowa tax law.


Questions to Ask Yourself

Before we wrap up, consider these questions:

  • Are you tracking all business-related vehicle expenses?

  • Have you properly documented your home office space?

  • Did you take full advantage of equipment purchases in recent years?

  • Are you aware of all Iowa tax credits available to your business?


Remember, tax law can be complex, and what applies to one business may not apply to another. When in doubt, consult a qualified tax professional who understands federal and Iowa tax requirements.
