Running a business is expensive. You’re paying vendors, onboarding contractors, covering subscriptions, investing in marketing, keeping the lights on, and possibly wondering how your Uber charges tripled this month.
But here’s the silver lining: a lot of those expenses are tax-deductible. If you track them the right way, you could slash your tax bill, keep more money in the business, and avoid nasty surprises from the IRS.
The problem? Most entrepreneurs either aren’t tracking expenses correctly, or worse, they don’t track at all.
And when tax season hits, they’re stuck searching for a “tax preparer near me” or panicking about what counts, what doesn’t, and whether they’re about to be penalized for guessing.
At Insogna CPA, a top-tier Austin CPA firm, we work with business owners across industries to create real-time, audit-proof, stress-free systems for tracking and managing expenses. This blog lays out everything you need to know to clean up your records, maximize your deductions, and finally feel confident when tax time rolls around.
Why Expense Tracking Matters More Than You Think
Let’s start with the fundamentals.
Your expense tracking isn’t just for taxes. It impacts:
● Your cash flow
● Your profit margin
● Your ability to make decisions
● Your investor or loan-readiness
● Your compliance with IRS rules
Every dollar you track (accurately) is a dollar you might not have to pay taxes on. And every expense that’s not properly categorized could trigger red flags with your tax advisor near you or, worse, the IRS.
A well-built expense tracking system helps you:
● Reduce taxable income
● Identify overspending
● Project future budgets
● Maintain cleaner financial statements
● Simplify year-end tax prep for your certified public accountant near you
Yet many businesses don’t realize that expense tracking is the foundation of good tax planning, not something you fix in March.
What Counts as a Deductible Business Expense?
If you’ve ever asked, “Can I deduct this?” the answer depends on one word: intent.
The IRS allows deductions for any ordinary and necessary expenses related to operating your business. That’s intentionally vague and where smart tracking and expert guidance comes in.
Let’s walk through some categories you should be monitoring:
1. Home Office Expenses
With more businesses operating remotely than ever, home office deductions are back in the spotlight.
You can deduct:
● A percentage of your rent or mortgage (based on square footage)
● Utilities like electricity, internet, and insurance
● Repairs and maintenance (for the home office area only)
● Office furniture, computers, desks, printers, etc.
Important caveat: The space must be used exclusively for business. Not part-time, not your dining table, not the guest room that doubles as a yoga studio.
Work with an Austin TX accountant to make sure you’re calculating your deduction correctly using either the simplified method or the actual expense method.
2. Business Travel and Meals
Traveling for business? Attending a conference? Taking a client out for lunch? These may all be partially deductible but you need to know the rules.
Deductible items include:
● Airfare, hotels, car rentals
● Taxis, rideshare apps, tolls, parking
● 50% of meals with clients, partners, or during travel
Tip: Business meals must be “ordinary, necessary, and directly related” to your business. Document the who, where, and why for each.
Not deductible: Entertainment expenses (sporting events, concerts, club memberships) were eliminated under the 2017 Tax Cuts and Jobs Act.
3. Marketing and Advertising
You’re investing to grow, and the IRS considers that fair game.
Fully deductible expenses include:
● Facebook, Google, LinkedIn ads
● Website hosting, development, SEO
● Branding and graphic design
● Email marketing platforms like Mailchimp or ConvertKit
● Print materials, trade shows, sponsorships
Don’t forget to document any freelance or agency support with contracts and invoices. Your CPA office near you will thank you for it later.
4. Software and Subscriptions
It may not feel like much month to month, but all those SaaS tools add up and they’re 100% deductible.
Track:
● Accounting platforms (QuickBooks, Xero)
● Zoom, Slack, G Suite, Office 365
● Project management tools (Asana, ClickUp, Monday.com)
● E-signature tools (DocuSign, HelloSign)
● CRM software (HubSpot, Salesforce)
You’d be surprised how many business owners forget to record their annual renewals. These are easy wins when reviewed with your Austin tax accountant.
5. Payroll and Contractor Costs
If you pay people to help you run your business, those costs are deductible but you need to classify them correctly.
Deductible costs include:
● Salaries and wages
● Employer-paid payroll taxes
● Health insurance and benefits
● Payments to freelancers or independent contractors
Watch out: Misclassifying W-2 employees as 1099 contractors can trigger audits and back taxes. Always check classification rules with a certified CPA near you or enrolled agent.
6. Vehicle Use and Mileage
If you use a personal or business-owned vehicle for work purposes, you can deduct vehicle expenses using one of two IRS-approved methods:
● Standard mileage rate — 67 cents per mile for business use in 2025 (per IRS guidelines)
● Actual expense method — includes fuel, maintenance, insurance, registration, and depreciation
You must choose one method per vehicle, per tax year, and you need to consistently track your business mileage throughout the year.
What You Can’t Deduct (Even if You Think It’s “Business-ish”)
We’ve heard them all. Unfortunately, the following don’t count:
● Personal Netflix, Spotify, or streaming services
● Clothing (unless it’s branded uniforms used exclusively for work)
● Commuting from home to a regular office
● Client entertainment (post-2017 tax reform)
● Late payment penalties or traffic tickets
A good rule of thumb? If you’re stretching to justify it, call your tax advisor in Austin first.
Common Mistakes We See And How to Avoid Them
Even entrepreneurs with the best intentions fall into common traps. Here are the expense tracking errors we correct most often for clients:
1. Mixing Business and Personal Spending
Using one bank account for both = audit risk. Open a separate business account and dedicate a credit card for work-related purchases.
2. Not Saving Receipts
The IRS requires substantiation for many deductions. Snap photos, upload PDFs, and store everything digitally.
3. Waiting Until Tax Season
Organizing a year’s worth of expenses in Q1 is inefficient, overwhelming, and almost guarantees missed deductions. Track in real time.
4. Ignoring Small Expenses
A $9 Canva charge here, a $12 client coffee there—it adds up. Don’t discount low-dollar items.
5. Misclassifying Workers
Use Form W-9 for independent contractors. File 1099s. Keep payroll clean. When in doubt, your CPA firm in Austin Texas can help.
Why Clean Expense Tracking Is the Foundation of Tax Strategy
Here’s the bigger picture:
If your books aren’t accurate, your tax accountant near you can’t do their job properly. They’re stuck cleaning up reports instead of finding tax-saving opportunities.
Solid, proactive expense tracking helps your CPA:
● Strategize entity changes (e.g. LLC to S-Corp)
● Maximize retirement contributions
● Optimize depreciation schedules
● Avoid underpayment penalties
● Identify R&D tax credits and FBAR filing requirements
Your CPA-certified public accountant isn’t just a form-filer. They’re a strategist. But they can only advise based on clean, timely data and that starts with your expenses.
