Hammernik’s 11 Expert Tips To Audit-Proof Your Business

How can I make sure I don’t get audited?

What are my chances of getting an audit?

If I take that deduction, will it raise a red flag?

These are just a few of the questions we receive, probably about every week from our Waukesha County business clients (there’s more, but I don’t want to scare you — or give you any ideas).

And look — I’m not exasperated by the questions. But receiving these questions enough, as I do, means that I should probably write about it.

So, I’ve put together a primer for my business-owner clients and friends on avoiding audits, completely.

Here it is — and don’t make the mistake in thinking that just because the IRS budgets have decreased recently for this stuff, that nobody ever gets audited. Believe me, that’s not the case…

“Some people come into your life as blessings, others come into your life as lessons.” – Mother Teresa

I’ve seen a fair share of audits, my friend. And, of course, nobody likes dealing with them.

That said, there are some pretty basic steps which YOU, as a business owner, can take to ensure this doesn’t happen to you. Some of these apply to those of my clients and friends who filed an extension (as they deal with your actual return), while others are year-round necessities.

But I will say right up front: If this is overwhelming to you, there’s a simple solution — have us handle all of it for you. But if you want to tackle it all yourself, here’s what you should be doing…

1. Make sure that any third-party income and reports agree with your records.

2. Make sure you have selected the correct forms and schedules to fill out. Ask yourself: Do the forms apply? Am I stretching the situation? Are there credits that I am entitled to whose forms I haven’t included, but need to?

3. Keep track of bank deposits so that all items will be easy to trace. Write the source of the check directly on the deposit slip , especially transfers between accounts, so that these are not inadvertently counted as income.

The first thing tax auditors request are your checking, savings, and investment accounts. They then proceed to do a total cash receipts analysis, comparing the total to the gross income shown on your tax return. By marking every deposit slip, you know where to look for further documentation to support your notation, and the auditor will have the trail in front of him or her, for the source of the unusual nontaxable receipts such as insurance recoveries, loans, gifts, and inheritances. Surprisingly, it’s not that much work, and is worth the effort.

4. Always keep your checking and savings accounts free of irregularities. Be sure you can explain large bank deposits and increases (especially sudden ones) in your net worth. WARNING: If you have unreported income of more than 25% of your adjusted gross income, the auditor may turn your case over to the CID. If you suspect this may occur, do not provide any leads to the auditor regarding the sources of the unexplained deposits. The burden of proof is on the IRS. You do not have to provide leads that make their job easier.

5. Keep your business and personal accounts separate.

6. If you know you are going to take a business deduction, pay for it by check.

7. Know the proper time to file. IRS computers are not programmed to review only those returns received before April 15th. So who is to say that late returns, those filed after April 15th, won’t be audited, or will be audited less than returns mailed earlier?

8. Be thorough. Don’t leave out any information. Sign where you are supposed to.

9. Be neat.

10. Check your mathematics.

11. Balance your total deductions with your income. Extensive deductions that add up to a substantial portion of your total income are audit flags.

Good tax preparers will make you “audit proof” while being extremely aggressive with your business deductions. A good tax preparer will also save you thousands of dollars a year and give you the security of knowing that all your deductions are legally defensible. We know that’s why you’ve chosen to rely on us … and we’re glad you rely on us to help you be Audit-Proof.

But, let’s posit that for some strange reason you (or a friend) did NOT choose us to file your taxes this year … well, then there’s this:

Unlock the Strategic Path to Tax Savings
By Brad Tobin October 1, 2025
The One Big Beautiful Bill Act has reshaped tax law in ways that directly affect real estate investors. While many changes apply broadly to business owners, real estate stands out as one of the biggest winners, with some important caveats. Here’s what you need to know: 1. 100% Bonus Depreciation is Permanent One of the most valuable tools for real estate investors has been bonus depreciation, allowing immediate write-offs of certain improvements and property components. The new bill makes 100% bonus depreciation permanent. What this means: Cost segregation studies remain a powerful way to accelerate deductions. Investors purchasing or improving property over the next few years can still capture large up-front tax benefits. 2. 1031 Exchanges Fully Preserved There was speculation that like-kind exchanges (1031s) might be curtailed or eliminated. The new law instead fully preserves 1031 exchanges for real estate. What this means: Investors can continue deferring capital gains taxes by rolling proceeds from one property into another. Combined with extended bonus depreciation, this creates opportunities for “swap ‘til you drop” strategies, exchanging property while deducting improvements and eventually receiving a step-up in basis at death. 3. Opportunity Zone Changes Opportunity Zones (OZs), designed to incentivize investment in designated low-income areas, saw important updates under the new law. What changed: The program sees a new 5 year rolling deferral period starting on January 1, 2027, giving investors more time to deploy capital and meet compliance deadlines with basis step ups. What this means: Investors sitting on capital gains still have a chance to defer and potentially reduce those taxes by investing in Qualified Opportunity Funds in 2027. Longer timelines mean more flexibility in planning, but reporting compliance will become more important. 4. Energy-Efficient Provisions Narrowed Under prior law, energy-related credits and deductions had expanded significantly. The new bill rolls some of these back, especially for residential projects, while still preserving limited opportunities for commercial property. What changed: Section 179D (commercial building energy-efficiency deduction) & 45L (new energy efficient home credit) is preserved, but only through June 30, 2026 for projects that begin construction before then. After that, it phases out. Many residential energy credits (solar, HVAC, insulation) are being eliminated or sunset after 2025. Commercial Battery Storage Credit is still available through 2032 and will start to phase out in 2033 and 2034. What this means: Commercial property owners considering efficiency upgrades should act soon there is a clear window of opportunity before these provisions disappear. Residential investors should not rely on tax credits for green improvements going forward. The One Big Beautiful Bill Act creates new opportunities but also deadlines for real estate investors. Extended bonus depreciation and preserved 1031 exchanges keep powerful tax strategies on the table. Opportunity Zones have been given new life, while energy-efficient incentives are on the clock. The key takeaway: timing matters more than ever. Planning acquisitions, improvements, and sales with these changes in mind can mean the difference between maximizing tax savings or missing out. If you’re a real estate investor and want to understand how these provisions apply to your portfolio, let’s connect to review your specific situation.

In July 2025, Congress passed and the President signed into law the One Big Beautiful Bill Act (OBBBA), bringing major changes to the U.S. tax code that significantly impact businesses, investors, pass-through entities, and estate planning. Many provisions build on the Tax Cuts and Jobs Act (TCJA). Some are permanent, others temporary, and all require careful planning to maximize opportunities and avoid pitfalls. If you are a business owner, investor, or considering succession or estate planning, these changes could affect you directly. Key Business & Investment Tax Changes QBI Deduction Made Permanent ● 20% deduction for pass-through entity income (LLCs, S-corps, partnerships, sole proprietorships) is now permanent. ● Income thresholds for specified service trades or businesses (SSTBs) increased for 2025 ($394,600 for joint filers and $197,300 for other taxpayers). ● Starting in 2026, phase-in ranges expand: $150k for joint filers and $75k for others. ● Taxpayers with at least $1,000 in QBI may claim a minimum $400 QBI deduction. 100% Bonus Depreciation Permanently Extended ● Businesses can fully deduct qualifying property (equipment, vehicles, and certain buildings) placed in service after Jan 19, 2025. ● Manufacturing buildings qualify if placed in service before Jan 1, 2031. Qualified Opportunity Zones (QOZs) ● Program is now permanent, with new 10-year designations beginning Jan 1, 2027. Estate, Gift, and Succession Planning ● Lifetime estate and gift tax exemption increased to ~$15 million per person (indexed for inflation beginning in 2026). ● Adjustments to Qualified Small Business Stock (QSBS) for shares issued after July 4, 2025. Tip Credit Expansion ● FICA tip credit extended to beauty service businesses. Other Key Provisions ● Restored Research and Development expensing (Section 174). ● Interest deduction changes (ATI excludes depreciation, amortization, or depletion). ● Higher Section 179 deduction and phase-out thresholds. ● Expanded Low Income Housing Tax Credit allocations. ● Clean Energy Tax Credit changes: Section 45L and 179D repealed after June 30, 2026. Considerations & Challenges ● Some provisions are temporary (e.g., certain deductions and caps), so timing is critical. ● Income phaseouts may limit benefits for high-income pass-through owners. ● Increased compliance complexity (e.g., amended returns, documentation) will be important. ● Real estate ownership structures and financing choices may need reevaluation in light of new depreciation and interest rules. Planning Opportunities for Businesses & Investors Accelerate Capital Expenditures Investing in equipment, vehicles, or eligible buildings now can provide immediate tax benefits through 100% bonus depreciation. Optimize Business Structure for QBI Assess ownership, entity type, and income levels to maximize the 20% deduction. Service businesses might gain advantages by restructuring to distinguish between qualifying and non-qualifying activities. Estate & Succession Planning Take advantage of the higher exemption to transfer assets via gifts or trusts while the thresholds are still beneficial. Consider Qualified Small Business Stock (QSBS) opportunities if you are investing in or selling small business shares. Leverage Tax Credits & Incentives Investigate possibilities in affordable housing and Qualified Opportunity Zones, but ensure compliance with updated documentation requirements. Cost Segregation for Real Estate Think about conducting cost segregation studies to enhance depreciation benefits on properties. Model Income Scenarios Create multi-year projections to optimize the timing of income, deductions, and asset acquisitions to avoid crossing phaseout thresholds. What’s Next? The One Big Beautiful Bill Act transforms the tax environment for businesses and investors alike. Featuring permanent QBI deductions, reinstated R&D expensing, and bonus depreciation, it unlocks extraordinary chances to minimize taxable income. Additionally, enhanced estate and gift exemptions offer robust strategies for effective succession planning. However, these advantages won’t maximize themselves. Considerations such as timing, entity structure, and integrated planning are crucial — as every choice can significantly alter your tax responsibilities. To understand how these developments affect your unique circumstances, reach out to us at Hammernik & Associates. Together, let’s devise a strategy that strategically positions your business for success in 2025 and beyond.
