Tax season has a way of arriving faster than anyone expects. One day you’re navigating Q4 close-outs and planning for the new year, and the next, deadlines are looming and your inbox is full of forms you’re not sure what to do with. For small business owners, this time of year can feel overwhelming, but it doesn’t have to.
Whether you’re a sole proprietor filing your first Schedule C, an LLC managing quarterly obligations, or an S-Corp owner balancing salary and distributions, there are smart steps you can take right now to make this season smoother, faster, and more financially beneficial.
Here’s your practical, no-fluff guide to surviving, and thriving this tax season.
Before any numbers get crunched, you need to gather your records. Disorganized documentation is one of the top reasons tax filings get delayed, trigger errors, or leave money on the table. Here’s what to pull together:
Income Records:
Expense Records:
Other Key Documents:
If your books are clean and up to date, this process takes hours. If they’re not — this is your reminder to never let it get this far again (and to call us, because we can help you catch up quickly).
One of the most common mistakes small business owners make is not understanding how their business structure affects their taxes. Your entity type determines what forms you file, when you file, and what deductions you can take.
Sole Proprietors and Single-Member LLCs report business income on Schedule C of their personal tax return. Your net profit is subject to both income tax and self-employment tax (which covers Social Security and Medicare). The SE tax rate is 15.3% on the first $168,600 of net earnings, a significant amount many first-time business owners don’t anticipate.
Partnerships and Multi-Member LLCs file a Form 1065 (partnership return), and each partner receives a Schedule K-1 that flows to their individual return. The partnership itself doesn’t pay federal income tax — the income passes through to each partner.
S-Corporations also pass income through to shareholders via K-1s, but they come with a critical tax-planning tool: the ability to split income between a reasonable salary (which is subject to payroll taxes) and distributions (which are not). Getting this split right can save you thousands — but it has to be done correctly, and the IRS scrutinizes unreasonably low salaries.
C-Corporations pay corporate tax at the entity level (currently a flat 21% federal rate) and then shareholders pay again when dividends are distributed — the so-called “double taxation” that most small businesses seek to avoid by choosing pass-through structures.
If you’re unsure whether you’re in the right structure, tax season is actually a great time to revisit that question with your CPA.
Every legitimate deduction reduces your taxable income, and that directly lowers your tax bill. Here are some commonly overlooked deductions for small business owners:
Home Office Deduction: If you use part of your home exclusively and regularly for business, you may qualify. You can use the simplified method ($5 per square foot, up to 300 sq ft) or the actual expense method for a larger deduction.
Health Insurance Premiums: Self-employed individuals can often deduct 100% of health, dental, and vision insurance premiums for themselves and their families; even if you don’t itemize.
Retirement Contributions: Contributions to a SEP-IRA, SIMPLE IRA, or Solo 401(k) are deductible and can dramatically reduce your taxable income. For 2025, SEP-IRA contributions can be up to 25% of net self-employment income, capped at $70,000.
Section 179 and Bonus Depreciation: If you purchased equipment, machinery, or even certain software during the year, you may be able to deduct a significant portion (or all of it) immediately rather than depreciating it over multiple years.
Professional Services: Fees paid to accountants, attorneys, bookkeepers, and consultants are fully deductible business expenses. Yes, this means your CPA fees are tax-deductible.
Business Meals: 50% of business-related meals are deductible when there’s a clear business purpose and you keep documentation of who you met with and why.
Education and Training: Courses, certifications, subscriptions, and conferences that are directly related to your current business are deductible.
Don’t guess at these. Work with a qualified CPA who can ensure you’re claiming every deduction you’re legally entitled to, without the risk of overclaiming.
Here’s something many business owners miss: the IRS expects you to pay taxes as you earn, not just in April. If you’re self-employed or have significant business income, you’re typically required to make quarterly estimated tax payments.
The 2026 estimated tax payment schedule is:
Missing these payments can result in underpayment penalties — even if you pay in full at tax time. A good CPA will calculate your estimated payments as part of your tax planning process, so you’re never caught off guard.
Life happens. If you’re not ready to file by April 15, you can file a Form 4868 to get an automatic six-month extension, pushing your deadline to October 15. However, and this is critical — an extension to file is not an extension to pay. Any taxes owed are still due by April 15. If you underpay, you’ll accrue interest and possibly penalties on the balance.
The smart move: estimate what you owe and make a payment with your extension request, even if it’s not exact. It’s better to slightly overpay and get a refund than to underpay and owe interest.
