If you need assistance or expert advice, feel free to book a session for Personal Tax Preparation or Business Tax Preparation and get the help you need to maximize your savings.
Key 2025 numbers at a glance
- Business mileage: 70¢/mile
- Home office (simplified): $5/sq ft up to 300 sq ft (max $1,500)
- 401(k) employee deferral limit: $23,500 (higher catch-up $11,250 for ages 60–63)
- IRA contribution limit: $7,000 ($8,000 age 50+)
- De minimis safe harbor: expense items ≤ $2,500 (if no AFS)
We’ll confirm which rules apply to your situation.
Mistake 1: Waiting until filing time to “optimize”
Significant savings typically occur well before you actually file your taxes—this is achieved by carefully tracking and capturing your mileage expenses, selecting the most advantageous home-office deduction method, and making timely retirement contributions that meet all applicable deadlines. Taking these proactive steps in advance can maximize your potential tax benefits and reduce your overall tax liability.
Fix: Set a simple quarterly routine: (1) update mileage/app logs, (2) reconcile books, (3) review retirement contributions (401(k)/IRA), (4) estimate taxes. If you’re busy, we can set this up inside our Accounting & Bookkeeping package.
Mistake 2: Using the wrong deduction method
Many filers leave money on the table by choosing the wrong method: mileage vs. actual vehicle expenses, or simplified vs. actual home-office. The best choice depends on your usage and records.
- Mileage: 70¢/mile for 2025—easy if you keep a log.
- Home office simplified: $5/sq ft up to 300 sq ft—great if you want less paperwork.
- Actual-expense methods: often better if costs are high and records are clean.
Fix: We’ll run both methods and use the larger, audit-safe deduction during your Personal Tax Preparation or Business Tax Preparation.
Mistake 3: Poor timing on equipment/software purchases
Deductions are influenced significantly by the exact timing of when the property is officially placed in service. For instance, if you purchase an asset on December 31 but do not actually put it into service until sometime in January, this delay can result in the deduction being postponed and claimed in the following tax year instead of the current one. There are specific tax rules and provisions, such as Section 179 expensing and bonus depreciation, that can provide opportunities to accelerate these deductions. However, it is important to keep in mind that these options come with various limits, qualifications, and eligibility criteria that must be carefully considered before applying them.
Fix: Before year-end, review your pipeline and decide what to buy and when to place in service. We’ll map the best approach during Business Consulting.
Mistake 4: Mixing personal and business finances
Commingled accounts often result in missed deductions and create messy, disorganized records that can be difficult to manage effectively. This lack of clear separation also significantly weakens your position if the IRS requests documentation or support during an audit or review process. Maintaining distinct accounts is essential for accurate record-keeping and ensuring you can confidently substantiate your financial claims.
Fix: Use dedicated business banking and credit cards exclusively for your company transactions, and maintain a straightforward, consistent monthly close process. If you find yourself falling behind, don’t worry—our comprehensive Accounting & Bookkeeping service is designed to help you get caught up quickly, ensuring all your financial records are accurately reconciled and up to date.
