Clean Books, Clear Decisions

Before any tax strategy can work, your numbers must be trustworthy. Reconciling bank, card, and loan balances, clearing aging transactions, aligning the chart of accounts, and correcting inventory counts create the foundation for every decision you make. Owners who invest focused hours here reduce surprises later, accelerate their returns, and present a clean story to advisors and auditors. We share practical steps, common pitfalls, and helpful automations so you finish the rush with clarity rather than guesswork.

Bank, Card, and Loan Reconciliations

Match every transaction to statements, resolve duplicate imports, and investigate unexplained balances before December closes. Reconciled accounts reveal missing income, uncaptured expenses, and lingering errors that compound into larger tax problems. Document your adjustments with short notes, then lock prior periods to prevent accidental changes and maintain a defensible audit trail that supports accurate filings and confident decision-making.

Chart of Accounts Tune-Up

Merge redundant expense categories, standardize naming, and split out high-impact items like software, subcontractors, and travel to improve visibility and deductions. A tidy chart clarifies where cash actually goes, strengthens trend analysis, and simplifies year-end mapping to tax lines. Add account numbers, archive old categories, and create rules that automatically categorize recurring transactions with consistent accuracy.

Inventory Truth and COGS Accuracy

Conduct a physical count, reconcile shrinkage, and verify purchase costs so cost of goods sold reflects reality. Adjust for obsolete items and document write-downs with dates, reasons, and supporting evidence. Align inventory methods with your accounting system, confirm vendor terms, and ensure landed costs are captured. Accurate inventory boosts margins, protects deductions, and avoids painful rework during filing season.

Deduction Power Moves Before Midnight

Year-end is prime time to capture deductions and position investments intelligently. Consider timing significant purchases, evaluating capitalization thresholds, and confirming documentation for common write-offs. Coordinate with your advisor to ensure moves align with cash flow, entity status, and long-term plans. The right steps can reduce taxable income, strengthen operations, and set you up for a smoother filing experience without scrambling in January.

Expense vs. Capitalize: The Smart Split

Decide which purchases to expense immediately and which to capitalize based on materiality policies, expected asset life, and strategic tax goals. Proper documentation, invoices, and in-service dates matter. Review de minimis safe harbor elections, confirm capitalization policies in writing, and keep a fixed asset register updated. A thoughtful approach preserves cash, reduces errors, and keeps depreciation schedules defensible.

Hidden Write-Offs Many Owners Miss

Revisit home office allocations, business mileage, mobile devices, job-related education, and professional subscriptions. Confirm travel and meals logs, separate client entertainment, and capture small but meaningful recurring costs that get lost in general categories. Digitize receipts, attach them to transactions, and add brief notes describing business purpose. Small improvements add up, especially during the hectic year-end push.

Safe Harbor Rules Without the Jargon

Use safe harbor methods to reduce penalty risk by paying a percentage of your prior-year tax or your current-year liability. Run projections with conservative assumptions, and adjust quarterly. If income spiked, plan a final estimated payment. Document calculations, payment dates, and confirmations, creating a clear trail that satisfies both your future self and your tax preparer.

Timing Income and Expenses, Legally

Consider sending December invoices closer to month-end, or accelerating necessary purchases you planned for early next year, if it aligns with cash realities and accounting method rules. Avoid artificial transactions; focus on genuine business needs. Coordinate with vendors, confirm delivery dates, and verify that assets are placed in service. Responsible timing smooths cash, supports deductions, and withstands scrutiny.

Build a Dedicated Tax Reserve

Open a separate savings account labeled for tax payments and fund it automatically each week. Tie contributions to a percentage of revenue so the reserve grows with sales. Visibility reduces stress, deters accidental spending, and ensures funds are available for estimates or balance due. Share access rules with your team to protect intent and prevent leakage.

People, Payroll, and Paper Trails

Year-end payroll and contractor reporting demand precision. Reconcile wages, benefits, and withholdings; confirm addresses; and prepare W-2s and 1099-NECs on time. Review worker classification, fringe benefits, and garnishments while checking state requirements. Tight documentation minimizes reprints, penalties, and employee frustration. A careful close also improves onboarding and reporting next year, reducing administrative drag when business should be moving forward.

Entity Choices and Retirement Levers

Your legal structure and retirement plan shape taxes, compliance, and cash flow. Confirm whether your current entity still suits your size, margins, and goals, and consider reasonable compensation for owner-employees. Explore retirement options that allow significant pre-tax or Roth contributions. Coordinate deadlines, payroll integration, and plan documents so contributions count and audits go smoothly, supporting long-term wealth building.

Confirm the Right Entity for the Next Year

Evaluate whether pass-through status, corporate treatment, or a change in election could reduce taxes or simplify compliance. Consider growth, distributions, and administrative complexity. Ensure ownership records, minutes, and agreements are current. Plan ahead for election deadlines. Document your analysis so future decisions reference today’s rationale rather than hurried guesswork during filing crunch time.

Set Up or Supercharge Your Retirement Plan

Compare SEP IRAs, SIMPLE IRAs, and Solo 401(k)s based on contribution limits, deadlines, and payroll coordination. Clarify employer versus employee portions, eligibility rules, and documentation. Automate contributions and track year-to-date totals to avoid errors. Retirement funding strategically reduces taxes while supporting personal goals, creating stability that carries you confidently through busy seasons and market surprises.

Optimize QBI with Wages, Basis, and Planning

Review the qualified business income deduction mechanics, including the interaction with wages, basis, and potential limitations. Forecast profit, run scenarios, and adjust wages or distributions where appropriate and compliant. Keep supporting schedules and memos detailing assumptions and decisions. This preparation helps maximize available benefits while giving you clarity when questions surface during review or an audit.

Security, Systems, and a Filing Countdown

Protect sensitive data, streamline workflows, and create a calendar that guarantees nothing slips. Digitize documents, restrict access, and back up encrypted files. Map responsibilities across your team, then schedule deadlines, reminders, and extension contingencies. These habits reduce last-minute chaos and make collaboration with your accountant faster, friendlier, and far more accurate during the hectic start of the year.

A Practical Document Retention Playbook

Define how long you retain bank statements, payroll records, tax returns, and supporting documents. Use consistent folder naming and version control. Store receipts with transactions and tag by vendor and year. Enforce permissions so only the right people see sensitive data. A simple, shared playbook multiplies everyone’s effectiveness during reviews and preparation.

Automate the Repetitive, Audit the Exceptions

Deploy bank rules, receipt capture, and vendor bills automation to shrink manual work. Schedule monthly reviews to spot anomalies and correct them early. Build dashboards showing unpaid bills, uncategorized transactions, and approaching deadlines. Automation handles volume, while exception reviews preserve quality. Together they reduce stress and free time for decisions that actually move the business forward.
