Start the New Year Right: Strategic Tax Preparation

As the year winds down, tax season starts to loom. For high-net-worth individuals, business owners, and multigenerational families, early preparation isn’t just smart—it’s essential. Proactive tax planning can lead to meaningful savings, smoother filings, and more strategic financial decisions.

Here’s your comprehensive guide to preparing for tax season, with a focus on gathering the right documents, avoiding common pitfalls, and maximizing your tax strategy.

1. Gather the Right Documents Early

Begin with a checklist. Whether you work with a CPA, financial advisor, or estate planning attorney, having all documentation ready in advance will streamline the process.

Key documents to collect:

• Income statements: W-2s, 1099s (freelance, dividends, interest, etc.), K-1s from partnerships or trusts
• Investment documents: Year-end brokerage statements, realized gains/losses, crypto transactions
• Business documents: Profit and loss statements, balance sheets, payroll records, 1099s issued
• Real estate and mortgage info: Form 1098, property tax receipts, closing statements for purchases/sales
• Charitable giving: Receipts or acknowledgment letters for all donations
• Retirement contributions and distributions: 5498s and 1099-Rs for IRAs, 401(k)s, etc.
• Education and medical expenses: 1098-T for tuition, HSA distributions, and receipts for deductible expenses

2. Leverage Last-Minute Tax Strategies

There may still be time before December 31 to implement smart strategies:

• Max out retirement contributions (especially SEP IRAs or solo 401(k)s for business owners)
• Make charitable contributions (consider donor-advised funds for flexibility)
• Harvest tax losses to offset gains
• Review year-end bonuses or distributions to align with your tax bracket goals

3. Avoid These Common Mistakes

Even seasoned professionals can overlook key steps:

• Missing basis information for asset sales, leading to overstated gains
• Forgetting to report foreign accounts or crypto holdings (both carry strict IRS rules)
• Not coordinating with your estate or business planning

An integrated approach ensures your tax plan supports your broader legacy and financial goals.

4. Plan Ahead for Next Year

While you finalize this year’s filings, it’s the perfect time to:

• Adjust your estimated tax payments if your income is variable
• Revisit your entity structure for tax efficiency (especially after a liquidity event)
• Schedule a strategy session to align your investment, business, and estate plans
