Tax Planning Secrets Revealed: What New Haven CPAs Don't Want You to Know About Year-End Strategies

Let's get something straight right off the bat – there aren't really "secrets" that tax professionals are hiding from you. What we're about to share are well-established strategies that many New Haven taxpayers simply aren't aware of or haven't implemented yet. Consider this your wake-up call before December 31st hits.

The Reality Check: Why Most People Miss These Opportunities

The biggest "secret"? Most taxpayers wait until March to think about taxes, when the real money-saving moves happen in the final weeks of December. While everyone's focused on holiday shopping, smart taxpayers are executing strategies that can save thousands on their 2025 tax bill.

Jose Morales, owner of Jose's Tax Service in New Haven, puts it simply: "Every December, I watch clients leave money on the table because they didn't plan ahead. The strategies we're sharing aren't hidden – they're just not widely implemented."

Strategy #1: Accelerate Your Business Deductions Before Year-End!

If you're a business owner, December is your last chance to reduce your 2025 taxable income. Here's what you need to do before the calendar flips:

Purchase equipment and take advantage of bonus depreciation. The bonus depreciation rate is being phased out, dropping from 80% in 2025 to 60% in 2026. This means you can still write off 80% of qualifying equipment purchases immediately in 2025.

Prepay business expenses. Consider paying January's rent, insurance premiums, or subscription services before December 31st. These legitimate business expenses can be deducted in 2025 if paid by year-end.

Maximize your Section 179 deduction. For 2025, you can deduct up to $1,160,000 in qualifying equipment purchases. This is significantly higher than bonus depreciation and applies to both new and used equipment.

Strategy #2: The QBI Deduction Most New Haven Business Owners Ignore

The Qualified Business Income (QBI) deduction allows eligible business owners to deduct up to 20% of their qualified business income. Here's what many miss:

Income timing matters. If you're approaching the taxable income thresholds ($191,950 for single filers, $383,900 for married filing jointly in 2025), consider deferring income to 2026 or accelerating deductions to stay below these limits.

W-2 wages and qualified property limitations. Above the threshold amounts, your QBI deduction is limited by W-2 wages paid or qualified property held by the business. Planning around these limitations can maximize your deduction.

Multiple business strategy. If you have multiple businesses, some profitable and others showing losses, the aggregation rules can work in your favor for QBI calculations.

Strategy #3: Retirement Account Contributions That Go Beyond the Basics

While most people know about 401(k) contributions, here are the advanced moves:

SEP-IRA contributions for business owners. You can contribute up to 25% of compensation or $69,000 for 2025, whichever is less. The key? You have until your tax filing deadline (including extensions) to make these contributions.

Solo 401(k) for side hustlers. If you have self-employment income, you can establish a Solo 401(k) and contribute both as an employee and employer. For 2025, this allows contributions up to $23,000 as an employee, plus up to 25% of net self-employment income as an employer contribution.

Backdoor Roth conversions. If your income is too high for direct Roth IRA contributions, you can contribute to a traditional IRA and immediately convert to a Roth IRA.

Strategy #4: Tax Loss Harvesting and Capital Gains Management

December is the final month to implement capital gains and loss strategies:

Harvest investment losses. Sell investments that have declined in value to offset capital gains. You can deduct up to $3,000 in net capital losses against ordinary income annually.

Avoid the wash sale rule. Don't repurchase the same or substantially identical security within 30 days of the sale, or the loss will be disallowed.

Consider Roth conversions during market downturns. If your investment accounts are down, it might be an optimal time to convert traditional IRA funds to a Roth IRA at a lower tax cost.

Strategy #5: Health Savings Account Triple Tax Advantage

HSAs are often called the ultimate tax-planning tool, yet many New Haven residents underutilize them:

2025 contribution limits. $4,150 for individual coverage, $8,300 for family coverage, plus an additional $1,000 catch-up contribution if you're 55 or older.

Triple tax benefit. Contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. After age 65, you can withdraw funds for any purpose (taxed as ordinary income, like a traditional IRA).

Strategic funding. You have until April 15, 2026, to make 2025 HSA contributions, giving you flexibility in timing.

The 2025 Tax Law Changes You Need to Know

The One Big Beautiful Bill Act (OBBBA) signed in July 2025 brought several changes affecting year-end planning:

Extended QBI deduction. The 20% deduction for pass-through entities has been extended with some modifications to the income thresholds.

Enhanced research and development credits. The R&D tax credit has been expanded for small businesses, making year-end R&D expenditures more valuable.

Energy efficiency incentives. New credits for energy-efficient business equipment and home improvements provide additional deduction opportunities.

State-Specific Considerations for Connecticut Residents

Connecticut has its own tax planning opportunities that many overlook:

Connecticut earned income tax credit. This state credit is based on the federal earned income tax credit and can provide additional refunds for eligible taxpayers.

Property tax credit program. Connecticut homeowners may be eligible for property tax credits that can be claimed on their state income tax return.

Angel investor tax credit. Connecticut offers tax credits for investments in qualified small businesses, which can be particularly valuable for high-income earners.

Action Items for the Next 30 Days

Here's your December checklist:

1. Review your business equipment needs and make qualifying purchases before December 31st
2. Calculate your projected income to determine optimal timing for income and deductions
3. Maximize retirement account contributions for both you and your spouse
4. Implement tax loss harvesting strategies in your investment accounts
5. Prepay deductible expenses such as state and local taxes (up to the $10,000 limit)
6. Consider charitable giving strategies including donor-advised funds or charitable remainder trusts

Why These Strategies Work Best with Professional Guidance

While these strategies are publicly available, implementing them correctly requires understanding your specific situation. The interaction between federal and state taxes, the timing of income recognition, and the coordination of multiple strategies can significantly impact your results.

At Jose's Tax Service, we see the difference proper year-end planning makes for our New Haven clients. The families and business owners who implement these strategies consistently save thousands compared to those who only think about taxes during filing season.
