IN THE KNOW WITH CTO: Many taxpayers avoid the home office deduction because they worry it is too complicated, too risky, or only available in very limited situations. Others claim it without realizing there are specific rules that must be met. The truth is: the home office deduction can be valuable when it applies—but the rules matter.

To qualify, the space generally must be used regularly and exclusively for business. A desk in a shared family room usually does not count. For those who qualify, the IRS also offers a simplified “standard deduction” option for home offices, which can make the calculation easier.

Some common myths include: “Claiming a home office automatically triggers an audit.” This is not true if you qualify and keep good records. Another is: “It’s not worth looking into.” Also not true as it can be a meaningful deduction for some self-employed taxpayers and small business owners.

If you are a client of ours, please know that we work diligently to make sure you are taking every deduction you are entitled to while also helping you stay compliant with the rules. If you aren’t a client but have questions, we are here to help. Please reach out to us by calling (508) 222-3005.

IN THE KNOW WITH CTO: Summer jobs are a great way for teens to build responsibility, earn spending money, and start learning lifelong financial habits. They can also bring up a few tax questions for parents. Here are a few things families with working-age children should keep in mind this summer:

▪️Withholding and filing: Many teens end up filing a tax return simply because federal or state income taxes was withheld and they need to claim a refund. If your teen expects to earn $8,000 or less for the year, it may be worth asking the employer to suppress income tax withholding so they keep more in each paycheck and avoid filing just to get their own money back.

▪️Roth IRA opportunities: If your teen has earned income, a Roth IRA may be a smart way to help them start saving early.

▪️Recordkeeping matters: Encourage your teen to save pay stubs, W-2s, 1099s, tip records, and notes on any cash or self-employment income. Good records make tax time easier and help families avoid surprises.

A summer job can be more than a paycheck—it can be a great first step toward financial confidence. If you have questions about your teen’s summer income, tax filing requirements, or whether a Roth IRA makes sense, we’re here to help. Call us at (508) 222-3005 with any questions.

As we celebrate Independence Day, this year carries special meaning as we mark the United States’ semiquincentennial – the 250th anniversary of the adoption of the Declaration of Independence. It is a meaning milestone to honor our nation’s founding principles, reflect on how far we’ve come, and appreciate the freedoms we continue to enjoy.

We are also reminded how fortunate we are to be part of a strong, supportive local community. From the small businesses that keep our neighborhoods moving to the families, friends, and neighbors who make this area feel like home, we are grateful to serve and grow alongside you.

We hope your holiday is filled with meaningful time with loved ones, safe celebrations, and appreciation for the freedoms we enjoy. The entire team from CTO wishes you and your family a happy, safe, and memorable Fourth of July!

IN THE KNOW WITH CTO: Renting out a vacation home, beach house, lake house, or even a spare room this summer? That extra income may come with tax reporting requirements.

The tax rules can depend on how many days the property is rented, how many days it is used personally, and which expenses are properly documented. Mortgage interest, real estate taxes, utilities, insurance, repairs, and other costs may all be part of the conversation, but the details matter. Keeping good records of rental dates, personal-use days, income received, and related expenses can help avoid surprises at tax time.

If you have questions about how vacation rental activity may affect your tax situation, we’re here to help. Please reach out to us at (508) 222-3005.

IN THE KNOW WITH CTO: A Roth IRA conversion can be a powerful move to create tax-free income in retirement and give you more flexibility in the future. This strategy is typically a great fit if you expect to be in a higher tax bracket later (career growth, Social Security, pensions, etc.), want to diversify your retirement savings between pre-tax and Roth for better tax control, have a lower-income year (job change, business loss, early retirement, etc.) and/or plan to leave assets to heirs and want tax-free distributions for beneficiaries (subject to rules).

By converting to a Roth IRA, you generally pay tax now so that qualified withdrawals later can be tax-free. This helps reduce future RMDs, create a tax-free cash flow during retirement and potentially lower Medicare premiums tied to taxable income. If you have thought about converting or would like to learn more about the benefits of Roth IRA conversions, call us at (508) 222-3005 and we will help you evaluate the tax impact as well as the best timing for your individual situation.

TOMMY’S TAX TIP: Having a will and an estate plan isn’t just smart—it’s the loving thing to do for the people you leave behind. It helps avoid surprises, reduces stress during an already emotional time, and makes sure your wishes are clearly documented. An estate plan can cover more than just a will—things like beneficiary designations, powers of attorney, healthcare directives, and how your assets are titled. We can help you get organized, coordinate with your attorney, and make sure your financial and tax details align so your plan works the way you intend. If you’ve been meaning to put a plan in place (or update an old one), we’re here to help you take the next step with confidence. Call us at (508) 222-3005 to get started.
