Summer Activities and Taxes – Did You Know?

Summer is a time to relax and have fun, but some seasonal activities may have tax consequences. Being aware of them now may save you time and hassle later.

If your child attends a day camp so you can work or look for work, some of the cost may qualify for the Child and Dependent Care Credit. Be sure to keep records and obtain the camp's tax identification information.

Students with summer jobs may be entitled to tax refunds if income tax is withheld from their pay. Adults earning income from seasonal, part-time, or gig work may need additional withholding or quarterly estimated tax payments.

Summer is also a popular wedding season. If you change your name after marriage, update your records with the Social Security Administration. If you move, update your address with the IRS and submit a new Form W-4 to your employer so your withholding reflects your current tax situation.

National 529 Day – Did You Know?

If you put money into a 529 education savings plan, earnings may be withdrawn federal income tax-free when used for qualified education expenses. Qualified expenses can include tuition, fees, books, supplies, computers, and for students enrolled at least half-time, certain room and board costs.

While 529 contributions are not deductible for federal income tax purposes, many states offer a full or partial state income tax deduction or credit for contributions. Some states and plan sponsors may also offer special incentives around National 529 Day.

Recent law changes expanded the use of 529 plans. In 2026, up to $20,000 per year, per student, may be used for qualified K–12 education expenses at public, private, or religious schools. Prior years were generally limited to $10,000 annually.

Qualifying Dependents – Did You Know?

In addition to your children and parents, a number of other individuals may qualify as your dependents for tax purposes. Important factors can include the person's income, how much support you provide, and how much of the year the person lives with you. In some limited cases, even a non-relative who lives with you year round as a member of your household may qualify as a dependent.

Health Savings Accounts - Did You Know?

Changing jobs? If you have a health savings account (HSA), you can take it with you. Unlike flexible spending accounts (FSAs), which are usually tied to your employer, your HSA belongs to you. You can continue using your HSA funds after leaving the job where you opened the account. However, you may make new HSA contributions only if you remain eligible to contribute. To remain eligible, you generally must be covered by an HSA-eligible high-deductible health plan (HDHP) and have no disqualifying coverage.

Receiving Online Payments - Did You Know?

If you are self-employed and receive payments through online payment processing platforms, take care to separate business and personal transactions. You can do this by setting up separate business accounts on the platforms, or by using features that allow you to specify the purpose of payments. Otherwise, the platforms may overreport your income.

Updated Withholding Estimator Available for 2026

Having the right amount of tax withheld from your pay protects you against unpleasant spring surprises, while ensuring that you do not unnecessarily sacrifice take-home pay. The IRS recently made important updates to its Withholding Estimator tool (link below), to account for tax law changes enacted in 2025. Those changes include the "No Tax on Tips" and "No Tax on Overtime" deductions, the car loan interest deduction and special deduction for seniors, and the new deduction rules for charitable donations.

Verifying the accuracy of your withholding a couple of times a year is especially important if you and your spouse both work, or if you owed tax this spring, work multiple jobs, or have self-employment or investment income. It is also a good idea to complete a withholding checkup anytime you experience a major life change like marriage, or the birth or adoption of a child. Using the Withholding Estimator typically takes 25 minutes or less, and you do not have to log in or provide any personally identifying information. If an adjustment to your withholding is needed, the tool can help you complete a new W-4 form to submit to your employer.

IRS Impersonation Scams – Did You Know?

Criminals continue to use IRS impersonation scams to steal money and personal information. Understanding how the IRS actually communicates can help you recognize and avoid these schemes.

The IRS generally initiates contact by sending a letter through the mail on official letterhead. If you have an IRS online account, you can log in to verify whether a notice is legitimate. If you are unsure, you can contact the IRS directly at 800-829-1040.

Scammers, however, often pose as the IRS in several ways:

By mail: Fake letters may look official but include incorrect contact details or suspicious language such as “in relation to your unclaimed refund.”

By email or text: The IRS does not initiate contact this way. Messages promising refunds, credits or urgent fixes often contain links to fraudulent websites designed to steal your information.

By phone: Scammers may leave threatening messages or demand immediate payment using gift cards or other unusual methods—tactics the IRS does not use.

In person: Unannounced visits are extremely rare. Most legitimate IRS appointments are scheduled in advance by letter.

If you suspect a scam, do not respond, click links or share information. Instead, contact the IRS using an official phone number to verify the situation.

IRS Online Business Accounts Now Available to Partnerships & Tax-Exempt Entities

The IRS has expanded its Business Tax Account (BTA) service, which enables businesses to handle many federal tax matters online. Previously, only sole proprietors, S corporations and C corporations could use the BTA platform. Now, partnerships (including LLCs that file taxes as partnerships), along with many tax-exempt organizations, can benefit from the convenience of a BTA as well.

Tasks that can be readily completed through the BTA system include checking tax balances, making payments, viewing payment histories and downloading digital IRS notices. In addition, BTA users can access payroll and income tax return transcripts, seek help with compliance concerns, or verify the accuracy of a business name or address on file with the IRS.

Many government entities, including tribal governments, also qualify to use the expanded BTA service.

Unfiled 2022 Federal Tax Refunds Must Be Claimed by April 15 – Did You Know?

The IRS estimates that over one million people are owed tax refunds from 2022, with the majority of those refunds exceeding $600. However, in order to claim their refunds, people must file their 2022 tax returns by April 15, 2026. Some people may also need to file 2023 and 2024 returns in order to receive an IRS refund.

Those who qualified for the Earned Income Tax Credit (EITC) in 2022 but did not file a return could be missing out on much larger refunds, potentially exceeding $6,000. The adjusted gross income limits for the 2022 EITC ranged from $16,480 to $53,057 (or $22,610 to $59,187 for joint filers), depending on a person's number of qualifying children.

Filing an accurate tax return for 2022 may require referring to income statements like W-2 and 1099 forms. If you cannot locate those forms but have an IRS online account, you can generally obtain the needed information by using the free IRS Get Income Transcript tool (link below). Most people can set up an account in about 20 minutes, less time than it takes to request and receive replacement documents from employers, banks, etc.

IRS Third Party Authorizations – Did You Know?

All U.S. taxpayers have the right to designate a third party to work with the IRS on their behalf. In order to exercise this right, taxpayers must formally grant permission to the third party to represent them. This authorization may take several different forms:

Oral Disclosure: This level of permission simply authorizes the IRS to share the taxpayer's tax information with another person present on a phone call or in a meeting.

Third-party Designee: On their tax returns, taxpayers may designate a third party to discuss the return with the IRS. This authorization is limited to that specific return and year.

Tax Information Authorization: Taxpayers may appoint a third party to receive and review their confidential tax information for a specific type of tax for a designated time period.

Power Of Attorney: This designation authorizes a person or firm to represent the taxpayer in federal tax matters. The person or firm must be certified to practice before the IRS.

Oral disclosure and third-party designee permissions expire automatically. Taxpayers have the right to revoke tax information or power of attorney authorizations at any time, either by notifying the IRS of the revocation, or simply by appointing a new representative.
