Noon: Individual Tax Tips & Refund Strategies : September Moves for Families & Self-Employed Filers

New Haven, Connecticut : Jose’s Tax Service : September 1, 2026

September is an important tax-planning month. Families are adjusting to the school year. Self-employed taxpayers are approaching the third federal and Connecticut estimated-tax deadlines. Health Savings Account (HSA) contribution planning should also be reviewed before year-end.

These steps can improve your tax refund, reduce surprises, and support better personal finance decisions. They should be completed with current income, household, and benefit information.

Review Family Tax Benefits Now!

Back-to-school season is a practical time to review dependents, childcare arrangements, education payments, and payroll withholding. Do not assume that every school-related expense qualifies for a federal credit. Eligibility depends on the specific expense and the taxpayer’s facts.

Complete these September actions:

1. Confirm every dependent.

   • Verify each child’s legal name, date of birth, and Social Security number (SSN).
   • Confirm that the child meets the residency, support, age, and dependent requirements.
   • Review custody arrangements if parents are divorced, separated, or living apart.

2. Separate qualifying credits from ordinary school expenses.

   • Ordinary K–12 school supplies, uniforms, tuition, and activity fees generally do not automatically qualify for a federal individual education credit.
   • Postsecondary tuition and related expenses may qualify for the American Opportunity Tax Credit (AOTC) or Lifetime Learning Credit (LLC), subject to eligibility rules.
   • Keep Forms 1098-T, Tuition Statement, receipts, and enrollment records for college or career-training expenses.

3. Review childcare payments.

   • A child under age 13 may be a qualifying person for the federal Child and Dependent Care Credit.
   • Care generally must allow you, and your spouse if filing jointly, to work or actively look for work.
   • Record the provider’s name, address, and employer identification number (EIN) or Social Security number (SSN).

A careful review now can prevent missing information when Form 1040, U.S. Individual Income Tax Return, is prepared.

Confirm the 2026 Child Tax Credit!

The Child Tax Credit (CTC) may be worth up to $2,200 per qualifying child for tax year 2026. The Additional Child Tax Credit (ACTC) may provide a refundable amount of up to $1,700 per qualifying child, depending on income and other requirements.

The credit is generally available for a qualifying child who:

• Is under age 17 at the end of 2026.
• Is claimed as your dependent.
• Has lived with you for more than half of the year, subject to special rules.
• Has not provided more than half of their own support.
• Is a U.S. citizen, U.S. national, or U.S. resident alien.
• Has a valid SSN issued before the due date of the return, including extensions.

The full credit generally applies when modified adjusted gross income (MAGI) does not exceed $200,000, or $400,000 for married taxpayers filing jointly. The credit may be reduced above those thresholds.

Use the following checklist:

1. Enter all qualifying children correctly on your year-end tax organizer.
2. Verify SSNs against Social Security cards.
3. Review income changes, bonuses, investment income, and self-employment income.
4. Use the IRS Child Tax Credit information page and the Interactive Tax Assistant.
5. Claim the credit on Form 1040 and complete Schedule 8812, Credits for Qualifying Children and Other Dependents, when required.

Incorrect dependent information can delay processing or lead to a denied credit. Keep supporting records with your tax file.

Coordinate the Dependent Care FSA and Childcare Credit!

A Dependent Care Flexible Spending Arrangement (FSA) can allow employees to pay eligible dependent-care expenses with pre-tax payroll deductions. The precise contribution limit, carryover provision, grace period, and reimbursement rules are controlled by the employer’s plan.

Do not treat the Dependent Care FSA and the Child and Dependent Care Credit as separate benefits without coordinating them. Expenses reimbursed through tax-free FSA dollars generally cannot also be used to claim the full federal credit.

In September, complete these steps:

1. Request your year-to-date FSA balance.
2. Compare the balance with expected fall and winter care costs.
3. Review your employer’s deadline for submitting claims.
4. Confirm whether the plan provides a carryover or grace period.
5. Retain provider statements and payment records.
6. Separate FSA-reimbursed expenses from expenses being considered for Form 2441.

The Child and Dependent Care Credit is claimed using Form 2441, Child and Dependent Care Expenses, attached to Form 1040. You must identify the care provider unless an exception applies.

Read the IRS Child and Dependent Care Credit information, Publication 503, Child and Dependent Care Expenses, and Form 2441 before finalizing the calculation.

Reminder: Review your employer’s plan documents before changing an election. Mid-year changes may be restricted to qualifying events.

Use September to Adjust Your HSA Strategy!

For calendar year 2026, the HSA contribution limits are:

• Self-only coverage: $4,400.
• Family coverage: $8,750.
• Catch-up contribution for eligible individuals age 55 or older: an additional $1,000.

These limits include contributions from all sources, including employee payroll deductions, employer contributions, and direct contributions. An individual who is age 55 or older must generally make the catch-up contribution to that individual’s separate HSA. Medicare enrollment can eliminate eligibility to contribute beginning with the applicable month.

An HSA generally requires coverage under an eligible high-deductible health plan (HDHP). Other coverage, a general-purpose health FSA, or Medicare enrollment may affect eligibility.

Complete the following review:

1. Obtain your year-to-date HSA contribution total.
2. Include employer contributions in the calculation.
3. Compare contributions with the applicable $4,400 or $8,750 limit.
4. Add the $1,000 catch-up amount only when the eligibility requirements are met.
5. Adjust payroll deductions before December if you intend to reach the annual limit.
6. Keep receipts for qualified medical expenses.
7. Confirm that reimbursements are not duplicated through another health plan or tax deduction.

HSA activity is generally reported on Form 8889, Health Savings Accounts (HSAs), filed with Form 1040. Excess contributions may be nondeductible and may lead to a 6% excise tax if not corrected.

See IRS Publication 969, Health Savings Accounts and Other Tax-Favored Health Plans and Revenue Procedure 2025-19 for additional guidance.

Pay Q3 Estimated Taxes by September 15, 2026!

Self-employed taxpayers should review the third-quarter estimated-tax payment immediately. For calendar-year individuals, the federal Q3 estimated tax payment is due September 15, 2026.

Use Form 1040-ES, Estimated Tax for Individuals, to calculate and pay federal estimated tax. Estimated tax may apply to income not subject to sufficient withholding, including:

• Freelance or consulting income.
• Gig-economy payments.
• Schedule C business income.
• Rental income.
• Interest, dividends, and capital gains.
• Taxable retirement or unemployment income without adequate withholding.

Use the current 2026 Form 1040-ES. Payments may be made electronically through IRS Direct Pay or another approved IRS payment method.

Connecticut residents and taxpayers with Connecticut-source income should also review Form CT-1040ES, Estimated Connecticut Income Tax Payment Coupon for Individuals. The third Connecticut installment is due September 15, 2026. The installment is generally 25% of the required annual payment, bringing cumulative payments to 75% by that date.

Review the Connecticut Department of Revenue Services individual income tax information and the applicable 2026 CT-1040ES instructions before submitting payment.

A missed or insufficient payment may lead to interest or an underpayment penalty. A tax professional should review taxpayers with uneven income, large gains, significant business changes, or prior-year tax complications.

Use the IRS Tax Withholding Estimator and Publication 505!

Employees with W-2 income should not overlook withholding. A household may have sufficient total income but insufficient federal withholding because both spouses work, a bonus was paid, a second job began, or business income was added.

Use the IRS Tax Withholding Estimator with:

• Recent paystubs.
• Spouse’s paystubs, when filing jointly.
• Your most recent federal tax return.
• Expected self-employment or investment income.
• Anticipated credits and deductions.
• Year-to-date federal and state withholding.

The estimator can generate a completed Form W-4, Employee’s Withholding Certificate. Submit the updated form to your employer when additional withholding is required.

For complex situations, review Publication 505, Tax Withholding and Estimated Tax. Publication 505 explains the pay-as-you-go system, withholding, estimated payments, and safe-harbor concepts.

Use the results to decide whether you should:

1. Increase payroll withholding.
2. Make or adjust the September 15 estimated payment.
3. Revise fourth-quarter business income projections.
4. Set aside funds for federal and Connecticut tax.
5. Schedule a year-end tax-planning consultation.
