Refundable v. nonrefundable creditsQuestion: What is the difference between a refundable income tax credit and a nonrefundable income tax credit? Joy Taylor: The federal tax code generally has two types of income tax credits for individuals — refundable credits and nonrefundable credits. Refundable credits allow taxpayers with zero to little income tax liability to benefit from the credit because the credit can exceed the amount of tax liability and result in a refund. A nonrefundable credit can only offset a taxpayer’s tax liability and cannot create a refund. Examples of refundable credits include the American Opportunity tax credit, the earned income credit and the health premium tax credit. Examples of nonrefundable credits include the credit for child and dependent care expenses taken by working parents, the foreign tax credit and the now-expired tax credits for buying electric vehicles and installing eco-friendly improvements in your primary residence.2. Expired electric vehicle creditQuestion: I bought a used Tesla earlier this year for personal use. Can I claim a federal income tax credit on my 2026 Form 1040 for this purchase? Joy Taylor: No. Unfortunately, the clean-vehicle credit for buying a new or used electric vehicle (EV) has expired. The up-to-$7,500 credit for buying new EVs and the up-to-$4,000 credit for buying used EVs ended after September 30, 2025. So you can’t claim a credit for your 2026 used EV purchase. Congress chose to eliminate this credit in the “One Big Beautiful Bill” legislation that it enacted in July 2025. 3. Adoption creditQuestion: I have clients who adopted a baby last year. I am now filling out their 2025 Form 1040, which they received a filing extension for, and I see that part of the adoption tax credit is now refundable. When was this change enacted?Joy Taylor: The adoption tax credit can be taken on up to $17,670 of qualified expenses per eligible child in 2026. The 2025 amount was $17,280. Qualified expenses include adoption fees, court costs, legal expenses, travel, meals and other expenses directly related to a legal adoption. The full credit is available for the adoption of a special-needs child, even if it costs less. The credit starts phasing out for filers with 2026 modified adjusted gross incomes (AGI) over $265,080 and ends at $305,080. The 2025 figures are $259,190 and $299,190. The credit amount and the modified AGI amounts are adjusted annually to account for inflation. Parents claim the adoption credit on IRS Form 8839. Up to $5,120 of the adoption credit is fully refundable in 2026. This new rule, which was included in the “One Big Beautiful Bill,” gives adopting parents $5,120 of the credit as a refund, even if they have no income tax liability. The refundable amount is adjusted annually to account for inflation. It was $5,000 for 2025 tax returns. (The remaining portion of the credit is a nonrefundable tax credit that can be carried forward for five years).4. Dependent care creditQuestion: I work and also take care of my elderly father. I pay for his care when I am at work. Can I take the dependent care credit for him?Joy Taylor: To claim the dependent care credit for your dad, he needs to have lived with you for at least six months during the year and be unable to care for himself. Additionally, you must provide over half of his support. Other rules for the dependent credit must also be met. For example, expenses for the care must be incurred so you can work, and you must report the provider’s tax ID number on IRS Form 2441.If your dad qualifies as a dependent for this purpose, you can claim a maximum dependent care credit of $1,500 for him on your 2026 Form 1040 that you file next year, depending on the amount of your income.
