US Taxation 2026: Tax credit – How does it work and benefit?

With U S taxation season already on, with the date for filing the tax return already approaching, i.e., April 15, 2026, any tax payer will be interested to know about tax credit which directly helps to subtract an amount of money from the tax one owes as compared the tax deductions which help to reduce the taxable income. A vast difference and a very useful one, indeed.

Learning the rudiments of various types of tax credits does help any tax payer.

How many types of tax credits are available and can we learn them?

There are three categories of tax credits: nonrefundable, refundable, and partially refundable.

Let us learn them.

Nonrefundable Tax Credits

Nonrefundable tax credits indicate that they can be directly deducted from an individual’s tax liability until the tax due reaches $0. Hence, no chance of getting any tax refund, and then it becomes nonrefundable. The remaining part, if any, gets lost.

Nonrefundable tax credits are amounts directly deducted from an individual’s tax liability until the tax due equals $0. Any amount greater than the tax owed, which normally results in a refund for the taxpayer, is not paid out as a refund. Hence the term “nonrefundable.” In effect, the remaining part of a nonrefundable tax credit that can’t be utilized is lost.

They are valid in the year of reporting only, and hence expire after the return is filed and can not be carried over to the future years.

Can we know some of the commonly claimed nonrefundable tax credits?

Yes, here are they.

• Child and Dependent Care Credit: Thishelps working individuals to pay for care of the children under 13 or disabled dependents.
• Lifetime Learning Credit (LLC) which isavailable for qualified tuition and related expenses for undergraduate, graduate, and professional degree courses, and capped at $2,000 per return.
• Saver’s Credit: As the name indicates, it provides a credit for low- to moderate-income taxpayers contributing to retirement accounts (e.g., 401(k) or IRA).
• Foreign Tax Credit: Yes, thisallows taxpayers to offset taxes paid to a foreign government on income that is also taxed in the U.S. In my article on foreign earned income this topic has been covered extensively.
• Adoption Tax Credit:A non-refundable credit to help cover qualified adoption expenses. While learning about adoption, this can be learnt extensively.
• Mortgage Interest Tax Credit: A credit for qualified individuals who hold a mortgage credit certificate to be obtained from the state/local authorities.
• General Business Credit: Comprised of various smaller credits designed to incentivize business activities. These are the credits which are directly subtracted from the total tax bill, providing a more significant incentive for specific activities like R&D, hiring targeted employees, or investing in eco-friendly A complete list can be seen in form 3800.
• Rehabilitation Credit: This credit is related toincentivize the rehabilitation of certified historic buildings.

Now, some information on refundable tax credits.

Refundable tax credits are the most beneficial credit because they’re paid out in full and eagerly looked forward by the middle level or lower middle level tax payers.

This means that a taxpayer (regardless of their income or tax liability) is entitled to the entire amount of the credit, even beyond a zero amount of tax due.

For clarity, if the refundable tax credit reduces the tax liability to below $0, then the taxpayer is due a refund of that full amount.⁵

One of the most popular refundable tax credits is the Earned Income Tax Credit (EITC).

The EITC is for low- to moderate-income taxpayers who earn their income through an employer or by working as a self-employed individual and meet certain criteria based on income and number of family members.

The premium tax credit is also refundable. It helps individuals and families cover the cost of premiums for health insurance purchased through the health insurance marketplace.

The third type of tax credits are partially refundable tax credits.

Yes, some tax credits are partially refundable and one such case is American opportunity tax credit, (AOTC) for post- secondary education students.

If a taxpayer can reduce the tax liability to $0 before using the entire portion of the $2,500 tax deduction, the remainder can be taken as a refundable credit up to the lesser of 40% of the remaining credit or $1,000.

Let me give an example of the tax credit vis a vis tax deduction in a tax case to understand the tax deduction from tax credit.

Comparison of tax credit over tax deduction

You can see that tax credit yielded better figure of taxes owed than tax deductions.

Let me give some tax deductions for recollection.

Standard deduction or itemized deductions, (Schedule A)

US tax deductions reduce your taxable income, with options to take a flat standard deduction or itemize specific expenses.

Common deductions include mortgage interest, charitable donations, state/local taxes (SALT) up to limits, and medical expenses exceeding 7.5% of AGI

Other deductions include student loan interest, IRA/HSA contributions, and business-related expenses.

Some Discussion on Form 3800 – General Business Credit

Form 3800, titled “General Business Credit,” is reproduced below:

https://www.irs.gov/pub/irs-pdf/f3800.pdf

Printed over 9 pages, it broadly consists of the following information:

Part I: Credits Not Allowed Against Tentative Minimum Tax (TMT)

Part II: Figuring Credit Allowed After Limitations

• Section A: Figuring Credit Allowed After Section 38(c)(1) Limitation Based on Amount of Tax
• Section B: Figuring Section 38(c)(2) Empowerment Zone and Renewal Community Employment Credit Allowed
• Section C: Figuring the Specified Credit Amount Allowed Under Section 38(c)(4)
• Section D: Credits Allowed After Limitations

Part III: Current Year General Business Credits (GBCs) (see instructions). If more than one number is applicable for column (b) or (c) for a line in Part III, enter the number of such items in column (a), complete Part V, and refer to the instructions for what to report on that line in Part III.

Part IV: Carryovers of General Business Credits (GBCs)

Observations on Form 3800

It is one of the more complex forms and generally requires the attention of an experienced CPA. The form requires details relating to more than 40 different business credits.

In a nutshell, let me summarize form 3800 for deeper understanding.

• Purpose: To claim general business credits, which are nonrefundable, meaning they can reduce your tax liability to zero, but any excess credit is generally
• How to File: Fill out the specific form for each individual credit, then report the total on Form 3800. Enormous work involved with keen attention and the forms submitted will definitely attract IRS investigative gaze.
• Key Sections:
  • Part I & II: Calculate the allowable credit for the current year.
  • Part III: Lists all individual credits being claimed (e.g., Form 3468, 5884, 6765).
• Carry back/Carry forward: Unused credits can often be carried back one year or forward for 20 years.

If there are any state related FTB 3800 form used for calculating AMT for individuals, estates, and trusts, they need completion as well.

Conclusion.

The amount claimed in tax credits will change after the expiration of the individual income tax provisions of the Tax Cuts and Jobs Act (TCJA) at the end of 2025. According to the Joint Committee on Taxation, under current law, the total costs of the CTC will drop significantly, from nearly $119 billion in tax year 2025 to about $62 billion in tax year 2026.

EITC will gradually increase over the coming years to cost $77 billion in 2026. Those two will remain the largest tax credits.

Hence, any tax credit claimed must be substantiated with enough paper work and information to justify the claims which reduce the tax liability enormously.

Caution

Tax credits is a vast area attracting the best attention of IRS/state authorities and hence need the guidance of an expert CPA/Advocate while the tax returns are prepared. My intention was merely giving the information. It is neither tax guidance/legal advice.
