Most taxpayers do not overpay because they want to. They overpay because they do not know which credits apply, what documentation is required, or which credits quietly expired before they had a chance to claim them.
Before we get into the list, one distinction worth clarifying — because it changes how you should prioritize your filing review.
You have probably heard the words tax deduction and tax credit used interchangeably. They are not the same thing.
- Reduces your taxable income
- A $1,000 deduction saves you $220 (22% bracket)
- Value depends on your tax bracket
- Reduces your actual tax bill
- A $1,000 credit saves you exactly $1,000
- Dollar-for-dollar — no bracket math
That is why credits are so valuable. And that is why missing them is so costly. Most tax credits do not require complicated financial moves to qualify for. Many individuals and business owners are already eligible for credits they have never claimed — simply because no one told them about them.
Tax credits have eligibility requirements, income limits, and rules that change annually. This article is for general education only and reflects 2026 tax law to the best of our knowledge. Before claiming any credit on your return, speak with a licensed CPA who can review your specific situation.
Some credits increased. Some expired. Some apply only if specific timing rules were met. Before relying on last year's tax strategy, confirm whether the credit still applies for 2026.

📋 What's In This Guide
- 1. Child Tax Credit
- 2. Child & Dependent Care Credit
- 3. Earned Income Tax Credit (EITC)
- 4. American Opportunity & Lifetime Learning Credits
- 5. Electric Vehicle Tax Credits
- 6. Home Energy Efficiency Credits
For 2026, the Child Tax Credit may be worth up to $2,200 per qualifying child, with up to $1,700 potentially refundable through the Additional Child Tax Credit. The credit begins to phase out once modified AGI exceeds $200,000 for most filers or $400,000 for married couples filing jointly — but it phases out gradually rather than disappearing at those thresholds.
Basic Requirements
- Child must be under 17 at the end of the tax year
- Child must live with you for more than half the year
- Child must have a valid SSN issued before the return due date (including extensions)
- The taxpayer — or at least one spouse on a joint return — must also have a valid SSN issued before the return due date
- Your modified AGI must not exceed the phase-out thresholds above
Common mistake: Many parents assume this credit is applied automatically. It is not. It must be specifically claimed and documented. If your preparer is not asking for your dependents' Social Security numbers and birth dates, that is a problem.
Child's SSN, date of birth, months lived with you during the year, custody documentation if applicable, and prior-year dependent claim history if there is any question about who can claim the child.
This credit is different from the Child Tax Credit — and it is one of the most commonly missed credits we see on new client returns. If you pay someone to care for a child under 13 or a disabled dependent so you can work, a portion of those expenses comes back to you as a credit.
What Qualifies
- Licensed daycare and childcare centers
- In-home nannies or babysitters
- After-school care programs
- Day camps (not overnight camps)
- Care for a disabled dependent of any age
The name, address, and Tax ID number of the care provider. Without this information, the credit cannot be claimed — no exceptions. If your employer offers a Dependent Care FSA, you can still claim this credit on expenses not already covered by the FSA.
The Earned Income Tax Credit is one of the largest refundable credits in the tax code — and one of the most frequently unclaimed. For 2026, the maximum EITC is $8,231 for eligible taxpayers with three or more qualifying children. The exact amount depends on your filing status and number of qualifying children and should be calculated using the official 2026 IRS tables.
2026 Income Limits
| Situation | Single Filer Limit | Married Filing Jointly |
|---|---|---|
| No children | ~$19,100 | ~$26,200 |
| 1 qualifying child | ~$50,400 | ~$57,500 |
| 2 qualifying children | ~$56,700 | ~$63,800 |
| 3+ qualifying children | ~$60,900 | ~$68,000 |
Income limits above reflect 2026 IRS inflation-adjusted figures. Confirm exact thresholds using the official 2026 IRS revenue procedure or with your CPA.
Why business owners miss it: A year with lower net self-employment income may qualify you — but many self-employed filers never think to check. Also note: if your investment income exceeds ~$11,950 in 2026, you do not qualify regardless of earned income.
W-2s, 1099s, Schedule C profit/loss, investment income statements (to verify the investment income limit), Social Security numbers for all qualifying children, and documentation of residency for any children claimed.
Two separate education credits exist — and they are frequently confused. Here is a clear side-by-side comparison for 2026.
Which One Should You Claim?
- AOTC — First four years of college only. More valuable if your student qualifies. Phases out $80,000–$90,000 (single) / $160,000–$180,000 (married)
- LLC — No year limit. Graduate school, professional development, part-time courses all qualify. Same income phase-out range as AOTC
You cannot claim both credits for the same student in the same year. A CPA will run the numbers both ways and determine which produces the better result for your situation.
Important update for 2026: The federal clean vehicle credits generally ended for vehicles acquired after September 30, 2025. If you purchased an EV in 2026, the federal credit is most likely not available to you under current law.
This is one of the most significant credit changes for the 2026 filing year. The new clean vehicle credit (IRC §30D) and the used clean vehicle credit (IRC §25E) were not extended beyond the September 30, 2025 acquisition deadline under current legislation.
Limited Transition Rules May Still Apply If:
New EV Requirements
- Vehicle must be assembled in North America
- Battery component sourcing requirements must be met
- MSRP cap: $80,000 for SUVs and trucks / $55,000 for all other vehicles
- Your income must fall below the limits above
Used EV Requirements
- Vehicle must be at least two model years old
- Purchase price must be $25,000 or less
- Lower income limits apply: $75,000 (single) / $150,000 (married)
Common mistake: Many buyers assume they qualify and proceed with the purchase — then learn after the fact that their income was over the limit or the vehicle did not meet the assembly requirement. Always verify eligibility before purchase, not after.
Important update for 2026: Under current IRS guidance, both the Energy Efficient Home Improvement Credit (§25C) and the Residential Clean Energy Credit (§25D) are generally not allowed for property placed in service or expenditures made after December 31, 2025.
What This Means for Your Filing
If you made home energy improvements or installed solar or clean energy systems in 2025, you may still be able to claim these credits when filing your 2025 tax return. These credits do not carry forward as a new 2026 benefit for work completed in 2026 under current law.
- Not available for property placed in service after 12/31/2025
- May still apply on your 2025 return
- Covered: heat pumps, insulation, windows, doors
- Not available for expenditures made after 12/31/2025
- May still apply on your 2025 return
- Covered: solar panels, geothermal, battery storage
If you installed qualifying energy improvements or clean energy systems in 2025, bring your receipts, contractor invoices, and product certifications to your CPA. These credits can be substantial and require proper documentation to claim correctly.
The R&D Tax Credit is not just for pharmaceutical companies or tech giants. It applies to a surprisingly wide range of small and mid-sized businesses — and most owners do not know they qualify.
Plain-English version: If your business spends time and money trying to figure out how to build, improve, or create something — and there is genuine uncertainty about whether it will work — you may qualify.
Who Commonly Qualifies
- Software companies building custom applications or platforms
- Engineering firms working on new designs or processes
- Manufacturing companies improving production methods
- Food and beverage businesses developing new formulations
- Construction firms using innovative building techniques
- Agricultural businesses working on new growing methods
Businesses with less than $5 million in gross receipts and fewer than five years of revenue can apply the R&D credit against payroll taxes — making it usable even before the business is profitable. This is one of the most underused provisions for early-stage companies.
Documentation is non-negotiable: The IRS scrutinizes R&D credits carefully. You need employee time logs, project descriptions, supply invoices, and evidence of experimentation. If you think you might qualify, start documenting now — retroactive records are much harder to defend.
Payroll records showing time on qualifying projects, project notes and technical descriptions, invoices for qualifying supplies, contractor agreements, testing records, and any prototype or development logs. The documentation should establish technological uncertainty and the process of experimentation.
Important update for 2026: As of current guidance, WOTC generally applies only to qualifying employees who began work on or before December 31, 2025. The Department of Labor confirmed in April 2026 that Congress had not extended WOTC authority for new hires beginning work after that date. Do not assume WOTC is available for employees hired in 2026.
WOTC May Still Apply If:
- The employee began work on or before December 31, 2025
- IRS Form 8850 was submitted to your state workforce agency within 28 days of the employee's start date
- The employee belongs to a qualifying target group
- You have the required certification from the state workforce agency
WOTC has been extended multiple times in the past. Employers should monitor whether Congress extends the credit for 2026 hires. If extended, you will want the Form 8850 process built into your onboarding before any new hire begins — because the 28-day deadline starts on day one and cannot be extended retroactively.
If you own a small business and pay for your employees' health insurance, you may be able to claim a credit worth up to 50% of the premiums you pay (35% for tax-exempt organizations).
To Qualify
- Fewer than 25 full-time equivalent employees
- Average employee wage below the annual inflation-adjusted threshold (~$64,000 for 2026)
- You pay at least 50% of each employee's premium for employee-only coverage
- Coverage must be purchased through the SHOP Marketplace (or a limited exception applies)
First, the 50% credit is the maximum — the actual credit phases down based on your number of FTEs and average wages. Second, this credit is only available for two consecutive taxable years. After that, you cannot claim it again even if you still meet the eligibility requirements. Plan accordingly.
If your business spends money to improve accessibility for customers or employees with disabilities — ramps, accessible restrooms, sign language interpreters, Braille materials — you may qualify for this credit.
What Qualifies
- Installing ramps and accessible entrances
- Adding accessible parking spaces
- Providing sign language interpreters or Braille materials
- Visual alarms for hearing-impaired individuals
- Purchasing adaptive equipment for employees
Three Things That Trip People Up Every Year
1. Refundable vs. Non-Refundable
Not all credits work the same way. Some reduce your bill to zero and then pay you the rest as a refund. Others can only bring your bill to zero — nothing more. Here is a quick reference:
2. Documentation Is Not Optional
Every credit on this list has specific documentation requirements. Childcare provider Tax IDs, IRS Form 8850 for WOTC, time logs for R&D, VIN numbers for EV credits. Missing documentation is the most common reason credits are denied on audit — even when the taxpayer legitimately qualified.
3. Credits Change — Sometimes Every Year
Tax credits are created, modified, extended, and expired by Congress on a regular basis. The credits in this article reflect 2026 tax law to the best of our knowledge — but details shift. A licensed CPA stays current so you do not have to.
Tax credits are the most direct mechanism in the tax code for reducing what you actually owe — dollar for dollar. And yet they are consistently missed by individuals filing on their own and by businesses using software that asks the right questions but does not know their situation.
A CPA-prepared return is not just more accurate. It is more complete. Identifying and correctly documenting applicable credits is part of what professional tax preparation actually means — and it is one of the clearest ways a licensed CPA earns the fee.
If you are unsure whether any of the credits above apply to your 2026 return, that question is worth a conversation.
Not Sure Which Credits Apply to You?
A missed credit can cost far more than the price of professional tax preparation. Pocket CPA reviews your return for applicable credits, documentation gaps, and filing accuracy — so you are not relying on guesswork.
