2025 FTB Update: Calculating Your Minimum Tax Credit Just Got Easier
Hello there, fellow taxpayers and tax professionals! Let’s be real—tax season is rarely anyone’s favorite time of the year. If you’re based in California or doing business here, you already know that keeping up with the Franchise Tax Board (FTB) rules can feel like trying to hit a moving target while blindfolded. I’ve been there, staring at a stack of forms, wondering if I missed a tiny update that could change my entire filing. 😅
Well, I have some news that might actually make your life a little bit easier this year. On February 12, 2026, the FTB released a Tax News Flash detailing some very specific, but highly impactful, updates to the form instructions for the 2025 taxable year. These changes directly relate to the computation of the credit for the prior year alternative minimum tax, which most of us simply call the “minimum tax credit.”
If you or your corporate entity have historically dealt with AMT and solar energy credit carryovers, you’ll definitely want to pay attention. We are going to break down exactly what was deleted, what it means for your tax prep, and how to calculate your credit moving forward. Take a deep breath, grab your favorite caffeinated beverage, and let’s dive into the world of California tax updates! ☕
Understanding the Basics: What is the AMT? 🤔
Before we jump into the nitty-gritty of the 2025 updates, let’s take a moment to review what the Alternative Minimum Tax (AMT) actually is. I know, it’s a technical term, but I promise to keep it simple!
In essence, the tax code is full of deductions, credits, and loopholes. The AMT is a parallel tax system designed to ensure that individuals and corporations who benefit from these various tax preferences still pay a baseline level of tax. If your calculated regular tax is lower than your calculated AMT, you end up having to pay the AMT amount instead. It can be super frustrating, but it’s the state’s way of leveling the playing field.
Not all tax preferences are treated equally under the AMT rules. There are two main types: exclusion preferences (which permanently avoid tax) and deferral preferences (which simply delay when you pay the tax). The minimum tax credit we are discussing today is generally generated from those deferral preferences!
When you pay AMT in one year due to these deferral preferences, you essentially generate a “credit” that you can use in future years when your regular tax is higher than your AMT. This is the Credit for Prior Year Alternative Minimum Tax. It’s a way for the FTB to say, “Okay, you paid extra tax early, so we’ll give you a discount later.”
The Big Change: What Did the FTB Delete for 2025? ✂️
Now, let’s get to the meat of the February 12, 2026 update. Historically, calculating your minimum tax credit involved some complex subtraction. The FTB updated the instructions for Schedule P (100), Schedule P (100W), and Form FTB 3510 for the 2025 taxable year by removing specific sentences that previously forced taxpayers to reduce their prior year AMT by certain credits.
Prior to this update, the line instructions required you to reduce your prior year AMT with the credits you used to lower that prior year AMT. For example, if you used a solar energy credit carryover to lower your 2024 AMT, the old rules said you had to subtract that amount when calculating your credit for 2025. This caused a lot of headaches and double-checking of old tax returns!
The amazing news? The updated form instructions no longer require that reduction. The FTB has literally deleted the sentences mandating this extra math.
Even though the calculation is simpler, you still need to have your accurate 2024 AMT forms on hand to pull the correct baseline numbers. Do not throw away last year’s Schedule P!
A Closer Look at the Affected Forms 📊
To ensure you know exactly where to look on your tax paperwork, I’ve broken down the exact forms and the specific instructions that were removed. This is where things get a bit technical, but having this cheat sheet will save you tons of time.
| Form Name | Line Affected | What Was Deleted? |
|---|---|---|
| Schedule P (100) Corporate | Part III, Line 1 | “If this amount was reduced by any credits from Part II, Section C, use the AMT from the 2024 Schedule P (100), Section C, line 18.” |
| Schedule P (100W) Water’s-Edge Corporate | Part III, Line 1 | “If this amount was reduced by any credits from Part II, Section C, use the AMT from the 2024 Schedule P (100W), Section C, line 18.” |
| Form FTB 3510 Individuals/Fiduciaries | Line 28 | The instruction to reduce Line 28 if the 2024 AMT was reduced by a solar energy credit carryover (referencing Schedule P forms 540, 540NR, 541). |
By deleting these sentences, the FTB is standardizing the process. Whether you are a large corporation filing a 100W or an individual dealing with FTB 3510, you no longer have to factor in those specific credit reductions from the prior year’s AMT.
How to Calculate the Credit Now: A Practical Example 🧮
So, what does this actually look like when you sit down with your accountant or your tax software? With the update, the computation is incredibly straightforward.
For corporate taxpayers, you compute your minimum tax credit simply by taking your prior year AMT and adding your prior year unused allowable minimum tax credit carryover. Individual and fiduciary taxpayers generally do the same thing (to the extent the amount of AMT was attributable to deferral preferences).
📝 The Simplified Formula for 2025
Minimum Tax Credit = (Prior Year AMT) + (Prior Year Unused Allowable Minimum Tax Credit Carryover)
Let’s look at a hypothetical case study to see this in action.
Case Study: Solar Solutions Corp.
- 2024 Unadjusted AMT: $10,000
- 2024 Solar Energy Credit Used: $2,000
- Prior Year Unused Allowable Minimum Tax Credit Carryover: $5,000
Calculation Process
The Old Way (Before 2025): You would have to take the $10,000 AMT, subtract the $2,000 solar credit (leaving $8,000), and then add the $5,000 carryover. It was an extra step that caused confusion.
The New Way (2025 onwards): You simply take your Prior Year AMT and add your unused carryovers without worrying about the solar credit reduction subtraction.
Final Result
– The calculation is more streamlined and less prone to manual data entry errors.
– Taxpayers can calculate their available credit faster and with more confidence.
To be honest, any time a taxing authority removes a step instead of adding one, it’s a win in my book. It reduces the chance of making a mistake that could trigger an audit or a delayed refund.

Important Considerations for YMYL (Your Money or Your Life) 👩💼👨💻
Because we are talking about taxes, we are deep into “Your Money or Your Life” territory. While the removal of these specific reduction sentences simplifies the base calculation, the tax code is inherently complex. The way individuals compute the minimum tax credit still hinges heavily on “deferral preferences.”
If you are an individual taxpayer filing FTB 3510, you can only use this credit to the extent that your prior year AMT was caused by items that just delayed your tax burden (like accelerated depreciation) rather than completely excluded income (like certain tax-exempt interest). Figuring out that exact ratio often requires sophisticated tax software or the keen eye of a CPA.

Because every individual’s and corporation’s tax situation is completely unique, please consult with a certified tax professional or CPA before finalizing and submitting your 2025 tax returns.

Tax law is constantly evolving, and keeping up with the FTB’s updates is crucial for filing accurate returns. The removal of the reduction requirements on Schedule P and Form 3510 might seem like a minor administrative tweak, but for those calculating the minimum tax credit, it removes a layer of complexity that has frustrated many in the past.
By simply adding your prior year AMT and your unused allowable minimum tax credit carryover, the 2025 taxable year forms promise a smoother calculation experience.
