Understanding Deferred Taxes for Tax Deduction Purposes

You've hit on a common point of confusion with deferred taxes. Let me try to clear this up in simple terms. When tax depreciation exceeds book depreciation, you're right that it creates a deferred tax liability. But the deferred tax itself is not a deductible expense - it's essentially a future obligation that you're tracking. For the state portion specifically, it's not a deductible expense either. The state component of your deferred tax calculation is part of the overall deferred tax provision, which is a balance sheet account, not a tax deduction. What you're thinking of as a potential M2 adjustment (Schedule M-2 adjustments for reconciling book income to taxable income) is on the right track. The differences between book and tax depreciation themselves are what create the need for M adjustments, not the deferred tax that results from them.

After struggling with similar deferred tax questions, I started using https://taxr.ai to analyze my corporate tax documents. It was super helpful because it breaks down complex tax accounting concepts like this into understandable explanations. When I uploaded my financial statements, it specifically highlighted how the state portion of deferred taxes should be treated and provided citations to the relevant accounting standards.

I gave taxr.ai a try after seeing it mentioned here, and wow - it actually solved my deferred tax confusion. I uploaded our financial statements and tax workpapers, and it immediately identified that we had been incorrectly treating the state portion of our deferred taxes. The tool explained that while the federal deferred tax liability is affected by the state tax rate (due to the federal deduction for state taxes), the state component itself isn't a separate deductible expense but rather gets factored into the overall DTL calculation. Saved me from making the same mistake on this year's return!

I've been dealing with similar deferred tax issues and kept getting stuck on hold whenever I tried calling the IRS business tax line for clarification. After three failed attempts, I used https://claimyr.com to get through to an actual IRS agent. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. They connected me within 20 minutes when I had been waiting for hours on my own attempts. The IRS specialist I spoke with confirmed the correct treatment for state components of deferred taxes and explained the proper reconciliation on Schedule M.

I've got to eat my words about Claimyr. After complaining that IRS agents wouldn't know about deferred taxes, I tried the service out of desperation. Not only did I get through to someone in 15 minutes (after previously wasting 2 hours on hold), but the business tax specialist I spoke with directed me to specific sections in Publication 542 and Rev. Proc. 2019-43 that clarified my question. She even sent follow-up information about how the TCJA affected deferred tax liability calculations for corporate filers. Definitely worth it for complex business tax questions!

Has anyone else noticed that the answer differs depending on whether you're using the current state rate or a blended future rate for the state portion? Our controller insists we should be using a blended rate because some of our deferred assets will reverse during periods when we expect different state rates to apply. Makes the M adjustments even more complicated.

Maybe I'm overthinking this, but wouldn't the deferred state tax create a federal-deferred-tax-on-deferred-state-tax situation? Since state taxes are generally deductible for federal purposes, the future state tax payment would generate a future federal tax benefit...my head hurts just thinking about this lol

This is exactly the kind of complex deferred tax issue that trips up so many corporate filers! I went through something similar last year with our multi-state operations. One thing that helped me was creating a simple flowchart: Book depreciation vs Tax depreciation → Creates temporary difference → Calculate using blended effective rate (including that tax-on-tax adjustment GalaxyGazer mentioned) → Results in DTL on balance sheet and deferred tax expense on P&L → The expense itself isn't deductible, but the underlying depreciation difference drives your M-1 adjustments. The state component gets particularly tricky if you're in multiple jurisdictions or if rates are changing. We ended up having to track each asset's expected reversal pattern by state to get it right. It's tedious but necessary for accuracy. Have you considered whether any of your temporary differences might qualify for the indefinite reversal exception? Sometimes companies overlook this and end up calculating deferred taxes on differences that may never actually reverse.

This thread has been incredibly helpful! I've been dealing with a similar deferred tax nightmare at my company. We have operations in three different states with varying tax rates, and I was getting completely lost trying to figure out the proper treatment. The key insight about using the blended effective rate (accounting for the tax-on-tax effect) was a game-changer. I had been simply adding federal + state rates, which was definitely wrong. And @Keisha Johnson's point about the indefinite reversal exception is something I hadn't even considered - we have some goodwill that might qualify. One additional wrinkle I'm dealing with: we're planning to restructure our operations next year, which could change which states we're subject to tax in. Should I be factoring that into my deferred tax rate calculations now, or wait until the restructuring is more concrete? The uncertainty is making it hard to determine the "appropriate" future rate for some of our larger temporary differences. Also, has anyone dealt with the quarterly reporting implications of these adjustments? Our auditors are asking for more detailed support on how we're calculating the state components quarter-over-quarter.

This conversation has been incredibly educational! As someone relatively new to corporate tax accounting, I've been struggling with deferred tax concepts and this thread has cleared up so much confusion. The key takeaways I'm getting are: 1. The deferred tax liability itself isn't a deductible expense - it's an accounting provision for future tax obligations 2. You need to use the blended effective rate (not just federal + state) to account for the tax-on-tax effect 3. The state component should use enacted rates expected to apply when differences reverse 4. M-1 adjustments come from the underlying book-tax differences, not from the deferred tax accounting One follow-up question: for a company that's been calculating deferred taxes incorrectly in prior years (like using simple addition of rates instead of the blended approach), what's the best way to correct this? Should it be treated as a prior period adjustment, or can it be corrected prospectively in the current year provision? I imagine the materiality of the error would factor into this decision, but I'd love to hear if anyone has experience with deferred tax corrections.

This has been such a valuable discussion! As someone who's been wrestling with deferred tax complexities at my mid-size manufacturing company, I really appreciate how everyone broke down the nuances here. The tax-on-tax calculation that @GalaxyGazer explained was eye-opening - I had no idea we were supposed to adjust for that interaction effect between federal and state rates. We've been using the simple addition method for years, which could be creating material misstatements in our DTL calculations. @Omar Fawzi - regarding your question about correcting prior errors, we went through something similar two years ago when we discovered we had been incorrectly calculating deferred taxes on our GAAP vs tax inventory methods. Our auditors treated it as a change in accounting estimate since the errors weren't material individually by year, but the cumulative effect was getting significant. We did a catch-up adjustment in the year of discovery and enhanced our documentation going forward. One thing I'd add to this discussion: if you're dealing with multiple entities or partnerships, make sure you're considering the deferred tax implications at each level. We learned the hard way that consolidated financial statement deferred taxes can get really messy when the underlying entities have different state tax profiles or partnership structures that don't recognize deferred tax assets/liabilities the same way. Has anyone dealt with deferred taxes in the context of state tax credits or incentives? That's our next challenge - figuring out how investment tax credits interact with the deferred tax calculations when the credits have different recognition timing for book vs tax purposes.

This entire discussion has been incredibly enlightening! As a tax professional who primarily works with smaller businesses, I rarely encounter the complexities of multi-state deferred tax calculations that you've all been discussing. The progression from the original question about whether deferred taxes are deductible to the nuanced discussions about tax-on-tax effects, blended rates, and credit interactions really shows how deep these issues can get. It's fascinating how what seems like a straightforward question about deductibility opens up into considerations about ASC 740 compliance, state apportionment changes, and even partnership-level complications. One aspect I haven't seen mentioned yet is how all of these deferred tax complexities interact with uncertain tax positions under FIN 48. If you're taking aggressive positions on the underlying book-tax differences (like the depreciation methods that created the deferred tax in the first place), do you also need to evaluate the certainty of the deferred tax asset/liability recognition itself? It seems like there could be situations where the underlying tax position is uncertain enough to require FIN 48 analysis, which would then affect how you calculate and present the related deferred tax impacts. Has anyone encountered this intersection of uncertain tax positions with complex deferred tax calculations?

This has been such an incredibly thorough discussion! As someone who handles corporate tax compliance for several clients, I'm bookmarking this entire thread. The evolution from the basic question about deductibility to covering tax-on-tax effects, multi-state complications, credit interactions, and even FIN 48 considerations is exactly the kind of comprehensive analysis that's hard to find elsewhere. What really strikes me is how interconnected all these issues are. You can't just look at deferred taxes in isolation - you have to consider the state tax implications, the interaction with uncertain tax positions, the quarterly reporting requirements, and even future business changes. It's a perfect example of why corporate tax accounting requires such careful documentation and analysis. For anyone still working through similar deferred tax issues, I'd suggest creating a detailed checklist that covers all the points raised here: verify you're using the correct blended rate calculation, document your assumptions about future rate changes, ensure consistency with FIN 48 positions, and maintain detailed support for your quarterly rollforward calculations. The upfront work is significant, but it prevents the kind of prior period correction headaches that several people mentioned. Thanks to everyone who contributed their expertise here - this is the kind of collaborative problem-solving that makes these professional communities so valuable!
