That $500K you prepaid for Reserved Instances? If you deducted it all in year one, the IRS is going to have questions. Learn why your GPU costs might qualify for R&D credits you're not claiming and how to avoid expensive accounting mistakes that surface during fundraising.

When you're burning through thousands of dollars monthly on AWS, Google Cloud, or Azure GPU instances to train your latest model, the last thing on your mind is probably tax accounting. But here's the reality: how you categorize these expenses can significantly impact your cash flow, financial statements, and even your ability to secure funding.
AI developers face a unique accounting challenge; traditional software companies don't typically rack up $50,000 monthly compute bills. The rules weren't written with your H100 rentals in mind. Let's break down exactly how to handle GPU compute costs for tax and accounting purposes.
The Basic Rule: Most GPU Costs Are Operating Expenses
When you rent cloud GPU services, you're not buying hardware. You're purchasing access to computational resources through a hosting arrangement.
Most cloud GPU arrangements qualify as service contracts because you don't have the contractual right to take possession of the hardware and it's not feasible to run the infrastructure on your own. This means your GPU compute costs are operating expenses, deductible in the year you use them.
On-demand instances: Fully deductible in the year you use them. That $10,000 you spent training your model in October? Deduct it on your 2025 taxes.
Monthly subscriptions: Deduct the full amount in the year paid, as long as it covers that tax year only.
The Reserved Instance Exception
Many AI companies commit to Reserved Instances or Savings Plans for significant discounts (up to 72% on AWS). When you prepay for multi-year commitments, you must defer the costs as a prepaid asset and recognize them over the contract period.
Example: You pay $360,000 upfront for a three-year Reserved Instance in December 2025. You can only deduct one month ($10,000) in 2025. The remaining $350,000 gets recognized proportionally in 2026, 2027, and 2028.
This is based on IRS Publication 535 rules for prepaid expenses and ASC 350-40 guidance for hosting arrangements.
Development Stage Matters: When Costs Might Be Capitalized
The stage of your AI development determines whether GPU costs are expensed immediately or potentially capitalized.
Preliminary Project Stage (Expense Everything)
You're in the preliminary project stage when you're:
Determining performance requirements for your AI application
Evaluating which foundation models or GPU configurations to use
Exploring whether existing technology can meet your needs
Deciding how to allocate resources between different projects
During this phase, all GPU costs are expensed immediately, even if you're running training experiments. The preliminary project phases for many AI applications may be longer than traditional software projects given the use of new technologies and high-risk development issues.
Application Development Stage (Consider Capitalization)
Once you've moved past preliminary planning and are building your application, you identify and capitalize direct costs. However, because cloud GPU services are service contracts, the ongoing compute costs themselves remain operating expenses. What you might capitalize are implementation costs related to setting up and configuring your training infrastructure, which are deferred as prepaid assets.
Selling Software Externally (Different Rules)
If you're building software to sell as licenses (not as a hosted service), you can't capitalize development costs until technological feasibility is established, which typically occurs late in development when all high-risk issues are resolved. Your GPU training costs during development would be research and development expenses.
Data Acquisition: A Special Consideration
Purchased training data requires careful analysis. Acquired data will likely meet the definition of an intangible asset and could be recognized separately if it has alternative future uses beyond a single project.
Expense immediately if:
The data is for a specific project with no alternative future use
You're in the preliminary project stage
The data is only for maintaining existing functionality (not adding new features)
Potentially capitalize if:
The data has alternative future uses in other projects
You're in the application development stage of internal-use software
The data enables new functionality (an upgrade, not maintenance)
Maintenance vs. Upgrades: Post-Deployment Costs
After deployment, whether ongoing GPU costs are deductible immediately or capitalizable depends on what you're doing.
Maintenance (expense immediately):
Training to keep your AI application current with recent data
Routine fine-tuning to maintain accuracy on existing tasks
Updates to prevent model degradation
Upgrades (potentially capitalize):
Training the model to perform entirely new tasks
Adding capabilities that didn't exist before
Significant improvements that enable new use cases
The distinction is whether you're adding new functionality or maintaining existing capabilities.
R&D Tax Credits: The Hidden Opportunity
If you're using cloud computing for research and development, you may qualify for R&D tax credits. A company with $1,000,000 in expenses for software engineers, contractors, and cloud computing could generate a $100,000 credit.
Cloud computing qualifies as qualified research expenses (QREs) because the infrastructure is owned and operated by someone else, located off your premises, and you're not the primary user.
What qualifies:
Training new models to solve novel technical problems
Experimenting with architectures to improve performance
Developing algorithms to reduce computational requirements
Fine-tuning models when there's technical uncertainty
What doesn't qualify:
Running production models already developed
Routine data processing
Standard maintenance
The key is documentation. Track expenses devoted specifically to your testing and development environment, not production workloads.
Practical Implementation
For monthly GPU costs:
Expense immediately as Operating Expenses
Keep monthly invoices
Track development vs. production workloads separately for R&D credits
For multi-year commitments:
Record as Prepaid Expenses initially
Amortize monthly over the commitment period
Document contract terms and payment receipts
For data acquisition:
Assess whether data has alternative future uses
Determine your development stage
Expense or capitalize accordingly
Common Mistakes to Avoid
Not tracking development stages: Companies fail to document when they move from preliminary stage to application development, making accounting treatment difficult to support.
Deducting prepaid commitments immediately: If you paid $500,000 upfront for Reserved Instances, you must recognize it over the contract period, not all in year one.
Missing the maintenance vs. upgrade distinction: Continuing to train your model after deployment could be maintenance (expense) or an upgrade (potentially capitalize) depending on whether you're adding new functionality.
Overlooking R&D credits: Many AI companies don't realize their training activities qualify or don't maintain adequate documentation.
Bottom Line
Here's what you need to remember:
Cloud GPU costs are service expenses, deductible immediately except for prepaid multi-year commitments.
Development stage matters. Preliminary project stage costs are always expensed. Application development stage costs might be capitalized, but ongoing cloud usage remains a service expense.
Maintenance vs. upgrade is critical for post-deployment training. Are you maintaining existing functionality or adding new capabilities?
R&D credits are available for development activities with technical uncertainty. Documentation is essential.
Data acquisition requires analysis of alternative future uses and development stage.
Getting GPU cost accounting right affects your EBITDA, burn rate calculations, and what your financials look like to investors. Proper treatment from the start saves you from painful corrections later.
