Cash vs. Accrual Accounting for Taxes:  Which Method Is Right for Your Business?

06.27.25 12:01 AM By Michael D'Amato, CPA

When it comes to running a business, choosing the right accounting method isn’t just about compliance—it can also have a significant impact on your tax liability and cash flow.

The two primary methods of accounting for tax purposes are the cash method and the accrual method. Each has its pros and cons, and the method you choose can affect not only when you pay taxes but also how you manage your finances year-round.

So, which method is best for your business? Let’s break it down.


Understanding the Two Methods

The Cash Method

With cash accounting, income is recorded when payment is received, and expenses are deducted when they’re actually paid. It’s straightforward and offers more flexibility when it comes to tax planning.

The Accrual Method

In contrast, the accrual method records income when it’s earned and expenses when it’s incurred, regardless of when money changes hands. While it provides a more accurate picture of your company’s financial health, it limits your ability to shift income or expenses for tax advantage.


Why the Choice Matters

Your accounting method determines how—and when—income and expenses are reported to the IRS. That directly influences your taxable income, tax payments, and even your ability to manage cash flow efficiently.

For example, under the cash method, a business could delay invoicing customers until January to defer income into the next tax year. Or it could accelerate deductible expenses by paying bills in December instead of January.

This timing flexibility isn’t possible under the accrual method, which is based on economic activity rather than actual cash flow.


Who Can Use the Cash Method?

Thanks to the Tax Cuts and Jobs Act (TCJA), more small businesses can now use the cash method. For tax year 2025, a “small business” is defined as one with average annual gross receipts of $31 million or less over the prior three years. If your business falls within that threshold, you can enjoy several benefits:

  • Simplified inventory accounting
  • Exemption from uniform capitalization (UNICAP) rules
  • Exemption from the business interest deduction limitation

Additional proposals could expand these limits even further for certain industries, like manufacturing.

Also eligible (even if they exceed the gross receipts test):

  • S corporations
  • Partnerships without C corporation partners
  • Farming businesses
  • Certain personal service corporations

However, tax shelters are explicitly ineligible for the cash method, regardless of size.


When the Accrual Method Might Be Better

While the cash method offers tax and cash flow advantages for many, the accrual method may be more appropriate in certain scenarios. For example:

  • If your accrued expenses consistently exceed accrued income, accrual accounting could reduce your tax liability.
  • You can deduct year-end bonuses paid within 2.5 months of year-end.
  • You may be able to defer taxes on advance payments, such as deposits or subscriptions.

Additionally, companies that prepare financial statements in accordance with U.S. Generally Accepted Accounting Principles (GAAP) are required to use the accrual method. That could mean maintaining two sets of books—one for taxes and one for financial reporting—if you still wish to use cash for IRS filings.


Is It Worth Changing Your Method?

Switching accounting methods can offer tax savings—but there are trade-offs. Here’s what to consider:

  • Administrative complexity: Maintaining both cash and accrual records may increase accounting costs.
  • IRS consent required: Changing your accounting method isn’t automatic. You must file Form 3115 and receive IRS approval.
  • Long-term implications: Some changes may affect how income and expenses are recognized in future years.

Make the Smart Choice

There’s no one-size-fits-all answer. Your industry, growth stage, financial goals, and even your financing needs can all influence whether the cash or accrual method is best for your business.

Before you make any changes, it’s essential to weigh the benefits against the administrative burden—and understand how it affects both your taxes and your books.
