Cash basis accounting records income when payment is received and expenses when they are paid. Nothing is booked for invoices sent or bills received until money actually moves. Accrual basis accounting records income when it is earned and expenses when they are incurred, whether or not cash has changed hands. Cash basis is simpler and follows your bank balance; accrual shows how the business performed in the period and is the method GAAP requires.
Which one you may use is not purely a preference. IRS rules and GAAP decide it for many businesses, and the IRS threshold changed recently. This guide covers what cash basis means, who qualifies in 2026, how it compares with accrual, and when it is time to switch. Our bookkeeping services keep books on either method and can run both views side by side.
What is cash basis of accounting?
Cash basis accounting is a way of recording income and expenses only when money moves in or out of the business.
- You record income when you receive the payment.
- You record expenses when you pay the bill.
The IRS describes it in Publication 538: under the cash method you generally report income in the tax year you receive it and deduct expenses in the tax year you pay them.
Two details catch people out.
Constructive receipt. Income counts as received when it is credited to your account or made available to you without restriction, even if you have not taken possession of it. A payout sitting in your payment processor balance on December 31, available to withdraw, is generally income for that year.
Prepayments. Paying next year’s expenses early does not always produce a deduction this year. Publication 538 says an expense paid in advance is deductible only in the year it applies to, with an exception (the 12-month rule) for benefits that do not extend beyond 12 months after they begin or the end of the following tax year.
What is the accrual basis of accounting?
Accrual accounting records income and expenses when they happen, even if no money has moved yet. You record income when you deliver the product or finish the work, and expenses when you receive the goods or service. It matches income with the costs that produced it. For the mechanics of accruals, deferrals and the journal entries behind them, see our full guide to accrual accounting.
Cash basis vs accrual basis: how do they differ?
Both methods track the same money, but they tell different stories. Cash basis shows what is happening in your bank account. Accrual shows what is happening in your business.
| Category | Cash basis accounting | Accrual accounting |
|---|---|---|
| When you record income | When payment reaches you | When you deliver the product or finish the work |
| When you record expenses | When you pay the bill | When you receive the goods or service |
| Accounts receivable and payable | Not on the books | Tracked |
| View of the business | Short-term cash movement | Performance for the period |
| Profit accuracy | Swings with payment timing | Matches revenue with its costs |
| Tax timing | Taxed when cash arrives, deducted when paid | Taxed when earned, deducted when incurred |
| Complexity | Simple | More detailed, with month-end adjustments |
| GAAP | Not GAAP | Required under GAAP |
A worked example: the December invoice
A brand ships a $30,000 wholesale order on December 20. The retailer pays on January 25. The same brand pays a $5,000 packaging bill on January 5 for materials received and used in December.
| Cash basis | Accrual basis | |
|---|---|---|
| December income | $0 | $30,000 |
| December expense | $0 | $5,000 |
| January income | $30,000 | $0 |
| January expense | $5,000 | $0 |
| Tax year of the $25,000 profit | The following year | The year of the sale |
The profit is the same. What changes is which month and which tax year it lands in. That is the main reason owners like cash basis: it can defer tax on year-end sales. It is also its main weakness, because December looks worse than it was and January looks better.
Who can use cash basis accounting in 2026
The rules come from Publication 538 and the annual inflation adjustments.
- Sole proprietors, S corporations and partnerships with no C corporation partners can generally use the cash method, subject to the inventory point below.
- C corporations, partnerships with a C corporation partner, and tax shelters generally cannot, unless they pass the gross receipts test. Tax shelters cannot use it at all.
- The gross receipts test. An entity passes if its average annual gross receipts for the three prior tax years do not exceed the inflation-adjusted limit. For tax years beginning in 2026 the limit is $32,000,000, per Revenue Procedure 2025-32, section 4.30. Publication 538, last revised in 2022, still prints $26 million, but the figure is indexed for inflation and rises most years, so articles that quote $26 million are out of date.
- Failing the test means changing to an accrual method for the year the entity fails it.
Is cash basis still an option if I hold inventory?
Often, yes. This is the most common misunderstanding. A small business taxpayer that meets the gross receipts test can choose not to keep an inventory for tax, and instead treat it as non-incidental materials and supplies (deducted when the items are sold or used) or follow the treatment in its financial statements. That lets many product businesses use the cash method for tax. Larger inventory businesses generally account for purchases and sales on accrual. Check the specifics with your tax adviser, because the choice interacts with how you keep your books.
Cash for taxes, accrual for management
Many growing brands keep accrual books for management and lenders and file on the cash method where they qualify. The accounting software holds one set of transactions; the tax preparer converts accrual figures to cash at year end. The two are not in conflict.
Pros and cons of cash basis accounting
Cash basis accounting is popular with small businesses for its ease of use. Its simplicity comes with limits.
Pros
- Simple to use. You record transactions only when money moves. No receivables, payables or month-end accruals.
- A clear view of cash on hand. Your books track the bank balance, so you know what is available to spend.
- Tax timing. Income is not taxed until it is received, which can defer tax on sales made late in the year.
- Lower bookkeeping effort. Fewer adjustments mean less work each month.
Cons
- Profit can look misleading. A month looks strong because several customers paid at once, or weak because a large bill was paid early.
- No view of what is owed. Unpaid customer invoices and supplier bills sit outside the books, so you can be surprised by either.
- Not GAAP. If you need audited statements, or lenders and investors want to review your financials, cash basis will not meet their standard.
- Not open to every business. Larger C corporations and some partnerships must use accrual for tax.
Pros and cons of accrual accounting
Pros
- Shows the real performance of the business. Income and costs are recorded when the work happens, so each month’s margin is meaningful.
- Required for audits, investors and lenders. US GAAP and IFRS are accrual frameworks, and their shared revenue standard (ASC 606 and IFRS 15) recognizes revenue when goods or services transfer, not when cash arrives.
- Supports planning. Receivables, payables and deferred revenue show what is coming in and going out.
Cons
- More work to maintain. Unpaid invoices and bills must be tracked and adjusting entries made at every period end.
- Profit can look stronger than your cash balance. The statements can show profit while cash is tied up in receivables or stock.
- Tax on money not yet received. Income is generally taxed when earned, not when collected.
Modified cash basis
Some businesses use a hybrid, often called modified cash basis: cash for everyday income and expenses, with accrual treatment for a few items such as fixed assets and depreciation, loans, or inventory. It gives a fuller balance sheet than pure cash without full accrual bookkeeping. It is not GAAP, and for tax Publication 538 allows a hybrid of cash and accrual only when the combination clearly reflects income and is used consistently.
When to choose cash basis vs accrual basis
| Choose cash basis when | Choose accrual basis when |
|---|---|
| You qualify under the IRS rules and want simple books | You need GAAP statements for audits, loans, investors or a sale |
| Customers pay at the point of sale | You invoice customers or give payment terms |
| Few unpaid bills at any time | You receive supplier bills that are paid later |
| No lender or investor reporting | You sell preorders, subscriptions or gift cards |
| Low transaction complexity | Inventory and marketplace settlements make timing matter |
| You mostly need to know cash on hand | You need to know what you actually earned and owe each month |
How to switch from cash to accrual
Switching for tax is a change of accounting method. It generally needs IRS consent, requested on Form 3115, and the change comes with an adjustment under section 481(a) so that no income or expense is counted twice or missed. On the bookkeeping side the steps are:
- Pick a switch date, usually the first day of a fiscal year.
- Build opening balances for receivables, payables, accrued expenses, deferred revenue, prepaids and inventory as of that date.
- Set up the month-end routine: cut-off, accruals, deferrals and reconciliations.
- Run the first few closes with a reviewer checking every adjusting entry.

Cash basis follows the movement of money in and out of your bank account. Accrual basis records income and expenses when the transaction occurs, even if payment comes later. If you are small, qualify under the IRS rules and mostly need to know your cash, cash basis may be enough. If you invoice customers, sell preorders or subscriptions, carry meaningful inventory or want GAAP statements, accrual is the method to run your business on.
Atidiv’s finance and accounting team keeps books on either method, closes them every month and hands your tax preparer clean year-end numbers. See our bookkeeping services for small businesses or contact us to book a call.
Frequently asked questions
What is cash basis accounting?
Cash basis accounting records income when payment is received and expenses when they are paid. It ignores unpaid invoices and bills until cash moves.
What is the cash basis in simple terms?
Money in is income on the day it arrives, and money out is an expense on the day it leaves. Your books follow your bank account.
Which method, cash basis or accrual basis, gives me a better view of my business?
Cash basis shows the money you have today but can hide unpaid bills and income already earned. Accrual shows what you earned and owe in the period. For budgeting, margins and planning, accrual gives the fuller picture.
Can switching methods lower my taxes?
It changes when income is taxed, not how much you earn. On the cash method a customer who pays in the next year moves that income into the next year. A method change for tax generally needs IRS consent on Form 3115.
What if my profit looks strong on paper but my bank balance is low?
That is the gap between accrual profit and cash. It usually means receivables, inventory or prepaid costs are holding your cash. Track receivables, tighten payment terms and forecast cash alongside the profit and loss statement.
What is the IRS limit for cash basis accounting in 2026?
For tax years beginning in 2026, a corporation or partnership passes the gross receipts test if its average annual gross receipts for the prior three tax years do not exceed $32 million.
Is cash basis GAAP?
No. GAAP requires accrual accounting. Cash basis and modified cash basis statements are acceptable for many small businesses and some lenders, but not for GAAP-audited financials.
