Choosing how to record income and expenses is one of the first real accounting decisions a small business owner makes. For most Michigan business owners, the decision comes down to cash versus accrual accounting. Choosing the wrong method early can create problems over time. Stout Tax Strategies helps St. Clair Shores businesses set up their books correctly. We also fix bookkeeping systems that started with the wrong accounting method.

This guide explains how each method works, which businesses qualify for each, and why the choice affects more than just your bookkeeping.

How Cash Basis Accounting Works

Cash basis accounting is straightforward. You record income when you receive it and expenses when you pay them. If a client pays you in December, that income belongs to December. If you pay a supplier in January, that expense belongs to January.

Most sole proprietors and small service businesses use cash basis accounting. It matches closely with your actual bank activity, which makes it easier to manage without advanced accounting knowledge. It is also the method most compatible with simple bookkeeping software and self-managed books.

The IRS permits cash basis accounting for most small businesses. However, there are restrictions. Businesses with average annual gross receipts above $30 million over the prior three years are generally required to use accrual accounting. Businesses that carry inventory may also face limitations depending on their structure and revenue level.

How Accrual Accounting Works

Accrual accounting records income when it is earned and expenses when they are incurred, regardless of when cash changes hands. If you complete a project in December but your client pays in January, that income is recorded in December under accrual. If you receive a supply shipment in December but pay the invoice in January, that expense is recorded in December.

This method gives you a more accurate picture of your business’s financial position at any given point. It matches revenue with the expenses that generated it, which is more useful for businesses with significant receivables, inventory, or multi-month contracts.

Accrual accounting is more complex to maintain. It requires tracking accounts receivable, accounts payable, and accrued liabilities alongside cash transactions. For businesses that use our bookkeeping services in St. Clair Shores, we manage that complexity and ensure the books stay aligned with tax reporting requirements throughout the year.

Cash vs Accrual Accounting Small Business Michigan: What the IRS Requires

The IRS requires each business to choose an accounting method and use it consistently. You report your method on your first tax return and apply it every year after that. Changing methods later requires IRS approval through Form 3115, Application for Change in Accounting Method. That approval process has specific rules and deadlines that vary depending on the type of change and the size of your business.

Using the wrong method, or applying your method inconsistently, creates discrepancies between your books and the income reported to the IRS by clients, banks, and payment processors. Those discrepancies are one of the most common triggers for a CP2000 notice, which proposes changes to your return based on income the IRS received from third parties. A CP2000 gives you 60 days to respond with documentation supporting your original position.

Our IRS correspondence assistance covers that response process in full. We review the notice, identify whether the discrepancy is an actual error or a timing difference between accounting methods, and respond to the IRS directly on your behalf.

Why Accounting Method Errors Attract IRS Attention

The IRS matching process compares income on your return against 1099 forms, payment platform reports, and other third-party data. Cash and accrual businesses report the same income over time, but the timing differs. If a payment processor reports a December payment that does not appear on your accrual-basis December return because it was recorded as November revenue, that mismatch triggers a flag.

The issue is usually not fraud. It is a documentation gap that requires a clear explanation of how your accounting method produced the number you reported. Without that explanation, the IRS assumes the income was unreported and issues a notice accordingly.

Good bookkeeping services in St. Clair Shores prevent these situations by keeping your records clean, your method consistent, and your year-end reporting aligned with what the IRS will see from third parties.

Which Method Makes More Sense for Your Business

The right choice depends on your business type, your revenue, and how you plan to use your financial statements.

Cash basis works well when your income and expenses are relatively predictable and close in timing, your business does not carry inventory, you manage your own books or use simple accounting software, and your revenue is below the IRS threshold that requires accrual.

Accrual works better when you have significant accounts receivable or payable, your revenue and expenses frequently fall in different periods, you need accurate monthly financial statements for business decisions, or you are planning to grow the business or seek outside financing.

Many Michigan small business owners start with cash basis and switch to accrual as their business grows. That switch requires IRS approval and careful handling of the transition period to avoid double-counting income or missing deductions.

We advise business clients across Macomb County on this decision regularly. The right method is the one that keeps your books accurate, your taxes correct, and your IRS correspondence manageable.

What Happens When Your Accounting Method Creates a Notice

If your books are not maintained consistently with your elected method, the resulting return may contain errors that generate IRS notices after filing. A balance-due notice, also called a CP14, typically arrives when the IRS believes tax was underpaid. It expects a response or payment within 21 days. A Notice of Deficiency, also called a CP3219A, is more serious. It gives you 90 days to petition the U.S. Tax Court before the IRS assesses the tax automatically.

When notices like these arise from an accounting method issue, the response requires more than just paying what the IRS says is owed. It requires demonstrating that your method was consistently applied and that the income figure on your return is correct under that method.

Our IRS correspondence assistance handles exactly this kind of response. We pull the books, compare them against the return, identify the source of the discrepancy, and provide the IRS with a documented explanation.

For Michigan business owners who want to review the IRS rules on accounting methods directly, IRS Publication 538 covers accounting periods and methods in detail, including the rules for cash and accrual basis and the process for requesting a method change. The IRS Form 3115 instructions explain the approval process for changing your accounting method if your current method is no longer appropriate for your business.

Frequently Asked Questions
