Answer
Should I use cash or accrual accounting as a 1099 contractor?
Short answer
Most 1099 contractors and small service businesses should use cash-basis accounting. Under cash accounting, income is recorded when payment is received and expenses when paid, which matches how most sole proprietors and small S-corps experience their cash flow and their bank accounts. Accrual accounting records income when earned and expenses when incurred, regardless of when cash moves. The IRS requires accrual only for C-corps and tax shelters exceeding $30 million in average annual gross receipts. For most 1099 businesses, cash is the correct and simpler choice.

Most self-employed individuals use cash method. It matches income to when money actually hits your account, giving you timing flexibility at year-end.
Cash-basis mechanics: you invoice a client in December and receive payment in January. Under cash accounting, the income is January revenue. Under accrual, it is December revenue. For tax purposes, the difference is significant: cash accounting avoids paying tax on income you have not yet received. This is particularly valuable for contractors with delayed payment terms, large project-end invoices, or lumpy revenue.
The accrual threshold: C-corps, partnerships with C-corp partners, and tax shelters with average annual gross receipts exceeding $30 million (indexed for inflation) must use the accrual method under IRC §448. Service businesses (consultants, therapists, advisors, agency owners) that are S-corps, sole proprietors, or partnerships are generally exempt from this requirement and may use cash accounting regardless of revenue.
Inventory exception: businesses that hold and sell inventory must use accrual for inventory regardless of size. This does not apply to service businesses. A consultant who sells templates or digital products typically does not hold inventory in the IRS sense.
Consistency requirement: once you choose an accounting method, you must use it consistently. Switching from cash to accrual or vice versa requires IRS approval via Form 3115 (Application for Change in Accounting Method) and requires adjusting income and expenses for the year of change to avoid double-counting or gaps. The process is manageable but adds complexity. Choose correctly at the start.
When accrual might make sense: if your business has grown to the point where management needs financial statements that reflect economic reality (large outstanding receivables, significant unpaid bills), accrual gives a more accurate picture of business performance for internal decision-making. Many businesses maintain cash-basis books for tax purposes and request accrual-adjusted financial statements for loan applications or board review. Your bookkeeper or accountant can produce both from the same underlying data.
