Disregarded entity, explained
A single-member LLC is treated as a “disregarded entity” for federal income tax purposes by default. This means the IRS effectively ignores the LLC as a tax-filing entity and treats your business income as if you were a sole proprietor: you file Schedule C with your personal Form 1040, you pay self-employment tax on Schedule SE, and your tax obligations look identical to those of a sole proprietor.
What is not ignored is the LLC's legal status. For state law purposes, the LLC is a separate legal entity. It can sign contracts in its own name. It can own property. Critically, it shields your personal assets from business liabilities: if a creditor sues the LLC, they can pursue LLC assets but not your personal house, car, or savings, provided you have respected the legal separation.
The accounting consequence: the books MUST be separate. Your business bank account should be a business bank account. Personal expenses should never run through it. Owner draws (you transferring money from the business to yourself) should flow through a designated owner-draw account in the chart of accounts, not as ad-hoc “miscellaneous” transactions. This separation is sometimes called avoiding “piercing the corporate veil”, and it is the single most important bookkeeping discipline of LLC ownership.
What changes vs sole proprietorship
The tax treatment is identical by default, but four practical things change:
- Separate business bank account. Strongly recommended for sole proprietors, near-mandatory for LLCs. The accounting software needs to connect to this account specifically; mixing personal feeds into the business books defeats the purpose.
- Separate expense tracking. Every expense in your business books should be a business expense. Personal Amazon orders, personal coffee, personal phone bills (unless you formally allocate the business-use portion) should not appear in the business chart of accounts.
- Same tax form by default. Schedule C with your personal return. Same self-employment tax. Same quarterly estimated payments. The LLC has not changed the tax math; it has changed the legal posture.
- Optionality to elect S-Corp later. When the business reaches a profit level where S-Corp self-employment tax savings exceed S-Corp compliance cost, you can file Form 2553 to elect S-Corp treatment without changing the underlying LLC. This is an important option to keep open; it affects the software you pick now.
The five decision pivots for a single-member LLC
The four sole-prop pivots apply (revenue range, service vs product, subcontractors, quarterly estimated taxes), plus one new one specific to LLCs:
Feature checklist for a single-member LLC
Sole-prop must-haves plus these LLC-specific items:
- • Bank account isolation. The software must support connecting to a single business account cleanly, with no personal feeds bleeding in.
- • Owner-draw category in the chart of accounts. A dedicated equity account for owner draws (not an expense account), so distributions are tracked correctly.
- • Accountant access. Most LLC owners eventually engage a CPA at tax time. The software should let you grant accountant view or edit access without paying for an additional user seat.
- • Payroll-readiness, if S-Corp election is on the horizon. Either native payroll or clean integration with a major payroll provider.
- • State-specific reporting. Some states (California, Tennessee, others) require an LLC franchise tax or annual report; the software does not file these but should produce clean reports for you to use.
Category recommendations
| Category | Fit | Why |
|---|---|---|
| Free / low-barrier | Acceptable fit | Viable for service-based single-member LLCs under $50k revenue with no employees and no S-Corp plans. Lacks payroll, which becomes mandatory if you elect S-Corp later. |
| Mainstream small-business cloud | Strong fit | The default fit for most single-member LLCs. Handles separate accounts, owner draws, accountant access, and is ready for S-Corp election when you make that move. |
| Service-business specialist | Acceptable fit | Reasonable if invoicing is the daily pain point and your CPA is comfortable with the product. Some specialists are weaker on payroll integration. |
| Ecommerce / inventory specialist | Acceptable fit | Only if your single-member LLC sells physical product across multiple channels at meaningful volume. |
| Mid-market | Not the fit | Almost no single-member LLC has the multi-entity or scale needs that justify mid-market category cost. |
| Managed bookkeeping services | Acceptable fit | A defensible choice if you genuinely will not do bookkeeping yourself; particularly if S-Corp election is imminent. |
Frequently asked questions
Is my single-member LLC taxed differently from a sole proprietorship?
By default, no. The IRS treats a single-member LLC as a disregarded entity for federal income tax purposes, meaning you file the same Schedule C as a sole proprietor. The accounting requirements for tax purposes are identical. What changes is the legal posture: the LLC is a separate legal entity for liability, contract, and creditor purposes, which means your books MUST be separate from personal accounts to preserve the liability shield. See llcvsscorp.com for the structure-decision discussion.
What is the consequence of commingling personal and business funds in an LLC?
Commingling can pierce the corporate veil. If a creditor or plaintiff later argues that you treated the LLC as an extension of yourself rather than a separate entity, courts can disregard the limited liability protection the LLC was supposed to provide. The bookkeeping consequence: every transaction in your business bank account should be a business transaction, owner draws should flow through a designated owner-draw account, and personal expenses should never appear on the business books.
Should I pick software now that supports payroll, in case I elect S-Corp later?
Yes, if S-Corp election is plausible in the next 12 months. Switching accounting software because your payroll-pairing changed is more painful than starting on a product that handles both. Mainstream cloud accounting products generally pair with multiple payroll providers, so you are not locked in to a specific payroll choice; you just want the accounting product to be in a category that can integrate cleanly when the time comes. See /feature/payroll-integration for the chapter on payroll integration.
Do I need an EIN for the LLC, and does that change my software setup?
Most single-member LLCs need an EIN if they hire employees or if they elect S-Corp treatment. Many also obtain one to open a business bank account, even when not strictly required. The EIN does not change your accounting software setup, but you will use it on contractor 1099s, on your business tax returns, and as the tax-ID on file with banks and payment processors. Apply for it free at IRS.gov.
Can I use the same accounting software my CPA recommends?
Yes, and you should weight their preference heavily. CPAs who specialise in small-business clients are usually fluent in QuickBooks Online and Xero in the United States; some also work in FreshBooks, Wave, or specialised products. Switching software later because your CPA cannot work efficiently in the tool you picked is meaningfully more painful than the small loss of optionality you accept by following the recommendation.
