A chart of accounts for a practice of one

What a chart of accounts is, and why the generic template misses a practice

A chart of accounts is the labeled list of buckets every dollar flows through, the backbone of your books and, at tax time, the map to your return. The off-the-shelf small-business template almost fits a practice, but it misses three healthcare-specific realities: revenue billed rarely equals revenue collected, patient prepayments are a liability until earned, and the owner's tax money is not an expense. Fix those three and the rest is standard.

The five families are the same everywhere: assets (what the practice owns), liabilities (what it owes), equity (the owner's stake), income (what it earns), and expenses (what it spends). What differs for a clinical practice sits inside the income and equity families. Set up the practice bank account and a card processor first, then build the account list to mirror how money actually moves: charge, adjust, collect, spend, draw.

Your books software ships with a default chart of accounts; treat it as a starting point to prune, not a finished structure. A lean, practice-shaped chart is what later lets you read the p&l in ten minutes instead of an hour.

The five account families, mapped to a practice

A solo practice runs comfortably on thirty to forty accounts, enough to see the practice clearly, few enough to close the month quickly. Group them by family and number them in blocks (assets in the 1000s, liabilities 2000s, equity 3000s, income 4000s, expenses 5000s and up) so a new account has an obvious home. The table below is a working skeleton; prune what you do not use.

Notice what is not on the list: a line for the income tax you pay yourself. Owner income tax is personal, and it never becomes a practice expense, a point the owner's-accounts section returns to.

Income accounts: gross charges, contractual adjustments, and net collections

The single most important practice-specific move is to separate what you billed from what you were paid. Bill a payer $200, the contract allows $120, and the $80 difference is a contractual adjustment, a contra-income account that reduces gross charges to net revenue. It is not an expense and not bad debt. Booking it correctly keeps both your gross production and your real collected revenue visible on the same page.

Contractual adjustment vs. bad debt. A contractual adjustment is the amount you agreed in advance never to collect, the payer's contracted write-down. Bad debt is different: a balance the patient genuinely owes and does not pay. Keep them in separate accounts, because they tell you different things. A rising contractual-adjustment ratio means your payer mix or fee schedule is eroding your rate; rising bad debt means your patient-collection process is leaking.

This is also why you carry two a/r numbers: what the practice-management system shows as outstanding charges, and what the books show as collectible receivable after expected adjustments. They rarely match, and the gap is normal, the books number being the honest one.

A denied claim is a third bucket. A charge denied because prior auth as a solo was never obtained is not a contractual adjustment and not really bad debt; it is revenue you recorded and will never see. A separate write-off account for denials tells you, in dollars, what front-desk gaps are costing, which is exactly the number worth watching monthly.

The payoff of the whole income structure is one monthly view: gross charges, minus contractual adjustments, minus denials and bad debt, equals what you actually collected. When that bottom line drifts while your session count holds steady, the account that moved tells you where to look first, at your fee schedule, a single payer, or the front desk, instead of leaving you to guess which of the three is leaking.

Expense accounts that mirror Schedule C

Name your expense accounts to match the categories on Schedule C, the form a self-employed clinician files, and tax prep becomes a copy job instead of a reclassification project 1Ref 1Internal Revenue Service (2026).Self-employed individuals tax center.That a self-employed clinician reports practice income and expenses on Schedule C, the structure the chart of accounts mirrors, and pays self-employment tax and estimated tax personally rather than as a practice expense.. The governing rule for every one of them is the same: an expense is deductible only if it is ordinary and necessary to the practice 2Ref 2Internal Revenue Service (2026).Guide to business expense resources.The ordinary-and-necessary standard that governs which practice costs (CE, licensure, supervision, malpractice, occupancy) belong in deductible expense accounts.. That standard covers the costs a clinician actually carries, from continuing education and licensure to malpractice premiums and rent.

• Licensure and board fees map to the taxes-and-licenses category.
• Continuing education, supervision, and professional dues map to professional development and other expenses.
• Malpractice and business insurance map to insurance.
• Rent, utilities, and a home-office allocation map to the occupancy lines.
• EHR, practice-management, and telehealth software map to subscriptions and other expenses.
• Merchant processing fees are an expense in their own right.

The last one hides a common error. If the card processor deposits your revenue already net of its fee, still record the full charge as income and the fee as a separate expense. Netting them understates both your true revenue and a real cost, and it quietly breaks every benchmark you later try to run against your own numbers.

Fixed assets vs. expenses: what gets capitalized

Not everything you buy is an expense. Furniture, a testing kit, a computer, or an office build-out with a useful life beyond the year is a fixed asset, recorded in an asset account and written off over time through depreciation, or expensed immediately under the Section 179 election or bonus depreciation 3Ref 3Internal Revenue Service (2026).Publication 946, How To Depreciate Property.That equipment with a useful life beyond the year is capitalized and depreciated, or expensed under the Section 179 election or bonus depreciation, rather than treated as a supply.. Supplies and small items are expensed as you buy them. The account structure is the same either way: a fixed-asset account plus accumulated depreciation.

Set a capitalization threshold. Many practices adopt a policy of capitalizing items above a set dollar amount and expensing anything below it, so a stapler never lands in the fixed-asset ledger. Whatever line you pick, apply it consistently and write the policy down; a consistent, documented rule is what an examiner expects to see.

Whether a given purchase is better expensed now under Section 179 or depreciated over its life is a timing decision with real tax consequences that turn on your income for the year and years ahead. The mechanics live in Publication 946 3Ref 3Internal Revenue Service (2026).Publication 946, How To Depreciate Property.That equipment with a useful life beyond the year is capitalized and depreciated, or expensed under the Section 179 election or bonus depreciation, rather than treated as a supply.; the choice for your specific numbers is one to run with your CPA rather than default.

Owner's accounts: draws, the tax reserve, and why estimated tax is not an expense

For a sole proprietor or single-member LLC, you are not an employee of your own practice; money you take out is an owner's draw, recorded in equity, never as an expense 1Ref 1Internal Revenue Service (2026).Self-employed individuals tax center.That a self-employed clinician reports practice income and expenses on Schedule C, the structure the chart of accounts mirrors, and pays self-employment tax and estimated tax personally rather than as a practice expense.. The most useful habit here is a tax reserve: sweep a fixed percentage of every deposit into a separate savings account, so the quarterly estimated payments the IRS expects are already funded when they come due 4Ref 4Internal Revenue Service (2026).Estimated taxes.That estimated tax is paid quarterly under safe-harbor rules, funding the practice's tax-reserve account, and is a personal payment booked as an owner's draw rather than a business expense..

Estimated tax is not a business expense. This is the misclassification that quietly overstates a practice's expenses and understates its profit. Your federal and state income tax, and your self-employment tax, are personal obligations paid out of your draw; book the payment against owner's draw, not against an expense account 4Ref 4Internal Revenue Service (2026).Estimated taxes.That estimated tax is paid quarterly under safe-harbor rules, funding the practice's tax-reserve account, and is a personal payment booked as an owner's draw rather than a business expense.. The quarterly cadence (roughly April, June, September, and the following January) and the safe-harbor rules that avoid an underpayment penalty are worth calendaring the day you open the reserve account 4Ref 4Internal Revenue Service (2026).Estimated taxes.That estimated tax is paid quarterly under safe-harbor rules, funding the practice's tax-reserve account, and is a personal payment booked as an owner's draw rather than a business expense..

Owner retirement is also personal. A contribution to a solo 401(k), which covers an owner with no employees, is generally taken at the owner level rather than as a practice operating expense for an unincorporated owner 5Ref 5Internal Revenue Service (2026).One-participant 401(k) plans.That a solo 401(k) covers an owner with no employees, and the owner's own contribution is taken at the owner level rather than as a practice operating expense for an unincorporated owner.. The exact treatment changes with your entity and tax election, so set it with your CPA, but keep the contribution visible in your books as a draw so cash planning stays honest.

Contractor pay and the 1099 account

If the practice pays a clinical supervisor, an outside biller, or a 1099 clinician, keep those payments in a dedicated contract-labor account. Payments of $600 or more to a nonemployee for services generate a Form 1099-NEC at year end, and a single clean account turns that January filing into a report rather than an archaeology dig through your checking register 6Ref 6Internal Revenue Service (2026).About Form 1099-NEC, Nonemployee Compensation.That payments of $600 or more to a nonemployee for services require a Form 1099-NEC, supporting a dedicated contract-labor account for supervisors, billers, and 1099 clinicians.. Collect a Form W-9 before the first payment, not after.

One caution lives next door to bookkeeping: whether an added clinician can be paid as a 1099 at all is a worker-classification question, not an accounting one, and the misclassification exposure falls on the practice. Book the payments cleanly, but settle the classification before you write the first check.

If you also sell products or take retail-style payments, add a separate income account and, where it applies, a sales-tax-payable liability, so the money you are merely holding for the state never looks like revenue on your own books.

Keeping it lean, and keeping the records

Resist opening an account for every vendor. A solo practice stays legible on thirty to forty accounts; over-granularity buries the signal you built the books to see. Merge rarely-used lines, and split an account only when you need to watch that number every month. Then protect the source documents behind the numbers: the receipts, statements, and 1099s that substantiate every line.

The IRS's general guidance is to keep business records for three years, six years if income was substantially understated, and four years for employment-tax records; when in doubt keep them longer, and keep anything supporting an asset's basis until you dispose of it 7Ref 7Internal Revenue Service (2026).Recordkeeping.The record-retention periods (generally three years, six for substantial underreporting, four for employment-tax records) for the source documents behind the books.. Store them so a specific line item can be traced to its receipt in minutes, which is the whole test an audit applies.

Build the chart once, review it once a year, and two downstream jobs get easier: the annual budget in an afternoon becomes a copy-forward exercise, and the monthly close stops surprising you. A chart of accounts is not paperwork for its own sake; it is the instrument that turns a year of transactions into a practice you can actually read.
