Excite Tax's answer for Utah owners: map each account to a line on Form 1120-S or Schedule C, so the books total to the return without reclassing.
Excite Tax's answer: build it backwards from the tax return. Give each expense line the business actually uses on Schedule C Part II (or Form 1120-S page 1) its own account, add the balance-sheet accounts the bank and loans need, and stop there. Sub-accounts earn their place only when someone reads them every month. The full map is below.
Excite Tax's answer: it is the list of every bucket a business sorts money into, in five groups: assets, liabilities and equity (the balance sheet), then income and expenses (the profit and loss). The IRS does not prescribe one; any system that clearly shows income and expenses will do, as long as the books show gross income, deductions and credits.
Excite Tax's answer: ask one question of each transaction: which line of the return does this land on? A contractor's invoice is contract labor, not wages; a draw to the owner is equity, never wages; a loan payment splits into principal (the loan account) and interest (line 16b). A worked month of transactions is below.
Excite Tax's answer: make one Cost of Goods Sold account per line of Schedule C Part III (purchases, labor, materials, other costs such as freight in) and an Inventory asset account, then count inventory at year end. In QuickBooks the expense accounts take the Cost of Goods Sold account type. The arithmetic, with numbers, is below.
Excite Tax's answer: short. Job materials, subcontractors on the contract labor line, technician wages, vehicles, tools, advertising, insurance and licences cover most of a plumber's, HVAC or cleaning company's spending. The sample chart is below.
Excite Tax's answer: the franchisor often dictates the account list, so keep its names and map each one to the return. Two accounts need care: the initial franchise fee is amortized over 15 years, and royalties based on sales are deducted as they are paid. The example is below.
A chart of accounts is only a list of names. What makes one good is that every name adds up, without edits, to a number the tax return asks for. The law does not require a particular chart: any recordkeeping system that clearly shows income and expenses is acceptable, provided the books show gross income, deductions and credits. So the fastest route to a useful chart is to copy the return's own lines.
Software templates tend to go wrong in two directions. Some ship with dozens of accounts nobody uses, which invites the same bill to land in three places. Others lump everything into a few broad buckets, so year-end means reopening every receipt to split them. A chart built from the return avoids both.
Which return? A sole proprietor or single-member LLC files Schedule C. An S corporation files Form 1120-S. A multi-member LLC files a partnership return whose deduction lines look much like the S corporation's. Choose the chart for the entity the business is now, and rename accounts later if it elects S status.
Most bookkeeping software numbers the groups in that order and leaves gaps between account numbers so a new account can slot in later. The numbers matter less than the names: one account per question the return asks, and no account whose contents need explaining.
Excite Tax's map of the income and expense side, line by line, for both returns. The first column is a sensible account name; the others are where its total lands on Schedule C (2025) and on Form 1120-S (2025).
Income and expense accounts and their return lines (Schedule C Part I, Part II; Form 1120-S page 1; line 20 instructions)
Two rows deserve a note. Meals get their own account because only part of the cost is deductible, and a mixed "meals and entertainment" account forces a year-end split. Anything that falls to Part V has to be listed by type and amount anyway, so a "miscellaneous" account saves no work; name the real thing instead.
Some spending has no expense account at all. Equipment, furniture, permanent improvements, personal spending, charitable gifts and government fines are kept out of the other-expenses list. Equipment goes to an asset account and reaches the return through depreciation; personal spending and gifts belong in owner draws.
The balance sheet side is simpler, and the S corporation form spells it out. Schedule L should agree with the corporation's books and records, so an account list that mirrors it saves a reconciliation later. A sole proprietor has no balance sheet on the return but needs the same accounts to reconcile the bank.
Balance sheet accounts, with the matching Schedule L (Form 1120-S) line
| Account | What goes in it | Schedule L line |
|---|---|---|
| Checking, savings | Each bank account on its own, reconciled monthly | Line 1, cash |
| Accounts receivable | Invoices sent, not yet paid (accrual books only) | Line 2a |
| Inventory | Goods on hand for sale, at cost | Line 3 |
| Loans to shareholders | Money the business lent an owner | Line 7 |
| Vehicles and equipment; accumulated depreciation | Cost of long-lived assets, and the depreciation taken on them | Lines 10a and 10b |
| Accounts payable; credit cards | Bills and card balances owed | Line 16, or line 18 for other current liabilities |
| Sales tax payable; payroll liabilities | Tax collected or withheld, owed to the government | Line 18, other current liabilities |
| Loans from shareholders | Money an owner lent the business | Line 19 |
| Bank and vehicle loans | The principal still owed | Line 20, or line 17 when due within a year |
| Capital stock; retained earnings | What owners put in, and profit kept from earlier years | Lines 22 and 24 |
A small S corporation may be excused from filling in the schedule: Schedules L and M-1 are not required when total receipts and year-end total assets are both under $250,000. Keep the accounts anyway. The balance sheet is how the books prove themselves, and loans to and from shareholders are exactly the balances that get questioned.
Three accounts separate an S corporation's chart from a sole proprietor's. First, the owner's pay: officers' compensation goes on line 7, apart from other wages on line 8, so run it through payroll into its own account. Second, distributions: they are an equity account, reported on Schedule K line 16d, never an expense. Third, items the shareholders report themselves, such as cash charitable contributions on Schedule K line 12a, stay out of line 20's other deductions.
Excite Tax's example: the owner of a Sandy S corporation takes $5,000 a month through payroll and a $10,000 distribution in June. The $60,000 of salary goes to Officer compensation, which lands on line 7. The $10,000 goes to Shareholder distributions, an equity account reported on Schedule K line 16d, and reduces nobody's profit. Payments to an officer are treated as wages to the extent they are reasonable pay for the work, so a chart with no officer-compensation account is a warning sign. How distributions interact with the owner's basis is in S corporation shareholder basis.
A business that makes or resells goods needs a cost of goods sold group that mirrors Schedule C Part III, or Form 1125-A for an S corporation. In QuickBooks or any other ledger, set up these accounts:
Excite Tax's example: an Orem online shop starts 2025 with $12,000 of inventory (line 35), buys $48,000 of goods (line 36) and pays $1,500 of inbound freight (line 39). The year-end count shows $15,000 still on the shelves (line 41). Cost of goods sold is $12,000 plus $48,000 plus $1,500, less $15,000: $46,500 on line 42, carried to line 4. If the purchases had been booked straight to an expense account with no inventory count, the return would claim $61,500 and overstate the cost by the $15,000 of ending inventory still unsold.
A small business can take a simpler road. A small business taxpayer can choose not to keep an inventory and treat goods as non-incidental materials and supplies, deducted in the year they are first used or consumed. That still means tracking what was used, not what was bought, so the chart barely changes. Whether the business qualifies turns on the gross receipts test explained in cash vs accrual accounting. More on product businesses is in ecommerce bookkeeping.
A plumbing, HVAC, landscaping or cleaning company runs on a short list. The trap is not too few accounts but the wrong ones: materials mixed with tools, helpers paid as contractors in one month and as employees the next, and the owner's truck payment recorded as an expense.
Sample chart for a home service business (Schedule C Part II lines; Part III)
| Account | What goes in it | Return line (sole proprietor) |
|---|---|---|
| Service revenue | Every job invoice | Line 1 |
| Job materials | Parts and materials installed at a customer's home | Part III line 38 when resold to customers; otherwise line 22, supplies |
| Subcontractors | Other trades paid by the job, not on payroll | Line 11, contract labor |
| Technician wages | Employees on payroll | Line 26 |
| Payroll taxes | The employer's share of payroll tax | Line 23, taxes and licenses |
| Vehicle fuel and repairs | Service vans and trucks | Line 9, car and truck expenses |
| Small tools and supplies | Tools used up within about a year | Line 22, deducted as used |
| Vehicles and equipment (asset) | Trucks, trailers and machines that last for years | Recovered through depreciation, line 13 |
| Advertising | Online ads, yard signs, directory listings | Line 8 |
| Insurance | Liability, vehicle and bonding | Line 15 |
| Licences and permits | State and city licences, job permits | Line 23 |
| Phone and software | Phones, scheduling and dispatch apps | Line 25 for phones; Part V for software |
Pick one home for job materials and keep it. If the business resells parts as a line on the invoice, cost of goods sold shows the gross margin on each job; if materials are simply used up, supplies is fine. Switching between the two mid-year is what makes the profit and loss unreadable. For builders with progress billing and retainage, see construction bookkeeping.
Most franchise agreements come with a required chart of accounts, because the franchisor compares every location on the same report. Keep the franchisor's account names and numbers, and add a mapping to the return line for each one. Three accounts are specific to a franchise:
Excite Tax's example: a St. George franchisee pays a $45,000 initial franchise fee in July 2025. Spread over 15 years, that is $3,000 a year, or $250 a month. Amortization starts in the month of acquisition, so 2025 gets six months, $1,500, and the balance sheet shows $43,500 left at December 31. A 6% royalty on $400,000 of sales, $24,000, is deducted in full that year.
Excite Tax's example: one week in the bank feed of a Utah County HVAC company run as a single-member LLC.
Categorizing one week (Schedule C lines)
| Transaction | Account | Where it lands |
|---|---|---|
| $1,850 to a parts supplier for a furnace install | Job materials | Part III line 38 |
| $2,400 to a subcontracted electrician | Subcontractors | Line 11, contract labor |
| $640 of fuel for the service vans | Vehicle fuel and repairs | Line 9 |
| $212 lunch with a builder about upcoming work | Meals | Line 24b, generally 50% deductible |
| $3,000 transfer to the owner's personal account | Owner draws (equity) | Nowhere: an owner's draw is not wages |
| $1,200 van loan payment: $1,050 principal, $150 interest | Van loan (liability) and interest expense | $150 on line 16b; the principal reduces the loan |
| $2,000 transfer from savings to checking | Transfer between the business's own accounts | Not income; nothing on line 1 |
Of the $9,302 that left checking that week, only $5,252 is a cost on Schedule C (materials, subcontractor, fuel, the meal before its deduction limit, and the interest). The other $4,050 is the owner's draw and loan principal, neither of them a deduction, and the $2,000 from savings is not income on line 1 at all. A bookkeeping app that guesses "expense" for every payment out would overstate the week's costs by more than three quarters.
For most small businesses, roughly one account per return line actually used, plus the balance-sheet accounts the bank, cards and loans require. Add a sub-account only when someone will read it: a restaurant wants food and beverage costs apart, a landscaper wants each crew's labor apart. Delete or merge an account that has held nothing for a year.
Never rename an account to change what it means mid-year. Close it and open a new one, so earlier months still add up to what was reported.
Two liability accounts matter most for a Utah business. Sales tax payable holds Utah sales tax collected from customers until it is paid over; the returns are TC-62S and TC-62M, filed electronically, and they are due the last day of the month after the filing period. Keeping the tax out of the sales account means the return can be filed straight from one balance.
Payroll liabilities hold income tax withheld from employees until it is paid. Utah TC-941E quarterly returns are due April 30, July 31, October 31 and January 31, so the account should return to zero after each one. A balance that keeps growing is a missed deposit, not a bookkeeping quirk.
A chart that grew by accident can be repaired without starting over. Map every existing account to a return line, merge those that share a line, mark the rest inactive, and reclassify the current year's transactions into the survivors. Fix messy books walks through the order, and common bookkeeping mistakes lists the categorizing errors that cause most of the mess. A brand-new business can start clean with bookkeeping for a new business.
Hand the books over when keeping them costs more hours than the business can spare, or when they stop agreeing with the bank.
Excite Tax keeps these books; the return they feed is reviewed and signed by a licensed CPA at TBD CPA LLC.
