How to Set Up a Chart of Accounts for a Small Business

Set up a chart of accounts for an Indian services SME: account groups, numbering, the right level of detail, GST and TDS ledgers, and a starter template.

11 min read

Short answer

To set up a chart of accounts, start with the five main groups: assets, liabilities, equity, income and expenses. Give each group a number range, then add only the ledgers you need to prepare your financial statements, file tax returns and run your monthly reports. Keep GST and TDS in separate ledgers by tax type and direction, and agree the final list with your chartered accountant before you post any entries. Last reviewed: November 2026.

What is a chart of accounts and why does its structure matter?

A chart of accounts is the list of every ledger your business posts to, arranged in groups. Each sale, purchase, payment and adjustment lands in one of these ledgers, so the list decides what your reports can show.

A well-planned chart makes month-end close quicker, keeps GST and TDS balances easy to reconcile against the portals, and gives your chartered accountant clean figures for the financial statements. A badly planned one usually turns into duplicate ledgers, a large miscellaneous expense account and hours of reclassification at year-end.

The structure should follow the financial statement format that applies to your entity. For a company this is the format your accountant uses for the Companies Act financial statements; for an LLP, partnership or proprietorship, confirm the expected presentation with your CA. Building ledgers that roll up into those headings saves remapping later.

Which account groups should you start with?

Use the five standard groups and place sub-groups under them. Sub-groups are headings, not ledgers: you post only to the ledgers underneath.

  • Assets: bank and cash, trade receivables, advances to suppliers and staff, input tax credit balances, TDS receivable, deposits, prepaid expenses and fixed assets.
  • Liabilities: trade payables, GST output and payable balances, TDS payable, salaries and other payables, customer advances, accrued expenses and borrowings.
  • Equity: share capital or partners' or proprietor's capital, and retained earnings or current account balances.
  • Income: revenue from services, split by line of service where that helps, and other income such as interest.
  • Expenses: direct costs of delivering services, employee costs, occupancy, technology, professional fees, finance costs, depreciation and other operating costs.

How should you number your accounts?

Give each main group its own block of numbers and leave gaps so you can add ledgers later without renumbering. A four-digit scheme suits most small businesses.

An example four-digit numbering scheme
RangeGroupExample sub-groups
1000–1999AssetsBank and cash, receivables, tax credits, fixed assets
2000–2999LiabilitiesPayables, GST and TDS payable, accruals, borrowings
3000–3999EquityCapital, retained earnings, drawings
4000–4999IncomeService revenue, other income
5000–5999Direct costsSubcontractors, project costs
6000–7999Operating expensesStaff, rent, software, professional fees
8000–8999Finance and non-cash costsInterest, bank charges, depreciation

Step numbers by 10 within a sub-group, so 1010, 1020 and 1030 rather than 1001, 1002 and 1003. Record the rule in a short note so anyone adding a ledger follows the same pattern.

How much detail should the chart have?

Add a ledger only when a decision, a return or a statutory disclosure needs that figure separately. If nobody will review a balance on its own, it probably belongs in a broader ledger.

  • Create a separate ledger when the amount is reported separately in the financial statements or a tax return.
  • Create one when it needs its own reconciliation, such as each bank account, each loan or each tax balance.
  • Use customer and vendor sub-ledgers or party records instead of a general ledger for every customer or supplier.
  • Use cost centres, projects or tags for analysis by client, team or location rather than multiplying ledgers.
  • Keep miscellaneous expenses small and review it monthly; reclassify anything that recurs.

Many services SMEs work well with somewhere between a few dozen and around a hundred active ledgers. Treat that as a rough guide rather than a target; the right number depends on how many bank accounts, registrations and service lines you run.

How should you set up GST ledgers?

Keep GST separate by tax type and direction. Output tax collected on sales and input tax credit on purchases should never sit in the same ledger, because each is reconciled against a different return or statement on the GST portal.

  • Output tax ledgers for CGST, SGST or UTGST and IGST.
  • Input tax credit ledgers for CGST, SGST or UTGST and IGST.
  • Reverse charge ledgers, kept separate, for tax you pay on inward supplies under reverse charge.
  • A GST cash ledger or GST payable clearing ledger for amounts deposited and set off, if your accountant prefers that method.
  • An ITC on hold or ITC under review ledger for credit you are not yet ready to claim.
  • Interest and late fee ledgers for GST, recorded as expenses and not mixed with tax.

If you hold GST registrations in more than one state, set up the GST ledgers per registration (per GSTIN) so each can be reconciled on its own. Which tax heads apply, and how reverse charge and credit restrictions work for your supplies, depends on current GST law; confirm with your CA and the GST portal rather than relying on a template.

How should you set up TDS ledgers?

TDS appears on both sides of a services business. Tax you deduct from vendor or salary payments is a liability until you deposit it; tax your customers deduct from your invoices is an asset until it is matched and claimed in your income tax return.

  • TDS payable ledgers, one for each type of payment you regularly deduct on, such as contractor payments, professional fees, rent and salaries.
  • TDS receivable ledgers for tax customers deduct from your invoices, with one ledger for each financial year so old balances stay visible.
  • Interest on late TDS payment, recorded as an expense in its own ledger.

Splitting TDS payable by type of payment makes it easier to tie the ledger to your challans and TDS returns. Which payments attract TDS, the applicable sections and the current rates change from time to time; check the Income Tax portal or ask your CA when setting up deduction rules. The guide on TDS compliance for startups and MSMEs covers the process in more detail.

What does a starter chart of accounts look like for a services SME?

The template below is a starting point for a single-state services business registered under GST. Remove ledgers you do not need, and add others only when the detail rules above call for them.

Whether an item such as interest on late tax payment is deductible, or which headings your statements must show, is a question for your CA. The template organises the books; it does not decide tax treatment.

What should you check before going live?

  1. Map every ledger to a financial statement line and have your CA review the mapping.
  2. Confirm GST ledgers match your registrations and the tax heads you actually charge and claim.
  3. Confirm TDS payable ledgers match the payment types you deduct on.
  4. Write a one-page note on numbering, naming and who may create new ledgers.
  5. Load opening balances and tie them to the last signed trial balance; the guide on verifying opening balances after an accounting software migration explains this step.
  6. Run a test month and confirm the reports you need come out without manual regrouping.

Once the chart is live, design your monthly reporting around it. The monthly finance dashboard guide for startups shows how ledger groups feed the figures owners review each month.

What common mistakes should you avoid?

  • Creating a ledger for every customer and supplier instead of using party records.
  • Combining input and output GST in one ledger, or mixing CGST, SGST and IGST.
  • Posting GST interest or late fees to the tax ledgers.
  • Leaving TDS deducted by customers sitting on the customer account.
  • Letting several people create ledgers freely, which produces near-duplicates such as two internet expense accounts.
  • Renaming a ledger to mean something different mid-year, which breaks comparisons.
  • Copying a trading or manufacturing template with inventory and purchase ledgers a services business will never use.

This guide suits a services business with straightforward operations. Businesses holding inventory, operating in several states, receiving foreign currency at scale or applying Ind AS will need additional ledgers and should design the chart with their CA from the start.

    Questions owners ask

    How many ledgers should a small services business have?

    Enough to prepare your financial statements, reconcile each bank, loan and tax balance, and produce the reports you review. Use party records, cost centres and tags for further analysis rather than adding ledgers.

    Should I create separate GST ledgers for each state?

    If you hold more than one GST registration, keep separate GST ledgers for each registration so each can be reconciled with its own returns. Confirm the setup with your CA.

    Can I change my chart of accounts after I start posting?

    Yes, but add new ledgers rather than repurposing old ones, and make structural changes at the start of a period where possible. Record the change and reclassify past entries only after review with your accountant.

    Where should TDS deducted by my customers go?

    Post it to a TDS receivable ledger for the relevant financial year, not to the customer account, and match it with the tax credit statement before filing your income tax return.
