How to Use Cost Centres in Tally Prime (2026)

If you want to know how much a specific department, project, or branch is actually costing you — not just your overall expense total — Cost Centres in Tally Prime let you tag every transaction with that extra layer of detail. Instead of just seeing “Salaries: ₹5,00,000,” you can see exactly how that splits across departments or projects.

This guide covers setting up cost centres and categories, tagging transactions correctly, and the reports that make the setup worthwhile.

What You Need Before You Start

• Tally Prime installed, with your company already created
• A clear idea of how you want to split your business — by department (Sales, Marketing, Production), by project, by branch/location, or a combination of these

Step 1: Enable Cost Centres

1. Gateway of Tally, then F11 (Features), then F1 (Accounting Features)
2. Set Maintain Cost Centres to Yes
3. If you need more than one way of splitting transactions at once (for example, both department and project), also set Maintain More Than One Payroll/Cost Category to Yes
4. Press Ctrl+A to save

Step 2: Create Cost Categories (If You Need More Than One Split)

Cost Categories let you apply more than one independent classification to the same transaction — for example, tracking by department and by project at the same time, without one depending on the other.

1. Gateway of Tally, then Accounts Info, then Cost Categories, then Create
2. Name the category (for example, “Departments” or “Projects”)
3. Decide whether cost centres under this category allow Revenue Items, Capital Items, or both
4. Save

If you only need one type of split, you can skip categories and just create cost centres directly under the default category.

Step 3: Create Cost Centres

1. Gateway of Tally, then Accounts Info, then Cost Centres, then Create
2. Name the cost centre (for example, “Sales Department,” “Project Alpha,” or “Chandigarh Branch”)
3. Assign it to the relevant Cost Category if you created more than one
4. You can also create sub-cost-centres under a parent if you need a hierarchy, for example branches under a region
5. Save

Step 4: Mark Ledgers as Cost Centre Applicable

Not every ledger needs cost centre tracking — typically you’ll apply it to expense and income ledgers where the split actually matters, not to balance sheet items like bank or capital accounts.

1. Open the relevant ledger (for example, “Salaries” or “Advertising Expense”)
2. Confirm Cost Centres are Applicable is set to Yes for that ledger
3. Save

Step 5: Allocate Transactions to Cost Centres

Once set up, Tally Prime prompts for cost centre allocation whenever you use a cost-centre-applicable ledger in a voucher:

1. Record the voucher as usual (payment, purchase, journal, etc.)
2. When you reach the relevant ledger line, Tally Prime asks you to select a Cost Centre (and Cost Category, if applicable)
3. If the amount needs to be split across more than one cost centre, allocate the amount proportionally across each one
4. Save

Example: A ₹60,000 advertising expense covers both your Sales Department and Marketing Department. Instead of recording it as one lump expense, you allocate ₹40,000 to Sales and ₹20,000 to Marketing within the same voucher.

Step 6: Review Cost Centre Reports

1. Gateway of Tally, then Display More Reports, then Statements of Accounts, then Cost Centres
2. Review the Cost Centre Summary to see income and expense totals by cost centre over a selected period
3. Use Cost Centre Breakup for a specific ledger to see how that one expense or income line splits across all your cost centres
4. Compare cost centres against each other to spot which departments, projects, or branches are running over or under expectations

Common Mistakes to Avoid

• Marking every single ledger as cost-centre-applicable, including balance sheet items where the split doesn’t add useful information, just extra clicks on every voucher
• Inconsistent cost centre naming across different staff entering data, splitting what should be one cost centre into several similarly-named ones
• Forgetting to allocate cost centres on journal entries, which often get rushed through without the same care as routine sales/purchase vouchers
• Not deciding on a clear allocation method (square footage, headcount, percentage) for shared costs before recording them, leading to inconsistent splits over time
• Setting up cost centres but never actually reviewing the reports, which defeats the purpose of tracking the detail in the first place

FAQs

What’s the difference between a Cost Centre and a Cost Category? A Cost Centre is the specific unit you’re tracking (a department, project, or branch). A Cost Category is used when you need more than one independent way to classify the same transaction at once, such as both department and project.

Can I use cost centres without enabling multiple cost categories? Yes. If you only need one type of split, you don’t need to create cost categories at all — cost centres work fine under the default category.

Do I need to allocate every transaction to a cost centre? Only for ledgers you’ve marked as cost-centre-applicable. Balance sheet items like bank accounts typically don’t need this level of detail.

Can I see profit and loss by cost centre, not just expenses? Yes, as long as both income and expense ledgers relevant to that cost centre are marked as applicable and allocated correctly, you can view a cost-centre-wise breakdown that approximates a departmental or project profit and loss.

How is this different from using separate companies for each branch or project? Cost centres let you track detail within a single set of books, which is simpler for consolidated reporting. Separate companies make sense when branches or projects need entirely independent books, for legal or operational reasons.
