How to Budget for Corporate Income Tax in Your Sri Lanka Company’s First Financial Year

Once your company starts generating revenue, management attention often goes to customer collections and payroll. Then, at year-end, the business may appear profitable—but no cash has been set aside for tax. A first-year corporate income tax budget is not about calculating one final tax number in advance. It is about identifying transactions that may affect the tax position, understanding when cash may come under pressure, and referring material questions to accounting and tax professionals early.

A common assumption is that corporate income tax can be budgeted by applying a tax rate to accounting profit. In practice, it is rarely that simple. Book profit, the basis used for tax purposes, the supporting documents available for costs, revenue recognition arrangements, and payments to related parties may all create differences. Treating accounting profit as tax profit can lead to more than an extra spreadsheet: you may be asked to retrieve documents, reclassify transactions, or find a cash shortfall after funds have already been committed to inventory, projects or expansion.

Set the right objective: early warning, not self-assessment

During the first financial year, it is useful to maintain two separate working files: an operating budget and a corporate income tax early-warning schedule. The operating budget answers whether the business is profitable. The tax schedule asks a different question: if the current transaction and documentation position continues through year-end, what items may require tax review, and will there be enough cash available at that point?

This schedule should not replace formal filings or professional advice. Its purpose is to help decision-makers see changes each month rather than leaving tax issues until the weeks before an audit.

You can structure the schedule using the following logic:

Area	Information to include in the budget	Questions for management
Revenue	Invoiced revenue, delivered but uninvoiced revenue, advance receipts, expected project revenue	Are the contracts, delivery records and invoicing status consistent?
Direct costs	Purchases, subcontracting, logistics and on-site project costs	Can each cost be linked to a contract, order, acceptance record or payment record?
People costs	Salaries, bonuses, expenses relating to secondees, recruitment and training	Are the employing entity, paying entity and actual beneficiary aligned?
Operating expenses	Rent, software, advisers, travel, marketing and administrative costs	Is the expense connected to the local business, and is its business purpose properly documented?
Related-party transactions	Group service charges, management fees, technical support charges, loan and interest arrangements	Are pricing, service descriptions, evidence of benefit and approval records retained?
Cash planning	Expected tax-related payment periods, available cash balance and head-office funding support	Has cash for tax been absorbed by inventory, equipment purchases or customer payment terms?

Start with revenue—do not look only at cash received

One of the most common forecasting errors is to treat money received in the bank as the only revenue figure. For businesses with staged contractual delivery, continuing services, installation work or project acceptance procedures, payment, invoicing, delivery and revenue recognition may occur at different times. A tax budget should not be built by finance alone from bank statements. It also needs input from sales, project teams and contract management.

When updating the forecast each month, consider separating revenue into four groups: completed and invoiced; completed but not invoiced; cash received but performance still outstanding; and amounts under dispute or pending acceptance. This is not intended to make an internal tax determination. It helps your appointed professionals understand the facts quickly and identify items that need further review.

Avoid information gaps where the contract is held by head office, delivery takes place in Sri Lanka, and payment is made to another entity. Once the transaction trail is fragmented, the local team may only see part of the payment or invoice record. Reconstructing the explanation at year-end can be difficult.

For costs, the key is the evidence—not only the amount

Including an expense in an operating budget is different from having sufficient support for that expense. In the first financial year, label costs as “documents available,” “documents pending,” or “business nature to be confirmed,” rather than treating every paid item as a cost ready to be used in a tax forecast.

For each significant category of expenditure, prepare a minimum evidence pack:

• Supplier contracts, quotations or purchase orders;
• Invoices, payment requests and bank payment records;
• Goods receipt, acceptance, service delivery or project-use records;
• Internal approvals and an explanation of business purpose;
• For head-office or related-party charges, service descriptions, charging basis and evidence of benefit.

Rent, professional services, travel, marketing activities and consultancy costs are particularly likely to involve a real payment but incomplete business documentation. Your budget should identify items with outstanding documents and assign a business owner. Do not assume finance should chase all missing records at year-end.

If you are preparing records ahead of an audit, you may also refer to the published article, How Sri Lanka Companies Can Organise Books, Contracts and Bank Records Before Their First-Year Audit. Audit preparation and corporate income tax budgeting are not the same exercise, but the approach to organising contracts, books, bank records and delivery evidence is closely related.

List related-party transactions separately—do not bury them in “management expenses”

When a group company charges the Sri Lanka company for management, technical, procurement support or other services, many teams enter only one total amount in the budget. That makes it harder to assess potential tax considerations and harder for both head office and the local company to explain what services the payment relates to.

A more practical approach is to list each transaction separately: payer and recipient, service scope, contractual basis, charging method, period incurred, supporting documents and payment plan. Where services are provided from outside Sri Lanka or payments involve cross-border arrangements, ask tax professionals to review the actual contracts and transaction facts early and identify matters that may require attention.

The common misunderstanding here is that a group’s internal approval means there can be no tax issue. In reality, an approval record only shows internal authorisation. It does not replace preparation of evidence on whether services were actually provided, whether the local company benefited, how the charge was priced, or whether documents are complete.

Use a rolling forecast for cash management, not a one-off year-end estimate

Update the corporate income tax early-warning schedule monthly or quarterly, and compare at least three views: the opening budget, the current forecast and a year-end scenario. The current forecast reflects transactions already completed and contracts already signed. The year-end scenario can include variables such as delayed customer collections, lower project margins, missing expense documentation or increased related-party service charges.

Management does not need to debate complex technical tax issues every time. It should, however, regularly review these questions:

1. Is the expected profit movement driven by revenue, costs or classification adjustments?
2. Which significant expenses still lack contracts, invoices or delivery evidence?
3. Are there related-party payments or head-office cost allocations not included in the budget?
4. Will cash over the next few months be sufficient for operating expenses and potential tax-related payments?
5. Which matters require professional input before signing a contract, making a payment or closing the year-end accounts?

When budget pressure increases, it is not advisable to “solve” the issue by delaying entries, changing transaction descriptions at short notice, or preparing contracts in bulk after the fact. A more reliable approach is to reflect the facts accurately, complete evidence for transactions that have already occurred, correct internal data, and confirm the next steps with your appointed accounting and tax professionals.

A workable monthly routine for the first financial year

After each month-end close, finance can consolidate revenue, costs, payroll, bank statements and payables. Sales or project owners can confirm contract progress, acceptance status and expected collections. Procurement and administration can provide business evidence for major expenses. Management can confirm new related-party transactions, head-office support and significant budget changes. Matters requiring judgement can then be compiled into a question list for review by appropriately qualified professionals.

You do not need to build an in-house system for interpreting tax law. You do need a factual recordkeeping system that allows professionals to assess the situation efficiently. In the first financial year, this is often more important than trying to arrive at a precise tax amount too early.
