Lost Receipts? What You Can Still Claim in Sri Lanka

You're pulling together your return and the receipts aren't there. Maybe they faded, maybe they went out with an old laptop bag, maybe they never made it out of the shop. Now you're wondering whether those expenses are simply gone.

Some of them are. Many aren't. The difference comes down to one question the law actually asks, and it isn't "do you have the receipt?" This guide covers what a lost receipt means for your tax deduction in Sri Lanka, which substitutes carry weight, and which gaps aren't worth chasing.

Can you still claim an expense if you lost the receipt?

Yes, in principle. The main deduction rule for business and investment income is short.

That's the whole test. Was the expense incurred during the year, and was it incurred to earn your income? Nothing in it mentions a receipt, an invoice, or any other named document. We couldn't find any provision in the Act that makes a particular piece of paper a condition of deduction.

But don't read that as "no receipt, no problem." Section 10(3) says "No deduction shall be allowed except as expressly permitted by this Act," so the expense still has to fit Section 11(1) or another deduction provision. And someone has to show it does. That someone is you.

So the deduction doesn't disappear with the paper. It disappears if you can't prove the expense happened and was for the business.

Who has to prove the expense was real?

You do. The Act is blunt about it.

Here's how that plays out. Say the Department reviews your return and doesn't accept a Rs. 300,000 expense. Under Section 135(1), an Assistant Commissioner can amend your assessment "based on such evidence as may be available and to the best of his judgement." If the only evidence available is your word, their judgment is unlikely to include the expense.

If you object or appeal, Section 141 means you have to show the amended assessment is wrong. The Department doesn't have to prove you didn't spend the money. That's why a lost receipt matters. It isn't a legal bar to the deduction. It's missing ammunition for an argument you may one day have to win.

If you do end up disputing an assessment, our guide to appealing a tax assessment in Sri Lanka walks through the process.

What evidence can stand in for a lost receipt?

More than most people assume. The Act lists what counts as a source document, and receipts aren't even named.

Our tax record keeping guide covers how long to keep all of this and the penalty for not keeping it. What matters here is that list. It's broad, and it ends with "other documents which relate to an element of a transaction." A receipt is just one of many things that can prove an expense.

Not all substitutes are equal, though. Here's roughly how they rank when you're rebuilding a missing record.

Notice the pattern. The strong entries come from a third party: the bank, the supplier, the client. They existed before anyone questioned you, so they're hard to fake. The weak entry is the one you create after the fact.

Where does reconstruction end and guessing begin?

The Act doesn't draw this line for you. There's no rule saying "a statement plus an email is enough" or "estimates are acceptable up to Rs. X." Section 120(1) sets an outcome standard: records "sufficient to record all transactions and to ascertain the gains and profits made or the loss incurred." That's it.

So the line is practical rather than statutory, and it runs roughly here.

Reconstruction means rebuilding a record from traces that already exist. You find the Rs. 45,000 payment to a web host on your card statement, pull the renewal email from your inbox, and write up a note tying the two together. Every number in it came from somewhere you can point to.

Guessing means inventing a figure. "I probably spent about Rs. 15,000 a month on client travel." There's no statement entry, no booking, nothing. If an Assistant Commissioner is working "to the best of his judgement" under Section 135(1), a number with no trace behind it gives them nothing to accept.

There's a sharper risk too. Putting a made-up figure on a return is how an honest gap becomes a negligence problem. More on that below.

Timing matters too. If the Commissioner-General formally requires a document from you under Section 122 or 123 and you don't provide it, Section 122(8) says you can't later use that document in a judicial proceeding challenging the assessment, unless the Commissioner-General agrees. So do the rebuilding before anyone asks, not after.

Does it matter if it was a big asset or a small recurring cost?

Yes, and in two ways that catch people out.

Capital items stretch across years. Section 11(2) says no deduction is allowed under Section 11(1) for "an expense of a capital nature," and Section 11(3) says that includes "an expense that secures a benefit capable of lasting longer than twelve months." A laptop, a camera, office furniture: these aren't deducted in the year you buy them. They're written off through capital allowances under the Fourth Schedule. Computers fall into Class 1, spread over five years.

So a lost invoice for a Rs. 600,000 laptop isn't one weak claim. It's the cost behind roughly Rs. 120,000 of allowances in each of five returns. And because Section 120(6)(b) makes you keep records "until expiration of the time limit for assessment of tax for any tax period to which the records are relevant," that one invoice stays relevant well past five years from the purchase. It's worth real effort to replace.

Small recurring costs are forgiving in bulk, fragile one by one. Your monthly internet bill is the opposite case. Lose one month's bill and eleven others, plus a year of identical debit orders on your bank statement, make the missing month easy to explain. Lose every bill for a cost you paid in cash and there's nothing to reconstruct from at all.

Large cash payments are a different problem entirely. If the missing receipt is for a large payment made in cash, check the cash rule before spending time on evidence. Section 10(2A) disallows a deduction for cash payments above its limit, and says the amount "shall not be considered as cost of an asset" either. That's a rule about how you paid, not about proof, so no amount of reconstruction rescues it. Our guide on cash expense deductions covers the threshold and the exceptions.

What happens if the deduction is later disallowed? (worked example)

Here's the real cost, using the Year of Assessment 2025/2026 rates.

Nimali is a graphic designer working for local clients. After her Rs. 1,800,000 personal relief, her taxable income is Rs. 2,700,000. Among her claims is Rs. 200,000 of printing and courier costs, mostly paid in small cash amounts, with no receipts and nothing on her bank statement.

An Assistant Commissioner doesn't accept the Rs. 200,000, and Nimali has nothing to show under Section 141.

Rs. 200,000 of lost deductions costs Rs. 72,000 in tax, because every rupee of it sat in the 36% band.

Then come two more layers.

Interest. Section 157(1) charges interest on tax not paid by the due date, and Section 157(2) says that for a revised assessment the due date is "the original due date of the tax." Section 159(1) sets the rate at "one and one-half per cent per month or part month." On Rs. 72,000 that's about Rs. 1,080 for every month since the original due date. The Minister can vary the rate by Gazette order under Section 159(3).

A possible penalty. Section 180 applies only where the incorrect statement is "a result of intentional conduct or negligence on the part of the taxpayer." If it applies, the penalty is 25% of the underpayment, here Rs. 18,000. It rises to 75% if the underpayment exceeds Rs. 10 million or 25% of the tax liability for the period. Nimali's Rs. 72,000 is well under 25% of Rs. 564,000, so 25% would be the ceiling for her.

One point in your favour. Section 176(4) says "the burden of proof shall be on the Commissioner General to show non-compliance with the provisions of this Act with respect to the imposition of a penalty." So you have to prove the expense, but the Department has to prove the negligence behind any penalty. An honest claim with a lost receipt is a very different position from a fabricated one.

Which missing records are worth chasing?

Some gaps are worth an afternoon of emails. Some aren't worth the phone call. Here's a practical triage.

Chase these first:

• Invoices for capital items like computers, equipment, and furniture. One document supports up to five years of allowances.
• Anything large. The tax at stake scales with the amount, and a large disallowance can cost more than a small one's penalty and interest combined.
• Anything a third party can resend. Suppliers keep copies. Online platforms keep order histories. Your bank keeps statements, though not forever, so download them now.
• Contracts and engagement letters for services you paid for. They supply the business purpose a bank entry can't.

Probably let go:

• Small cash purchases with no trace anywhere. A Rs. 1,200 stationery run paid in cash, with no statement entry and no email, can't be reconstructed. Claiming it anyway on a guessed figure risks more than it saves.
• Costs you can't tie to the business. If you can't show the purpose now, you won't be able to show it later either.

Being honest about what's unrecoverable is part of the job. The goal is a return you can defend line by line, not the biggest number you can put on it. If you're unsure whether a cost qualifies at all, our guide to what expenses freelancers can deduct is a good starting point.

How do you stop this happening next year?

The fix is timing. A receipt is easy to keep on the day you pay and hard to find ten months later. Nobody loses a receipt because they're careless in March. They lose it because nothing asked for it in June.

So, can you claim an expense after losing the receipt? Often, yes. The law asks whether you incurred it to earn your income, not whether you kept a particular slip of paper. But the burden of proving it is yours. Rebuild what you can from third-party traces, let go of what you can't, and never fill a gap with a guess.
