Non-Deductible Business Expenses in Sri Lanka: The Complete 2025/26 List
Not everything your company spends money on reduces its tax bill. The Inland Revenue Act No. 24 of 2017 draws a hard line between expenses that are tax deductible and those that must be added back when calculating taxable profit. This guide lists every category of non-deductible (disallowed) expense, explains the famous grey areas — including whether a car lease is deductible — and gives you a clear deductible vs non-deductible comparison table, so you can separate them like an accountant would.
1. The golden rule: "in the production of income"
Section 11 of the Inland Revenue Act allows a deduction only for expenses "incurred during the year… in the production of income" from the business. Two tests flow from this single sentence:
- Purpose test — the expense must exist to earn the company's income. Rent for the shop, staff salaries, raw materials, business internet: deductible. Anything spent for a person's private benefit fails the test.
- Capital test — even a genuine business expense is not deductible outright if it is capital in nature. The Act says an expense is capital if it "secures a benefit capable of lasting longer than twelve months". A machine, a vehicle, a building or major software isn't "used up" in the year — so it is relieved gradually through capital allowances (tax depreciation) instead of a one-off deduction.
2. The full list of non-deductible expenses (section 10)
Section 10(1)(b) of the Act then lists expenses that are never deductible, no matter how business-related they feel. When computing taxable profit, each of these must be added back to accounting profit:
| # | Disallowed expense | What it covers in practice |
|---|---|---|
| 1 | Domestic (personal) expenses | Anything for a person's private benefit — meals, grooming, commuting, ordinary clothing, personal debts. See the haircut rule below. |
| 2 | Income tax itself | Tax payable under the Inland Revenue Act is not a deductible cost of the business. |
| 3 | Fines & penalties | Interest, penalties and fines payable to any government (Sri Lankan or foreign) for breach of any written law — traffic fines, late-payment penalties, EPF/ETF surcharges. |
| 4 | Costs of earning exempt income | Expenditure incurred in deriving exempt amounts or final withholding payments. |
| 5 | Non-approved retirement contributions | Retirement contributions are deductible only if included in the employee's taxable income or paid to a pension/provident/savings fund approved by the Commissioner-General. |
| 6 | Dividends | Distributions of profit to shareholders are not an expense of earning profit. |
| 7 | Entertainment 🚫 | Outlays or expenses for entertainment — client dinners, parties, hospitality, gifts of entertainment. Expressly disallowed even though genuinely business-related. |
| 8 | Reserves & provisions | Amounts transferred to reserves, or provisions for expected future expenses or losses (e.g. a general bad-debt provision). Only actual, incurred costs count. |
| 9 | Gambling & lottery losses | Outlays on lotteries, betting or gambling — unless that is the company's business. |
| 10 | Taxes/levies specified by the CGIR | Any tax or levy the Commissioner-General of Inland Revenue specifies as non-deductible. |
3. Personal & domestic expenses — the "haircut rule" (section 197)
The most common mistake small-company owners make is running personal life through the company. Section 197 defines "domestic expenditure" very widely — all of it non-deductible:
- ✂️ Personal upkeep — costs of maintaining yourself, including shelter, meals, refreshment, entertainment and leisure. Yes, that includes the director's haircut, gym membership and family groceries — even if you "need to look professional for clients".
- 🚗 Commuting — travel between home and work. (Travel between business locations or to visit a customer is business travel and deductible.)
- 👔 Ordinary clothing — clothes and shoes you could wear outside work. Only clothing not suitable for wearing outside of work (branded uniforms, safety boots, protective gear) is deductible.
- 🎓 General education — courses are non-deductible unless directly relevant to the business and not leading to a degree or diploma. (Job-specific staff training is deductible.)
- 💳 Personal debts — paying the owner's personal loans or credit card bills from company money is never a business expense.
4. Deductible vs non-deductible: side-by-side table
Here is how everyday Pvt Ltd expenses split, with the reason for each. "Partly" means the expense must be split or has conditions.
| Expense | Deductible? | Why |
|---|---|---|
| Office / shop rent | ✔ Yes | Incurred in the production of income (s. 11). |
| Staff salaries & EPF/ETF contributions | ✔ Yes | Production of income; EPF/ETF are approved funds. |

| Finance lease on a van / lorry / bus | ◐ Split | Interest portion deductible; capital portion via capital allowances — commercial vehicles qualify (Fourth Schedule). |
| Finance lease on a passenger car (e.g. director's sedan) | ◐ Interest only | Interest portion deductible, but capital allowances are denied for passenger cars — capital portion effectively non-deductible. See below. |
| Service fee where WHT was withheld but not yet paid to IRD | ◐ Deferred | No deduction until the withheld tax is paid to the IRD (s. 10(2)). |
5. Is a car lease tax deductible in Sri Lanka?
This is the question every new company director asks — and the answer is more subtle than "yes" or "no". Three rules interact:
Rule 1 — a finance lease is treated as a loan (s. 31)
If your lease is a finance lease (ownership passes at the end, or you have a purchase option — the typical Sri Lankan vehicle lease), the Act does not treat the monthly rental as a simple expense. Each payment is split into:
- Interest — deductible under the normal interest rules (s. 12), and
- Capital repayment — not deductible as an expense. The lessee is treated as the tax owner of the vehicle (s. 49), so the capital cost must instead be claimed through capital allowances.
Rule 2 — passenger cars get no capital allowances (Fourth Schedule)
Here is the sting. Paragraph 2(4) of the Fourth Schedule says no capital allowance shall be granted for a road vehicle unless it is:
- a commercial vehicle — designed to carry loads over half a tonne or more than 13 passengers, or a vehicle used in a transportation or vehicle-rental business;
- a bus or minibus;
- a goods vehicle (lorry, truck); or
- a heavy general-purpose or specialised truck or trailer.
An ordinary passenger car — the director's sedan, SUV or hatchback — is none of these. So on a finance-leased car, only the interest slice of each rental is deductible; the capital slice gets no relief at all. On a leased van, lorry, bus or a car used in a taxi/rental fleet, both slices get relief (interest as expense, capital via 5-year allowances).
Rule 3 — genuine operating rent is different
If the company merely rents/hires a vehicle short-term (no ownership transfer, no purchase option) and uses it for business, the hire charge is an ordinary deductible expense under s. 11 — for the business use.
6. Capital expenses & depreciation (capital allowances)
Capital purchases are not "lost" deductions — they are spread out. The Fourth Schedule grants straight-line capital allowances:
| Class | Assets | Write-off period |
|---|---|---|
| 1 | Computers & data-handling equipment | 5 years (20%/yr) |
| 2 | Buses, minibuses, goods vehicles; construction & earth-moving equipment; heavy trucks; plant & machinery used in manufacturing | 5 years (20%/yr) |
| 3 | Railroad assets, vessels, aircraft, office furniture, fixtures & equipment, and any other depreciable asset | 5 years (20%/yr) |
| 4 | Buildings, structures & similar works of a permanent nature | 20 years (5%/yr) |
| 5 | Intangible assets (software, licences) other than goodwill | Over actual useful life (20 yrs if indefinite) |
- Passenger cars: as explained above, road vehicles other than commercial vehicles, buses/minibuses, goods vehicles and heavy trucks get no capital allowances at all.
- Repairs vs improvements (s. 14): repair costs are deductible only up to 5% of the asset's written-down value per year for buildings (Class 4) and 20% for other assets; the excess is added to the asset's cost and depreciated.
- R&D and agricultural start-up costs (s. 15): deductible in full even if capital in nature — a deliberate incentive.
7. Grey areas & special rules accountants watch
- Mixed-use expenses: a phone or internet connection used for both home and business is deductible only to the extent it is used in producing income — apportion it and keep the basis on file.
- Paying personal costs as taxed salary: under s. 197(2), a personal benefit becomes deductible for the company if it is included in the employee's taxable pay. Many "disallowed" items can be restructured this way — with APIT consequences for the individual.
- Thin capitalisation (s. 18): if the company is heavily debt-funded by related parties, interest deductions are capped relative to share capital and reserves (roughly 3:1 for manufacturers, 4:1 for others); the excess carries forward.
- WHT precondition (s. 10(2)): deductions requiring withholding are frozen until the WHT is actually remitted.
- Documentation: even a perfectly deductible expense fails on audit without evidence. Keep the invoice/receipt for every entry — a photo attached to the record is enough to start with.
8. How to track non-deductible expenses without a spreadsheet war
The practical problem is bookkeeping: your accounting profit needs every expense, but your taxable profit must exclude the disallowed ones. Doing that at year-end from a shoebox of receipts is where mistakes happen.
TaxBook.lk (free, English & Sinhala) solves it with a single tick: record every expense as it happens, and tick "Not deductible" on the ones in this guide — entertainment, fines, personal items, passenger-car lease capital. Ticked expenses show in amber, and the app automatically:
- keeps them in your P&L (accounting profit), but
- adds them back for the tax estimate, so your corporate-tax figure is computed on deductible expenses only, and
- shows the add-back line on your financial statement and CSV export — exactly what your accountant and the IRD return need.
Separate deductible from non-deductible — automatically
Log expenses, tick the non-deductible ones, and see your true taxable profit and tax estimate live. Free, in Sinhala & English.

What business expenses are not tax deductible in Sri Lanka?
Under section 10 of the Inland Revenue Act No. 24 of 2017: personal/domestic expenses, income tax itself, fines and penalties payable to a government, costs of earning exempt income, dividends, entertainment, transfers to reserves or provisions, gambling losses (unless gambling is the business), non-approved retirement contributions, and taxes specified by the Commissioner-General. Capital expenses are also not deductible outright — they get capital allowances instead.
Is a car lease tax deductible in Sri Lanka?
It depends on the vehicle and lease type. A finance lease is treated as a loan (s. 31): the interest portion is deductible, but the capital portion needs capital allowances — and the Fourth Schedule denies allowances for road vehicles other than commercial vehicles, buses/minibuses, goods vehicles and heavy trucks. So for an ordinary passenger car the capital portion is effectively non-deductible, while a van, lorry or bus qualifies fully. Genuine short-term hire of a vehicle for business use stays deductible.
Are entertainment expenses deductible?
No. Section 10(1)(b)(vii) expressly disallows outlays or expenses for entertainment — client dinners, parties and hospitality must be added back even though they are genuine business costs in an accounting sense.
Are fines and penalties tax deductible?
No. Interest, penalties and fines payable to any government for breach of any written law are non-deductible (s. 10(1)(b)(iii)) — traffic fines, late-payment tax penalties and EPF/ETF surcharges included. Income tax itself is also non-deductible.
Can the company deduct my haircut, meals or clothes as a director?
No — these are "domestic expenditure" under section 197: grooming, meals, refreshment, leisure, home-to-work commuting, ordinary clothing wearable outside work, and personal debts/credit cards. The exception: if the amount is taxed in your hands as salary or a benefit, the company can generally deduct it as staff cost.
Are capital expenses like machinery, vehicles or buildings deductible?
Not immediately. Anything securing a benefit lasting longer than twelve months is capital (s. 11) and is relieved through Fourth Schedule capital allowances instead — computers 5 years, plant/machinery and commercial vehicles 5 years, buildings 20 years, intangibles over useful life.
What happens if I claim a non-deductible expense in my return?
Disallowed items must be added back to taxable profit. If the IRD finds them claimed on audit, it can assess the underpaid tax plus penalties and interest. Flagging them in your books as you go — for example with TaxBook.lk's non-deductible tick — makes the add-back automatic.
Are staff meals, travel or training ever deductible?
Yes — business travel (not commuting), job-relevant staff training, uniforms/safety wear not suitable outside work, and any benefit that is taxed in the employee's hands are all deductible because they are incurred in the production of income.
