Tax-deductible expenses for a Cyprus company: what counts, what doesn't, and the proof you need

A Cyprus limited company can deduct an expense from taxable profit when three things are true. The company incurred it wholly and exclusively in the production of its income. The law doesn't disallow it by name. And a document proves it. Salaries, rent, software, professional fees, travel and marketing pass that test for almost every trading company. Private spending, fines, general provisions and entertainment above the cap don't. This guide covers the test, what falls on each side of the line, and the records that make a deduction hold up when someone checks it years later.

What makes an expense deductible in Cyprus?

An expense is deductible when the company incurred it wholly and exclusively in the production of its income. That's the rule in article 9(1) of the Income Tax Law. "Wholly" means the whole amount was for the business. "Exclusively" means no private motive was mixed in. An expense that serves both, like the family car that doubles as the company car or a phone plan shared with the household, fails as a whole. Only the part you can attribute to the business survives, and only if you can attribute it at all.

Mind the exact wording. The law says "in the production of income", which is narrower than "for the business". A cost with no link to earning the company's income can fail even when it was plainly a company decision.

Two more conditions apply. Article 11 must not disallow the expense by name. And it needs evidence, meaning an invoice or receipt showing who supplied what, when, for how much, and to the company. The Tax Department treats a real business cost with no paper behind it as private, because paper is what an inspector can examine.

Which expenses does a Cyprus company usually deduct?

These pass the test for almost every trading company, because each one is plainly spent to earn the company's income.

• Salaries, bonuses and employer contributions. Gross pay for employees and directors, plus the employer's Social Insurance, GeSY and fund contributions on it. GeSY is Cyprus's General Healthcare System. Salary versus dividends explains why a director's salary is a company expense, while a dividend is a share of profit paid out after tax.
• Rent and premises. Office rent, utilities and running costs. A home office is a mixed cost and needs a split you can defend.
• Software and subscriptions. Cloud tools, licences, hosting, accounting software. Many come from abroad with no VAT on the invoice. They're deductible for income tax either way, but read our guide to reverse-charge VAT for what the VAT return needs.
• Professional fees. Accounting, audit, legal and consultancy fees for the business. Fees for buying a capital asset, or for forming the company itself, are capital and follow the asset instead.
• Travel and subsistence. Flights, hotels and transport for a business trip. The private extension of the trip stays out, and the records themselves should show the business purpose.
• Marketing and advertising. Campaign spend, agency fees, website costs, trade shows.
• Equipment through capital allowances. Machines, computers, commercial vehicles and furniture get tax relief over time, not in the year you buy them. The tax computation adds back accounting depreciation and replaces it with wear-and-tear allowances at yearly rates set by law. Your accountant applies the rate. Your job is to have the purchase invoice.
• Interest and bank charges on borrowing used in the business. Specific restrictions apply where the money bought private assets or funded other companies.

Bad debts written off, donations to approved bodies and contributions to approved funds are also deductible, each under its own conditions.

Which expenses are not deductible?

An expense isn't deductible when it fails the purpose test, or when article 11 disallows it by name. Most disputes are about these groups.

• Private and mixed-use expenses. Anything for the director personally, such as groceries, family travel, a personal phone or clothing that isn't a uniform. Also the private share of anything mixed.
• Private saloon car costs. Article 11(13) expressly disallows the expenses of a private motor vehicle. The same goes for interest on borrowing that paid for one, for seven years from when it was bought. This catches many founders who buy the car through the company expecting a full deduction.
• Entertainment above the cap. Hospitality for clients and prospects is deductible only up to the lower of 1% of gross income and €30,000 from tax year 2026. Up to tax year 2025 the ceiling was €17,086. The excess goes back into taxable profit, and you generally can't reclaim the VAT you paid on entertainment either.
• Fines, penalties and interest on late tax. These are the cost of breaking a rule, not of earning income, so the law keeps them out.
• General provisions and unrealised amounts. A provision for doubtful debts that doesn't name specific debts, an accrual for a cost that may never arise, unrealised exchange differences on certain balances. The accounts may carry them. The tax computation adds them back.
• Capital expenditure and formation costs. You get relief on an asset's price through capital allowances, not as an expense. Incorporation fees are capital with no allowance at all, which surprises many founders in year one.

A loss left after all of this carries forward against future profits for seven years from tax year 2026. The 2026 reform extended it from five. In practice, 2019 losses, which would otherwise have expired, can still be set against 2026 profits. Losses from 2018 and earlier stay expired.

Can a company deduct costs from before it was incorporated?

Only under the same test, and often not at all. Cyprus income tax law has no special window for costs from before incorporation. The same article 9(1) rule decides, and start-up costs of a capital nature aren't deductible, incorporation fees included.

A running cost from shortly before the certificate arrives is different, if it's for the trade the company then actually carries on. Think of a software subscription, or advice on the first client contract. You claim it on ordinary principles, with the same documents as any other expense. Our article on pre-establishment expenses in Cyprus goes through the common categories one by one.

VAT is a different story, because VAT really does have look-back windows. On its first return, a newly registered company can reclaim input VAT, the VAT it paid to suppliers, on services received up to 6 months before registration, and goods bought up to 3 years before if it still has the goods. The two tests run separately. An expense can be deductible for income tax but fall outside the VAT window, or the reverse.

What evidence does the Tax Department expect?

A valid document for every entry, which you can produce on request. That means the supplier's invoice or receipt, addressed to the company, showing the supplier's details, the date, what was supplied, the amount and any VAT charged. Our guide to Cyprus invoice requirements lists what a compliant invoice contains. The same list is what makes a supplier's invoice usable as your evidence. Proof of payment supports the invoice, but doesn't replace it.

If the supplier's document is missing, follow what to do about a lost business receipt. It explains how to recover the document and keep the payment traceable, with income tax and VAT evidence assessed separately.

The standard is stricter than most founders expect. A card statement line naming an online retailer proves you paid, but says nothing about what you bought or why. A receipt in a director's personal name is weaker than one addressed to the company. And a purpose that's obvious to you in March won't be obvious to an inspector years later, unless the record says so.

The law sets the timeline too. Books must be written up by the end of the fourth month after the month of the transaction. You keep records for at least six years, counted from the later of the return's filing deadline and the date you actually filed it. For a company, that's about seven and a half years from the transaction. An audit trail from each ledger entry back to its source file lets your accountant, your auditor or the Tax Department confirm a deduction in seconds. Our year-end checklist shows how much closing work disappears when you keep records this way all year.

Why does the corporate tax return depend on this?

Because the tax computation is your accounting profit, adjusted by exactly these rules. Corporate income tax is 15% from tax year 2026, with 12.5% still applying to 2025 and earlier years. The base is accounting profit, plus every disallowed or unsupported expense, minus items the accounts treated differently. Capital allowances replacing depreciation is the usual example. The categories above are the add-backs and deductions on the face of the return. A clean expense ledger with documents attached makes the computation short. A messy one turns every line into a question.

Equipment and other fixed assets need their own calculation. Read capital allowances in Cyprus for the difference between accounting depreciation and the tax deduction, including the records you need when you sell an asset.

Timing matters as much as the rate. From tax year 2026, the corporate return is due by 31 January of the second year after the tax year. So the 2026 return is due by 31 January 2028, while the 2025 return keeps its 31 March 2027 deadline. Long before that, the company estimates its taxable profit for provisional tax, paid in two instalments on 31 July and 31 December of the year itself. Knowing through the year which costs will be allowed is what makes that estimate realistic. Our explainer on corporate tax in Cyprus covers the rate, the reform and the return in full.

How does Sumly keep expense evidence attached to the books?

It makes the document the starting point of every entry. You drop receipts and supplier bills into Sumly, or forward them to your company's private Sumly email address. The AI reads the supplier, date, amounts, line items and VAT, books the expense in double entry, and stores the file against the entry. The invoice and the ledger line can't drift apart. Your bank transactions arrive over a read-only open banking feed and match automatically against those recorded purchases, so each expense carries its invoice and its payment together.

That's the evidence standard from the section above, applied on the day the cost happens, not pieced together at year end. And because bookkeeping starts the day you order company formation, even your earliest costs land in the books with their documents.

What Sumly doesn't do is rule on deductibility. The capital allowance rate, the entertainment cap and the business share of a mixed cost are judgements made from the records. On Base, you make them with your accountant, and you file the returns Sumly prepares. On Plus, Sumly files every return except the year-end accounts. VIES is the return that lists your sales to businesses in other EU countries. On Premium, your Sumly certified bookkeeper reviews the books and handles every filing. Whoever prepares the computation works from a ledger where every deduction already has its proof attached.
