The Notional Interest Deduction (NID) is one of Cyprus's most underused tax tools. It allows Cyprus companies to deduct a fictional interest payment on their equity capital, reducing taxable profit and corporate tax — at zero cost and without any actual interest being paid.
A Cyprus company with EUR 500,000 of qualifying equity and a NID rate of 5.3% can deduct EUR 26,500 from its taxable profit. At 15% corporate tax, that saves EUR 3,975 in tax annually — every year, without spending a cent.
What Is the NID?
The Notional Interest Deduction was introduced in Cyprus in 2015, inspired by Belgium's earlier "Notional Interest Deduction" concept. The idea: equity capital deserves the same tax treatment as debt capital.
When a company borrows money, the interest it pays is tax-deductible. When a company uses equity (shareholder investment), there is no equivalent deduction. The NID corrects this asymmetry by allowing a fictional interest deduction on equity.
The formula:
NID Deduction = New Qualifying Equity x NID Reference Rate
Where NID Reference Rate = Cyprus 10-year government bond yield + 3%
What Counts as Qualifying Equity
| Qualifies | Does Not Qualify |
|---|---|
| Paid-up share capital injected after 1 January 2015 | Share capital existing before January 2015 |
| Share premium received after January 2015 | Retained profits accumulated before January 2015 |
| Retained profits reinvested as equity after 2015 | Loans from shareholders |
| Equity from reorganizations after January 2015 | Goodwill or intangible assets |
Key rule: The equity must represent genuine new capital — not just accounting entries. The company must have actual cash or assets to match the equity on the balance sheet.
The NID Rate: Annual Reference
The NID rate is calculated as: Yield on 10-year Cyprus government bonds + 3%
The reference rate changes each year based on bond yields. In recent years:
| Year | Approximate NID Rate |
|---|---|
| 2022 | ~3.5% |
| 2023 | ~5.0% |
| 2024 | ~5.3% |
| 2025/2026 | ~5-6% (verify with accountant) |
Your accountant confirms the exact rate applicable to the current tax year.
Worked Examples
Example 1: Startup with EUR 100,000 Equity
| Item | Amount |
|---|---|
| Qualifying equity | EUR 100,000 |
| NID rate | 5.3% |
| NID deduction | EUR 5,300 |
| Taxable profit (before NID) | EUR 80,000 |
| Taxable profit (after NID) | EUR 74,700 |
| Corporation tax saving (15%) | EUR 795 |
Example 2: Established Company, EUR 500,000 Equity
| Item | Amount |
|---|---|
| Qualifying equity (cumulative injections + retained profits since 2015) | EUR 500,000 |
| NID rate | 5.3% |
| NID deduction | EUR 26,500 |
| Taxable profit (before NID) | EUR 200,000 |
| Taxable profit (after NID) | EUR 173,500 |
| Corporation tax saving (15%) | EUR 3,975 |
Example 3: Funded SaaS with EUR 1,000,000 Equity
| Item | Amount |
|---|---|
| Qualifying equity | EUR 1,000,000 |
| NID rate | 5.3% |
| NID deduction | EUR 53,000 |
| Taxable profit (before NID) | EUR 300,000 |
| 80% cap (EUR 300,000 x 80%) | EUR 240,000 maximum NID |
| Applied NID deduction | EUR 53,000 (within cap) |
| Taxable profit after NID | EUR 247,000 |
| Corporation tax saving (15%) | EUR 7,950 |
The 80% Cap
The NID deduction cannot exceed 80% of the company's taxable income for the year. This prevents the creation of a NID-driven tax loss.
Example of cap triggering: Company has EUR 5,000,000 in equity, NID deduction = EUR 265,000. But taxable profit is only EUR 200,000. Maximum NID = 80% x EUR 200,000 = EUR 160,000. Only EUR 160,000 can be deducted in this year (the remaining EUR 105,000 cannot be carried forward — it is simply lost for that year).
NID + IP Box: Can You Use Both?
Yes, both deductions can be applied in the same year. However, since both cap at 80% of taxable income, the order of application matters:
- Apply IP Box deduction first (if applicable) — reduces taxable income
- Apply NID to the remaining taxable income
- Both deductions combined cannot exceed the taxable income (you cannot create a loss solely from these deductions)
Your auditor will optimize the calculation in the TD4.
Who Benefits Most from NID
High benefit:
- Companies that have received significant equity investment (angel, VC, founder injection)
- Companies with years of reinvested retained earnings (large equity base)
- Holding companies with substantial equity from asset contributions
Low benefit:
- Companies with minimal equity (e.g., EUR 1,000 share capital, all profits distributed)
- Companies with high profits relative to equity base (where 80% cap rarely binds)
Practical action: If you plan to inject capital into your Cyprus company (as equity, not as a loan), the NID makes equity more tax-efficient than it would otherwise be. Consider converting existing shareholder loans into equity to maximize qualifying NID base.
How to Apply the NID
You do not apply the NID yourself. Your accountant:
- Reviews the equity history of the company
- Identifies all qualifying equity injections since January 2015
- Calculates the NID deduction for the current year
- Applies it in the TD4 corporate tax return
- Ensures the 80% cap is not exceeded
Provide your accountant with a clear history of all capital injections, dates, and amounts. This information is typically in the company's statutory books and balance sheet.
