The interest limitation rule of § 4h EStG restricts the tax deduction of interest expense and must be considered in every debt-financed cross-border structure. It is intended to prevent profits being shifted abroad through excessive intra-group financing. Anyone who knows the safe harbour and the exceptions can design financing cleanly.
The basic rule: 30% of EBITDA
Net interest expense – the balance of interest expense and interest income – is deductible only up to 30% of tax EBITDA. The excess is not deductible in the current year. The rule implements the European interest limitation of the ATAD and applies in Germany as in its Cyprus equivalent.
The safe harbour
Below a safe-harbour threshold the interest deduction remains unrestricted. If net interest expense is below the threshold of three million euros, the interest limitation does not bite. For many mid-sized structures this safe harbour already resolves the issue entirely.
The exceptions: group and equity escape
Two exceptions can lift the interest limitation. The group clause applies where the business does not belong, or belongs only partly, to a group. The equity escape allows the full deduction where the business's equity ratio does not, or only marginally, fall below that of the group. Anyone group-affiliated and debt-financed should check these escapes.
Interest and EBITDA carry-forward
Non-deductible interest is not lost: the interest carry-forward carries it into future years without time limit. In addition, unused deduction potential can be used over several years via the EBITDA carry-forward. The interest limitation thus often merely defers the deduction rather than denying it definitively.
Relevance for Cyprus structures
When financing a Cyprus company or German activities from within the group, the interest limitation must be observed on both sides. Together with the notional interest deduction (NID) in Cyprus and the transfer-pricing rules, a coherent picture emerges that should be planned from the start.

A worked example
A business has net interest expense of EUR 5,000,000 and tax EBITDA of EUR 12,000,000. Deductible initially are 30% of EBITDA, i.e. EUR 3,600,000. The remaining EUR 1,400,000 is not deductible in the current year – but it is not lost; it is carried into future years as an interest carry-forward. If net interest expense were below the safe harbour of three million euros, full deduction without reduction would be possible.
The escapes in detail
Two exceptions can lift the interest limitation. The group clause applies where the business does not belong, or belongs only partly, to a group – the classic case of the stand-alone enterprise. The equity escape allows the full deduction where the business's equity ratio does not, or only marginally, fall below that of the group. Anyone group-affiliated and debt-financed should systematically check both escapes before assuming a reduction.
Carry-forwards as a valve
The interest limitation often does not deny the deduction definitively but defers it. Non-deductible interest moves into the future without time limit via the interest carry-forward; unused deduction potential can be used over several years via the EBITDA carry-forward. In years with higher EBITDA, the carried-forward interest can then be deducted. The carry-forwards are therefore an important valve in financing planning.
Common Questions about The Interest Limitation Rule (§ 4h EStG) in Detail
How does the interest limitation work? Net interest expense is deductible only up to 30% of tax EBITDA; the excess is not deductible in the current year.
Is there a safe harbour? Yes. If net interest expense is below three million euros, the interest limitation does not bite.
What exceptions exist? The group clause and the equity escape can lift the interest limitation where certain conditions are met.
Is non-deductible interest lost? No. The interest carry-forward carries it forward without time limit; in addition there is an EBITDA carry-forward.
The Interest Limitation Rule (§4h EStG and ATAD): The Deductibility Capped, Read Before the Financing
The interest limitation rule caps the deductibility of net interest—the German §4h EStG and the ATAD interest limitation—read before the financing, not discovered in the assessment — the system briefing first: The rule caps interest deductibility (the interest limitation of the cap sort — the net interest expense of the capped kinds: the rule as the deductibility cap; the limitation as the financing constraint, per the corporate and ATAD chapters' law), the cap is a percentage of EBITDA (the 30% EBITDA cap of the threshold sort — the net interest limited of the capped kinds: the cap of the EBITDA sort; the rule of the cap kind), the rule is read before the financing (the pre-financing reading of the timed sort — the before-not-after of the read kinds: the reading of the before sort; the rule of the timed kind), and the honesty formula opens: The interest limitation caps net interest deductibility at a share of EBITDA—the German §4h and the ATAD rule—read before structuring the financing — the cap understood, the EBITDA measured, the financing structured: the rule as a read-before constraint; whoever structures financing without reading the interest limitation structures a deduction the rule may cap, and unread interest limitation is a capped deduction discovered in the assessment. The cap note of the standing echo: The rule is read before (the interest limitation of the before sort — the assessment-discovered of the late kind: the interest limitation read before the financing, per the ATAD chapter).
The cross-reference note: The corporate, ATAD and exit chapters carry the neighbours — this chapter carries the interest limitation; the library reads its interest limitation before the financing.
The Rule in Detail: Cap, EBITDA, Exceptions
The rule briefing of the interest world: The interest limitation caps net interest (the net interest expense of the capped sort — the interest deduction limited of the capped kinds, per the corporate chapter: the net interest of the capped sort; the rule of the interest kind), the EBITDA cap governs (the 30% of EBITDA of the threshold sort — the tax EBITDA of the measured kinds: the EBITDA cap of the governing sort; the rule of the EBITDA kind), the German §4h reads (the German §4h EStG of the German sort — the Zinsschranke of the German kinds, per the exit chapter: the German §4h of the read sort; the rule of the German kind), the ATAD interest limitation reads (the ATAD interest limitation of the EU sort — the EU-implemented rule of the ATAD kinds, per the ATAD chapter: the ATAD limitation of the read sort; the rule of the ATAD kind), the exemptions read (the de minimis threshold of the exemption sort — the standalone and group exceptions of the exempt kinds: the exemptions of the read sort; the rule of the exemption kind), the carry-forward reads (the disallowed interest carry-forward of the carried sort — the future deduction of the carried kinds: the carry-forward of the read sort; the rule of the carry-forward kind), the German-questions-external reads (the German §4h questions of the referred sort — the external German advisors of the referred kinds: the German questions of the external sort; the rule of the referral kind), the professional determination reads (the interest limitation of the determined sort — the CMC and George Zourides of the mandate kinds: the determination of the professional sort; the rule of the advised kind), and the rule formula closes: measure the EBITDA, cap the interest, read the exemptions, structure before. The limitation formula: Net interest capped at 30% EBITDA plus exemptions plus carry-forward equals the interest limitation — the cap sentence of the interest limitation rule.
The referral note of the standing sort: The German rule is external (the German §4h questions of the referred sort — the CMC Cyprus scope of the implementing kind: the German §4h referred to external advisors, the Cyprus ATAD work with CMC).
Practice Lines: Reading the Interest Limitation Right
The practice briefing of the financing world: The EBITDA is measured (the tax EBITDA of the threshold sort — the cap base of the measured kind), the interest is capped (the net interest of the capped sort — the 30% cap of the applied kind), the exemptions are read (the de minimis of the exemption sort — the standalone and group of the read kind), the carry-forward is considered (the disallowed interest of the carried sort — the future deduction of the considered kind), the German is referred out (the German §4h questions of the referred sort — the external advisors of the referred kind), the structuring is before (the pre-financing structuring of the timed sort — the before-not-after of the structured kind), and the practice formula closes: measure the EBITDA, cap the interest, read the exemptions, structure before. The chapter's memory line: The interest limitation caps net interest deductibility at a share of EBITDA—the German §4h and the ATAD rule—read before structuring the financing; those who read it before structure for the cap, while the unstructured meet a capped deduction in the assessment.
The closing classification: The interest limitation rule (§4h EStG and ATAD) caps net interest deductibility at a share of EBITDA—with de minimis, standalone and group exceptions, and a carry-forward for disallowed interest—read before the financing. German §4h questions go to external German advisors; the Cyprus ATAD work is with the CMC team and George Zourides — the interest limitation is read before the financing, not discovered in the assessment.
Case Study: The Cap Read Before the Financing
The read-before story: a group read the interest limitation before structuring an intra-group financing rather than discovering the capped deduction in the assessment — the chronicle: The EBITDA was measured (the tax EBITDA of the threshold sort — "we were structuring an intra-group financing with significant interest and I assumed the interest would be deductible; our advisor flagged the interest limitation—net interest deductibility is capped at a share of EBITDA, so I needed to read the cap before structuring, not discover it in the assessment", per the corporate chapter), the interest was capped (the net interest of the capped sort — "the cap was around 30% of tax EBITDA—net interest above that wouldn't be currently deductible; measuring our EBITDA against the planned interest showed whether we'd hit the cap"), the exemptions were read (the de minimis of the exemption sort — "there were exemptions—a de minimis threshold, standalone and group exceptions; I read whether any applied to us"), the carry-forward was considered (the disallowed interest of the carried sort — "disallowed interest could carry forward—a future deduction rather than a permanent loss; understanding this shaped the picture"), the German was referred out (the German §4h questions of the referred sort — "the German §4h Zinsschranke was the German-side version—those questions went to German advisors, while the Cyprus ATAD rule was with CMC", per the exit chapter), the structuring was before (the pre-financing structuring of the timed sort — "and I structured the financing having read the cap—before, when I could adjust, not after in the assessment"), and the balance closed read: measured, capped, read — the cap read before the financing. The group's verdict: "I read the interest limitation before structuring the financing—the cap, the EBITDA, the exemptions—rather than discovering it in the assessment; the ones who structure without reading it meet a capped deduction later, and unread interest limitation is a capped deduction discovered in the assessment."
The lesson of the read-before story: The cap is read before the financing — the EBITDA measured, the interest capped and the exemptions read; and reading it before versus discovering it in the assessment is the whole discipline.
Quick FAQ on the Interest Limitation Rule
What does the rule do? Caps interest deductibility — net interest expense is deductible only up to a share of EBITDA (around 30%). What's the German version? The §4h EStG Zinsschranke — the German interest limitation; those questions go to German advisors. What's the ATAD version? The ATAD interest limitation — the EU-implemented rule; the Cyprus side is with CMC. Are there exceptions? Yes — a de minimis threshold, standalone and group exceptions. What happens to disallowed interest? Carry-forward — disallowed interest can carry forward to future deduction, not a permanent loss.
Three Takeaways on the Interest Limitation Rule
First: It caps net interest at a share of EBITDA — around 30%. Second: Read it before structuring the financing — a before-not-after matter. Third: German §4h goes to German advisors — the Cyprus ATAD side with CMC. Three lines for the interest file.
Glossary of the Interest Limitation Chapter
Interest limitation — the net-interest deductibility cap. EBITDA cap — the ~30%-of-EBITDA threshold. §4h EStG — the German Zinsschranke. ATAD interest limitation — the EU-implemented rule. Interest carry-forward — the disallowed-interest future deduction. Five terms for the interest file.
Self-Check: Five Questions on Your Interest Limitation
The cap review: Is the EBITDA measured? Is the net interest capped at the threshold? Are the exemptions read? Is the carry-forward considered? And is the German §4h referred out, the structuring done before? Five yeses: the cap is read before the financing. Every no risks a capped deduction in the assessment.
Common Misconceptions About the Interest Limitation Rule
Three corrections: "Interest is fully deductible" — net interest is capped at a share of EBITDA. "It can be handled after" — read it before structuring the financing; a before-not-after matter. "Disallowed interest is lost" — it can carry forward to future deduction. Three lines for the clear interest view.
The One Sentence on the Interest Limitation Rule
For the index card: The interest limitation rule (§4h EStG and ATAD) caps net interest deductibility at a share of EBITDA—with exemptions and a carry-forward—read before the financing. One sentence for the interest file.
Further Reading in the Interest Cluster
The interest limitation chapter branches into the corporate library: the corporate chapters for the deductibility, the ATAD chapter for the EU rule, the exit chapter for the German §4h, the substance chapters for the financing. The cluster message: The interest limitation chapter is the deductibility desk of the corporate library — the cap read before; the library reads its interest limitation before the financing.
Afterword: Unread Interest Limitation Is a Capped Deduction Discovered in the Assessment
The closing thought: The group's principle — unread interest limitation is a capped deduction discovered in the assessment — names a financing trap that assuming full deductibility sets, and the trap is real because interest is ordinarily deductible and the cap is an exception one has to know. Interest expense is ordinarily deductible—a normal business cost that reduces taxable profit—and this ordinary deductibility can lead to assuming that interest on a financing will simply be deductible, structuring the financing on that assumption without reading the interest limitation that caps the deduction. But the interest limitation rule (the German §4h EStG Zinsschranke, and the ATAD interest limitation) caps net interest deductibility at a share of EBITDA (around 30%): net interest above the cap isn't currently deductible, so a financing with significant interest relative to EBITDA can find part of its interest deduction disallowed—a capped deduction that the assumption of full deductibility doesn't anticipate, discovered in the assessment when the cap bites rather than read in the structuring when it could be planned for. The read-before discipline reads the cap when structuring the financing: the EBITDA measured, the planned interest checked against the cap, the exemptions read (the de minimis, standalone and group exceptions), the carry-forward understood—the financing structured with the cap in view, so the interest limitation shapes the structure rather than surprising the assessment. And the before-not-after timing matters because the structuring is where the cap can be planned for: read before the financing, the cap can influence how the financing is structured (the debt level, the group arrangements, whether an exception applies); discovered after, in the assessment, the financing is already in place and the capped deduction is a fact to absorb rather than a constraint to plan around—so reading the cap before preserves the ability to structure for it. The division of labour applies here too: the German §4h is a German rule, so those questions go to German advisors, while the Cyprus ATAD interest limitation is with the CMC team—each rule in its jurisdiction's lane. This is the library's before-not-after and read-the-constraint principles applied to interest deductibility: the same discipline that reads the exit taxation before the move and assesses DAC6 before the arrangement, here reading the interest limitation before the financing. So read the interest limitation before structuring a financing—the cap, the EBITDA, the exemptions—rather than discovering the capped deduction in the assessment. Interest is ordinarily deductible, which invites assuming full deductibility—but the interest limitation caps net interest at a share of EBITDA, and unread, it's a capped deduction discovered in the assessment, one that the group assuming full deductibility meets after the financing is structured, while the one who reads the cap before structures for it, the interest limitation shaping the financing rather than surprising the assessment it would otherwise, unread, spring upon.
