The Pension “Last 7 Years” Trap: Turkey’s SSI Cannot Force You Into Bağ-Kur — What the Court of Cassation Ruled

A client came in last month holding his SSI service record and said one sentence: “I was going to retire from SSK, but because I was a company partner in recent years they pushed me into Bağ-Kur, and now I supposedly have to work another year.” Looking at the numbers, he had long since completed 25 years and well over 5,000 SSK days; yet the SSI had found his Bağ-Kur premium days higher in the last seven years before the claim and steered him toward Bağ-Kur retirement, which demanded 9,000 days. The bitter part was that this was not fate but an administrative act that can be annulled — one most people simply swallow because they do not know otherwise.

Regulatory Note: As of 10 July 2026 this article is based on Law No. 2829, Art. 8, which determines the institution that grants the pension in a service merger, and Art. 7 governing the day count (Official Gazette 27.05.1983, No. 18059); Law No. 5510, Art. 53 (as amended by Law No. 6111, Art. 33) and Provisional Art. 2, which regulate priority in overlapping insurance; the status laws No. 506 (SSK), No. 1479 (Bağ-Kur) and No. 5434 (Emekli Sandığı); and the Court of Cassation Assembly of Civil Chambers decision Merits 2025/565, Decision 2026/259, dated 15.04.2026. The decision concerns an individual dispute and does not apply to everyone automatically; your specific situation requires professional assessment with your service record.

60-Second Summary

• What does the rule say? When periods served under more than one status (SSK/4a + Bağ-Kur/4b + Emekli Sandığı/4c) without overlap are merged, the pension is granted by the institution with more service within the last seven years of actual service counted backward from the claim (Law No. 2829, Art. 8). “Seven years” is not calendar time but the last 2,520 days on which premiums were paid.
• Why the harm? While SSK may need 5,000 days, this rule can drop you into Bağ-Kur, which demands 9,000: later retirement, harsher conditions, a lower pension.
• What did the Court say? An insured who meets the retirement condition under a single status cannot be forced into service merger; their will prevails (Assembly of Civil Chambers, Merits 2025/565, Decision 2026/259, 15.04.2026, final by unanimous vote). The disadvantageous status service can be excluded and the pension granted from the advantageous status.
• Is this a revolution? No. The ruling explicitly says “as stated in precedent decisions”; the principle is settled. Its value is that it reinforces the rule at Assembly level with a current decision.
• Who does it concern? Mainly those first insured before 1 October 2008. For anyone insured afterward, there is no last-7-years rule (Law No. 5510, Art. 53/1).

What Exactly Is the “Last 7 Years Rule”?

This is one of the most misunderstood concepts in Turkish social security, because two distinct legal situations are constantly confused: overlapping insurance and service merger. You cannot frame the issue correctly without separating them.

Overlap means being subject to two statuses in the same calendar period. If, for example, a person works as a 4/a (SSK) employee at one company while also counting as 4/b (Bağ-Kur) because they are a partner in another, that period overlaps. Which status governs an overlap is set by Law No. 5510, Art. 53: after 2011, as a rule, when 4/a and 4/b overlap, 4/a (SSK) prevails; if 4/c (Emekli Sandığı) is involved, it takes priority.

Service merger is a different matter entirely. Here the periods do not overlap; the person was SSK-insured in one part of life, Bağ-Kur-insured in another, and a civil servant in yet another. Law No. 2829, Art. 4 merges these separate, non-overlapping periods when they are “sufficient for a pension.” Which institution grants the pension is then answered by Art. 8:

“Over the total of the merged service periods, the pension is granted and paid, under its own legislation, by the institution with the greater actual service within the last seven years of actual service; and where the service periods are equal, by the institution to which the last of the equal service periods was subject.”

Note this carefully: the Court’s ruling and the subject of this article is Art. 8, not the overlap rule of Art. 53. The press often puts the two in the same basket, yet their legal bases and outcomes differ.

So why is “seven years” 2,520 days, and “the institution with more” 1,261 days? Here we must be honest: these numbers do not appear in the text of the article; they are derived from the mechanics. Art. 7 counts each month as 30 days in the service calculation; 7 years × 360 days = 2,520 days. “The institution with more” then points to more than half of those 2,520 days, i.e. 1,261 days. If it lands exactly even, 1,260 to 1,260, the article explicitly says “the institution to which the last was subject” — the most recent status. Any text claiming the law pronounces a figure of “1,261 days” is simplifying the mechanism for you; the wording of the provision is “the institution with more.”

The source of the harm is hidden right here. While an old-age pension under SSK typically needs 25 years + 5,000 days, the day count required for older Bağ-Kur insureds rises to 9,000 days. Because your Bağ-Kur premium came out a few hundred days higher in the last seven years, the SSI “promotes” you to Bağ-Kur, and a journey that would have ended at 5,000 days suddenly stretches to 9,000.

The SSI’s Automatic Act, or Prevailing Will? By the Numbers

Let us place the two fates of the same insured side by side. The person’s real data are taken from the file that became the subject of the Court of Cassation ruling: 6,730 days SSK, 450 days Emekli Sandığı, 2,092 days Bağ-Kur; he had met the condition of 25 years of insurance and 5,000 premium days under Law No. 506; claim date 28.03.2002.

Criterion	SSI’s automatic act (Bağ-Kur/4b)	Claim via prevailing will (SSK/4a)
Status granting the pension	Law No. 1479 (Bağ-Kur)	Law No. 506 (SSK)
Basis	Bağ-Kur days “more” in last 7 years	Exclusion of disadvantageous service + prevailing will
Required premium-day threshold	~9,000 days	~5,000 days (together with 25 years)
Insured’s position	Condition unmet → +1 year of waiting	Condition met → pension immediately
Pension level	Low	High
Retirement timing	Delayed	Starts on 01.04.2002
Outcome	Harm, quietly swallowed	Litigation → arrears + interest

Simulation notes. The first-instance court found that the claimant should be granted a pension as of 01.04.2002 using only Law No. 506 service; it set the pension on that date at TRY 234.39, and ruled that up to 25.05.2012 there were arrears of TRY 8,654.29 plus TRY 6,692.48 in interest. The 6,730/450/2,092 days and the amounts here are taken verbatim from the decision. The general thresholds (2,520 / 1,261 days) are derived from the mechanics of Law No. 2829, Art. 8; the person-specific days and pension amount always depend on the expert calculation, the earnings base, and the pension start date — there is no fixed “you will receive this much” figure.

The table shows one thing: the gap is not “bad luck” but money and time. Which side of that gap you end up on is usually decided by whether you made the right request at the right moment.

Who Should Sue? A Decision Matrix

Not every multi-status pension candidate is a party to this lawsuit. Answer four questions in order:

1. Do you meet the independent retirement condition under a single status? For instance, do your SSK service years alone reach 25 years + 5,000 days? If you cannot say “yes,” prevailing will does not save you, because you are already obliged to merge. The principle works precisely for someone with sufficient service on their own.
2. Did the SSI drop you into a worse status? If the last-7-years rule moved you from SSK to Bağ-Kur, and that came back to you as a later age / more days / lower pension, the harm is concrete.
3. Which status is truly advantageous? This is not as simple as “SSK is good.” In some files Emekli Sandığı comes out ahead, in others SSK. The decision is made with an advantage simulation run separately per status.
4. Which services will you ask to be excluded? This is the real technical point the Court underlined in this ruling. The Court solved the dispute less through substantive law than through procedure: what you request precisely in your statement of claim is decisive (Code of Civil Procedure Art. 24, the party-disposition principle, and Art. 119, the statement of claim). Because the claimant said “exclude my Bağ-Kur service, grant the pension over SSK,” the court could not go beyond the claim and merge other service. Frame your request wrongly and you may lose the case on technical grounds even though you are right.

Let us also state clearly whom the rule does not concern at all. The last-7-years rule applies only to those first insured before 1 October 2008 (through the reference in Law No. 5510, Provisional Art. 2, the repealed Law No. 2829 continues to apply). For anyone first insured on or after 1 October 2008 there is no last-7-years rule; under Law No. 5510, Art. 53/1 the look is not at the recent period but at the status with the most premiums across the entire working life. Moreover, the last paragraph of Art. 8 does not run the last-7-years calculation at all in cases of disability, death, mandatory retirement on age limit, appointment/election to an office whose term is set by law, and a change of institution by law — it takes the last status directly as the basis.

Gökay GÜL’s Note: The most expensive mistake I see in the field is filing the pension claim without breaking the service record down by status. The SSI system automatically selects “the institution with more”; it will not make the choice in your favour on your behalf. Before you file, always draw up a three-column table — SSK days, Bağ-Kur days, Emekli Sandığı days — and run the simulation of “under which status do I meet the condition on my own, and which gives me an earlier and higher pension.” Then apply to the SSI with a petition that explicitly states which premiums you want excluded. The wording of that petition determines the fate of the lawsuit you may bring.

From the Field: The File That Turned Back a Year of Extra Work

A long-serving foreman at a mid-sized manufacturing workshop of Central Anatolian origin appeared to be Bağ-Kur-insured because of a brief partnership in the final stretch of his career. On the SSK side he had long finished 25 years and over five thousand days; the retirement date was clear in his mind. When he applied to the SSI, the answer stunned him: because his Bağ-Kur days in the last seven years came out “higher,” he was being assessed under Bağ-Kur, and reaching the required day count there meant paying premiums for roughly another year.

His first reaction was like most people’s: “If the state says so, there’s nothing to be done.” But there was something to be done. When we separated the service record by status, it was clear that once the Bağ-Kur days were excluded from the table, his SSK service alone sufficed for retirement. With a correctly framed petition — “grant the pension over my SSK service, without merging my Bağ-Kur periods” — he applied to the SSI; the expected rejection came; then a lawsuit for annulment of the act and declaratory relief was filed at the Labour Court.

Applying the settled “prevailing will” principle, the court found the claim well-founded: the disadvantageous status is excluded, and the insured is retired from the status that suffices on its own. In the end, a year of needless waiting gave way to the correct pension running back to the original claim, plus accrued arrears and interest. The lesson lay in method more than in the amount: what determined the harm was not the SSI’s automatic act, but whether the insured objected to that act at the right time and in the right language.

Frequently Asked Questions

1. What is the “last 7 years rule” and whom does it affect? For people who paid premiums, without overlap, under more than one social security status (SSK, Bağ-Kur, Emekli Sandığı), when services are merged the pension is granted by the institution with more service in the last seven years (2,520 days) of actual service counted backward from the retirement claim (Law No. 2829, Art. 8). It mainly affects those first insured before 1 October 2008; for those first insured afterward the rule does not apply.

2. Can the SSI compulsorily retire me from Bağ-Kur? If you meet the independent retirement condition under a single status, no. Under the Court of Cassation’s settled precedent, an insured cannot be forced into service merger and their will prevails (Assembly of Civil Chambers, Merits 2025/565, Decision 2026/259). The SSI’s mechanical application of the last-7-years rule to drop you into the harsher Bağ-Kur track is an act that can be annulled insofar as it disregards your will.

3. I met my SSK condition, but my Bağ-Kur premium is higher in the last 7 years — what can I do? You can request that your disadvantageous Bağ-Kur service be excluded and the pension granted over SSK. First apply to the SSI with a petition that states this request clearly; if it is rejected, file suit at the Labour Court for annulment of the act, a declaration of the correct status, and pension arrears. Frame your request by naming exactly which services are to be excluded; the Court treated the scope of the claim as decisive in this ruling.

4. How do I use the Court of Cassation ruling in court? The ruling does not apply automatically to your file (it binds only its own parties); however, it is a strong basis as precedent. Being issued at Assembly level, by unanimous vote and as a final decision, increases its persuasive power before the first-instance court. In your statement of claim, cite the principle (“no compulsion to merge service, prevailing will”) and the case reference as grounds.

5. Can I recover retroactive arrears and interest? Is there a time limit? Yes; if the case is won, the pension is, as a rule, granted from the correct status as of the month following the original claim, and arrears plus interest accrued since that date can be claimed. However, the forfeiture period, the application requirement, and the start of interest (the processing period under Law No. 5510, Art. 42, or the point of maturity) vary by file. Refund of the excluded Bağ-Kur premiums is usually a separate debate and is generally rejected; that is why the litigation strategy must be framed correctly from the outset.

What to Do Now

1. Break your service record down by status. See your SSK, Bağ-Kur and Emekli Sandığı days in separate columns; the e-Devlet record is the starting point.
2. Verify your first insurance date. If it is before 1 October 2008, the last-7-years rule applies to you; if after, the litigation part of this article does not concern you.
3. Test the independent retirement condition. Do you meet 25 years + the required days under any single status on its own? If not, merger is unavoidable.
4. Have an advantage simulation done. Compare, with a professional calculation, which status gives the earlier and higher pension.
5. Apply to the SSI with the correct petition. State clearly which services you want excluded; if rejected, file suit at the Labour Court (venue under Code of Civil Procedure Art. 14) for annulment + declaratory relief + arrears and interest. At this stage work with a labour/social security lawyer; the accountant handles the service record and simulation, the lawyer runs the litigation.
