What is the Social Security Base Amount? How is it Calculated?

Therefore, in this article, we comprehensively address the following questions: What is the social security base amount, what does it cover, how is it calculated, and what are the lower and upper limits of social security base amount for 2026?

What Is a Premium?

A premium is the social security contribution paid to the Social Security Institution (SSI) by both the employee and the employer. It serves as the basis for accessing entitlements such as retirement, illness, and work accident benefits. The type of income on which this premium is based—namely, which payments are subject to premiums—is determined by the social security base amount.

What Is the Social Security Base Amount?

Since an employee's retirement premiums, sickness and maternity benefits, and social security entitlements such as work accident and occupational disease benefits are calculated based on this base amount, the accurate and complete reporting of the social security base amount is a responsibility with both financial and legal consequences.

What Are the Types of Social Security Base Amounts?

According to SSI regulations, not every type of payment is included in the social security base amount. Some payments are mandatorily added to the base, some are partially considered, and others are entirely excluded. Making this distinction accurately is essential for both the correctness of declarations and the transparency of payroll records.

1. Earnings Fully Subject to Premiums

The following items are directly included in the social security base amount:

• Gross wage (salary, wage)
• Overtime payments
• Bonuses and incentives (performance-based, sales-based, etc.)
• Work performed on weekly rest days and public holidays
• Meal allowance paid in cash (the portion exceeding the exemption limit)
2. Earnings Partially Included in the Social Security Base Amount

Some payments are subject to premiums only to the extent that they exceed certain thresholds. As of 2026, the limits for these payments are as follows:

Type of Payment	Exemption (2026)	Explanation
Meal allowance	TRY 300.00 (daily)	For cash payments; the excess is included in the base amount
Child allowance	TRY 660.60 (monthly)	Included if it exceeds the specified limit
Family allowance	TRY 3,303.00 (monthly)	The portion exceeding the benchmark is included in the base amount

3. Earnings Not Subject to Premiums

The following are not included in the premium base under any circumstances:

4. Benefits in Kind
5. Severance payment
6. Per diem allowance
7. Death, childbirth, and marriage allowance
8. End-of-employment or lump-sum payments considered as severance payment
9. Cash benefit

How Are Meal, Family, and Child Allowances Evaluated in the Social Security Base Amount?

One of the most confusing issues in practice is the impact of social assistance-type payments on the SSI base. For example, an employer who makes a cash payment instead of providing a meal card to an employee can exempt only up to TRY 300.00 per day of this payment in 2026. Any amount exceeding this limit must be added to the social security base amount.

Similarly, family allowances paid to married employees and child allowances paid to those with children are assessed within the limits set by the SSI. If these limits are exceeded, the relevant amounts are directly reflected in the SSI declaration base.

Note: In order for the exemption to be applicable, the payments must be shown as separate items on the payroll and must be documented.

How Is the Social Security Base Amount Calculated?

The calculation of the social security base amount is critically important for accurately determining the monthly base to be reported to the SSI.

Steps:

1. The gross wage is determined.
2. The following are added to this amount:
• Overtime,
• Bonuses and incentives,
• Meal, child, and family allowances (those subject to premiums)
3. The resulting total is the social security base amount to be reported to the SSI.

Example of Social Security Base Amount Calculation (2026)

Example: Let's assume that an employee received the following payments in April 2025.

• Gross salary: TRY 70,000.00
• Overtime payment: TRY 4,000.00
• Bonus (performance incentive): TRY 5,000.00
• Meal allowance (in cash): TRY 400/day × 22 days = TRY 8,800.00
• Child allowance: TRY 750,00
• Family allowance: TRY 4,000.00

Step 1: Identifying Payments to Be Included in the Social Security Base Amount

Note:

• Meal allowance exemption limit: TRY 300.00/day × 22 days = TRY 6,600.00
• Amount included in the base: TRY 8,800.00 – 6,600.00 = TRY 2,200.00
• Child allowance exemption limit: TRY 660.60
• Amount included in the base: TRY 750.00 – 660.60 = TRY 89.40
• Family allowance exemption limit: TRY 3,303.00
• Amount included in the base: TRY 4,000.00 – 3,303.00 = TRY 697.00

Step 2: Calculation of the Total Social Security Base Amount

Step 3: Checking the SSI Social Security Base Amount Limits (2026)

Evaluation:

The total social security base amount of TRY 81,959.40 falls within the lower and upper limits set for the year 2026. Therefore, this full amount must be reported to the SSI.

Lower and Upper Limits of the Social Security Base Amount (2026)

As in every year, the SSI has determined the daily lower and upper limits for the social security base amount for 2026. These limits represent the minimum and maximum levels for reporting, and the reported earnings cannot fall outside this range.

• Daily minimum earnings limit: TRY 1,101000
• Daily maximum earnings limit: TRY 9,909.00
• Monthly minimum earnings limit: TRY 33,030.00
• Monthly maximum earnings limit: TRY 297,270.00

It is not permissible to report a base amount to the SSI below or above these limits. In particular, for high-earning employees, the entire wage is not reported to the SSI; premiums are calculated only up to the upper limit.

Important Notes:

• Meal Allowance: For 2026, cash meal allowances up to TRY 300.00 per day are not included in the social security base amount. Any amount exceeding this is included in the base. If a meal card, voucher, or coupon can be used solely for the payment of meal expenses, the entire amount of the payment is considered within the scope of the exemption. However, if these instruments can also be used for non-meal expenditures, the amount exceeding TRY 300.00 per day shall be included in earnings subject to social security contributions.
• Child and Family Allowances: For 2026, child allowances up to TRY 660.60 per month and family allowances up to TRY 3,303.00 per month are not included in the social security base amount. Any amounts exceeding these limits are included.
• Social Security Base Amount Limits: The amount to be reported to the SSI must fall between the specified lower and upper limits. Any amounts outside these boundaries are not considered.

This example has been prepared to assist employers and HR professionals in making accurate SSI declarations within payroll processes. Exercising care in calculating the social security base amount is of great importance for fulfilling the employer's legal obligations and safeguarding employees' social security rights.

What Is the Difference Between the Social Security Base Amount and Gross Salary?

Conclusion: The Social Security Base Amount Is Not Just for SSI Reporting, but a Strategic Payroll Component

The social security base amount is not merely a legal reporting requirement; it is also a strategic component that directly affects the company's payroll structure, employees' social entitlements, and long-term financial costs. Incorrect or incomplete declarations may result in penalties during SSI audits and can lead to reduced retirement benefits for employees.
