⚠️ The Problem

Why Section 39 Pensions
Collapse Unfairly

A pathway that should protect your retirement — designed to reduce it instead.

STEP 1
👷
Section 33 — 20–30 years

Contributed as an employee at 15,000–23,000 THB/month throughout your working life.

STEP 2
🔄
Switch to Section 39

Left employment. Switched to Section 39 to maintain SSO coverage — fixed base of only 4,800 THB/month.

STEP 3
📉
Pension Recalculated

SSO averages all years together — dragging the lifetime average far below your actual Section 33 earnings.

RESULT
😱
Unfair Pension

Instead of 5,000–7,000 THB/month, you receive only 1,500–2,500 THB. Decades of contributions — for almost nothing.

Real Example — 25 years Sec.33 + 5 years Sec.39

Pension you should receive
~5,800 THB/mo
Based on Section 33 history alone
Pension you actually receive
~2,200 THB/mo
After Section 39 base drags average down

🧮 Understand the Formulas

What Is the CARE Formula?

Career Average Revalued Earnings — the formula the SSO is pushing for, but not yet in effect.

📌 Currently, the SSO still uses the old formula FAV (Final Average Value) — calculated from the average of the last 60 months before receiving pension. This is the formula Supreme Court ruling 3307/2567 found to be unfair for those who switched to Section 39.
📌 Current Formula (FAV)
Pension = 1.5% × Years ×
Avg last 60 months
12 months
⚠️ If last 60 months = Sec.39 at 4,800 THB — pension halved
⚠️ CARE Formula (SSO proposal)
Pension = 1.5% × Years ×
Avg wage lifetime
12 months
❌ Still includes 4,800 THB base — Sec.33 pension drops 10–20%
VS
✅ B60M Formula (fair solution)
Pension = 1.5% × Years ×
Avg best 60 months
12 months
✅ 4,800 THB never reduces your pension — fixes both Sec.33 and Sec.39
🧮 Compare: CARE vs B60M

❓ Frequently Asked

FAQ: Section 39 Class Action

Section 39 covers voluntary insured persons — former Section 33 (employee) contributors who left employment but want to maintain SSO coverage. Their contribution base is fixed at 4,800 THB/month, regardless of their previous actual salary.
The SSO averages the 4,800 THB Section 39 base with all previous Section 33 years, drastically lowering the lifetime average. For example: 25 years at 20,000 THB (Sec. 33) + 5 years at 4,800 THB (Sec. 39) gives an average far below the actual Section 33 contribution history — and thus a much lower pension.
Ruling 3307/2567 established that continuing contributions as Section 39 is meant to add rights — not reduce rights already accrued under Section 33. The SSO cannot use the Section 39 period to lower a pension already earned. This is the key legal foundation for the class action.
A class action groups many people with the same legal issue to sue together in a single case. Benefits:
  • Reduces individual legal costs
  • Increases legal weight and chance of winning
  • Creates systemic change for all affected workers
If the class wins, all registered members benefit.
Those likely eligible:
  • Contributed for many years under Section 33
  • Then switched to Section 39
  • Received or expect a significantly reduced pension
We recommend calculating your pension first to confirm the impact.
Currently — completely free. Filling the form, joining the LINE group, and receiving all information costs nothing. Any court fees for the actual litigation will be decided collectively as the case develops, and you will be informed clearly before any commitment.
CARE (Career Average Revalued Earnings) is a proposed new SSO pension calculation — not yet in effect. The current system uses FAV (Final Average Value), averaging the last 60 months. This is precisely what ruling 3307/2567 found to be unfair when Section 39 periods drag down the average. The class action targets this existing unfairness.
