| Pension replacement | ~40% | ~48% | ~60% |

## Totalization Agreements

When moving between countries, totalization agreements prevent double social security taxation and preserve your benefits. The US has agreements with over 30 countries.

Without an agreement, you could pay into two systems and not qualify for benefits from either.

## Strategies to Manage Social Security Costs

1. **Understand caps**: In the US, Social Security tax stops at $176,100. Income above this is only subject to Medicare (1.45%).
2. **Totalization certificates**: Get a Certificate of Coverage (CoC) before working abroad.
3. **Self-employment**: In some countries, self-employed rates differ from employee rates.
4. **Company structure**: In some jurisdictions, contractor vs employee status affects contributions.

## Key Takeaways

1. Social security adds 8-56% to the cost of employment.
2. High-contribution countries provide more benefits in return.
3. Singapore's CPF is different — contributions go into your personal account.
4. Always factor social security into cross-country salary comparisons.
5. Totalization agreements are essential when working across borders.
