If I miss a year of paying social security can I collect social security when I retire?

Yes, you can still collect Social Security benefits even if you miss a year of payments. The Social Security Administration calculates your benefits based on your highest 35 years of earnings, so missing a year may affect the amount you receive, but it doesn't disqualify you from benefits. However, it's important to maintain a minimum of 40 credits, which typically equates to about 10 years of work, to qualify for retirement benefits.
