Millions of Social Security beneficiaries in the United States are still waiting for their March 2026 Social Security payments. The Social Security Administration (SSA) follows a strict payment calendar based on birth dates. Retirees born between the 11th and 20th will receive deposits on March 18, 2026. Those born between the 21st and 31st will get payments on March 25. Americans born between the 1st and 10th already received checks on March 11. Meanwhile, SSI recipients were paid earlier on February 27 because March 1 fell on a Sunday. The next SSI payment will arrive on April 1, according to SSA schedules.
