The shape of the question
Start with the official number. SSA announced a 2.8 percent Social Security COLA for 2026.
Source trail: SSA.gov
Then separate gross from net. CMS lists 2026 Medicare Part B premiums, and those premiums can change what actually lands in the bank account.

Then place the benefit on the tax return. IRS Publication 915 explains when part of a Social Security benefit can be taxable under federal rules.

Finally, use a personal estimate. SSA points people to personal benefit estimates because benefit dollars depend on earnings history and claiming age.
