About Seniors Audit
Built by someone who wanted better answers for the people who deserve them.
Seniors Audit was founded by T. Emmanuel with one purpose: to give American seniors the plain, honest information that government agencies provide in documents almost nobody can understand.
The people who use this site spent their lives working, raising families, paying taxes, and contributing to this country. When they reach retirement, they deserve answers — not bureaucratic language, not vague disclaimers, and not advice designed to sell them something.
Every guide, calculator, and notice explainer on this site is verified against the official publications of the Social Security Administration, the Internal Revenue Service, and the Centers for Medicare and Medicaid Services before it is published.
Seniors Audit is independent. It is not affiliated with, endorsed by, or connected to any government agency.

How we make sure every answer is accurate.
- Official formulas only. Every calculator uses the exact formulas published by SSA, IRS, or CMS — not approximations.
- Review dates shown on every page. Every page shows the date it was last reviewed and updated. Government rules change, and so do we.
- Direct links to primary sources. Every rule or figure links directly to its official government source — SSA.gov, IRS.gov, or Medicare.gov.
- Education, not advice. Every page includes a clear disclaimer that Seniors Audit provides education only — not legal, tax, or financial advice.

Real situations, real resolutions
This could be your situation too.
These are representative examples based on the real types of situations Seniors Audit was built to help with.
IRS Notices
Dorothy, 69 Retired nurse
She received a CP2000 notice proposing $4,200 in additional taxes. She almost paid it immediately. Instead, she used the Seniors Audit IRS Notice guide, learned the notice was based on a pension already reported on her return, and responded in writing within the 60-day window. The IRS closed the case. She owed nothing.
Representative example based on common CP2000 scenarios. Results vary. Always verify directly with the IRS.
See the CP2000 guide →Medicare
James, 71 Retired county worker
James enrolled in Medicare Part B two years late without realizing his wife's employer plan didn't protect him. The Part B Penalty Calculator showed he was paying a permanent 20% surcharge — $37 more every month for life. He also learned about his state's Medicare Savings Program, which may cover his entire premium.
Representative example. Penalty amounts and program eligibility depend on your specific situation and state.

Carol, 66 Widowed two years ago
Carol was collecting her own Social Security benefit of $880 per month. A friend mentioned survivor benefits. Using our guide, Carol learned she may be entitled to her late husband's benefit of $1,740 per month — more than double her own. She called the SSA and filed for the adjustment.
Representative example. Benefit amounts depend on individual earnings records. Contact SSA to confirm your entitlement.
