What Counts as Taxable Income?

Cardio Renal Foundation is a 501(c)(3) tax-exempt charity organization. Your donation advances our mission to provide a solution beyond dialysis.

Ask a room of retirees what counts as taxable income and you will get confident answers that contradict each other — because the honest answer is two lists, not one, and most people have only ever seen pieces of each. This page is both lists, complete and in plain words: the money the IRS counts, and the money it does not. It matters more than it used to. What counts decides your tax bill directly — and, one step removed, it also decides how much of your Social Security gets taxed and what your Medicare premiums cost, because both of those are measured off the same pile.

What Counts

The tax code starts from a sweeping rule — income from whatever source, unless the law specifically excuses it — and these are the items that land in a typical retiree's pile:

• Wages — from a full-time job or the part-time work many people keep into their seventies.
• Pensions and annuities — the taxable part of each payment, which for most pensions is most of it.
• Withdrawals from a traditional IRA or 401(k) — every dollar counts, including the required minimum distribution the IRS forces out each year from age 73. The money went in untaxed and grew untaxed; the exit is where it is counted.
• Interest — bank accounts, CDs, bonds. (One exception lives on the other list, below.)
• Dividends — from stocks and funds; some are taxed at gentler rates, but they are counted.
• Capital gains — the profit when you sell investments or property for more than you paid.
• Rental income — what remains after the expenses of being a landlord.
• Business and self-employment income — the shop, the consulting, the craft fair, if they turn a profit.
• Unemployment compensation — yes, it counts.
• Part of your Social Security — up to 85% of your benefits, decided by a measuring number built from this very list. That calculation has its own page, because it deserves one: is my Social Security taxable?

What Does Not Count

The second list is shorter, and it holds most of the surprises — including the item this Foundation most wants you to notice:

• Gifts you receive. Money or property someone gives you is not income to you, whatever the amount. Any gift-tax questions belong to the giver, never the receiver.
• Inheritances. Money or property left to you is not federal income to you either. (A small number of states levy their own inheritance tax — a separate, state matter.)
• Life insurance payouts. A death benefit paid to a beneficiary is not income.
• Qualified withdrawals from a Roth IRA. The tax on Roth money was paid on the way in; qualified withdrawals come out untaxed and uncounted.
• Municipal bond interest. Not taxed itself — with one string attached: it still counts inside the measuring number that decides how much of your Social Security is taxed. Untaxed is not always uncounted.
• Money you borrow. A loan is not income, because it has to be repaid.
• An RMD given straight to charity. This is the one with a door in it. A required minimum distribution normally counts in full — it sits on the first list above. But if the distribution travels directly from your IRA custodian to a qualified charity — a qualified charitable distribution, or QCD — it never becomes income at all. It isn't counted, then excused; it simply never enters the pile, while still satisfying your required distribution in full. No other common item on either list behaves that way.

Where the Tax Brackets Fit

One confusion to clear, because the two phrases are cousins and get used as twins. Taxable income is the number this page has been sorting out — the pile, after your deductions come off the top. The standard deduction (or your itemized deductions, if they are larger) is subtracted first; what remains is your taxable income. Tax brackets are what happens next: the rate schedule applied to that number in slices — the first slice taxed gently, the next a little harder, and only the top slice at your highest rate. Nobody pays their top rate on all of their income; they pay it on the last slice only. We keep the actual 2026 schedule — every bracket, both filing pictures — on its own page: what are the 2026 tax brackets?

Why the distinction matters on a page about what counts: the items on the first list stack. Your pension fills the lower slices; your interest and dividends stack on top; and the forced IRA withdrawal — the one you may not need and cannot refuse — lands last, in the highest slice you reach, taxed at your top rate. That is why the QCD item on the second list carries weight out of proportion to its length. It is the one legal move that keeps a whole item off the stack entirely — not deducted from it, not taxed gently inside it. Absent from it.

Why This Foundation

If the QCD door is the one you choose, the remaining question is which charity stands on the other side of it — and here is this Foundation's answer, in one paragraph. The Cardio Renal Foundation exists for the people living with kidney and heart disease, and its conviction is plain: dialysis should not be a life sentence. The gifts that arrive here keep a library of plain-words articles — health pages and money pages like this one — free for the seniors who rely on them, along with a shelf of free everyday tools: grocery lists, calendars, recipe boxes. A QCD has one more virtue worth naming: because no tax is taken out of it on its way, the full amount you send is the amount that arrives — every dollar of it goes straight to work.

Stated Plainly

Stated plainly, because a money page owes you the same honesty as any other kind: this page explains how the rules work in general. It is not advice about your return. The lists above cover the common retiree picture; unusual income — a business sale, a lawsuit settlement, foreign income — has its own corners, and a qualified tax advisor who knows your situation is the right referee for your own numbers. And what can be checked, check: our legal name is Cardio Renal Foundation Inc, our EIN is 33-4359765, and we are a qualified 501(c)(3) tax-exempt organization — verifiable in the IRS records by anyone, in about three minutes, and we would rather you checked than took our word.

The rules described are the federal rules in effect for 2026. Questions reach a person here, at donations@cardiorenalfoundation.org or (646) 770-3946.
