The total after-tax money you put into the annuity.
Multiply your annual payment by the number of years (e.g. $12,000 x 12 years).

What This Calculator Does and Why It Matters
When you receive annuity payments, not every dollar is necessarily taxable. The taxable portion depends on the type of annuity you have and how it was funded. This free calculator helps you figure out exactly how much of your annuity income is taxable and how much is tax-free, along with an estimate of what you might owe each year.
Without knowing your taxable amount, you could end up underpaying taxes and facing a penalty, or overpaying and missing money that rightfully belongs to you. This tool takes the guesswork out of it by applying the IRS exclusion ratio method for non-qualified annuities and straightforward full taxation for qualified annuities.
The IRS Publication 575 covers pension and annuity income tax rules in full detail, and this calculator is built around those official guidelines.
How to Use This Calculator
Step-by-Step Instructions
- Select your annuity type — non-qualified (funded with after-tax money) or qualified (funded with pre-tax money such as through an IRA or 401k).
- Enter the total annual payment you receive from the annuity.
- If you selected non-qualified, enter your total cost basis — the total after-tax dollars you contributed to the annuity.
- If non-qualified, also enter your expected total return — multiply your annual payment by the number of years you expect to receive it.
- Enter your marginal federal income tax rate as a percentage.
- Click Calculate to see your exclusion ratio, tax-free portion, taxable portion, estimated tax owed, and net after-tax income.

The Formula Explained
Breaking Down the Formula
For non-qualified annuities, the IRS uses the exclusion ratio method. The exclusion ratio equals your total investment in the contract divided by your expected total return. Multiply this ratio by your annual payment to find the tax-free portion. The remainder is fully taxable as ordinary income.
For qualified annuities — those funded entirely with pre-tax dollars — the entire payment amount is taxable. There is no exclusion ratio because you never paid tax on those funds when you contributed them. The calculation is simple: the full payment amount is taxed at your marginal rate.
Example Calculation with Real Numbers
Suppose you have a non-qualified annuity paying $12,000 per year. You contributed $60,000 after tax, and your expected total return is $144,000 (12 years x $12,000). Your exclusion ratio is $60,000 divided by $144,000, which equals 41.67%. That means $5,000 per year is tax-free and $7,000 per year is taxable. At a 22% tax rate, you owe $1,540 in federal tax, leaving you $10,460 in after-tax income.
When Would You Use This
Real Life Use Cases
This calculator is useful any time you receive annuity income and need to understand how much of it to report on your federal tax return. It is also valuable at the planning stage — before you begin taking payments — so you can model your after-tax income and decide whether to adjust withholding or make estimated quarterly tax payments.
Tax professionals and financial planners use exclusion ratio calculations when helping clients prepare retirement income tax strategies. Running this tool yourself gives you a solid baseline before those conversations.
Specific Example Scenario
A retiree receives $18,000 per year from a non-qualified annuity. They are not sure how much to withhold for taxes. By entering their cost basis and expected return into this calculator, they discover that $7,500 of their annual income is tax-free. They only need to withhold on the remaining $10,500. This prevents them from over-withholding and losing access to money throughout the year.
Tips for Getting Accurate Results
Know Your Annuity Type Before You Start
The single most important input is your annuity type. A non-qualified annuity was funded with money you already paid income tax on. A qualified annuity was funded with pre-tax dollars through a retirement account. Check your original annuity contract or call your annuity provider if you are unsure. Getting this wrong will give you completely inaccurate results.
Calculate Your Expected Return Carefully
For the expected total return field, use your annual payment multiplied by the number of years the annuity is expected to pay out. The IRS provides life expectancy tables in IRS Publication 590-B that can help you determine the expected number of payment years if you are unsure. Using the wrong expected return figure will skew your exclusion ratio and your tax estimate.
Use Your Marginal Rate, Not Your Effective Rate
Enter your marginal federal tax rate — the rate that applies to your highest dollar of income — not your effective (average) tax rate. Annuity income is taxed as ordinary income and added on top of your other income, so the marginal rate is what applies to that additional income. You can find your marginal rate by looking at the current federal tax brackets.
Frequently Asked Questions
Are all annuity payments taxable?
Not always. Qualified annuities are fully taxable because the contributions were pre-tax. Non-qualified annuities are only partially taxable — the portion that represents a return of your original after-tax investment is tax-free. This calculator handles both types.
What is the exclusion ratio?
The exclusion ratio is a percentage that tells you how much of each annuity payment is a tax-free return of your original investment. It is calculated by dividing your total cost basis by your expected total return. The IRS requires non-qualified annuity holders to use this method to determine taxable income.
What happens after my cost basis is fully recovered?
Once you have received tax-free payments that total your entire cost basis, every subsequent payment becomes fully taxable. The exclusion ratio only applies until you have recovered your full investment. After that, 100% of each payment is ordinary income.
Does this calculator cover state taxes?
No. This calculator estimates federal income tax only. State tax treatment of annuity income varies widely. Some states exempt annuity income entirely, while others tax it at the full state rate. Check your state's tax authority website for the specific rules that apply to you.
Is annuity income subject to Social Security tax?
Annuity income itself is not subject to Social Security or Medicare payroll taxes. However, it does count as income and may affect what portion of your Social Security benefits are taxable. If your combined income exceeds certain thresholds, up to 85% of your Social Security benefits can become taxable.
Can I change how much tax is withheld from my annuity payments?
Yes. You can request a specific withholding amount or percentage from your annuity provider, or you can opt out of withholding and make quarterly estimated tax payments instead. Use this calculator to estimate your liability and then decide on the best withholding approach.
Does this apply to inherited annuities?
Inherited non-qualified annuities are taxable on the gains — the amount above the original owner's cost basis. Inherited qualified annuities are fully taxable. The rules can be complex for inherited contracts, so consult a tax professional for guidance specific to your situation.
How does this calculator handle annuity income differently from other retirement income?
This calculator focuses specifically on the exclusion ratio method used for annuities. Other retirement income types like IRA withdrawals or 401k distributions are fully taxable and do not use this same method. Use this tool only for annuity payments, and use a separate retirement income tool for other distributions.
Conclusion
Knowing your annuity taxable amount is essential for accurate tax filing and smart retirement income planning. Whether you hold a qualified or non-qualified annuity, this free calculator gives you a clear breakdown of what is taxable, what is not, and what you can expect to owe each year.
Use it annually as your payment amount or tax rate changes, and run it as a planning tool before your annuity payments begin. A clear picture of your tax exposure now means fewer surprises at filing time and more control over your retirement cash flow.
