The Taxpayer Advocate Service has developed several tools for individuals and employers to assist in estimating their ACA related credits and payments. Because these tools provide only an estimate, you should not rely upon them as an accurate calculation of the information you will report on your tax return. You should use these estimators only as a guide to assist you in making decisions regarding your tax situation.

The Premium Tax Credit Change Estimator can help you estimate how your premium tax credit will change if your income or family size changes during the year. This estimator tool does not report changes in circumstances to your Marketplace. To report changes and to adjust the amount of your advance payments of the premium tax credit you must contact your Health Insurance Marketplace. Be sure to report all changes directly to that Marketplace because they can affect both your coverage and your final credit when you file your federal tax return.

The Individual Shared Responsibility Payment Estimator can help you estimate the amount you may have to pay if you did not have minimum essential coveragea during the year. This tool can only provide an estimate of your individual shared responsibility payment. To determine the payment when you file your tax return, use the Shared Responsibility Payment Worksheet in the instructions for Form 8965.

The Small Business Health Care Tax Credit Estimator can help you determine if you might be eligible for the Small Business Health Care Tax Credit and how much credit you might receive. This tool provides you with an estimate for tax year 2014 and beyond. However, some figures used in determining the credit are indexed for inflation. Because of this, for future years, the estimator cannot provide a detailed estimate.

The calculations provided by the TAS Estimator Tools are only estimates and may not match the actual credits or payments you will report on your tax return. IRS cannot validate the accuracy of the estimator calculations for your specific circumstance.

TAS is an independent organization within the IRS whose job is to ensure every taxpayer is treated fairly and that taxpayers know and understand their rights.
