How to Find Out How Much You Owe in IRS Back Taxes
You can calculate what you owe in back taxes fairly accurately without even contacting the IRS.
Finding out how much you owe the IRS in back taxes will depend on whether the tax relates to returns you’ve already filed or ones you still need to file. Either way, you can calculate what you owe fairly accurately without even contacting the IRS, though at some point, you will need to contact the agency to make payments.
Step 1: Obtain copies of all tax returns that you still owe taxes on
The first thing you'll need to do is gather all of your relevant returns and documents that relate to each year you still owe back taxes for. Each of your tax returns will report the amount of tax you owe, but never paid. If you did file a return but no longer have a copy, you can obtain one from your accountant who prepared it for you or if necessary, you can order a duplicate copy from the IRS.
Step 2: File your past-due tax returns
If your back taxes relate to returns you have yet to file, then you can calculate the amount of tax you owe for each year by preparing the actual return. However, when you do, you must use all tax forms for the year you are filing.
For example, if during 2011 you decide to prepare your 2007 tax return; then you must only use 2007 tax forms, schedules and instructions. If you mistakenly file using the forms for a different tax year, the IRS is likely to notify you of the error.
Accessing these old forms is not as difficult as you
may think. The easiest option is to use tax preparation software, such as TurboTax. TurboTax provides you with access to many of the IRS forms from prior years. Alternatively, you can search for each form you need on the IRS website. However, many of the older forms on the IRS website require you to print and fill them out manually.
Step 3: Calculate your interest and penalties
Regardless of whether you file the tax return or are preparing it for the first time this year, you must increase your tax bill for the interest and penalty charges the IRS imposes when you pay your taxes late. Calculating your penalties and interest will provide you with a more accurate estimate of what you need to pay.
For example, if you file your tax return five months or more after the original due date, then you must increase your payment by 25 percent of the tax you still owe.
Step 4: Pay your back taxes
Once you determine how much you owe the IRS, it’s in your best interest to make payment arrangements immediately. At a minimum, your outstanding back tax balance will continue to accrue interest each month it remains unpaid.
If the amount you owe is significant and you are unable to make a lump-sum payment, you should contact the IRS to work out a payment plan. Once your installment plan is in place, you can avoid more severe collection enforcement by the IRS as long as you adhere to all terms of the agreement and make each payment on time.
