Don't Enter Data Twice

Here at, we’ve designed our forms for so that you can fill them out quickly and easily. But taxes being what they are, sometimes it can get confusing to figure out just where is the right place to enter certain information. In fact, it’s sometimes fairly easy to accidentally double-enter information. So, in order to keep your tax return rolling right along, here are a few tips to avoid double-entering data or duplicating your deductions.

Taxes Paid

On the Itemized Deductions – Taxes Paid screen, which is part of Schedule A, there are a few opportunities to duplicate your entries. For example, we ask about state and local taxes you may have paid, but that should only be such taxes not entered on a W-2 screen or on an Estimated Taxes screen. An entry here for the same tax would double the amount.

The same caution applies for real estate taxes you paid. If you’ve entered amounts on a Form 1098 screen, don’t enter them here too.

If you have personal property taxes entered on a Form 2106, Form 8829 or a Schedule E, you won’t need the line on this form for personal property taxes.

Deductible Mortgage Interest

Another one of the Schedule A screens, the Deductible Mortgage Interest screen, uses only the figures you haven't already used. While it might make sense to enter your home mortgage interest here and on a Mortgage Interest – Form 1098 screen, if the interest is already on a 1098, don’t double it by putting it on the Deductible Mortgage Interest screen.

On the other hand, this is the form to use if you did not receive a Form 1098 for your home mortgage interest.

Overstating the State

Another area to watch out for double-entering might arise when you’re entering income for a state tax return. If your income was reported to you on a W-2, check the state and local amounts sections, lines 15–18. If this section has state income figures posted here, do not post them on another state form. That’s because knows to take these numbers and push them to your state return. If your income was from self-employment, however, and does not show up on a W-2, you might need to report the state amount on the state’s forms.

What’s the Big Deal?

So, why worry if you have duplicate figures on different forms? The biggest reason is that your return will most likely be rejected by the IRS until the oversight is corrected.

Our software will tell you – before you e-file – if you have duplicate entries on different forms and will give you the opportunity to set things straight. Even if a double entry gets through, though, you can correct and resend your return.
