Use this screen to enter home office information for business activities. UltraTax CS uses this information to calculate the allowable home office deduction for a specific activity.

Electronic filing note: When entering data for electronic returns, you need to follow specific IRS guidelines to ensure that the return will not be rejected. For details, see the "data-entry guidelines" section of General and input screen-specific topics for electronic returns.

Home office information can be used with forms other than Schedule C. Use Screen 8829 to enter home office information for Schedules A, C, F, K-1, E-Rental, Form 2106, or a miscellaneous activity. UltraTax CS produces Form 8829 only with Schedule C. For the other forms and schedules, the Business Use of Your Home Worksheet is produced. UltraTax CS calculates a home office deduction for a miscellaneous activity, but the deduction does not transfer to the activity. Enter the calculated home office deduction directly on the miscellaneous activity's input screen.

Home office information entered in Screen 8829 for a K-1 Partnership activity reduces ordinary income as an unreimbursed partnership expense, and prints the Home Office Worksheet. In addition, the deduction reduces Schedule SE and other earned income calculations, if applicable.

Note: UltraTax CS provides a client-specific option to specify the method of entering asset information: either enter home office information in the asset module or in the various depreciation screens. When using the asset module for data entry, this screen is not applicable and does not appear. To enter asset information using this screen, choose File > Client Properties, click the Advanced Properties button, and clear the Enter asset detail information checkbox in the Enter Asset Detail tab. For more information about asset data entry, see Where do I enter asset data?

Source data entry

The UltraTax CS Source Data Entry utility enables you to enter data on facsimile versions of forms your clients submit for the preparation of their tax returns. Once the facsimile forms are completed, you can export the data to UltraTax CS and transfer it into your client data files via the data sharing feature. The following facsimiles are available in the Source Data Entry utility.

W-2 Series 1098 Series 1099 Series Schedule K-1 and Other

Preparers should diligently review all data that is imported through the UltraTax CS Source Data Entry utility. UltraTax CS cannot determine if amounts entered via the Source Data Entry utility duplicate data that was included in the return from another source. Do not use the Source Data Entry utility to enter data that would also be imported from a general ledger program, shared from Creative Solutions Accounting (CSA) or Accounting CS (ACS), proforma'd from prior-year information, transferred from Fixed Assets CS, or imported from a web client organizer. For more information, see UltraTax CS Source Data Entry frequently asked questions: How does data imported from other sources affect amounts entered via Source Data Entry?

Multiple 8829s with one activity

UltraTax CS allows you to enter multiple units of Screen 8829 related to one form or schedule. Two home office locations can be entered per activity.

Note: UltraTax CS does not allocate an activity's net income between two or more Forms 8829; therefore, you must enter an amount to force net income on the related activity's input screen.

Use this section to enter the general home office information.

These fields contain information about the business unit activity. UltraTax CS uses this information to gather and coordinate information for the business unit activity.

When processing a state return, enter the two-character postal code for the state to which this unit belongs. This code is used by the various state applications to help determine in-state and out-of-state amounts.

Note: A postal code entry is required for proper state processing.

See State fields in UltraTax/1040 for more information.

Enter X in this field to use the simplified method of computing the home office deduction. When marked, UltraTax CS will use the information entered in the Business Use of Home sectiion for square footage, and the activity's income to compute the simple method of home office per Schedule C, Profit or Loss from Business instructions. A nonsubmittable statement will print to support the calculation.

Note: Amounts entered for mortgage interest and real estate taxes will transfer to Schedule A.

If the client has more than one home office for the same activity, enter the number 1 or 2.

If the client has more than one home office relating to the same activity, enter a description that differentiates each office. For example, enter "Home on Baxter Road," or "Home on Main Street." You can also enter the street address of each location of the home office.

UltraTax CS calculates the business percentage based on the information in this section.

Enter an amount to override (force) the casualty loss amount calculated on Form 4684.

You may enter 0 (zero) in this field.

Carryovers are maintained in these fields rather than in Screen CO because they need to be maintained on an activity-by-activity basis.

Enter an applicable holding period for the amount entered in the Carryovers from 2012 to 2013: Casualty losses field. UltraTax CS defaults to a short-term holding period if no entry is made.

Enter those expenses that are not related to the business use of the home. Amounts entered here are reported on Schedule A, Miscellaneous deductions subject to two percent.
