Example of Home Office Deduction Computation
Steps for computing the home office deduction
- First, complete Schedule C.
- Check Schedule C, Line 29, Tentative profit or (loss).
- If line 29 is zero or if it shows a loss, STOP, you may not take the home office deduction or use it to increase a business loss.
- If Schedule C, Line 29 shows a Tentative profit, complete Form 8829 to compute the home office deduction.
- Enter your deduction on Line 34 of Form 8829, then carry it to Schedule C, Line 30.
- On Schedule C, subtract the home office deduction shown on line 30 from Line 29 and enter the result on Line 31.
- Finally, carry the amount from Schedule C, Line 31 to Form 1040, Line 12.
In this example, the Home Office Deduction zeros out Schedule C net profit.
The example assumes you own your home and use 20% of its total square feet for your home office (400 S.F/2,000 S.F.). In addition, Schedule C and Line 29 shows a Tentative profit $3,900
- Your first step is to complete Form 8829, Part II.
- You enter the $3,900 "Tentative profit" from Line 29 of Schedule C, on Line 8 on Form 8829.
- The first category of items subtracted from Tentative profit include:
- Total annual mortgage interest: $9,000 x 20% = $1,800
- Total annual property taxes: $2,000 x 20% = $400
- Second category of items to subtract from remaining Tentative profit:
- Insurance: $800 x 20% = $160
- Utilities: $1,200 x 20% = 240
- Last item to deduct from remaining Tentative profit:
- Depreciation on office office portion of the house: $1,400
