The Time-Space Percentage Quiz

6a0133f3fc5805970b0148c813afcb970c-320wiThe Time-Space Percentage (T/S%) is the single most important number for a family child care provider to accurately calculate on  her tax return. It will make the biggest difference in reducing your taxes.

The T/S% represents the proportion of your home that is used for business purposes. You will also use it to determine how much of your shared business and personal expenses can be deducted as a business expense. Such expenses include:

House expenses: House depreciation, house improvements, house insurance, house repairs/maintenance, mortgage interest, property tax, utilities (gas, oil, electric, sewer, water, cable television, garbage) and rent.

Shared business and personal expenses: cleaning supplies, land improvements (fence, patio, driveway, underground sprinkler system), personal property depreciation (furniture, appliances, play equipment, television, etc.), toys, yard supplies, and much more.

As you can see, these deductions can amount to thousands and thousands of dollars. That’s why calculating your T/S% correctly is so important!

If an item you purchase is used exclusively for your business you can deduct 100% of the cost. But if it’s also used by your family then you can’t deduct it all. Instead, apply your T/S% to determine your business deduction. Don’t try to deduct 100% of a living room couch. If your own children only play with the item (say a toy) during day care hours, then you can still deduct 100% of the cost.

T/S% Formula

Your T/S% is determined by multiplying your Time percent by your Space percent.

Your Time percent is determined by dividing the number of hours you work in your home for business purposes by the total number of hours in the year. If you worked 11 hours a day (7am-6pm) that represents 2,860 hours a year. Divide this by the total number of hours in the year (8,760) and your Time percent would be 32.6%. You are also entitled to include all hours spent after children are gone doing business activities such as: cleaning, activity or meal preparation, record keeping, parent interviews, even reading my blog! See an upcoming blog post for more information about the Time percent.

Your Space percent is determined by dividing the number of square feet in your home that you use on a regular basis by the total number of square feet in your home. Regular use means you use it for business purposes two or three times a week. If you used 2000 of the 2200 square feet in your home regularly for your business your Space percent would be 90.9%. See an upcoming blog post for more information about the Space percent.

If your Time percent is 32.6% and your Space percent is 90.9% your T/S% is 29.63% (32.6% x 90.9%).

Enter your numbers for your T/S% on IRS Form 8829 Business Use of Your Home. As of 1/28/11 the 2010 version of this form is not yet available from the IRS. I will announce on my blog when the 2010 version has been released.

  1. If I closed my daycare last year on July 31, will I only have Jan-July hours for the year? How do I calculate my T/S % for 2012?

  2. Add up the hours you worked from Jan-July and divide them by the total number of hours in the year from Jan-July. Apply your time-space % to your expenses from Jan-July. See my article on this:http://www.tomcopelandblog.com/2012/01/how-to-claim-expenses-when-you-arent-in-business-the-entire-year.html

  3. Should I be claiming an unattched shop that stores our lawn mower, snow blower and various rakes/shovels…that the kids use? My hubby also uses this area to fix daycare items that get broken.

    • What if I only had kids before and after school? I was open all day, but didn’t end up with all-day toddlers/babies.

      • You can’t count time that you were open if no children were in your care. You can count the time children were there before and after school. If you did some business activity during the day when children were not there (cleaning, record keeping, etc.) you can count this time.

  4. Yes, I would count a shop as part of the square footage of your home. In your case you can count the square footage as being regularly used for your business.

  5. Does a depreciable basis change year to year with changing time/space %’s or is it locked in during year one (purchase year)? Example buy asset for $1000 x 20% T/S% = $200 depreciable basis. Year 2 T/S drops to 18%. Does overall depreciable basis drop to $180 or remain at $200?

  6. The depreciable basis changes each year depending on the time-space %. So, in your example, the basis for depreciate=ion in Year 2 is $180.

  7. I have a question regarding time gap in a year for child day care. My wife is currently running a licensed home day care and took a couple of months off from it. Does she need to exclude these 2 months off the entire year for the T/S% calculation? Thx!

    • You have a choice. You can exclude the two months of hours and then only claim ten months of house expenses (with a higher time-space%). Or, you can count all the hours in the year (resulting in a lower time-space%) and deduct 12 months of house expenses. I would suggest using the second method because you get a higher time-space % deduction on all non-house related expenses.
