Home Office while taking standard deduction

[Indraniwaty]

Took 30% on mortgage interest & real estate tax. Can we claim 70% on Excess Mortgage Interest & Excess Real Estate Tax?

Form 8829
Line 10 and Line 11
Line 16 and Line 17

You cannot deduct the other 70% of your mortgage interest and real estate tax.  You can take 30% (if that is your business % on line 7) of the total amount of mortgage interest and real estate tax you paid on the property where your home office is located.  Excess interest and tax would occur if you were itemizing and your deductions for state and local tax and mortgage interest were limited to due the caps on those deductions.  In that case, you could take 30% of the excess (i.e. the disallowed amounts).
