How to compute the limitation
The limitation only applies to business credits and does not apply to the following credits:
Earned income tax credit
Young child tax credit
Foster youth tax credit
Credit for household and dependent care
Credit for elective tax under the Small Business Relief Act
Credit for adoption costs
Renter’s tax credit
Personal exemption credit
Credit for qualified joint custody head of household and a qualified taxpayer with a dependent parent
Credit for qualified senior head of household
Credit for low-income housing
Excess contributions of unemployment compensation
The credits listed above are required to be applied after any business credits are applied.
For each taxable year of the limitation, taxpayers may make an irrevocable election to receive an annual refundable credit amount, in future tax years, for business credits disallowed due to the $5,000,000 limitation. The election must be made annually by completing form FTB 3870 and attaching it to an original, timely filed tax return.
If a taxpayer does not choose to make the election outlined above, business credits disallowed due to the limitation may be carried over. The carryover period for disallowed credits is extended by the number of taxable years the credit was not allowed.
Taxpayers are required to keep track of the disallowed business credits on a worksheet and provide it to the Franchise Tax Board upon request.
