Hello Alison, thanks for reaching back out to us again at the Quickbooks Community page, we are unsure what you mean. The income tax should only be calculated for the tax year for example 23-24 if that is the tax year you are doing. If it is double what you think it should be. Do you have any amounts in the estimated income section and if so, if you can try removing it and if the income tax figure then matches what you are expecting to see? 

Please do get back to us if you have any more questions, we will be happy to answer them.
