I have/had consulting business for more than 5 years (along with working as an "employee" for another firm). Tax-wise there's always been a profit (SE income), but much/most of it was actually put into a SE-401K (my reguarly employer doesn't have a retirement plan). In fact the maximum contribution was placed in the 401K SE every year. Because my regular wage income was over the SS limit (no 12.4% ss tax), except for the medicare (2.9%), a total ~15K +20% profit was contributed every year (nice deal).
However in 2008 I will have a loss. In fact I will have no new revenue on a cash-basis this year (no 1099 income). This loss is due to the fact that I was paid in advance in Dec 2007 for consulting to be performed in 2008; with the taxes on these funds therefore paid on my
2007 return. The estimated amount of the loss is relatively small, but significant (~ $5K).Is part of the 2008 business loss deductable against other 2008 income? I also understand that you can (or may be required) to carry forward part/all of the loss to be deducted against future business profits. I also understand that it may be possible to carry back the loss against prior years to get a a more immediate benefit.
My two questions are:
1) What is the quick summary of how a loss is handled (I checked the relevent IRS pub and it seems very complicated) in terms of what it can be deducted against.2) How does the loss and how it is handled (especially it is applied to past years), effect past 401K contributions? For example if it possible to get a credit for the loss based on past year's profits does this method effect the allowable 401K contribution for that past year the loss is applied against requiring some adjustment/withdrawal of/from the 401K ?
