Saving tax for occasional RE investor with sudden big profit. Failed 1031.

[Sara Lung]

Hi,

I finally sold a piece of vacant land this January. I have $110K in capital gain, and I tried to use 1031 to buy other lands. I still have $70K capital gain left after the 6 month 1031 replacement period expired. Now I am faced with huge $20K capital gain tax next April. What to do???

I don't really want to create a complex entity, because I will probably only buy/sell 3-4 times during my life time. What to do???

I normally file 1040 tax return. What schedule(s) should I use to calculate this tax?

Thanks very much to all the great experts on this great site.
