Made me look.
I had a large transition last year - coming out of semi-retirement and taking a job, moving overseas, selling my house, my car, etc....I now rent but that cost is covered by an allowance. Nevertheless, rent is a big chunk of change around here.
Both years' taxes are my largest expense; I spent almost 35% less this year than last, still taxes tends to be 25-35% of the amount. I tend to travel a lot - that has been shot to he!! around here. I did buy some nice pieces of furniture, but that didn't even make up the difference from last year. I also was in the hospital last year over here and after that ordeal, the bills kept coming as most of the lab work, specialist support/etc, in the hospital were out of network, so I paid out-of-pocket.
My second highest 'expense' was tax deferred and Roth max-outs. I also took advantage of my SEP IRA withholding amounts.
This year, the biggest check I will write is for the Roth conversion taxes owed. That will be repeated over the next few years....
Nevertheless, as I review this year and the last few, I am a very fortunate person financially. My mistakes both in investing and personally that affected my financial situation have been absorbed and I am still in a great position. My goal next year is to max out the Roth, tax defer to the matching only and then shovel more into the Roth again from the tax deferred. That will mean not maxing out tax-deferred so that cash in the checking account can cover the check at the end of the year to Uncle Sam.
My other goal is to pack 25 lbs of vacation and traveling fun into a 5 lb bag while I am still here - my list has definitely grown....and my friends are waiting as well to join me.
