Here are mine. I am aware I am anal about this. Don't care. At least it will give other people ideas.
Taxes - I try not to overpay Uncle Sam that much. Would rather keep the money. But I also put some aside so if we do owe, we already have it. Pluses: tax returns are mostly instant (just have to wait for some of it), make a puny amount of interest (better than 0) on it all year.
Heating Fuel - We aren't on a monthly plan. This includes oil and wood, as we have both heating systems.
Auto Insurance - Now I pay in full, then as soon as I pay I contribute to this sinking fund for the next year's premium.
Medical - To cover deductibles.
Dental - We don't have dental insurance, so this has to cover everything.
Life Insurance - Same deal as auto insurance.
Auto - Covers maintenance, both planned (oil changes, rotating tires and whatnot) and unplanned (repairs).
Pharmacy - DH gets a prescription every 3 months online and I put aside some each month for it.
Airfare - Annual airfare to visit my parents.
Water/Sewer - Quarterly city bill.
Trash - Annual sticker for the dump, $50
Car Excise Tax, Registration - Blah blah
Gifts - Covers our Christmas and birthday gift obligations
Veterinarian - Blah blah
X's Wedding - Special one-time fund for a friend getting married later this year, to cover my airfare, hotel, transportation and wedding gift.
Home - Maintenance
New Car - We're not shopping for a new car in the foreseeable future, but sometime in the next, oh, 20 years we'll probably need a new one. This fund is unfortunately underfunded, but hey, it's something.
Bulk - A little set aside to take advantage of bulk deals should something great pop up.
Homeschooling - Books and all.
CSA - I try to set some aside every month, even the ones I don't have to make a payment.
