Able to carry-over funds?

If a unit has funds remaining at the end of the calendar year, is the unit able to carry-over those funds to the next calendar year? Or, does Church HQs take back any unspent funds? Is this the same for end of each quarter as well? What happens to funds not spent at the end of a quarter? thank you

Yes. The only reason you would not have any carryover funds is if your stake has you cut them a check for your remaining 2011 balance. Once they give you the funds, they are yours and yours alone. Your 2011 ending balance is now a carry-forward balance for 2012, whether it is negative or positve. Incidentally, CHQ never took the funds back; the stake did. If it helps, I think of it as before the entire stake shared a single account and the stake told you how much of the total you could spend. If you went over, you hurt the other wards, if you went under, it remained in the account for the stake to use for budgeting the next year. Now each unit has its own account. If you go over, that's yours to recover from but if you go under, the surplus is yours to use.

At the end of the quarter, the only thing that happens is you get the funds for the next quarter. Nothing happens to your funds. You should be budgeting based on a yearly estimate, but the funds are disbursed to you in quarterly increments. Incidentally, this is how it has always been done, but most stakes did the yearly estimating for you. Now it is the ward's responsibility.

thank you!

As additional clarification, your 2011 total ending balance will appear next year as a single line item - carry-forward balance. All of your budget subcategories will begin 2012 with $0 in expenses, income and transfers. In other words, subcategory balances do NOT carry over to next year.
See this post for a recent discussion about what year-end would bring. Note my assumption was wrong in the beginning, hence I'm linking to jdlessley's clarification.

My Stake President explained it in these terms:
1) The balance would remain in the ward's individual account,
2) The stake can not remove funds from the ward's account,
3) The stake does see the balance of the ward's account,
4) The stake determines how much is deposited in the ward's account each quarter
and finally
5) Should the Stake President see a large amount accrue overtime without knowledge of any plans for those funds, he could reduce quarterly allocations. (This was his way of saying he'd like to be in the loop on plans to save for abnormally expensive events).

I've been explaining the carryover and new allocation process while referring to the parable of the talents. Those who take their talents (funds) and use them will recieve an increase. Those who feel the need to horde or hide their funds may find they will not receive future allocations.

Our stake has seen great examples of how true this principle is. The one ward that is spending all their funds has 80+% attendance in Sacrament Meeting. The wards that will end up with a carryover equal to a quarterly allocation seem to be the units that struggle with attendance.
