Hello
I keep all receipts in envelopes marked with the month and then I tally up all the totals. I buy daycare food with our food and just mark the food for the daycare children and add this total up each month. I too put all on a spread sheet and take it to my accountant. As my accountant told a group of our daycare operators the rules and regulations change slightly each year and we may not know what we are allowed to claim and we may miss out on this deduction.
Remember to keep your records for the last 7 years, as Revenue Canada can go back that far.
