I attach my food receipts to the backs of my weekly menu's. I highlight all of the items that I purchased and used for that week's food, and then I tally it up. I then have a separate sheet where I keep track of my weekly food expenses. At the end of the year, I just add them up. =) If you use a spreadsheet program (Excel) you can use your computer - I'm an old school kind of gal here. For toys, I have a separate sheet. Again, I keep all the receipts in an envelope. On the sheet I record when I bought the toy, from what store I bought it, what item it is and how much it wa. Every month or so I tally up my spending, and at the end of the year I add everything up. I like this system because it allows me to keep an eye on how much I'm spending on my program. i.e. I spend 77 dollars a week on food (on average) It keeps my budget on track, and it lets me know if I need to increase my rates. (due to food prices increasing I had to raise my rates last year) I also have a final sheet where I keep my Enbridge/Hydro/Home Insurance/Water & Sewar bills. I write off a percentage of these every year (see CRA website for details on how much you can write off) Other caregivers I know also keep their property tax paperwork handy, and their monthly mortgage statements at hand - you are permitted to write off a certain amount of your home if you are using it for daycare. i.e. do you have a designated play area just for the daycare babies, or do you have a room that they use exclusively for sleeping ? Hope that this helps, and don't fret overly. I found that the taxes were pretty straightforward to do, and as long as your not deliberately trying to defraud the system the folks at CRA are very reasonable. I find that CRA tends to get a bit of a harsh rap - they're not big, old meanies. If you make an honest mistake on your taxes (my sister did in her first year as a caregiver) they'll let you know and you just fix it up (either by clarifying details or paying up)Good luck !
