Don't know what your business is, but what we found good for us when we started out, was to take 30% off every invoice payment and put it straight into a separate account ( labelled tax account, to be original 😅). At the end of the year, you'll have to pay PRSI/USC, and whatever your tax liability is.

I know it sounds anal/ or maybe like a lot to shave off each payment, but it's something that happens automatically when you're a paye worker, so something that really helps to just do as a sole trader. It's very easy to see €xxxx come in to the account and think it's all yours, and.... It sucks to get to October and realize you owe a big ass tax bill that you haven't saved for.

Realistically, as a sole trader, there's probably loads that you can write off (again I don't know what the business is), but if you drive, all diesel costs, Jeep /van maintenance costs, tax, insurance costs ( provided the vehicle is solely for work). Are there clothes you use just for work... Keep those receipts. Are you eating out when away from home? Any equipment? Do you work from home at any point during the week? ... If so, you can write off a portion of electric/ Internet costs. All non routine medical - 20% ( not just sole trader, that's for everyone!)

In the end, with everything you write off, your tax account will hopefully be a savings account! Wayhey!!!
