You can estimate for this current year any time. You must have last financial years details completed by June 30 next year. If you overestimated for last year you may actually get more than the 1100ish mentioned. Given your recent posts re savings due to current circs, it would be something I would strongly suggest you do sooner rather later. The last thing you want to do is put it off and find that you miss out on money that could really help you guys out at the moment

Good luck convincing dh to do it. I know it took a bit to convince dh to get his taxes up to date when we got together. But now it's very simple and straight forward for us. I book the appointment rent. He shows up whether he wants to or not lol
