I do it all. Husband would have no idea who our insurance policies or gas/electricity is with, and wouldn't have a clue what our monthly outgoings are. His salary goes into the joint account and he hasn't even bothered to download the banking app. He's always been disorganised and a "that'll do" type, whereas I'm very organised and a perfectionist. I'd be surprised if he could tell you who even provides our home insurance, whereas I could tell you the premium and renewal date off the top of my head. Along with everything else - life insurance, pet insurance, household bills. It's just the way I'm wired. So rather than force DH into doing something "properly", I find it's easier to just do it myself. Probably not very PC but it causes me a lot less stress in the long run.
It did take years for me to come to the realisation though. Years of nagging and hand-holding - all taking much longer than the task itself would have. Just because I thought DH should do "his share" on principle. Once I accepted that the old adage of "if you want a job done properly, do it yourself", I found things much less stressful.
I tend to 'delegate' things to DH because he would never volunteer to do things. I do the food shopping list, he does the actual shop. I notice we're running low on dog food, I ask him to go and buy it. I book the cars in for their services and MOTs, he takes them. Sometimes I get annoyed at the lack of "proper division" of tasks and the sheer amount of mental admin I do, while he just sits back and waits for his next instruction. But I try to remember it's ME who wants the full food shop where nothing gets missed - DH would happily go to the shop twice a day every day as things ran out. It's ME who doesn't want the dogs to run out of food. DH would happily chuck them a biscuit and leave them stood waiting for their dinner while he went and bought more. I want to get the best price for insurance, TV and broadband etc, DH would just leave everything the way it was and pay the extra. It would not bother him one jot if we missed someone's birthday or ran out of washing powder.
The same goes for cleaning. As a perfectionist I like things clean and tidy, and for things to be done in a certain way and to my standards. DH would be perfectly happy to live in a pig sty, as would DS. Crumbs, spills, hairy floors, dirty bathrooms - it simply doesn't bother him. He is perfectly happy to go out wearing un-ironed clothes, I like everything ironed. So rather than quietly seethe that he never "offers" to clean up or do any ironing, I just do it myself.
For YEARS we had a passive aggressive ongoing situation about hair gel. Every fecking morning I'd go into the bathroom and the stuff would be sitting on the windowsill where he'd just used it and left it for the fairies to put away. I would huff and puff and put it away in the wall cabinet literally two feet away. Next day, there it is again. He saw me do it sometimes, complete with passive aggressive slamming of the cabinet door. After literally years of getting more and more annoyed about it (and possibly had a touch of PMT), one day I snapped and dragged him into the bathroom, pointed at the tube with a shaky finger and spat out through gritted teeth "why the FUCK can't you PUT your pissing hair gel AWAY?". He just looked at me a bit bewildered and sheepishly said "But I keep it on the windowsill, it's where it goes. Every day you move it and I have to get it out the cabinet before I can use it. I thought you were maybe just doing it to annoy me" 
Now I realise there are two types of people in this world. People who think everything should be tidied away into cabinets because it's "better". And people who consider it ridiculous to hide things you use every day behind a door, when there's a perfectly good windowsill to clutter up
