I use the standard filing cabinet system with hanging files and folders. I pay nearly everything online and get online bank statements, so I don't have much paperwork to deal with.
Here's what I have in mine. The first one is the hanging file and then the items after the dash are folders inside. I also have them color-coded. Green for finances, red for vehicles, yellow for owners manuals, purple for household stuff. I'm definitely Type A...
- one folder for each of the past 7 years of income taxes
- personal property taxes
- real estate taxes
Income/Receipts (my husband needs to save this sort of stuff for tax time because of his work situation)
- one folder for paycheck stubs from each employer
- one folder for each bank account
- one folder for each investment account
Insurance (I only keep the current policy. When we get new policies, I shred the old ones and replace.)
- one folder for each vehicle
- one folder for my report and one for my husband. I get the free report for each of us every year and shred the old one.
Bills (These are odd bills that aren't paid monthly, like doctor visits for example.)
- Current Bills
- one folder per vehicle (these are things like service records, maintenance logs since we do our own oil changes and that sort of stuff)
- Household (kitchen appliances, etc.)
- Tools (my husband has a huge collection of tools, so his manuals get their own folder)
- Recipes To Try
- Recipes To File
- Restaurant Menus
And then each household member (including our dogs for vet/shot records) have their own hanging file for miscellaneous paperwork.
I probably save paperwork longer than I should. I keep owners manuals until we get rid of the item. I keep vehicle records, including loan paperwork, until we get rid of the vehicle, even if the loan is long paid. I save bank account paperwork until the account is closed. The paycheck stubs and receipts, I usually keep for 2-3 years in case we get audited.

I said at the beginning of my post that I don't have much paperwork, but it sure does seem like a lot after I list it all out!
