A home filing system you will actually keep needs one in-tray, four folders and one archive box, with a clear rule for how long each type of paper stays. For most renters the rules that matter are these: pay and tax records for at least 22 months after the end of the tax year if you file a Self Assessment return (five years if self-employed), and everything to do with the tenancy, especially the deposit certificate, inventory and dated photos, for as long as you live there and until the deposit comes back. Anything else gets photographed and shredded.
None of it needs a desk drawer. A wire in-tray on a bookshelf, four cardboard folders and one lidded box on top of the wardrobe is the whole system, which is about all a flat like mine has room for anyway. In a shared house each person runs their own set; the only shared bit is the tenancy folder, and one copy of that is enough if everyone knows whose room it lives in.
Why most filing systems die: too many categories
The usual first attempt is a folder for every bill, every account and every year. That comes to about eighteen folders, and the problem with eighteen folders is that every piece of paper needs a decision about which one it belongs in. Decisions are what stop you filing, so the post goes on the worktop “for now” and the system’s dead in a month.
Four folders means almost no decisions. Nearly every bit of paper that comes through the door is obviously about the flat, about money, about you, or about something you own. If it doesn’t fit one of those, it almost certainly doesn’t need keeping.
The second reason systems die is that nothing ever leaves. Paper with no retention rule piles up until the folder is too full to open. So the system needs a cull, and a cull needs a fixed date, which is why this one is tied to the end of January.
The in-tray and the fifteen-second rule for post
All post goes into the in-tray, unopened, on the way in. Not the worktop, not the table, not the arm of the sofa. In a flatshare, one tray by the door with the post standing up so names are visible beats a pile on the stairs that nobody owns. This is the only rule that has to be kept every day, and it fits into the evening walk-through of the 15-minute reset without adding to it.
Once a week, open everything in the tray and give each item fifteen seconds. There are only four outcomes:
- Bin it (marketing, envelopes, anything you can get again online).
- Do it now if it takes under two minutes (pay the thing, book the thing).
- Put it in one of the four folders.
- Photograph it and then bin or shred it.
Anything that needs more than two minutes of action goes back in the tray with a note on it, and the tray is never allowed to hold more than that week’s post plus a couple of those.
Four folders and what goes in each
Each folder is an ordinary cardboard document wallet, labelled with a marker pen. A label maker isn’t the point.
Home and tenancy. The tenancy agreement, the deposit protection certificate, the inventory and check-in report, the gas safety certificate, the electrical report if there is one, the energy performance certificate, and printed copies of any email to the landlord about repairs. Council tax and utility account letters go here too.
Money and tax. Payslips, P60s, the P45 from the last job, any Self Assessment paperwork, pension statements, bank letters that are not statements (statements are online), and anything from HMRC.
Health and ID. The passport when it is not in use, NHS letters, prescriptions that need repeating, the driving licence paperwork, birth certificate. This folder is thin and it is the one to grab first in a fire.
Things I own. Receipts for anything over about £50, guarantees, warranty cards, and the manuals you might genuinely need (the boiler, the oven). Manuals that can be downloaded stay downloaded.
That’s it. A folder for the car if you have one, a folder per child if you have those. Living with a partner, one shared Home and tenancy folder and separate Money and tax folders is the split that keeps the tax rules simple. Not a folder per account.
How long to keep tax and pay records
This is the rule people are least sure of, and I had no idea myself until I went to the source. If you send a Self Assessment return but are not self-employed, HMRC’s guidance is that you should keep your records for at least 22 months after the end of the tax year the tax return is for. Their example: if you send your 2024 to 2025 tax return online by 31 January 2026, keep your records until at least the end of January 2027. If you file late, the rule is at least 15 months after you sent the tax return.
If you are self-employed the period is much longer. HMRC says you must keep your records for at least 5 years after the 31 January submission deadline of the relevant tax year, with the example that if you sent your 2022 to 2023 tax return online by 31 January 2024, you must keep your records until at least the end of January 2029.
In practice this means: payslips and P60s for the current and previous tax year stay in the Money and tax folder; once a return has been filed for a year, that year’s bundle is clipped together, dated with the “keep until” date on a sticky note, and moved to the archive box. The box then holds, at most, two years of bundles if you are employed and about six if you are self-employed.
Tenancy paperwork: deposit certificate, inventory, dated photos and repair emails
The tenancy folder is the one that can be worth real money. Your landlord or letting agent must put your deposit in the scheme within 30 days of getting it, and you should have a certificate or confirmation saying which scheme. At the end, your landlord must return your deposit within 10 days of you both agreeing how much you’ll get back. If you don’t agree, the scheme’s dispute service decides, and it decides on evidence. In a shared house the deposit is usually one joint sum, so the photos everyone takes on move-in day protect everyone, including the person who moves out first.

Shelter’s list of what wins a dispute is short and specific. The inventory and check-out report, dated photos, and, in their words, emails showing repair problems during the tenancy and how quickly they were dealt with. On photos they note that the schemes prefer digital photos because they can check the dates and they are often clearer. So the tenancy folder is partly on paper and partly a folder on the phone, backed up, named with the flat’s address, holding the check-in photos, every photo of a repair problem, and screenshots of the emails reporting it.
A leak under the sink is the typical case: two dated photos of the damp patch, one email to the agent, one reply, and a photo of the cupboard afterwards. What to do on the day you find one is in under-sink storage that survives a leak; the paperwork from it is two sheets in the tenancy folder and a handful of photos in the phone folder.
Receipts and guarantees: photograph, then decide
Most receipts don’t need keeping on paper. A photo on the phone, filed to a folder called Receipts, is usually enough for a return or a guarantee claim, and thermal till receipts fade to nothing anyway. So the rule is: photograph, then decide.
Keep on paper only if the item is over roughly £50 and still under guarantee, or if the receipt is the only proof of a repair or a service (boiler service, bike service). Those go in the Things I own folder with the guarantee stapled to them. When the guarantee runs out, they leave at the next cull.
The January cull
Once a year, the weekend after the 31 January Self Assessment deadline, empty the four folders onto the table and go through them with the retention rules above. Allow about forty minutes. Anything past its “keep until” date is shredded (anything with an account number or address) or recycled (everything else). Anything from the past year that has finished its active life but is still inside a retention period moves to the archive box with its keep-until date written on.
January is the date because the tax rule counts from 31 January, so the arithmetic is easy: in January 2027 the 2024 to 2025 records can go if you are employed, and a sticky note on the box lid can say exactly that.
The archive box is checked once a year and opened perhaps twice. That’s the right amount of attention for paper that only matters if something goes wrong. The other systems that feed this one are in the organisation section.
