To keep track of receipts, you need one simple system: get every receipt into a single digital place within a day, give it a name you'd actually search for (store, item, date), and keep it only as long as it can still do something for you. For most receipts that means until the return window closes. For anything with a warranty, it means until the warranty ends.
This guide is about personal receipts: the blender, the laptop, the sofa, the jacket you're not sure about. If you run a business, you need proper bookkeeping, and I'll point to a couple of tools for that near the end.
What receipts to keep, and for how long
Most receipts have one job. Once the job is done, the receipt is clutter.
| Receipt | Keep until | Why |
|---|---|---|
| Everyday purchases | You've checked your statement | Nothing left to claim |
| Things you might return | The return window closes | Proof for a refund |
| Electronics, appliances, furniture | The warranty ends | Proof of date and ownership |
| Tax-related purchases | Your tax records period ends | Backs up a deduction |
Receipts for returns: days or weeks
Return windows vary more than you'd think, sometimes inside a single store. Target's return policy gives most items 90 days, electronics 30 days, and Apple and Beats products 14. It also says returns without a receipt "may be limited."
Apple's own US policy is 14 days from the day you receive the product, with the original or gift receipt. So don't guess: check the window when you buy, and note it with the receipt.
Receipts for warranty claims: as long as the cover lasts
For anything with a warranty, the receipt is your proof. The FTC's advice on warranties is plain: "Save your product receipt with the warranty."
The receipt, it explains, proves the date you bought the product and that you're the original owner. Some warranties also need a registration card sent in before they'll cover a repair.
In the EU, you get a minimum two-year legal guarantee from the day you receive the goods, according to the EU's Your Europe consumer site. Keep receipts for big purchases at least that long.
Taxes: years, not months
Most personal receipts never matter for taxes. The exceptions are things like charitable donations, medical costs you deduct, or improvements to a home you own. In the US, the IRS says to keep records for three years in most cases, longer in some situations, and to keep property records until the limitations period ends for the year you sell or dispose of the property.
If that applies to you, ask a tax professional what to keep.
Digital receipts: let your inbox do half the work
Most receipts now arrive by email, which is good news. They're already digital, they can't fade, and they're already searchable. If a store offers to email your receipt at the register, it's often worth saying yes.
On iPhone, the Mail app sorts messages into categories (in supported countries), and Transactions is the one for "confirmations, receipts, and shipping notices," as Apple puts it. Tap a Transactions message and you'll see every other one from that sender, so a store's whole order history is one tap away.
In Gmail, search operators do the sorting. Try category:purchases, or from: plus a store's name, or add after:2026/01/01 to limit the dates.
For the receipts that really matter, like warranties and big purchases, file them in one folder or label. Everything else can stay in the inbox.
Paper receipts: photograph them the same day
Paper is the weak link. Many receipts are printed on thermal paper, and the Australian consumer group CHOICE explains that its chemical layer stays active after printing and reacts to light, heat and friction. Its advice: the best way to keep a thermal receipt is to make a copy.
So take a photo before the receipt goes in your pocket, or at least the same evening.
On iPhone: scan it into Notes
- Open Notes and create a note, or open your receipts note.
- Tap the Attachments button (the paperclip), then tap Scan Documents.
- Hold the receipt in frame. Your iPhone captures it automatically when it finds the edges, or you can switch to manual and tap the shutter.
- Tap Done. The scan is saved in the note as a PDF.
Notes search covers text in scanned documents, so you can find it later by the store's name. A plain photo works too: Photos already gathers pictures of receipts under Collections → Utilities → Receipts.
On Android: scan it with Google Drive
- Open the Google Drive app.
- Tap Camera at the bottom right.
- Photograph the receipt, crop or clean it up, then tap Done.
- Name it, choose PDF, pick a folder and tap Save.
Google says these scans are saved as searchable PDFs.
A copy isn't accepted everywhere, so for expensive things keep the paper original too. Store it flat, somewhere cool and out of the sun.
How to keep track of receipts in one place
The rule that makes everything else work is one place. Not three apps and a kitchen drawer.
Pick something you already open every week:
- A Receipts folder in Google Drive or the Files app, with a subfolder for each year.
- A Receipts folder in Notes, with one note per purchase.
- An album in your photo app, if photos are how you capture.
Then name each receipt the way you'll search for it. Date first so it sorts, then store, item and amount: "2026-10-03 Target air fryer 89.99".
For warranty items, add the serial number and photograph the warranty card next to the receipt. And for anything you might take back, add a calendar reminder for the last day of the return window. It's the cheapest money-saving habit I know.
The same one-place idea works for things you haven't bought yet, which I covered in how to keep track of things you want to buy. It's also the backbone of organizing your digital life more generally.
How to find a receipt later by store, amount or date
This is where most systems fall apart. You remember "that blender, sometime in spring," not a file name.
- By store. Search the store's name. Notes searches the text in scans, Photos reads text inside images, and Mail searches the body of every email.
- By amount. Try the number exactly as it appears on the receipt, like 89.99. Text search often catches it, which is one more reason to put the amount in the name.
- By date. In Mail, type a month like "September" and tap the date suggestion. In Gmail, use after: and before:. Photos can search by date as well.
If your receipts live in your camera roll, my guide to searching text in photos on iPhone goes deeper, and so does finding a screenshot you took months ago.
When an app to save receipts is worth it
If you're a freelancer, or you expense work purchases, a folder isn't enough. You need receipts matched to transactions, sorted into categories and ready for your accountant.
That's the job of dedicated expense apps. Two well-known ones:
- Expensify. You can snap a photo, forward a receipt to receipts@expensify.com or upload a file, and it captures the amount, date and merchant. Its site says it's free for individuals.
- QuickBooks Solopreneur. Intuit's app for one-person businesses lets you snap photos of receipts on your phone and match them to transactions on the web.
For household receipts, they're more than you need. The free tools above cover it.
Where Reminari fits
Reminari isn't an expense tracker. It won't add up your spending or produce expense reports, so if you need those, use one of the apps above.
Where it helps is finding things: screenshot an order confirmation, or share a photo of a paper receipt from the share sheet. Reminari reads the text inside screenshots on your device, so the store name and order number become searchable. With optional cloud AI, it writes a short summary and files receipts into a Receipts smart group without you sorting anything.
Later you can ask "when did I buy the air fryer?" and get an answer from your own saves, with the receipt shown as the source. Anything sensitive can stay on your device only.
It's free to start, Android first, with iOS in active development. You can join the early-access list.
Frequently asked questions
How long should I keep receipts?
Keep everyday receipts until you've checked them against your statement, and receipts for anything returnable until the return window closes. Keep receipts for warranty items as long as the warranty lasts. Tax-related receipts need longer; in the US, the IRS says three years in most cases.
Is a photo of a receipt as good as the original?
Often, but not always. A clear photo or scan is perfect for your own records, and some stores can look up a purchase from the card you paid with. Policies vary, though, so keep the paper original for expensive items until the return or warranty period ends.
What is the best app to organize receipts?
For personal use, the easiest way to keep track of receipts is with apps you already have: Notes or Google Drive for scanning paper, and your email app for digital receipts. If you're self-employed and need receipts matched to transactions, a dedicated expense app such as Expensify or QuickBooks Solopreneur is a better fit.
Do I need a receipt for a warranty claim?
Usually you'll need proof of when you bought the item. The FTC advises saving the receipt with the warranty, because it proves the purchase date and that you're the original owner. Some warranties also ask you to register the product first.
How do I organize email receipts?
Leave most of them in your inbox and make them easy to pull up. In Apple Mail, receipts land in the Transactions category where it's available; in Gmail, search category:purchases or from: plus the store's name. File the important ones, like warranties, in a single folder or label.
