How to Manage Receipts Before Year-End Tax Settlement
Why You Always Lose Out When You Leave It All Until Year-End
If you dig through a year's worth of receipts in December, two things slip through the cracks. First, paper receipts that have faded or gone missing. Second, supporting documents that get omitted because you no longer remember what the money was spent on. If the deductions or refunds you miss every year amount to tens or hundreds of thousands of won, that is not laziness. It is the cost of not having a system.

Sort Receipts into 3 Groups by Storage Value
| Category | Examples | Handling method |
|---|---|---|
| Deduction and proof | Medical expenses, education expenses, donations, rent proof | Photograph and store in a folder; keep for 1 year |
| Warranty and exchange | Appliances, electronics, expensive household goods | Store separately with a note of the purchase date |
| Record only | Coffee, meals, small expenses | Enter only the amount in your household ledger and discard |
Trying to collect every receipt wears you out. If you keep only 'deduction and proof' and 'warranty and exchange' receipts, then record only the amounts for the rest and throw them away immediately, 90% of the paper disappears.
A 5-Minute Monthly Receipt Routine
- Fix the same day each month, such as payday, as your 'sorting day.'
- Divide the receipts collected during the month into the 3 groups above (2 minutes).
- Photograph deduction and warranty receipts with your smartphone and upload them to folders such as '2026_medical_expenses' or '2026_warranties' (2 minutes).
- Use a consistent file name format: 'date_item_amount' (for example, 0609_dentist_85000).
- After confirming the photos, discard the paper receipts, and reflect record-only receipts only in the household ledger total (1 minute).
For example, if your annual medical expenses are 1.2 million won and you photograph each monthly 100,000 won expense as it happens, all you need to do in December is open the folder and check the total. The time spent searching for scattered paper drops to 0.
Rules to Follow When Digitizing Receipts
- Thermal-paper receipts fade over time, so photograph them on the day you receive them.
- Keep the photos in two places, your phone and the cloud, in case the device is lost.
- Cash spending is hard to prove. For items that may qualify for deductions, use a payment method that leaves a record whenever possible.
Year-end tax settlement is not an event that starts in December. It is the result of what you have accumulated since January. Five minutes of sorting each month can prevent both an 8-hour year-end scramble and missed refunds.
Do Not Try to Collect Every Receipt
Receipt management fails when you try to keep everything. Keep only what is needed for year-end tax settlement, warranties, or exchanges, and record only the amounts for the rest before clearing them out. This reduces the burden. What matters is not piling up paper, but making sure you can find what you need later.
For photographed receipts, category-based folders are often more convenient than monthly folders. At year-end, what you need is not all of June's spending, but category totals such as medical expenses, education expenses, and donations.
