How to Track Expenses Without Saving Every Receipt: Bank CSV Import Explained

Quick Answer

You don't need to photograph every coffee receipt or manually type every transaction. Most banks let you export your transactions as a CSV file, which you can then import into expense tracking tools. The tool categorises your spending, calculates monthly totals, and handles duplicates—so you get organised records with minimal effort.

The Receipt Problem (and Why Bank Exports Solve It)

Every self-employed person knows the struggle:

Pockets full of crumpled receipts
Faded thermal paper that's illegible after a month
A shoebox of "I'll sort this later" paperwork
Forgetting to record small purchases

But here's the thing: your bank already has a record of every transaction. Every card payment, every transfer, every standing order—it's all logged with dates, amounts, and merchant names.

By exporting this data as a CSV (a simple spreadsheet format), you can:

See all your spending in one place
Filter and categorise transactions
Calculate totals automatically
Keep digital records for HMRC

What Is a CSV Export?

CSV stands for "Comma-Separated Values." It's a universal format that looks like a spreadsheet—rows of data with columns for date, description, amount, etc.

Every major bank offers CSV downloads:

Bank	How to Export
Monzo	App → Account → Export → CSV
Tide	Web dashboard → Transactions → Export
Revolut	App → Accounts → Statements → Excel/CSV
Starling	App → Statements → Download CSV
Barclays	Online banking → Statements → Export
Lloyds	Internet banking → Download transactions
HSBC	Online banking → Transaction history → Export

The exact steps vary, but the concept is the same: download your transactions as a file you can use elsewhere.

Step-by-Step: From Bank Export to Organised Expenses

Step 1: Download Your CSV

Log into your bank (app or website) and find the export/download option. Choose:

Date range: The period you want (e.g., last month, last quarter)
Format: CSV (not PDF—you need the data, not a picture of it)

Save the file somewhere you can find it.

Step 2: Import Into an Expense Tracker

Open your expense tracking tool and upload the CSV. Good tools will:

Detect the columns automatically (date, description, amount)
Let you map columns if needed (different banks use different layouts)
Show you a preview before importing

Step 3: Categorise Transactions

Most tools auto-categorise based on merchant names:

Merchant Contains	Suggested Category
SHELL, BP, ESSO	Fuel
AMAZON, ARGOS	Equipment/Supplies
UBER, TRAINLINE	Travel
ADOBE, DROPBOX	Software
TESCO, SAINSBURYS	Possibly personal (flag for review)

You can:

Accept the auto-categories
Change individual transactions
Set rules for future imports

Step 4: Filter Business vs Personal

If you use one bank account for everything (not ideal, but common), you'll need to separate business and personal transactions.

Filtering options:

Import expenses only (exclude income)
Exclude keywords (e.g., "NETFLIX", "SPOTIFY")
Set business use percentage (e.g., phone is 60% business)

Step 5: Review and Confirm

Check the totals make sense. Then import. Your monthly expense figures are now ready.

Handling Duplicates

What if you import the same month twice? Or overlapping periods?

A good import tool uses deduplication:

Each transaction gets a unique fingerprint (date + amount + description)
If you try to import a duplicate, it's skipped
You see how many were new vs. already imported

This means you can safely re-import without creating mess.

Monthly and Quarterly Totals

Once your transactions are imported, you get automatic totals:

Monthly view: See each month's expenses at a glance
Category breakdown: How much went on travel vs. software vs. office supplies
Running totals: Year-to-date figures that update as you add data

These totals feed directly into your tax estimate, so you can see how expenses reduce your bill.

Do You Still Need Receipts?

The bank export proves the transaction happened. But HMRC can ask for proof of what you bought (the receipt).

When Receipts Matter

VAT claims: If you're VAT-registered and reclaiming VAT
Large purchases: Equipment, assets, significant expenses
Unusual items: Anything that might raise questions
HMRC enquiry: They can ask for evidence for any claim

Practical Approach

You don't need to keep every paper receipt. But do:

Photograph receipts for significant purchases (phone camera is fine)
Keep digital invoices (email receipts from online purchases)
Save confirmations for subscriptions and services

For small, routine business expenses (coffee with a client, parking), the bank record plus a brief note is often sufficient.

Common Questions About Bank CSV Imports

"What if my bank doesn't offer CSV export?"

Almost all banks do—check the website rather than just the app. If truly unavailable, you might need to manually enter transactions or switch to a more modern bank.

"Can I import from multiple banks?"

Yes. If you have a Monzo for daily spending and a Tide business account, import both. The tool combines them.

"What about cash expenses?"

Cash transactions won't appear in your bank export. You'll need to:

Add them manually
Keep receipts (especially for cash)
Consider going cashless for easier tracking

"Is this secure?"

CSV files contain transaction data, so treat them carefully. Don't email them around. Most expense tools use encrypted uploads. The data doesn't include your login credentials.

FAQ

Do I need to keep paper receipts if I have bank CSV imports?

For most expenses, the bank record is strong evidence. But keep receipts (digital or paper) for large purchases, anything unusual, or if you're VAT-registered.

Can I import from credit cards?

Yes, if your credit card provider offers CSV export. Most do through online banking.

What about expenses paid by someone else?

If you reimburse someone (or they pay business expenses on your behalf), you may need to add these manually. The bank export won't show them.

How far back can I import?

Most banks let you export at least 12 months, often more. Check your bank's data retention policy.

Will this work for MTD quarterly updates?

Yes. Your monthly totals can be grouped into quarters, making quarterly updates straightforward.

What if I use accounting software already?

You can use both. Some people prefer lighter tools for expense tracking and export summaries to their main accounting system.

Is categorisation accurate?

It's based on merchant names and keywords—usually 80-90% accurate. You'll want to review and correct a few items each month.

Can I edit transactions after import?

Yes. Change categories, adjust business use percentages, or delete transactions that shouldn't be there.

Next Steps

Stop chasing receipts. Start using the transaction data your bank already has.
