Key takeaways
- In law a proprietor and the business are the same person, but mixing their money makes tax returns, GST credit and loans harder.
- Run all business receipts and payments through a business current account, and pay yourself through recorded drawings.
- Cash has strict limits under income tax law, such as the disallowance of most cash payments above Rs 10,000 to a person in a day.
- Split mixed-use costs like a car, phone or home office on a reasonable basis, and keep the working.
A sole proprietorship is not a separate legal person. The business is you, and its income is your income. That is exactly why so many proprietors run everything through one bank account and one wallet. But mixed money causes real problems: you cannot show a lender what the business earns, your GST and income tax figures stop matching, and a simple tax query turns into weeks of explaining every deposit. This guide explains how to separate personal and business transactions in a proprietorship, in practical steps.
Why separation matters even though the law treats you as one
- Cleaner tax returns: your income tax return should show business income that ties back to your sales and bank records.
- GST reconciliation: sales in your GST returns should match receipts in the business account. Personal deposits mixed in look like unreported sales.
- Loans and credit: banks read your business account statements to judge repayment capacity.
- Future conversion or sale: if you later move the business into an LLP or company, or sell it, clean records make valuation and transfer far easier.
Step 1: open a business current account
Open a current account in your business name and route every business receipt and payment through it. Keep a separate UPI ID or QR code for business collections. Banks need two documents in the business name, such as Udyam, shop and establishment or GST registration. Our guide on the business bank account for a proprietorship lists what banks accept.
Step 2: pay yourself through drawings
Decide a fixed monthly amount you will take for personal needs, and transfer it from the business account to your personal account. In your books this is recorded as drawings, which reduce your capital in the business. It is not an expense, so it does not reduce your taxable profit.
When you put personal money into the business, record it as capital introduced. These two entries, capital and drawings, are what keep a proprietor's books honest.
Step 3: keep personal bills out of the business account
School fees, home EMIs, family insurance and household shopping should be paid from your personal account. If a personal payment slips through the business account, record it as drawings rather than as an expense. Personal expenses are not deductible from business income.
Step 4: respect the cash limits
Income tax law puts firm limits on cash, and the Income-tax Act, 2025, which applies from 1 April 2026, continues them under new section numbers:
| Rule | What it means for you |
|---|---|
| Cash payments for expenses | A business expense paid in cash above Rs 10,000 to one person in a day is generally disallowed (Rs 35,000 for payments to transporters for plying, hiring or leasing goods carriages) |
| Cash receipts | You must not receive Rs 2 lakh or more in cash from one person in a day, for one transaction, or for transactions relating to one event; the penalty can equal the amount received |
| Loans and deposits in cash | Taking or repaying a loan or deposit of Rs 20,000 or more in cash is not allowed |
Keep a cash book for the cash you do handle, deposit sale proceeds in the bank regularly, and prefer digital payments. For proprietors using presumptive taxation, digital receipts also matter, because the higher turnover limit applies only when cash receipts stay within 5% of total receipts.
Step 5: split mixed-use costs sensibly
Some things serve both home and business: a car, a mobile phone, an internet connection, a room used as an office. Claim only the business share, worked out on a reasonable basis such as kilometres travelled, floor area or time used, and keep a note of the working. Under GST, input tax credit is not available on goods or services used for personal purposes, and credit on most passenger cars is blocked altogether.
Step 6: pay family members properly
If your spouse or children work in the business, you can pay them for the work they actually do. Keep the payment reasonable for the work, pay it through the bank and keep a record of their role. Payments to relatives that are excessive for the work done can be disallowed.
Step 7: reconcile every month
- Download the business bank statement.
- Match every receipt to a sales invoice or record its source.
- Match every payment to a bill or mark it as drawings.
- Check that sales in your books match your GST returns.
- Update the cash book and count the cash in hand.

Frequently asked questions
Is it illegal for a proprietor to use one bank account for everything?
No law makes it illegal as such, but banks may restrict business use of savings accounts, and mixed accounts make it hard to prove which receipts are business income. That invites questions from the tax department and slows down loans.
How should a proprietor pay themselves?
By drawings: transfer a fixed amount from the business account to your personal account and record it as drawings. A proprietor cannot pay a deductible salary to themselves, because you cannot employ yourself.
Can I pay business expenses from my personal card?
Yes, occasionally. Keep the invoice in the business name, with your GSTIN if you want input tax credit, and record it as capital introduced or reimburse yourself from the business account.
Can I claim part of my home rent as a business expense?
If you genuinely use part of your home for the business, a reasonable share of rent and electricity can be claimed. Keep a note of how you worked out the share, such as the floor area used.
