Every month, I see the same question pop up in our WhatsApp community – “Should I use ACH or wire transfer to send money to India?”
And almost every time, the person asking has been overpaying on wire transfer fees for years. Sometimes $30-50 per transfer. Month after month.
When I was in the US, I went through the same confusion. ACH sounded like some technical banking term I didn’t need to bother with. Turns out, understanding ACH saved me hundreds of dollars every year on transfers to India.
If you’re an NRI sending money home regularly, ACH is something you absolutely need to understand. Let me break it down for you.
What is ACH?
ACH stands for Automated Clearing House.
It’s an electronic network that processes financial transactions between banks in the United States. Think of it as the highway system that moves money from one US bank account to another.
When you set up a direct deposit for your salary? That’s ACH.
When you pay your electricity bill online from your bank account? That’s ACH too.
When you authorize Wise or Remitly to pull money from your US checking account to send to India? Also ACH.
The ACH network is managed by Nacha (National Automated Clearing House Association). It processes billions of transactions every year.
In fact, the ACH network handled over 8.4 billion payments in just one quarter of 2024, worth more than $21 trillion.
It’s one of the safest and most reliable payment systems in the world. And it’s incredibly relevant for NRIs.
How Does ACH Work?
The process is simpler than you might think.
Here’s what happens behind the scenes when you initiate an ACH transfer:
- You authorize a transfer – either by entering your bank details on a service like Wise, or by setting up auto-pay for a bill
- Your bank receives the request – it gathers the transaction along with other ACH requests from customers
- Batch processing happens – unlike wire transfers that go one-by-one, ACH transactions are collected in batches and processed at set times during the day
- The ACH network routes the payment – the Automated Clearing House sorts each transaction and sends it to the right destination bank
- The receiving bank credits the account – the money lands in the destination account
The whole process typically takes 1-3 business days for standard ACH. Same-day ACH is also available now (more on that below).
ACH Credit vs ACH Debit – What’s the Difference?
This confuses a lot of people. But it’s actually straightforward.
ACH Credit (Push): You “push” money from your account to someone else’s. Your employer paying your salary via direct deposit is an ACH credit. You sending money to your parents’ account is also an ACH credit.
ACH Debit (Pull): Someone “pulls” money from your account with your authorization. When Wise debits your US bank account to send money to India, that’s an ACH debit. When Netflix charges your bank account monthly, that’s also an ACH debit.
For NRIs, the most common interaction with ACH is the debit type. You authorize a money transfer service to pull funds from your US bank account, which then gets converted and sent to India.
Why ACH Matters for NRIs
Here’s where it gets really practical.
As an NRI, you have three main ways to fund transfers to India from a US bank account:
- Wire transfer
- ACH (bank debit)
- Debit/credit card
Each comes with different costs, speeds, and trade-offs.
| Feature | ACH | Wire Transfer | Debit/Credit Card |
|---|---|---|---|
| Cost | Free or very low ($0-5) | $15-50 per transfer | 1-3% of amount |
| Speed | 1-3 business days | Same day to 1 day | Instant to minutes |
| Best for | Regular monthly transfers | Urgent, large one-time transfers | Small, urgent amounts |
| Reversal possible? | Yes, within 60 days | Very difficult once sent | Chargebacks possible |
| Hidden fees | Rare | Intermediary bank fees common | Card processing fees |
For most NRIs who send money home every month – to support parents, pay EMIs, fund investments in India, or build savings – ACH is the most cost-effective option.
Let me give you a real example.
Say you send $2,000 every month to India. If you use wire transfer through your US bank, you might pay $30-45 per transfer.
That’s $360-540 per year just in fees. With ACH through a service like Wise, your funding cost is essentially zero. You’d only pay the transfer service’s conversion fee, which is typically much lower.
That’s real money you’re saving. Money that actually reaches your family.
ACH and Popular NRI Money Transfer Services
Most of the popular transfer services NRIs use rely on ACH to pull money from your US bank account. Here’s how it works with the major ones:
Wise (formerly TransferWise)
- Uses ACH as the cheapest funding method
- Transfer fee starts around $7 for a $1,000 transfer via ACH
- Card payments cost significantly more (up to $67 for the same amount)
- Uses mid-market exchange rates with transparent fees
ICICI Money2India
- Offers ACH-based “Express Transfer” that credits your recipient in India within 4 hours
- Also has ACH-based “E-Transfer” that takes about 5 business days
- Zero transfer fee on amounts over $1,000
Remitly
- ACH bank debit is the cheapest payment option
- Express delivery (minutes) may not be available with ACH
- Economy delivery (3-5 days) paired with ACH gives the best rates
Xoom (PayPal)
- Accepts ACH bank transfers
- Can also pay via PayPal balance
- Bank deposit to India is near-instant for amounts up to ₹5 lakh
For a detailed comparison of these services, check out our Remitly vs Wise comparison guide.
The pattern is clear – whenever a service gives you the option to pay via “bank account” or “bank debit,” they’re using ACH. And it’s almost always the cheapest option.
ACH vs Wire Transfer – The Big Comparison for NRIs
This is the question I get asked most. Let me lay it out clearly.
| Aspect | ACH Transfer | Wire Transfer |
|---|---|---|
| How it works | Batch processed through the ACH network | Individually processed through SWIFT/Fedwire |
| Cost to sender | Usually free or under $5 | $15-50 (domestic), $30-50+ (international) |
| Cost to receiver | Usually nothing | Indian banks may deduct ₹100-1,500 |
| Speed | 1-3 business days (same-day available) | Same day (domestic), 1-5 days (international) |
| Transaction limits | Varies by bank ($2,000-$25,000/day typical) | Generally higher limits |
| Reversal | Can be disputed within 60 days | Very difficult to reverse |
| Best for NRIs when | Monthly family support, regular SIPs, recurring transfers | Large one-time transfers, property purchases, urgent needs |
| Works internationally? | Only within the US (but funds NRI transfer services) | Yes, directly to Indian bank accounts |
Here’s the important thing to understand. ACH itself doesn’t send money directly to India. It’s a US domestic system.
But it’s how you fund your India transfer on platforms like Wise, Remitly, or Money2India.
So the typical flow looks like this:
Your US bank account → (ACH) → Transfer service’s US account → (SWIFT/NEFT/IMPS) → Recipient’s Indian bank account
The ACH leg is cheap or free. The transfer service handles the international part and the currency conversion.
When you do a wire transfer to India directly from your bank, the flow is:
Your US bank account → (SWIFT) → Intermediary banks → Recipient’s Indian bank
Each step along the way can charge a fee. Your bank charges to send. Intermediary banks take a cut.
The receiving bank in India may charge too. Plus the exchange rate your bank offers is usually 2-5% worse than the mid-market rate.
For regular, monthly transfers to India, ACH-funded transfers through a good service win almost every time.
Same-Day ACH – What NRIs Need to Know
Standard ACH takes 1-3 business days. But same-day ACH has been available since 2016 and has grown rapidly.
With same-day ACH, your transaction is processed and settled on the same business day. Nacha has set processing windows throughout the day, and banks can choose to participate in same-day processing.
What this means for NRIs:
- Some transfer services now offer faster India deliveries when you pay via same-day ACH
- ICICI’s Money2India Express Transfer uses ACH but delivers to India within 4 hours
- Same-day ACH may come with a small additional fee (varies by service)
- Not all banks or services support same-day ACH yet
If speed is important but you don’t want to pay wire transfer prices, same-day ACH is the sweet spot.
ACH Transfer Limits
There’s no single universal ACH limit. It depends on your bank, your account type, and the service you’re using.
Here are some general ranges:
| Bank/Service Type | Typical Daily ACH Limit |
|---|---|
| Personal checking accounts | $2,000 – $25,000 per day |
| Premium/high-net-worth accounts | $50,000 – $100,000+ per day |
| Business accounts | $25,000 – $1,000,000+ per day |
| Money transfer services | Varies (Wise: up to $1M via wire, lower for ACH) |
If you need to send a large amount to India – say for a property purchase or investment – your regular ACH limit might not be enough. In that case, you may need to:
- Contact your bank to temporarily increase your ACH limit
- Use wire transfer for the large one-time amount
- Split the transfer over multiple days (be careful about any reporting requirements)
I always recommend calling your bank before making a large transfer. A quick phone call can prevent the frustration of a declined transaction.
How to Set Up ACH for Sending Money to India
Let me walk you through the practical steps. This is using a service like Wise as an example, but the process is similar across platforms.
Step 1: Create an account on a transfer service
Sign up on Wise, Remitly, Xoom, or whichever service you prefer. You’ll need to provide your identity documents (passport, US driver’s license) and complete KYC verification.
Step 2: Add your US bank account
You’ll enter your bank’s routing number (9 digits) and your account number. These are found on your checks or in your online banking dashboard.
Step 3: Verify your bank account
Most services verify your bank one of two ways:
- Micro-deposits: They send two small amounts (like $0.12 and $0.34) to your account. You confirm the amounts to prove you own the account.
- Instant verification: Through services like Plaid, you log into your bank directly to confirm ownership. This is faster.
Step 4: Add your beneficiary in India
Enter the recipient’s details:
- Full name (as per bank records)
- Bank account number
- IFSC code (find it on any Indian cheque or by searching online)
- Bank name and branch
For a detailed guide on setting up beneficiaries, check our beneficiary setup guide.
Step 5: Initiate the transfer
Enter the amount, select “Bank account” or “ACH” as your payment method, review the exchange rate and fees, and confirm.
Step 6: The ACH debit happens
The service will pull the money from your US bank account. This shows up as an ACH debit in your bank statement. The funds typically leave your account within 1-2 business days.
Step 7: Money reaches India
Depending on the service and speed option you chose, your recipient gets the money in their Indian bank account. This can range from minutes to a few business days.
Purpose Codes for ACH-Funded India Transfers
When you send money to India, you need to specify a purpose code. This is required by RBI regulations, not by the ACH system itself.
Common purpose codes NRIs use:
- P0106 – Family maintenance (most common for supporting parents/family)
- P0107 – Savings/deposits by NRIs
- P1301 – Investments under portfolio investment scheme
- P0801 – Rent/lease payments
The transfer service usually asks you to select the purpose when you set up the transfer. Pick the one that accurately describes why you’re sending the money. Getting this wrong can cause delays.
ACH Security – Is It Safe?
This is a valid concern, and I’ve seen it asked many times in our community.
Yes, ACH is very safe. Here’s why:
- The ACH network has been operating since 1972 and is regulated by the Federal Reserve
- Banks verify account ownership before enabling ACH
- Nacha rules provide consumer protection, including the ability to dispute unauthorized transactions within 60 days
- Starting in 2026, Nacha is implementing enhanced fraud monitoring requirements for all ACH participants
- Most transfer services add additional security layers like two-factor authentication and encryption
The main risk isn’t the ACH system itself. It’s the same risk that exists with any financial transaction – make sure you’re using a legitimate, licensed transfer service.
Stick with well-known names. Check that they’re registered with FinCEN in the US. Read reviews from other NRIs.

ACH and Your US Tax Obligations
ACH transfers to India aren’t taxable events in themselves. You’re simply moving your own money.
But there are some important reporting requirements NRIs should be aware of:
FBAR (Foreign Bank Account Report): If the combined balance of all your foreign accounts (including Indian NRE, NRO accounts, mutual funds, etc.) exceeds $10,000 at any point during the year, you must file FBAR (FinCEN Form 114).
Regular ACH transfers to India will increase your Indian account balances, potentially triggering this requirement.
Gift Tax Considerations: If you’re sending money to someone other than yourself (like parents or siblings), the IRS annual gift tax exclusion is $19,000 per person for 2025 and $19,000 for 2026.
Amounts above this don’t necessarily mean you pay tax, but you’ll need to file Form 709 and it counts against your lifetime exemption.
FATCA Reporting: US persons with foreign financial assets above certain thresholds must report them on Form 8938. Transfers to India increase your foreign holdings.
For a complete understanding of your US tax obligations as an NRI, check our US NRI tax filing guide.
On the India side, incoming remittances from abroad are generally not taxed. But there are nuances depending on who the recipient is and the purpose.
Gifts from close relatives are tax-free regardless of amount. Gifts to non-relatives above ₹50,000 in a financial year are taxable for the recipient.
ACH for NRIs Returning to India
If you’re planning to move back to India, ACH becomes especially important during the transition period.
Here’s why:
Before your move: You’ll likely need to transfer larger amounts to India – for a house purchase, car, setting up your new life.
Using ACH to fund transfers through a good service can save you significant money compared to multiple wire transfers.
Keeping your US bank account: Many returning NRIs keep a US bank account active even after moving.
ACH lets you continue transferring any remaining US income (rental income, pension, 401k distributions) to India affordably.
Recurring transfers: If you have ongoing US obligations (loan payments, subscriptions) or income, ACH makes automated transfers seamless.
Important: Once you become a tax resident of India (based on the 182-day rule), your tax obligations change.
But ACH as a transfer mechanism remains the same as long as you maintain a US bank account.

Common ACH Mistakes NRIs Make
After years of hearing from our community, here are the mistakes I see most often:
1. Using wire transfer for every monthly transfer
This is the biggest one. If you’re sending $1,000-3,000 monthly to parents, there’s rarely a reason to pay $30-50 in wire fees each time. Switch to an ACH-funded service and save.
2. Not checking their bank’s ACH limit before a large transfer
Nothing is more frustrating than setting up a transfer to buy that apartment in Bangalore, only to have it rejected because your bank’s daily ACH limit is $5,000. Check limits first.
3. Ignoring the exchange rate
Some NRIs focus only on the transfer fee and ignore the exchange rate. A service that charges “zero fees” but gives you an exchange rate 2-3% below the mid-market rate is actually more expensive than one that charges $5 but gives you the real rate.
4. Not setting up recurring transfers
If you send the same amount every month, set it up as a recurring ACH transfer. Many services allow this. It saves time and ensures your family gets money on schedule.
5. Funding with a credit card instead of ACH
Credit card funding typically costs 1.5-3% more than ACH. Unless you’re earning massive credit card rewards (and even then, the math usually doesn’t work), use ACH.
Understanding the Transaction Reference Number
Every ACH transfer generates a transaction reference. When you send money to India, you’ll also get a transaction reference number (also called a UTR number for India-side transfers).
Keep these numbers saved. If there’s ever a question about whether money was sent or received, these reference numbers are your proof.
I recommend keeping a simple spreadsheet with the date, amount, service used, and reference number for every transfer you make.
This also helps at tax time when you need to document the source of funds in your Indian accounts.
Frequently Asked Questions
Q: Can I use ACH to send money directly to an Indian bank account?
No. ACH is a US domestic system. You can’t use ACH to directly credit an Indian bank account. But you can use ACH to fund a transfer through services like Wise, Remitly, or Xoom, which then handle the international leg.
Q: Is ACH the same as NEFT or RTGS in India?
No. ACH is the US equivalent. India has its own systems – NEFT (similar to standard ACH, batch processing), RTGS (real-time for large amounts), and IMPS/UPI (instant payments). When your money reaches India from a transfer service, it typically arrives via NEFT or IMPS.
Q: How long does an ACH transfer take?
Standard ACH takes 1-3 business days. Same-day ACH is processed within the same business day. The total time for your India transfer includes the ACH leg plus the international transfer leg.
Q: Are ACH transfers free?
For consumers, most banks don’t charge for ACH. Some premium or expedited ACH services may have a small fee. The transfer service you use may charge their own fee on top.
Q: Can an ACH transfer be reversed?
Yes. ACH transactions can be disputed within 60 days under Nacha rules. This is actually a consumer protection advantage over wire transfers, which are nearly impossible to reverse.
Q: What’s the maximum I can send via ACH?
There’s no universal maximum. It depends on your bank and account type. Typical personal account limits range from $2,000 to $25,000 per day. You can often request a temporary or permanent increase by contacting your bank.
Q: I’m on an H1B visa. Can I use ACH to send money to India?
Absolutely. Your visa status doesn’t affect your ability to use ACH. As long as you have a US bank account, you can use ACH-funded services to transfer money to India. Many NRIs on H1B use this for regular family support.
Q: What if my ACH transfer fails?
Common reasons include insufficient funds, incorrect account details, or exceeding your bank’s limit. The money typically returns to your account within 2-5 business days. Check with your transfer service for specific failed transfer policies.
Q: Is there a new remittance tax I should know about?
Yes. As part of the One Big Beautiful Bill Act, a 1% tax on certain remittance transfers from the US took effect on January 1, 2026. However, transfers from US bank accounts (ACH and wire) are excluded from this tax. It primarily affects cash-funded transfers. This is another reason why ACH is the smart choice for NRIs.
Q: Do I need a Social Security Number for ACH?
You need a US bank account, which typically requires either an SSN or an ITIN. If you already have a US bank account, you’re good to go.
Quick Summary – When to Use ACH vs Wire Transfer
Use ACH (via a transfer service) when:
- Sending regular monthly amounts to family
- Funding SIP investments in India
- Transferring salary to your own NRE account
- Cost is more important than speed
- Amount is within your bank’s ACH limit
Use wire transfer when:
- You need to send a very large amount (property purchase, for example)
- It’s extremely urgent and can’t wait 1-3 days
- The amount exceeds ACH limits
- You want to send directly from your bank without a third-party service
Use debit/credit card when:
- It’s a small, urgent transfer
- You’re earning significant card rewards that offset the higher fees
- You don’t have ACH set up yet and need to send money immediately
Wrapping Up
ACH isn’t glamorous. It doesn’t have the “instant” appeal of card payments or the “serious banking” feel of wire transfers.
But for NRIs who send money to India regularly, it’s the quiet workhorse that saves real money over time. The kind of savings that add up to lakhs of rupees over the years.
If you’ve been using wire transfers for your monthly remittances, I’d encourage you to try one ACH-funded transfer through a service like Wise or Remitly. Compare the total amount your family receives. I think you’ll be pleasantly surprised.
