Yes, you can print your own deposit slips. No federal law forbids it, and nothing in the Uniform Commercial Code requires you to use forms issued by your bank. The practical question is whether the slip you produce will pass through your bank’s automated sorting equipment, which means using magnetic ink, the correct paper, and precise formatting. For most individuals the equipment cost outweighs the savings; for businesses processing frequent deposits, it can pay off.
Is It Legal to Print Your Own Deposit Slips
UCC Article 4 governs bank deposits and collections in every state and doesn’t mandate bank-issued forms.1Cornell University. UCC – Article 4 – Bank Deposits and Collections What it does do, under Section 4-103, is let banks and customers agree to their own processing standards as long as those standards aren’t “manifestly unreasonable.”2Cornell University. UCC 4-103 – Variation by Agreement, Measure of Damages, Action Constituting Ordinary Care In everyday terms, a teller or an automated reader-sorter can reject a slip it can’t process, and repeated rejections may lead the bank to require its own forms going forward.
Before spending anything on supplies, call your bank. Ask two questions: does the bank accept self-printed deposit slips, and what specifications does it require? The answer varies by institution, and it’s cheaper to find out over the phone than after you’ve bought a printer cartridge.
What a Deposit Slip Has to Contain
Every slip carries the same core data, whether it came from a bank or your own printer. Getting any field wrong can misroute your funds or flag the deposit for review.
- The nine-digit routing transit number for your bank, which appears at the bottom left of your checks.3American Bankers Association. ABA Routing Number
- Your account number, copied exactly from a check or your online banking profile. A single transposed digit sends the deposit somewhere else.
- The bank name and branch address, which act as a secondary check for teller-processed deposits.
- The account holder’s full legal name as it appears on the account.
Verify each number against a voided check or your bank’s portal before you save the template. What the MICR line encodes has to match what the bank has on file.
What You Need to Print One That Scans
MICR Toner
Ordinary laser or inkjet toner won’t work. Banks run deposit slips through high-speed reader-sorters that detect a magnetic signal, not just visible ink.4Thomson Reuters. Add MICR Numbers to Check and Deposit Slips Magnetic Ink Character Recognition toner contains iron oxide particles that produce that signal. Print with a standard cartridge and the characters will look right to you but be invisible to the bank’s equipment.
A MICR cartridge runs roughly $160 to $270 depending on the printer model. That is workable for a business printing hundreds of slips a year and hard to justify for a household making a few deposits a month.
Printer and Paper
Use a laser printer. Laser toner bonds to the page with heat, producing a crisp, smudge-resistant image that survives automated handling. Inkjets smear and don’t accept MICR cartridges. Paper needs to be heavy enough to feed through sorting machines without jamming or tearing. Multi-part carbonless commercial deposit forms typically use 20-pound stock, and single-part slips should be at least that weight. Some banks prefer heavier paper, so confirm before ordering a ream.
Dimensions and MICR Placement
Deposit slips are smaller than letter-size paper, so set custom page dimensions in your software. The recommended size is roughly 7 1/8 to 7 5/8 inches long by 3 to 3 1/4 inches wide.5Indiana State Comptroller. Wells Fargo MICR Document Design Specifications The MICR clear band occupies the bottom 0.625 inches of the slip, and nothing else magnetic should appear inside it.6ANSI Webstore. ANSI X9.100-160-1-2009 Magnetic Ink Printing (MICR) Part 1 – Placement and Location If your routing or account number drifts even slightly outside the band, the reader-sorter rejects the slip.
Printing and Testing the Slip
You need software that can position the MICR line accurately. Many accounting programs ship with deposit slip templates built to banking dimensions. Standalone check-printing programs offer similar layouts where you enter your routing number, account number, and bank information into designated fields.
Do a test print on plain paper first. Lay it next to a bank-issued slip or measure with a ruler to confirm the MICR characters sit inside the bottom 5/8-inch band and appear in the correct sequence. Each character should be sharp and fully formed. Faint or broken characters fail the magnetic read.
Once the alignment checks out, load your deposit-weight paper and print the batch. Inspect for streaks, smudges, or faded characters. If the output looks inconsistent, clean the transfer roller and reprint. A single bad slip can cost more time than the batch saves.
When Self-Printing Actually Saves You Money
The economics work at scale and not much below it. A MICR cartridge runs $160 to $270 and prints several thousand pages, on top of the cost of a laser printer and specialty paper. For a business generating dozens of deposits a week, per-slip cost eventually drops below a penny and on-demand printing is genuinely convenient. For an individual, the numbers don’t add up.
Compare that to the alternatives:
- Banks typically charge $40 to $75 for a book of 50 to 100 personalized pre-printed deposit slips.
- Third-party printers sell compatible books starting around $20 to $25 with faster turnaround than most banks.
- Counter slips at your branch are free. You write your account number in by hand, and they work fine for occasional in-person deposits.
- Mobile deposit through your bank’s app skips slips entirely. You photograph the check, funds usually post the next business day, and daily limits commonly run around $5,000.
- Most modern ATMs accept cash and checks without a slip or envelope, scanning and counting them on the spot.
Security and Record-Keeping If You Do Print Your Own
Self-printing puts your routing and account numbers in a file on your computer and potentially in your printer’s memory. That’s exposure that doesn’t exist with a book of slips in a drawer. If the template lives on a shared network or a laptop that leaves the house, anyone with access has what they need to move against the account. Password-protect the file, encrypt the drive on portable machines, and clear printer memory after use. The FTC has documented fraudsters buying check stock at office supply stores and using accounting software to produce fake checks drawn on stolen account numbers, so treat your templates the way you’d treat a checkbook.7Federal Trade Commission. Anatomy of a Fake Check Scam
For a business, self-printed slips are part of the tax record. The IRS lists deposit slips as supporting documents showing amounts and sources of gross receipts, and expects them kept organized by year for at least three years after the return they support. Retention stretches to six years if income was underreported by more than 25 percent and has no limit for a fraudulent or unfiled return.8Internal Revenue Service. Publication 583, Starting a Business and Keeping Records One advantage of self-printing is that your accounting software can store a digital copy alongside each transaction, though the IRS still expects orderly physical files.
