What to Write on the Memo Line of a Check: 40+ Examples to Copy

3 min read · Updated October 13, 2026 · By the Check Writer 123 team

The best memo is short and specific: a reference number, a month or a few words that say what the check pays for. Below are more than forty examples you can copy, grouped by situation. If you only want the basics first, read what the memo line on a check is.

A simple formula for any memo

When you are stuck, use this order: what it is, then the reference, then the period. For example, Invoice 2210, March. That covers most bills in three words, and the person who receives the check can match it without asking you.

Memo examples for rent and housing

  • July rent
  • August rent, Unit 12
  • Rent, 41 Oak Street, September
  • Security deposit
  • Pet deposit
  • Last month's rent
  • Late fee, October
  • HOA dues, Q3

Memo examples for business payments

  • Invoice 10482
  • Invoices 3310 and 3311
  • PO 7781
  • Office supplies, March
  • Monthly service, April
  • Deposit, design project
  • Final payment, project 204
  • Equipment repair
  • Shipping and freight
  • Account ending 3921

Memo examples for payroll and contractors

  • Pay period ending 10/15
  • Wages, week of 9/30
  • Bonus, Q2
  • Reimbursement, mileage
  • Subcontractor, framing, job 118
  • Progress payment 2 of 4
  • Materials, roofing job

A memo is a note, not payroll records. Keep the real payroll figures in your payroll system, and use the memo only to label the check. Check Writer 123 prints the check and keeps a register, and it does not calculate wages or taxes.

Memo examples for taxes, insurance and loans

  • 2026 estimated tax, Q4
  • Property tax, second half
  • Insurance premium, policy ending 4417
  • Loan payment 5 of 24
  • Account ending 8830
  • Registration renewal

When a government agency or lender asks for specific wording or a number in the memo line, use exactly what they ask for. That is the one case where the instructions on the bill override a style guide.

Memo examples for donations, schools and gifts

  • Building fund
  • General donation
  • In memory of M. Hale
  • Spring registration
  • Class trip
  • Happy birthday
  • Wedding gift
  • Thank you

Memo examples when you want the line left simple

Sometimes the right memo is nothing. If the payee already knows what the check is for, or you track the detail in your own register, a blank memo line is fine. A cluttered memo is worse than an empty one.

What never to write on the memo line

  • A full account, credit card or Social Security number
  • Passwords, PINs or security codes
  • Medical, legal or family details
  • Anything you would not want a stranger who handles the check to read
  • Words such as paid in full, unless you truly mean to settle the whole debt

Using memo examples when you print checks

If you print your own checks, you can reuse the same wording every month and the memo prints in the correct place each time. With check printing software you type the memo once on the check form, see it in the live preview and find it again later by searching your register.

Frequently asked questions

What do you write on the memo line of a rent check?

Write the month and, if you have more than one unit, the unit number, such as July rent, Unit 4B. If your landlord asked for a tenant or account number, add the last digits of it.

What do you put on the memo line for a business check?

Use the invoice number, the purchase order number or a short description with the month, such as Invoice 10482 or Office supplies, March. A consistent habit makes it easy to match the check to your records.

What do you write in the memo line for a gift?

Something short and friendly, such as Happy birthday or Wedding gift. You can also leave it blank.

What do you write in the memo line for taxes?

Follow the agency's instructions. If none are given, write the tax year and the type of payment, such as 2026 estimated tax, Q4. Never write your full Social Security number on a check.

Can I leave the memo line empty?

Yes. The memo is optional, and a check with a blank memo line is valid.
