Birthday dinners are one of the easiest ways to split a check wrong. The guest of honor ordered like everyone else, but they shouldn’t pay. The rest of the table agrees to cover them — then someone has to add up their share, figure out tax and tip on top, and divide that extra amount across the people who are paying.
Eva Split handles that automatically. Assign items to each person as usual, then tap the birthday person’s name. Their total drops to zero, and everyone else picks up an equal share of what they would have owed.
What “birthday person” means in Eva Split
A birthday person is someone whose entire bill — their items, their share of tax, and their share of tip — is covered by the group. It isn’t a discount on one dish; it’s the whole tab for that person, spread evenly across everyone who isn’t marked as a birthday person.
In the People section, a birthday person’s chip shows a cake icon and highlights in a different color. In Totals, they appear as birthday — covered by the group with a $0 amount due. Everyone else sees their own items, tax, and tip, plus a birthday line showing how much of the gift they’re carrying.
The problem in numbers
Three friends go out. Alex orders $30, Jordan orders $25, and Sam (the birthday person) orders $20. With no tax or tip, Sam’s friends need to cover $20 split two ways — $10 each on top of their own meals.
Add 10% tax and a 20% tip and the gift isn’t $20 anymore — it’s Sam’s $20 plus tax and tip on that $20. Eva Split includes all three when it spreads the cost, so Alex and Jordan each pay their own food and half of Sam’s full share, rounded so the table total still adds up exactly.
How to mark someone as a birthday person
Birthday marking lives in the People section at the top of any receipt. It works on AI-scanned bills and on receipts you build by hand.
- Open your receipt in Eva Split and add everyone at the table under People splitting the bill.
- Assign line items to each person — including the birthday person’s food and drinks.
- Tap the birthday person’s name chip. It switches to a filled chip with a cake icon 🎂.
- Scroll to Totals. The birthday person shows birthday — covered by the group with $0 due. Everyone else’s amount includes a birthday line for their share of the gift.
- Tap the name again to undo if you marked someone by mistake.
You can mark more than one birthday person on the same receipt — useful for a joint celebration. Each birthday person’s bill is pooled, then split evenly across everyone who isn’t marked.
Birthday vs. payment groups
These solve different problems. A birthday person is about who owes money — one person’s share moves to everyone else. A payment group is about who settles together — two or more people combine their totals onto one card without changing what each person ordered.
You can use both on the same receipt. Say a couple is treating a friend for their birthday: mark the friend as a birthday person so their meal is covered, then put both partners in a payment group so one card covers their combined total (including their portion of the birthday gift).
See our payment groups guide for combining tabs when people pay together.
What stays the same
- Item assignments don’t change — you still know who ordered what
- Tax and tip stay proportional to each person’s food and drink before the birthday adjustment
- The birthday gift includes tax and tip on the birthday person’s items, not just the menu prices
- Sharing still works — anyone with the link sees totals update live when someone is marked or unmarked
- Birthday marking is included on the free plan, along with tap-to-assign and sharing
