Tipping & Gifting Rules, Sourced

Emily Post calls the year-to-send-a-gift deadline a rumor and gives you three months. The Knot prints the year. Here is what each one actually says, and what to do about it.

Chabad is explicit that flowers mean nothing to the dead, and that you are not expected to bring anything at all. Here is what the tradition actually asks for instead, and why the same gesture becomes a donation rather than a bouquet.

Emily Post calls the old rule self-serving and keeps it as the default. Babylist calls it obsolete and says so in print. Both are quoted here, and what actually decides it now.

Massachusetts caps a class gift to a teacher at $150 a year — but the regulation attaches a second condition nobody checks: the teacher can never be told who gave what. A gift under the limit that breaks that condition isn't exempt either.

Chai, the Hebrew word for life, carries the numeric value 18 — which is why gifts of money at a bar or bat mitzvah customarily land on 18, 36, 54, 90, or 108. The reflexive $100 doesn't divide by 18, so it carries none of the symbolism.

The federal aid formula counts a dependent student's own assets at 20% with no protection allowance, versus 12% after an allowance for a parent-owned 529. A $500 check sitting in the graduate's own account can raise what the formula expects them to pay.

Delta Dental's national tooth fairy figure rose 17% in a single year, and one region's number rose 52%. Its own methodology note explains why: a poll of 1,000 parents with a ±3% margin of error swings that much on its own, no real price change required.

Every page on this subject repeats the same $25 classmate figure, printed by Reviewed in February 2023 and never dated by anyone who quotes it. Federal price data shows it's already worth about $27 — and the $100 ceiling for a close friend's child is closer to $110.

The etiquette authority everyone cites for the $10-$20 bottle rule also publishes two situations where a dinner guest doesn't need to bring anything at all — close friends who host each other often, and large formal parties in general.

Every other year in the gift reciprocity calculator averages twelve months of federal price data. 2025 averages eleven, because the government shutdown suspended CPI collection for October and the data cannot be recovered.

Federal law bars an employer, a manager or a supervisor from keeping any of it. What you cannot see from the counter is whether your tip tops up a wage or replaces one — and why that should not change what you press.

A binding estimate guarantees the price; a non-binding one only guarantees that the mover cannot demand more than 110% of it at the door. Both are federal, and neither one moves the crew's tip.

Your mail carrier, a public school teacher, your boss if you are both federal employees, and any wedding vendor whose contract already includes gratuity. Four rules that cap the answer before the arithmetic starts.

Since May 2025, federal rule requires a hotel to disclose what a mandatory fee is for before you pay. It does not require the fee be small, refundable, or connected to a tip — and almost none of them are.

DoorDash's own fee page names a delivery fee, a service fee and a small-order fee, then says of the one thing that isn't theirs: every dollar you tip goes to the Dasher. Federal law backs that second sentence and has nothing to do with the first three.

A payment counts as a tip only if you chose to pay it and set the amount yourself. A mandatory 15-20% line your caterer added to the contract fails both tests — which means it's the vendor's revenue, and reaches the staff only if they say so in writing.

A compulsory service fee on your check is the salon's revenue under federal wage law, not a tip. A genuine tip has its own protection against being skimmed by an owner or manager — one that quietly stops applying the moment the person in the chair is renting it, not employed.

Japan's tourism board says plainly that tipping isn't the custom for restaurants, cafes, taxis and hotels — not as an etiquette rule, but because Japanese wages were never built around a tip filling in the gap the way American tipped wages are.

IRS Publication 517: an offering made out to a minister personally is taxable income to them; the same check made out to their church isn't. Same afternoon, same $440 envelope, and about $62 of difference decided by one line you write.

Federal law lets a sitter do some housework without becoming your employee — up to 20% of the hours worked, 48 minutes on a four-hour evening. Past that line, on that same evening, the casual-babysitting exemption stops applying.

The IRS decides this by who controls the work, not by how much you pay. Book through a service and you can spend $10,000 a year and owe nothing; direct-hire and direct the work yourself, and $3,001 makes you a household employer.

Federal ethics rules cap what a supervisor may accept from a subordinate at $10 of non-cash items per occasion — and that ceiling is per person receiving it, not per person chipping in, so a pooled office gift breaks it fast.

Emily Post's own wait-service rows say "15-20%, pre-tax" — not just a percentage, but a base. Tipping on the total printed at the bottom of the check tips the sales tax along with the meal, and the gap grows with the local tax rate.

Assign rooms to maximize value, then split what's left over the rent equally — it works for two roommates and can fail from three up. A published proof and a worked $2,400 example show one roommate can end up envying another's room by $80 a month.
