This is how a session goes, starting from the shock everyone gets at the first stub. Click through it.

(pastes the skill) first paycheck ever and it's way less than i calculated. did they steal from me??
Probably withholding, but let's verify instead of guessing. Open your pay stub in the payroll portal (you log in; I never do) and read me the top line: gross pay.
gross is $480. i worked 40 hours at $12 so at least that part checks out
Good: the arithmetic matches what you were told at hiring, and week one is exactly when an hours error would be worth catching. Now the lines under it. Federal income tax withheld is an estimate sent ahead to the IRS on your behalf, sized by what you put on your W-4. It's money prepaid and reconciled at tax time. What does the FICA line say?
$36.72. what even is FICA
Social Security plus Medicare: flat percentages everyone pays, 6.2% and 1.45% of gross as of recent years. Verify current rates on IRS.gov or ssa.gov rather than trusting my memory. 7.65% of $480 is $36.72, so that line checks out to the penny.
ok but there's a $12 line that just says "MEAL" and i never agreed to that
Then it goes straight on your questions list for the payroll person: any deduction you didn't agree to needs an explanation. We'll write the list together and you send it. One boundary to state plainly: I'm not a tax advisor, and when questions get specific the authorities are IRS.gov, your employer's payroll contact, and for minors a parent or guardian. Shall we label the rest of the stub?

Scripted example of a real session.

Feel dumb asking why the check is small?

Nobody is born knowing what FICA is, and the stub uses abbreviations on purpose that nobody ever explains. The goal of this session is that you can explain every line yourself, in your own words, and walk into the payroll office with a short written list of real questions instead of a vague worry. Asking "what is deduction code MEAL" in week one reads as sharp, and catching an hours error early is exactly what payroll people expect new hires to do.

What you end up with

An annotated copy of your own stub, each line labeled in plain English you wrote, plus a questions list saved where you will find it at tax time.

Example
PAY STUB  ·  NOV 1–14
Riverside Cinema  ·  Employee: A. Chen  ·  paid Nov 21
EARNINGS
Gross pay: 40.0 hr × $12.00  ·  $480.00 1
my label: "hours times rate, matches my offer"
TAKEN OUT BEFORE ME
Federal income tax  ·  $28.00 2
my label: "prepaid tax, set by my W-4, reconciled when I file"
Social Security (FICA)  ·  $29.76
my label: "6.2% of gross; rate verified on ssa.gov"
Medicare (FICA)  ·  $6.96
my label: "1.45% of gross"
State income tax  ·  $9.60
my label: "my state has one; some don't"
MEAL  ·  $12.00   ?? 3
my label: "never agreed to this. ON THE QUESTIONS LIST"
NET PAY: $393.68  ·  what actually lands
YEAR TO DATE 4
Gross $1,440.00  ·  withheld $223.08
QUESTIONS FOR PAYROLL
1. What is deduction code MEAL and did I opt in?
2. Is there a lag week between period end and payday?
3. How do I download stubs from the portal myself?
4. Who fixes it if my hours are ever wrong?
note: W-2 should arrive by January 31
  1. Check gross against your offer. Hours times rate, or the salary fraction. Errors here are rare but real, and week one is the cheapest time to catch one.
  2. Withholding is prepayment. The money went ahead to the IRS on your behalf. Whether filing gets any of it back depends on your real totals, which is a question for IRS.gov's own tools rather than for anyone's guess.
  3. Unrecognized deductions get chased. Anything beyond tax (meals, uniform, a retirement plan) must be something you agreed to. If you don't recognize it, it goes on the list.
  4. Year-to-date columns are free accounting. They answer "how much have I made and paid so far" with no spreadsheet at all.

Questions people actually ask

Will I get the withheld money back?

Maybe; it depends on your real totals for the year. Students earning little often end up owing nothing and getting withholding refunded after filing, but the skill will not promise a refund. IRS.gov's interactive "Do I need to file" tool answers it for your actual numbers, using the W-2 your employer must send by January 31.

What is a W-4 and did I fill it out wrong?

The W-4 is the form from your hiring paperwork that tells the employer how much federal tax to withhold. For a single person with one job and no dependents, the straightforward filling is usually correct. "Should I change it" is a question for the official Tax Withholding Estimator on IRS.gov, with your real numbers in it.

Does the agent log into my payroll portal?

No. You open the stub yourself, on paper or in the portal, and read the lines out. The session produces labels and questions; you keep control of every account.

My employer took out something I never agreed to. Now what?

It goes on the questions list, named by its deduction code, and the list goes to your employer's payroll contact or your manager. Deductions beyond tax must be things you agreed to, so "what is this code and did I opt in" is a completely normal question. Minors should loop in a parent or guardian too.

Is this tax advice?

No, and the skill says so whenever questions get specific. It will not compute your taxes or promise outcomes. It shows you what each line means and where the official answers live: IRS.gov, ssa.gov for FICA rates, your payroll contact, and for minors a parent or guardian.

# understand-your-paycheck

Sit with someone looking at one of their first pay stubs,
usually because the number is smaller than they expected. The goal is
that they can explain every line themselves. You are not a tax
advisor. Ask for the country and region before explaining a deduction, then
use the current official tax, social-insurance, and labor sources for that
jurisdiction. The employer's payroll contact is the authority on the stub; a
minor should also involve a parent or guardian.

## Read the stub together

Have them open the actual stub (paper or payroll portal — they log
in, you never do) and go line by line. They may read labels and totals aloud or
work from a redacted copy; do not ask them to upload identity numbers, bank
details, addresses, or portal credentials.

- Gross pay: hours times rate, or salary fraction. Check the
  arithmetic against what they were told when hired. Errors here are
  rare but real, and worth catching in week one.
- Income tax withheld: identify it using the official source for their location
  and record what payroll says it represents. Do not assume a rate or promise
  that it will be refunded.
- Social-insurance, pension, health, or other statutory deductions: verify the
  exact label and current rule on the jurisdiction's official site.
- Regional or local deductions where applicable.
- Anything else — meal deductions, uniform, retirement plan — must
  be something they agreed to. Unrecognized deductions go straight
  on the questions list.
- Net pay: what actually lands. Gross minus everything above.

Also point out year-to-date columns — they answer "how much have I
made and paid so far" without any spreadsheet.

## Find the official forms

Identify the hiring, withholding, and annual wage-summary forms used in their
jurisdiction from an official government page. Explain what each form is for,
not how they should answer tax elections. In the United States, the relevant
starting points are the IRS pages for Forms W-4 and W-2 and the official Tax
Withholding Estimator. Elsewhere, use the corresponding national and regional
authorities. The person enters every election and private number themselves.

Do not compute their taxes or promise a refund. Show them where the
official answers live and how their stub feeds those answers.

## The questions list: the artifact

Write, with them, a short list of questions for their employer's
payroll person or manager, covering whatever the stub left unclear.
Typical entries: what is this deduction code, when is payday and is
there a lag week, how do I get my stubs from the portal, who fixes
an hours error. Add a note of when their W-2 should arrive.

## Done

- An annotated, redacted copy of the stub — each line with a one-line
  plain-English label they wrote — plus the questions list, saved
  where they will find it at tax time
- Gross-to-net arithmetic reconciled or a payroll question recorded
- Jurisdiction and official sources recorded; no tax election, refund, or legal
  conclusion supplied by the agent
