What I'd tell a twenty-two-year-old about their first paycheck

The advice a twenty-two-year-old receives about their first proper job is remarkably consistent, and it's almost entirely about investing. Start early. Compound interest. Time in the market. It's true, it's well-intentioned, and it is not the thing that goes wrong.

What goes wrong is smaller and more administrative. It's a set of defaults you accept in your first week because you don't know they're decisions, and then live inside for years.

Here's what I'd actually say.

1. The number in the offer letter is not the number

The first payslip is a small shock for nearly everyone, and I think it's worth stating plainly in advance rather than discovering it.

The salary you agreed to is the gross figure. Between it and your bank account sit tax withholding, possibly a pension or retirement contribution, possibly health insurance, possibly a few smaller things. The gap between the two numbers is substantial — often twenty to thirty-five percent, depending on where you live and what you've opted into.

This isn't a problem to solve. It's just a fact to know before you sign a lease based on the wrong figure.

2. Read the payslip once, properly

Not every month. Once, at the start, line by line, until you can name every deduction on it.

It takes about fifteen minutes and it's the single highest-information document you'll receive that year. It tells you what you're paying for insurance, what's going into retirement, what's being withheld, and — critically — whether any of it is wrong. Payroll errors are more common than people expect, and they compound quietly.

You cannot notice something has changed on a document you've never read.

3. The forms in the welcome pack are not formalities

They look like formalities. They're handed to you in a stack, with a pen, by someone being friendly, in an environment where taking your time feels rude. Almost every one of them sets a default that will persist for years.

The withholding form determines your monthly cash flow. The retirement enrolment form determines your contribution rate, and the default is frequently lower than the level at which an employer match kicks in — which is the closest thing to free money you will ever be offered, and which people routinely leave on the table by accepting a default while trying to seem agreeable.

It is completely fine to say "can I take these home and bring them back tomorrow?" Employers do not react badly to this. People simply don't ask.

4. Set up the boring separation immediately

One account that receives your pay. A standing transfer, on payday, to a second account. Whatever you can manage — the percentage matters far less than the mechanism existing at all before your spending expands to fill the available space.

The reason to do it in month one is that you have no established lifestyle yet. Reducing spending later requires giving something up. Never starting requires nothing. This is the only moment in your working life where saving costs you no perceptible comfort, and it lasts about three months.

5. Learn where your tax money actually goes, once

Not in detail. Just enough to know: what is withheld, roughly how the brackets work, what filing season involves for someone in your situation.

An afternoon. One official source, not a video. The reason this matters is that a lot of financial anxiety in your twenties is really just unfamiliarity — the sense that there's a system operating on your money that you don't understand and that might, at some unspecified point, produce a bill. Knowing the shape of it removes most of that, permanently, for about three hours of effort.

6. Keep the documents somewhere findable

A folder. Digital is fine. Payslips, the annual summary from your employer, anything from a tax authority, anything from a bank about interest.

You will need these for things that have nothing to do with tax — renting a flat, a mortgage application, a visa, proving your income to someone who has no reason to trust you. The people who find this easy are not more organised; they just have a folder, made once, added to occasionally.

7. Nobody is coming to check

This is the one most worth saying directly.

There is no point at which a responsible adult reviews your financial setup and tells you it's fine. Your employer administers, it doesn't advise. The software processes what you give it. Your parents' advice is calibrated for a different decade and possibly a different country.

The whole system assumes you are managing yourself, and it will let you get it wrong indefinitely and silently. That sounds ominous but I mean it as the opposite: nothing here is difficult, the individual actions take minutes, and the only genuinely bad outcome is assuming someone else has it handled.

What I'd leave out

I wouldn't tell a twenty-two-year-old to optimise anything. Not their portfolio, not their deductions, not their tax efficiency. That advice arrives constantly and it's aimed at people with far more complexity than a first salary produces.

The gains in your first years come almost entirely from getting the defaults right and then leaving them alone: contributing enough to get the match, withholding roughly correctly, saving something automatically, keeping the paperwork. That's it. It's unexciting and it's most of the outcome.

The compound interest lecture isn't wrong. It's just answering a question you'll be better placed to ask in about five years, once the boring parts are running by themselves.
