How to Read Your Payslip: Every Deduction Explained
Most people glance at exactly one number on their payslip: the amount hitting their bank account. Everything above it — the alphabet soup of deductions, the YTD columns, the codes nobody explained — gets ignored.
That’s a shame, because your payslip is the most detailed financial document you receive regularly. Understanding it helps you catch errors, optimize your taxes, and finally answer the eternal question: where does all my money go before I even see it? Let’s decode every line.
The anatomy of a payslip
Every payslip has the same skeleton, regardless of employer:
- Pay period and pay date. The dates you worked vs. the date you’re paid. Useful for budgeting — a “previous month” pay date means your January budget runs on December work.
- Gross pay. Your total earnings for the period before anything is removed: salary or hourly wages, plus overtime, bonuses, and commissions listed separately. This is the number your salary negotiation was about.
- Deductions. Everything subtracted — taxes, benefits, retirement. This section is where we’ll spend most of our time.
- Net pay. Gross minus deductions. Your take-home pay. The number that funds your actual life.
- YTD (year-to-date) columns. Running totals since January 1st for each line. These matter enormously at tax time and for tracking progress toward retirement contributions.
Every deduction, explained
Federal income tax withholding
This is the IRS’s cut, estimated from your W-4 form. It’s called withholding because it’s a prepayment, not your final bill — the real calculation happens when you file your return, and you either get a refund (you overpaid) or owe more (you underpaid). Big refund every year? That’s an interest-free loan to the government; consider adjusting your W-4.
FICA: Social Security and Medicare
FICA is the payroll tax, and it has two parts:
- Social Security: 6.2% of wages up to an annual cap (adjusted yearly; your employer matches another 6.2%). Once your YTD earnings pass the cap, this deduction stops for the rest of the year — which is why high earners see a nice “raise” late in the year.
- Medicare: 1.45% of all wages, no cap. High earners pay an additional 0.9% above a threshold.
Unlike income tax, there’s no refund or reconciliation here — FICA is simply the price of the social safety net.
State and local taxes
Varies wildly. Some states have no income tax (hello, Texas and Florida); others take a significant bite. You may also see city or county taxes, state disability insurance (SDI), or paid family leave contributions, depending on where you live. If you moved mid-year, check that the right state is withholding — this is a classic error.
Pre-tax deductions (these lower your taxable income)
These come out before income tax is calculated, which means they shrink your tax bill:
- 401(k) / 403(b) contributions. Your retirement savings, reducing taxable income dollar for dollar (traditional contributions). Check the YTD total against the annual IRS limit — and against your employer match.
- Health, dental, and vision premiums. Your share of insurance costs, usually pre-tax.
- HSA contributions. If you have a high-deductible health plan, HSA contributions are triple tax-advantaged: deductible going in, tax-free growth, tax-free withdrawals for medical expenses.
- FSA contributions. Pre-tax money for medical or dependent care expenses — but remember, most FSAs are use-it-or-lose-it each year.
- Commuter/transit benefits. Pre-tax dollars for public transit or parking, if your employer offers them.
Post-tax deductions (these don’t lower taxable income)
- Roth 401(k) contributions. You pay tax now, withdrawals are tax-free in retirement. Often the right choice in your lower-earning years.
- Life/disability insurance premiums (beyond basic employer coverage).
- Union dues, garnishments, or wage attachments.
- Charitable giving through payroll deduction.
Common payslip mistakes to check for
Spend five minutes per pay period verifying these — errors are more common than you’d think:
- Wrong tax withholding after life changes. Marriage, a new baby, a second job, or a move all change your correct withholding. Update your W-4; don’t wait for a surprise at tax time.
- Missing employer 401(k) match. If your employer matches contributions, verify the match actually appears. Payroll glitches happen.
- Benefit premiums that never dropped off. Left the dental plan at open enrollment? Make sure the deduction actually stopped.
- PTO/vacation balance errors. Not money today, but paid time off has real value — and balances sometimes fail to accrue correctly.
- Overtime or bonus miscalculations. If your pay varies, reconcile hours against your own records at least quarterly.
Budget on Net Pay, Not Gross
Your budget should run on take-home pay — the number after all these deductions. Enter your net pay in the free budget calculator for a realistic 50/30/20 split.

FAQ
Why is my bonus taxed at a higher rate than my salary? It usually isn’t, quite — bonuses are typically withheld at a flat 22% federal rate, which can look higher than your regular withholding. But withholding isn’t your tax rate. When you file, all income is taxed together in your actual brackets, and any over-withholding comes back as a refund.
What’s the difference between gross pay and net pay? Gross pay is everything you earned before deductions — the number on your offer letter. Net pay is what’s left after taxes, benefits, and retirement contributions — the amount deposited in your account. Your budget must be built on net pay, because that’s the money you actually have.
Why did my net pay change when my salary didn’t? The usual suspects: benefit premiums changed at open enrollment, you hit the Social Security wage cap (the 6.2% stops for the year), you changed 401(k) contributions, or payroll processed an updated W-4. The YTD columns usually reveal which line moved.
What does YTD mean on my payslip? Year-to-date — the running total of that line since January 1st. YTD gross pay shows total earnings so far; YTD federal withholding helps you estimate your tax refund or bill; YTD 401(k) contributions show progress toward the annual limit and your employer match.
