A pay stub can have fifteen lines on it. Most workers look at two: gross pay and net pay. Everything in between feels like a black box — money that leaves before you ever see it. But every single line on that stub means something. Some of it is taxes. Some of it is building your retirement. Some of it is covering your family's healthcare. Some of it is paying for the organization that negotiated your wage rate in the first place. Once you know what every line does, the check stops being confusing and starts being a roadmap.
Misunderstanding your paycheck does real damage. Workers who don't know how deductions work often feel cheated — by taxes, by the union, by their employer — when there's nothing actually wrong. That distrust makes it harder to make good financial decisions, because you're reacting to a misread situation instead of the real one.
Understanding your paycheck is the foundation of everything else in personal finance. Budgeting only works if you know what actually hits your account. Retirement planning only makes sense once you can see what's already being set aside. Tax planning starts with understanding what's being withheld and why. If you've ever been surprised by your take-home pay — especially after overtime or a raise — this lesson is for you.
Gross pay is everything you earned in a pay period before any deductions. For hourly workers it starts simply: your straight-time hourly rate multiplied by your regular hours. Overtime is calculated at 1.5 times your regular rate for any hours over 40 in a workweek under federal law — though some union contracts set overtime thresholds differently, and some kick in at daily overtime after 8 hours.
If you're in the trades and your rate includes a package — a total hourly rate that gets split between wages and benefit fund contributions — your gross pay may reflect only the wage portion. The benefit fund contributions (pension, annuity, health and welfare) are typically paid by the employer directly to the funds and don't flow through your personal paycheck at all. That means your total compensation per hour is higher than your gross pay line suggests. Understanding this distinction matters when you're evaluating your total earning picture.
Four tax lines appear on almost every paycheck in America:
Federal income tax — withheld based on your W-4 and your earnings for the pay period. The payroll system estimates your annual income based on that one check and applies the appropriate withholding rate. This is an estimate, not your final bill. Your true federal tax liability is calculated when you file your return each spring.
State income tax — same concept, applies in most states (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax).
Social Security — 6.2% of your gross wages up to the annual wage base ($168,600 in 2024). This funds the Social Security retirement and disability program.
Medicare — 1.45% of gross wages, no cap. This funds Medicare. High earners pay an additional 0.9% above $200,000, but most trade workers don't reach that threshold.
These four are mandatory. They can't be avoided or reduced by changing your W-4 — except for federal and state income tax withholding amounts, which you can adjust.
"My overtime gets taxed way more than regular pay — it's almost not worth it."
This is one of the most persistent misconceptions in the trades, and it is not true. Here's exactly what's happening:
Payroll systems calculate your withholding by annualizing your current paycheck. If your normal weekly gross is $1,400 and you hit a $2,200 week because of overtime, the system treats that like you're on pace to earn $114,400 for the year — and withholds federal tax accordingly, which may bump you into a higher withholding bracket for that check.
But your actual annual income didn't change that dramatically. When you file your tax return, the IRS looks at your total income for the whole year, applies your actual tax bracket, and compares what you owed to what was withheld. If too much was withheld from your overtime checks, you get the difference back as a refund.
You don't permanently pay a higher tax rate on overtime dollars. The withholding just front-loads the estimate. The true cost is simply your marginal tax rate — and for most trade workers, the marginal rate on overtime income is around 22%, meaning for every $100 in overtime earnings you keep roughly $78 after federal tax. That is always better than not earning it.
For union members, these lines represent some of the most valuable deductions on the check — even though they reduce take-home pay.
Union dues fund the operations of your local and international union: contract negotiations, grievance representation, political and legislative advocacy, training programs, and staff. Dues are typically a percentage of gross wages or a flat monthly amount. In most cases, union dues are tax-deductible as an unreimbursed employee expense — check with a tax preparer.
Pension contributions — if employee-side contributions are part of your plan — go directly into the defined-benefit pension fund and build your future monthly retirement income. Not all pension plans require employee contributions; some are fully employer-funded through your CBA package rate.
Annuity contributions go into a personal savings account in your name, separate from the pension. An annuity fund is a defined-contribution benefit — the balance is yours, it grows with investment returns, and it's typically accessible at retirement. Think of it as your union's version of a 401(k).
Health and welfare contributions fund your medical, dental, and vision coverage. These are typically employer-paid through the package rate and don't show up as deductions from your check — but they are part of your total compensation.
Vacation and holiday funds, where they exist, work as forced savings — contributions are withheld from each check and paid out to you on a schedule, creating a predictable income source during time off.
Marcus is a journeyman electrician in a IBEW local. His straight-time rate is $42.00/hour. In a recent two-week pay period he worked 80 regular hours and 12 overtime hours.
Gross pay calculation: Regular: 80 hours × $42.00 = $3,360.00 Overtime: 12 hours × $63.00 (1.5×) = $756.00 Gross pay: $4,116.00
Deductions from his check: Federal income tax (withheld based on W-4, single/1 allowance): $612.00 State income tax (estimated at 5%): $206.00 Social Security (6.2%): $255.00 Medicare (1.45%): $60.00 Union dues (1.5% of gross): $62.00 Employee pension contribution (2% of gross, if applicable): $82.00 Dental/vision premium: $18.00 Total deductions: $1,295.00
Net pay (take-home): $2,821.00
What Marcus does not see deducted but is part of his total compensation, paid by his employer directly to the funds: employer pension contribution ($5.20/hr × 92 hrs = $478.40), annuity contribution ($3.00/hr × 92 hrs = $276.00), health and welfare ($7.50/hr × 92 hrs = $690.00). These don't appear on his check but represent $1,444.40 of additional compensation that pay period.
Total compensation that pay period: $4,116.00 wages + $1,444.40 employer benefit contributions = $5,560.40. His check reflects $2,821.00. The difference is not money lost — it's taxes, retirement savings, healthcare, and dues.
Several misconceptions about paychecks lead workers to make decisions based on false premises.
I've talked to journeymen who've been in the trade for fifteen years and still couldn't tell you what their annuity fund balance was. They knew their hourly rate. They knew their take-home. Everything in between was just numbers they ignored.
Here's what I tell them: those numbers in between are your financial life. The pension contribution is building an income you'll receive for the rest of your life. The annuity is a savings account accumulating in your name. The health and welfare contribution is keeping your family covered without you paying the full freight out of pocket. Even the union dues are buying you representation, contract enforcement, and the negotiating power that produced your wage rate.
Once you understand what each line does, you stop feeling like your check is shrinking and start seeing it as a roadmap. Gross pay is what you earned. Deductions are where it went. Net pay is what's left to manage. Those three buckets cover your entire financial picture at the paycheck level.
The last thing I'll say: check your stub for errors. Contributions can be miscalculated. Deductions can be applied incorrectly. I've seen members who were under-contributing to their annuity for months because of a paperwork error nobody caught. Your stub is your record — read it.
Carlos is a journeyman pipefitter earning $34/hour. He works 44 hours one week — 40 regular, 4 overtime. His gross pay is: (40 × $34) + (4 × $51) = $1,360 + $204 = $1,564. After federal income tax ($187), state tax ($62), Social Security ($97), Medicare ($23), union dues ($28), health insurance ($85, pre-tax), and pension/annuity contributions ($95, pre-tax), his net pay is roughly $987. That is a $577 gap between gross and net. Carlos used to think something was wrong. Now he knows: $280 of that gap is going directly to benefits and retirement accounts that belong to him. Only $297 is taxes — and his pre-tax deductions reduced that tax bill by more than $40.
