US Personal Income Taxes (+ North Carolina)
- > Educational information, NOT tax advice. This is a practical filer's [source]
- > reference, not a substitute for a CPA, enrolled agent, or tax attorney. Tax [source]
- > figures change every year with inflation, and the **One Big Beautiful Bill [source]
- > Act (OBBBA, signed July 4, 2025)** reshaped several individual provisions — [source]
- > so anything here is "as of 2026" and must be re-verified at irs.gov [source]
- > and ncdor.gov before you rely on it. Dollar thresholds below are [source]
- > date-stamped by tax year (TY): "TY2025" = the return filed in early 2026; [source]
- > "TY2026" = the return filed in early 2027. [source]
- This skill is a spoke of the consumer-finance hub (note only - do not [source]
- modify the hub). In this installation the consumer-finance family is registered [source]
- as consumer-credit-and-debt - route there for sibling topics. Neighboring [source]
- spokes are cross-referenced at the end. [source]
0. The shape of a 1040 (how the numbers connect)
- A US individual return (Form 1040) flows top to bottom: [source]
- Gross income - wages (W-2 box 1), self-employment, interest, dividends, [source]
- capital gains, retirement distributions, etc. [source]
- − Above-the-line adjustments (Schedule 1) → Adjusted Gross Income (AGI). [source]
- AGI is the pivotal number; most phase-outs key off AGI or modified AGI (MAGI). [source]
- − Standard deduction OR itemized deductions (Schedule A) → taxable income. [source]
- Apply the tax brackets to taxable income → tax before credits. [source]
- − Tax credits (some refundable, some not) → tax after credits. [source]
- − Payments (withholding from W-2/1099, estimated payments) → refund or balance due. [source]
- > TCJA note: Most of the 2017 Tax Cuts and Jobs Act individual structure was [source]
- > set to sunset after TY2025. **OBBBA made the TCJA rate brackets and the [source]
- > larger standard deduction PERMANENT** and added new (some temporary) deductions. [source]
- > The "2025→2026 sunset cliff" people feared did not happen - but several [source]
- > OBBBA add-ons (senior deduction, tips/overtime deductions) are **temporary [source]
- > (≈TY2025–2028)**, so a different uncertainty now applies. Verify any [source]
- > OBBBA-specific figure at irs.gov. [source]
1. Filing status
- Status is generally fixed by your situation on Dec 31. [source]
2. Marginal vs effective brackets (date-stamped)
- The US uses 7 marginal brackets (10/12/22/24/32/35/37%). Your **marginal [source]
- rate** is the rate on your last dollar; your effective rate is total tax ÷ [source]
- taxable income (always lower). A raise into a higher bracket only taxes the [source]
- portion above the threshold - it never lowers your take-home. [source]
- > Worked example (TY2025, Single, $60,000 taxable income): 10% on the first [source]
- > $11,925 + 12% from $11,925 to $48,475 + 22% on the last $11,525 = **≈$8,114 [source]
- > tax → marginal rate 22%, effective rate ≈13.5%.** [source]
3. Standard vs itemized deduction
Standard deduction
- > ⚠️ OBBBA retroactively RAISED the TY2025 standard deduction above the [source]
- > originally-announced Oct-2024 figures. The numbers below are the [source]
- > in-effect, OBBBA-revised amounts (IRS Rev. Proc. 2025-32 supersedes the [source]
- > earlier figures). An old TY2025 source showing $15,000/$30,000 is pre-OBBBA. [source]
- Additional standard deduction for age 65+ OR blind (per condition; a [source]
- person 65+ and blind gets it twice): TY2025 $1,600 (married, per box) / [source]
- $2,000 (unmarried); TY2026 $1,650 / $2,050. [source]
Itemize instead if your total exceeds the standard deduction
- Schedule A buckets: SALT (state/local income or sales + property tax - note [source]
- OBBBA raised the SALT cap above the old $10,000; verify the current cap and [source]
- income phasedown at irs.gov), mortgage interest, charitable gifts, [source]
- medical expenses over 7.5% of AGI. Itemizing is common for homeowners in [source]
- high-tax areas; renters rarely beat the standard deduction. [source]
4. Common credits (more valuable than deductions — $-for-$)
- A deduction lowers taxable income; a credit lowers tax dollar-for-dollar. [source]
- Refundable credits can pay you beyond zero tax; nonrefundable only zero [source]
- out tax owed. (Figures TY2025 unless noted.) [source]
- > Don't confuse the Child Tax Credit (per child, on Sch. 8812) with the [source]
- > Child & Dependent Care Credit (for daycare/care costs so you can work, on [source]
- > Form 2441) - they're different credits and you can claim both. [source]
5. Above-the-line adjustments (reduce AGI even if you take the standard deduction)
- These come off gross income before AGI, so they help everyone and shrink [source]
- MAGI-based phase-outs: [source]
- > Retirement-account strategy and contribution mechanics (Roth vs [source]
- > traditional choice, backdoor Roth, employer-match optimization) are **out of [source]
- > scope - route to a dedicated retirement/investing skill if one is installed.** [source]
- > Briefly, on the tax side only: traditional = deduct now / taxed at [source]
- > withdrawal; Roth = no deduction now / tax-free qualified withdrawals. HSA and [source]
- > IRA appear here only as the AGI-reducing line items. [source]
6. W-4 withholding & refund-vs-owe
- Your employer withholds tax from each paycheck based on the Form W-4 you file. [source]
- The redesigned W-4 (post-2020) eliminated "allowances" (they were tied to [source]
- personal exemptions, which TCJA zeroed out). It's now a 5-step form: filing [source]
- status (Step 1), multiple-jobs/working-spouse (Step 2), dependents/credits [source]
- (Step 3), other income / deductions / extra withholding 4(c) (Step 4), [source]
- A big refund ≠ winning - it means you over-withheld and gave the [source]
- government an interest-free loan all year. Owing a lot can trigger an [source]
- underpayment penalty. The goal is to land near $0. [source]
- Tune withholding with the IRS Tax Withholding Estimator [source]
- (irs.gov/individuals/tax-withholding-estimator), which outputs a pre-filled W-4. [source]
7. W-2 vs 1099, self-employment tax & quarterly estimated taxes
- > Boundary: this section is for an individual filer with 1099 / gig / [source]
- > freelance income filing a personal return. If your question is about owner [source]
- > taxes because you formed an entity (LLC/S-corp/sole-prop entity choice and [source]
- > its self-employment-tax consequences), that's venture-nc-business-formation-tax. [source]
- W-2 (employee): employer withholds income tax and pays half of your [source]
- Social-Security/Medicare (FICA); you do nothing extra. [source]
- 1099-NEC (independent contractor / gig / freelancer): no withholding, no [source]
- employer FICA match - **you owe self-employment tax and must make your own [source]
- quarterly payments.** (Worker status is decided by IRS common-law rules — [source]
- behavioral/financial control & relationship; misclassification is a real risk.) [source]
Self-employment (SE) tax
- Rate 15.3% = 12.4% Social Security + 2.9% Medicare, charged on 92.35% [source]
- of net SE earnings; kicks in at $400 of net earnings. [source]
- The 12.4% SS portion applies only up to the SS wage base: **$176,100 [source]
- (TY2025) / $184,500 (TY2026)**; the 2.9% Medicare portion has no cap. [source]
- 0.9% Additional Medicare Tax on wages/SE income over **$200k Single / [source]
- $250k MFJ / $125k MFS** (static - Form 8959). [source]
- You deduct one-half of SE tax above the line, easing the sting. [source]
Quarterly estimated taxes (Form 1040-ES)
- Who: anyone expecting to owe $1,000+ at filing after withholding [source]
- (typical for self-employed, large investment income, or under-withheld W-2). [source]
- Safe harbor (avoids the underpayment penalty - pay the smaller of): [source]
- 90% of this year's tax, OR 100% of last year's (**110% if prior-year [source]
- Four due dates (TY2026 cycle): Apr 15 2026, Jun 15 2026, Sep 15 2026, [source]
- Jan 15 2027 (next business day if a weekend/holiday). Penalty figured on [source]
8. Capital gains (brief — tax treatment only; route strategy to a retirement/investing skill)
- When you sell an asset (stock, crypto, property), gain = **amount realized − [source]
- basis. Basis** = what you paid, adjusted for things like improvements or [source]
- reinvested dividends. [source]
- Short-term (held ≤ 1 year): taxed as ordinary income at your [source]
- Long-term (held > 1 year): preferential 0% / 15% / 20% rates. [source]
- TY2025 long-term breakpoints (taxable income): 0% up to $48,350 Single / [source]
- $96,700 MFJ; 15% above that to $533,400 / $600,050; 20% beyond. [source]
- Net Investment Income Tax (NIIT) 3.8% adds on top once MAGI exceeds [source]
- $200k Single / $250k MFJ (static - Form 8960). [source]
- Reported on Schedule D + Form 8949. Capital losses offset gains and up [source]
- to $3,000 of ordinary income per year (excess carries forward). [source]
9. The IRS process: deadlines, extensions, fixes, audits, paying late
- > A 1099-C (canceled debt) that shows up as taxable income - and the [source]
- > insolvency exclusion / Form 982 - is **cross-referenced, not covered here [source]
- > → charge-offs-collections-and-debt-resolution. Likewise tax-related [source]
- > identity theft (someone files using your SSN), the IRS IP PIN**, and [source]
- > Form 14039 → identity-theft-and-credit-fraud. [source]
10. Free filing (verify current — status changed in 2025)
- IRS Free File - public-private partnership: brand-name guided software [source]
- free if AGI ≤ $89,000 (FS2026 figure; was ~$84k the prior year). [source]
- Free File Fillable Forms are available at any income. **Still [source]
- operating.** → irs.gov/freefile [source]
- IRS Direct File (the IRS's own free direct-to-government e-file tool) — [source]
- > ⚠️ As of 2026: NOT available. The IRS told its 25 partner states in [source]
- > Nov 2025 that "Direct File will not be available in Filing Season 2026," [source]
- > the app/pages are down (directfile.irs.gov refuses connection; the old IRS [source]
- > pages 404), and the Jan 2026 filing-season notice omits it. Note: **OBBBA [source]
- > §70607 funded a study of a public-private replacement (a $15M task force, [source]
- > 90-day report) - it did not itself order termination;** the shutdown was a [source]
- > separate IRS/Treasury administrative decision. **Re-verify at irs.gov before [source]
- > relying** - its future is unsettled. [source]
- Other free options: MilTax (military) and VITA/TCE (free [source]
- in-person prep for lower-income, elderly, limited-English filers). [source]
11. North Carolina individual income tax (flat rate)
NC flat rate (date-stamped) — NCDOR / G.S. 105-153.7
NC standard deduction (TY2025)
Where NC differs from federal (filer-facing)
- Starts from federal AGI, then applies NC adjustments → NC taxable income × [source]
- flat rate. No personal exemptions. [source]
- Social Security / Railroad Retirement: NOT taxed by NC (deduct on D-400 [source]
- Sch. S if in federal AGI). [source]
- Bailey settlement: certain federal/state/local & military retirement [source]
- benefits are NC-exempt if the retiree had **5+ years of creditable service [source]
- as of Aug 12, 1989.** [source]
- Capital gains: taxed as ordinary income at the flat rate - NC has no [source]
- preferential long-term rate (gains already sit in federal AGI). [source]
- NC itemized deductions are limited (mortgage interest + property taxes [source]
- combined capped at $20,000; plus charitable, medical, claim-of-right) — [source]
- narrower than federal Schedule A. [source]
- NC 529 contributions: no NC contribution deduction (earnings/qualified [source]
- withdrawals are still NC-tax-free). [source]
NC child deduction (a DEDUCTION, not a credit) — TY2025
- Per qualifying child (one for whom you get the federal CTC), tiered by filing [source]
- status and federal AGI; phases to $0 at higher AGI. [source]
- > NC BUSINESS taxes - entity income, sales/use, franchise, NC withholding, [source]
- > employer payroll - are out of scope here. Forming a NC entity / business [source]
- > tax → venture-nc-business-formation-tax; running payroll / NC withholding [source]
- > as an employer → venture-nc-employer-payroll. [source]
