Bond Investing: A Complete Walkthrough

A ground-up guide to bonds — what they are, how the market prices them, and how the picture changes once Georgia municipal bonds enter the mix.

A bond is a loan. You give an issuer — a government or a company — money now; they pay you interest on a schedule and return your principal at a set date. Five terms carry the whole subject:

Three yield figures you’ll see quoted:

• Coupon yield — the fixed rate, meaningless once price moves off par
• Current yield — coupon ÷ current price
• Yield to maturity (YTM) — the real number that matters: total return if held to maturity, accounting for price paid vs. par received, plus all coupons

Three tax filters apply to muni interest, and you need to check all three:

1. Federal — interest is exempt from federal income tax. Full stop, always true for munis.
2. Georgia state — only exempt if the bond is issued by Georgia or a Georgia political subdivision (state, Gwinnett County, Georgia cities, Georgia school districts, Georgia authorities). A California or New York muni is federally exempt but must be added back to Georgia taxable income — you lose the state benefit entirely.
3. Capital gains — if you buy a bond below par and later sell it (or it’s called) for more than you paid, that gain is taxable — the tax exemption only covers the interest, not price appreciation. This also applies if you buy a muni at a market discount and hold to maturity; the discount portion can be taxed as ordinary income under “de minimis” rules. This is a real trap for first-time muni buyers who assume “muni = no taxes on anything.”

Example: a Georgia muni yielding 3.5%, if your combined federal + Georgia marginal rate is roughly 32%, is equivalent to a 5.15% taxable bond. If you can find a taxable corporate bond or CD paying more than 5.15% at similar risk, the muni isn’t actually the better deal — the tax exemption doesn’t automatically win. Always run this math before assuming munis are optimal; it’s the step most first-time muni investors skip.

Given your stated goal — steady tax-advantaged income, specifically the Georgia state benefit — this comparison points toward individual Georgia munis as the structurally correct tool, not a preference, just what the math and mechanics support. Funds are the easier on-ramp but don’t deliver the state-specific benefit you’re after.

If buying individual munis — Schwab only (Robinhood doesn’t offer individual bonds)

1. Log into Schwab, go to Fixed Income → BondSource.
2. Filter: bond type = Municipal, state = Georgia, and set your maturity range (e.g., 5–10 years) and minimum credit rating (Part 6).
3. Review each offering’s details before buying — CUSIP, coupon rate and maturity date, YTM and YTC (yield to call, if callable), credit rating (Moody’s/S&P), GO vs. revenue bond, call provisions (many munis are callable — the issuer can repay you early if rates drop, cutting your income stream short; check the call date/price), and minimum lot size (typically 5 bonds / $5,000 face value for new issues).
4. Read the Preliminary Official Statement (POS) for the specific offering — the bond’s prospectus, covering the issuer’s finances and the specific revenue pledge if it’s a revenue bond.
5. Place the order — new issues have no added commission; secondary trades are $1/bond online ($10 min / $250 max).
6. Settlement: municipal bonds typically settle T+1 or T+2. Interest usually pays semi-annually and lands in your account automatically.
7. Track it going forward: Schwab lets you set credit rating change alerts — useful since a downgrade mid-hold changes your risk profile even though your coupon doesn’t change.

If buying muni funds/ETFs — either platform

1. Pick a fund — for GA tax purposes, a national muni ETF (like MUB) still gets you the federal exemption but not the Georgia one, since most of its holdings are non-GA.
2. Buy shares like a stock — no minimum beyond one share, no POS to read, no call-date tracking required (the fund manager handles it).
3. Distributions typically pay monthly, not semi-annually, and the amount will fluctuate slightly as the underlying portfolio turns over.

• Interest rate risk — bond prices fall when rates rise. Irrelevant if you hold an individual bond to maturity; unavoidable in a fund.
• Credit/default risk — the issuer’s ability to pay. Municipal default rates are historically low, especially for GO bonds, but not zero (Detroit, Puerto Rico are the cautionary examples, though Puerto Rico bonds carried unusual risk from the start). Check credit ratings; investment-grade is BBB−/Baa3 or higher.
• Call risk — issuer repays early when rates drop, forcing you to reinvest at lower rates. Check call provisions before buying.
• Liquidity risk — selling an individual muni before maturity, especially a small odd lot, can mean a worse price than the market’s “real” value. This is a reason many advisors suggest only buying individual munis you’re prepared to hold to maturity.
• Concentration risk (Georgia-specific) — deliberately buying only Georgia issuers for the tax benefit means your muni portfolio is geographically concentrated. If Georgia’s fiscal picture deteriorated broadly, that would hit your whole muni sleeve at once. Worth weighing against the tax savings.
• Inflation risk — fixed coupon payments lose purchasing power over time; munis don’t protect against this the way TIPS do.

Playing this straight, since you asked for the full picture:

1. Run the taxable-equivalent yield math (Part 3) against current Schwab BondSource Georgia offerings before buying anything.
2. If the math holds up, start on Schwab, not Robinhood — it’s the only platform of the two that gives you individual Georgia muni access.
3. Consider a small starter ladder (e.g., 3–5 Georgia GO bonds across different maturities) rather than one large position — this limits call risk and concentration in any single issuer.
4. Keep the position sized as a distinct “income sleeve,” separate from your active trading capital, given the very different risk/return purpose it serves.
