Buying a car in the District of Columbia is not “sticker price plus sales tax.” The District charges a motor vehicle excise tax based on fair market value, unladen weight, and city miles per gallon—or a separate electric-vehicle column. Title, lien, registration, and inspection fees sit on top of that tax. This guide explains how a DC auto loan estimate is built from official government figures only, and which numbers you must enter yourself because no public agency publishes them.

Whether you shop at a District dealer, buy from a private seller, or title a car you purchased across the river, the payment on your contract depends on what DMV treats as fair market valuewhich cell of the weight-and-MPG table applies, and whether you roll those government charges into the loan. The following pages walk through each piece with real dollar examples so you can check a calculator or a dealer worksheet before you sign.

If you have already used a DC auto loan calculator online, this article shows what should be happening behind the monthly payment—and why treating the District like Maryland, Virginia, or Georgia produces the wrong tax.

What Makes the District Different From Maryland and Virginia

Most Americans think of car tax as a percentage of the negotiated price, minus a trade-in. That is how many states write their sales-tax statutes. The District does not. Under D.C. Official Code § 50-2201.03(j), a titled purchase pays a motor vehicle excise tax at DMV. It is not ordinary retail sales tax on the vehicle. It is not Georgia Title Ad Valorem Tax. It is not Maryland’s 6.5 percent titling excise, and it is not Virginia’s sales-price titling tax.

The statutory base is fair market value at the time the certificate of title is issued. The Director uses the then-current NADA Guide (Eastern Region). If NADA has no value for the vehicle, the bill of sale is used—18 DCMR § 401.16. Purchase price may be requested as information under § 50-2201.03(j)(2), but the Code does not say “price minus trade.” There is no statutory trade-in credit that reduces FMV, and manufacturer rebates are not written into § 50-2201.03(j) as a base reduction.

The rate is not a single statewide percentage either. Since the Motor Excise Tax Amendment Act of 2024, DMV publishes a grid that pairs unladen weight with city MPG rounded down to the nearest whole number—or a dedicated electric-vehicle column. That table took effect on 17 February 2025. Older prints that show 8.1 percent / 4.4 percent cells, or that still say electric vehicles pay zero excise, are stale.

Important: Do not apply Maryland 6.5%, Virginia titling or sales figures, or Georgia TAVT to a District title. A calculator that copies those engines is not computing DC law.

Leases sit on a different path. Rental and leased vehicles are generally excise-exempt if they are subject to the gross-receipts / sales-tax rules in §§ 47-2002(a)(4B) and 47-2002.02(2)(C). A purchase-loan calculator should leave lease tax out of the default path.

Official DC Fees You Can Rely On (2026)

Some costs are fixed by the Code or published on the DMV fee pages. A responsible DC auto loan calculator should use these as defaults—not averages from industry websites.

FeeAmountSource
Title / duplicate / retitle$30§ 50-2201.03(d); DMV title fees (post–30 Mar 2026)
Lien recordation (if financed)$20 per lienDMV title-fee page

Passenger Class II (3,500–4,999 lb)$175 / yearSame
Passenger Class III (5,000–5,999 lb)$300 / yearSame
Passenger Class IV (≥ 6,000 lb)$550 / year + $75 per 1,000 lb over 10,000Same
New BEV Class V (< 5,000 lb, first 2 years)$40 / year§ 50-1501.03 Class V
New ICE inspection sticker (MCO path)$10 / 4 yearsDMV inspection fees
Used personal inspection$35 / 2 yearsSame
100% electric personal inspectionExemptDMV inspection exemptions

Registration may be issued for up to two years under § 50-1501.03(i). The worked examples in this guide use one year at the Class I rate unless noted. A $12 tag transfer is a transfer fee, not the first-registration default.

Dealer processing or documentary fees have no statutory dollar cap located in the motor-vehicle finance title. A calculator should default that charge to $0 unless you type your dealer’s amount. Misrepresenting a dealer fee as a government charge is a consumer-protection issue for the Office of the Attorney General and the Consumer Protection Procedures Act—not an official calculator default.

DMV also notes a 2.5% card service fee (from 15 December 2025) on debit and credit transactions. That is a payment-method surcharge. It is not part of the loan-principal formula unless you choose to roll it.

Example 1: Brand-new gasoline sedan, Class I

Scenario: You title a new passenger car that weighs 3,200 pounds. You finance the purchase, so DMV records one lien. You take the manufacturer Certificate of Origin path for inspection.

Title certificate: $30.00 Lien recordation: $20.00 Class I registration (1 year): $70.00 New-vehicle inspection sticker: $10.00 ───────────────────────────────────── Government fees (before excise): $130.00

Excise is extra. It is not in this $130. Excise depends on FMV and the MPG cell, which we compute in the next section.

Example 2: New battery-electric car under 5,000 pounds

Scenario: Same $38,000 FMV illustration, but the vehicle is 100% electric and under 5,000 pounds in its first two registration years.

Title + one lien: $50.00 Class V registration (year 1): $40.00 Inspection (100% electric): $0.00 ───────────────────────────────────── Government fees (before excise): $90.00

Hybrids and plug-in hybrids do not get Class V. After the first two years, a qualifying BEV moves to Class I or Class II by weight. A BEV under 5,000 pounds may subtract 1,000 pounds for classing under § 50-1501.03(b)(1)(A).

How DC Excise Tax Is Calculated

Excise is fair market value times the table rate for the vehicle’s unladen weight and city MPG—or the electric-vehicle column. City MPG is rounded down to the nearest whole number. Do not use MPGe in the gasoline columns.

The DMV grid effective 17 February 2025 is:

Unladen weight≤20 MPG21–2526–3031–39≥40 MPGElectric
3,499 lb or less9.0%5.0%3.1%2.2%1.5%1.0%
3,500–4,999 lb10.0%6.0%4.1%3.2%2.5%2.0%
5,000 lb or more11.0%7.0%5.1%4.2%3.5%3.0%

Electric vehicles are no longer exempt. They use the EV column. A calculator that still shows $0 excise on a Tesla or other BEV is using a repealed rule.

Dealer and private-party purchases use the same statute. Both hit § 50-2201.03(j) unless an exemption applies. FMV still follows NADA or the bill of sale under 18 DCMR § 401.16. Cash down does not reduce excise. A trade-in allowance reduces what you borrow, but it does not cut the FMV used for tax.

Example 1: Class I car, 26–30 city MPG (the standard illustration)

Scenario: New DC title, non-EITC, gasoline passenger car at or under 3,499 pounds. City MPG rounded down lands in 26–30. FMV for illustration is $38,000—replace this with the NADA Eastern Region figure DMV will actually use.

Fair market value: $38,000 Table rate (Class I, 26–30 MPG): 3.1% ───────────────────────────────────── Excise = $38,000 × 0.031 = $1,178.00

That $1,178 does not change if you put $3,800 down or if the dealer gives you $5,000 on a trade. Down payment and trade change the loan. They do not change this tax under the Code.

Example 2: Same Class I car in a thirstier MPG cell

Scenario: Same $38,000 FMV and same weight, but city MPG rounded down is 21–25.

Table rate (Class I, 21–25 MPG): 5.0% Excise = $38,000 × 0.05 = $1,900.00 Difference vs 26–30 MPG cell: $1,900 − $1,178 = $722 more tax

Fuel economy is not a “nice to have” on a DC title. Moving one cell on the official grid can add hundreds of dollars to the amount you finance or the cash you bring to DMV.

The EITC lesser-of election

Individuals who claimed and received the District Earned Income Tax Credit for the closest return period may use the lesser of the MPG/EV schedule and the older statutory weight-class rates in § 50-2201.03(j)(1): Class I 6%, Class II 7%, Class III 8%. OTR confirmation is required—§ 50-2201.03(j)(1A)(G); 18 DCMR § 401.20. The default calculator path is the MPG/EV table unless you flag EITC.

Example 1: EITC helps a low-MPG Class I car

Scenario: Class I, 20 MPG or less. Table rate is 9.0%. You qualify for the EITC election. The statutory Class I floor is 6%.

MPG table rate: 9.0% EITC Class I rate: 6.0% Lesser of the two: 6.0% Excise on $38,000 = $38,000 × 0.06 = $2,280.00 Without EITC: $38,000 × 0.09 = $3,420.00

The election saves $1,140 in this cell. You still need OTR confirmation. Do not assume every buyer qualifies.

Example 2: EITC does not help a 26–30 MPG Class I car

Scenario: Same Class I car at 3.1%. The statutory Class I rate is 6%.

MPG table rate: 3.1% EITC Class I rate: 6.0% Lesser of the two: 3.1%

The MPG schedule is already lower. Checking the EITC box should not raise your tax. A calculator that always applies 6% / 7% / 8% is using the stale ORA-style print, not the February 2025 grid.

New Residents and Out-of-State Purchases

Section 50-2201.03(j)(3)(H) exempts certificates for motor vehicles and trailers registered or titled in another state or U.S. jurisdiction by a nonresident before that person established or maintained residency in the District. That is a full exemption for a qualifying bring-in. It is not Maryland’s “pay the rate difference” credit.

A current DC resident who buys a vehicle to title in the District pays the full FMV × table-rate path unless another (j)(3) exemption applies. Crossing into Maryland or Virginia to shop does not, by itself, erase District excise on a new DC title.

Example 1: Qualifying new-resident bring-in

Scenario: You moved to the District with a car already titled and registered in your name in another state before you became a DC resident.

Excise under § 50-2201.03(j)(3)(H): $0.00 Title (if a DC title is issued): $30.00 Registration (Class I example): $70.00 Inspection (used personal, if due): $35.00

You still pay title, registration, and inspection as they apply. You do not run Maryland-style credit math.

Example 2: DC resident buys out of state and titles here

Scenario: You already live in the District. You buy a $38,000 Class I, 26–30 MPG car from a Virginia dealer and title it at DC DMV.

FMV (illustration): $38,000 Excise at 3.1%: $1,178.00 Title + one lien: $50.00 Class I tag + sticker: $80.00

The Virginia lot’s local tax rules do not replace District excise on a DC title. Confirm any credit for tax legally paid elsewhere with DMV; do not invent a Maryland-style difference credit.

Interest Rates: What the Government Actually Publishes

The District does not publish an official citywide auto loan APR. The closest government benchmark is the Federal Reserve’s G.19 Consumer Credit release, which reports Regulation Z APRs for new-car loans.

As of the 7 August 2026 release (Q2 2026 / June data):

SeriesRatePeriod
Commercial bank 60-month new car7.14%Q2 2026
Commercial bank 72-month new car6.97%Q2 2026
Finance company new car (amount-weighted)6.1%Q1 2026

These are not your guaranteed rate. Bank figures are unweighted averages of each bank’s most common quoted rate in a specific week—not weighted by how many loans closed, and not District-specific.

Important: G.19 does not publish a used-car APR. There is no official government “used car rate” to prefill. Enter your lender’s quote. A calculator may show 7.14% only as an illustration labeled as the new-car bank average—not as a promise of your rate.

Do not assume a longer term is cheaper just because the 72-month bank average (6.97%) prints below the 60-month average (7.14%). The Fed explains that mix is which rate each bank quotes most often, not a mathematical term discount. Sixty months is a reasonable default only because G.19 publishes a 60-month series. Eighty-four months is not an official government default.

How Loan Payments Are Calculated

Once you know amount financed, the monthly payment uses standard amortization. Treat the entered rate as a nominal annual rate, compounded monthly. Monthly rate is the annual rate divided by 12.

For amount financed P over n months at monthly rate i:

Payment = P × [ i × (1 + i)n ] ÷ [ (1 + i)n − 1 ]

If the rate is zero, payment is simply P divided by n. Round the payment to the nearest cent (half-up). The last payment clears whatever residual remains. Totals come from that schedule. This is an estimate, not a Truth in Lending (Regulation Z) solution and not a lender offer.

Amount financed is approximately:

  • Vehicle price (plus any dealer processing fee you entered)
  • Minus down payment, trade-in allowance, and rebate (rebate reduces the loan, not DC FMV excise)
  • Plus trade payoff if you still owe money on the trade
  • Plus excise, title, lien, tag, and inspection if you roll those government charges
  • Plus financed GAP or a service contract

Cash due at signing is approximately your down payment plus any excise and fees you pay up front instead of financing.

Rolling excise into the loan does not change the tax owed. It changes when you pay it and how much interest you pay over time. Trade-in reduces loan principal like any allowance. Under the Code, it does not reduce FMV excise.

Example 1: Roll excise and DMV fees into the loan (Example A)

Scenario: New DC title, Class I, 26–30 city MPG, FMV and price $38,000, down $3,800, no trade or rebate, title $30, one lien $20, one-year Class I tag $70, new-vehicle sticker $10. APR 7.14%, 60 months. Tax and fees financed.

Excise: $38,000 × 0.031 = $1,178.00 Title + lien + tag + sticker = $130.00 ───────────────────────────────────── Amount financed: $38,000 − $3,800 + $1,178 + $130 = $35,508.00 Monthly payment (7.14% / 60 mo): $705.45 Cash due at signing: $3,800.00 Total of payments: $42,326.89 Total interest: $6,818.89

This is the official worked Example A from the District fact brief. Your NADA FMV may differ from $38,000. Replace it before you treat the payment as your number.

Example 2: Pay excise and fees in cash (Example B)

Scenario: Same $38,000 vehicle and $3,800 down—but you pay excise and DMV fees at signing instead of financing them.

Amount financed: $38,000 − $3,800 = $34,200.00 Cash at signing: Down payment: $3,800.00 Excise: $1,178.00 Title + fees: $130.00 ───────────────────────────── Total cash due: $5,108.00 Monthly payment: $679.46 Total of payments: $40,767.75 Total interest: $6,567.75

Rolling costs about $251 extra interest over 60 months and saves $1,308 cash on day one compared with paying government charges at signing.

Important: Any online estimate is not a Truth in Lending disclosure and is not a lender offer. Your contract controls the final payment, fees, and APR.

How the DC Auto Loan Calculator Works

A calculator that follows the official District brief does the work in a fixed order. You do not need to memorize the Code. You do need to enter the facts DMV will use.

  1. Purchase details. Enter purchase channel, price, dealer processing fee (default $0), down payment, trade-in, trade payoff, and rebate. Trade and rebate change the loan. They do not change FMV excise.
  2. Fair market value. Enter the NADA Eastern Region value if you have it. If you leave FMV blank or at $0, a practical estimator may use purchase price as a stand-in—you should replace that with the guide DMV will apply.
  3. Weight class and city MPG (or EV). These two dropdowns pick the cell on the 17 February 2025 table. City MPG is rounded down. Electric vehicles use the EV column, not 0%.
  4. Registration path. New gasoline or diesel cars use Class I–IV by weight plus the $10 new-vehicle sticker. A new 100% electric passenger under 5,000 pounds can use Class V at $40 for the first two years and skip inspection. Used cars budget the $35 / two-year inspection separately when it applies.
  5. Optional flags. Lien recordation adds $20. The EITC box applies the lesser of the MPG table and 6% / 7% / 8% by weight. Roll-tax and roll-fees decide whether government charges sit in the loan or in cash due.
  6. Financing. APR defaults to 7.14% as the G.19 60-month new-car bank average. Term defaults to 60 months. Change both to match your lender. There is no official used-car APR and no credit-score table.
  7. Results. You should see FMV, the selected excise rate, excise dollars, title and registration, amount financed, estimated monthly payment, cash due, total of payments, and total interest.

D.C. Official Code § 50-601 and following, and 16 DCMR Chapter 3, govern retail installment financing of motor vehicles. Principal may include identified governmental charges—§ 50-601(8). Dealers and holders generally may not exact extra value for services beyond that chapter, and waiver clauses of the chapter are void—16 DCMR § 336. There is no statutory three-day cooling-off period located in the motor-vehicle finance title for a completed dealership purchase. Do not invent one.

Example 1: Same Class I car at 21–25 MPG, tax and fees rolled

Scenario: Official Example C. Price and FMV $38,000, down $3,800, Class I, 5.0% cell. Fees still $130.

Excise: $38,000 × 0.05 = $1,900.00 Rolled amount financed: $34,200 + $1,900 + $130 = $36,230.00 Monthly payment at 7.14% / 60: $719.79

Compared with the 3.1% cell in Example A ($705.45), the thirstier MPG band adds about $14.34 per month when everything is financed.

Example 2: Trade-in changes the loan, not the tax (Example D)

Scenario: Price and FMV $38,000, trade allowance $5,000, down $0, Class I, 26–30 MPG.

Loan principal before government charges: $38,000 − $5,000 = $33,000.00 Excise remains: $38,000 × 0.031 = $1,178.00

Maryland-style “price minus trade” tax math is wrong in the District. If a worksheet shows excise on $33,000, ask why. G.19 has no used-car APR; enter the rate your lender actually quoted.

Complete End-to-End Examples

The two deals below use only official 2026 defaults from the District fact brief. They are planning numbers, not a contract.

Example 1: New ICE sedan, everything rolled (full Example A)

Scenario: You buy a new 3,200-pound gasoline car in the District. City MPG rounded down is 28. You put 10% down. You finance tax, title, one lien, one year of Class I tags, and the new-vehicle sticker at the G.19 60-month bank average.

Purchase price / illustrated FMV: $38,000.00 Cash down: − $3,800.00 Excise (3.1%): + $1,178.00 Title: + $30.00 Lien: + $20.00 Class I registration: + $70.00 Inspection sticker: + $10.00 ───────────────────────────────────────────── Amount financed: $35,508.00 Monthly payment: $705.45 Cash due: $3,800.00 Total of payments: $42,326.89 Total interest: $6,818.89

If DMV’s NADA value is higher or lower than $38,000, every tax and payment line moves. The $38,000 figure is an illustration, not an official average price—the government does not publish one.

Example 2: New BEV, Class V, excise at 1.0%

Scenario: Same $38,000 FMV, Class I weight, 100% electric. First registration year uses Class V. Inspection is exempt. You roll tax and fees. Down $3,800. APR 7.14%, 60 months.

Excise (EV column, ≤ 3,499 lb): $38,000 × 0.01 = $380.00 Title + lien: $50.00 Class V registration: $40.00 Inspection: $0.00 ───────────────────────────────────────────── Amount financed: $38,000 − $3,800 + $380 + $90 = $34,670.00

Do not leave an EV at 0% excise. Do not give Class V or the inspection exemption to a hybrid. After two years, budget Class I or Class II registration instead of $40.

Common Questions

Does a trade-in reduce DC excise tax?

No. Trade-in reduces the amount you finance if the dealer gives you an allowance. Section 50-2201.03(j) taxes FMV of the vehicle being titled. There is no statutory trade-in subtraction in that section. Manufacturer rebates are also not written in as a base reduction.

Should I use the sticker price or NADA?

DMV uses the NADA Guide (Eastern Region). The bill of sale is used only if NADA has no value—18 DCMR § 401.16. A calculator may let you type FMV and fall back to purchase price if you leave FMV blank. Confirm the guide value before you treat the estimate as final.

Are electric vehicles still exempt from excise?

No. The February 2025 DMV table has an EV column (1.0% / 2.0% / 3.0% by weight). EVs can still qualify for Class V registration and the 100% electric inspection exemption. Those are registration and inspection rules, not a $0 excise holiday.

I just moved here. Do I pay the full excise?

If the vehicle was titled or registered in your name in another jurisdiction before you became a DC resident, § 50-2201.03(j)(3)(H) is a full exemption. If you already live here and buy a car to title in the District, you are on the ordinary FMV × table path unless another exemption applies. This is not Maryland’s rate-difference credit.

Is there an official used-car APR or a credit-score table?

No. G.19 does not publish a used-car series. No District or federal table in this brief assigns APR by FICO. Enter the rate your credit union or bank quoted. Industry survey tiers are not official defaults.

Is there a three-day right to cancel at the dealership?

No statutory cooling-off period for a completed dealership purchase was located in the motor-vehicle finance title. Do not plan on a three-day cancel right unless some other law clearly applies to your facts.

What about lemon law or a doc-fee cap?

There is no lemon-law surcharge as a DMV line item on the purchase. There is no statutory dollar cap located for dealer processing fees. Default doc fee is $0. Do not copy another state’s cap into a DC worksheet.

Data Sources and Accuracy

This guide and a compliant DC auto loan calculator rely on:

  • D.C. Official Code §§ 50-2201.03, 50-1501.03, and 50-601 et seq.
  • 18 DCMR §§ 401.16 and 401.19–401.20, using DMV’s published 17 February 2025 rate grid when older DCMR cells still show pre-amendment percentages
  • 16 DCMR Chapter 3, including § 336
  • DC DMV title, registration, inspection, exemption, estimator, and 30 March 2026 fee-change pages (accessed 1 September 2026)
  • Federal Reserve G.19 (7 August 2026 release) for the labeled 60-month new-car bank average

Rates and fees change when the Council acts or when DMV updates a schedule. Confirm final amounts with your lender and DC DMV before you sign. Official estimators to link—not scrape—include the Vehicle Registration and Title Fee Estimator and DMV’s online excise tool.

Conclusion

District car financing is built on three layers: excise tax (FMV × the weight-and-MPG or EV cell, with no trade-in cut), official DMV title and registration fees (fixed dollars from the Code and the 30 March 2026 fee pages), and loan math (amount financed, your APR, and term—with a government benchmark only for the new-car bank average, not your personal rate).

The biggest mistakes shoppers make are treating DC like a price-minus-trade sales-tax state, copying Maryland 6.5% or Virginia figures, using a pre–February 2025 MPG table, leaving electric vehicles at $0 excise, or trusting credit-tier APR charts that no government agency publishes. Work through your deal with the real NADA FMV, the correct weight and city-MPG cell, the roll-in choice you can actually cash-flow, and the rate your lender quoted—then compare the result with DMV’s own estimator when you are ready to title the vehicle.
