Tesla Referral Code for the USA (2026)

What a referral code is worth in the US today

Federal & state incentives you can stack (verify current)

A referral benefit is separate from any government EV incentive. The FSD trial is applied by Tesla at checkout; a federal or state EV credit or rebate is claimed under its own program with its own eligibility (income caps, price caps, assembly and battery-sourcing rules, and point-of-sale vs tax-time mechanics). Because these rules shift and depend on your state and the specific vehicle, we do not print a dollar figure here — confirm the current terms for your state and model before counting on them. What is safe to say: using a referral does not disqualify you from a government incentive, and vice versa.

The federal layer, as it actually stands

The caution above was written when there was a federal purchase credit to be cautious about. There is not one now, and saying so plainly is more useful than a hedge, because the hedge reads as though the credit is still there waiting to be checked.

All three expiries came from the same legislation, on hard dates rather than phase-downs. Anyone who entered a binding purchase contract and made a payment before 30 September 2025 could still claim §30D when the vehicle was placed in service; for an order placed today that route is long closed.

The one federal item that is left, and its cliff

The auto-loan interest deduction is the remaining federal line, and it is easy to over-read because of its headline number. Three things determine whether it reaches you at all:

• Income. It begins phasing out above $100,000 modified AGI for a single filer or $200,000 filing jointly, losing $200 of deduction per $1,000 above the threshold — so it is gone entirely at $150,000 or $250,000. A $50,000 band takes it from full to nothing.
• The car. It must be a new passenger vehicle assembled in the United States.
• The arithmetic. The $10,000 cap is a ceiling on interest paid, not a payout. Reaching it means paying $10,000 of interest in one year, and the benefit is then that figure times your marginal rate — not $10,000.

Which leaves state, municipal and utility programs as the largest remaining layer for most buyers, and those genuinely do vary by address — so we still decline to print a figure for them. That caution now applies to the part where it belongs, rather than standing in for a federal credit that no longer exists.

None of this touches the referral. Using one does not affect eligibility for anything above, and nothing above affects the referral. It remains the smallest item on the page and the only one with no income test, no address test and no assembly test.

How to apply at checkout

1. 1

   Open the referral link first

   Before you configure anything, open a valid referral link (a ts.la/… address wraps an owner's code). This tags your session so the benefit is recognised.

2. 2

   Configure and place your order

   Build your Model 3, Model Y or eligible Cybertruck and go to the order screen. The 3-month FSD (Supervised) benefit shows in the order summary before payment — there is no coupon box to type into.

3. 3

   Confirm it applied, then pay

   Check the order summary lists the referral benefit before you submit. Tesla does not add a referral after an order is placed, so verify it is there first.
