Best No-Annual-Fee Citi Cards in 2026

Quick answer

Citi's no-annual-fee rewards lineup lost two of its three cards in 2026, so the honest answer is short: the one you can still apply for is the Double Cash — 2% on everything, 1% when you buy and 1% when you pay. The Custom Cash closed to new applicants on May 28, 2026, and the Citi Rewards+ was folded into the Strata family; both keep their sections below because their terms still govern existing accounts and because "can I still get one?" is what brings most people here. For balance transfers rather than rewards, the Citi Simplicity and Diamond Preferred still carry the longest 0% intro APR periods of any no-AF Citi card.

TL;DR: Citi's no-annual-fee card lineup in 2026 includes: Citi Double Cash (2% cash back — 1% when you buy, 1% when you pay; earns ThankYou Points at 2x when enrolled); Citi Custom Cash — closed to new applicants since May 28, 2026 (5% cash back on top spend category up to $500/month, 1% after; categories include restaurants, grocery stores, gas stations, select travel, select transit, select streaming services, drugstores, home improvement stores, fitness clubs, live entertainment); Citi Rewards+ — closed, folded into Citi Strata (rounds all purchases up to the nearest 10 ThankYou Points, earns 2x at supermarkets and gas up to $6,000/year, 10% points rebate on first 100,000 TY points redeemed per year); Citi Simplicity (no late fees, no penalty APR, 0% intro APR on balance transfers for 21 months); and the Citi AAdvantage MileUp (2x AAdvantage miles at grocery stores and on American Airlines purchases, no annual fee).

At a glance: The best no-AF Citi cards compared

Citi Double Cash: best flat-rate card

The Double Cash is the gold standard of flat-rate cash back cards — see the full Citi Double Cash review for all the details. It earns 2% cash back on every purchase — 1% when you make the purchase, and another 1% when you pay the bill. There are no categories to track, no spending caps, no quarterly activations.

Key details:

• Annual fee: $0
• Earn rate: 2% on everything (1% + 1%)
• Foreign transaction fee: 3%
• Credit score needed: 670+ (700+ recommended)
• Balance transfer offer: 0% intro APR for 18 months on balance transfers (3% fee)
• ThankYou Points: If you enroll, cash back converts to ThankYou Points at 2x rate — giving you 2 TY points per dollar. These can be transferred to airline partners only if you also hold a premium TY card like the Strata Premier.

The Double Cash math: On $20,000 annual spend, you earn $400 in cash back. That beats most competing 2% cards (like the PayPal Cashback Mastercard or Fidelity Rewards) because the Double Cash also has a balance transfer option and is linkable to the ThankYou ecosystem.

Who it's for: Anyone who wants maximum simplicity. If you don't want to think about which card to use at which store, the Double Cash is the answer. It's also an excellent companion to a premium TY card for spending that doesn't fall into 3x or 5x categories.

Who it's NOT for: International travelers (3% FTF hurts), people who spend heavily in one category where a 5% card would win, or people who carry a balance (the ongoing APR after the intro period is high).

Citi Custom Cash: closed to new applicants

Closed to new applicants. Citi stopped accepting applications for the Custom Cash on May 28, 2026, and its product page has read "Not Available" since (citi.com, read 2026-08-25). This section stays because it still describes the terms governing existing accounts, and because "can I still get one?" is what brings most people here — it is not a recommendation.

The Custom Cash is a sleeper hit — read the Citi Custom Cash review for the full breakdown. It automatically earns 5% cash back on your top eligible spend category each billing cycle, up to $500 in spend (= $25 cash back per month = $300/year). After $500, you earn 1%. No activation needed — Citi tracks your spending automatically.

Eligible 5% categories:

• Restaurants
• Grocery stores
• Gas stations
• Select travel
• Select transit
• Select streaming services
• Drugstores
• Home improvement stores
• Fitness clubs
• Live entertainment

Key details:

• Annual fee: $0
• Top earn: 5% on the top category up to $500/month
• All other spending: 1%
• Foreign transaction fee: 3%
• Welcome bonus: $200 cash back after spending $1,500 in the first 6 months
• Credit score needed: 670+

The Custom Cash math: If your top category is restaurants and you spend exactly $500/month there, you earn $300/year in cash back from that category alone — equivalent to a 5% return. That beats every other no-annual-fee card on the market for single-category maximizers.

ThankYou Points note: If you have the Strata Premier and enroll the Custom Cash in ThankYou Rewards, your Custom Cash earnings convert to TY Points — giving you 5 TY Points per dollar on your top category (up to $500/month). At 1.5–2.0 cents per TY point via airline transfers, that's a 7.5–10% effective return on your top category. This is one of the highest return rates on any no-annual-fee card in the US market.

Citi Rewards+: closed to new applicants

Closed to new applicants. Citi folded the Rewards+ into the Strata family: its official URL redirects to the Citi Strata card, Rewards+ is gone from Citi's view-all catalog and its terms PDF with it, and no application path exists anywhere on citi.com (checked 2026-08-25). The rounding mechanic below applies to existing accounts only.

The Citi Rewards+ has a feature no other card offers: it rounds every purchase up to the nearest 10 ThankYou Points. See the Citi Rewards+ review for how the rounding math plays out across different spending patterns. Buy a $1.50 cup of coffee? You earn 10 points, not 1.5. Buy a $2 pack of gum? 10 points. On small purchases, this dramatically inflates your earn rate.

Key details:

• Annual fee: $0
• Earn rate: 2x at supermarkets and gas stations (up to $6,000/year), 1x on everything else — but every purchase rounds up to nearest 10 points
• Foreign transaction fee: 3%
• 10% points rebate: On the first 100,000 TY points redeemed per year (worth up to 10,000 bonus points/year)
• Welcome bonus: 20,000 TY points after $1,500 spend in 3 months
• Credit score needed: 670+

The Rewards+ math on small purchases: At 10 points minimum per transaction, if you make 200 small purchases of $2–$5 each per month, you earn at least 2,000 points/month from rounding alone — even if those purchases would have earned 200–1,000 points at the standard 1x rate. The rounding bonus effectively functions as a 2–5x multiplier on small transactions.

Best use case: Vending machines, parking meters, coffee shops, small convenience store purchases, transit fares — any purchase under $10 where rounding to 10 points provides an outsized return.

10% rebate strategy: If you use the Rewards+ alongside the Strata Premier (which can transfer points to airlines), you can pool your TY points and redeem them through the TY portal. The Rewards+ then returns 10% of those points, up to 10,000 bonus points per year — worth $100–$200 depending on how you use them.

Citi Simplicity: best balance transfer card

The Citi Simplicity is not a rewards card — it's a tool. Its value is in the longest 0% introductory APR on balance transfers on any no-annual-fee Citi card: 21 months. It also uniquely charges no late fees and no penalty APR, making it forgiving if you miss a payment.

Key details:

• Annual fee: $0
• 0% intro APR: 21 months on balance transfers (then variable APR)
• Balance transfer fee: 5% ($5 minimum)
• 0% intro APR on purchases: 12 months
• No late fee: True
• No penalty APR: True
• Rewards: None (1% cash back is minimal/irrelevant)

The Simplicity math: Transferring $10,000 in high-interest debt at a 5% transfer fee costs $500 upfront. But at a 20% APR on the original card, 21 months of interest would have cost ~$3,500. The Simplicity saves ~$3,000 on $10,000 in transferred debt over the intro period. For people carrying credit card debt, this is the most valuable Citi card available — regardless of rewards.

Warning: After 21 months, the APR reverts to a high variable rate. You must pay off the transferred balance before the intro period ends or you'll face interest charges on the remaining balance.

Citi AAdvantage MileUp: best no-AF airline card

The Citi AAdvantage MileUp is the only no-annual-fee American Airlines co-branded card, earning 2x AAdvantage miles at grocery stores and on American Airlines purchases, and 1x everywhere else.

Key details:

• Annual fee: $0
• Earn at grocery stores: 2x AAdvantage miles
• Earn on American Airlines purchases: 2x AAdvantage miles
• Earn everywhere else: 1x
• Welcome bonus: 10,000 AAdvantage miles + $50 statement credit after $500 spend in 3 months
• Foreign transaction fee: 3%
• No first checked bag free (that's on the Platinum Select)
• No preferred boarding

Who it's for: Infrequent AA flyers who want to accumulate AAdvantage miles for free, or people who want a low-commitment way to keep their AAdvantage account active with mile earning. The grocery 2x is legitimately useful for everyday spend.

The MileUp vs. Platinum Select decision: The AA Platinum Select costs $99/year but includes a free first checked bag ($35 one-way, $70 round-trip for you plus up to 4 companions) and preferred boarding. If you take 2+ roundtrips on AA per year and check a bag, the Platinum Select pays for itself immediately.

Choosing the right no-AF Citi card

Can you hold multiple no-AF Citi cards?

Yes — Citi's application rules (the 8/65 rule: 1 card per 8 days, 2 per 65 days) still allow it. But the no-annual-fee stack this guide used to describe cannot be built from scratch any more: it rested on two Custom Cash cards and a Rewards+, and all three are closed to new applicants.

What you can still open today: the Double Cash on its own, or the Double Cash paired with the Strata Premier ($95) — which is the pairing that makes Double Cash earnings transferable inside the ThankYou ecosystem. That is a two-card setup with a fee attached, not the free trifecta.

If you already hold the closed cards, nothing changes: they keep earning and they keep pooling points, and the Citi trifecta strategy still describes what to do with them.
