Everyone loves to talk about the free flight they booked with points, or the $200 that landed in their account two months after opening a new card. What almost nobody talks about is the fine print that decides whether you actually get that bonus, or end up with a hard inquiry on your report and nothing to show for it.
Sign-up bonuses (sometimes called welcome offers) are genuinely one of the better deals in consumer credit right now. But “spend $4,000 in three months and get 60,000 points” is not the whole story, and issuers aren’t exactly rushing to explain the parts that work against you.
What a sign-up bonus actually is
A sign-up bonus is a one-time reward, usually cash back, points, or miles, that a card issuer gives you for opening a new account and hitting a spending target within a set window. It’s a customer-acquisition cost, plain and simple. Issuers know that once you’re carrying their card and it’s the one in your wallet by habit, you’ll probably keep using it long after the bonus posts, so they’re willing to pay up front to win that habit.
That’s useful context because it explains why the rules exist. Issuers want new spending from new customers, not people who open and close cards every few months to collect bonuses and never become a real customer. Most of the rules below are there to filter out exactly that behavior, even if they catch ordinary people in the process.
The minimum spend requirement, in plain terms
Minimum spend requirements vary a lot depending on the card’s value and target audience. On the lower end, a basic cash-back card might ask for a few hundred dollars in purchases. On the higher end, a premium travel card with a bonus worth $1,000+ in travel value might ask for several thousand dollars. The window to hit that number is almost always three months (90 days) from account opening, though a handful of cards use different windows, so always check your specific offer rather than assuming.
The math that actually matters here isn’t “can I hit the number,” it’s “will I spend this money anyway.” A bonus is only free if the spending behind it is spending you were going to do regardless, rent, groceries, gas, bills you can run through the card. If you’re buying things you wouldn’t normally buy just to clear the threshold, the bonus stops being free and starts being a discount on stuff you didn’t need.
The approval rules issuers don’t put on the application page
This is the part that trips people up the most, because none of it is printed clearly when you apply. Card issuers each run their own informal eligibility rules to stop people from bonus-hopping, and they’ve been pieced together over the years by people comparing notes on what got approved and what got denied.
Chase is the most well-known example. The pattern people have documented, often called the “5/24 rule,” is that Chase tends to deny applicants who’ve opened five or more credit cards (from any issuer, business cards included in some cases) in the past 24 months. It’s never been an official, published policy, but it’s consistent enough that most of the points-and-miles community treats it as real. If you’re close to that line, the practical move is to apply for the Chase card you want before applying anywhere else.
American Express generally limits welcome bonuses to once per lifetime per card. If you’ve already earned the bonus on a specific Amex card, even years ago, you typically won’t get it again on that same card, and some cards extend the restriction to a “family” of similar products.
Other issuers use time-based cooldowns instead of lifetime bans. Capital One and Citi, for instance, generally use something closer to a 48-month waiting period on some cards rather than a true once-ever rule, and Barclays tends to limit a given bonus to once per cardholder. None of these are guaranteed to stay the same, issuers adjust their terms fairly often, so the terms and conditions on your specific offer are the only source that’s actually binding.
The common thread: assume there’s an eligibility rule you can’t see until you’re denied, and don’t build a strategy around stacking several bonuses from the same issuer in a short window.
Where a hard inquiry fits into the decision
Applying for a new card generates a hard inquiry, and that’s a legitimate cost to weigh, just not a huge one. A single hard inquiry typically costs only a handful of points, and that effect tends to fade within a few months if the rest of your credit profile stays healthy. It’s a real factor if you’re about to apply for a mortgage or auto loan and want your file as clean as possible, but for most people chasing one bonus a year or so, it’s not a reason to avoid applying altogether.
Where it adds up is volume. Several applications in a short period, especially if a few get denied, is a different story than one well-timed application for a card you’d want anyway.
How people lose a bonus they already “earned”
Meeting the spending requirement isn’t always the end of the story. A few things can claw a bonus back even after you’ve cleared the threshold:
Returning purchases. If you return items that counted toward your minimum spend and the refund drops your total below the requirement, issuers can and do reverse the bonus. If you’d already redeemed it, your rewards balance can go negative until you earn enough to cover the gap.
Closing the account too soon. Many issuers reserve the right to claw back a bonus if you close the account within the first year, and some have gotten noticeably stricter about this in recent years as a way to discourage churning. Check your card’s specific terms before canceling anything you opened for a bonus.
Manufactured spending or terms violations. Things like buying money orders or gift cards purely to generate spend volume, with no real purchase behind them, violate most issuers’ terms. If they catch it, they can reverse the rewards before they ever post, and repeated violations can get the account closed outright.
Is chasing the bonus actually worth it?
Usually, yes, if you were going to open a new card anyway and can hit the spend with normal life expenses. The math gets worse fast in two specific situations: carrying a balance, and overspending to hit the threshold.
If you can’t pay off the spending you ran up by the statement due date, the interest charges on that balance can erase a big chunk of the bonus’s value, sometimes all of it, depending on how large the balance is and how long it sits there. A bonus worth a few hundred dollars doesn’t mean much if you’re paying ongoing interest to get there. Treat the bonus as a reason to use a card you were going to use anyway, not a reason to put more on plastic than you can pay off that month.
Frequently asked questions
Do sign-up bonuses count as taxable income?
This depends on the type of bonus and how it’s triggered, and the rules aren’t the same for every situation. It’s worth checking with a tax professional or the IRS’s own guidance if you want a definitive answer for your situation, rather than relying on a general rule of thumb.
Can I get the same card’s bonus twice?
Usually not, though it depends entirely on the issuer. Some use a once-per-lifetime rule, others use a waiting period of a few years, and a few will let you earn it again after enough time has passed. The specific offer terms for your card are the only reliable source, since these policies vary by issuer and change over time.
Will applying for a card hurt my credit score a lot?
Not usually. A single hard inquiry tends to cost a small number of points and the impact fades within a few months for most people. It matters more if you’re applying for several cards in a short window or if you have a thin credit file to begin with.
What happens if I don’t hit the minimum spend in time?
You generally just don’t get the bonus. The spending window doesn’t extend, and issuers aren’t typically willing to negotiate it, so it’s worth mapping out your planned spending against the deadline before you apply, especially if the minimum is a large one.
Is it smart to open a card just for the bonus if I don’t need a new card?
Be cautious here. A new account can briefly affect your average account age and adds a hard inquiry, and if you’re not going to use the card long-term, the bonus may not be worth the eligibility rules you trigger for future offers from that same issuer. It usually makes more sense when the card itself is also useful to you, not just the welcome offer.
Credit card terms, eligibility rules, and bonus structures change often and vary by issuer and by individual offer. The general patterns described here may not match your specific card or application, so always confirm current terms directly with the issuer before applying or making a decision based on a bonus.
