Sign-up bonuses — also called welcome offers or SUBs — are the most efficient way to accumulate large quantities of rewards in a short period. A single well-timed application can earn hundreds of dollars in travel value or cash back. But the mechanics, timing, and tax implications are worth understanding before pursuing a bonus aggressively.
How Sign-Up Bonuses Work
A sign-up bonus is a one-time reward for opening a new credit card account and meeting a minimum spending requirement within a specified period — typically 3 months. The bonus is credited to your account after the spending threshold is met and the qualifying period ends.
Bonus structures vary: some require a single spending threshold (spend $4,000, earn 60,000 points), while others use tiered structures (earn 40,000 points after $2,000 spend, plus 20,000 more after $6,000 spend). Read the offer terms carefully to understand exactly what's required.
Meeting Minimum Spend Naturally
The most important rule for sign-up bonuses: meet the minimum spend requirement with purchases you would have made anyway. Spending money you wouldn't otherwise spend to earn a bonus is almost never mathematically worthwhile.
Strategies for meeting minimum spend naturally:
Time applications with large expenses: A home renovation, a vacation, a wedding, or a major appliance purchase can easily meet a $3,000–$5,000 minimum spend requirement.
Prepay regular expenses: Some service providers allow prepayment — insurance premiums, subscriptions, or utility bills.
Use the card for all normal spending: Redirect all existing spending to the new card during the qualifying period.
Tip
Time Applications Strategically
Apply for a new card 1–2 weeks before a large planned expense — a vacation, a home project, or a major purchase. This gives you the full 3-month window to meet the minimum spend, with the large expense providing an immediate head start.
Tax Implications of Rewards
The IRS generally treats credit card rewards as a rebate on purchases — not taxable income. This applies to cash back, points, and miles earned through spending.
However, bonuses earned without a spending requirement — such as a bonus for simply opening an account or referring a friend — may be treated as taxable income. Issuers are required to issue a 1099-MISC for referral bonuses and other non-spending rewards above $600.
For most cardholders, the tax implications of rewards are minimal. If you earn significant referral bonuses or non-spending rewards, consult a tax professional.
Note
Rewards Are Generally Not Taxable
Points and cash back earned through spending are generally treated as purchase rebates by the IRS — not taxable income. Bonuses earned without a spending requirement (referral bonuses, account opening bonuses with no spend) may be taxable. When in doubt, consult a tax professional.
Bonus Eligibility Rules
Most issuers have rules that limit how often you can earn a sign-up bonus on the same card. Common restrictions include: you must not have held the card in the past 24–48 months, you must not currently hold the card, or you must not have received a bonus on any card in the same product family within a specified period.
These rules vary significantly by issuer. Read the offer terms carefully before applying to ensure you're eligible for the bonus.
