Key takeaways
- Welcome bonuses apply only to the primary cardholder; the secondary user's spending does count toward minimum thresholds, making them valuable for reaching bonuses faster.
- Spending by additional cardholders earns points at the same rates and categories as the primary cardholder, accumulating in a single account shared by both.
- Annual fees for secondary users range from free (Nubank) to 50–75% of the primary card's fee (Itaú, Bradesco) or up to 100% on premium tiers; calculate fee payback using annual spending and redemption value.
- Secondary cardholders cannot independently redeem points on most programs—the primary account holder retains full control, so confirm this before adding family members.
Adding a secondary cardholder to your credit card account is one of the fastest ways to increase household point accumulation—but the rules around how they earn, what bonuses apply, and what you’ll pay in annual fees vary significantly across Brazilian banks and card tiers. Understanding these mechanics before adding a spouse, partner, or adult family member can mean the difference between a smart rewards strategy and an expensive mistake.
What Is an Additional Cardholder and How Does It Work?
An additional cardholder—also called an authorized user—is a secondary person granted the right to make purchases on your credit card account. Unlike a co-applicant, they do not share liability for the debt; the primary cardholder remains the account holder and responsible for payment. All spending by the additional user posts to the primary account, which is why their purchases count toward your reward accumulation and annual spending thresholds.
This structure is important because it means you don’t need separate card applications or credit checks. Most Brazilian banks allow you to add secondary cardholders through their mobile app or website in minutes. Nubank, Itaú, Bradesco, and Santander all support this feature, though the mechanics and fees differ.
Welcome Bonuses: Primary Cardholder Only
The first rule: welcome bonuses almost never apply to additional cardholders. If your primary card offers 50,000 points for spending R$5,000 in the first 60 days, only you qualify for that bonus. The secondary user’s purchases count toward the spending requirement, but the bonus is credited to your account once.
This is a critical distinction. Some cardholders add a spouse or family member expecting the household to earn two separate welcome bonuses—they don’t. Plan your spending accordingly: if both of you are heavy spenders, consider timing the additional card’s arrival *after* you’ve cleared the primary cardholder’s minimum spending, so the secondary user’s transactions in months 2 and 3 don’t inflate the spending total unnecessarily.

Ongoing Rewards Accumulation
Standard Earning Rates
All spending by the additional cardholder earns at the same rate as the primary cardholder. If your card offers 1.5 points per real spent on dining, that rate applies to both you and your secondary user. Points post to a single account—the primary cardholder’s—not divided or issued separately. This is where adding a second user becomes powerful: household spending of R$10,000 across two cardholders earns the same 15,000 points as if the primary cardholder spent it alone.
Category-Specific Bonuses
Premium cards from Itaú, Bradesco, and Santander often feature elevated earning rates in specific categories: 3x points on flights, 2.5x on hotels, 2x on restaurants. These multipliers apply to the secondary cardholder’s transactions in those categories as well. If you and your spouse both travel frequently, adding them as an authorized user effectively doubles your category bonus earning potential from shared purchases like hotel reservations or flight bookings placed under one card account.
Annual Spending Thresholds
Many premium cards raise their earning rates or unlock benefits once you cross an annual spending threshold—often R$15,000 or R$30,000 in real Brazilian banks. The secondary cardholder’s spending counts toward this total, making it realistic to reach these tiers faster. If you spend R$12,000 annually and add a spouse who spends R$5,000, you now hit R$17,000 and potentially unlock an elevated earn rate or status upgrade retroactively.
Annual Fees and Costs
This is where secondary cardholders diverge most significantly across programs.
Free additional cards: Nubank and several entry-level credit cards charge zero for secondary cardholders, regardless of how many you add. If cost is your primary concern, these cards are unbeatable for household earning strategies.
Discounted additional cards: Itaú, Bradesco, and Santander typically charge 50–75% of the primary card’s annual fee for each secondary cardholder. If the primary card costs R$500 annually, expect to pay R$150–R$250 per additional user. Some banks apply these fees annually on the cardholder’s birthday; others during the anniversary month of the primary account.
Premium and black cards: Ultra-premium tiers may charge 80–100% of the primary fee for each secondary user, sometimes up to R$400–R$600 per person, depending on the bank and card tier. However, these cards often include perks—concierge services, travel insurance, lounge access—that extend to secondary cardholders, partially offsetting the cost.
The key math: if adding a secondary cardholder costs R$200 annually but their spending earns an extra 5,000 points per year, and your program values points at R$0.02–R$0.03 per point (100–150 reais in value), you’re breaking even or coming out ahead. This calculation varies per family and card, which is why checking the fee before committing is essential.
Program-Specific Rules and Variations
Nubank
Nubank’s standard card offers free unlimited additional cardholders, and all spending counts toward a single points pool. There is no welcome bonus cap or secondary-user restriction. This makes Nubank the most flexible entry point for couples or families building household rewards.
Itaú and Bradesco
Both charge discounted annual fees for secondary cards (typically 50–70% of primary). Spending by additional users counts fully toward category bonuses and annual thresholds. Some Itaú black cards allow additional users to access certain benefits independently—lounge access, for example—though points still accumulate to one account.
Santander
Santander allows free secondary cards on some tiers and charged tiers on others, depending on whether you’re in their standard or premium program. Always check your specific card tier; rules differ significantly within the same bank across product lines.
Strategies to Maximize Household Earnings
Combine spending patterns: Add a secondary user whose spending pattern complements yours. If you spend heavily on flights and hotels (3x multiplier) and your spouse shops groceries and pharmacies (standard rate), their spending still earns points and helps you reach annual thresholds faster without cannibalizing your high-multiplier categories.
Timing the addition: Add a secondary cardholder *after* you’ve satisfied the primary card’s minimum spending requirement for the welcome bonus. This prevents their early spending from inflating the threshold unnecessarily or disqualifying you from a bonus due to spending ceilings (some promotions cap at R$5,000–R$10,000).
Fee arbitrage with premium tiers: If your secondary cardholder will regularly use business travel benefits (lounge access, travel insurance, concierge services), a premium card’s secondary fee pays for itself. Calculate the independent value of perks—lounge access alone is worth R$50–R$150 per trip for frequent travelers.
Multiple cards for different categories: Some households maintain one travel-focused card and one cash-back or dining card. The secondary user can concentrate on whichever card optimizes for their personal spending, multiplying category bonuses across the household.
Common Mistakes and Tax Considerations
One frequent error: assuming the secondary cardholder can redeemed points themselves. Most programs require the primary cardholder to initiate all redemptions, even for points earned by secondary user spending. Verify this with your bank before adding a spouse or adult family member who expects autonomy.
Another: ignoring the cardholder agreement. Some banks restrict secondary cardholders from accessing certain benefits—premium lounges, concierge services, or specific transfer partners—even if the primary card includes them. Read the fine print.
From a tax perspective, points earned on credit card spending are not considered taxable income under current Brazilian law. Redemptions (flights, hotels, cash back) also do not trigger tax events for personal use. This remains true regardless of whether points were earned by primary or secondary cardholders, since points are the property of the account holder (the primary cardholder).
When Adding a Secondary User Makes Sense
The decision is simple: add a secondary cardholder if their annual spending (multiplied by the earning rate) exceeds the annual fee by a meaningful margin. For families spending R$50,000+ combined annually on a 1.5x standard earning rate card, adding a spouse with no fee (Nubank) is an obvious win. For couples spending R$20,000 total where a secondary card costs R$150 per year, the math depends on your redemption value—but the risk is low.
Less compelling: adding a secondary user to a premium card with a R$400 annual fee for secondary users unless they will actively use premium benefits like concierge, travel insurance, or lounge access. In that case, measure the fee against the independent cost of those services.
Frequently Asked Questions
Does an additional cardholder get their own welcome bonus?
No. Welcome bonuses apply only to the primary cardholder. However, spending by the additional user counts toward the primary cardholder's minimum spending requirement, allowing you to earn the single welcome bonus faster.
Do I have to pay an annual fee for each additional cardholder?
It depends on the card and bank. Nubank charges no annual fees for secondary cardholders. Itaú, Bradesco, and Santander typically charge 50–75% of the primary card's annual fee per additional user. Premium and black cards may charge higher percentages. Check your specific card's terms.
Can my spouse redeem points they earned with their secondary card?
No. Points from all cardholders accumulate to the primary account, and only the primary cardholder can redeem them. Secondary users cannot initiate redemptions independently on most Brazilian programs.
