The blended retirement system army (BRS) is the military retirement plan that replaced the legacy "High-3" system for service members who joined after January 1, 2018.
According to the Department of Defense's Office of Financial Readiness, the BRS blends a reduced traditional pension with automatic and matching Thrift Savings Plan (TSP) contributions, creating a portable retirement benefit that follows you even if you leave before 20 years. The problem?
Many soldiers misunderstand how the matching works, when it starts, and what happens to their money if they separate early. This article breaks down the five most important facts about the Army BRS, how TSP matching actually functions, and the decisions you need to make during your opt-in window or at the two-year service mark.
What the Blended Retirement System Army Actually Is
The blended retirement system army combines three income sources: a defined benefit pension (monthly pay for life after 20+ years), defined contributions through the Thrift Savings Plan with government matching, and a Continuation Pay bonus at roughly 12 years of service.
The legacy High-3 system offered only the pension, which paid 50% of your base pay after 20 years — but nothing if you left at year 19.
Under BRS, the pension multiplier drops from 2.5% to 2.0% per year of service. So after 20 years, you receive 40% of your base pay instead of 50%. The trade-off is that the government now contributes 1% automatically to your TSP regardless of your own contributions, plus up to 4% in matching.
That means your total potential government contribution reaches 5% of base pay.
A common scenario: a specialist who separates after six years under the legacy system walked away with nothing. That same specialist under the blended retirement system army leaves with a TSP balance built from government contributions and their own savings — money that rolls into a civilian 401(k) or IRA.
How to apply this: Log into MyPay today and verify which retirement system your LES shows — the code "BRS" or "CHOICE" (meaning you have not yet made an election).
How TSP Matching Works Under the Army BRS
The Thrift Savings Plan is the centerpiece of the blended retirement system army, and the matching rules are where most soldiers make costly errors. The government contributes 1% automatically after 60 days of service, regardless of whether you contribute anything. Then, for the first 3% you contribute, the government matches dollar-for-dollar.
For the next 2%, the match drops to 50 cents on the dollar.
That means to receive the full 5% government contribution, you must contribute at least 5% of your base pay yourself. The DoD's Office of Financial Readiness states that "service members who contribute at least 5% of their base pay receive the maximum government match available under BRS."
One critical detail: matching starts after you complete two years of service. The automatic 1% begins at 60 days, but the additional 4% matching does not begin until your two-year anniversary. Soldiers who enroll but fail to increase their TSP contribution at the two-year mark leave free money on the table — often thousands of dollars annually.
How to apply this: Set your TSP contribution to at least 5% in MyPay now, and set a calendar reminder for your two-year service date to confirm the match has begun.
Opt-In Decisions and Deadlines for the Blended Retirement System Army
If you joined the Army before January 1, 2018, you had a choice: stay in the legacy High-3 system or opt into the blended retirement system army during the 2018 calendar year. That opt-in window closed on December 31, 2018. If you did not opt in, you remain under High-3.
For new accessions after January 1, 2018, enrollment in the BRS is automatic — there is no opt-out. However, new soldiers still face a critical decision: how much to contribute to TSP and which funds to select.
The default TSP contribution for new BRS members is 5% of base pay, which is a solid starting point, but the default fund allocation historically went to the G Fund (government securities), which offers lower long-term growth potential compared to the C, S, and I funds.
Consider the lifecycle funds, which automatically rebalance as you approach retirement. These are a practical option for soldiers who do not want to manage individual fund allocations.
How to apply this: If you are a new soldier, confirm your TSP contribution is set to at least 5% and review your fund allocation — do not leave money sitting in the default G Fund without understanding the trade-off.
Continuation Pay: The Often-Missed BRS Benefit
One of the least understood parts of the blended retirement system army is Continuation Pay. This is a one-time bonus paid to active component soldiers between their 8th and 12th year of service, provided they commit to four additional years.
The amount varies by service and year, but for the Army it has historically been a multiple of monthly base pay — often in the range of 2.5 to 13 times base pay depending on critical skills and needs of the Army.
The Army typically announces Continuation Pay rates annually. Soldiers who miss the application window or who are unaware of the benefit forfeit thousands of dollars. According to the Defense Finance and Accounting Service, Continuation Pay is taxable income and can be directed to your TSP if you choose, which is a strategy many financial counselors recommend.
A common scenario: a staff sergeant at year 11 hears about Continuation Pay from a friend, applies within the final eligibility window, and receives a lump sum that jump-starts a down payment on a home or a TSP catch-up contribution.
How to apply this: Mark your calendar for your 8-year service anniversary and check the Army's annual Continuation Pay message on the MyArmyBenefits website to see current rates and deadlines.
Blended Retirement System Army vs. Legacy High-3: Which Would Have Been Better?
The question every soldier asks is whether the blended retirement system army is better than the old High-3 system. The honest answer depends entirely on how long you plan to serve and how much you contribute to TSP.
The table below compares the two systems across key decision factors:
| Factor | Legacy High-3 | Blended Retirement System (BRS) | Action to Take |
|---|---|---|---|
| 20-year pension | 50% of base pay | 40% of base pay | Know your multiplier |
| Government TSP match | None | Up to 5% of base pay | Contribute at least 5% |
| Benefit if leaving before 20 years | Nothing | TSP balance + 1% automatic | Fund your TSP from day one |
| Continuation Pay | Not available | Yes, at 8-12 years | Apply during eligibility window |
| Portability | No | Yes, TSP rolls over | Plan for civilian transition |
The DoD's own estimates, published in the Federal Register when the BRS was implemented, indicated that approximately 85% of service members would be financially better off under the blended retirement system army because most do not serve a full 20 years. For those who do serve 20+, the reduced pension is offset by decades of TSP contributions and compound growth.
How to apply this: If you are in the legacy system, calculate your expected TSP balance under BRS using the TSP's retirement calculator and compare it to the pension reduction before assuming High-3 was better.
Frequently Asked Questions About blended retirement system army
When does the Army BRS government match actually start?
The automatic 1% government contribution starts after 60 days of service. However, the matching contributions — the additional 4% — do not begin until you complete two years of service. This means a soldier who contributes 5% from day one still only receives the 1% automatic contribution until their two-year mark.
Plan your finances knowing the full blended retirement system army match kicks in at year two.
Can I opt into the blended retirement system army after 2018?
No. The opt-in window for active component soldiers closed on December 31, 2018. Reserve component members had a slightly different timeline, but that window has also closed. If you did not opt in, you remain under the legacy High-3 system permanently. The only exception applies to certain service members with breaks in service who re-enter after 2018.
The blended retirement system army opt-in window for active component soldiers closed permanently on December 31, 2018.
What happens to my TSP if I leave the Army before 20 years?
Your TSP balance belongs to you. You can leave it in the TSP, roll it into a civilian 401(k) or IRA, or withdraw it (with potential tax penalties if under age 59½). The automatic 1% and matching contributions are yours after meeting vesting requirements, which under the blended retirement system army is two years of service.
This portability is the core advantage over the legacy system.
Is Continuation Pay guaranteed under the blended retirement system army?
No. Continuation Pay is not automatic. You must apply during your eligibility window (typically years 8-12 of service) and agree to four additional years. The amount varies by year and military occupational specialty. Some soldiers miss the window entirely because their unit never briefed them. Check MyArmyBenefits annually once you pass year 7.
Under the blended retirement system army, Continuation Pay is never guaranteed because you must apply and commit to four more years.
Can I change my TSP contribution percentage after enrolling in BRS?
Yes, you can adjust your TSP contribution at any time through MyPay. Many soldiers increase contributions when they receive promotions or annual pay raises. Under the blended retirement system army, the key rule is simple: never contribute less than 5% of base pay, or you leave government matching money unclaimed. Changes typically take effect the following pay period.
Conclusion
The blended retirement system army rewards soldiers who understand its mechanics and take action early. Here are the key takeaways:
- The government matches up to 5% of base pay in TSP, but only if you contribute at least 5% yourself
- The full matching begins at two years of service, while the automatic 1% starts at 60 days
- Continuation Pay at years 8-12 is a substantial bonus many soldiers miss
- Your TSP balance follows you if you separate before 20 years — a safety net the legacy system never offered
- The opt-in window for pre-2018 members is closed; new soldiers are automatically enrolled
Your next step: log into MyPay today, verify your retirement system code, confirm your TSP contribution is at least 5%, and review your fund allocation through the Thrift Savings Plan website. Fifteen minutes now can mean tens of thousands of dollars at retirement.
