The Four Tier Boundary Danger Zones in April 2026
Here are the exact salary crossing points to watch in 2026/27. If your 2025/26 salary was close to any of these thresholds before the 3.3% rise, you may have crossed a tier.
Danger Zone 1: Tier 2 → Tier 3 (£26,831 → £26,832)
Rate change: 6.5% to 8.3% Extra cost of crossing: approximately £38/month
Who is at risk: Band 3 staff at mid-to-top of band, Band 4 entry-level.
In 2025/26, Band 3 top was £26,598 (Tier 2). In 2026/27, Band 3 top is £27,476. The Tier 2/3 boundary in 2026/27 is set at £26,831. Band 3 top now sits above this boundary — in Tier 3.
Affected staff: Band 3 at the top of band (2+ years service) who have moved from Tier 2 to Tier 3.
| Before (2025/26) | After (2026/27) | Impact |
|---|
| £26,598 at 6.5% = £144/month | £27,476 at 8.3% = £190/month | Pension ↑ £46/month |
| Gross pay rise: +£73/month | After pension jump: actual net gain | Much less than expected |
Danger Zone 2: Tier 3 → Tier 4 (£32,691 → £32,692)
Rate change: 8.3% to 9.8% Extra cost of crossing: approximately £49/month
Who is at risk: Band 5 mid-band staff whose 2025/26 salary (£31,049 to £33,487) now falls above £32,691 after the rise.
In 2025/26:
- Band 5 entry: £31,049 → in Tier 3 (8.3%)
- Band 5 mid: £33,487 → in Tier 4 (9.8%) — already in Tier 4
After 3.3% rise in 2026/27:
- Band 5 entry: £32,073 → still in Tier 3 (8.3%) — just below the £32,691 boundary
- Band 5 spine point 1+: £34,592 → in Tier 4 (9.8%) — already crossed
The boundary crosses affect Band 5 staff at the entry spine point who already received previous increments pushing them between £31,600 and £32,691 in 2025/26. After the 3.3% rise, they land in Tier 4.
Danger Zone 3: Tier 4 → Tier 5 (£50,060 → £50,061)
Rate change: 9.8% to 10.7% Extra cost of crossing: approximately £47/month
Who is at risk: Band 7 staff at mid-to-top of band, Band 8a entry-level. This is one of the most impactful crossings because it coincides with the 40% income tax boundary (£50,270) — meaning staff here are also potentially entering higher-rate tax simultaneously.
In 2025/26:
- Band 7 mid: £50,273 → already in Tier 5
- Band 7 entry: £47,810 → in Tier 4
After 3.3% rise: Band 7 entry: £49,387 → still in Tier 4.
The crossing risk here is for Band 7 staff at a spine point that was between £48,470 and £50,060 in 2025/26. After 3.3%, these staff cross £50,061 and hit Tier 5.
Simultaneously, if their salary crosses £50,270, they also start paying 40% income tax. The combined effect (higher pension tier + higher rate tax) can mean the pay rise adds almost nothing to take-home pay.
Danger Zone 4: Tier 5 → Tier 6 (£63,210 → £63,211)
Rate change: 10.7% to 11.6% Extra cost of crossing: approximately £62/month
Who is at risk: Band 8a at top of band, Band 8b entry. In 2025/26, Band 8a top was £62,682. After 3.3%: £64,750 — now in Tier 6.
