Sutton-Specific Back-Tax Items That Matter
Commuter landlord Section 24 phase-in
Multi-year BTL cases spanning 2017-2020 need each year's correct fraction (75/25, 50/50, 25/75, 0/100). Higher-rate landlord cases shift materially per fraction.
NHS pension annual-allowance charge
60,000 pound annual allowance from April 2023 (was 40,000); taper for adjusted income above 260,000 pounds. Multi-year cases for Royal Marsden / ICR consultants need per-year calculation with carry-forward.
RSU vest-date valuation
RELX, Subsea 7 RSU vesting valued at vest-date market value for employment-income tax (PAYE captures it). Subsequent share sale CGT uses vest-date as base cost; per-year Annual Exempt Amount applied (12,300 then 6,000 then 3,000 pounds).
Personal Allowance taper
60% effective marginal rate on the 100,000 to 125,140 pound band. Sutton commuter incomes commonly fall in this band; HICBC at 60,000 (was 50,000 pre-April 2024) compounds the picture.
Royal Marsden / ICR Consultant Back-Tax
For Sutton consultant clinicians at Royal Marsden NHS Foundation Trust and the Institute of Cancer Research with multi-year unfiled cases, the back-tax computation includes per year:
- ·NHS PAYE income Captured via RTI; reconciled per year.
- ·Private practice income Net of allowable expenses (indemnity insurance, GMC fees, equipment, CPD, room hire, professional memberships).
- ·NHS pension annual-allowance charge Per-year calculation using that year's annual allowance and threshold; carry-forward of unused allowance from prior 3 years; scheme pays election if applicable.
- ·Higher-rate pension contribution relief Private pension contributions claimed at higher-rate via SA.
- ·Research grant or company income Where research grants ran through a personal company, parallel CT and SA reconciliation.
RELX / Subsea 7 Share-Scheme Back-Tax
For Sutton-resident share-scheme participants with multi-year unfiled cases, the matched accountant values each event per year:
RSU vesting
Vest-date market value taxed as employment income (PAYE captures it). Records the CGT base cost for subsequent share sale.
RSU sale CGT
Sale proceeds minus vest-date base cost equals gain; Annual Exempt Amount applied per year (12,300 / 6,000 / 3,000 depending on year). CGT rate at 18% (basic-rate) or 24% (higher-rate, post-April 2024 down from 28% for non-residential gains).
SAYE / SIP early exit
Sold outside qualifying holding periods creates CGT events. Different rules per scheme type; matched accountant applies correct treatment.
