Helen sends her SA return to us on time and it shows a liability of £50,000 which she pays on time. An enquiry concludes that the liability is understated by £25,000. The caseworker believes that and inaccuracy penalty is due. However, the caseworker is also aware that the additional tax, if paid late, will attract a surcharge under TMA70/S59C
Scenario 1 (Inaccuracy penalty higher than late payment surcharge)
| Inaccuracy penalty | = 25% |
| Surcharge | = 10% |
| Inaccuracy penalty 15% (25% - 10%) x £25,000 | £ 3,750 |
| Surcharge 10% x £25,000 | £2,500 |
| Total Late Payment Surcharge & Penalty | £6,250 |
Scenario 2 (Inaccuracy penalty the same as late payment surcharge)
| Inaccuracy penalty | = 10% |
| Surcharge | = 10% |
| Inaccuracy penalty 0% (10% - 10%) | £ 0 |
| Surcharge 10% x £25,000 | £2,500 |
| Total Late Payment Surcharge & Penalty | £2,500 |
