Question 1 Nadeem is a duty manager at Ocset Ltd. His 4-weekly salary is 2,000 gross. Every 4 weeks 207 of PAYE tax is deducted from his salary. In 2020-21 he received a dividend of 2,600 and net loan interest of 880. As this year, the 2 salary payments fell in February 2021, on 14 February 2020 he felt very generous and made a gift aid donation of 200 to a local charity. The same date, he also invested 500 in SEED Enterprise Investment Scheme company. As his wife does not work, he claimed marriage allowances. Nadeem is not a Scottish taxpayer.
